The National Aeronautics and Space Administration (NASA) has been studying the effects of plants on air quality for about 20 years and their research confirms: common houseplants are natural air purifiers.

While the original research was aimed at finding ways to purify the air for extended stays in orbiting space stations, the findings are important for us on Earth as well. The following plants are documented as being especially good at improving indoor air quality:

1. Aloe Vera

It's one of the best ways to help treat sunburn, but aloe vera will also help rid your home of formaldehyde.

2. Areca Palm

Just like aloe vera, elephant ear philodendron will cut traces of formaldehyde from your space.

Also known as the weeping fig, the ficus plant will cut formaldehyde from your house, but there is a catch. The common houseplant has also been shown to trigger allergies for sensitive people.
