Now AC filters come in many variants and each one has different advantages. We will talk about each type of air filter and tell you how it works.

  1. Electrostatic filter

Electrostatic Air conditioner filters use electrostatic chargers to remove dust particles. The magnetic effect of the charge attracts debris and other dust particles. They stick to the filter due to the constant charge. They should be washed later.

The great thing about electrostatic air filters is that not only do they reduce harmful particles in the air, they are also easy to clean. Additionally, these air filters also come with a lifetime warranty and are quite effective.

The only thing to keep in mind when getting an air conditioner with these filters is that you need to clean often.

Constant cleaning of the filter will give you many years of excellent performance. Usually you will see that these air filters are used in Daikin AC.

  1. Nano-Silver Filter

Nano-silver filters are some of the best filters out there, due to their antibacterial quality. The technique is mainly based on the treatment of bacteria. Samsung has said that this technology can disinfect up to 650 types of bacteria.

The technique works using a combination of two things, namely, superoxide and hydroxyl ions.

Superoxide ions are made using titanium dioxide, which causes electrons to be excited when exposed to ultraviolet rays.

The final reaction of the products with oxygen subsequently leads to the formation of superoxide ions. Then another reaction occurs, with water vapor, which leads to the production of hydroxyl radicals.

Superoxide and hydroxyl ions are lethal to bacterial cells when they come together, giving way to the spread of clean and safe air.

  1. Pleated Filter

Pleated air filters are powerful filters that provide more powerful filtration than average filters offered by some manufacturers. Air conditioner filters  are made from plates of a single wire synthetic medium and are quite efficient at removing microscopic particles from the air.

They can kill even the smallest bacteria along with other impurities like dust, pollen etc. They are so effective because they have more fiber per square inch. The more fiber in the filter, the better it can handle air particles.

  1. Mechanical Filters

Mechanical Air conditioner filters are the most common air conditioning filters used in AC. These capture particles from the air through the use of synthetic fibers, preventing them from affecting the air. However, these filters have different properties.

Basic mechanical filters do not actually clean the air and do not have high MERV ratings, ranging from 1 to 4.

They are inexpensive and only serve to block dust, for the most part, preventing damage to your equipment. However, they do not clean the air.

It also contains pleated cotton or polyester mechanical filters, which work best to remove larger, more harmful particles.

Therefore, they are better at cleaning the air. However, they need to be cleaned more often than their original counterparts.

The most effective mechanical Air conditioner filters are HEPA (High Efficiency Particulate Air) filters, used in many fine air conditioners. They can remove more than 95% dust, pollen, bacteria, and other particles from the air.

For maximum efficiency, these filters should be cleaned every three months or as soon as possible.

  • The MERV rating we mentioned earlier is important when you are considering an air filter, because it tells you how well the filter can clean the air.
  • A higher MERV (Minimum Efficiency Report Value) rating means that more particles will be removed from the air.
  • However, you do not need to use an air filter with the highest MERV rating, unless you have trouble breathing.
  • For a normal person, filters with a MERV rating of 5-8 should suffice. They can filter the air thoroughly, removing common harmful particles such as dust mites, pollen, lint or other relatively small ones.
  • Just be sure to change these filters frequently. However, one thing to keep in mind is that AC has a specific range as can adjust MERV ratings.
  • Just be sure to change these filters frequently. However, one thing to keep in mind is that AC has a specific range as can adjust MERV ratings.
  • You can find the range somewhere in the manual. Going over the limit can damage the conditioner.


Now that you know how the Air conditioner filters works, you can go ahead and find the best air conditioner for you.

This article should help you find an air conditioner that does not cause problems for your body and provides clean, healthy air.
