In the warmer months, it’s tempting to blast the air conditioner in an effort to stay cool. There’s a much cheaper, more environmentally friendly way to keep the temperature down in your house: plants.
You probably have a pot or two around your house for aesthetic purposes. However, you may want to consider adding certain plants that can not only keep the air cool, but also help flush out toxins.
Plants can keep your house cool because they lose water during transpiration, which cools the air around the plants, leaving it purified and fresh.
“A USDA estimate is that proper use of plants could decrease air temperature in an office by as much as 10 degrees,” as Leonard Perry, professor at the University of Vermont, wrote in a 2018 article. “Plus, the moisture released by these plants helps maintain indoor humidity in the human comfort zone of 30 to 60%, and helps prevent materials such as wood from cracking when dried out.”
If you’re looking for a natural, inexpensive way to keep your house cool, consider getting some of these plants, which can help keep temperatures down.

This plant helps to not only cool and humidify the air, but like aloe vera, it is good for cleaning formaldehyde out of the air. In fact, scientists at NASA say the fern is one of the most effective air-purifying plants. It’s an easy (and inexpensive) addition to your home.

5. Snake Plant
The snake plant, also known as mother-in-law’s tongue, is another plant recommended by NASA to help purify the air. The plant gives off oxygen at night, keeping you cool as well as absorbing a large number of toxins in your home. The bonus? They add a bit of charm to your home, especially when paired with a chic plant stand (like this potted version from Lowe’s).
