- Spun Glass 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.
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.

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.
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.

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.
