Does that mean your air doesn't get filtered if you stop or decide to turn down the white noise?

I prefer having quiet air filters that I can run all day (based on air quality) instead of noisy ones I only use at night.

If you turn it off, sure.

I have one in the bedroom. On low, I barely hear it during the day (extra ambient noise from outside) but at night the white-noise is subtle but effective. That said, I don't like "loud" white noise, just a quiet hum.

For air filtering, you want big fans that move relatively slowly. At least, at lower settings.

I still haven’t seen anything else that can compare to IQAir HyperHEPA filters. They use these things in hospitals.

Many air purifiers are silent on lower settings and louder on higher settings. If I want noise I turn mine up. If I want less noise I turn it down.
