Best Radon Mitigation System

Radon can be a huge problem for anyone, anytime, and anywhere.  Radon gas occurs naturally through the process of uranium decay, and can make its way into your home through cracks in the slab or foundation.  Millions of homes around the world experience elevated radon levels.  Some figures propose that 1 out of 5 homes may have radon reading that would be hazardous to humans. That’s why it is important to have the best radon mitigation system to keep your family safe.

  • 4” duct size is adaptable with 3×4 couplings for 3″ pipe or 4×4 couplings for 4″ pipe.
  • Designed for outdoor or attic use only.

This radon mitigation fan from RadonAway is a small, compact fan unit that features low energy consumption and a minimal noise level.  The internal fan and motor have been carefully sealed and insulated to protect them from outdoor elements, including rain, snow, freeze, and heat.  Post-construction, all seams have been quality sealed to prevent radon leakage and exposure from within the unit. These fans are intended for a long, continuous life in sub-slab radon mitigation solutions.

  • System includes a fan and exterior hood.
  • Engineered to remove harmful radon from your home through hood discharge.
  • Fan and hood both connect via 3” PVC pipe (not included).

The Tjernlund RMS160 has been engineered with the same quality and caution that Tjernlund provides with their gas and oil heater ventilation systems.  This radon gas mitigation system includes a blower unit with 3” connectors, and a side wall hood.  This hood allows for high velocity radon discharge away from the home, eliminating the need for running vertical pipes along the height of the home.  The sealed blower unit houses a safe motor which is very quiet, permanently lubricated, and runs via continuous low wattage electricity.

  • Use 3” or 4” PVC pipe with 3” diameter ducts.
  • Designed for plug in or hard wire operation via electrical box.
  • Rated for indoor or outdoor use.

This unit from RadonAway is designed for flexibility in usage, depending on your space and needs.  It can be mounted via duct pipe or using the integrated flange feature, for more permanent installation.  Its production seams have been carefully sealed in a negative pressure environment to avoid radon leakage, and its internal components are designed to run safely and continuously.  Depending on permeability of the sub-slab material above which it is installed and the overall square footage, it can potentially provide ventilation for two suction points.

Why Should I Install a Radon Mitigation System?

Allowing radon to permeate and accumulate within your home can be very dangerous for your health.  Installing a radon mitigation system ensures that radon is quickly and safely removed from your home and deposited in the open air, where natural air current will provide adequate ventilation and movement.

Homeowners may take several courses of action to reduce radon in their home, including caulking and sealing and cracks or holes in the slab or foundation, and increasing ventilation.  A fan-based radon mitigation provides continuous ventilation, along with an active suction system that prevents radon gas accumulation.

What Features Should I Look for in a Radon Mitigation System?

There are a few things you should keep in mind when choosing a radon mitigation system.  First, double check the foundation type, along with the size of your house.  You’ll need to make sure that the mitigation system you choose is adequate for the entire dwelling.

Additionally, you’ll want to keep cost in mind.  Not only will you need to purchase the fan unit itself, but it must be correctly installed.  You’ll want to seal any potential holes throughout the system, and ensure the base is properly secured in your foundation.  You should also become familiar with the type of foundation you have.  Do you have a full basement, a crawlspace, or a slab-on-grade type foundation?  This will dictation which type of radon mitigation system is best for your home.

Frequently Asked Questions

Should my radon fan run continuously?

Radon levels fluctuate all the time.  A radon fan should run all the time to ensure it is properly suctioning and distributing radon gas, thus preventing it from accumulating in your home.

How do I know if my radon mitigation system is working?

Radon gas is odorless and colorless.  The only way it can be detected is through specifically-designed tests.  Some air quality monitors provide radon detection around the clock.  You may also wish to purchase short-term or long-term radon gas tests, which allow you to evaluate radon levels in your home over time.  These test results will provide readings to let you know if your radon mitigation efforts are adequate. 

My radon fan has become very loud.  What does that mean?

Most modern radon fans and mitigation systems have been designed to create little to no interruption in your daily life.  If your radon fan has changed its sound pattern or volume level recently, this may mean it needs serviced or replaced.  While these units are designed for longer lives than ever before, they unfortunately will not last forever.  Also check your user’s manual for trouble-shooting tips while contacting a professional to inspect your unit.

Can I install a radon mitigation system myself?

Many active suction type radon mitigation systems require drilling through the floor, walls, and/or roof of your home.  This requires speciality tools and know-how.  If you are comfortable with this process, or have the tools and knowledge to do so, a radon mitigation system can be installed easily.

Always refer to the installation instructions for safety.  Additionally, the unit you choose may require professional installation in order to keep the warranty intact. 

Final Thoughts

Regular radon exposure can be fatal.  In fact, it is the second leading cause of lung cancer and lung cancer deaths.  Therefore, if you receive worrisome radon test results, it is best to act immediately with a radon mitigation system to ensure the continued health of you and your family.
