A curated set of the most effective air-purifying houseplants, based on NASA’s Clean Air Study: a snake plant (filters formaldehyde and benzene, thrives in low light — great for bedrooms), a peace lily (removes mold spores and VOCs, blooms indoors), a spider plant (easiest to keep alive, removes carbon monoxide and xylene), and a pothos (fast-growing, tolerates neglect, removes formaldehyde). Each arrives in a breathable nursery pot with a simple care card covering light, water, and placement — no green thumb required.
