Dental Clinics and Air Changes Per Hour

We have customized an indoor air quality assessment and indoor air quality audit for dental offices to meet CDC, RCDSO and ODA requirements for current and post COVID-19 patient care.

According to the Royal College of Dental Surgeons of Ontario all dental clinics will need to know their Air Changes Per Hour and have an assessment performed of airborne particulate if they do not wish to wait 3 hours in between dental procedures.  On May 31, 2020 this was changed to just positive COVID-19 patients.  But what about ASYMPTOMATIC PATIENTS?  Most people who contracted the coronavirus didn't know they had it before they showed symptoms or never showed symptoms at all.

Protect yourself, your staff and other patients.  Know your ACH and install the right HEPA equipment.

Air Changes Per Hour is different for every indoor environment, every building and every clinic.  Only a designated ACH audit will determine your Air Changes Per Hour of your treatment room or area.  Mechanical or HVAC plans and schematics don't show your actual airflow coming from each vent.  You could be mistakingly be calculating the wrong ACH.  Only testing of each vent will show you the actual air flow to properly determine ACH in each treatment area.

Some clinics don't need HEPA filters at all depending on the CFM from their ventilation system.  Other clinics need HEPA and exhaust systems...it all depends on how much airflow you already have.

If you already have HEPA filter equipment, we can test these devices to make sure they are actually filtering at a 99.97% efficiency at 0.3 microns.

Don't guess with your health...We can show you if your HEPA equipment is working and help you make the right decision in what brand and size of HEPA you should be buying.

The CDC Guideline for Airborne Contaminant Removal defines the amount of time needed in between patients depending on Air Changes Per Hour (ACH) of your specific treatment or operatory.  

We can help you minimize down time in between patients.
