Air-Filtering Houseplants – All you need to know!

The original Nasa Guide to air-filtering houseplants was written way back in 1989! This is something we stumbled upon recently since NASA announced that was providing free open access to all its published research late last year – “Public access to NASA-funded research data now is just a click away, with the launch of a new agency public access portal. The creation of the NASA-Funded Research Results portal on reflects the agency’s ongoing commitment to providing broad public access to science data.”

This infographic provides a great overview of the report entitled “INTERIOR LANDSCAPE PLANTS FOR INDOOR AIR POLLUTION ABATEMENT” by B.C. Wolverton, Ph.D.


The report covers chapters from “A Promising, Economical Solution to Indoor Air Pollution” to  “Gas Chromatograph-Mass Selective Detector Analysis for Trace Metabolites” Concluding with a full Microbiological Analysis and a chapter on Activated Carbon-Houseplant Air Filter System! So as that’s quite a mouthful we thought it would be much better presented in this infographic summarising the findings!


So What’s In Our Air?

Like most chemicals, the adverse health effects you may encounter depend on several factors, including the amount to which you are exposed, the way you are exposed, the duration of exposure and the form of the chemical. Below are common symptoms associated with each toxic agent.


Symptoms associated with short term exposure include excitement, dizziness, headache, nausea and vomiting followed by drowsiness and coma.


Symptoms associated with short term exposure include irritation to nose, mouth and throat, and in severe cases, swelling of the larynx and lungs.


Symptoms associated with short term exposure include irritation to eyes, drowsiness, dizziness, headache, increase in heart rate, headaches, confusion and in some cases can result in unconsciousness.


Symptoms associated with short term exposure include irritation to mouth and throat, dizziness, headache, confusion, heart problems, liver and kidney damage and coma.


Symptoms associated with short term exposure include eye irritation, coughing, sore throat.

For optimal air-filtering, NASA recommends placing at least one houseplant per 100 square feet of home or office space.
