GermGuardian AC5900WCA vs Sharper Image Purify 9

We averaged about 12.23 particles per liter coming out of the fan and basically that came out to be a filtration rate of 98.9. This is the second test...

Let’s start with what we see before moving on to what we can’t see. Visually this air purifier is round with some visible vents and that’s it. And it’s great. It’s simple design doesn’t try to compete with your home decor

This purifier has three speeds: Extremely fast/loud, very fast/loud, and super silent. The super silent speed moves almost no air, but the other two speeds are far too loud. There is almost no difference between high and medium, but then low is just super silent and moves almost no air. I really wish there were a couple of speeds between medium and low

I ordered the Sharper Image PURIFY 9 Whole Room Air Cleaner with True HEPA Filtration, Activated Carbon Filter, Visual Air Quality Indicator, for Home, Bedroom and Office when my dog and I seemed to be experiencing some mystery allergy symptoms and this thing has been a life saver. It's so easy to plug it in and start using it. The touch screen is so intuitive to use, even if you haven't glanced at the instruction manual. Here are some pros and cons of this unit: Pros: - Works amazingly well

Shipping there's a pre-filter which is charcoal, is used and looks like it just bill clothes on and once a month or so you're you want to vacuum this ...

This seems like a well made purifier but it hasn't convinced me that it is really working. I put it in a room with very old (50+ years) dusty carpet and it continually says the air is perfect, which is a little hard to believe.

At this price, it's a great deal! Not gimmicky. Replacement filters are expensive, but I found non brand filters that are within a 1/2" of the germ guardian dimensions. The only reason that it's not getting 5 stars is that I do not appreciate germ guardian trying to profit on the back end with the unreasonable replacement filter prices. Shame on you, germ guardian!! Other than the replacement filter price, great product, so far

The unit will also show you when to replace the filter. It gives off a new "plasticky" smell. I am hoping this smell will fade with time.

Smart design: the intake is on the sides and the filtered air is released upward, making it easy to work into your home environment.

Now repaired, I can appreciate the responsive touch control panel, the simple filter replacement, and the overall esthetic design. The electronically controlled motor is very efficient, using only 2 watts on the lowest speed and only 32 watts on the highest setting of “6” where it moves a LOT of air. Had the unit functioned as received, I would have rated it much higher. Replacement filters are reasonably priced and well made, and easy to change

I have dust allergies and my nose gets stuffy even when there is a tiny bit of dust. After using this air purifier, my nose has gone from feeling 50-70% stuffed every night to about maybe 15-25% stuffed, which is a great improvement for doing nothing but plugging in an air purifier. My only complaint is that the middle speed setting is too loud. High speed is super loud like turning the fan in your car to max

Product: Sharper Image PURIFY 9 Whole Room Air Cleaner with True HEPA Filtration, Activated Carbon Filter, Visual Air Quality Indicator, for Home, Bedroom and Office I got this air purifier in the hopes of improving the air quality as I’ve been experiencing bad allergies. There is a cat in the house and I live in an area with a lot of pollen and dust in the air. I’ve been using the purifier for almost 4 months now, and I can’t see a lot of difference in the air quality. The filter still looks almost new
