Pollution not only increases risk of respiratory illnesses, heart disease, learning disabilities, and even cancer, but can also accelerates aging. According to the Environmental Protection Agency (EPA), “studies of human exposure to air pollutants by EPA indicate that indoor levels of pollutants may be 2 to 5 times—and occasionally more than 100 times—higher than outdoor pollutant levels.”

They add that indoor air pollutants have been ranked among the top five environmental risks to public health.

We can reduce indoor pollution by vacuuming and dusting frequently, opening a window as much as we can, and investing in a quality air filter. But there’s another way to make indoor breathing easier while adding a nice atmosphere to our indoor spaces. Buy more houseplants! Any greenery helps, but there are certain plants that clean the air better than the rest.

For maximum efficiency, use 15 to 18 plants in a house that’s 1800 to 2000 square feet.

Think one plant for every 100 square feet.

You don’t have to buy that many at first. Invest in a few, and then propagate additional ones off the original. (my favorite way to get new plants!)
