Review on Optimus U 30012 Humidifier Replacement U 33100 by Richard Ahmar

This is one of the best humidifiers I've ever had and I think that's because of those wick filters. The filter stays wet even when not in use. I sometimes turn it over because of mineral buildup from our water. The price is reasonable for two packs and I usually use both during the winter months. When it starts to dry up I order my two packs from Revain and so far have had no problems with them missing. I highly recommend the humidifier that comes with these filters - it's easy to clean, humidifies the air with no white dust/vapor and does what it's supposed to do.
