Rated 4 out of 5 by Sunnbeam Love Mine
I ordered the red, which is a deep, muted shade that is versatile. I have been using my humidifer every night since I received it except for the first week - needed time to set it up -- and one week when I was out of distilled water. Is quiet, works great. My skin, eyes and nose are not dried out when I wake up and I snore less. My only concern - I have to figure out if the lights can be turned off without shutting off the unit. Right now I turn the lights away from me. They do not disturb my sleep.
Rated 5 out of 5 by CLinCT White dust gone
I am just about at the 30 day mark using these. Since I put these in my three humidifiers the white dust problem is virtually gone. I have hard, well water and the dust was almost a daily chore to clean, now I don't see it and when I do in tiny places it is after about three weeks.
Rated 4 out of 5 by SewCrazy So far they seem to be working
I'm using my first cartridge that came w/humidifier. Decided to alternate using tap and distilled water. Used distilled for 1st month; then tap w/cartridge over the last 3 weeks.
Really haven't seen any white dust residue with either method. Am considering buying another color humidifier!
Rated 1 out of 5 by Verified Reviewer Did nothing to cut down or elimate 'white dust'
The directions say that if you have hard water or use a water softener it is recommended you use distilled water. I'm no chemist, but doesn't distilled water have all the minerals already removed? If that is the case, why do you need something to demineralize?
I had less dust by filling the humidifier with water I ran through the refrigerator filter first before I received the cartridges. Adding the cartridges did nothing to lessen that dust.
I'll be sending them back today. Also the next pick up by Purple Heart will be getting both ultra sonic humidifiers. I'm going back to my 'old fashioned' filtered humidifiers.
