While some homeowners believe pleated air filters will improve their HVAC system’s performance because the increased surface area traps more debris, the drawbacks tend to outweigh the benefits. Filters keep allergens like dust and pollen out of your home, improving indoor air quality—but according to air conditioner service experts, pleated models don’t work as well as flat ones. Here are three reasons to avoid these products.

They Clog Easily

The pleats in these filters add more surface area; although this makes the filters effective at blocking allergens, it also means they are more likely to get dirty, especially when dust collects between the pleats. This buildup prevents the filter from functioning efficiently, forcing your HVAC system to work harder and increase your energy expenses.

They Have Lower MERV Ratings

Every HVAC filter has a maximum efficiency reporting value, or MERV, rating that tells consumers how well it controls indoor air quality. This scale ranges from 1 to 20; the higher the number, the more effective the filter is at trapping fine particles. Even if the material used to make a pleated filter has a high rating, its bulkiness creates a new problem by lowering the pressure of the air leaving your ducts, meaning neither the filter nor your heating and cooling equipment can operate efficiently.

They Reduce Airflow

Today’s pleated filters are thinner than previous models and have higher MERV ratings. Unfortunately, that only means they’re reducing airflow even further instead of eliminating small debris. How do you resolve this problem? Look for the same MERV rating on a thick, flat filter rather than a pleated one. Thicker filters consist of layers of fine mesh that offer more room for air to pass, catching particles the way they’re supposed to and leaving your house noticeably fresher. 

Making the switch from pleated air filters to flat ones maximizes your HVAC equipment’s performance.
