Types Of Air Purifiers: Guides To Pick Your Right Air Purifier

There are several types of air purifiers available on the market today. The types of air purifiers can usually be distinguished by the type of filter or filtering system they use. Note, too, that your choice in picking the right purifier for you will depend on your specific needs.

Below are the 6 most common types of air purifiers according to their functions:

HEPA Technology

HEPA filters use a fine fiber type of filter system that’s designed like an accordion. Since pollutants need to go through several layers of filters, even small particles can be caught in the system.

Air purifiers that use True HEPA technology are known to be the most effective of all HEPA filters.

This type of filter is proven to be effective in trapping up to 0.3 micron-sized particles at 99.97% efficiency.0.3 micron-sized particles are really very small, as the human eye can only see up to 10 microns.

Some examples of particles and pollutants that are 0.3 microns include the following:

  • Smoke particles
  • Pollen
  • Pet Dander
  • Mold Spores

When an air purifier is equipped with a HEPA system, a fan system will suck pollutants and contaminants from the air and push these particles through the HEPA filter. Clean air will then be released back into the room.

HEPA Filters can either be replaceable or cleanable.

Replaceable HEPA Filter – If you get a unit with a replaceable HEPA filter, you will need to get a new one when the filter is already worn out or dirty. Your air purifier will be useless if you use a dirty filtering system since air will no longer be able to force pollutants through it (because it’s already full of dirt and contaminants).

So, before getting a model with a replaceable HEPA filter, know that the lifespan of the filter will last anywhere from 6 months to 5 years (depending on use).

Cleanable HEPA Filter – A cleanable HEPA filter can be washed, so you don’t need to buy a new one every time it gets dirty. This type of filter will usually last as long as the air purifier itself.​

You will know that you need an air purifier with a HEPA technology if you are after a model that’s effective in filtering the air from airborne particles. A HEPA air purifier is most effective for the following:

  • Allergens (pet dander, pollen, mold spores, etc.)
  • Dust
  • Pet hair

Clean Dust

Note, however, that a HEPA filter is not that effective in purifying the air from the following pollutants:

  • Chemical fumes
  • Odor
  • Germs

Since a carbon filter can eliminate the above-mentioned pollutants, it’s often used in conjunction with a HEPA filtering system.

Activated Carbon Filter Technology

Activated carbon and activated charcoal are often used interchangeably because they have similar nature and functionality. These two basically carry the same element structure as they both come from carbon mineral.

Both activated carbon and activated charcoal are made from porous materials that can burn. They are both capable of absorbing pollutants in the air as well.

When given the option to choose between activated carbon and activated charcoal, I would suggest going for the activated carbon filter. Just look at their comparison below and you’ll understand why.

  • Activated Carbon – Since an activated carbon filter is designed to have a large surface area, it’s more efficient than an activated charcoal filter.
  • Activated Charcoal – An activated charcoal can be considered to be inferior to an activated carbon because of its consistency and design. In fact, 3 pounds of raw charcoal is equivalent to 1 pound of activated carbon.

Still, both activated carbon and activated charcoal filters are used in air purifiers their molecular structures allow them to be very absorbent.

Listed below are just some of the pollutants and contaminants that carbon filters can effectively absorb (these are trapped in the filter and are not released back into the air):

  • Smoke – cigarette smoke, cooking smoke, etc.
  • Odors – all types of odors (cooking odors, smoke odors, food odors, etc.)
  • VOCs such as the chemical fumes released when you use household cleansers.
  • Chemical emissions (such as formaldehyde – which are found in carpets, upholstery, wood paneling, etc.)

When considering getting an air purifier with a carbon filter, however, note that it’s not very effective in purifying the air from the following:

  • Allergens (pet dander, pollen, mold spores, etc.)
  • Dust
  • Pet hair

If the above-mentioned pollutants are also your main concerns, get a model that has both carbon and HEPA filters. click here to know more about the powerful air purifier for cigarette smoke.

UV Technology

What is UV Air Purifier? When an air purifier is using UV technology, it means that it’s equipped with a UV lamp. The radiation from the UV lamp will cause cellular and genetic damages to microbes so as to kill and destroy them.

UV technology can, therefore, be your chosen type of air purifier if you’re dealing with the following:

  • Germs
  • Bacteria
  • Viruses

Please know that UV radiation is not effective in the following types of air pollution:

  • Airborne particles
  • Smoke and smoke particles
  • Odor

Although effective against pollutants and contaminants, its limitations make UV light inefficient in thorough air purification. Because of this, this type of filter is best combined with other types of filtering systems.

But don’t worry – there are lots of air purifiers today that carry multiple filters for a multi-stage filtering system in their design. click here to buy some uv air purifier.

Negative Ion Generator

Negative ion generators, which are also called ionizers, release negative ions into the air. With this system of air purification, the negatively charged ions attach to airborne pollutants which are positively charged.

As airborne particles become heavy, they will stick to surfaces or fall to the ground.

Here are just some of the pollutants that a negative ion generator can be useful for:

  • Pollen
  • Fine particles of dust
  • Smoke particles

So, yes, ionizers are also useful as air purifiers – so you can also consider getting them when looking out for an air purifier. However, note the following points (disadvantages) below:

  • Releasing negative ions in the environment will not really clean the air from airborne pollutants – these will just be removed from the air.
  • When left uncleaned, pollutants that have been brought down to the floor can be stirred up again (such as when you walk on them unknowingly).

Ozone Generator

As you can already tell, an ozone generator produces ozone – which is a type of toxic gas. Ozone can cause the following health problems:

  • lung irritation
  • breathing problems
  • long term respiratory ailments

Asthma Sufferers

Note that exposure to ozone gas can only be considered safe if it’s within the set limit on public health standards. When inhaled in levels that are higher than the set standards, this can cause very serious health problems.

While ozone generators are effective as ozone air purifiers, therefore, they are only recommendable for shock treatments. When a room is treated with this type of air purification, it can be cleaned from the following types of air pollution:

  • Odor
  • Odor-causing molecules
  • Germs
  • Bacteria
  • Viruses

Unlike the HEPA filter, however, an ozone generator is not effective in cleaning the air from the following:

  • Dust
  • Pollen
  • Pet Dander

Anti-Bacterial Filters

Anti-bacterial filtering systems include the use of anti-microbial coatings that are applied to an air purifier’s main filter. Typically, anti-microbial treatment is applied on HEPA and carbon filters to kill microbes on contact (as these are trapped in the unit’s filters).

Anti-Bacterial filters are therefore effective in cleaning the air from disease-causing germs such as the following:

  • Bacteria
  • Viruses
  • Microbes

While this type of filter is not usually used as the sole filtering system in an air purifier, it can surely improve the performance of other types of filters.

Which is Filter Type the Best Air Purifier for You?

If I were you, I would get an air purifier that’s equipped with a multi-stage filtering system. No, a model with different types of filters is usually not that expensive because you will be getting them in a single package.Your air purifier can have the above filters.

lWith such type of air purifier, your indoor environment can be effectively purified from different types of air pollutants, contaminants, and disease-causing germs, right? For practical reasons, however, choose a model that carries separate controls for the different types of air-filtering systems.

This way, you can turn a filter feature on and off as needed.So, here’s to a healthier environment and a healthier you! Now that you know the different types of air purifiers, you can surely get the model that’s right for you.
