Indoor plants as air filters

Indoor plants not only look great, they can also help clear your house of common environmental pollutants.

Using indoor plants to clear the air

There’s nothing quite like the scent of forest air – the real thing, not an air freshener :).

While some of that lovely earthy scent is due to decomposition, the trees and plants of a forest are constantly circulating oxygen and carbon dioxide, unlike in the midst of a concrete jungle when the air we breathe can get somewhat stale or downright poisonous.

Our homes aren’t an oasis from our toxic modern environment either. The inside of our houses can have very poor air quality due to fumes from cigarette smoke, furnishings, paint and other items. Some items can give off these fumes for many years – that smell of fresh paint and new carpets isn’t just potentially harmful just while you can detect it.

The airborne chemical cocktail inside our home often includes:

benzene – used in oils, paints, plastic, rubber
trichloroethylene (TCE) – paints, lacquers, varnishes and adhesives
formaldehyde – foam, clothing, particle board, carpets.

All of the above have been shown to be potent environmental pollutants and likely carcinogens in humans.

New homes can be particularly bad for formaldehyde – it might be at many times the generally considered safe level for quite some time. Office air can also be saturated by a fog of toxins due to the type of furnishings and floor coverings often used on commercial premises.

Keeping indoor plants not only adds a nice green touch to our homes; some indoor plant species have proven to be effective filters for pollutants such as the above and carbon monoxide (an element of car exhaust).

A while back, I came across a couple of very interesting studies by NASA carried out in the late 80’s and early 90’s that included information on the plants NASA found useful as indoor air filters to combat these chemicals.

Beneficial plants include (scientific name followed by common) :

Aloe vera
Aglaonema Modestum – Chinese Evergreen
Chamaedorea Seifritzii – Bamboo Palm
Chlorophytum elatum – Green Spider Plant
Chrysanthemum morifolium – Pot Mum/Florists’ Chrysanthemum
Dracaena Janet Craig – Janet Craig
Dracaena Marginata – Marginata
Dracaena Massangeana – Mass cane/Corn Plant
Dracaena Warneckii – Warneckii
Gerbera Jamesonii – Gerbera Daisy/African daisy
Hedera Helix – English Ivy/Common Ivy
Philodendron Domesticum – Elephant Ear Philodendron
Philodendron Oxycardium – Heart Leaf Philodendron
Philodendron Selloum – Lacy Tree Philodendron
Sansevieria Laurentii – Mother in law’s tongue
Scindapsus aureus – Golden Pothos
Spathiphyllum Mauna Loa – Peace Lily/Mauna Loa

Some of the above are more effective than others at filtering particular chemicals, so if you’d like to learn more about the NASA research, here’s the study:

  1. Innovative watering pot you use for your basil above. I’ve been struggling to find ways to allow my plants to slowly water themselves when I’m away traveling (I have too many plants and too little sink space to keep them standing in water) and the inverted plastic bottle pot seems ideal.

  2. Great green post! I’ve used Peace Lilies for this reason as I gather they cover a broad range of toxins in the home (inside air is worse than outside) apart from the fact that I like them so much! Also I have orchids and aloe which can be kept in the bedroom to help clear the air and use topically, of course.

  3. I was looking for this kind of information for years… thanks. One idea.. whether we can keep any of these plants in an automobile??

  4. Great blog, covering some very important topics, and an interesting post. It’s good to see I can use a potted chrysanthemum and add a bit of colour as well as clean air. Thank you for liking my blog.
