Air Purifiers for Schools

Post by Sharp Hygiene

It is common knowledge that the quality of air that we breathe has a direct effect on our health and well-being.   As part of the Covid-19 response plan, The Department of Education has laid out clear guidance for the use of room air cleaners in schools and creches where poor air quality still exists.

Irish Department of Education Guidelines for HEPA Filter Air Purification

“Air cleaners can assist in removal control and provide an additional measure of precaution where poor ventilation exists. They should not be used to fully replace ventilation and should be used in conjunction with and to support other methods of ventilation that are available “

Full details of the minimum specification for HEPA Filters Air Purification can be found here.

In short, the Air Purifier must

  • Have a HEPA Filter with a certification of 13 or 14
  • Comply with EN1822
  • Change the air in the room at least 3 times in one hour
  • Not be too noisy

How to choose your Air Purifier?

When researching air purifier units, it is essential that you choose a unit that can fully clean all of the air within the room.  This is referred to as ACH (Air changes per Hour). To select the correct unit for your room, you will need to calculate the volume of your room.

Most air cleaners are labelled with a rate for CADR (Clean Air Delivery Rate). You can calculate the air changes per hour by using the below equation.

Depending on the size of the room you may require more than one air purifier to meet the requirements set out by the Department of Education – Three Air Changes Per Hour.

Once you have found a unit that is suitable for your requirements, it is a good idea to check the life span of the filters within the Air Purifier and that the filters are readily available.
