I highly recommend the Austin Air purifiers. I did a 10 year analysis of this purifier compared to a competitor's product I was considering. Both are highly recommended by professionals. This product won out for the best value with replacement filter costs. I am 100% pleased with simplicity, quietness, ease of use and effectiveness. I plugged it in straight out of the box, no other set up required. I know the air quality in my home is now staying clean and pure.
I'm pleased with the auatin unit and also the company for there guick dilivery thank you allergy reliefe
