Product review (3 stars): Filters do fit.... But beware of foul smell!
I have the V3600 cold humidifier. The replacement filters do fit.... after some force is applied and squeezing of the filter as you push it in. Not fitting perfect is a fact of life, I can get past. But what I dislike about this replacement product is the smell the filters give off. I read reviews about the the foul smell but decided to try it anyway. After two weeks of daily use and rinsing of filter daily before each use I noticed an odd smell in my room. I looked high and low thinking someone left dirty laundry or the like out for too long (smelt like a high school locker room). I stood in front of the humidifier and smelt the cool air coming out of it. Bingo! source of the smell. I'm confused on why this product gives off this unpleasant smell because the original filter lasted 4 months until it was too dirty to reuse, and IT NEVER SMELLED only discolored... I have used two of the three filters purchased within the past month. At the rate of replacing filters due to smell I would be better off buying a new humidifier ( I original bought it for ~30 USD).
