Wild Fire Relief
Quiet, modern design, easy to operate, this air purifier is a hit around our house, especially since we have experienced the effects of multiple local wild fires. We run it 24/7 to keep our home’s air breathable and healthy. My only concern is that there is no way to actually measure the air quality in the house. Our peace of mind is anecdotal at best, but we do feel better.

Wow! It works.
I have had morning headaches, itchy eyes, in the morning. I try to clear my throat so many times, that I sound like a car engine that won't start. I am tired all the time. I take at least 2 different OTC allergy pills. I assumed that I must live with these symptoms. I have tried other, less expensive air purifiers..but they haven't worked and often emit a strange smell. I often visit a friend with air purifiers in all rooms, and I still have my symptoms. As smokey air, and pollution in general had me coughing, we decided to try a more expensive air purifier but smaller version of Alen, and if we liked it, we would buy two. Well...Alen arrived (his official name, because he is now my new best friend), and all symptoms stopped for the past two weeks. No more saline spray, no pills, no cough, more energy, and no noisy engine. I mention all of this because most reviews never really told me how people felt. Reviews say works good.So I am ancient, had these problem for years, and now..wonder how much time I lost feeling bad. He is the real deal and worth every penny.

Great Addition to my home
This air purifier has been a blessing, it has made it easier for us to enjoy everyday. We just moved to a high rise and our allergies began to kick in, after the arrival of our air purifier out allergies settled down. Thank you.

Best purchase
This product has been running for a month. Our bedroom was so dusty but with the Alen the air quality is improved and my husbands CPAP filters are lasting longer. I’m glad we are on filter subscription. Thank you Alen..

High quality, effective, quiet and stylish
This is our 2nd Alen air purifier. It worked so well for our son's allergies that we bought another one for our bedroom. We love this product. My husband notices a big improvement in his allergies (much less congested). I'm impressed with the quality, design and it's super quiet.

Lives up to the hype
Got this for my home office, which is a very small room that's really more like finish attic space, and doesn't get any air flow so really needs this purifier. It arrived quickly, basically no set up needed. Very easy to use and I really like the feature where I can tap to turn off the display while the machine runs. Only change I would make is timer options--currently there's 2,4, & 12. 8 would be perfect for me in my office, and for the second one I'm about to purchase for my bedroom. It's certainly quieter than any other air purifier I've gotten and I'm very happy with it.
