I have had an air purifier in my hair salons for the last 12 years, and am especially pleased with your pureAir 3000 that has been in my salon for almost 2 years! Yours is much quieter, and seems to work much better than my old one, and it looks nicer, too. By having your air purifier in my salon, I know that not only am I much more protected from the normal pollution in indoor environments, but the added pollution of all the things that happen in the air in hair salons. I now have confidence that anyone that walks into my hair salon that is coughing or sneezing will most likely not pass it on to me. (There are exceptions, but I’ve only experienced those twice in the last 2 years!) I’ve actually had several of my return clients tell me that they just seem to breathe easier when they come in to get their hair done! It’s nice to know that I don’t have to breathe all those dead skin cells, pieces of hair, chemicals from perms or color, hair sprays, other people’s sick stuff and anything else that is in the hair salon air that would harm my health, anymore! And I’m also protecting my customers’ health. I loved the fresh air so much I got one for our home, and we got one for each of our children for their homes to protect them, too! I now sleep soundly (my husband says I don’t snore much at all now), probably because I don’t have to sleep with my mouth open now that I can breathe through my nose.
