These are the plants I use in my house, although I built my home as a non-toxic one so they are useful for whatever else shows up.
Spider plants are among the easiest houseplants to grow, and remove formaldehyde, benzene, carbon monoxide an xylene, a solvent. Spider plants are OK to have around your pets.
Peace lily plants are relatively small compared to many of the plants on this list, but they still pack some major air-cleaning abilities. Easy to grow, and remove ammonia, benzene, formaldehyde, and trichloroethylene. They are toxic to pets so please don’t keep them in a spot where the animals can chew on them.
Boston Ferns prefer to clean the air from a cool location with high humidity so make sure in the winter you add a humidifier to your room. They’re relatively easy to grow, but they do need to stay moist. They also remove formaldehyde and xylene and are fine to have around pets.
In addition to being easy to care for, Aloe ‘s leaves contain a clear liquid full of vitamins, enzymes, amino acids, and other compounds that have wound-healing, antibacterial, and anti-inflammatory properties, but don’t eat the plant… it must be processed correctly or is toxic to the body. It also removes formaldehyde. Do not leave where you pet can chomp on it as they may develop diarrhea and if it gets severe you may have to take them to the vet.
