    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!

    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.

    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.

    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.
