SmartVentilation’s “opened-up” Type III filter compared with a typical homemade “hogshair” filter installed by other radon mitigators in south Florida
Type III filters were designed by Wayne Dean of SmartVentilation. They are MERV 14-15, the equivalent of an N95 filter for the air entering you home through a Daisy Ductless Ventilator, and they exceed the USEPA recommendation of MERV 13 filtration. They are manufactured of premium materials in a respected filter factory. We normally keep 250-600 filters in inventory at all times. You may purchase SVI filters at https://smartairstore.com.
Type III filters remove pollen, mold spores, viruses, bacteria, PM2.5, soot, red tide and blue-green algae toxins, smoke.
Filter Service Life? 18-24 months under normal conditions.
Service life of homemade fresh air filters is 60-90 days at which point they become loaded with dirt and block airflow rendering the radon system ineffective. As a matter of practice, Homemade Filters are almost never serviced, exposing occupants to original radon risk. VERY NOT GOOD
PM2.5 is very Bad News.
Recent research indicates that increasing environmental levels of PM2.5 are reflected in similar increases in the incidence of Alzheimer’s.
Analysis of brain tissue of Alzheimer’s patients indicates higher levels of toxic heavy metal and radioactive material accumulations carried as hitchhikers by PM2.5 particles
To collect PM2.5 particles on an air filter seems preferable to allowing them to accumulate in brain, heart and bone marrow tissue
