What a difference Air Scrubber Plus has made! We can breathe SO MUCH EASIER with no sneezing fits. It allows both of us to sleep better without all that nasal stuffiness that often kept us awake. As an extra bonus, it automatically clears odors from the air – odors like our cat box, smokers, cooking, etc. We love the Air Scrubber Plus and all it does and happily recommend it to anyone and everyone.
