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 on Reviewed in Canada 21 November 2025* The Sharp humidifier has been an exceptional addition to my home. 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. ### ⭐⭐⭐⭐⭐ Great unit - watch the prices. *by on Reviewed in the United States 20 January 2014* 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. ### ⭐⭐⭐⭐⭐ Ticking sound actually helps me, and air is clean! *by on Reviewed in the United States 10 December 2022* 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! ## Frequently Bought Together - SHARP Air Purifier And Humidifier With Plasmacluster Ion Technology For Medium-Sized Rooms.
