I’ve waited my entire adult homeowner life for this.
Thanks for sharing!
Haha ya
Washable filters are more efficient than others because they filter out more particles. BUT... they are also much more restrictive than regular filters. Thew require a stronger fan to circulate the air through the furnace. The filter in your furnace may not be strong enough and fan replacements are $$$$
You only uses air filters in homes you own? Lol
Same here. Straight geekin 🧐🤓🤓🤓🤓🤯😲
Dude, I can't imagine the terror that the marketing staff must feel when they find out that you analyzed their products!

Thank you!
Lol they probably email him often
especially when they make up there own standards.
Something like: “PF approved!”
500 Watts!
"We're gonna test that"
lol! Oh yeah! LET'S!
As an HVAC guy, thank you for this! This is what I tell my customers every day. Yes, the higher rates filters will filter out more, but they're typically too restrictive. If you want more and better filtration, you need a wider filter. Sometimes you even need duct adjustments to accommodate higher filtration.
You are welcome!
@@ProjectFarm Why aren't there more filters that are 3-4 inches thick? Or even 6" thick?
I had an HVAC guy come out for a quote on a new system and vaguely remembering this video with 2"+ being less restrictive I asked him about it. He said they are MORE restrictive so I had to re-watch and confirm he was wrong.
The HVAC guy who services mine told me the same thing. He especially recommended the high- flow woven fiberglass type for summer central air use.
My friend, who’s an HVAC guy, has been recommending that I use the woven glass filters, saying I’m starving my units w/ the 3m 1900 filters I use. I guess he’s more concerned with airflow than filtering.
I have been using the 3M 1900 filters for several years. They are somewhat pricey especially when replacing them monthly. I was glad to see your tests show they do a good job filtering without too much flow restriction. As an software engineer, I greatly appreciate your rigorous test design.
Thanks!
You don't know that at all. Do a static pressure test on YOUR equipment and see what is really happening with those filters in.
@@kenthomas4668 To be fair, the filters here are being tested, not the system. No HVAC system is airtight around the filter's edges, so yes it will be lower in a system. But this is about the filter itself. A standard must be set, sealing it off completely as was done here makes the most sense to me. I want to know the filter's performance. A junky HVAC system could allow tons of airflow around the filter, those results wouldn't be valuable.
Too bad it's a poor test design. Rigorous doesn't help when it's in the wrong direction.
i am an hvac technician of 20 years 40k + service calls. youre doing the right thing. but dont change. the 3m 1085 or the 3m 1900 best filters hands down. every month is probably a little excessive. Do not ever go past the 1900 tho or else i can tell you it will absolutely F up your AC. the 2200, 2500 lose minimum of 25 percent of your air flow which is a full ton on a 4 ton. i have had a few hundred calls where those filters just cause tons of issues and typically they wont even work at all. The only reason that they even work is because enough of the air somehow is able to find its way around the filter. Thats when the air starts trying to pull air from the attic or the gap in the filter and just wherever it can because it dam sure cant out of those filters. it suffocates and causes the suction pressure to drop. And in the heat mode it will cause the system to overheat which can cause its own set of serious damages. Its hard trying to explain to a customer that their filter is garbage regardless if its clean or dirty. its just amazing how filter changing isnt standardized. i cant tell you all the dam problems i get from filter issues.
Do I have any reason to watch a furnace filter test? No.
Am I going to watch a furnace filter test? Absolutely I am.

@@ProjectFarm n
Hey buddy, great video! I work in producing filter testing equipment, and I really loved the dedication and effort you put into this video. I think your analysis in general was really informative. Something worth considering if you tackle filtration in the future is the relationship between contaminate accrual in the media and the buildup of resistance to flow through the media. The differential pressure curve to contaminate captured is a huge factor in filter performance that you could maybe tackle by aerosolizing the particulate into the air stream and then timing each filter to reach a predetermined change in deltaP.
Still, rad video, love your channel, I'll keep coming back.
Thanks!
Honestly this channel is incredible.

It would be helpful to compare the 1" honeywell filters to really compare the brands as opposed to comparing thickness.

Hi Thom. Is Best Air owned by Honeywell?
@@SeattleMK2GLI yes they are, overall 4 and 5" filters tend to be better overall over 1" filters across the board. Less area to work with compared 4" and 5" filters. Also I prefer to install them horizontally in the return instead of slammed against the furnace, easier to change and you have have a pile of debris in the return air boot.
I love 11 Merv and above filters.1inch. They make me rich. I'm an HVAC company. Those dense filters creates me many service calls. They restrict the airflow so bad it freezes up evaporators, they overheat in heating mood killing many compressors. I make a killing off these filters. I'm totally surprised air filter manufacturers haven't had one heck of a class action lawsuit against them. I've been working on heat pumps since 1988..
@@Bryan-Hensley I have worked as an expert witness tearing apart people like you. In short, what the situation almost always is is you are falling victim to sampling bias, connecting uncorrelated events, and you actually don't really care about your customers. You have no sympathy or empathy for why they would want better filtration than a crappy panel filter.
And a class-action lawsuit? Really? For what? For selling a product that has stamped and inked, traceable classification and performance test results from an unbiased third-party organization and testing labs telling you exactly what they will do and endorsed by your trade organization?
If your "solution" is basically stop filtering the air, then I'm sure as hell glad you don't work for my local water treatment plant! If people don't change their filter for a year and that overworks and their blower and their compressor starts slugging, then that's kinda their fault. ASE mechanics don't go around complaining engine oil filters are crap because my engine falls apart because I didn't change the oil and filter. That's basically what you are doing.
Another way to think about it: They have been making these filters for 30 years, and capitalism has kept them not only alive but very strong growth. Sol what's more likely: Someone is subsidizing these companies to stay alive and to silence all the ASHRAE and trade unions and such, or you just are bad at this part of your job.
I use the 3M 1900 filters and their performance in these tests was quite surprising to me, better than i anticipated. That surface area really helps, and keeps my allergies at bay. I think the largest detriment is that people do not change the filters often enough in their home environment
Thanks for the feedback.
Have you considered a room air filtration system (air purifiers) - they work very well and after you change out the filter and charcoal filter you will be amazed at what they trapped and what did not go into your lungs. We have a few in our house and have basically no dust on the furniture, so they really must be working.
Same here. So worth it
After seeing the performance, I plan to switch to 3M 1900's as well. The static pressure dirty is less than half the result of the filter I currently use! That's worth a change.
Add an iwave into your system and you'll be set
I love being able to see your videos as some of my search results for things like this. I go straight for them. Thanks man. Your vid’s help a ton.
Thanks and you are welcome!
I wish my furnace had a static pressure sensor that would notify when it’s above a threshold. Seems like a practical thing to add that would objectively tell you when you need a new filter.
It's easy to put one in on the return between the furnace and filter. General Aire G99 Air Filter Gage
Great point!
Mine apparently does -- the thermostat whines FILTER when it's not happy.
Pretty simple to just check your filters every couple weeks and see if its dirty
They make whistles to do that

As someone who works in the HVAC industry, I found this video technically accurate and really educational.
I'm starting HVAC training at 61 since I'm living in Texas and "retiring" in Florida.
Any advice for a new student?
As an AirFlow tech who worked for pharmaceuticals and hospitals, I too found that this was far better and more informative that anything else I have seen in the public view.
I would have liked to see things like ash, filtered with a mesh used as it is finer and also I would have liked to see the dust to be released while the fan was running. as a filter clogs in one area, other areas allow air to pass. deep pleats can store the flower at the valley while the peaks don't have any flower. releasing with the fan running would cause the flower to enter the higher velocity areas.
as a note, home air handlers should have space to 2 or more filters. air moves slower, catches more lint and lasts longer with lower pressure drop.
Well can you suggest which filter I should go with??
@@jacobhendrickson8935 From what I gathered at the end, choose one that has a lot of pleats and a low merv rating. Around merv 8 or lower.
@@jennifercohrsbabb4518 thanks, I did see that but had skipped through a lot. Was hoping he had some categorized winners

Thank you again for being an amazing consumer watchdog!
Air filtration in HVAC systems is a very crucial aspect and people don’t understand that most duck systems are improperly sized. if your duct is sized correctly even the most restrictive filter will be just fine because the surface area is large enough to compensate for the static pressure. But like I said they’re usually too small. So is an HVAC repair man I would recommend the 3M 1900. Excellent video as always A true professional. And a service to homeowners everywhere this is always my favorite channel. let me add that up until this video I generally recommended the least restrictive air filter possible I’ve even use the green one so I mean you’re influencing homeowners and professionals with your content. Granted it benefits me to for people to have dirty ac cause I get more service calls 😂 but I’d rather recommend quality products

As a pro HVAC guy, the number of times I've see 4 1" filters stacked on each other, in the place of a nice 4" filter, makes me sad.
I would have loved to see what 4x 1" filter on each other did on his static pressure.
What is weird is the higher Merv had similar starting resistance and less resistance when dirty. So correct me if I'm wrong, but damage to system, or underpreforming system could only be caused by a dirty filter, not a high Merv rating like is commonly suggested.
@@_RiseAgainstThe higher merv filters has vastly more surface area than the MERV 8 filters. They compensate for their restrictive media with more surface area.
If you can find a high pleat count 8, you'll have a very, very free flowing filter that doesn't cost so much

@@joelvarela4444 wood, electric baseboards, in floor heat, hot water radiators,
You and me both - I have never even seen a furnace in my life, as they don't exist here.. but can never miss a PF video :-)
Thanks for the great video, as always.
I installed and repaired HVAC systems for over a decade and quickly became convinced that the cheap, fiberglass 1" filters do only a minimal job of protecting coils and furnaces. They stop large debris, but a wet A/C coil will still eventually clog up with fine dust even if the owner routinely changes the cheap filter (and many do not). An inexpensive pleated filter will offer far better protection to your equipment, but will probably need to be changed more often as it will catch far more stuff than a basic fiber filter.
If you're buying a new HVAC system or building a new home, you should definitely talk with your contractor about filtration options, especially those that add little additional expense such as having the ability to use 2" filters. This gives people more options. We don't want to force people to spend a fortune on filters, but improved air filtration can have multiple benefits, including:
1. Longer service life and less maintenance for furnace, air handler, and refrigerant coil.
2. Fewer indoor allergens, which reduces suffering for those that already have allergies, but may not stop babies and toddlers from developing allergies (early allergen exposure might be beneficial). As an allergy sufferer myself, I definitely benefit from filtration.
3. No need to routinely clean duct system, which is an expensive and potentially damaging job often done by contractors who may not be licensed and who sometimes use exaggerated claims to frighten people into having their ducts cleaned.
4. Less overall household dust, but vacuuming should still be done regularly as it keeps a lot of dust out of your potentially expensive furnace filter(s).
5. Reduced or eliminated need to purchase and operate standalone HEPA filter units.
Filter upgrades don't necessarily have to cost a fortune. If you choose somewhat better filters that have a lot of pleated surface area, you may be able to increase your filter change interval. While a single "good" filter is usually more expensive than a 4-pack of basic filters, the reduced need to go into the attic or crawl space plus some of the benefits listed above may make this a reasonable investment.
No matter what kind of filter you have, if a filter "looks" dirty, then it's probably past time to change it. If your filter has an opaque layer of dust on it that can rub onto a finger, then you should probably *halve* your current change interval (double the frequency). Such a layer *greatly* increases the workload to your blower and reduces airflow, which can then cause A/C freeze-up and potential compressor damage. Dirty filters can turn out to be *very* expensive.
MERV8 is often a fair compromise, as upgrading to MERV11 or higher filtration levels will usually require the consultation of a licensed expert. I do not recommend over-spending on air filtration except in cases of real medical need and I like to keep in mind that modern societies in rich nations seem easily attracted to over-cleaning and over-sterilizing their environments. Those with airborne allergies may substantially increase their quality of life with better air filtration, however.
You are welcome! Thanks for sharing.
Most furnace manufacturers like .5” w.c. Total static that’s measured before ac coil and after filter After taking in account for supply and return duct and ac coil static drop for filter is about .15”
I work as an HVAC technician. I agree with everything you have mentioned. The benefit of a 4 inch filter that can go 6 months, outweighs the costs.
What’s your recommendation for 1” filters I can buy today at Home Depot? Small home in Los Angeles, and I already have air purifiers running. I was using Honeywell Merv 11 FRP 9, but I’m thinking that’s overkill, and I might be damaging the HVAC system?

I did not have any problems during the 16 years of ownership. I currently have a smaller home I had built and I'm still using the same Flanders easy Flow filters exclusively.

Thanks for the test. I got an electric furnace / AC combined installed about 2 years ago (replacing an oil furnace). Initially the tech installed an ElectroDust washable filter and told us that this was the only filter we should use. I noticed after a few washings (every month) that the air quality dropped throughout the house. A person living in this house has extreme chronic breathing problems and I have seasonal allergies. A few months ago, I switched to 3M MPR 600 just out of curiosity and I was astounded at the amount of debris that they would collect compared to the electrostatic filter. Within 2 days of installation I could easily notice a difference in air quality throughout the house (no fumes, no headaches, no nose congestion or sneezing). An HVAC tech was here about a month ago and he removed the 3M and put back the ElectroDust claiming the 3M was causing too much restriction and making the blower whistle. Of course he doesn't care about air quality. What should I do ? I'm through with electrostatic filters. I'm tempted to try out a 3M MPR 1900 even if the tech would not approve. Have you tested the K&N washable filters ? The Castle MERV6 and MERV 8 filters ?
Any updates?
Sounds to me like in your situation you're going to have to pony up to make a 2" or even thicker filter possible. Either that, or go with a lesser filter and add internal air cleaners inside the home. That HVAC guy Wasn't Wrong. These furnace filters are not supposed to medically clean the air, they were only intended to protect the unit.
HVAC Tech who knows a thing or two about a thing or two. Can confirm everything that has been said here. Glad someone finally made this video.
Thanks!
This is probably one of the most informative and impartial CZcams channels In e ever subscribed to. Thanks for the fantastic content!
As always, well planned and executed assessment of the filters. I was hoping to see a summary guide concluding the findings of the previous graphs. So, what's the better 1" filter buy?
Congrates amigo for many of your well laid out videos. Your specific setups show your amount of time involved and keeping to the accuracy of testing. To see up front your results compared to manufactures results. I once thought there was a little-known fact called "truth in advertising"?
Well done.
Thanks!
Man this channel is awesome. Every once in a while I have to stand back and appreciate how great these videos are. Not only are they a tremendous consumer resource (the best consumer resource anywhere, I won’t even say that’s an opinion, I consider it a fact,) but they are also just plain entertaining, at least to me. I could watch PF test products until there were no products left. There’s a ton of niche stuff that I hope he gets to someday but I can’t expect them, we already get so much from this man. Just think how much combined money he has saved people from these videos, it’s probably into the millions of dollars.
Thanks so much!
Great video!! I work in the air filtration industry, but even we don’t see real life testing like this with such a variety of filters.. good job!
Thank you!
Wish u had tested the k&n home filter as well I’m currently using it and seems to be working great. Thanks again for all ur test u do a great job
Excellent experiment, interesting outcome! High time somebody did this, thank you SO much! 😊
Thanks and you are welcome!
I've been an hvac technician for 4 years, this video was a fun watch. I can tell you from experience that most systems (at least systems that I've worked on) can't handle a 1 inch filter with an 8 merv rating. In general an hvac system is designed to run at .5 overall static. Thats the filter, A/C coil, overall duct work friction, and even the furnace itself. When the system is initially designed it can be designed to handle a high merv rated filter. In reality systems aren't designed to handle a high merv filter. As of 2020 a new motor technology called constant torque comes standard with every furnace. The name speaks for itself but I will briefly explain why its a game changer. Before 2020 PSC motors were the industry standard motor for nearly all furnaces. PSC motors are great but their output CFM is determined by static pressure and the output can range wildly as static pressure changes. Filter get dirty, you get less air. Filter is brand new, you get more air. Constant torque is quite the opposite. A constant torque motor can maintain the same CFM all the way up to .8 static. The way this is done is too complex to explain for a CZcams comment but the result of the technology is a system that is able to deliver a constant CFM even as static (resistance) changes. Additionally, in high altitude areas where the air is thinner, constant torque actually puts out more overall CFM to maintain a constant mass air flow. That means the system won't be at a deficit simply because of thinner air.
Once again, great video, very informative. Hope I was able to teach someone something with this lengthy comment.
Thanks so much! Thanks for the feedback.
@@ProjectFarm My pleasure. It was extra special to see you doing HVAC tests.
This is good information and now has me wondering about my setup. I'm using the 3m Filtrete 2200 (Merv 13). My furnace is about 16 years old although i just had the A/C side of it replaced last summer. We chose to run the 2200 filters because of bad allergies but its sounding like this may be a bad idea for functionality? What is the best possible solution to filter out the most debris and allergens while maintaining heath of a furnace? From what i'm reading maybe the 4" filter?
@@klay590 Thank you for the reply and great information. Ill look into this.
Additionally, installing a device like this combined with the healthy climate filtration system, you will have (at least in my opinion) the best IAQ solution available.
Just bought my first house and am still learning a lot about being a first time home owner. This video couldn't have came out at a more perfect time. Thank you.
You are welcome!
Thank you! Buying an air filter today, so glad you did testing on these!
You are welcome!
Thanks, as always your videos are very informative.
i love that you do research on WHAT each rating means and how it came to be to give all of us a deeper understanding. i really respect that!
Thanks so much!
Most useful channel on CZcams. No BS and stuffed with information. Thanks project farm for the years of great content
Thank you very much!
Agreed.
I came back to this video a year later to figure out what filter I wanted in my return ducting to help out my dynamic filter system and I decided on the 3M 1900. Thanks again!
You are welcome! Thanks for sharing.
Give this dude a gold star this is the best video I've seen on air filters and I learned a lot.
Wow, thanks!
I'd love to see a rattle can clearcoat video, testing clarity, durability, cost, ease of operation etc
And compare to real automotive clear coat
Great suggestion! Thank you.
@@ProjectFarm also the same for polyurethane coatings for wood would be nice - especially for outdoor furniture!
If you do it please test yellowing during exposure to UV also.
wow that would make a great vid
Have you considered summing up with a “best bang for the buck” at the end of these tests?
Thanks for the suggestion.
Best bang for the buck is to see if it's possible to convert your filter to a 4", then choose the filtration capability depending on your needs. A 4" filter will last way more than 4x longer than a 1", as it can hold at least as much particulate as four 1" filters while still allowing adequate airflow. By the time the 4" has clogged up to the point that it's adversely affecting airflow, you've captured twice as much particulate or more as an identically rated 1" filter. It's also more cost effective, as a 4" filter generally isn't 4x as expensive as a 1". I believe the filter I use is about 75% of the cost of 4 pack of 1" filters (same brand, same rating), and instead of changing it out in 3-4 weeks I'm changing it out every 6-9 months. My ducting just past the filter has a section that oil cans when too much vacuum is on it, so when the filter is clogged I hear a loud THUNK every time it turns on and turns off...that's when I know to change my filter. It hasn't happened yet with a 4" filter, so I just change them out as more of a regular maintenance schedule than out of necessity.
@@ProjectFarm So...... what 1" filter would YOU choose should you need that size? I have gone with your recommendations frequently in the past and would like to in this case.
Thanks again for your efforts.
@@wharfrat53 From what I was able to see here, the 3m 1900 looks promising
I did a spreadsheet. Best value (cleans, low pressure loss, cost, life) is the 2"Honeywell Best air at $5.48. If you can only fit a 1", 3M Filtrete 1085 at $11.97 or Filtete 1900 at $19.97 for longer life. Cheap and not bad, 3M Filtrete Basic for $4.97
I appreciate the effort you put into making this, so much!
Thanks so much!
Awesome comparison!! Thank you again!!!
Any chance of testing home room air purifiers? Please and thank you. Keep up the great tests!! 👍🏼 cheers from Oregon 🌬💨💚🌬💨💚
Thanks and you are welcome! Thanks for the suggestion.
Do you know those commercials that tease you about turning into your dad?? That hit home lol I’m watching a video about home air filters and I made EVERYONE in the house pay attention and listen 😂😂😂😂😂😂😂
lol Thanks for sharing.
Now follow up with a dad joke, like, "i like project farm, because he's good at filtering out the nonsense."
This man made furnace filters interesting for 13 minutes. Outstanding
Thanks!
Excellent review. You reviewed all the concerns I have with furnace filters especially air flow and filtration that is best for furnace longevity.
Thanks Thanks for the suggestion.
As an ac tech this is an amazing design and demonstration. It will help me recommend filters for my clients. Thank you project farm.
Wait a minute! Did you test using sifted or unsifted flour? LOL :-) Truly incredible testing as always! Loved the video. A++
What about polarized and statically charged flour? lol . I agree!
LOL
I was kinda expecting a lawnmower engine powered sifter to make its way into the video
Just sift it with that first filter...assuming it will be finely enough sifted...
Now that others have mentioned the lawnmower sifter, you could have used the lawnmower to run the fan too. 😂
VERY informative. I really needed to understand this stuff. Another A+ job that I missed 2 years ago.
Thanks!
The most important thing here that everyone's is missing, is that frequent filter changes are what will extend the life of your system. Most installs have the air balanced upon installation and the static pressure is checked to be within specs of the manufacturers requirements. I believe as long as you are using a pleated filter and change frequently then that's all you need. Leaving clogged up filters will only increase static pressure and lead to premature failure.
Thank you for the feedback.
And there's the GOTCHA in furnace "lifetime" warrantees on heat exchangers- read the fine print and you'll see it details filters and replaceing filters, their "gotcha" get out of covering you is when they come back claiming you didnt change the filter enough and it's YOUR fault the heat exchanger cracked. SO how do you PROVE you changed that filter every week (or whatever)? you can't
Guy tried that at the shop where I work, claimed the filter wasnt changed enough and the heat exchanger cracked because of that and getting overheated, so the warrantee was void!
Well I came back on him with calling his claim bullchit because I changed the filters every Monday- first thing I do when I get to the shop, and then I said "do you mean to tell me that this expensive furnace doesnt even have some air flow/heat sensor in it that shuts it down if the filter is clogged and the unit gets too hot to protect it from damage?? THE most expensive part in the furnace, REALLY?"
And then I read the warrantee to him and said "SEE? right here is how they worm out of warantees- by claiming the damage is from not changing filters enough, so of COURSE they arent going to put a sensor in to prevent the claimed damage- it's their OUT to worm out of the warantee!"
He didn't have a response and left.
Oh and another gotcha, like Goodman, you can buy the furnace and install it yourself, but forget the warrantee- it requires "professional installation" which it estimates is going to be $3000- $4500, LOL, I bought a new Goodman furnace last week for $1600 to install myself, WHY would I pay $3,000-$4500 for a "pro" installation I can do myself? and even if the thing breaks down I could buy TWO new replacement furnaces cheaper than the install cost for one to get the warrantee.
how frequently?
@@randomrazr really depends on the home, how many people/ animals you have and how frequently you clean. Between 1-3 months is pretty common. If you have an area that isn't occupied then you may be able to go 6 months.
@@ghmsadam i know the 3m filters say 3 months
I love that you reply to basically everyone, even if it’s a basic reply you still do it which is really cool
Thanks!
A while ago I found out that if you comment enough in a short time span, you need to complete captchas, I wonder if project farm has to do that.
This guy is great ! The amount of time you spend on these test for us is greatly appreciated ! Thanks man
You are welcome!
I know I’ve seen this one before, it’s always worth watching again, because I can’t always find the filters I want so need to pick the next best, thanks.
Thanks for watching!
Thank you for recording and posting this valuable educational video.
Thanks!

@Mia L He should add a conclusion but he doesn't and that is only thing that is wrong about his videos.
@@moltenpros - thanks; thought I was the only one who felt that way.
@Mia L @@moltenpros A final conclusion might be improper, in addition the evidence is there , replete, you shouldn't need him to tell you which one is better or a better value, that's what all the testing and data is for... 'merica
@@cjlion7081 Not everyone understands the technical data or what the tests actually mean. So when you get to the end of the video you learn that you have to watch it again to figure out which one is the best.
@@moltenpros hoped you rethought this...
A final conclusion might be improper, in addition the evidence is there , replete, you shouldn't need him to tell you which one is better or a better value, that's what all the testing and data is for, but promoting one over the other isn't ethical, and this guy maintains that, It's up you, the viewer to calculate the outcome of his testing to foster unbiased objectivity
You're the man Todd!
Thank you and hope you enjoy the video!
This channel is incredible. I refer to it before purchasing many items.......
Thanks!
Ive needed this for years thank you
You are welcome!
This is awesome! Seems such a mundane thing to test, but I am one that will stand in the filter area of the store trying to figure out which one is the best bang for the buck. Man I love this channel!
Thanks so much!
Sometimes what you don't see is the best thing to test.
@@ProjectFarm Actually, Thank You Very Much as without your content we wouldn't know half of what we all know now!
Awesome Service Sir!!!
Oh how cool is this. I literally was just at Home Depot getting furnace filters the other days and wondered if these were as good as they say they were. Todd is going test that, we the people are going to know and honest result.
Thanks!
Thanks, **interestingly my Landlord has used HOME DEPOT filters, in my Apartment 16x20x1: had **no Ratings on them two years ago: installed for approx. two years plus( a Landlord’s supposedly Maintenance Help: Annual Change,***!).....though another Worker changed to 3M PLEATED FILTERS TWO YEARS AGO... always interesting !
Put the high Merv ones in. Your HVAC contractor will love making money off you. I make a killing off of service calls and compressor replacements because of those filters.
@@Bryan-Hensley lol gtfoh. That's good to know tho. I 👍
Thank you for setting all this up and helping people out.
You are a damn angel
You've done a hell of a service. Thanks.
You are welcome!
How can anyone give PF a thumbs down? These videos are so informative, even if it doesn’t pertain to your needs, and he’s very creative with his methods! I’ve bought items based on this man’s reviews. Thanks Project Farm. 👍🏻
I appreciate that!
They gave it a thumbs down because they spent a bunch of money on the wrong filter. HAHAHA
I suspect it is accidental. I have accidentally clicked the icon when scrolling.
They are negative ned's I guess. I'm being nice. Pf is the best. Been watching for years
