Air purifier for a small apartment: what matters

For small apartments, quiet + right CADR beats “medical grade” buzzwords.

Checklist

1. Match CADR to the room you actually use most.

2. Check night noise if it will run while sleeping.

3. Filter replacement cost is part of the real price.

4. One good unit in the bedroom often beats a weak unit in the hallway.
