PRODUCT CLAIMS
Check a claim only when you see it
“Covers a large room”
Find the air-change rate behind the number. One air change per hour is not the same as repeated cleaning during smoke.
“True HEPA”
Useful for particles, but not proof that the unit moves enough air for your room.
“Removes smoke”
Smoke CADR measures particle cleaning. It does not prove removal of every wildfire gas or odor.
Built-in air sensor
Useful for trends near the machine. It is not a whole-home measurement.
Auto or smart mode
Convenient, but it does not replace enough airflow. Continuous operation at a useful speed matters.
