Prevent this by exploring the types of air filters for home use. Read on as we discuss their pros and cons. Learn more:

1. HEPA Filters

High-efficiency particulate air filters (HEPA) are one of the best types of air filters for HVAC around. They can get rid of almost every airborne pollutant and allergen. It includes dust and mold spores as small as 0.3 microns.

HEPA filters have a MERV rating of 16, giving the highest indoor air quality protection. It gets rid of tobacco particles and bacterial matter. If you have allergies, HEPA filters are your priority.


The biggest advantage of using HEPA filters is the effectiveness of air purification. The filter design is ideal for capturing pollutants like pollen and dander. They’re cost-effective since they can last for a few years.


Despite their purification capabilities, some pollutants go past HEPA filters. For example, HEPA filters are helpless against gasses, odors, and fumes since they’re too small. Some mold spores can settle within the filter, prompting you to replace it soon.

2. UV Filters

These filters use ultraviolet light to purify the air from viruses and bacteria. The UV lamps disinfect the air passing through your HVAC unit. The germicidal radiation makes it an excellent microorganism killer.

UV filters can get dangerous since they can convert oxygen into ozone. It’s dangerous since low amounts will cause chest pain and coughing. If you have asthma, higher ozone levels will worsen it.

If you aim to eliminate microbes, UV filters are the best. However, they aren’t efficient when blocking off dust pollutants. Often, you’ll see these filters as a component of a bigger filtration system.


UV light kills tougher pollutants like bacteria and mold. Your indoor air quality becomes more exceptional since it eliminates the risk of respiratory problems.


UV filters are expensive and can’t get rid of dust, gases, fumes, and smoke.

3. Electrostatic Filters

This filter uses small cotton and paper fibers to make static. It acts like a magnet for airborne particles like dust. It’s strong enough to prevent them from spreading indoors.

Electrostatic filters are disposable and reusable due to their availability. It’s your choice whether to wash and reuse or toss and buy new ones.


Regardless of your choice, these filters are cost-effective. Reusing the filters means never buying replacements and saving money.


Electrostatic filters struggle to handle large pollutants like mold spores and dust. It’s a poor choice if you aim to prevent respiratory problems.

4. Washable Filters

Washable filters are eco-friendly and cost-effective. Its initial price is discouraging, but it’s an investment that will serve you for years to come. It’s the only cost since you can wash and reuse the filter instead of replacing them.

These filters need maintenance to ensure their intended function. Follow the maintenance instructions and you’re good. Ensure that it’s dry before placing it back in your HVAC system.

Otherwise, the remaining moisture can cause mold and mildew to develop.

The MERV rating for washable filters is low. However, if you have no strong preferences for different types of air filters for homes, they’re an investment.


You need only buy washable filters once. It’s durable enough to last the average lifespan of your HVAC system. It’s what makes them cost-effective in the long run.


These filters need regular maintenance to continue working. Remove and wash the filter before drying and reinserting. If you don’t it becomes less effective and can grow mold and mildew.

5. Media Filters

Media filters have high MERV ratings. It gives the same filtration as a high-MERV filter without impacting airflow and static pressure. It’s because of their bigger surface area.

They’re easier to maintain than standard filters. They can filter both bacteria and other small pollutants in the air. They seal these within the filter, preventing them from going back into your indoor air.


They’re low-maintenance and require replacements once or twice each year. Their bigger surface area makes them great at filtration.


They need professional installation. At the same time, they’re not ideal for purifying bad odors.

6. Spun Glass Filters

Manufacturers spin fiberglass strands to make this filter type. It’s one of the most common HVAC filter types around. It’s disposable, cost-effective, and protects AC units and furnaces from various debris.

Spun glass filters are effective but they can’t improve air quality a lot. They can’t strain well, trapping some dust and allergens but not all. It’s why they’re not good for people suffering from breathing problems.


Their price is their primary selling point. They’re cheap and excellent for filtering late debris like dust and lint.


Spun glass filters have a smaller surface area. It makes them useless against smaller pollutants. They can also get clogged, impacting your airflow.

7. Pleated Filters

Pleated filters use either polyester fabrics or cotton folds. Their MERV rating varies, ranging from 5 to 13. They’re effective in removing airborne pollutants but their air filtration levels are low.

The pleats increase the filter’s surface area, making them filter the air better. The more pleats they have, the more effective they become. They can trap even the most difficult pollutants like dander.

You can either opt for reusable or disposable pleated filters.


They’re one of the best choices for trapping debris. Their large surface area makes them perfect for catching more debris types.


Their upfront costs are expensive. However, their long-term benefits make it worth your while.
