Alen A350

I've only had this air purifier a couple of days, and I'll definitely come back and edit this review if anything changes, but so far this is BY FAR the best air purifier I've ever had. I have allergy… problems, and have used air cleaners in my bedroom for years. They've really helped. I've owned those made by Honeywell, and a top-of-the-line by Friedrich. This one is so much better. Pros: 1) SO EASY. Nothing to install or put together. No long instruction manual for use. You take it out of the box, plug it in, and turn it on. That's it. 2) The button controls are very intuitive and easy. You press "on", adjust it to the speed you want, and push the iodizer button. 3) This unit is very slender and takes up a fraction of the room of my other purifiers. Plus, it's aesthetically really nice, which is great. 4) It does make a white noise sound, but I love this. I have gotten used to the sounds of air purifiers at night, and am at the point now that I sleep better with it. The great thing about this purifier is that the white noise is so consistent with no cracking or snapping sounds. (The problem with the Friedrich I owned just before this.) 5) Within a few minutes you could already smell and feel the difference in the air - it's that good. 6) There is an light indicator that tells you when to replace the hepa filter. It's supposed to last round 6 months, and although I haven't had to yet, it looks like it's easy to replace. Nothing else to clean or maintain. Cons: For me, nothing so far. But if you are looking for an air purifier that is silent, this isn't it. As I said, it does make a white noise sound, and the higher the power the louder the noise. But for me this was a plus since I like that sound and with this unit it's particularly soothing and consistent. Highly, highly recommended.

I bought my pair of Alen 350 airpurifiers from Air Purifiers of America. The first unit was defective and was very load and screeching. They sent me a replacement and the replacement did the same. The third… unit seemed ok. Within a month the other unit did the same thing so I got another replacement. Now it is about 9 months later and what do you know the last one to be replaced is now making a load noise as well. What do you expect, it was made in China! Although for the price I would expect a much better quality. I would not recommend this unit to anyone.

I received this unit as a Christmas gift (I've been suffering from some pretty nasty allergies), and I love it! It's fairly loud and high-throughput at the two higher speed settings, but it's whisper-quiet… at the lowest setting and creates a pleasant gentle breeze. I've got it positioned under my (quite large) desk, so I usually run it at the lowest speed when I'm working at my desk and at the second-highest speed the rest of the time. It's a great white noise machine at the higher setting (we've got several neighbors with dogs), and it really has improved my allergies. If I leave it off for a day or two, I start to feel the difference in the morning with stuffy nose and scratchy throat. It's been incredibly helpful. Also, the fact that it has a little series of lights to remind you when to change the filters is great. I haven't had to replace them yet (yay!), though it looks like I'll have to put in a new filter in 2-3 months. This is probably one of the best gifts I've received.

My first Alen A350 failed within 30 days -- apparent blower wheel to blower motor mount failure. After 1-1/2 weeks of emails, Alen did replace the defective unit. Within the next 30 days, the replacement… Alen A350 failed -- definite blower wheel to blower motor mount failure. I'm currently writing emails again to get a third A350. It is my opinion that either: 1.) the Alen A350 has a deficient blower mounting design; or 2.) the workmanship of this "Made-in-China" air purifier is poor.
