Filtering the air in the classroom goes a long way towards keeping everyone healthy throughout the year. But all classroom air purifiers are not created equal. In order to be effective the unit should have the following 5 features.
Maximum Effectiveness With Minimum Maintenance—The classroom is a busy place and the best unit to have is one that will take care of you and your students without a lot of maintenance. It should not require that you spray, clean, charge or handle the filters in any way other than when they need to be changed. And changing the filter should only be required every 5 years.
Quiet –The operation of your unit should not be so loud that it discourages you from using it all the time. The drone of a motor all day every day can be tiring, and for many students a distraction. The unit you choose should be quiet without any sound other than that of air.
Continuous Cleaning–The most important goal for filtration is to keep the air quality high all the time by continually filtering out airborne particles and gaseous pollutants that can cause problems for healthy students and exacerbate pre-existing respiratory conditions like allergies and asthma.
Being able to rely on purification 24 hours a day will require that the unit contain a split capacitor motor. This type of motor is designed for continuous and high revolutions per minute. It is important to confirm that the cleaner has this type of motor by looking in the technical specifications. Without this feature many units can only be operated for a limited number of hours each day in order to preserve the motor and keep the unit operating.
Avoids Controversy—Fresh air should be the only by-product that a classroom cleaner (or any unit produces. Cleaners that produce any amount of ozone and ionized particles continue to get mixed reviews about the effects they have on humans. There are also questions about how effective they are at cleaning the air.
HEPA And Carbon Filtration—HEPA or high efficiency particle arresting filtration is designed to remove 99,997 out of every 10,000 airborne particles that are.3 microns or greater in size. This means it can remove dust, pollen, pet dander, mold and mildew spores, and bacteria and viruses that generally attach to these bigger particles.
Having a filter that has activated carbon gives the cleaner the ability to remove gaseous pollutants and can include odors from cleaning solutions, paint, wax and a lot of others odors that you can't quite identify.
This kind of filter increases your chances exponentially of walking into a classroom each morning that is fresh, healthy, and inviting to you and your students. And setting a healthy atmosphere is half the battle won.
