This is the BEST humidifier on the market for hard water in my opinion. Daily/Weekly cleaning is very minimal and its pretty quiet. I live in a decent-sized studio apartment and it keeps the humidity steady. When I first turned it on, I turned it to high because the humidity was 18%. After about an hour and a half, it was up to 52%, so I switched it to low. I can keep it set to low all day and night and the humidity will stay around 42-45%, it's wonderful. The difference was tremendously noticeable after just the first night. I woke up with a clear nose, I slept with my mouth closed, my eyes weren't itchy and red I have severe dry eyes and skin, and my head didn't ache. Definitely get the humidity monitor with digital display, as well as the antimicrobial cleaning cartridge, and change the filter every 30 days. I have had this for a month and there is no slime in the base, nor is there the stale/moldy smell that was typical in humidifiers I had before. The tank and base are completely separate from the machine, so the chance of mold and mildew building up seems next to impossible to be able to occur. I don't have a dishwasher, so every week I wipe the base and tank with vinegar and it works just fine. I pour a decent amount of vinegar into the tank and shake it vigorously without the cleaning cartridge and after rinsing both the tank and base thoroughly, there is never a lingering smell of vinegar. Do NOT waste your time researching humidifiers, this is hands down the best one out there for hard water! I am not certain if its meant for filtered or distilled water, but if it is, get it!

This product keeps the air in my 20x20 bedroom just right and I barely notice it running on low and moderate setting. It is audible at the highest setting but it is a soothing whir. Best of all, no more dry, cracking skin or bloody noses in the morning! I wouldn't say that it is completely going to eliminate the white powdery residue in your house unless you use filtered or distilled water but it makes a huge difference compared to many other comparable units.

This unit is very easy to maintain, but I noticed the filter is tinted light brown on the fringes after 3 days of use with distilled water in a well maintained, clean home. I will need to research that, thus the 4 stars.

Works well. I have it in my bedroom and it really helps me to sleep better and not wake up several times to drink water. The only thing I would like to see is more output at lower speeds. The quietest speed, the one they say is for sleeping, does not put out enough humidity to help. It has to be on the number 2 speed at least to work well. I have learned to sleep with the extra noise because the 2nd speed is the lowest you can go and still get a good output.

Happy with my purchase so far. The unit is huge, but sleek looking. Quiet on the low and medium settings, cannot see the mist coming out. Got the Protec cleaning cartridge and threw one in the bucket. Looking forward to having this going in the bedroom while sleeping in the dry Colorado winter.

I switched from a vapor humidifier to this one where you do not see the moisture, and I have to say, it is a bit tricky at first to know if it is working. I can tell you, though, that once the filter started to get old, I did notice the air getting drier and there was less water being used up in the tank. I do recommend this item - also it is nice to not have any moisture damage from normal humidifiers. Just a word of wisdom - be weary when buying replacement filters. There are a lot of fakes out there that are nowhere as good as the genuine Honeywell filters!

Q: I hear the fan turning, but I don't see any mist. Is my humidifier operating properly?
A: Dry air is pulled through the system and a fan disperses invisible, moisture balanced air. There is no "mist" emitted. When operating normally you will feel only cool air coming from the unit. Monitor the water level in your Tank/Base. If you notice a decrease in the Water Tank over 24 hours then the unit is operating normally.

Q: My unit has been running for several hours. I hear the fan spinning, but I do not notice the water level in the tank decreasing.
A: First, check the filter to ensure it is wet. If the pad appears dry, remove it from the Base and gently rinse under cool water. Reposition wet filter in the Base. You may also want to note the current moisture level in your home. If the humidity level is over 60% the unit will not put out much moisture as your air is already saturated. Also verify the upper enclosure and water tank are properly seated.

Q: My filter has turned light brown and rust colored. Do I need a new filter?
A: Probably not. Since your filter has been made with Protec antimicrobial, the change in color indicates only a mineral deposit. Soak filter in a sink full of cool water to help break up deposits. The discoloration may remain but will not affect the humidifier's performance.

Q: My humidifier doesn't appear to be as clean as when I first purchased and/or I'm smelling an unpleasant odor. What should I do?
A: You probably need to replace your Protec Antimicrobial Cartridge. This cartridge helps your humidifier stay cleaner, longer and helps freshen the mist. If you have been using your humidifier regularly for over 30 days replace the Protec cartridge and follow the cleaning instructions.
