You can manually adjust the fan speed, but we typically leave ours on Auto Mode in the main living area (the larger model that covers 1,400 sq. ft.). For the Compact Pro versions, we prefer using Eco Mode. In addition to the HEPA filter (which doesn't need to be replaced for five years), the Compact Pro also features one washable mesh dust filter, while the larger model features two! It's easy to maintain—you simply vacuum it off, and the purifier will notify you when it’s time to check it.
The odor neutralizer, located at the top, can be locked into place and manually adjusted to increase or decrease the amount of odor control. While it doesn’t completely eliminate strong odors (especially lingering kitchen smells), it noticeably freshens the air and helps restore overall air quality.
When you first turn on the purifier, your starting air quality might register as poor, which is when the unit is at its loudest. As the air improves from poor to fair to good, you’ll notice the noise level decrease significantly.
The round design looks sleek and modern, but it's not as easy to place flush against a wall. However, it fits nicely into corners, so placement has not been a major issue for us.
Overall, we’re very happy with these purifiers and would definitely recommend them! Both the larger and smaller are pictured individually and together.
