Best 2022 Christmas gift! This product has made such a difference in our home. We use the purifier everyday - my whole family can tell the difference in our air quality. We like the unit so much that we purchased a 2nd unit for our 
Master bedroom. Air feels so much better and our master furniture doesn’t accumulate dust as quickly.  We also have the mini units in 2 of our bathrooms. I have also had great success with customer service. Great product - love my gift.
