Easy to set up, quiet, sleek, medical grade hepa filter, lots of color options, user friendly. I chose the weqthered gray because it matched perfectly with my furniture!

I didn’t think I’d like its graphite design but if it turned out fitting nicely with my home. Setup is very easy. No hassle or programming. I love that it has a colored-light system to indicate the level of air quality in the room. I also love that it not only has a true HEPA but an activated carbon filter as well! Full coverage! Better peace of mind now. Before the air purifier, my home had this strong aromatic scent. It wasn’t a problem. In fact, my friends say it smelled good in my apt. But after the using the air filter, the aroma is gone. I sort of miss it. But I’m not too bummed… My home feels so much fresher!

im so glad I decided to get this product when I did, not only is it helping keep my house cleaner and fresher from odors but it also helped regulate the air quality this week from the forest fires
I wouldn't have even known how poor the air quality was until the machine was on red and purple mode for hours only then did I realize there was a haze out my window and I was having trouble seeing the Las Vegas strip from my room
if you have pets or seem to just have musty odors then this product will help a lot instead of just covering the issue with scents and fragrances which can be just as harmful

This is my fifth purchase of Allen air purifier models.
They run quiet yet very effective in cleaning the air.

Best Air Purifier

I took time to read all the online and YouTube reviews for HEPA Air Purifiers. This one really stood out. There are also multiple filter options from the manufacturer which was a big plus. There are several face plates available so it can blend with your home's design. The filter assembly is also very tightly sealed which acknowledges the whole HEPA aspect of this Air Purifier.

I don't know too much about air purifiers so this was one time I defaulted to consumer reports to guide me and they say that the Alen brand air purifiers are the best out of like 50 brands that they tested and I really don't have anything to compare it to however my kids allergies are better and I would say we have a 40 to 50% reduction in dust lying on various surfaces around the house.

Classy looking and effective air purifier. Lasts longer than other purifiers before a filter change is needed. Able to fit into tighter spaces than most other models.

Works well so far. First model sent was a repackaged return even though ordered as new -- even had last delivery information in the box. Returned and second delivery was new and works well.

No complaints! Runs well and has cut the pollen and dust down where we sleep. One still needs to vacuum off the dirt from the pre-filter every 2 weeks. First Filter from the Alen Subscription arrived this week. Old filter is still doing well for being 12 months old.
