The classroom, regardless of the age of the students, is a place where there is a lot happening all the time. Because of the close proximity of students and teachers to one another, it is also an environment where germs can spread easily from one person to another.
The renovation of many schools in attempt to make them more energy efficient often affords less opportunity to exchange the air or control the temperature. Taking matters into your own hands by filtering the air with a portable air cleaner is a low-cost but effective way to make sure the air you and your students are breathing is as fresh and healthy as possible.
By avoiding the following 5 features in a purifier, you can insure that you are getting the most effective cleaner for your room.
High Maintenance---Like needy people, an air purifier that requires lots of constant attention to work efficiently can be a real drain. Avoid a cleaner that needs you to wash, spray, recharge, or otherwise go inside the unit to handle the filter at all.
Instead, opt for a unit that does not require you to go inside unless you are replacing the old filter with a new one. The most your cleaner should need from you, and only if you choose, is to vacuum the outside of the unit with a small, portable, hand-held vacuum once a week.
This maintenance is aesthetic because it makes the unit look nicer by removing large particles that might be showing on the outside of the unit, and vacuuming will also pull particles away from the first filter inside the unit. This will prolong the life of the other filters inside the unit.
Short Filter Life---A purifier that requires filter changes every 6 months or yearly increase the cost to operate the unit by a lot, and is also expensive in terms of time spent ordering and replacing the filter.
Two things will help. Choose a unit that has filter with a life of 5 years. And choose one that has warranty so that if it doesn't last that long, you get a price that is greatly reduced on the replacement.
One Filter Unit----Scan the technical specifications and/or owner's manual on any unit you are considering. If it says there is only one filter, run from it! One filter cannot possibly remove particulates, gases, chemicals, and odors. And you need a cleaner that can remove all of those.
Look for a cleaner that has filters for both particles (a HEPA or high efficiency particle arresting filter) and gaseous pollutants (carbon). With both types of filters your unit will be able to eliminate particles that range from the visible to microscopic, and can also eliminate gases, odors, and airborne chemicals.
Rigid Placement Requirements---Classrooms aren't always the most spacious places in the world. So if a cleaner requires that it be placed in the middle of the room to work effectively, it's a poor choice for your room.
A cleaner with 360 degree intake can be placed in a corner, by the wall, or anywhere else you need it to be as long as there is about 6 inches of clearance on all sides. This gives you the option of tucking it out of the way and still enjoying the benefits of effective filtration.
Limited Daily Operation---The pollutants in your room don't take a break, and the cleaner you select shouldn't need to take one either. If you are considering a unit that can only operate for a limited number of hours during a 24 hour period, it's not the one you need.
The motor on your cleaner should be a split capacitor motor that is designed to run 24 hours a day every day. This means it can run whether you are there or not. Being able to allow it to run 24 hours day insures that each day in your room literally starts as a breath of fresh air.
