Buying Guide: How to Pick the Right Air Purifier for Radon

Air Flow Rate

The airflow rate measures how efficient the air purifier is. It measures the number of times contaminated air passes through the air purifier. It is usually estimated in ACH(air changes per hour). The higher the rating, the more capable your air purifier is when getting rid of radon gas.

The Air Flow rate is usually affected by the room size. The bigger the room, the lower the ACH rating. The manufacturers of air purifiers usually indicate these ratings. Ensure you check these ratings before buying one.


Air purifiers come with the costs of running and maintaining them. These costs are in addition to power consumption as some units are inefficient and need a lot of electricity. An air cleaner requires filters to be regularly replaced for perfect functioning. Some purifiers come with permanent filters, while others have filters that can be washed. The filters must be replaced following the manufacturer’s guidelines.

The latest air purifiers come with filter replacement indicators. They notify you when the filters are old and need to be replaced. Some filters can be expensive, while others can be hard to find. Consider these factors before buying an air purifier for radon gas.

Room Size Coverage

Air purifiers come with different room size requirements. You should know the measurements of your room before buying an air purifier. They usually have limits on the maximum area which they can clean. The room size capacity is usually indicated in square feet. Some models work perfectly for bigger rooms, while others work well for small spaces like dorm rooms.

An air purifier placed in a room bigger than the required size will not work perfectly. It may consume a lot of power but do very little to get rid of radon gas. The manufacturer of the air purifier usually indicates the room coverage. Consider the ratings before buying one.

Type of Filters

Air purifiers come with different types of filters. The filters are effective for getting rid of harmful Pollutants, but not all of them can be used in radon mitigation systems. HEPA filters are the best filters for removing radon gas from your home. For them to work well, they should be used together with activated carbon filters. They suck in the polluted air, pass it through the different filters, and release clean air.

The pre-filters trap larger particles before they get to the HEPA filter. The radon gas is filtered out in the activated carbon filter. Some air purifiers use UV light. They help improve the air filtration process.

Noise Levels

Air purifiers have fans that produce noise. Some Purifiers are loud and can make you uncomfortable, especially when sleeping. The noise level is measured in decibels. The higher the measurements, the louder the air purifier will be. Ensure you buy an air purifier with noise levels that range between 40-50 decibels. Getting air purifiers with lower ratings will be much better.

Some models produce white noise to help you sleep. They might come at an extra cost but are worth the price. You can also buy purifiers that use HEPA silent technology. They produce very little noise; you can even have conversations with them running.

Smart Features

Some air purifier models come with smart features. They include WiFi connectivity and air quality sensors. Such air purifiers might be expensive but can automatically detect radon gas in your home and other pollutants. Here is how such features can make it easier to use a purifier;

  • Timer – you can use the timer and set the air cleaner to be turned on and off at specific times. It can be turned on at certain times during the day or night.
  • WIFI Connectivity – air purifiers that can connect to the WiFi come with apps that allow you to control them from your phone. You can turn them on and off from anywhere. It also allows you to use voice commands.
  • Air Quality Sensors – the quality sensors automatically detect a rise in radon levels in your home. The air purifier will then be turned on to deal with the pollution.


Air purifiers are expensive devices. Consider your budget before buying one. Some models that come with smart features can be very costly. Buying an expensive air cleaner does not always guarantee performance. Sometimes the high prices are because of design rather than performance.

Power Consumption 

Your air purifier might run throughout the day or night. The device consumes power and energy. Some energy-certified air purifiers use less energy. Before buying an air purifier, consider the power it consumes by looking at the ratings. More power consumption will result in high running costs.

CADR Rating

The CADR rating refers to the clean air delivery rate. The manufacturers of the air purifier indicate it. These ratings show the air purifier’s ability to remove different pollutants. The pollutants indicated include smoke, dust, mold spores, radioactive gas, and harmful chemicals. The higher the rating, the better the air cleaner. This rating is also affected by the room size.

Most air purifiers have fan speeds that can be increased or decreased. Adjusting these fan speeds affects the CADR ratings. The ratings increase at higher fan speeds when the air purifier has many filters. You cannot increase the CADR ratings of an air cleaner using an ionization process.


The longer the warranty period of an air cleaner, the more valuable it will be when you buy it. A warranty of up to 2 years is a good bargain and will save you money Incase of any repairs. Some air purifier models come with lifetime warranties. This could be an added advantage for anyone who plans to buy one.

What is Radon Gas

Radon gas is a naturally occurring radioactive gas. It is produced when uranium is broken down in soil and water. The gas is colorless and does not have any taste. You cannot smell the gas or any other toxic gases that are a radon decay product. 

When radon decays, toxic chemicals enter walls, floors, and ventilation systems. Radon gas is the leading cause of lung cancer worldwide for people who don’t smoke. Manu lung cancer deaths in the world are caused by exposure to radon.

Radon is a radioactive gas that can damage your lungs and tissues when you breathe it in. Radon gas decays and releases harmful particles that affect the cells in your lungs. This further increases the risk of lung cancer.

Radon gas is very dangerous because you cannot easily detect it. This is because it has no smell or color. When people are exposed to radon gas for long periods, they risk getting lung cancer.

Radon levels vary depending on the area. They can sometimes be found in buildings or rocks. Soil contains uranium which can decay and produce harmful gas. Testing is the only way to determine the radon levels in your home or building. 

After testing, you can reduce your exposure to radon gas by installing a radon mitigation system. The radon mitigation system absorbs all the radon from the air, leaving your home with clean air. The system uses a ventilation system to capture radon gas from the room and release it to outdoor air. You can use other ways, like keeping your windows open and using fans to reduce exposure to radon gas.

Why is Radon So Dangerous

Radon is dangerous because it decays and produces radioactive particles. The dust gets trapped in the lungs and might affect the cell’s linings. It damages the cells and increases the risk of getting lung Cancer.

Does Opening Windows Reduce Radon Gas

Opening windows does not remove radon gas in the long term. It’s a temporary solution to the problem. Once you close the windows, the radon levels will still rise. This is because the sources of the radon gas might still be in the house, and they keep releasing the toxic chemicals.

How to Test for Radon in Your Home

There are two ways you can test for radon in your home. You can either use short-term test kits or long-term test kits.

A short-term test kit is a helpful tool for determining the radon levels in your home. You can quickly get the results at an affordable cost. The EPA recommends quick test kits for initial tests of your home. The tests can be completed within two days. These test kits are the fastest way to know your home’s radon levels.

Long-term tests give you more reliable results. They are not affected by the fluctuation of radon levels. Some days show higher radon levels than others. Long-term tests offer you the average radon levels and determine if there is a risk of radon exposure.

Do HEPA Filters Remove Radon 

Yes, having an air cleaner with HEPA filters can help remove radon gas. These filters can get rid of dust particles, mold spores, and other harmful pollutants. The HEPA filters and an activated carbon filter should be used to remove radon. An air cleaner can remove radon gas from the room, but they are not as effective as opening windows.

Our Testing Process

We use radioactive particles to test each air purifier’s effectiveness wholly and quickly, removing them from the air. This test is based on the industry-recognized Clean Air Delivery Rate (CADR) test for air purifiers. Although it’s a valuable tool to test products, remember that your house’s performance may differ because of room sizes, shapes, and radon levels.

To maximize its probability of working successfully, each device is tested at its higher fan speed setting.

When the radon gas has been evenly distributed around the test chamber, the testers determine how quickly it naturally precipitates or decomposes from the air. The process is then repeated at lower fan speeds.
