Five Most Common Types of Air Purifiers
There are quite a lot of different kinds of air purifier out there, especially as technology evolves, people rapidly discover more ways to build one. Though the following are the most common ones, you will see on the market.
HEPA – High-Efficiency Particulate Air
To be classified as an authentic HEPA, a filter needs to be able to filter at least 99.97% of particles above the size of 0.3 microns. However, the actual percentage is very dependent on what the related local authority dictates.
Hence, if you want to be extra sure of the efficiency of a particular HEPA filter, check out the place it was made or the authority that issues the HEPA approval. We don’t see the reason for doing so unless you need to be precise for a medical condition.
Most UV Lights air purifiers do come with a filtration system to trap particulates in the air just like any other standard filter. However, it is not what they are primarily used for. It is used to disinfect the air by altering the DNA of the viruses and pathogens and destroy them using UV lights.
Similar to other purifiers, Ionic purifiers are there to clean the air and reduce irritants in the air. However, silence is the most notable thing about them. They work without a motor inside. That’s why you do not have to hear the engine running sound.
However, the way they clean the air is a bit different. They shoot negative ions which will bond with whatever it is in the air that has positively charged ion (dander, mold, dust, etc.). As a result, those particles become heavier than the air and fall out of it.
Of course, they do have some shortfalls such as needing regular maintenance, and only suitable for a small area, but the pros are perfect for those with particular conditions. More details will be shown below in the products review section, so read on
Similar to the Ionic purifiers (these things emit positively charged ions though), but with the help of the HEPA technology, the electronic purifiers clean your air like no others.
The HEPA filter inside an electronic purifier will trap common air pollutants above the size of 0.3 microns. Then shoot positively charged ions into the air to zap whatever left that isn’t picked up by the HEPA filter.
Alright, we sort of feel like you might be getting a bit bored or wasn’t even interested in the science stuff in the first place. Hence, we will say what they are good and bad at.
An activated carbon air purifier is very efficient at removing gas-like irritants in the air. So, the stench in the air, smoke from a cigarette, and so on will be quickly eliminated at the cost of inferior efficiency of trapping other types of particles.

CHOOSING THE RIGHT FILTER TYPES
The classic Air purifier comes with a HEPA filter. Some may have other filters for specific needs, here are the terminology and definitions:
Pre-filter – An essential feature of air purifiers that use a HEPA style filter. The pre-filter captures large dust and pet dander to help prolong the lifetime of the main filter. Most pre-filters are washable and reusable and last a lifetime.
True HEPA Filter – This is the highest standard air filter you can get for a best air purifier. In order to carry this label, the filter must meet strict regulations set by the United States Department of Energy (DOE) and capture at least 99.97% of particles as small as 0.3 microns. A true HEPA filter needs to be replaced after 6 months to 1 year, and you should use a suitable replacement for your air purifiers.
Activated Carbon (or Charcoal) Filter – This filter can adsorb odorous particles and gases. That’s why it can remove the smells produced by smoke, pets, cooking, chemicals, etc.
Ionic Filter (or Ionizer) – This filter emits negative ions to charge small particles like dust, pollen and bacteria and collect them into a plate.
UV-C Light – The Ultra Violet light destroy bacteria and virus by sterilizing them. The UV-C Light (UV Light type C) is harmless to humans.
Advanced BioGS HEPA Filter – A technology from Rabbit Air, to help prolong the life of the main True HEPA filter.
Permanent HEPA Filter – A technology from Hamilton Beach, to make their HEPA-type filter be cleaned by vacuum, therefore you don’t need to replace their HEPA filter.
HEPA-type Filter – This filter is a lower quality version of a True HEPA filter and doesn’t meet the standards set in place by the U.S. DOE mentioned above.
CHOOSING THE RIGHT SIZE AIR PURIFIER
It is highly recommended to check your air purifier’s size and room capability. The size of an air purifier is varied, and if you do not have room for your new air purifier, it would be a disaster.
Room capability, or how well your air purifier can cover is also a crucial factor. You know, air purifier is not an one size fit all machine. Most air purifier is designed for a small room of 100 to 400 square feet. For a larger room, you will need an additional air purifier or larger coverage one. Otherwise your air purifier will not meet your demands, and cost you much more energy than normal.
KNOWING SOME TERMINOLOGY IN AIR PURIFIER
ACH stands for “Air Changes Per Hour”
The ACH rating, stands for Air Changes per Hour, tells you how many times the device can exchange the air within a room with clean, fresh air every hour. For example, 4X means the device cleans air four times per hour.
Common ACH ratings in best air purifier you’ll see are 4x, 5x, 6x, etc
Remember that the advertised ACH for air purifier is normally when you use the maximum fan speed.
CADR stands for “Clean Air Delivery Rate”
Developed by the Association of Home Appliance Manufacturers (AHAM), CADR, stands for Clean Air Delivery Rate, tells exactly how well an air purifier can clean the air within a particular size room.
For example, an air purifier with a CADR like this: dust/500 cfm, pollen/640 cfm, and smoke/500 cfm (or 500 Dust/500 Smoke/640 Pollen) will normally have a coverage from 700 to 800 square feet.
