How to Determine Correct Furnace Filter Direction

A furnace filter has one side that allows it to “breath” fresh air through, while the other side traps dust and particles from the air. If improperly installed, the filter will inhibit air flow forcing your HVAC system to work harder. The result is not only a less efficient unit but could potentially damage your HVAC system.

I think it's great that Elon Musk is branching out and helping folks learn about their HVAC system.

Funny 🤣

😂😂😂 Now I have to watch it twice because I missed the whole thing laughing 🙈

[@CYMotorsport]

My only recommendation after returning to this atleast once a year: Blake, or whomever, should avoid using "airflow". That concept is precisely what's confusing. It's predicated on understanding how the systems work. If I knew that, I wouldn't be here in the first place haha. so saying "it should be pointed direction of airflow" is maddening even today now that I thoroughly understand.

[@sethbrown7550]

Always point the arrows toward the heating/cooling unit

[@stoneysignorina2473]

that makes it more simpler. if I knew about air ducts, returns and direction of air... I would already know about the filter direction.

[@tsquare852]

No wonder the entire apartment got hot when my bf replaced the filter

[@PeteStMartin]

Thank you. That was a better explanation.

[@DoleyLama]

Not all hero’s wear capes. This is the answer we needed

[@worldhealthrn]

THANK YOU!!!! WHY DON'T THEY JUST SAY THAT?!! What are you supposed to wet your fingertip and then stick it down in there to figure out which way the air is blowing?! So annoying!

[@markschneider2472]

I was thinking the exact same thing and then I saw your comment. Nice work!

[@carolinda688]

Excellent product!

[@JY-tq4ir]

best explain, using this

[@dougpassat]

Thank you.

[@anita3.]

Simple and easy to understand

[@Temarama7]

A small magic condo furnace with filter going in flat on top fan under filter arrow goes up as airflow going up

[@ashcash5035]

Why is this so hard to figure out. My unit doesn't look like that. I cannot find a video anywhere

[@dougprentice1363]

Ash cash. I held a dryer sheet where filter goes. It showed direction of air flow. Also I saw on another video, the flow direction is always towards the furnace, regardless of what system looks like.

[@JohnWhiteECU]

AIR FLOWS out of your vents, the filter, filters air at the intake, so the arrows point towards the way the air flows into that air handler unit in your home/apt/condo, etc

[@bunnybubs757]

The arrow always points towards the bigger , larger piece , that’s going to be the actual furnace .. they use all different names to confuse us.. blower motor etc.. the smaller piece is the duct
Arrow points towards big furnace

[@gotchocol8]

Thank you 👏

[@kathyb1020]

I just checked and I have filter in correct way. I don't understand why my house is cool in the mornings and gets hot in the afternoon in winter. Thanks.

[@billjonesnation]

I have same problem. Any luck fixing yours ?

[@kathyb1020]

@@billjonesnation I bought a new A/C and furnace. My house 20 years old this year.

[@PepperWilliams_songcovers]

I had to watch the video more than once because the jazz pianist (who sounds like Vince Guaraldi), was 'kicking it so hard' that I couldn't listen to you:) Good taste my friend in your music, and after three times around, I finally got what you were saying!!

[@q1o2]

What if the arrow is gone or not printed. Like just looking at the face of the filter, how would you be able to tell.

4th video and still not the answer, My unit has the filter tray about 2 feet from the floor, no side area.

[@blisterpacman]

my filter doesn't have an arrow and it doesn't go inside ways..

[@skyandcambray3127]

What about the filter behind you?

[@jaydenchandra8723]

Hello not all filters have arrows. Ugh no help

[@alcoury332]

filter has no arrow. but one side has some kind of membrane. any suggestions? Thank you

[@joseebalboa3177]

Chiken wire looking side. Will face up.

[@traceycancio1795]

@@joseebalboa3177 Does the metal part touch the furnace?

[@Vegasvip999]

Does no one have an air filter up stairs that doesn’t show the furnace????

[@robertmaimone8733]

Get a air purifier in addition to change your regular filters

[@briancdykstra3793]

Poor camera work. Cannot dertermine where the arrow is pointing.

[@educationX]

Thank you Elon

[@maxinerawls8387]

That did not help me at all. My unit is in my attic and looks nothing like his.

[@ivantheDIYguy]

Please watch my video it will explain everything to you about the arrow.

[@PeteStMartin]

What?
How about showing the damn arrows? I didn't understand any of what you just said.

[@Googaliemoogalie]

it seems that Elon Musk is a better speaker now

[@kimstevens8835]

No arrow!1
