The air coming from the air conditioner must have to pass through the air conditioner filter to ensure healthy indoor air quality. Dust, mold, fungus, and all other pollutants get filtered through the air conditioner. And in order to keep your indoor air free from such dangerous pollutants, you should be heedful about the optimal working of the air conditioner filters. There are several types of air conditioner filters and they have their particular strengths and weaknesses. So, that is why you should choose the one that works best for your home and your own health goals.

Let’s see which major types of air conditioner filters are being used commonly and what are their effects on indoor air quality.

  • HEPA Filters
  • Media Filters
  • UV Light Filters
  • Electrostatic Filters
  • Pleated Filters
  • Washable Filters
  • Spun Glass Filters

HEPA Filters

If you want to remove at least 99.97% of airborne allergens and pollutants, then high-efficiency particulate air filters are the ones to choose. Even if the dust particle is as small as 0.3 microns, your HEPA filter will be able to remove it easily. HEPA filters are also recommended by the U.S Department of Health.

So, if you have some sensitive health conditions like serious allergies or respiratory problems, opting for HEPA filters can be a good choice.

Media Filters

Even though having equal high MERV ratings, media filters are much more beneficial than standard filters because they do not come with cons. They come without the fuss of airflow or static pressure. Even though the benefits of having media filters are a lot, for example, they are low-maintenance, cost-effective, and trap the pollutants greatly, but they are not very effective when it comes to dealing with odors.

UV Light Filters

With the germicidal radiation, the UV lamps inside the filter use short-wave UV light to kill germs, viruses, and bacteria. It can eradicate mold spurs very efficiently. However, it is observed that even though UV light filters are very efficient in removing germs and viruses, they are not equally effective when it comes to trapping dust.

A big con of UV light air conditioner filters is that they can turn oxygen into ozone which is extremely bad for your health. Conditions like cough, chest pain, or even asthma can be triggered in such a situation.

Electrostatic Filters

If you are very wary about the allergens being trapped, you should surely opt for electrostatic filters. Rest be assured that dust and all airborne particles will be trapped quite efficiently. However, it has been reported that electrostatic filters lack in handling bigger pollutants. So, if you have serious respiratory issues, this choice can not be very good for you.

Using electrostatic filters is a very cost-effective choice as they are reusable, so you do not have to ever worry about buying their replacement.

Pleated Filters

Having a bigger surface area, pleated air conditioner filters are able to handle bigger pollutants and debris. They are a very durable choice and they also can be recycled easily. Another amazing benefit of a pleated filter is that they also help suppress the noise of the HVAC system.

Being such heavy-duty filters, they improve the indoor air quality to a great extent. The only major con of having pleated filters is their cost as they are an expensive choice. But they provide value for money.

Washable Filters

An environmentally friendly option for you is washable filters. Washable filters are reusable and a very cost-effective choice. Even though the initial price is high, but it proves to be a cheap choice over the years because of its durability. If you are not very conscious or have some certain health condition, the washable filters can be your best bet! However, the washable filters require a great deal of care for use. They come with a special set of instructions if you want them to work optimally.

Spun Glass Filters

This is one of the most popular choices among air conditioner filters. They are extremely cost-effective yet very efficient in their entity. They are very effective in catching debris and dust right away. However, they can only trap debris and dust so they are not a great choice for someone who has respiratory issues and is looking for some certain type of air conditioner filter that can improve the indoor air quality.

So, here we have listed above some of the most common and effective air conditioner filters choices from which you can choose. It is important for you to make an informed decision, so we are just giving you a jumpstart through this article. Hope it helps!
