    • Ticking sound actually helps me, and air is clean!
Color: White
Review Image by Yuki Yuki
I've used it for a little over a year now, and it's fantastic. I had to move in middle of the pandemic due to the rising cost of rent. But with rising demand in apartments, we didn't have much choice aka carpeted floor. Dad suggested me this, and you can tell it works cuz whenever there's a power outage and i forget to power it back on for a few days, I'll be sneezing haha. Just remember to vacuum or wash the rear filter cover. I forgot to, and dust was caked on - which explained why it felt like it wasn't working properly at one point. The picture is when we were cooking bacon and it smoked lol. It immediately knew there's something's up. (Orange color) So when the light changes color, there's a quiet ticking sound. Honestly it doesn't bother me. In fact, I'd rather it make noise since it let's me know something's in the air. I don't have a great sense of smell, so I can't tell if something's burning. But this does! I know that's not it's intended purpose but it helped me a couple of times. That said, it's soooo quiet. If I have anything going on in the background, I won't hear it. I don't use the humidifier part, but the humidity sensor is helpful! ... show more

    • Great unit - watch the prices.
Color: White
Greatly improves air quality. Purchased via Amazon Prime two months ago, new, for 299. Prices fluctuate a lot on these, and other vendors charge even more. In a dry climate, on high fan speed (I have it in a larger bedroom and as such it really only works on high) you have to refill the H2O tank twice a day. It's worth the hassle. Over the years I've tried Winix, Honeywell, Friedrich, Austin Air, Holmes, and others too cheap to mention. This Sharp has worked the best of the bunch. Not a miracle worker, but does what it says it will. Vastly superior to Winix, no contest. Filters - expensive & not available everywhere. Wish the unit came with at least one extra charcoal filter. 3-5 year filter life seems impossible, could happen if your air is already pretty clean. I'll be surprised if I get two years out of this filter set. Looks great, which is a nice bonus. The color-changing air quality indicator is a very nice feature. The clicking of the Plasmacluster is noticeable on lower fan speeds. The unit is designed & built well. Plastic, but doesn't feel cheap. Recessed handles make it easy to move. Really has improved the quality of sleep in the bedroom. ... show more

    • Does the job. Very quiet.
Color: White
I think this air purifier/humidifier is worth the money. You can barely hear it running. The air is so much cleaner. I've noticed my husband and one of our house pets has stop sneezing. Very simple easy to use controls (that I love) easy to fill water reservoir. We have two lap dogs and a cat in the house and its so hard to keep the pet hair swept up. The hair was always blowing around but with the humidity being higher its easier to sweep and keep house cleaner. Love it. ... show more

    • Great device but a little noisy
Color: White
This a high quality humidifier and works great. The only downside is that it makes a loud gurgling noise when it periodically draws more water. The rest of the time, it’s quiet. Because the gurgling noise is periodic and loud, it wakes me up if I run the humidifier during the night, which is what I needed it for. Unfortunately, I have to return it. ... show more

    • Good Humidfier - Not supported for parts replacement
Color: White
Review Image by Gerald A. Gerald A.
Purchased this product (KC850U) in 2015 - used about 5 months each year in the hot dry season. Works really well for use in bedroom while sleeping. Now the BAD: my unit still works fine except a Styrofoam Float (bottom of page E-17 in owners manual) is on its last legs. This is an item that needs to be cleaned. I have tried to get a replacement part with no success - so I have a good running machine that needs an inexpensive part and not able to obtain it. Calling SHARP support is terrible, they say they do not sell to consumers and recommend a 3rd party that does not offer the part, and the ones they do have say unavailable. BEWARE customer support for this unit seems to be non-existent. I realize I've had mine a long time, but you would expect them to have parts support for units that are still sold - this unit is still available for purchase here and on the SHARP website. ... show more

    • Sharp quality
Color: White
Everything about this purifier is a plus. The only minus or con is there is not a remote. This is my 2nd Plasmacluster from Sharp. The build quality is second to none and the sensor sensitivity is great! It's nice to see the humidity readout that seems pretty accurate. I don't use the humidifier feature so can't speak to that but I am pleased....especially with all the pretty, and functional exterior lights. Happy Sharp customer! ... show more

    • an innovative air purifier
Color: White
So many air purifiers in the $100 to $300 range are essentially the same thing: fan + HEPA filter + carbon pre-filter. You'd think for that much money there would be more to it. On top of that the designs are typically more industrial than consumer oriented. While Sharp KC-850U at its core is still just HEPA + carbon prefilter, it's leaps and bonds better in all the other regards than the market norms. Pro: * The embossed front panel design looks clean and modern * It has sensor that monitors air quality and humidity and adjust itself accordingly * LED light's brightness can be adjusted and turned off Con: * The humidifying functionality is rather weak, it's not enough to replace my stand alone humidifier in the living room * replacement filters are expensive, according to the manual the HEPA filter (around $100) and carbon filter (around $60) good for 5 years, humidification filter ($35) is good for 2 years. You can wash the carbon filter and humidification filter, but in my experience they can only be washed so many times before they wear out. * These Sharp air purifiers are far from mainstream, makes me worried how long I'll be able to purchase the filters before they are discontinued I'm tempted to -1 star for the lackluster humidification performance, but the unit is so well designed with great attention to detail comparing to everything else I've seen, it deserves a 5. ... show more
