How many house plants are needed to improve the air quality in the home and which plants are best to choose?

Question

By how many I also mean area (or acreage!) of greenery.

I used to have a lot of different plants, but most of them have died either through neglect, cats, children or mostly I think, the central heating, which I never had until I moved to my current home. I need to counteract the effects of the gas boiler as well as TV, computer and the like.

Spider plants are the only ones to thrive but I think that's because I move them to the bathroom or landing for a holiday. I would like more variety.

Answer 1

i think the plain green house plants like ferns are good for what you want em for... an aloe is good to have too...you just break the leaf and you can use the inner gel for facials, as lotion, an antibiotic, for zits... countless things

Answer 2
