This homeowner contacted True Air Technologies for a difficult to mitigate home. His apartment was measuring high levels of radon and the HOA would not allow him to put a depressurization system on the outside of his home. Because he didn’t own the apartments above him, an internal system was not an option. Using a phased approach, True Air Technologies decided to install a BreatheEZ Air Cleaner to decrease the radon decay products (the dangerous by products of radon gas). TAT installed the filter in less than an hour and then conducted a WL test to measure the rdp’s. The filter reduced the rdp’s well below the US EPA action level of 0.02 WL providing cleaner safer air.
