Appears to be a well designed product
Appears to be a well designed product. We purchased 3 of these for our home as a "test" program for my spouses severe seasonal allergies. Installed them in the master, her office and our dining room. I cannot speak of the total effectiveness other than the home is cleaner, her allergies have lessened within those spaces and I do find dust on top of each of the units as advertised in the information Clarifon provides so we know they are actively working. I believe a longer period is needed / or technical assessment of air quality by instrumentation may speak of its total affect? So far i believe these are operational, have improved the room air quality where installed and may be better than advertised in effective removal of pollen and other contaminants. Thanks
