I think the only awesome description of this product is the "filterfree," however it looks like it needs a filter. I have 3 children so I have my share of humidifier experiences. The filterfree was why I purchase this thinking I would be saving money, but in the end I ended up having to purchase a different one. Maintenance is horrible with this product because there are areas that you cannot reach to clean. It's pretty noisy at 2nd and 3rd speed level. It's pretty large so takes up a bit of room. I think it works well for about 90 days and after that it goes downhill and most likely be out of return/exchange policy. It's a pretty poor device expensive product that you might want to pass and move on.
