          Choosing An Air Purifier For Radon Gas: What To Know

          Air purifiers will only release air into our breathing environment after passing through a filter layer.

          As a result, all of the harmful contaminants initially present in the air will be filtered out – including radon.

          And the critical filter that will perform the filtration is called the HEPA filter.

          These filters are preferred when it comes to removing allergens, known as the “Activated Carbon” filter. And is highly effective when dealing with radon (Atomic number 86).

          The essential but crucial items required as a bare minimum for the removal of Radon gases from your home are as follows:

          1. An air purifier that manages the service necessary for the size of your home,
          2. Ensuring that HEPA filters can be easily used with your chosen air purifier,
          3. Ensuring that carbon-activated filters, which contain carbon that works to catch odors and gasses passing through the filter, can also be easily used with your chosen air purifier. These air filters for radon gas are essential for removing radon from the air.

            FAQS About Radon Gas & Air Purifiers

            air purifiers that remove radon gas

            What Is Radon Gas?

            Radon is a sneaky substance. It has no odor, is invisible, and is derived from natural sources such as rocks, soil, and water. Radon is formed in the ground from uranium and can seep into the atmosphere. According to the EPA, radon can also enter our homes and buildings through small cracks or holes and accumulate in the air.

            Although it is not causing alarm, breathing in high radon levels can lead to lung cancer over time. As a result, it is critical to be aware of it and take the necessary precautions. (3.)

            Is Radon Gas Worse In The Summer Or Winter?

            Radon was once believed to be present in higher concentrations during winter the winter season.

            This was due to our homes mostly being ‘sealed’ from the cold outside air, coupled with the addition of burning fuel in the air due to log and gas fires.

            Radon can be present during summer periods as we open our doors and windows to allow cool summer evening breezes to cool our homes.

            Do HEPA Filters Help Remove Radon?

            A HEPA filter has the high-efficiency ability to identify and remove practically all particles from indoor air.

            Radon particles can attach themselves to other airborne particles. Hence HEPA filters are a credible solution to remove radon.

            Is It OK to Live in A House With Radon Present?

            The short answer is ‘Yes,’ but it depends on the radon levels in your home.

            If you smoke and have high radon levels in your house, you greatly risk developing lung cancer.

            Make sure to have a professional test your home, as this is the only efficient way to understand the radon risks to you and your family.

            How do I know if an air purifier is specifically designed to remove radon gas?

            Can an air purifier eliminate radon gas or reduce the levels?

            Is There An Air Purifier That Removes Radon?

            Air purifiers with an activated carbon filter can assist in lowering those levels. And a few brands, such as the Alen BreatheSmart, IQAir GC MultiGas Air Purifier, Okaysou AirMax8L Air Purifier, and Hathaspace Smart True HEPA Air Purifier, are known to be highly effective at removing radon gas.

            It’s important to note that air purifiers should not be your only line of defense against radon gas. Mitigation is the most effective way to reduce levels.

            As a result, it’s always best to employ a two-pronged strategy.

            Can An Air Purifier Eliminate Radon Gas From The Home, Or Will It Only Reduce Levels?

            Air purifiers can help reduce radon gas levels but can’t eliminate them.

            You see, radon is a gas that comes from the ground, and it can sneak into our homes through small cracks or holes in the foundation and build up in the air. (5.)

            So an air purifier can help remove some of it from the air but can’t altogether remove it from home. That’s why it’s essential to have a two-pronged approach, using both air purifiers and other mitigation techniques to reduce the radon levels to safe levels.

            A good tip that you can see if an air purifier is working to reduce radon is to invest in a radon gas monitor. Here is a popular radon detector that is good.

            The most reliable method to effectively deal with radon is understanding your home’s air entry points.

            Either seal these gaps or minimize the time you and your family spend there.

            Air purifiers can help remove radon but become useful when installed with HEPA carbon-activated filters.

            Scientific proof has confirmed that radon is dangerous and can cause lung cancer.

            Financing a suitable air purifier with HEPA filters is more than highly recommended.

            It is recommended that potential consumers confirm their air purification requirements and available budget before investing in an air purifier.
