I remember reading somewhere that you’d need roughly 160 large plants in a 2 bedroom flat to have significant measurable impact on the air quality
really ? nasa recommend only 16-18
@@sdqsdq6274 depends on size of the flat and plants (size, leaf area). No home is airtight and that will have an impact as well, another factor is how bio active your soil is because bacteria and fungi in the soil decompose the absorbed toxins. I have over 50 plants with about half that are ‘air purifying’ in my 70 square metre flat and I wouldn’t bet a single dollar that my indoor air is significantly purer than my neighbour’s
Snake plants easily can do that NASA claims
Not really.
I would suggest a living wall where air can flow though and around the plants as a possible method for air improvement. I agree that indoor air cannot really be cleaned with plants but having say a hundred plants in a wall would help air quality. Also just the feel of something living and green will definitely improve your mental state.
agreed! I still love plants and will keep buying more. I love the idea of a living wall that air passes through!
Will it safe about the CO2 that the plants will produce? I plan to plant it inside my bedroom which is mean a place where I will sleep.. but scare the co2 the plant will produce will not good for my health..
That's a good idea. Which is what I am thinking... ... similarly so.
I am sick and tired of a land of garbage polluting carefree with evil police and useless government wasting everyone's time and allowing second hand smoke and pollution to kill the public especially after Covid19 shows up. Very bad.
Things got very bad recently, so... ... here's the power of science.
@@kikyozu It can solved by using lamps at least with 30w bulbs on, while blocking the light from you.
Well if the entire house is OPEN then of course plants are ineffective. But if you are a single person living in an enclosed space like a rented one room apartment then plants are definitely effectlive in that space.
Even in apartments with the windows closed your building is pushing in fresh air, if we lived in rooms that were air tight we would suffocate and die over time, all houses, appt, and other living spaces exchange air at a high rate so we can live and breath comfortably
@@TechplantChannel Yes that sounds logical and right. But I would like to see a study carried out to determine just how much air is exchanged out and if house plants contribute anything. Eg: 5-10% of air even if all the air is exchanged out over time..
@@TechplantChannel well that fresh air you mention is subjective , unless you live in the countryside ? fresh air in Nyc ?
Will it safe about the CO2 that the plants will produce? I plan to plant it inside my bedroom which is mean a place where I will sleep.. but scare the co2 the plant will produce will not good for my health..
Just happen to come across this video. From someone who has to read scientific journals for a living, the NASA experiment has too many bias. They only use certain types of plants that are common and accessible to the public, they didn’t mention the number of foliage or even the health of the plants that they use and they didn’t mention the position the plants were situated in the indoors. The air dynamics (movement and pollution) were not mention as well.
A few similar studies with more cohesive design was done in Korea and did show improvement of asthmatic symptoms in people living with plants in their house. This time, they document the size of the plants and the types of the plants. They did measure the indoor air quality but still some bias were present as well.
Basically the conclusion from these studies are; Plant DO purify the air; HOWEVER, there are other factors that play a role in this as well:
1. The size and health of the plants.
The bigger the plants, more foliage that it has, the better it is to purify the air.
2. The number of plants to the cubic measure of air in the confined space.
More plants are needed to purify more air. You cannot expect a small pothos with 10 leaves to purify a mansion’s worth of air.
3. Air dynamics
Movements of the air, the presence of already pollutants in the air, the production of pollutants in the air all would play a role in how great the purifying effects can be seen.
Basically, a clean house that does not use any insecticide and have no smokers inside would have a cleaner air quality to begin with as compare to a house with smokers and heavy usage of chemical insecticide. Then, there are other external factors like the location of the house if it is close to a factory/open burning area/mechanic workshop/etc.
So don’t discourage people from having indoor plants. If all else fails, plants ARE proven to reduce anxiety and stress levels.
Im not discouraging houseplant ownership quite the opposite with this channel. Also I mentioned that the plants did remove things from the air, but the crux of every one of these experiments is how houses work. They exchange air way faster than the plants can filter. I have another video too about plants producing oxygen, they only do this when they are doing photosynthesis. So most houseplants have less than idea light, which would reduce the plants "filtering" abilities. On top of this most houseplants are in the corners or along walls where there is little airflow. Houseplants are great and i love them, but they are hardly an effective way to filter a houses air.
Thank you for leaving this comment!
@nando's very well said !! thanks for your comment im enlightened ❤️
I'd love to read the study if you know the name or research university that released it.
This would be great for a kid’s science project
True!
Thank you for not going the clickbait direction most plant based youtubers have gone. Respect!
i ratted out the clickbait with my own clickbait lol
So is their any benefit at all to having these plants inside or is it more beneficial to plant them outside for our environment? Or both. I have a nice desert garden that’s focused on the hot climate of Arizona so a lot of aloe plants cactuses etc but o wouldn’t mind having snake plants etc inside I enjoy the smell of live plants my work has a river room and plant room the plant room is basically a giant green room with napping pods I really like going in there to help clear my head but idk if the whole fresh air thing is just a placebo there.
What doesn't make sense to me is that , isn't activated charcoal a key component to water and air purifier filters anyways? Did they do studies to see if it works without the charcoal? And maybe with only charcoal so you can compare them?
Hello, I had a few questions. What did you use to validate you're indoor air quality or are you just hanging your hat on average number of air exchanges? As passive house construction and spray foam make out homes tighter and tighter what air exchange number would change your mind based on the filter rate you observed?
What kind of substances in the air does this air purifier filters?
I have a small 60 m2, grown floor apartment in the city and I am trying to find out if adding specific plants to my home would help... but you are saying that adding plants would not do anything at all to improve the indoor health of my flat?!
it will make your brain health good because plants are awesome, but it wont be able to filter your air in any significant way. BUT you should still go buy plants. they are fun and they bring happiness
@@TechplantChannel Thank you for your reply! :) Plants are awesome! :D
There is a TED TALK about this and it is only 4 mins long - I would love to hear your "take" on it...
It is called: "How to grow fresh air | Kamal Meattle" on youtube... How would you explain their findings? :-)
What type of tree purifies the air the most?
What plant do you use
If I will test the air that this purifier releases with an air quality monitor, will the test result of the air is positive?
That's wonderful! We created our Natede line based on this study. But we also added the photocatalytic technology too 🌿 good job!
I usually sleep with close windows and I don't have air condition, then this would work better, right?
I'm looking at a way to clean the air cause a suffer from Rhinitis, allergic, I really appreciate if you can tell me if there is a way to make this works, plants are cheaper than air purifiers.
i think the plants could help, but they may make it worse because you could get molds and fungus growing in the dirt which may cause your Rhinitis to get worse.
@@TechplantChannel Oh, I see. Really appreciate your response.
can you test the pots of airy? cause they built pots based on that nasa study and some other institut testet those pots too and it seems to work but Im still skeptical
Those are pretty pricey for me and they are international shipping. The plants and pots DO filter the air. There is no doubt that this study is true. The problem is when you introduce the concept to a house. Modern houses bring in air from outside completely switching out your air 6-8 times an hour. so say the plant filters 20 liters of air in an hour. your house will have already switched that filtered air with brand new unfiltered air from the outside.
So its not a matter of the plants not being able to filter air its just that your house will push so much air in and out of your house that the filter cant do any noticeable difference to your air quality.
Also something that i thought of while doing this based on my other normal pots. A lot of my soil has fungi, and mold in it along with other allergens. So you could possibly be putting mushroom and mold spores into your air with these filter pots. Possibly causing your air quality to get worse.
Techplant thanks for your detailled answer. I was thinking about building something similar to those pots but I didnt think of mold and fungi. that could be „dangerous“. It probably needs to be a different kind of soil, not the common one which could also have some bugs in it. I need to make more research :)
uhmm... I think you need some more experimentation on this one..., I have a friend who is a profesional chiropactor and has a not so small office where he consults clients every day, lots of them, and he can clearly "smell"/percieve the difference in air quality if he has one big snake plant in his office or if he takes it out.
Very interesting
Wait... isn't this also clickbait?
correct
Unless the roots are filtering the air isn’t the carbon doing most of the filtering? Why not just have a plants and a separate carbon filter
House plants would work very well in a passive House I assume
yeah given they get tons of light and have some good internal air flow
Thx a lot for this video
He looks like Harry Potter. But I love this channel and Harry Potter.
lol
Try moss next
How legit is the information that we cannot use them to clear the air in the bedroom lets say?
you can load your room full of plants if you want because they are nice to look at but they wont do any noticeable changes to your air quality
@@TechplantChannel I've heard some people say the opposite that 12+ spider plants on shelves are enough to clear a little office and it smells differently in there.
great job
Thanks!
Great Video! How can I get a Techplant Tshirt?
when i find a way to get them cheap so ppl who buy em dont get scammed lol
Great video, I enjoyed watching it.
Thanks for watching!
Lo So you encompassed your test with V.O.C. emitting materials even melted V.O.C. glue sticks and say plants cant clean the air well enough, ok, gotcha....Had you actually tried and used decent controls but your findings are bunk considering the materials you used.
Nice video man!
Thanks for watching!
It looks nice to me
Thanks!
@@TechplantChannel you're welcome
Plants do clean the air. It depends on the space you live in. Also you need a lot of different air cleaning plants for it to work. It’s not going to work if you have two plants in a big house.
i agree they do clean the air, but houses exchange air so fast that they cant keep up
@@TechplantChannel I think that's what she meant by "it depends on the space you live in" if you don't have an air conditioner (there are still places that don't crazy i know) then it will help clean your air. More than nothing.
I am gonna have 5 plants with plenty of light and nutrients for a bed room... ... making use of that stupid aircon unit and the fan, which I am using masks to filter as much dusts and such as possible.
You gotta see how much those re-usable masks collected over merely one day.
good to know
Thanks for watching!
I see the orchids seem to be liking the coconut pots - awesome!
Yeah!! One flowered! Although the one coconut that I sanded has large cracks forming but so fat the structural integrity is holding up.
That's what I thought too... ... this is NOT gonna work for a room when my maid or boy needs to open the door again and again.
I am gonna use the stupid aircon which is bringing in air pollution from outside such as unfilter-able smoke and haze and such... ... it will cool the air, then I am designing a much BIGGER bout of air... ... oxygen, more plants... ... larger dust filter and use that old fan... ... a huge fan to pump. Gosh... ...
I will need polymer layers... ... such as book wrappers or something else create the air containing portion, get a new fan, to move the dust and chemicals in the air unit while the greenhouse will release oxygen plus cleaning up as much chemicals before pressures will bring the best air out to the room. That means I need to slow down the air... ... let the densities create its layer of particles and let the best layer through, something like creating an atmosphere... ...
So... since oxygen is usally lighter... ... ... ... the opening must be at the top, while as many plants at the bottom... ... and the rest of the filtration will be done by connecting to the fan, to be pumped into the room. Bloody neighborhood with an MP and government which can't work, and smokers and pollutions ain't stopping by itself... ... No choice. A large scale air unit will be needed, as if you are in a space ship.
If I am into dealing with a professional unit with proper equipment and funding... ... it will be much easier, and I will do it another way.
I have locked on every component I need. Now... ... I only need to buy the barriers and design the actual setup structure. Hee hee hee hee... ... ...
I also need ions from the plants... ... This set up ain't good enough.
That is possible if you have a jungle inside your room.
true lol
I will trate this with darlingtonia californica, because is a plant that likes to have fresh root.
Ive never grow that species, but it might dry them out too fast. i would be careful! but goodluck! I grow a lot of sundews maybe putting an airstone in there would be good.
@@TechplantChannel You should try that species is very exotic because it is called "cobra lilly" is one of the best carnivorous plants
Another brilliant video on the myths of plants as purifiers debunked with science.
Thanks again! They CAN work but it would take sealed environments and lots and lots of plants and soil. en.wikipedia.org/wiki/Biosphere_2 this was a really interesting experiment. this thing took tons of engineers to create and in the beginning they had huge issues, especially with the old version!
i must have missed the experiment where it was debunked in this video
i never believed this household air purifying claim either
Yeah after reading the study it looks like the soil and micro organisms along with the activated carbon do a lot of purifying too. but it takes a long time to do so. They tested these in small sealed containers where it could re circulate the same air over and over again over 24 hours. In a house where you arent sucking air through the soil they are almost useless for purifying the air.
I don understand
exquisite content
thanks for being such a long time watcher. I always look forward to seeing your comments. I hope your plants are all doing well!
this was awesome
Thanks for watching!
haha you crazy. I LIKE THAT
lol

Can you imagine being both attractive AND smart?
this is a compliment right?
Techplant
Oops, should’ve used “this” instead of “both.” 🤧 But, yes.
@@lucifersguts hehe thank youuu
Too complicated.
Agreed its a lot of hoopla for very little air filtration!
Useless
