I bought 2 of these humidifiers and absolutely love them.  I had not used an evaporative humidifier before but I’m finding I definitely prefer this to the customary mist humidifier. I would definitely recommend this product to 
a friend.
The only suggestion I would make, is to include a separate noticeable note card in the box making sure people realize they need to save the float retainer on top of the filter, as the replacement filters do not come with this piece.
