## Customer Reviews

### ⭐⭐⭐⭐⭐ Radon levels dropped instantly!
*by E***N on September 20, 2023*

Easy to install! The instructions were good, even showing the PVC fittings that were needed to construct the mitigation system, all of which were available at my local home improvement store. We have seen the levels of radon go down significantly since we installed this. We would highly recommend this product! Well worth the money spent to keep our family safe!

### ⭐⭐⭐⭐⭐ Would give this a 10+ star rating if possible
*by D***E on January 19, 2020*

This fan is amazing. Here in Alaska with our frequent earthquakes big and small, radon is a problem. My husband and his friend did the installwithout incident in 2 days time. From the moment he dug the hole in our crawlspace and inserted the pipe, our radon level began to rapidly decrease. Once the fan was installed and the pipe vented out 3’ above the roofline, our radon reading went from over 15 to below 1 in less than 12 hours. I cannot say enough about this quiet, hard-work fan (my husband isn’t bad either, lol). Its ease of use and quality craftsmanship saved my family from lung cancer. Highly recommend.*** The entire set up including fan, piping, joints and a cap cost us $600. We saved more than half the price of calling someone in to install.** we installed fan in our garage as Alaska gets subzero temperatures of down to -30 during our long arctic winters.

### ⭐⭐⭐⭐⭐ Easy to install. So quiet!
*by T***S on July 16, 2021*

Install was easy. Instructions included. Very quiet! Works like a dream.
