Dental practice ventilation design for UK practices: fresh air and extract for surgeries where aerosol-generating procedures happen, a clean-to-dirty airflow in the decontamination room as HTM 01-05 recommends, and air conditioning that copes with equipment heat. HTM 03-01 is our reference for healthcare ventilation, applied in proportion to a dental practice.
Mechanical design for dental practices, from surgery air changes to running costs.
Temperature and humidity controlled room by room. Surgeries, decontamination rooms and server cupboards gain a lot of heat from equipment, and staff in PPE feel it first.
Mechanical fresh air and extract sized so aerosols clear quickly between patients, which also shortens any fallow time that applies after aerosol-generating procedures. Recirculating split units alone do not provide fresh air.
HTM 01-05 recommends air moving from the clean side of the decontamination room to the dirty side and out, so contaminated air does not drift over sterilised instruments. We design the supply and extract to achieve that, and keep odours from materials and chemicals out of the waiting room.
Heat recovery on ventilation, controls that turn air down out of hours, and correctly sized equipment, so savings come from running smarter, not from undersizing.

Common questions about ventilation and air conditioning in UK dental practices.
Mechanical supply and extract that give enough air changes to clear aerosols between patients, controlled temperature, and airflow from clean to less clean areas. HTM 03-01 is the main UK reference for healthcare ventilation, and HTM 01-05 covers the decontamination room. Where current infection control guidance calls for a fallow period after an aerosol-generating procedure (for example for a patient with a suspected respiratory infection), its length depends on the air change rate.
Bringing in more fresh air costs energy, but heat recovery and controls that reduce ventilation out of hours offset much of it. Correctly sized equipment also costs less to run than oversized units cycling on and off.
No. Most wall-mounted split units recirculate and cool room air without adding fresh air. A surgery needs mechanical ventilation for air changes; air conditioning is added for comfort and to remove equipment heat.
Often, yes. Rebalancing, adding fresh-air supply or extract to rooms that only have split units, better filters, and new controls are common upgrades. We rank the options by cost and effect so you can do the cheapest useful fixes first.
