I can tell when they are wearing out. Within a day or 2 of plugging the new ones in…especially in the bedroom, I feel like my breathing is better at night. Sinuses seem better, rooms feel cleaner. I live in FL now.
Wasn’t used to the humidity, all the rain, even to the point of mildew now and then in the bedroom closet. I buy the cheaper one, 3 at a time, and feel like they work well for about 2 years.
Pros and Cons:
Bottom Line: Yes, I would recommend this to a friend
