From EZ Breathe
We are a 2nd generation family owned and operated business that has been working in homes with basements and crawl spaces for over 35 years. We have been waterproofing and sealing about 500 foundations a month during that time as the largest Waterproofing contractor in the Midwest with 15 locations servicing 8 states. 20 years ago we would seal a foundation and recommend a dehumidifier to address the additional water vapor (humidity in the air) inherently found in below grade environments, such as basements and crawlspaces. Back then, dehumidifiers were the industry standard to help with this problem. However, many of our customers were looking to us as the “foundation expert”, asking… What else do you have? Thus, EZ Breathe was born

Our EZ breathe is everything they said it would be. Installation tech was very good, did a great job. The system is working great and we can tell the difference in the air in our home.
Outstanding air exchange unit....installation, including some demo and reclamation of a single assignment device, was less than 3 hours....started noticing a difference nearly immediately as it pertained to "basement odor". After 24 hours now, the difference in air "feel" and smell is superb...think of this as a "water softener", for your indoor air....not a scientific term, but it this unit has a similar effect for air that a softener has with water, to me...Highly recommended.
The EZ Breathe has really been great! I did the installation myself, it was simple, the instructions were clear, and the kit included everything I needed. We tested for Radon after a month using the EZ Breathe and the level was drastically reduced. We are very satisfied with this system.
