The Different Types Of Air Filters And How To Find The Right One

There are many different air filters on the market, and it can be difficult to determine which one is right for your home. These filters include mechanical, activated carbon, electronic air cleaners, and ultraviolet germicidal irradiation. Besides this, these filters vary in size, shape, and quality to fit different HVAC systems. Each type of filter has its benefits and drawbacks, so it is important to understand the types before purchasing. In this blog post, we will discuss how to find the right filter for your needs. Here are some factors to consider.

Original vs. Aftermarket Air Filters

Original air filters come from the manufacturer of your HVAC equipment. In most cases, they come packed with the device or find them in reputable stores. These air filter brands are designed to fit specific models and sizes, so they may not be compatible with other systems. They also tend to be more expensive than aftermarket equivalents because they have been tested for performance in various environments.

On the other hand, aftermarket air filters are made by third-party companies specializing in producing replacement HVAC parts. These filters will usually fit a wide range of systems, but they may not be as efficient or effective as the manufacturers. Aftermarket air filter brands can also produce models with lower efficiency rates than their original counterparts. It is important to do your research before making a purchase.

Filter Efficiency

Air filters are rated by the minimum efficiency reporting value (MERV). The MERV rating system is based on a scale of one to sixteen. It measures how well an air filter can remove particles from 0.01 microns in size or larger, with higher numbers indicating better performance. A MERV 16 air filter will capture more than 99% of airborne particles, including bacteria and viruses.

It is important to note that some manufacturers may not use the MERV system when rating their products. Some companies use a different scale, such as the Minimum Efficiency Reporting Value (Merv) or Minimum Efficiency Rating Value (MERV). These terms can be confusing for customers who are unfamiliar with them. Make sure to do your research before making a purchase.

Filter Size

Air filters come in various sizes to fit different types of HVAC systems. The size of the filter is important because it affects how well the filter can capture particles from the air. A larger filter will have more surface area than a smaller one, capturing more particles.

A larger filter also creates less resistance, which means that the system will run more efficiently and use less energy. Most HVAC systems require a specific size of air filters, so be sure to measure your current one before purchasing replacements online or at a hardware store. Besides this, you have to ensure that the filter fits properly so that air can circulate through it.

Filter Type

Air filters are made of different materials, including fiberglass and polyester fibers. Each type has its benefits and drawbacks, but one is not necessarily better than another. For example, polyester filters tend to last longer than fiberglass ones because they do not break down as quickly. However, they are also less effective at capturing particles from the air than fiberglass filters because their structure allows some of them to pass through the filter without being trapped inside it.

If you have allergies or asthma, it is recommended that you use a high-efficiency particulate (HEPA) filter to remove more particles from your air. These filters are more expensive than other types, but they offer the best protection against allergens and asthma triggers.


While you may need the best air filter to keep your home clean, you also want an affordable one. The price of an air filter can vary depending on the type of material it is made with and its efficiency rating.

Filters that are smaller in size or have lower MERV ratings will usually cost less than larger ones with higher numbers because they require less energy to produce. However, it is important to note that a cheaper filter might not be as effective at removing particles from your air. So, have a considerable budget and do not compromise the quality of the air you breathe for the price.

Home Air Quality


Different homes have different needs, so it is important to find the right air filter for your home. For example, if you live in a dusty environment, you might need a filter with a higher MERV rating to capture more particles.

If you have pets, you might want to get an air filter that can remove pet dander from the air. And if you are allergic to dust mites, look for an air filter specifically designed to remove them from your environment. You do not want to compromise with the quality of the air you breathe.

Air filters help improve your home’s indoor air quality by removing particles from it. They are available in different sizes, materials, and efficiency ratings. Choosing the right filter for your home will depend on several factors, such as where you live and what type of particles are in your air. The best way to ensure that you have chosen the right filter is by doing some research on your own or asking a professional for advice.
