About the Alen BreatheSmart 75i HEPA Air Purifier, Oak
The Alen BreatheSmart 75i is a HEPA air purifier built for large spaces, such as open-plan living areas and big rooms where a compact purifier would struggle to keep up. Alen rates it for areas of up to 2,800 square feet, and it carries a clean air delivery rate (CADR) of 350.
As well as filtering airborne particles, this version is listed as odor absorbing, so it's designed to deal with everyday smells along with dust. It also has an ionic function and is listed as ozone-free. The housing comes in an Oak finish, which lets it blend in more like a piece of furniture than an appliance in a living room or office.
It suits households that would rather run one high-capacity purifier for a large area than several smaller units in different rooms. As with any HEPA purifier, the filter needs replacing over time, so factor that into your running costs.
What reviewers say
Reviewers see the BreatheSmart 75i as a strong performer for large rooms, with fast particle reduction in testing and very quiet running on its lowest speed. HouseFresh suggests it makes most sense for odor and VOC problems and notes low running costs for a purifier this size. The main reservations are a price that's higher than purifiers with similar performance, its bulk, louder higher fan speeds and a fairly basic app.
Pros
- Clears particles quickly in large rooms in independent testing
- Very quiet on the lowest fan setting
- Well suited to odor and VOC problems, according to HouseFresh
- Low running costs for a large purifier, per HouseFresh
Cons
- Costs more than purifiers with similar performance
- Large and bulky, and more than you need without odor or VOC problems
- Louder at higher speeds, and the app is fairly basic
