For pretty close to that price range (assuming USD), the AirFanta 3Pro is by far the best bang for the buck you'll find. Barely over 1 sqft footprint and over 700m3/h CADR. It's basically a pre-built CR box kit, but looks a lot less janky than some filers and duct tape.

AirFanta 3Pro. Nothing else comes anywhere close to the CADR for the price and it's not even that expensive.

Just a couple points of clarification: a good filter for a classroom does not need to be HEPA to significantly improve the air quality.

Do you have air purifiers in your office? You can also monitor air quality and gather data so you have something if you need to take it further.
