- Do houseplants clean the air? Have you heard of the NASA Clean Air Study? In this video, I walk you through this study & more to determine whether or not plants really do purify our air...

They’re definitely good for your mental health. It probably has similar affects to that study showing spending time in nature every week helping with anxiety and depression if you surround yourself with foliage in your house
i love to start my day off nerdy with coffee and plants
Becca: like any good student I did my homework
Me watching this video instead of doing my homework: 👁👄👁
the amount of air that plants "clean" - is negligible compared to the amount of VOC's created - in a typical home -by measuring surface area alone
(i.e. there is a lot more "stuff" in your house that generates VOC's than stuff that cleans it)
you would have to fill your house with so many houseplants that you can't even see the walls or furniture - in order to get a noticeable effect
Also, even such an effect would be irrelevant compared to the effect of simply opening a window and allowing natural air circulation......
Space stations, colonies, and spaceships cannot "open a window"- which is why plants capacity for purifying the air (and generating oxygen) is critical for those environments, but almost completely irrelevant for the typical earth-bound home....
Yeeeaapp. It’s funny how this “air purification” thing has been taken over as a marketing tactic or latched onto by those of the more “crunchy” crowd as it’s a gimmick.
This reminds me of the 'rainforests are the lungs of our planet' type sayings when 75% of the oxygen is produced by algae.
Ahhh!! Yes!
super interesting! it’s weird how “air purifying” has become such a marketing tactic for certain plants without the marketers/sellers taking into account the complexities of those studies. but i guess picking and choosing by people with vested interests has always been done with scientific studies
As a former NASA scientist, I'm glad that you made this video.
Google scholar & Researchgate are also good sources of information.
Ooh!!! So glad to hear that and to know that you approve! Haha ✅
Very important subject.
Even though they do not clean that much air, we can minimise the amount of voc by ourselves. For example, use water, vinager, citric acid, etc. To clean surfaces. Also buying used furnitures lessens the vocs. As well as not using the aerosols. :) Especially families with kids here in Finland keep away of any of the products that leads to increase in voc.
There has been also increased interest in drifting stuff and not using synthetic paint indoors (old recipes for making paint are being used).
You totally did a play on words without noticing:D when you said it’s up in the air lol.
Omg I did! 😂
Love these fact-based videos! It feels like there's a lot of plant common knowledge that doesn't have much scientific support. There's a lot of practical knowledge you can gain by experimenting with growing, but fundamentally understanding what is going on and why is so fascinating.
Yes definitely I agree!! Lots of common knowledge/knowledge passed-down but hard to find cold hard facts! Haha.
I love this!! Thank you for doing the research for us 🥰
Absolutely!! ❤️
Talk about a comeback! What a topic to discuss 🤯👏🏼
Great video! I wasn’t expecting the soil to play such a key role in removing the voc’s. I guess it makes sense though! So interesting 👍
Right? Glad I haven't switched to leca 😂
This is so interesting!!! Thank you for sharing this information!
So interesting. Thanks for doing the grunt work for us Becca!
Gladly!! ☺️
Really interesting!
Yes I've researched so much about this myself! Very interested in watching this video! 😆
Thank you for this video!
☺️
@@BeccaDeLaPlants I love that you try to inform yourself and us on the foundations of houseplants.
Great video as always from you!!! Thanks for breaking this down. Just like for fish tanks and any other organic environments, the success of the system depends what happens at the microscopic level. Again thanks and I hope there are more videos like this to come.
Super interesting. Now having to think about college my mom suggested a career involving plants, like botany, and this video made me more inclined to a plant related career.
Plant related careers are the best!! Not for me because I don’t do science 😂 but love people who enter into them!
Verry interesting video!
I also read the studies, thanks for sharing them.
😌
Very informative!❤️
☺️
So interesting, and makes sense. Microorganisms come in all shapes and sizes. Some need oxygen to survive, some don't. Some are toxic, some are beneficial. Microbiology is seriously so cool 😊
You really had your teacher hat for this one. Thanks for explaining the purpose and findings of this over-referenced study. I think the only conclusion to be drawn is that we just simply need more plants.
I say also taking good care of the plants so the soil they are in absorb those air toxins well.
:) Becca, I gotta tell ya...I am a bit geeked out! NASA has been a formidable teacher of me for many things....the launches, the space station, I have been to the Kennedy Space Center at Cape Canaveral, it completely blew my mind & I needed to know more, but I was already a Mommy...I thought I could do only one thing! :) Yea, right...that lasted for maybe a month! 2 Thumbs up on keeping your air clean.
Thanks for taking the time to research this Becca- very informative. My question is what about plants that are in LECA , I presume as they are not in soil with soil microbes the effect of VOC removal would be even less?
Ooh that’s a great question!!! I’d say so yes 🧐🧐 I wonder if there are microbes involved with leca at all? Hmm..
My modest one-bedroom apartment is one of those types of homes where as the resident I need to keep it mostly sealed from the outside environment because bugs will enter through the holes in my heater/AC to escape outside extreme heat or cold and so I cover it with an insulation protectant curtain. Some mornings I manage to remember opening a living room sliding door and/or bedroom window for air circulation, but given the fact that I live in CA and climate change has made our fire seasons far worse, circulating air from outside has become far more risky. These indoor air purifying houseplants are a good idea for residential circumstances like mine.
Oh yeah I can see that for sure!! Plants are great for situations like this ☺️
Nice video :)
Thanks! ☺️
The short answer would be no, I guess. I mean, they do clean the air in those conditions set in that initial test, which are completely unlike our homes, offices etc. The air inside our homes gets renewed far quicker than the speed of this mechanism, plus the sources of VOC emit those constantly, not in one set dose and then you're left with clean air. There's one key critical review showing that plants cannot be used as such in our home as they specified the actual cleaning rate in all studies that claimed a positive result, forming the conclusion that you'd have to have an truly impossible amount of plants to show any measurable effect, let alone significant. I've told all this to people who sell plants to see their reaction and they were like "ok then". Mysteriously enough, they kept claiming the same benefits to their customers, who would have thought. I also like it when people try to spin this a bit "well ok, but plants do improve your mood and that has to affect your mental health and overall health as a result". Well, yeah, I'm taking the wild guess that this is possible if you actually love plants. If you think they are devices for cleaning your home, I'm venturing into a "no" again.
Hehe...RUclips cut to commercial right after you said “...done gotten rid of.” 🤦🏻♀️ I thought you just quit the video after saying that. 😜
Hahahah😂😭 youtube was giving you a way out lol
So what I’m hearing from this is, the more plants the more likely it cleans the air 😂
😂😂 in essence, yes hahaha
The more plants, the more their potting soil cleans the air. 🤗
Your link to the NASA study is broken.
the only thing that my plants do for my air is make it more humid. my “plant room” sits at about 60 with no humidifier, where the rest of my house sits at about 45
Oh wow!! That’s incredible
I heard or read somewhere that you would have to have over 100 plants just for you to get some sort of purifying results! lol
Yes!!! Hahaha
Only thing i see - leaves collect dust. Soil can be a source of fungi spores. I dont feel that plants make my air fresher. I grow them for decorative purposes.
