Product review (3 stars): Gets Expensive
I buy these filters all the time. My son needs the humidifier, and we have had good success with it. The filters start to get expensive month to month, because their lifespan is short, and dragging that span any longer could become a health risk. With that said, I bought the product, and like it so I do need the filters. Someone should make a washable/reusable filter for this unit. Aside from that, Amazon should offer a quantity discount, that would help those who really need the filters on a regular basis, to lower some expenses. 3 out of 5 stars because they work. If they were $2-$3 a piece which is what they should be, they'd be a 5.
