Query: A worthwile product for the price

The product is fine. I no longer wake up congested from the dry air in my apartment. It is a hassle to have to refill the tank and to wet the filter every night. I wouldn't say that it is quiet but it doesn't keep me up at night. I think the benefits outweigh the negatives. No major sinus ailments this winter season so far.
