Things You Need To Consider When Looking For an Air Filter for Your HVAC


An air filter is one of the most important components of your HVAC system; it helps protect the motor and other internal components from dust, dirt, and debris that may otherwise compromise its functionality over time. Unfortunately, not all air filters are created equal; some will block more contaminants than others, resulting in greater energy efficiency and longevity of your HVAC equipment. Here are a few things you need to consider when looking for ducted heating return air filter.

Type of Filter

Depending on the type of air conditioner you have, and what type of environment it is exposed to, a different kind of filter may be more appropriate. For instance, if the air conditioner is located in a heavily trafficked area where there are many people and animals present, then having a filter that removes larger particles such as pet dander and pollen may be best. If you live in a rural area with few people and animals, then filters with activated charcoal will work well.

If your home is somewhere in-between these two extremes, then an electrostatic or high efficiency particulate air (HEPA) filter might be the way to go.


You want to look for a ducted aircon filter replacement that has a MERV rating of 10 or more. MERV stands for Minimum Efficiency Reporting Value, and it’s the industry standard used by the EPA and other organisations. A high MERV rating is important because it means that the filter will capture more particles in the air and prevent them from entering your home. Higher rated filters also tend to last longer than lower rated filters before they need replacing, so higher priced filters might actually be cheaper in the long run.

Service Life

One of the most important factors in determining the longevity and efficiency of your air filter is its service life. If a product’s service life is five years that means it will be able to handle 1,000 hours of continuous use. The longer a product’s service life is, the less often you will have to replace or clean it, which can save both time and money.

Size of the Filter

Know the size of your ducted heating vent filters. If it is a 20 x 20 x 1, then you are going to need a 20x20x1 size filter. Some units have filters that can fit multiple sizes so make sure to check before purchasing a new one.

Quality of Materials

Quality of materials is something that most people don’t think about. After all, the air filters just sit there and do their job. But the quality of material matters because it will affect how often you have to change the filters. If you buy cheaper filters, they’ll likely deteriorate faster, and you’ll have to replace them more often. Cheaper filters also won’t last as long as high quality ones. So if cost is important to you, then this might not be a factor worth considering.
