air purifying plants

Plants not only bring life and nature into your home but they also improve your health by purifying the air you breathe. In fact, according to NASA clean air study, there are at least 18 air-purifying and air-filtering plants.

Don't just use air-filtering plans in the living room - some of these plants are great for the bathroom too!

Air-purifying plants: how does it work?

Indoor plants that clean the air and remove toxins are known as purifying or filtering plans. They work by absorbing toxic gasses through their leaves and roots. Microorganisms in the soil also help neutralize pollutants such as VOCs (volatile organic compounds).

How many plants that clean the air are needed in a room?

NASA suggests that at least 2 plants are required for every 100 square feet. However, the bigger the plant’s leaves, the quicker it can purify the air.

For the most efficient air-purifying indoor plants, try fern and ivy which have great surface area coverage.
