HEPA Air Purifier for Classroom: Create the Safest School for Students
Air quality in classrooms is crucial to the health and safety of teachers and students who spends nearly eight hours in the classroom every day. A classroom usually holds 20 people, which is a perfect environment for the spread of viruses and bacteria.
Poor indoor air quality can lead to mental health issues, such as cough, sneezing, runny nose and other respiratory problems. Students are more sensitive to airborne diseases. In this case, their attention and expression will be affected and they will not be able to devote themselves to learning.
That's why you should get an air purifier for classrooms.
The air purifier is the simplest and most reliable method to improve air quality in classrooms. Air purifiers use a filtration system to effectively remove air pollutants, such as mold, bacteria, dust mites, pollen, harmful chemicals and other allergens.
What we are here to answer:
When choosing air purifiers for the classroom, here are factors you need to consider: filters, noise level and CADR.
The type of air purifiers is related to the purification efficiency and safety. You should pick HEPA air purifiers, and avoid air purifiers producing ozone such as ozone generators, UV air purifiers and ionizers.
The HEPA filtration is the most effective technology to purify the air without additional health risks for students or teachers when operating in school classrooms.
Students need to study in a quiet environment, so the noise level of the air purifier should also be taken into account. Choosing an air purifier with adorable noise at the highest speed won't disturb the class time.
Another thing to consider is the CADR of air purifiers. CADR indicates the volume of filtered air an air purifier delivers per hour. It shows how quickly an air purifier is able to remove dust, pollen, viruses, and bacterial in classrooms. You should pick an air purifier with CADR meeting the area of the classroom.

After you invest in an air purifier, the next thing to consider is the placement of the air purifier. Check following suggestions to maximize the efficiency of air purification of the equipment:
The air purifier draws in air from all directions, so you should place the air purifier as close to the center of the classroom as possible, which will maximize the amount of air passing through the HEPA filter. This ensures that everyone in the classroom can breathe clean air.
Don't place it in a corner. It can't work effectively without proper airflow. The airflow in the corner is the lowest. The air purifier may work, but it can't purify the air in the whole classroom.
You need to put the air purifier in an open place of the classroom, make sure there are no obstacles around it, and keep it at least three feet away from other objects.
Keep the air purifier away from multimedia devices because they may be affected by radiation.
Do not put other objects on the top of the air purifier, which is not conducive to its release of purified air.
Use the air purifier with open windows to enhance natural ventilation.
Make sure that the equipment is placed in a location where it will not fall onto someone, especially students. You also need to fix the wires to prevent tripping hazards.

The truth is that no air purifiers can prevent the COVID-19. The size of COVID-19 is varied from 0.06-0.14 microns, while HEPA air purifiers can only capture particles larger than 0.3 microns.
Air purifiers can help reduce pollutants in the air, including common viruses and bacteria. However, air purifiers alone are not enough to protect you from coronavirus disease.
Using air purifiers may be a way to reduce the risk of contracting COVID-19, along with other measures such as wearing masks, keeping social distance and using hand sanitizers.
It should be noted that although ozone is effective against viruses, ozone generators are not enough to kill coronavirus when the concentration of ozone does not exceed the public health standard.
Moreover, as we have mentioned in the previous article, ozone can cause harm to the human body. It is not recommended to use ozone generators or air purifiers producing ozone in classrooms.
