11 Air Purifier Brands You Can Actually Trust to Breathe Easier

6. Alen — Fans Love It, But Reliability’s a Question

Alen’s all about air purifiers, and people really like their products — user satisfaction is a perfect 5 out of 5. But reliability scores only 3 out of 5, meaning you might run into some issues over time. Their 45i and 75i models are recommended by Consumer Reports and work well in medium to large rooms. If you’re okay taking a chance for great performance, Alen’s worth a look.
