If you're looking for a nearly silent purifier, this unit does it. Granted you need to keep it on low for those super-quiet noise levels.
Pros:
* Filters extremely well
* Quiet
* Water tank easy to remove
* LED lights can be turned off
Cons:
* Water tank empties in 8 hours on low, less on higher fan levels
* Water tank doesn't have a handle for holding it "upside down" while filling. Makes it slightly more awkward when filling in the tub bent over.
* Unit is decent sized and is floor model. It's no huge, but it's not small either
The unit also has LED's the purport to tell you how "clean" the air is... how many particles are floating in the air. My house gets quite dusty, but I've still never seen the unit display anything but "all green" on this display. Perhaps it doesn't work on my unit, or perhaps it doesn't work well. And it's this gauge which makes the unit go into a higher fan mode when the air is dirty and the unit is in auto mode. So my unit never leaves low fan. So at this point I manually turn it to medium or high when I'm not in the room.
I'm not sure if it's worth the price here on Amazon, > $350 currently. But I also have never purchased another purifier. Maybe it does work much better than the competition and is worth that price. However I found the unit on clearance at Best Buy and paid less than $200. At that price point, I consider it a worthwhile investment.
we have both 850 and 840 units in our house. the 840 is more than enough for even a large bedroom, and the 850 is great for the family/living room.
the units are silent and because the fans are " behind" the filters, should remain silent forever.
there are 3 stages of filters, a dust screen, particle filter and then HEPA. you will never need replacement filters, so dont be paranoid and buy spares or anything. every month you just vacuum the back of the unit to clean the dust filter. I also vacuum out the particle filter each month and sharp recommend washing it every couple of months.
we live in a dusty environment and we can " taste" the difference in the air with these running, they do an awesome job.
we have them running on automatic and to give you an idea about how sensitive they are to odors and particles in the air, in the morning when I spray deodorant ( in the connected bathroom), the unit detects it and goes overdrive!
I would recommend these to anybody, as im surprised how much they have improved our quality of living.
Buy Sharp KC-850U Plasmacluster Air Purifier with Humidifying Function Now
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.

Want Sharp KC-850U Plasmacluster Air Purifier with Humidifying Function Discount?
I recently purchased the Sharp KC-850U. I suffer from allergies and was looking for a solution. I placed the unit in my bedroom, and I have to say after one weekend of use, I am certain that this purchase was a great decision. I am going to buy another unit for my home. Although this is more expensive than other units on the market, the simple fact that it releaves my symptoms and allows me to breathe easier is worth it. I have had other purifiers and none have come close to this unit. It is quiet and does a great job of both removing allergens and humidifying.
I highly recommend this unit.

It does what it says it's suppose to and it's easy to clean and fill but it leaks very bad when you get to the low water indicator and the light turns from blue to a orange. You are suppose to refill it when it gets to that point but when you are asleep all it does is make alot of water under whatever it's on top of. We ended up putting a thick bath towel under it when we run it at night to soak up the moisture. It only runs for about 7hrs on the high setting but the ad said it would run for like 24hrs, so don't believe everything that is posted. We do wake up less congested and it does kindof heat the room up because the hot steam that it puts out but I think next time we will look for one that doesn't have a leaking problem.
