I first bought the Alen Paralda air purifier for my bedroom, my allergies went away immediately.
I started moving it around the house and liking how it all felt, wanted to get a larger unit, so I called and spoke to a very knowledgeable person who advised me on the right one to get The Breath Smart 75i , just love both air purifier, I noticed less dusting and health is so much better, I also have a dog, and that is all good. I would highly recommend Alen products .
