We provide advice on which air purifier is best for a classroom environment

Air purifier For The Class

The classroom is where your children spend much of their time. It is imperative to create an environment that maintains a clean and healthy air quality. This list of the best air purifiers for classrooms will provide you with all the information you need in order to properly purify the air at your child's school.

Improving air quality in schools is a very important issue. This is because kids spend most of their time in the classroom, and too many of them suffer from airborne diseases that can be alleviated through proper air purification. This problem is much more significant than you might imagine.


The Cause of Poor Air Quality in Schools

Since kids spend the vast majority of their time in school, it is more likely than not that they will get sick at some point. According to research, about one third of all school children will suffer from a respiratory infection during the course of a school year.

The main culprit behind this illness is poor air quality. Children are very sensitive to airborne pollutants and allergens because their immune systems are still developing. When their respiratory systems are bombarded with dust, mold spores, bacteria and viruses on a day to day basis, it becomes much easier for them to develop an infection.

Science behind poor air quality in schools

A classroom can be home to a lot of different viruses, bacteria and allergens. A school building that is not properly maintained is the perfect breeding ground for these types of microorganisms. For example, you might have dust mites living inside the cushioning of your child's chairs.

These little bugs are barely visible to the human eye and they feed on dead skin cells. They also spread out a very strong allergen which causes many people to develop allergies. Just one of these bugs can cause an allergic reaction in susceptible children, which can lead to serious respiratory complications.

Should I put an air purifier in my classroom?

The unfortunate truth is that airborne infections are widespread in schools. The EPA (Environmental Protection Agency) has stated that 10% of all schools have a mold problem. These are incredible statistics considering the fact that rats and other pests can transfer dangerous diseases to humans.

In addition to that, schools are very humid places since they usually have high temperatures and relatively low air circulation. This combination of factors increases the prevalence of mold growth, which is not something you want in a classroom where impressionable children spend most of their time.

Do air purifiers help with Covid in a classroom?

Yes, air purifiers are excellent at eliminating airborne contaminants. In fact, they are so effective in doing so that the EPA recommends using them to prevent the spread of airborne illnesses in schools. This is especially true since air purifiers can remove contaminants from the air to which children are constantly exposed on a daily basis.

For example, an air purifier with a hepa filter will eliminate odors and allergens such as dust mites, pet allergens, bacteria and viruses from the indoor air.

Improving Indoor Air Quality in Your Child's School

In order to create a healthy indoor environment at your child's school, you must take measures to improve the quality of your child's classroom environment. Proper maintenance is essential for this purpose. For example, you might be aware that kids are highly susceptible to airborne viruses and bacteria.

You can use an air purifier in your classroom to ensure that these microorganisms are kept at bay. You can also use an air purifier to eliminate harmful volatile organic compounds (VOCs) that could potentially harm your child's health.

Why is clean air important?

If your child's school has a mold problem, then the likelihood of them developing allergies or asthma will increase. This is because your child will be exposed to mold spores all day long, which can cause them to build up an immune response to the allergen.

Those who suffer from asthma can experience an increased sensitivity to pollen and other allergens, which could cause their symptoms to flare up and worsen.

Anyone who suffers from respiratory illnesses should have access to clean air at all times, since it helps reduce their symptoms and increase their quality of life. However, this is especially true for children whose bodies are still developing. Indoor air pollution can affect the respiratory tract, nasal passages, throat and lungs directly.

Air purifiers can help you to avoid health related issues

In order to maintain a healthy environment at your child's school, you must keep the air in your classroom clean. In order to do this, you will need an air purifier that will remove harmful microorganisms and VOCs from the air. However, it is important to note that these indoor air purifiers can be used in homes as well as schools.

While you might be tempted to put a permanent air purifier in your child's classroom, you should remember that it is always better to be proactive about improving the quality of your kid's environment.

They can help you to improve the overall air quality in the classroom

The good news is that your child's school is a perfect environment to use an indoor air purifier. If you put an indoor air purifier in the classroom, then you will be able to improve the quality of air that your child breathes. In addition to that, an indoor air purifier can reduce airborne pollutants such as dust mites and bacteria.

What To Look For In An Air Purifier A Classroom

When purchasing an air cleaner for a classroom, there are a few things you need to keep in mind. The first thing is that the air purifier you choose must be of good quality. It should also be able to capture particles such as dust, pollen and other airborne allergens.

Although it might seem like air purifiers are only meant to remove smog and smoke, they can actually serve as a very effective tool for removing airborne pathogens.

Ease of Use:

Ease of Use is the most important thing to look for when shopping for an air purifier. Many of the large-scale air cleaners have complicated features that you need to read up on in order to set them up properly. Fortunately, the products on this list are very easy to use. All you have to do is install it in your classroom and plug it in.

Power settings:

Power settings are a very important part of the air purifier. Make sure that you look carefully at the power settings that are available on the different products on this list. It is also important to distinguish between low, medium and high settings.

For example, it is possible for an air purifier to have both a low and medium setting which will result in inconsistent results. As such, it is best to go with either a lower power setting or a higher power setting if possible because it will be more consistent across the board.

Air Cleaner (Fan):

Air Cleaner is another important feature to look for in an air purifier. There are two types of air cleaners that you can choose from. The first type is the standard fan which will push air around the room and into your child's lungs. The second type of air cleaner is a vaneaxial fan, which will create a vortex that sucks in more particles of dust and other airborne particles.

Air Filters:

Air Filters are another important aspect of an air purifier. The reason that air purifiers are so effective has to do with the quality of their filters. It is essential for the air purifier to have a high-quality filter that can trap airborne particles and even allergens such as dust mite feces and animal dander. This will ensure that your child is breathing in fresh and clean air throughout the day.

Types of Air Purifier For A Classroom

There are a number of different air purifier options available to you when it comes to creation an air purifier for your classroom. Let's take a look at some of the different types of air filters and then focus on the different types of purifiers that are available today.

HEPA Filters:

HEPA Filters are some of the most efficient air filters on the market today because they can trap 98% of all airborne particles. HEPA filters are very efficient at removing bacteria, viruses and even allergens that are floating around the classroom.

Electrostatic Filters:

Electrostatic Filters can be found on a lot of air purifiers on the market today and they are one of the most popular types of filters to use. The reason for this is because electrostatic filters can collect a wide range of particles including pollen, fibers and other pollutants. They can also work on very small air particles without causing too much disruption to your child's breathing.

Activated carbon / Charcoal filters:

Charcoal filters are proven to be one of the most efficient and powerful filters on the market today. They are capable of trapping a wide range of different airborne particles, including pollen, mold spores and other pollutants. This means that you will breathe in clean and healthy air every time your child comes into contact with an air purifier using charcoal filters.

Ultraviolet (UV) light :

Ultraviolet light can be used as an alternative to other air filtration methods. According to research, UV light can be effective at killing airborne pathogens before they enter your child's throat and lungs. This minimizes the chances of infection and illness in your child due to poor air quality in the classroom.

Type of Pathogen In An Air Purifier For A Classroom

There is a wide range of different airborne contaminants that can cause discomfort and even heat related illnesses in your child. The most common pathogens found to cause respiratory problems include bacteria, viruses and mold spores.


Bacteria is one of the main causes of respiratory problems experienced by children in schools. Bacteria is also known as gram positive or aerobic bacteria because it thrives just as well in oxygen-rich environments such as a school environment. Bacteria thrives in conditions of low light or no light at all. As such, it is very important to make sure that your child's air purifier can kill bacteria and other pathogens found in the air.


In many cases, viruses are responsible for things such as Strep throat and even allergies. These are some of the most common causes of illness among children in schools. Viruses are also known as gram negative or anaerobic bacteria are extremely challenging to kill. As such, it is very important to use an air purifier that includes anti-viral agents in its design.

Mold Spores:

Mold spores are known to be a very common cause of respiratory problems among young children. The main reason for this is because mold spores can cause allergic reactions that affect your child's nasal cavity and throat. Mold spores are also known as absolutely aerobic bacteria because they require oxygen to thrive.

As such, it is very important to make sure that your child's room has an excellent air filtration system that can trap mold spores before they enter your child's mouth and lungs.


Allergens are a very common cause of chronic illness among children in classrooms. Some of the most common allergens include dust mite feces, pollen and animal dander. As such, it is very important to make sure that your child's classroom has a high quality air purifier that can trap these allergens before they enter your child's respiratory system.


Pollen is a very common cause of illness among children in classrooms. It is estimated that roughly 30% of all respiratory conditions can be attributed to pollen and other allergens in the air. As such, it is recommended to use an air purifier when your child spends time inside a classroom setting.

Dust mites.

Dust mites may be one of the most common allergens found in classrooms. As such, it is recommended to use an air purifier that includes an anti-mite agent so that your child can breathe in a cleaner and healthier environment whenever he or she is in school.


Smoke is one of the most common causes of asthma and other respiratory conditions among children in classrooms. As such, it is recommended to use an air purifier that includes an anti-smoke agent in its design so that your child can breathe cleaner and healthier air whenever he or she is in the classroom setting.


Odors are one of the main causes of respiratory problems among children in classrooms. For example, if a child belonging to another class smells fish, then your child may begin experiencing allergic reactions due to the odor.

As such, it is recommended to use an air purifier that includes an anti-odor agent in its design so that your child can breathe cleaner and healthier air whenever he or she is in the classroom setting (around kids with strong scents).


Many schools are not equipped with air conditioning, which means that there is very little airflow in the classroom. Students are often instructed to keep the windows shut, which traps all of those pollutants and allergens inside the room.

This is a particularly bad idea in places that experience warm weather during the day. The heat can make these pollutants much more aggressive and it can exacerbate many respiratory problems in susceptible kids.

Keeping your child at school is probably the wisest decision, but you have to take all of these factors into account when choosing an air purifier for your school. The best air purifier for classrooms will be able to absorb and neutralize most types of airborne pollutants.

It should also be able to filter out allergens, such as dust, mold spores and pet dander. In fact, there are a few models on the market that are specifically designed to filter out pet odors from the classroom. The choice is ultimately up to you, but these products have proven themselves many times over.

Other Questions

Are air purifiers really worth it?

Yes, air purifiers are worth it. There are a lot of benefits associated with having an air purifier in your class.

One of the biggest benefits of owning an air purifier is cleaner air. A properly operating air purifier goes a long way in improving the quality of the air in your home or place of work. This will reduce the chances of you suffering from chest infections and allergies caused by airborne contaminants such as dust, pollen and pet dander.

Another reason why you should invest in an air purifier is its ability to remove bad smells that may be circulating around your class. Bad smells can be prevented or neutralized by using an air purifier fitted with anti-odor technology.

How long does it take for an air purifier to clean a room?

Every room has its own individual requirements and it is important to find the right air purifier in order to achieve the maximum results.

An air purifier placed on a table or desk will require more powerful filters than one placed in a corner of a room. This is where you need to check out the filter life of the air purifier model you are interested in. The longer the filter, the cleaner the air will be since it will be able to eliminate harmful airborne particles over a longer period of time. A common type of filter lives for about 3 months.

What is acceptable indoor air quality?

The air in your class is bound to contain some level of airborne contaminants that may be affecting your children's health. If you have more sensitive members of the family, it is better to keep them out of the class for health purposes.

Indoor air quality monitoring can be done in one of two ways. The first way is by checking the levels of airborne particles detected by a sampling device coupled with air monitors that can actually measure the particles levels in real-time. The second way is by taking samples from the air in a room and testing for any harmful substances that may be present.
