Review on Trettitre Portable Purifier Sanitizer Eliminate by Carri Taylor

They're the best, even for their small size. We bought two for our bedroom, plugged them in and left them overnight. No noticeable noise disturbed our sleep. In fact, we both slept soundly. When we left the bedroom the next morning we could smell a difference in the air. The air in the bedroom was definitely fresher than the rest of the house. To be honest, we were very surprised. Virtually silent and very efficient product. We plan to take them with us on trips as well, for use in hotel rooms. They weigh next to nothing, have no lithium batteries and run on USB Plus instead of a 110 outlet. Most hotels have bedside lamps with an open USB port so that would be perfect! We liked them so much we bought 2 more portable air purifiers along with replacement filters - although the filters last many, many hours of use! Excellent purchase!
