The filter replacements for the HEPA filters are 100$+ each, hard to find, and the unit does a poor job of humidifying the air. I sincerely regret purchasing this and wish I could return it.
Received within 2 days , perfect packaging, unit work as describe… no panic !!! the off button is for shuting down the unit not to start … if you unplug and plug the unit, do not press « off » button « ..use the « clean air as « on button » to re-startButton ..
Excellent value for the money. I have had this unit for aa little more than a week and In my opinion It purifies air just as well as more expensive units , the filters last longer and are cheaper than other models. These features combined with the integrated humidifier makes this unit an excellent choice. Since I have had it my daily morning coughing fits have stopped.
I ordered the one without a box and saved a bundle.
Great machine with great design. We are happy to get this one . It is good to have this during this season. It is great, but it is expensive.
Good seller, Great unit.
I have bought many different humidifiers, including ultrasonic, large and small, with and without filters. I have bought many different ozonators. I have used many essential oil diffusers. I usually get sick within a few days of travel because of the dry stale impure air. I used to have an immediate reaction to mold; many hotel rooms have mold. Many homes on the ocean have areas that are musty. I stayed in a house on the ocean that had one of these humidifier/purifiers and left as healthy as I arrived. For the first time when traveling, I had no sore dry throat, coughing, plugged nose, headache and all the other symptoms that go along with dry unclean air. I bought one of these immediately for my home. What a difference in air quality!
great machine. its very sensitive and with the heat on this winter the humidifier is a great addition to what i need.
This products has digital Hydrometer display. Easy to see Hydro level. Very silence so no problem to use if setup distance 3 meter from beside of bed. This machine keeps good condition my throat condition to avoid coughing and avoid to itch due to dry skin. Spare parts are available at Canada. Ag+ ion cartridge is effective to avoid mold corrosion in the tank and water filter. No timer function available. If it is available, this is perfect product.
Air purifier is working fine. But no moisture came out when put it on Clean Air & Humidify. I filled up the water tank and turned it on, then, I found the water still full in the tank three days later. Even I turn it on the max still no any moisture come out. Should I return?
I bought a Sharp Air Cleaner 10 years ago and needed another one for a second bedroom/office. It is silent on the low fan setting unless you are standing next to it, and then it sounds like a quiet breeze. Perfect for a noise sensitive person like myself. It was recommended to me by a staff member at Sharp Electronics of Canada and the customer service was very much appreciated!
très bon appareil et qui fait la ¨job¨par contre un peu trop chers?
It starts making weird noise after a month later.
As silent and efficient as advertised (check out youtube's videos. I confirm, they're for real), this is quite an impressive piece of electronic that does filter out most of the smaller particles. I have not yet tried to wash the filters, but I have used my vacuum cleaner to clean the hepa filter.The KC860U can handle one room, but not more. I loved the first one so much that I bought a second one for the living room.With my NEATO vacuum robot and these Air Purifiers, I hardly have to dust my rooms anymore.The humidifier is quite a plus even though you must refill it daily, sometimes faster.BTW, Amazon's customer service was absolutely fabulous in handling my issues with one of the Air Purifier.
If you live in Ontario or in any other place with moderate humidity, you don't really need a humidifier. In my apartment I have 40% humidity level during heating season, which will easily exceed sanitary level (50%) if you turn on this thing. People suffering from asthma should AVOID ionizers as they generate ozone and irritate your lungs. If you want to improve you air quality buy a purifier that features only HEPA and carbon filters with CADR adequate for your living space footage without above mentioned features.
Working well and very quietly. Bought second one after two weeks.
