HEPA Air Purifiers

Clean air is part of a comfortable dental visit, and HEPA air purifiers are one of the simplest ways a dental office can support that. At Dental Office of Dr. Salm, Kanner, and Grandeau in New York, NY, hospital-grade purifiers run in the treatment rooms to help keep the air you breathe during your appointment as clean as possible.

What HEPA Air Purifiers is

HEPA stands for High-Efficiency Particulate Air, a filtration standard that captures a very high percentage of airborne particles as they pass through a filter, including dust, pollen, and fine aerosols. Unlike a basic fan or a standard furnace filter, a true HEPA filter is designed and tested to trap particles down to a very small size, which is why HEPA units are widely used in medical and dental settings where air quality matters.

In a dental office specifically, treatment naturally generates fine aerosols and spray from handpieces, ultrasonic instruments, and polishing tools. HEPA purifiers are placed in the room to continuously draw air through their filters, reducing the amount of these particles that linger after a procedure. This is an addition to, not a replacement for, the suction and ventilation already built into a modern treatment room — it works alongside those systems rather than instead of them.

How we use it at Dental Office of Dr. Salm, Kanner, and Grandeau

Our hospital-grade purifiers run in the treatment rooms throughout the day, filtering the air continuously rather than only when a specific concern arises. They work in the background alongside instruments like our ultrasonic scalers, electric handpieces, and high-powered suction — tools that are part of routine cleanings, fillings, and other everyday procedures and that can generate fine spray during use.

Because the purifiers are simply part of the room setup, they don't require any special appointment or preparation on your part. Whether you're in for a routine cleaning, a restorative procedure, or a longer visit involving a soft-tissue laser or rotary endodontic instruments, the air purification is already running quietly in the background.

What it means for you

For patients, the main benefit of HEPA filtration is straightforward: cleaner air in the room you're sitting in for the length of your appointment. This can matter to anyone, but it may be of particular interest if you're sensitive to airborne particles or simply prefer added reassurance about the environment during treatment.

Because the filtration runs continuously rather than being switched on for specific procedures, it's a passive layer of comfort rather than something you have to ask for or plan around. It's one more detail, alongside things like noise-canceling headphones or nitrous sedation for anxiety, aimed at making the overall visit feel calmer and more comfortable.

What to expect during your visit

You won't need to do anything differently to benefit from the HEPA purifiers — there's no separate step, form, or scheduling involved. When you're seated in the treatment room, the unit is already running quietly, filtering the air as your appointment proceeds, whether that's a short cleaning or a longer procedure.

During treatment, you may hear a low, steady hum from the unit, similar to a quiet fan or air conditioner. It doesn't interfere with instruments, conversation, or any other part of the visit. Afterward, the purifier continues running as the room is prepared for the next patient, helping the air clear between appointments.

Frequently asked questions

Is HEPA filtration safe?

Yes. HEPA filters work purely by physically trapping particles as air passes through them; they don't add anything to the air or use chemicals. They're a standard, well-established technology used across medical and dental settings.

Will I notice the purifier during my appointment?

You may hear a soft, steady hum, but it shouldn't be distracting or interfere with your treatment. Most patients simply notice the room feels comfortable and don't think about the unit at all.

How often does the purifier run?

The units in our treatment rooms run continuously throughout the day, not just during specific procedures. This means the air is being filtered whether you're in for a quick check-up or a longer appointment.

Is this relevant for every type of visit?

Yes — because the purifiers run continuously in the treatment rooms, they're part of the environment for routine cleanings, restorative work, and longer procedures alike. There's no separate category of appointment where they apply.
