Breathe Easier: How Houseplants Help Reduce Pollution and Improve Indoor Air Quality

At Denver Plant Club, we believe that adding houseplants to your home isn’t just about aesthetics — it’s about wellness. Plants can do more than just look cute in a sunny window. They can actually help you breathe better. Yep, your pothos might just be your new favorite air filter.

With indoor air pollution becoming more of a concern, especially in tightly sealed homes during Colorado’s colder months, it’s worth asking: Can houseplants help reduce pollution and improve air quality indoors? The answer is a resounding yes — but let’s dig into how.

Plants: Nature’s Air Filters

Back in the late '80s, NASA conducted a study on how plants could be used to clean the air in space stations. Their research showed that certain houseplants are especially effective at filtering out common indoor pollutants like formaldehyde, benzene, and trichloroethylene — substances that can sneak in via everyday items like carpets, paints, furniture, and cleaning products.

These air-purifying plants don’t just sit pretty. They absorb airborne toxins through their leaves and roots and convert them into harmless byproducts. In short: they’re working hard for you and your lungs.

And here’s where it gets even better: plants also increase humidity by releasing moisture during transpiration, which can be a lifesaver in dry climates like ours in Colorado.

Top 3 Houseplants That Improve Air Quality

While nearly all plants offer some air-cleaning benefits, a few go above and beyond. Here are three of our favorite houseplants that improve air quality and help reduce pollution in your home — and yes, we carry all of these beauties at Denver Plant Club.

1. Snake Plant (Sansevieria trifasciata)

Also lovingly known as “Mother-in-Law’s Tongue,” the Snake Plant is a low-maintenance powerhouse. It’s one of the few houseplants that continues to release oxygen at night, making it perfect for bedrooms.

What it filters: Formaldehyde, benzene, xylene, and tolueneWhy we love it: It’s nearly indestructible, thrives on neglect, and looks sleek in any modern space.

2. Spider Plant (Chlorophytum comosum)

This cheerful plant is a champion air-cleaner and a great choice for new plant parents or anyone with a bright window.

What it filters: Carbon monoxide, formaldehyde, and other VOCs (volatile organic compounds)Why we love it: It’s pet-friendly, grows fast, and shoots out adorable “baby” plants that you can propagate or share.

3. Peace Lily (Spathiphyllum)

The Peace Lily not only reduces pollution but also adds a touch of elegance with its deep green leaves and occasional white blooms.

What it filters: Ammonia, benzene, formaldehyde, and trichloroethyleneWhy we love it: It’s as beautiful as it is functional. Just keep it away from pets, as it’s toxic if ingested.

Do You Need a Jungle to See Results?

Not at all. While NASA’s study suggested that you’d need a plant every 100 square feet to make a major impact (hello, urban jungle dreams), you don’t need to transform your home into a rainforest overnight. Even a few well-placed houseplants can help reduce pollution and freshen up the air in the spaces where you spend the most time — like your bedroom, office, or kitchen.

At Denver Plant Club, we’re all about helping you find the right plants for your space, light levels, and lifestyle. Whether you’re a seasoned collector or a first-timer, we’ll guide you toward plants that will thrive in your environment and support your wellness goals.

Bonus Tips to Maximize Your Plant Power

• Rotate your plants occasionally to ensure all sides get light.

• Dust the leaves so they can breathe and photosynthesize more effectively.

• Use well-draining soil to prevent root rot and keep your plants healthy.

• Avoid overwatering, especially in winter months — soggy roots are sad roots.

• Add a few plant buddies to boost both the air-cleaning effect and the visual impact.
