12 Of The Best Plants For Cleaner Indoor Air

The right to clean air is a fundamental right. Yet we rarely ever get to breathe clean air, especially in cities. Since Americans spend most of their time indoors, healthy air quality should be a top priority.

Indoor plants are not only beautiful to look at, many of them can clean the air in your home too. Yes! All plants are natural air filters (thank you mother nature!), but some are better at removing toxins than others.

Can indoor plants really purify your home?

People lined their windowsills with greenery in increasing numbers after NASA released a series of studies dating back to the late ’80s, stating that indoor plants could purify the air.

Sadly, it seems there was a little wishful thinking going on back then. Researchers now say you’d need 680 plants in a 1,500-square-foot home for the foliage to truly go to battle against toxins.

But indoor plants have other air-boosting and health benefits that you don’t have to create a wall-to-wall jungle to enjoy. Even a modest amount of foliage might enhance indoor air quality. So why not add a few easy-care plants to your living space?

Health benefits of air-purifying indoor plants

Although it would take filling your home or office with ridiculously massive amounts of foliage to impact VOC levels, indoor plants can still improve your air quality.

Indoor plants can

  • reduce irritation to eyes, ears, nose and throat
  • prevent or ease coughing and congestion
  • lower your stress
  • boost your attention capacity

Purifying indoor plants reduce levels of CO2 and increase relative humidity. In other words, they help get rid of stale air and act as a natural humidifier, which can prevent or ease irritation to your eyes, nose, throat, and even lungs.

Beyond improving air quality, foliage just makes people feel better. Interacting with your indoor plants can reduce stress, for example.

That doesn’t mean you have to chat up your aloe vera – unless you want to. We’d never judge. Repotting, pruning, or watering your air-purifying indoor plants will do the trick.

Similarly, just by being in the room with you, that ficus can help you maintain focus when you’re slogging through a tough task like a school paper or a report for work.

3. BAMBOO PALM

All palms are great air purifiers. The surface area of the leaves of palms extracts more carbon dioxide from the air as you breathe at night and returns oxygen to the room that they are in.

Since the bamboo palm, or reed palm, prefers part sun or shade, it makes a great houseplant with the added benefit of aiding in the removal of harmful elements such as benzene and formaldehyde.

For the greatest success, place it in a spot where it gets mild morning or afternoon sun. It also has normal watering requirements, just don’t overdo it.

4. SPIDER PLANT

Rubber plants are tolerant of neglect and so can be grown easily by those with little experience with plants. They should be allowed to dry out between watering.

Why does indoor air quality matter?

Whether sleeping, binging Netflix, or working in an office, we spend about 90 percent of our time indoors, according to the Environmental Protection Agency. And that time spent inside exposes us to indoor air pollution.

Causes of indoor air pollution

  • furnishings
  • carpet
  • upholstery
  • dry-cleaned clothing
  • paint
  • synthetic building materials
  • cleaning products
  • pesticides
  • bacteria
  • mold
  • outdoor pollution that enters

You probably don’t think of your coffee table as emitting gasses, but if it’s made of particleboard, it does. The paint on the walls and the upholstery on the furniture are just some of the other items in a home or office that release volatile organic compounds (VOCs), like formaldehyde.

Levels of VOCs are typically two to five times higher inside than outside. We’re all exposed to some amount of indoor air pollution, and it’s likely not causing issues. But, in some cases, when ventilation is bad, or for people who may be highly sensitive, it can make you feel sick. Headaches, nausea, and fatigue are some of the symptoms, and it’s sometimes called “sick building syndrome.”

Add a couple clean air houseplants to the rooms that you use the most, like your bedroom, living room, or office, and you’ll be breathing easier in no time. This list of my top picks for the best indoor plants that clean the air is a great place to start.
