I understand that "spider" plants are very good for this

I have plants everywhere. The best place to put plants are in your bedroom, kitchen and living areas. Get the right ones for the right light coming in your windows. Here's a list of low light plants: https://www.sunset.com/garden/flowers-plants/low-light-houseplants#aglaonema

Snake Plant,Garden Mum, Spider Plant, Dracaene, Ficus, Peace Lily, Boston Fern, just to name a few

I get a lot of plants. at Home depot, they are always in good shape here and they label the best for air quality in the home. Hubby has COPD and the bedroom is like a greenhouse. Right now we are propagating over a dozen pothos from a couple of the longest runners we trimmed down.
