Walmart has some portable HEPA air cleaners which work good. Get the
largest model and the fan noise will be the most quiet.

HEPA air cleaners (the best air filtering you can buy) are also good for
allergies and can filter illness causing particles out of the air. Point
the clean air output toward where you sit.

I work in an environment where there is second-hand smoke. I am
considering
buying a portable air-cleaner to take with me to that job. Does anyone
have
any recommendations?
