Raise your expectations of an air purifier and ensure a lower total cost of ownership over the years. Other brands may suggest replacing the filters every six months; that can really add up! Both the SHARP long-life True HEPA filter and the long-life Activated Carbon filter last up-to 2 years, depending on the environment.The triple filtration system helps clean the air that passes through the filters in three ways. The washable, microscreen pre-filter traps dust and other large airborne particles. The activated carbon deodorizing filter helps reduce some common household odors. Finally, the True HEPA filter effectively captures 99.97% of particles from the air that passes through the filter from 0.3 microns and larger. Beyond passive filtration, our FXJ80UW features Plasmacluster™ Ion Technology for an active cleaning process. SHARP Plasmacluster™ Ion Technology has been tested around the world by laboratories in the United States, United Kingdom, Germany, Japan, South Korea, China, and Vietnam. The FXJ80UW is AHAM Verifide Tested to provide a Clean Air Delivery Rate (CADR) for three common irritants and allergens, Smoke (324), Dust (334), and Pollen (361). It is certified by the California Air Resources Board (CARB) to meet its strict emission standards. The FXJ80UW features Max, Med, and Low fan speeds, plus Pollen, Sleep, Express Clean, and Auto. In Auto mode, the dust and odor sensors will monitor your air quality and adjust the fan speed automatically. Auto mode also uses a light sensor to adjust the brightness of the LED display according to the ambient light in the room. The Library Quiet™ Sleep setting is perfect for the bedroom. SHARP Plasmacluster™ Ion Technology has been used in over 100 million products worldwide, including leading auto makers and refrigeration appliance manufacturers. It’s no wonder people around the world trust SHARP. Now that is Simply Better Living.

Review: Very happy with this air purifier with humidifying function!!! - Updated Feb 10,2016 It's still working just fine. I've been using it everyday since I got it. Especially winter when it's dry and cold outside. I usually have the windows and doors closed coz it's cold and the heater is on. Hence the air purified is needed plus humidifier helps me a lot at night through out my sleep. The filters are still doing great. I washed the charcoal filter ( black one) once in awhile and still work like a champ. I can't say enough how much I love this air purifier which help me to get rid of allergies and flu ( Plasma cluster kill the virus and bacteria in the air). At this point I know it sounds so cheesy but I can't live without it in the daily life. Worth the money and best gift for myself EVER. ************************************************************************************************ It took some time to write this product review for me but so far I love it and very happy with it.Just to clarify I bought this product by myself I dont get discount to exchange the review. I did a lot of research before I bought it. Here is the reasons why 1. My room is about 498 ft2 ( minus the bathroom, closet and laundry room it's about 350 ft2) which is perfect size according to product info it's for room up to 347 square feet. However when you buy air purifying you can calculate by using the number of AHAM Certified CADR x 1.5 = capacity of size's room (ft2) for this product it has Dust/Smoke/Pollen = 231/220/245 use the number of Dust 231 x 1.5 = 346.5 ft2 so it's pretty accurate to info of this product.Don't be fooled by some brand that tell you to use for medium or large room but the number of CADR is low because it's not efficient to purifying the air. The higher number the better air purify. Some companies /brands say their products for 550 ft2 or bigger but to be practical it's really not for example Rabbit Air BioGS 2.0 : The BioGS SPA-550A air purifier advertise that will filter all the air in a room up to 550 sq but the CADR as below SPA-550A CADRs / Sharp KC-860 Test Rating Dust 149 /231 Pollen 162 / 220 Smoke 135 /245 as you can see Sharp KC-860U is better in every Category with the same price.Don't forget to look up CADR number before you buy air purifier any brands as you know they can say whatever... for mid size room , large room , 550 ft2 625 ft2 or anything but they CAN'T lie on CADR number.It's the same standard that test the products for every brand. 2. This sharp KC-860 has Plasmacluster® ion technology from Sharp.It is remarkable!! It's better than Ionizer.. you know some brands only have filters or might have negative ion technology but Sharp is amazing that purifies the air by emitting positive and negative ions.It deactivates suspended airborne mould, viruses, dust mite allergens and bacteria and also odors like pet, cooking, garbage and cigarette smoke. Like I said I live in studio room which is kitchen is open sometime when I cooked it had smoke a lot and fire alarm went crazy I turn on high setting and everything was fine. (...) (...) 3. Permanent Pre-Filter ( washable), long life active carbon filter ( up to 5 years and washable ) , long life True Hepa filter ( up to 5 years but can't wash it).For me It think this is one think you should consider when you buy air purifier because I know some brands are cheaper but look up on filter they have to be changed every 6 months ,8 month or 2 years cost of heap filter of course not cheap so total cost at the end would be the same but you will get a lot better quality product and definitely more functional and powerful. (...) 4. Sharps's sensor works great !! it detects dust automatically and sensor display change from green to orange from orange to red( if it's really dusty) somehow I find this kinda entertaining. If you set on Auto setting the fan will go on high automatically until sensor is back on orange and green then the fan come back to medium and low eventually. (...) 5. I love this special "Humidifying function" : Unlike any other air purifiers this product has advance and beyond technology. I live in Seattle I know it's rain a lot but in winter it's cold and dry or I usually turn on the heater so the humid in my room is pretty low during this time ( should be between 40 - 60 if it's less than 40 yes virus,bacteria and mold is hard to survive so am I lol however if more than 60 of course mold can grow easily ,bacteria and virus love high humid). This product control humidity and when it's dry or low humid it adds up quickly and constantly.When I sleep I normally set on "clean air and humidify" mode by overnight it runs out of water! wow It helps me a lot when I have the heat on because I hate waking up with dry throat,dry nose and chap lips. ****The tank holds 1.14 gallons, around 9 pints, of water. 6. Sharp KC-860U is really quite on low setting mode ( they have 3 mode high/medium/low). I basically can't hear the noise of it at all when it's on low I saw on another website review this product is among the quietest air cleaners especially considering the air-cleaning power generated. Even on medium it doesn't bother me when I watch TV but on high it could be a lil loud well sound like when the heater is operating. 7. sleek design, very stylish more than that you can adjust the light display ( normal/dim off) - Ion can be on/off - clean air ( only air filter) or Clean air& humidify ( air and humid) - Quick clean : very intelligent mode the fan will kick high first then clean the air for awhile and back to normal mode whatever you set. - Auto mode : adjust,detect and react automatically normally if the sensor display on green light the fan is on low but when it detects the dust the sensor changed color the fan go high and back to low. (...) Cons: 1. Only one year warranty 2. I heard from other review said their customer service is not good in this case I don't know yet but I will update my review in the future What I can ask for more for this price range :) so far I'm very happy with it and if you need more information you can check on the links below.Hope I can help you to decide :) http://www.sharpusa.com/ForHome/HomeEnvironment/AirPurifier/Models/KC860U.aspx?tech_specs=1 http://www.air-purifier-power.com/sharpplasmaclusterkc860ureview.html
Review: Works great, quite on most settings. - I researched a while before finally purchasing this model. While like most other models it doesn't truly have the advertised effects on all but the highest settings it does a good job of eliminating odors and improving air quality on its Auto settings. The filters are easy to clean, and I didn't expect to enjoy the Humidifier function as much as I do in the winter. The noise is tolerable on all but the highest setting and near silent at the lowest. The lights are bit bright, but they can be turned off partially or entirely, but not dimmed. The quick Clean function works well. It brings the fan speed up and down in a way to quickly circulate air, but it's pretty annoying. You don't want to be watching TV or trying to sleep with that setting on. I only use it to prep a room and then turn it back to auto when I'm in the room. There are some good reviews of these products on youtube which was very helpful and I'm confident it was the best for the money in my situation.

### ⭐⭐⭐⭐⭐ Super quiet and easy to use
*by C***R on September 27, 2020*

I never paid much attention for the need for air purifier until the smoke from all the fire in the west where my family and I live. Instantly, I picked 2 of the top of the line of air purifiers by the brand I can trust for its state of the art innovation and technology and reliability: FXJ80U by SHARP. They are well worth paying premium for great technology that will last: I am especially enthusiastic about the SHARP Plasmacluster technology that generates ions that actively eliminates microscopic pollutants. And the double filter system using HEPA filter gives me sense of peace of mind. For example, according to PC magazine, NASA study found that HEPA filters can capture almost 100 percent of particles as small as 0.01 micrometers (or 10 nanometers), well exceeding the standard. To put that in perspective, COVID-19 is about 60 to 140 nanometers in diameter. It’s easy to set up and get going. I am sensitive to noise and this product is super quiet which I love. The app is convenient to use and also love using Alexa to change settings. The 2 air purifiers I bought have been magnificent for me and family, and have been recommending my colleagues to buy SHARP air purifier FXJ80U.
