Review on Wein Vortex VI-3500 Ionic Room Air Purifier by Erica Houlf

Bought for a friend who has a constant sore throat and has had the flu for two winters! She and her husband always had breathing problems and allergies. Nobody has had a sore throat or an allergy problem since their birthday in September! Hopefully this will help ward off viruses and bacteria in the coming winter months! Very satisfied so far! I am thinking of buying it for those who have health problems. So far, so good! Thank you!
