Sharp Plasmacluster Ion Air Purifier with True HEPA Filter

I've tried so many air purifiers due to my allergies but realized how ineffective they were after reading an article about how manufacturers claim it catches 99.7% particles (but don't specify the size of the particles). From the Vornado AQS 500 to the Honeywell, they just didn't help at all and I still found myself relying on Zyrtec and Allegra just to alleviate my headaches.

After a month of using the Sharp FP-A8OU-W I can honestly say this is a really good machine despite the high price. Whenever I feel the my sinuses acting up, I hit the quick clean and my symptoms vanish after 10-15 minutes. It's extremely quiet and has an auto-sensor on how dirty the air is. I thought mine was broken because it was constantly green, but when my cats jumped up on it once it switched over to orange (dirty cats!) which was interesting but it still stayed on low. Regardless, I just hit that quick clean when needed and it goes full blast for about 5-10 minutes or so and reverts back to low which is nice. I don't know if that Ion plasmacluster actually does anything but sound cool but I'm not complaining since this is the only air purifier that actually worked for me.

This is my second one of these. I have pretty bad asthma and have tried out several different purifiers with mixed results. With this purifier, however, there is a noticeable difference in air quality. It is quiet and barely noticeable on the low and mid settings. I like having white noise when I sleep, so I will usually leave it on high at night despite the fact that it is a little loud. It kind of works well for noise cancelation. The plasmacluster ion system does make a kind of clicking/beeping sound, but you can turn it off or on as you wish. The most important thing for me, though, is that it really helps remove dust and other allergens, and it has really helped with my breathing.

I thought I was going to die when I first got my cats. It turns out I have been highly allergic my whole life and never knew, WHOOPS!

Anyway this keeps the amount of dust and dander to a minimum in my house, which is not only great for me physically, but it also creates a lot less dusting and cleaning for me. It's not FLAWLESS but coming from a house without an air purifier, I would never go back!

This is also really easy to clean, and its super quiet unless you put it on the high settings, but on auto it's like SILENT. I have it in my living room right behind my couch where I watch TV and it never disturbs sound conversations. The only time it get loud is when it needs to be cleaned, and it will only do that for about 10 seconds, all of a sudden you'll hear the fan kick up into high gear and the little red light comes on that it needs to be cleaned, and then it goes back to normal until you get to it.

I really think this thing is great, it's a lot quieter than my Honeywell HHT-081, that thing started knocking about 4 months into it's life. (I still run it, but in the basement away from me) This thing is as quiet as the day it came out of the box and has earned it's right to the living room!

Amazon did a quick RMA on the first one which worked intermittently. It probably had a circuit board fault.

This unit is in our large bedroom which is carpeted (for now). I suffer from bad allergies to pollen, dust, and molds, resulting in sleepless nights with nasal congestion, drainage, and sneezing.

So far I haven't woken up with congestion since using this machine, but the pollen count has been low. It runs on the low setting which is very quiet, barely audible, and uses only 4.8W (medium is 20W and high 98W). The air in the room always smells fresh and dry, especially when entering.

One thing that applies to all room air purifiers is that you have to keep the doors closed so that it isn't trying to purify the whole house. I open a window sometimes for fresh outdoor air, but I won't do this when the pollen count is high. I might put a spring hinge on the bedroom door to keep it closed.

Along with a routine of clean bed clothes, vacuuming, washing hair in the evening after being outside with lots of pollen, and nasal irrigation with a neti pot at bedtime, this air purifier should really aid in a good nights' sleep.

I'll update this review in the spring when the pollen counts are very high here in northern California.

We like Sharp's FP-A80UW air purifier. It has "plasmacluster ions" function to reduce germs and odors. The function can be automatically activated by dust sensor. The downside is that there is a noticeable fan noise (but not the irritating noises) when the fan is set at its maximum speed.
