Key Takeaways

  • Radon is a dangerous radioactive gas that can cause myriad of diseases and is responsible for several lung cancer related deaths in the U.S.
  • Air purifiers with HEPA filters can help with radon gas but cannot completely eliminate it. They are recommended to be used in conjunction with specialized radon mitigation systems.
  • You can hire a professional service or get a radon testing kit to detect if your home is contaminated with this dangerous gas.

I come across a lot of people who have no idea of what radon gas is. Many people first hear about radon when they’re buying a new home and a potential house tests positive for radon.

Radon gas is odorless and colorless, and exposure to it can lead to serious health issues. It’s the second leading cause of lung cancer, right behind cigarettes. So if you haven’t tested your home for radon, now’s the time.

The only surefire way to remove radon is with a radon mitigation system. However, an air purifier may help filter radon and improve air quality.

Keep reading to find out how air purifiers can help reduce the risks of radon gas exposure.

Do Air Purifiers Help With Radon Gas?

While air purifiers can improve your air quality, they are not explicitly designed to remove radon gas. They are not explicitly designed to combat radon, but certain air purifiers can help filter out radon particles from the air.

Radon is a radioactive gas that can enter your home from the soil beneath it. Breathing it in over time can be deadly, and according to the EPA, radon causes 21,000 lung cancer deaths each year.

When I’m dealing with radon, I always turn to air purifiers with a HEPA filter. These filters are highly effective at capturing small particles, including radon gas. My purifier also has an activated carbon filter that’s useful in reducing radon levels.

Just know that using an air purifier alone will likely not be enough to significantly reduce radon levels in your home. The most effective way to reduce radon levels is with a radon mitigation system. Mitigation systems vent the gas out of your home.

So, while air purifiers can help filter out radon particles and improve air quality, they should not be relied upon as the sole method of radon gas reduction. It’s essential to consider a professional radon mitigation system for the most complete protection against the risks of radon gas exposure.

Can Radon Be Filtered Out Of Air?

It’s possible for radon to be filtered out of the air. While certain air purifiers can help reduce the amount of radon gas in the air, they should not be the only method of radon gas reduction. The most effective way to reduce radon gas levels is to use a combination of techniques, including radon mitigation systems and air purifiers.

Several studies have tested a range of air purifiers to determine their effectiveness in reducing radon levels. They mostly find that air purifiers with activated carbon and HEPA filters, effectively reduce radon levels. The study also noted that air purifiers should not be used as the sole method of radon mitigation.

HEPA filters and activated carbon air filters are indeed effective in reducing radon exposure. HEPA filters can capture small particles, including radon gas. Activated carbon filters can help reduce the levels of volatile organic compounds (VOCs), which can also contribute to poor indoor air quality.

Does A HEPA Filter Remove Radon?

While HEPA filters do not filter radon gas directly, they can capture radon decay products attached to other air particles. HEPA filters capture physical particles like dust and pollen, and if they’re contaminated with radon, they can be removed by a HEPA filter

Again, do not rely on them as the sole method of radon mitigation. When my house came back with elevated radon levels, I bought air purifiers and had a mitigation system installed.

Does An Activated Carbon Air Purifier Get Rid Of Radon Gas?

Activated carbon filters can effectively absorb volatile organic compounds, including radon gas. Using activated carbon filters alongside other radon mitigation methods, such as sub-slab suction or ventilation systems, is recommended to ensure that radon gas is effectively removed from the home.

While some air purifier models may advertise themselves as effective for radon, ensuring that they have been independently tested and certified is essential. For example, Instant HEPA Air Purifier and Bissell MYair Air Purifier include activated carbon filters, which can effectively reduce radon levels in the air.

However, using other radon reduction methods alongside these air purifiers is still vital for maximum effectiveness. You should also regularly test for radon levels in your home and take appropriate measures to reduce exposure.

How To Test Radon At Home?

To ensure your home does not have elevated levels of radon, you should test for radon gas regularly. You can contact a professional near you to run a test or purchase a test kit from your local hardware store and check for radon gas yourself.

A professional radon mitigation company will bring the necessary tools to test for radon in your home. If you choose to test for radon levels in your home yourself, you can buy a short-term or long-term at-home test.

When my home is tested for radon, I always order long-term tests for more accurate results.

As their name suggests, long-term tests will give you results over an extended period. These tests use activated charcoal or electret ion detectors to measure radon levels and they remain in your home for at least 90 days to measure long-term radon levels.

Whichever method you choose, regular testing for radon gas in your home is essential to ensure your safety and the safety of your loved ones.

Will Dyson Air Purifiers Remove Radon?

Dyson is a common household name for a variety of appliances. Products made by this company include vacuums, heaters, and air purifiers. They are popular because Dyson is a reliable brand with highly-rated products.

The company’s vacuums are extremely effective at removing tiny particles from areas and being extremely quiet. Likewise, their purifiers are also effective and quiet.

Most Dyson air purifiers contain carbon granules making them effective at reducing radon gas levels. Additionally, they include HEPA filters which may capture radon-contaminated particles. However, they are not recommended as the sole means for reducing radon in a home.

People Also Ask (FAQs)

Is it OK to live in a house with radon?

It is not okay to live in a house with radon. Radon is the second leading cause of lung cancer when you’re exposed to radon over long periods.

Does opening windows reduce radon?

Opening windows can help reduce radon. The airflow from an open window can improve ventilation and air circulation. However, this is not a permanent solution and should be used with other mitigation methods.

Does radon travel through walls?

Radon can travel through cracks in walls. Windows, showerheads, and sump pumps are other common entries for radon.

How quickly can radon affect you?

It can take years for you to realize radon has affected you. Symptoms may not appear for years or even decades, but the risk of developing lung cancer increases with higher levels and prolonged exposure to radon gas.


Radon gas is a severe health hazard and the second leading cause of lung cancer if left unaddressed. As an HVAC professional, I have my home tested for radon a couple of times a year, and I use air purifiers to help keep radon at bay.

Air purifiers with a HEPA filter and an activated carbon filter are the most effective air purifiers for reducing radon gas exposure. Still, they should be used with other mitigation methods.

If you’re afraid your home might have elevated levels of radon, get your home tested and consult with professionals to ensure the safety of your indoor air.
