Clean and fresh air in school, study area, and classrooms protects the students from germs and bacteria and increases productivity and performance. The best and easiest way to purify the indoor air is to have the best air purifier for classroom with high-quality air filters.
The classroom air purifiers protect the students and teachers from seasonal allergies and toxic elements in the air like smoke and volatile organic compounds. Moreover, they filter out dust, mold, spores, and other allergens within few minutes of working.
Before buying an air purifier for the classroom, ensure that it has a True HEPA filter and Activated Carbon filter. Some air cleaning machines also have Ionizers and UV-Light Sanitizers, which are also best for killing germs, bacteria, and viruses. But these ionizers and UV-Light sanitizers can be problematic for asthma sufferers.

Photodan70 reviewed IQAir HealthPro Plus on Amazon and shared his experience,
This machine really cleans the air! Yes it is louder on full blast, but it supposed to! AIR is moving quickly through the machine so no it wont be silent as some seem to want? As far as the carbon removing the smell in the air, I can say it does wonders. In fact, it cleaned so well that one day when I smelled smoke I realized that the air was so clean that I smell residual smoke on the things around me… the couch, the walls etc. The filters are expensive but after years of wasting my money on supposed air filters, I don’t have to waste anymore. The only thing I run the old cheaper air cleaners for is to catch errant cat dander so I don’t have to dust as much. One downside is, because of having to push air through three filters at high rate it uses the most electric of my air filters. But thats because it is doing what it supposed to so I will deal with it. One other wonky thing is the remote… you’d think you just point it at cleaner to work but you don’t. The sensor is on TOP of the unit so you sorta have to bounce signal off the ceiling for the cleaner to get it. But again no big deal. I was not paid for this review… I have had it for three weeks,. Ps, you HAVE to sign for it and sometimes it arrives early! Sign up for Fedex notifications so you know when to be home! Just a tip
