Radon Fans Sizing Guide
Find a radon fan based on your home’s construction. This will determine where you install the unit outside or in your garage, attic, or basement. You can also install it under the foundation if your property is under construction.
You can either evaluate your location yourself using a DIY test kit or you can hire a mitigation contractor. If you find that you have a high radon level, you will want to install a radon mitigation system to vent the radon out of your house.
Low & Medium Power SSD Fans
Typically installed in new constructions, these types of fans are noiseless and durable. Using three to four-inch piping can accelerate exhaustion, but since they use little power, they can also save on electricity.
High Flow SSD Fans
Usually retrofitted into a property, this type of fan will prevent leakage and work under the foundation where the porous sub-slab layer exists. This fan uses four to six-inch piping exhausts, but six to ten inches are better for industrial applications.
Suction SSD Fans
Perfect for areas that have not-so-porous sub-slab materials, this type of fan has three-inch piping in several penetrations to efficiently pull out enough air.
Most people prefer that their radon mitigation fans do not make any noticeable sound. Typical wear and tear can lead to buzzing later on as bearings lose their lubrication. Otherwise, this type of unit should be pretty quiet.
What the entire system is made of is a large consideration. If you don’t have a durable fan or pipes, you won’t have your system for long.
How do I find out if I have radon gas in my home?
Typically, you will see symptoms and signs in your family if there is radon gas present, especially in your kids or the elderly. These signs can include loss of appetite, bronchitis, persistent cough, hoarseness, wheezing, and mild chest pain.
If there is prolonged radon exposure, it can eventually cause death with symptoms that go undetected.
If you feel your family is being affected by radon, you can purchase either an electronic radon gas detector or a manual radon gas test kit.
Both are affordable and convenient in helping to determine your initial radon levels. Then, if you feel that there is radon in your immediate home surroundings or your neighborhood, call a professional to help you with the situation.
What happens when I detect a leakage?
If you detect leaks, you can either fix them yourself or call for professional help. After you are aware of your home’s radon levels, you should install a radon mitigation fan system, which is a basic fan and pipe system that will remove radon particles from your house venting them out of your property.
Where do you install the radon mitigation system?
It will be installed in either the attic or basement of your home as they are the two main areas to be affected.
How long does installation take?
Typically, it will take about three to five hours to install the fan system.
Will you hear vibrations or sound?
At some level, the unit will make noise, but there will be no significant vibrations and only a negligible amount of noise.
Can you remove radon in other ways?
Typically, a radon mitigation process is used with sub-slab-depressurization. Other corrective measures can be used like sealing cracks, but they should be used along with the installation of the mitigation fan system.
How much does a mitigation system cost?
The cost can vary depending on the product or services you choose. Also, you need to consider if there is a pre-installed passive system as well as how complex your property is, which can decrease or increase the overall cost. On average, a system can run between $800 and $2000.
What is a safe radon level?
There are no safe radon levels when it comes to your family’s health. The standard acceptable number is 4 pCi/L with anything higher considered very dangerous.
There is a built-in passive radon removal system already in my home, is that enough?
Unfortunately, you will still need to install an active radon removal system in order to vent out the radon from the pipes and lower the gas levels. A passive system is not successful on its own.
Every home will have different requirements for the best radon fans. Depending on the location, you may need a different radon fan than someone else. Make sure you know your current radon level and your home requirements to make sure that you buy the right radon mitigation fan for your needs.
