It’s quiet, powerful, and keeps the air perfectly balanced without feeling damp or stuffy. The water tank lasts a long time, the controls are simple, and the air just feels cleaner and more comfortable. It also runs smoothly with no weird smells or noises. Overall, it’s a reliable, high-quality humidifier that works exactly the way it should, and I’m extremely happy with it. Review: Great for allergy sufferers - We have used this for years in our bedrooms and it really helps with our allergies. I've got the smaller version for my daughter's room. Make sure to get some good quality citric acid to clean the humidifier filter monthly and this thing will last forever. Good food grade citric acid is available here on desertcart and that's what I use, along with a 5 gallon HD bucket. I use the water tank for this thing to weight down the filters carefully so they stay fully submerged. Its not very loud and creates a light white noise for you that isn't too obtrusive. The filters all last a pretty long time and have different change frequencies outlined in the manual. You can get all of the filters from here on desertcart. My allergies are so bad I have to get weekly allergy shots and this really helps. I was also able to get a letter of medical necessity from my allergist so we could claim this on our medical FSA. ## Features - [MEDIUM ROOMS] Effective up to 1,230 sq. ft. at one air change per hour, the KC850U will filter the air in the AHAM Suggested Room Size of 254 sq. ft. at 4.8 air changes per hour. - [LONG LIFE FILTERS] Includes Activated Carbon Deodorizing Filter, True HEPA Filter, and Humidifying Filter.

Are there any dangers?** A: I'm really glad that someone asked this, because I have done a great deal of research on air purifiers. Rest assured that Sharp Plasmacluster generates almost no ozone. PCI technology is not a traditional ionizer. It works very differently so it produces less than 0.01 ppm of ozone - that is five times LESS than OSHA, FDA and NIOSH recommendations. Read packages carefully. Many air purifiers on the shelf don't use the word "ionizer" but still need to report an ozone warning on the package... because they really do use an ionizer. Sharp air purifiers have no such reporting requirement because PCI technology doesn't work the same way and generates almost no ozone. In fact, the way PCI works is to pull-apart microscopic airborne pollutants and turn them into simple water vapor. The video explains the process better than I can: http://www.sharpusa.com/pciIf you are wondering, ozone is a respiratory irritant with moderate exposure. It can be very harmful in high concentrations. It may seem odd that typical air purifiers would have a possible respiratory side effect... after all you want an air purifier for your respiratory health! The truth is that the ionizer in typical air purifiers is there to deal with microscopic pollutants, viruses, bacteria, etc. that are too small for the HEPA filter to trap. So they hedge their bets. Is it worth it to you to kill germs in the air at the risk of possibly irritating your respiratory system? It may make sense for some people, in some cases, in some places, with limited exposure. Personally, I don't want that much ozone in my bedroom where I spend at least 7 hours every night. So I purchased two of the Sharp Plasmacluster Air Purifiers (one with a humidifier for the bedroom, and one without for the kitchen area) I love them! Imagine my surprise when I purchased an Infiniti and the Air Conditioner features Sharp Plasmacluster, too. You can also find it in some refrigerators to fight mold and odors. I chose SHARP for a million other reasons, too - but the question is was about ozone. **Q: Could you adjust the humidifier level on this unit? I have read some reviews complaining that it's too dry when using this.** A: Unfortunately the humidity level is not adjustable. I was concerned about that aspect when I purchased this unit but I have been pleased with it despite not being able to choose the humidity level. When the unit is left on "Auto" in the "Clean & Humidify" mode it keeps our medium sized bedroom around 50% (enough to moisturize your sinuses but not too much to cause condensation on windows). If you wanted more humidity you could have it on "medium" or "max" instead of "auto" though I am unsure just how high it would actually get. **Q: is it worth it to get the humidifier version?** A: I personally wouldn't bother with the humidity version. The largest model in the non humidity version covers more square feet for less money. You can always use a stand alone humidifier. **Q: Water tank refill indicator still on even when water is in the tank. Everything is put right back. Any ideas?** A: Look at the blue float switch. It needs to be “seated” below the tab that projects out from the side. If it’s above the tab, the light will never go off. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Quiet, Powerful, and Extremely Reliable *by A***S on 21 November 2025* The Sharp humidifier has been an exceptional addition to my home.

But just when I ordered it I noticed that there was an other one the KC-8600 which has a larger water capacity. But when I wanted to cancel my first order I was told that my order was already prepared for shipment . Anyhow I like the sharp KC-8500. It is very expensive ( espelely the filters) But you always get what you pay for. I am more than happy with It. Over night I have both running an Auto and you don't hear nothing. ## Frequently Bought Together - SHARP Air Purifier And Humidifier With Plasmacluster Ion Technology For Medium-Sized Rooms.
