In the late 1980’s, research indicated that plants had the capability to remove volatile organic compounds (VOC) from indoor air.  The findings were based upon chamber studies involving injection of a pollutant into a small, sealed chamber and following the pollutant decay, with and without plants present.  The results were striking with removal rates up to 90% in 24 hr.  Other studies examining this effect followed.  Today, even a casual search of the internet will find many articles extolling the benefits of using plants as indoor air cleaners.  However, there has been little critical analysis of the application of plants to actual indoor environments and only a few field studies have been conducted.  A critical review of results of both laboratory chamber studies and field studies leads to the conclusion that indoor plants have little, if any, benefit for removing indoor air of VOC in residential and commercial buildings.  Finally, recommendations for improving future studies are presented.

I live in Shanghai (PM2.5 goes over 300), and this has made a huge difference in my quality of life. This air purifier is quiet and small, but very effective. I used to wake up with a sore throat every morning due to the pollution here, but since getting this I’ve had no such problems. It’s even helped keep my skin looking good, since bad air can take a toll even with a good routine.

I usually turn the purifier on 3 (loud) when I first get home and keep it there for about 10-20 minutes before turning it to Auto. On bad air days, I keep it on 2 (pretty quiet). I turn it on 1 (very quiet) before going to bed, since the shifts of Auto can be slightly disruptive if you’re a light sleeper. Overall, it’s made a huge difference in my sore throats and skin. China’s pollution isn’t so scary if you have something like this to keep you a little bit safer.” Bought this while in a deployed environment.

It performs as advertised, it has kept our room clean from dust for a long while now and has made the room very pleasant to be in with no odors! That’s the best part!

But really not a big deal for me personally.” The AP-1512HH is a mighty air cleaning unit that is designed for large spaces.
