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.

YSK on low you won't be getting much air cleaning power. All air purifiers are rated based on their top fan speed.

Housefresh, which is a criminally underrated review channel btw, recently did a comparison of PC fans for this purpose. The Thermalright TL-14C family came out strong in the "Silent" category, with the best ultra-quiet 24/7 fan speed performance. This comes at the cost of slightly worse max speed CADR vs the venerable Arctic P14.

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.

IQAir HyperHEPA is substantially worse than the AirFanta 3Pro. The 3Pro gives you about 10x more clean air per dollar (2 CFM/$ vs 0.2 CFM/$), and 2.5x more clean air at a given noise level (45dBA: 213 vs 86 CFM).

I agree big fans moving slowly is better all else equal, and something AirFanta-like that used a 12" fan could be even better.

All my air filters are sized to clean air while being quiet.

Turning them up to med/high would just cause too much airflow.

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.
