Question: Is it necessary to "clean" this unit with white vinegar or bleach if you use a bacteriostatic cleaning solution when you refill the unit?
Document: The humidfier is nice but the filters are junk. Can't clean them even with water to flush out the build up. Plan on buying a couple filters a month if you intend to clean your unit every couple days as needed I started adding a tsp of bleach to the holding tank every other time when I refil it and that seems to keep the bottom half clean so you don't have to take it apart every few days.. Everytime you move the filter to clean the humidifier it get more and more fragile.
Seems to be doing a good job, only used it for 2 weeks. Runs quite on low speed, my preferred setting. Easy removable fill tank, and easy to refill and reattach to unit. Would recommend.
This humidifier works well in its first season. Easy to clean (washes up in the sink or in the dishwasher) and replacement filters are easy to find. I have a water softener and so didn't want all the extra minerals in the air from a misting type unit and like that this type is not mold producing if kept clean.
We have had this for about 4 years and are very happy with its ability to keep 1200 SF at &#62;40% relative humidity throughout the winter (in the Northeast US).Pros: Reliable and effectiveCons: A little noisy at the medium setting that we use (noticeable but not annoying) - very loud on high setting.Difficult to clean around the filter-holding protrusionsFact of life:  For us the filters last about a month, so count on buying a $20 filter monthly
A lot of money for a simply molded plastic case with no moving mechanical parts except a cheap fan that is noisy and vibrates. Too noisy to be in the same room. Sure, the fan can perhaps be balanced by the user, but why should that be necessary? Should be a $40 unit including the controls---  worth more only with a quality fan.
The residual improvement was felt throughout the house. A noticeable improvement in sinus pressure and static electricity was very evident right away. Be sure to use a Bacteriostatic Water Treatment to reduce the chance a bacteria and mold in the humidifier. I used BestAir brand and have had no problems.
These work great and quiet. I fill it up and it works all night and they are not hard to clean.
So far I am pretty satisfied with this humidifier. It does the job and is easy to clean. The only thing I don't like is that the water tank is not clear.
sure helps keep my home in better humidity  air is easier ti breathe and sleep is easier easy to clean and operate
I am so glad I have the Essick Air Humidifier. It has helped my breathing so much. It was easy to set up and clean. It works in the whole house. I have used the Air Humidifier for one month and I am breathing much better.
Answer: I used mine extensive last year for about 4 months and it needed minor cleaning monthly and again before putting it away.  Even with the bacteriostatic solution it got a bit slimy were the water sits but none of the nasty mineral crystals like other types of humidifiers.  Warm soap and water, or a quick run in the dishwasher is fine and you don't need to cycle  vinegar through it like a coffee pot, very easy.  I was surprised at the length of use I got out of the filters and how cheap it is to use generic filters cut to the proper length.
