Ficus (Ficus Elastica) – This plant is low-maintenance and doesn’t need much sunlight. It’s very good at clearing formaldehyde from the air. But be careful if you have pets or small children — its leaves can be toxic.

English Ivy (Hedera Helix) – A must-have plant. In just 6 hours, it can remove around 58% of airborne feces particles and 60% of harmful toxins.

Spider Plant (Chlorophytum Comosum) – This one can grow even in low light and is excellent at soaking up toxins like carbon monoxide, formaldehyde, fuel fumes, and even polystyrene. One plant can purify the air in a space as big as 200 square meters.

Sansevieria (Sansevieria Trifasciata ‘Laurentii’) – Very tough and easy to care for. It works well in darker rooms and is perfect for bedrooms because it gives off oxygen at night.

Peace Lily (Spathiphyllum ‘Mauna Loa’) – A beautiful plant that removes formaldehyde, trichloroethylene, and other toxins from the air.

NASA suggests having 15–18 of these types of plants in a 500 m² area. That means for every 80 m², you should have 3 or 4 plants. And don’t forget to place one in your bedroom — you spend hours sleeping there, and clean air makes a big difference.
