Details readers usually want to know
How to size it correctly
For the “noticeable difference” most people want, size around the higher air-change guidance (the smaller square footage number). Use the larger number as a light-maintenance baseline for big, open areas.
Where it shines
Bedrooms and offices—especially if you want quiet operation plus app control. It’s also a solid pick for allergy season in smaller rooms where faster air turnover matters.
Pets, smoke, and odors
The carbon layer helps with everyday odors, but for heavier smoke/strong pet smells, run higher during peak times, then drop to a lower setting to maintain clean air.
Filter maintenance
Keep the intake clear and replace filters on schedule to maintain airflow and performance. Pet homes usually need more frequent filter changes.
