Very quiet
It is expensive, but this is a very well made smooth unit that is very quiet. On medium it's still more quiet then the cheap fan in my computer. It does move a little bit of air, which can be cold if your sitting in front of it. So I moved it sideways, and now it does not blow air on me. The filter looks to be good with more cubic inches of actual filtration compared to the cheaper quacker box filtration units.

Exactly as described
I ordered this unit last week and received it yesterday.
I must say, I am impressed and I knew I would be. This is such a great purchase. It has three speeds, the lowest is very quiet. I usually have it on 2nd speed because it is no louder than a small desk fan. The highest speed is about a loud as the AC on high, although I slept with it on high last night and didn't notice and I think I'm a light sleeper.
Overall, this product is great. The "ion" mode says it uses ions to make the room smell clean, but that is hard to tell. I will say, this unit makes my room smell a lot fresher and the air is better. The peace of mind with this unit is great.
The manual says it removes the common "pollutants" of Bacteria, Mold Spores, Pollen, Dust Mites and Viruses. Pollen and mold spores are 10-20 microns and a human hair has a diameter of 100 microns for comparison. So this unit traps very small, invisible particles that you would otherwise be breathing.
Must buy!

Excellent air filter for the price
I received my first unit from Alen and it was slightly defective. The power switch worked, but the speed and Ion setting were flakey. After running the unit (stuck on low and no ion) the unit suddenly started working. I emailed Alen Product Support and they shipped me out another unit within 24 hours. I emailed them back to say it was working fine, but they insisted I get the 2nd unit anyway.
The 2nd unit worked as described and didn't have any problems out of the box. I am giving this product 5-stars based on its overall performance and the excellent Alen customer service.
I would also point out that this is not a "small" unit. At first, I thought it was meant for a desk or small stand, but this is 18" and a sleek 4-5" in width. The unit weighs next to nothing (and there's a smart cubby-handle) if you need to move it around often.
Removing the filters is a cinch and anyone can do this. However, Alen does recommend using gloves when changing out the filter every 6 months (if the unit is used continuously.)
The fan speed/noise factor is very good. The low setting is just quiet enough that one can easily sleep thru it (if placed in a bedroom.) The medium to high settings are probably going to be a bit too noisy if sleeping. It really depends on placement. At 10ft or so, you'll barely hear it running (on the low setting.)
The controls are well-designed and are easily managed. (The lights from the controls may light up a dark room, so that might be another reason to leave it off at night.)
One last note: the base of the unit does have a swivel. So the base stays one direction, and you can rotate the unit about 25 deg in each direction.
