I use mine on a regular basis (weekly for 8 months now) to make encapsulated vitamin C. I am careful to pause and cool the cleaner after 9-10 minutes of use. When this unit stops working I will purchase a heavier commercial unit so that I can run for longer periods, but for an inexpensive home cleaner this unit is excellent. It works like a trouper and does an excellent job. I could not be happier with it. It also cleans very well. Great value and well made. Five stars, but be aware that it is not a commercial unit.

I only had it for a few days. It is definitely not very quiet, although the sound is not an annoying sound.

When I let it run for a few hours, the air in the room feels fresher afterwards, so it's definitely helping improve air quality (although I don't have a quantitative way to evaluate it).

It works great when it works There is a known issue with these units, and the dustier the area is that they reside the more often you will have the same issue. You need to know the machine needs maintenance. Yearly. I had an issue where the unit stopped working after about 10 months and would display a cryptic code (C2-11). I searched and tried all the "fixes" I could find on-line and more. Called the company (Rheem) and they sent me out directions on how to perform a clean-out of the gas fire plate on the inside of the unit. (This should be performed by a trained professional if you are not extremely handy)It took me about 2 hours to complete the procedure. This will correct the problem and allows unit to run about a year before another cleaning is needed. Most important thing to know is that it is not a maintenance free unit and the dustier the area where it resides the more maintenance it will need because it uses surrounding air for ventilation. Maintenance is only reason not a five star rating. Loads of hot water, even when running two showers at once!

Cleaned out my open loop heat pump using a small general purpose pump I bought at Menards. I connected two washing machine hoses to the two ports installed on my system, put the pump in a bucket with a quart of product and 3 quarts water, and let it run for an hour. This product is mildly irritating to the touch, but quickly cleaned my sight glass, so I could tell it was working. My heat pump is running much less to keep my house conditioned after cleaning it.

When the humidifier arrived I was careful to read all of the instructions. After reading some of the other reviews I was afraid of leaks and damage to my belongings. There are many many cautions in the instruction booklet, 27 in all. Several warnings on how to work the humidifier without damaging floor and furniture. Most of the cautions use all caps warning of NEVER and DO NOT. 27 precautionary instructions feels like a lot for an appliance. I have to say I was terrified to actually use the humidifier. Apparently several misuses can lead to leaks and the mist can cause damage to furniture and wallpaper and probably art work. So I picked the one room with no furniture, wallpaper or art in it and laid out several towel on top of a level surface and set the humidifier up. I turned the humidifier on for a few hours while making myself busy in the room to keep a watchful eye out for any issues and no issues came up. The flow seemed steady and fresh and there were no leaks. I would like to use the humidifier in a room I tend to spend more time in but the risk of damages is still not yet worth the risk.
I like the look of the humidifier, the cool blue light that is controlled on the panel is soothing and modern. I've only tried the warm mist and it's not actually what we think of as warm but rather less cool than cold. The automatic timer shut off seems like a good feature if  your leaving it on when your going to sleep or as a reminder to yourself if you forget to turn it off after several hours.
I think it's a well working piece and good for anyone with the right sort of set up as instructed in the directions. That means no valuable belongings that can't withstand moisture, a large supply of towels or floor you don't care too much about, outlet far from heaters and appliances, and have the diligence to clean your humidifier at the recommended weekly period. For myself it is probably a little more work than I'm able to put to owning a humidifier but when the months get dry again I might reconsider the labor versus the reward.

It does a good job at cleaning, just don't scrub hard

I got my A/C fully  intact.  I had it mounted and pressed the power button as the A/C began to run I heard a noise as if there is something not sitting properly in the A/C.  After a few seconds of running the noise disappeared, its a little noisy but it does the job, that is why I gave it 4 stars.

Now after a couple of uses, I can still hear the same noise and now it's constant

My dad bought this for me for Christmas. I have been using it to make a small batch of jerky every month. Today, on the eighth use, the fan stopped working about 10 mins into making jerky.

It's very easy to use and cleaning isn't bad. Until now it has worked great, but I think I will look at other brands with better warranties.

We purchased this Whirlpool Air Purifier in June 2014. We have it in a bedroom we use for our two birds. This unit seems to do a good job of controlling the bird feather dust and the unit is very quiet compared to an older model from a different manufacturer. The pre-filter light had moved from new to the middle light position. Based on past experience I checked the pre-filter and found it was very dirty (it was doing its job, well). After replacing the pre-filter, the pre-filter light will not reset to the "new" position. This is not a big problem for us as we do check the filters periodically no matter which light is illuminated, so I probably won't be asking for a unit replacement. However, if you are one who prefers to go by the filter servicing indicator lights, be aware, that after replacing your filters, your warning lights may not reset properly. Other than the light reset problem, I am very pleased with this air purifier.

On a whim, I threw this in our front-load washing machine on the 'gentle' cycle.  The glue that holds it in a circular shape did let go, but other than that it came out in decent shape.  I was able to put it back in my humidifier (I have the style where the filter is surrounded by a plastic ring that helps it hold its shape, so I didn't have to worry about the glue letting go) and get another week of use out of it.

To get the most life out of the filter, I also recommend that you don't run the humidifier full-blast all the time.  Set the humidity level such that there are gaps in the fan's operation.  This allows the filter to continue to wick water all the way to the top, and prevents a ring of minerals from forming half-way down as can happen when the top half of the filter never gets a chance to suck up any water.

First, let me say that it is a great thermostat. I can set any time/temperature for any day of the week, very flexible. The lighted display and filter monitor are also very useful features. But, the most important feature, and the reason I bought it, is the "clean" cycle. When the Clean Air cycle is selected, one can have the fan (only) run for 9+ minutes every hour. Installation was a snap.
I have allergies and I was often congested or "stuffed up" when I woke up in the morning. After installation, I noticed no such ill affects upon awaking. I have been running in clean mode (9 minutes/hour) every night for six months and congratulate LUX for a great little device that certainly improves my quality of life!

It works great but it makes an annoying buzzing sound non-stop and in 12 hrs I have had to empty and clean it 3 times. After being cleaned it starts to get these black dirt marks at the bottom of the bowl. Its supposed to B clean filtered water. It doesn't seem very clean so I have not let the cat use it yet. The pic below is 3 hrs after being cleaned the 3rd time

I would've rated this 5 stars when I first purchased it a few years back. It was quiet and just as powerful as the gas Mantis it replaced. But unlike the gas Mantis which had lots of use for many years before it worked poorly, this one has hardly had any use (we were too busy to garden the last 3 years).

Anyway, I took it out to use this year and it quits after a few minutes (yes, I cleared the roots etc, that is not the problem). I have to wait 5 minutes and then it quits again. Like something is overheating, but I don't smell any burning. For something I've used less than 20 times this is unacceptable.

Bumped up a star from my earlier review because I found it works until it gets too hot. On a warm day, that does not take too long. You need to hit the reset button once it cools down sufficiently (best to give it some time, not just 5 minutes), then it works again. When I had an issue (reported earlier) however, the local dealer who was also  a Mantis support place just sat on the machine even though they told me it would be a week (need it for spring planting). Mantis has a 5 year warranty on this model ... but according to them it ony applies if you bought the Mantis directly from the company. With this kind of support, i can't give this 5 stars.
