  • Broke after 6 months - terrible customer service!
Size: Dust, Mold, Odor + Smoke Color: White
I liked this air purifier in theory but it was quite expensive and turned out to be defective. Alen's return/replacement guarantee put me at ease. However, after six months of use, the air purifier just stopped working and wouldn't turn on at all. I emailed, called and attempted to chat Alen but received no response except for a canned email asking me to call in to "begin the replacement process". When i called in i was on hold as "first caller in line" for over 30 minutes. DO NOT BUY! This product is DEFECTIVE and they WILL NOT REPLACE IT even though they have a WARRANTY. ... show more

  • Don’t let marketing ruin a good product.
Size: Dust, Mold, Odor Color: Espresso
The unit arrived 10 days ago and has been running smoothly and quietly,. It seems to cover quite well the entire living room area of about 800 sf. Then I noticed that the more recent Allen models have designations for bedroom, living room, or kitchen which is the model I bought. I held off my review until I received the clarification from the maker that each model can be used in any room in the house, and that the designation is just a marketing ploy. If it is ploy, I am not sure it is a clever one. Instead of being lured to buy different units for different rooms, I was tempted to return the one I bought thinking that the unit is not designed for the purpose intended. Straight forward description, honesty in other words, is still the best policy. ... show more

  • Helped With allergies!
Size: Dust, Mold, Odor Color: White
I bought two of these directly from Alen around 6 weeks ago. I have 3 cats and one dog in an 1100 sq foot town home. I love having these! They keep hair and small dust out of the air and any time I cook (I do a lot of high heat wok and Indian cooking) it clears the smoke and smell within 30 minutes! The noise on high is noticeably loud in the bedroom so I keep it on 3/4 and the one in the living room I keep on turbo (4/4) all the time. It is a relaxing, methodical, low pink noise that I actually enjoy having at night. As a note, the filters for this are the same as the “Flex” filter by Alen. Update: been a bit over a year and I’ve replaced the filters twice. I’ll admit, filter replacements are a bit pricey. But the quality of this unit is great. I move them around often, keep them running 24/7 and the performance has not diminished. The noise level is also the same as when I purchased. Update: about two years now and still not happy with filter cost but they’re working great! Keep an eye out for periodic filter sales. Update 2: 3 years since I got the 45i and it’s awesome. We have two now. Absolutely no change in performance between now and 3 years ago. Can’t recommend it enough! ... show more

  • Now we can keep our cats.
Size: Dust, Mold, Odor Color: White
I was recently diagnosed with strong allergies to cats and grass. Our family has two beloved cats- in our family for 10 years. Getting rid of them isn't an option for us, so I looked at ways I might lessen my discomfort. This HEPA Air Purifier has made a huge difference! I have had no itchy skin issues or blistering around my eyes (caused by pet dander) since we began running this purifier in the home. I'm grateful for the physical relief and for the chance to keep our family together. ... show more

  • Good but broken 6 months in with no support
Size: Dust, Mold, Odor Color: White
Unit was easy to set up and use. However, 6 months in and my unit is having several issue. - fan is loud - auto mode is always on high I emailed and contacted the website warranty without any response. Buy at your own caution that they won’t honor warranty.

  • Perfect
Size: Dust, Mold, Odor + Smoke Color: White
I bought this 3/27/19. I Intentionally waited to give it a review because I wanted to see it if worked. I got this for my basement that always has a musty oder to it and I have severe allergies! I love it. Not only is the smell gone in my basement but Im breathing better. The indicator on the unit that tells you what the air quality is my favorite part, bc it lets me know its working. I have it set on auto so it senses when it needs to come on. Already thinking of buying one for my rooms upstairs. ... show more

  • Returned and bought on sale directly from vendor - Very good at filtering
Size: Dust, Mold, Odor + Smoke Color: Graphite
This ordered was canceled due to misunderstanding about Amazon's payment plan, but I did purchase it anyway from the vendor itself on sale for about $50 less. The purifier though expensive is top notch. If you buy this I would recommend to also buy the pre-filters which now sell on the vendors site. To power it off is a bit strange. You have to press the power off button twice. They do this because some people don't like the light shining when sleeping so it's like a toggle between the function buttons having light or no light. The replacement filters are expensive, but I run this all day greatly improving my sinuses. It is nice and quiet, and looks nice anywhere you place it in your home. ... show more
