5 Best Radon Mitigation Fan 2024: Reviews and Buying Guide

Radon Mitigation Fans are the most sought solution for reducing RADON contamination from your home. They are found to reduce RADON levels up to 75% from your home.

RADON is a colourless, odourless, harmful gas that cannot be traced or detected. It silently penetrates in your house through water, soil and rocks beneath your home surface.

WHO reports tell that RADON is the 2nd most cause of lung cancer worldwide. Not only this, but it is also responsible for 15% fatalities caused due to lung cancer.

What adds more to your worry is, you will only come to feel RADON contamination in your home environment once you start feeling chest pain, difficulty breathing, nausea, weight loss etc. Not to forget these are symptoms of the onset of lung cancer.

So, before it’s too late you must start thinking of securing your family from this RADON contamination inside your home. Don’t worry we will help you with this task.

Here in this article, you will find TOP5 Radon Mitigation Fans to protect the health of your family. Choose from easy to install fans that not only reduce RADON but also add fresh air from the atmosphere to your home.

The brands we have mentioned here are all affordable in price and give you the quality-efficient performance to save your electricity bill also. Yes, these fans do produce a bit of noise while working, but with increasing technology, every effort is being made to reduce this.

You must go through following three points which are most important to consider while you buy your Radon Mitigation Fan 

  • Airflow Rating: This aspect of your fan tells how much air your fan can exhaust per minute. It is told by Cubic Flow per Minute (CFM). As this rating increases, your fan takes less time to reduce radon levels. So, we will advise you to buy a fan that gives you high CFM in less power consumption.
  • Warranty: Maintenance of your radon fan is a highly expensive procedure. So, if you are buying a low-cost fan which does not have a warranty period then drop the plan of buying that fan. It will give you lots of trouble in future. You will end up spending more money on maintenance than you saved while buying that.
  • Noise: Noise is something which every machine carries with itself. So is the case with RADON FANS. But the noise production majorly depends upon the design of your fan. As you will spend more money, you will get a better-designed fan which produces low or little noises which are sustainable. Hence our advice for you will be to buy low noise fan irrespective of its cost.

Wondering are these only points to consider? Well definitely not, you just need to go through the “Buying Guide” we have created for you and find the other aspects that are required to be considered.

Now we are all ready to introduce you the TOP5 Radon fan brands we have segregated for you after doing lots of research and reading user reviews. They are as follows

How To Select The Best Radon Mitigation Fan

Here we present you with very important factors to keep in mind before you buy your Radon Mitigation Fan. Read through following times and find what you should seek in your purchase. After going through this buying guide you will not end up wasting your money on a wrong fan, that does not suit your purpose.

1. Type Of Mitigation Fans

There are four different types of radon fans available in the market. Each of them has the same purpose which is to reduce Radon but in different ways. Let’s look at them one by one.

  • Room Pressurization: These fans direct the contaminated air sucked from your room to the basement of your home. Hence you don’t need to keep climb up your roof to install the air venting system on your roof.
  • Power SSD Fans: They are useful to install if your new house construction is going on. They exhaust the air out of your home. Their fans use low power and generally, they are noise-free. You can use them with 3 or 4inches PVC pipes. They are of two types, low powered and high-powered fans.
  • High Flow SSD Fans: These fans are fitted outside of your home and connected with a pipe coming beneath your slab or the concrete floor. In this way, they suck the gas from the ground and direct it to the atmosphere without letting them entering your home.The fans we have mentioned here fall in this category only. You can connect them with 4-6 inches pipes if used for home, or with 6-10inches pipe if using for industrial usage.
  • Suction SSD Fans: They are similar to high flow ssd fans but good for the areas that aren’t so porous. You can use them along with 3-inch piping to get an efficient reduction in radon levels.

2. Durability

Radon fan is something which you don’t want to buy on regular basis. Because of the price as well as the trouble it gives during installation. Thus, the fan you are buying should be durable.

If it is getting overheated then it will get damaged, if it is not waterproof then moisture may damage the motor, if the walls of the pipe or not sealed then radon gas may leak. If it is prone to corrosion then the surface of the motor casing will start breaking off that will make it prone to water entering it.

All the above factors are the points that show your fan is durable or not. So before buying your fan ensure the above points are not present in your fan. You should also check the manufacturer’s website for more information.

3. Energy Efficiency

Radon fan that you are buying must be energy efficient as it will add to the electricity bill of your house. A decent power fan has the power rating of 30-70Watt.

You will be happy to know that all the fans we have mentioned here are less than 70watts. So, you can buy any of them without worrying about your electricity bill.

But buying a low wattage fan will be of no use if it does not work efficiently. So you should also check the work efficiency of your fan along with its power rating.

4. Airflow Rating

Airflow rating is measured in Cubic flow per minute. It tells how efficiently your fan exhausts radon out of your area. You should go for the fan that has high cfm, as it will take less time to reduce radon levels from your home. However, with increasing cfm cost of your fan also increases.

5. Noise

Radon fans like any other fans have a motor which runs them. So, it is obvious that they will also produce noises while running. But as technology is advancing, modern fans are now having efficient motors that do not produce much noise.

So, while buying your fan doesn’t go on its low price as low-price fans have compromised design and produce a lot of noises, which is not a good thing if you are installing the fan for indoor purpose.

And we are happy to tell you that all the brands we have mentioned here are not having high noises in their performance. You can buy them with any problem with high noises.

6. Warranty

Radon fans are very expensive. Thus, if they get damaged because of some unavoidable reasons then getting their maintenance done could cost you a huge amount of money.

So, you should always seek a brand which gives you a decent warranty period. This warranty should not be of one or two years. But a minimum of 5 years. You will be happy to know that all the brands we have mentioned here provide you with the warranty of at least 5years.

Still, if you want more warranty then you can go for TJERNLUND RADIN FAN as it gives you 10yeasr of warranty.
