Does An Air Purifier Help Remove Radon Gas?

by Josh M

Radon gas is a radioactive gas that can lead to health issues such as lung cancer. Without the correct radon reduction system, you may be at risk.

So, does an air purifier help with radon? Read on to find out what air purifier works best and additional steps you can take to reduce radon gas in your home.

Air purifiers are devices that remove toxins, pollutants, and allergens from the air. While they generally improve the overall quality of indoor air, they are often used for specific reasons. For instance, those with certain allergies may use them to alleviate their symptoms.

Common air filters include HEPA filters, UV filters, and electrostatic filters. Each type has pros and cons, along with specific contaminants that they filter the most efficiently. These contaminants include toxic gasses that may enter your home.

Radon gas is a radioactive gas that can enter your home from the soil beneath it. Breathing it over time can be deadly. According to the EPA, about 21,000 people a year die from lung cancer caused by radon gas.

So, Do Air Purifiers Remove Radon? Can Radon Be Filtered Out Of Air?

Certain air purifiers can effectively reduce the amount of radon gas in the air. However, they are best used alongside other methods of air purification, such as suctioning out contaminated air via sub-slab suction.

One study measured the effectiveness of an air purifier in reducing continuous radon gas exposure. The study determined that it was most effective when used alongside other radon mitigation techniques.

Two air purification methods that are effective in reducing radon exposure include HEPA filters and activated carbon air filters.

Does A HEPA Filter Remove Radon?

HEPA filters work by collecting particles like dust or pollen. These physical particles may be contaminated with radon. When unfiltered, they will increase radon exposure in your home.

So while HEPA filters can effectively reduce radon by collecting contaminated particles, they do not filter radon directly. HEPA filters should not be used alone as a long-term solution for radon exposure.

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

Activated carbon filters are primarily used to remove gasses, making them the most effective air filter for radon gas. They contain charcoal which effectively absorbs gasses directly from air and water.

If you are looking for an activated carbon filter air purifier specifically for radon:

  • The Instant HEPA Air Purifier combines a HEPA filter and an activated carbon filter to reduce up to 99% of contaminants.
  • The Bissell MYair Air Purifier has a 3-in-1 filter that includes an activated carbon filter to absorb volatile organic compounds like radon gas in a 100-foot diameter.

While quite effective, activated carbon air filters will not likely absorb 100% of radon in your home. They are best used alongside other air purification methods.

How To Test Radon At Home?

If you are concerned about radon gas entering your home, you can test your indoor air for it. Contact a professional near you to run a test. Or purchase a test from your local hardware store to check for radon gas yourself.

Professionals will bring the necessary tools to test for radon in your home. They may evaluate your home’s indoor air multiple times over three months to know how much radon is entering your home regularly.

You can buy either short-term or long-term at-home tests to test radon levels in your home yourself. These tests generally use activated charcoal or electric ions to measure radon levels. After the time required by the test, you send it to your lab to obtain the results.

Both methods are viable, but a long-term test will give you more accurate results. Short-term tests are convenient if you need to know if radon is present in your house as soon as possible.

Will Dyson Air Purifiers Remove Radon?

Dyson Air Purifier ModelsDyson 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 (FAQ)

Is it OK to live in a house with radon?

No. Living in a house with radon should be avoided. The higher the levels of radon and the longer the exposure, the more likely cancer is to occur.

Does opening windows reduce radon?

Yes, airflow can improve ventilation and air circulation. This will help in removing radon from your home, though this is not a permanent solution.

Does radon travel through walls?

Yes. There are many ways for radon to enter a home. Any cracks or openings in walls are gateways for radon to enter, though it does not stop there. Windows, showerheads, and sump pumps are other common entries for radon.

How quickly can radon affect you?

Radon can cause negative effects in a person as soon as 5 years after consistent exposure. In some cases, it can take up to 25 years for radon poisoning to appear.

Conclusion

Radon is a radioactive gas that can cause cancer if left to build up in your home. Air purifiers can help reduce radon levels in your home, but obtaining one is not the only action that should be taken.

The most effective air purifiers for reducing radon gas exposure are those with activated carbon filters.
