How Do Air Purifiers Work?

It seems too good to be true that a device can remove 99.9% of germs in your household without making a sound. However, air purifiers do exist, and they’ve become much more of a necessity with the rise of airborne diseases.

Air purifiers work by absorbing the surrounding air, pushing it through a filter, and releasing clean air into your house. A traditional home air purifier is going to need an air filter. These filters catch and remove pollutants, allergens, and other particles.

Why You Should Get an Air Purifier

The best air purifiers will not only make your air cleaner but make it easier to breathe around you. If you struggle with asthma or have other lung-related health issues, air purifiers can help you breathe softer and healthier air. You can also purchase an air purifier for allergies.

Do you have plenty of children at home? Are you housing a newborn? Air purifiers will ensure indoor pollutant removal, so your children aren’t exposed to harmful particles.

Advantages of Air Filters

Almost every traditional air purifier is going to come with an air filter. Besides reducing airborne diseases and pollutants, other benefits of air filters include:

  • Improving sleep quality
  • Reducing dust, mold spores, and pet dander
  • Neutralizing home odors

Disadvantages of Air Filters

The main disadvantage of air filters is the costly maintenance. You should replace your filters every month or up to a year, depending on what type of filter system you have. These filters can cost as high as $200.

When it comes to purchasing the best air purifier, research companies that are filter-free, such as Airfree, so you can save the trouble.

Best Air Filter for Your Air Purifier

Most air filters differ in maintenance requirements and how they filter pollutants. To find the best one for you, look into the following filters and choose what fits your needs.

HEPA Filter

HEPA filters are the most common air filters found in traditional air purifiers. HEPA stands for “high-efficiency particulate air”; this filter is known for removing up to 99.97% of dust, mold, bacteria, and other airborne particles. They last up to one year, depending on how often you use your air purifier.

HEPA filters work by pushing air through a mesh that traps pollutants. As long as your air filter is large enough, HEPA filters will remove the majority of harmful particles in your household.

The only disadvantage to HEPA filters is that they aren’t 100% guaranteed to work. These filters cannot remove particles that are too small to absorb. For instance, your HEPA filter won’t help neutralize smells such as ammonia due to their tiny particle size.

Carbon Filter

Carbon filters are more helpful when it comes to getting rid of household odor. A carbon filter will last you around six months, but the increased maintenance isn’t so bad when you have reliable pollutant removal.

Carbon filters trap odors against an outside surface. As air flows through the filter, carbon acts as a bodyguard against harmful pollutants. These particles become trapped while the clean air pushes through.

This filter’s advantages lie in its natural filtering process. You don’t have to worry about the use of chemicals or substances to increase filter effectiveness. Instead, carbon filters are low-cost, easy to maintain and neutralize potent odors such as chlorine.

The disadvantage of carbon filters is that it doesn’t remove dust. If you’re looking for an air purifier for allergies, you should stick to another filter. Carbon filters are also not as effective in eliminating microorganisms as the HEPA filter.

Ionic Filter

Negative ions release into the air when you’re using an ionic filter. These ions attach to contaminants and deactivate them. This filter is best for people looking to remove smoke or similar toxic fumes.

A con of ionic filters is that they release ozone when in use. Ozone consumption can result in asthma triggers or cause lung damage.

Additionally, this air filter doesn’t remove particles from your house. Once the pollutants deactivate, they fall to the ground. This can cause the particles to go back into the air with time.

Ionic filters are more helpful for filtering smoke rather than airborne diseases.

Washable Filter

A washable filter will save you money in the long run, as long as you have more time!

You’ll be changing these filters almost every month, depending on the number of pollutants in your home. Washable air filters are electrostatically charged to attract toxic contaminants. Once the filter is full, it’s up to you to clean it.

These filters are eco-friendly because they are reusable. However, washable filters are less effective against indoor pollution.

Most filters properly get rid of dust. However, washable filters fall flat when it comes to removing bacteria or pet dander.


Pre-filters are primarily used with other filters, such as the HEPA. They act as a preventative step against larger particles, like dust and hair, so they do not clog your primary filter. A pre-filter needs to be washed and changed every three months.

By itself, a pre-filter won’t do much for your home air purifier but extend its lifetime. Pre-filters ensure your primary filter protects against debris, so they are a great addition if you want to sustain your air purifier.

Can You Purify the Air Without the Filter?

Filteration has become essential to promote worldwide public health, down to our furry friends. With the discovery of so many different forms of air pollution, there has never been a better time for filtration to clean up.

Air and water purifiers sustain your health and the quality of life through household pollutant reduction. But not everything is as perfect as it seems. Almost all appliances require constant replacement of the air filter.

This can make finding the best air purifier harder than you think.
