The filter is the air purifier’s most essential element or technology. The filter is a mesh that traps hazardous germs and bacteria while allowing air to pass through.
The filters essentially clean the air, while the remainder of the machine handles the air inlet and output. The capacity of the blowers and filters to purify the air determines the intake and outflow rates.
That is all there is to it. To put it another way, you choose the filter and add-on features.
Air purifiers have shown to be a godsend in terms of improving air quality by reducing sources of pollutants. An air purifier eliminates impurities from ambient air and leads to a healthier living environment.
Families with children and babies, residences or workplaces in high-dust locations, construction zones, or along the roadway. Furthermore, if any of your family members suffer from asthma, allergens, or other respiratory diseases, air cleaners are necessary.
Type of Air Purifiers
The most common sort of air purifier maintenance is the replacement of air filters.
- HEPA Filters: Based on usage, HEPA filters last roughly a year.
- Carbon Filters: Activated carbon filters have a six-month lifespan.
High-Efficiency Particulate Arrestor – HEPA
HEPA (High-Efficiency Particulate Arrestor) is an excellent mechanical filter that helps in removing 99.97 percent of PM 2.5 pollutants. HEPA air purifiers catch carcinogen particles such as dust mites, pollens, pet dander, mold spores, and tobacco smoke via three different mechanisms: impact, interception, and diffusion.
HEPA air purifiers use a four-step technique to effectively remove 99.97 percent of particles from the air.
Carbon Filters
Carbon filters clean the air by passing it through an activated charcoal screening, making them ideal for removing smoke, odors, pollutants, and any other impurities. Activated carbon catches passing pollutant molecules before eliminating them from the air because it is incredibly porous.
Also Including some filters are Ionic Filters, Carbon Filters, Ozone Filters.
Ionic Filters – Ideal for removing small pollutants from large spaces, Ionic filters use a small but intense electrical field.
Ozone filters target lingering odors but do not clear any allergens or chemical pollutants that may be present in the air.
Carbon filters pass air through an activated charcoal screen, making them ideal for clearing smoke, odors, chemicals, and any gases from the air.
Room Size
Another crucial element to consider when buying an air purifier is the size of the room. Air purifiers that are larger in size are required in larger homes, and conversely. There are a variety of air purifiers available on the market, varying in size from little to large. As a result, double-check the coverage area parameter and compare it to the size of the room you want to cleanse.
When you’re looking to buy an air purifier you’ll most probably come across two parameters in the specifications list:
- ACH
- CADR
The acronym ACH stands for Air Changes Per Hour. The ACH figure indicates how many times per hour the purifier can replace the air in a space with clean, fresh air. In one hour, the purifier completes a certain number of purifying cycles. It is often expressed in ‘x’ multiples, such as 3x, 4x, 6x, and so on.
The maximum square foot area that an air purifier can manage is determined by the ACH rating. If your purifier has a 5x rating and is rated to cover 200 square feet, it will not maintain the 5x exchange rate if you set it in a space that is larger than 200 square feet. Its efficiency would suffer, and the air would be less clean.
CADR stands for Clean Air Delivery Rate. this rating helps the consumers know how well the air purifying device can clean the air within a specified room. Interestingly, not all air cleaning devices include a CADR rating on their list of specifications. The main benefit of CADR rating is that it allows you gauge how large room can the air purifier handle smoothly.

To assist users in keeping track of the air quality they are breathing,
Air Purifier Placement
Instead of utilizing a fan, air purifiers that use ionic/UV filtration technology produce ions and radiation in a 360-degree circle. As a result, positioning the appliance next to the wall will reduce its total output. The optimal location for such purifiers is in the room’s middle.
