Can Houseplants Help Improve Indoor Air Quality During Wildfire Smoke?

When the skies turn hazy from wildfire smoke, many of us start paying a little more attention to the air inside our homes. 

While houseplants aren't a replacement for an air purifier, they can still play a small role in supporting a healthier-feeling indoor environment, and they make every room look a whole lot better.


So...can houseplants actually clean the air?

What the Research Says

You may have heard that certain houseplants are "air-purifying." That idea comes from a well-known NASA study that found some common houseplants could absorb small amounts of airborne compounds, called volatile organic compounds (VOCs), in controlled laboratory settings.


In a typical home, however, the effect is much smaller than it was in those sealed research chambers. That's why experts still recommend using a quality air purifier or HVAC filter during periods of poor outdoor air quality, especially when wildfire smoke is present.


Think of your houseplants as a beautiful complement to clean indoor air, not a replacement for proper filtration.

More Than Just a Pretty Plant

Even if they aren't doing the heavy lifting when it comes to filtering wildfire smoke, houseplants offer plenty of benefits that make them worth bringing into your home.


They add natural beauty, soften indoor spaces, and create a calming atmosphere. Caring for plants can also become part of a relaxing daily routine, helping you reconnect with nature even when spending more time indoors.


And while researchers continue studying the relationship between plants and indoor environments, one thing is certain: healthy, thriving plants make a home feel more inviting.

Helping Your Houseplants Thrive

Healthy plants are better equipped to do what they naturally do, so a little care goes a long way.

Here are a few simple tips:

  • Place plants in the appropriate light for their variety.
  • Water only when needed—overwatering is one of the most common mistakes.
  • Wipe dust from broad leaves every few weeks to help them absorb sunlight efficiently.
  • Rotate plants occasionally for even growth.
  • Give them room to grow and enjoy them throughout your home.

During Wildfire Smoke Events

When air quality is poor, your first line of defense should always be reducing smoke indoors. Keep windows and doors closed, use a properly sized air purifier or high-quality HVAC filter when possible, and limit activities that create additional indoor smoke or particles.

Once you've taken those steps, adding houseplants is a great way to make your indoor space feel greener, brighter, and more enjoyable while you're spending extra time inside.

Frequently Asked Questions:

Do houseplants really purify the air?

Some houseplants have been shown in laboratory studies to absorb small amounts of airborne compounds called volatile organic compounds (VOCs). In a typical home, however, the effect is much smaller. Houseplants can help create a fresher-feeling indoor environment, but they shouldn't be considered a replacement for proper air filtration.

Can houseplants remove wildfire smoke?

No. Houseplants cannot effectively remove the fine particles found in wildfire smoke. During periods of poor air quality, it's best to keep windows closed and use a quality air purifier or high-efficiency HVAC filter whenever possible.


What are VOCs?

VOCs, or volatile organic compounds, are gases that can be released from everyday household products like paint, cleaning supplies, furniture, flooring, and some adhesives. Research has shown that certain houseplants can absorb small amounts of these compounds under controlled conditions.

Should I buy an air purifier or more houseplants?

Our answer? Both.

An air purifier is your best defense against smoke and airborne particles. Houseplants add natural beauty, greenery, and a calming atmosphere that makes spending time indoors much more enjoyable.

How can I help my houseplants stay healthy?

Healthy plants start with the right care. Give your plants the proper amount of light, avoid overwatering, wipe dust from their leaves every few weeks, and rotate them occasionally for even growth. A healthy plant is always going to look—and perform—its best.
