Office air is shared air. In a room full of people, CO&sub2; climbs and any airborne bug spreads on the same breath. A quiet, high-airflow purifier is the simplest fix — if it’s quiet enough to leave on during calls.

Aim for 4–5 air changes per hour. A 6–8 person meeting room (~40 m²) needs 400–600 m³/h of clean-air delivery; open-plan floors need one unit per zone. Undersizing is the usual mistake — a desktop gadget won’t turn over a real room.
Noise is the dealbreaker
An office purifier has to be inaudible on a video call. Most HEPA units are loud at the speed you actually need, so staff turn them down — and lose the cleaning. A kit delivering high airflow under 35 dB stays on all day without anyone noticing.
Running cost for always-on
Offices run 8–10 hours a day. At ~15 W that’s pennies a week; standard filters keep the ongoing cost trivial, so facilities teams can deploy several without a budget fight.
