I loved my Alen HEPA Air Purifier and when it failed 5 years later, I was so disappointed.

Now retired, my income forces me to make tough decisions. When I contacted Alen, they immediately reminded me that the product had a lifetime warranty, no questions asked and in 4 days, I had a new machine. So, I started thinking....what other product offers a 'lifetime' warranty without a list of exceptions? amaircare roomaid hepa plus voc air purifierI can't think of any. trion electronic air cleaner console 250Thanks Alen for your great product, your service and the promises you keep.holmes air purifier hap-293Will in Maine from Lincolnville, Me 1/27/13 We had an Alen HEPA Air Purifier that began to malfunction, and I was so disappointed - this purifier was an investment (we bought 2 of them) and it was needed for an allergy sufferer.

But thanks to Alen Corp., I made the phone call to see if it was covered under warranty and hoped they'd repair it and much to my relief, they had all my info and after troubleshooting, they determined to replace the unit. I am so pleased. This action right here, that this company stands by their warranty, has made up my mind that if we need another product like this in the future, we will shop with Alen.happy camper from land of 10,000 lakes 02/03/13 We recently had a power surge come through the house and take out one of our 2 AlenAir 350 HEPA filters. I emailed AlenAir telling of my problem and they immediately began processing a replacement filter for standing by their lifetime warranty. We'll be customers for life. Craig from Richmond, VA 04/24/13 I now own 4 Alen products and am very happy with them. There is a noticeable improvement in air quality with this product. The air purifiers run 24/7 and really help reduce the dust in the house. They are kind of pricy but they are of good quality, do what they advertise, and the company really stands behind the product.

The customer service folks are very helpful and they help to resolve any issues that might arise. I had a defective product and they immediately sent out a new air purifier. So to sum it up, really good product that is costly but worth it. This is one of those times when you get what you pay for!!! I have had this air purifier for almost 5 year to help combat asthma. Since setting it up in my bedroom, my asthma issues (caused by having 4 cats) have pretty much disappeared. Regarding customer service, I recently had a problem with the purifier, and Alen acted promptly to fix the problem. I was amazed by how quickly they reacted (or that they reacted at all), given the age of the purifier. I highly recommend this product. hockey5 from Buffalo, NY 12/26/12 I bought an Alen unit back in 2009 and we run it constantly. It died last month and Alen sent us a new one - I was truly amazed at their customer service and warranty follow through. In today's world, you just don't come across many companies like this one!

Thank you Alen for standing by your product so admirably!Sonya from Kentucky 9/3/12 Alen will, at its option, either furnish a replacement part or replace your air purifier provided the product is determined by Alen to be defective as a result of faulty material or workmanship while in normal use. Replacement parts or units will, at Alen's option, be either new or refurbished. Alen's sole obligation under this warranty is to replace defective parts or replace your air purifier free of charge. All parts or units that are replaced become the property of Alen. This warranty will be valid only for units in possession of the original purchaser. Proof of purchase must be presented to Alen's warranty service representative. To help us validate your warranty, we encourage you to register your Alen HEPA Air Purifier.

We’ve just survived yet another winter night with the US Embassy’s air pollution AQI maxed out “beyond index” over 500, so it’s again a good time to review one of Beijing life’s unfortunate necessities: indoor air purifiers. In our expat world’s never-ending discussion of the best air purifiers, many of you have read my article detailing my head-to-head battle of IQAir 250 Pro versus Blueair 501. Now we can add a third player in my personal tests: Alen Air. Alen Air is a Texas-based company which makes air purifiers, and a couple months ago their local rep invited me to test out (not keep!) two of their machines at my house: their flagship A375UV machine, and also their Paralda unit. So I spent a couple days comparing these brand-new machines with my trusty stalwarts, my IQAir and Blueair. First, The Boring Tech Stuff It’s very important to know that my home’s machines did not have new filters, so true comparisons to these new Alen Air machines cannot be done.

My Blueair’s filters were at least 4 months past prime, and my IQAir’s pre-filter was in the red zone. (Still, their data is also interesting). Anyway, I spent a few days wheeling around each machine in one of 4 rooms: I then measured each room’s pollution levels with a handheld Particlescan machine. This machine measures PM0.3 particles, which are much smaller than the PM2.5 which the US Embassy monitors. These tiny particles are what most scientists think are the causes of pollution-related lung and heart disease, as they easily get absorbed into the blood stream via the lungs. I was “lucky” enough to be testing on days with the US Embassy readings in the high 200’s, so this was definitely a real-world challenge for any purifier. The good news is that both Alen Air purifiers did quite well, and indeed better, than last year’s tests of the IQAir and Blueair. For example, on average: Another very positive point is that all purifiers did really well in bedrooms with doors closed.

In fact, all four machines at maximum settings removed 95-99% of PM0.3! At quieter settings it was less awesome but still very good. I think this is powerful proof that air purifiers in bedrooms can dramatically reduce your pollution risk while you sleep — an issue especially crucial for infants and children. In last year’s results from my previous apartment: Compared To Outdoor Air? Don’t forget that the above numbers are comparing filtered rooms to a “control” room in a separate part of the house. So if you compare these above numbers to outdoor air, they perform even better. For all readings, I also stuck the Particlescan out of my 15th floor window and recorded this data. On average, indoor air PM0.3 in my unfiltered hallway was 53% of outdoor air. I think that’s pretty good, and it’s a lot better than my previous apartment a couple years ago, which usually was around 70%. I think it shows how proper ventilation and window protection can help. But what that also means is that these machines did even better than the numbers above.
