What is a Pleated Air Filter and Why is it Better than Standard Throwaway Filters?

small_7398787470Many homeowners in the Glen Carbon and St. Louis Metro East areas use 1” fiberglass throwaway filters with their furnace or air conditioner. These filters are common because they are inexpensive, but they don’t do a very good job at protecting your HVAC system or your health from the contaminants in your home’s air. If you’d like a better filter for your home, but you’re not ready to install an indoor air cleaner, a pleated air filter might be just what you’re looking for.

What is a pleated air filter?

A “pleat” is the accordion-style fold that you can find on certain types of clothing such as the bottom of a dress. A pleated filter is a type of filter that uses this type of folding pattern in order to increase the filter’s surface area without having a big impact on your system’s airflow.

Pleated filters come in a number of different sizes and MERV ratings, and they can be installed in the same slot that throw away filters are housed.

What are the advantages of a pleated air filter?

  • More efficient than throw away filters. Whereas a standard throwaway filter provides a bare-minimum of protection for your HVAC system, pleated filters are much more effective. A MERV 12 pleated filter, for example, can remove more than 90 percent of particles between 3 and 10 microns in size and more than 80 percent of particles between 1 and 3 microns in size. Particles of these sizes do the most damage to your HVAC system, so pleated filters can provide great protection. In addition, pleated filters can remove some of the large allergens in your air like pollen and dust mites, so they can also help improve your family’s allergy symptoms.
  • Last longer than throw away filters. A standard throw away filter typically doesn’t last longer than 30 days. Depending on the type of pleated filter you install, it can last upwards of 60-90 days because of the increased surface area that comes with its pleated design.
  • Little effect on airflow. Another advantage of the design of pleated filters is that it allows for increased surface area without affecting airflow. This is not the case with flat-panel throwaway filters, which can severely decrease your system’s efficiency as they go up in MERV rating.
  • Inexpensive and easy to install. Although indoor air cleaners are much better at improving your home’s air quality and protecting your family’s health, pleated filters are more inexpensive and don’t require a professional installation. This makes a pleated air filter a great choice for homeowners who want to have great protection for their HVAC systems but aren’t yet ready to invest in an indoor air cleaner.

We definitely recommend Tiger!
"My families a/c went out randomly today. I went around the house troubleshooting what I could. It got to the point where we had to call someone. We called the first places that showed up on google. Most places either wanted tons of money just for diagnostics, or couldn’t come out today. We called Tiger they went over the cost and they got someone out to our house in 45 minutes. Josh Moravec was our tech and was super professional, kind and intelligent. He was here for about 15 minutes before he figured out our issue. He went over in depth the cost and verified everything was good before getting started to resolve it. There was no pressure to buy the service if we didn’t want to. He went back down and in 15 minutes the a/c was running strong! He asked if we had any questions and then was on his way! He was great with our kids, very polite and courteous of me and my wife. He answered all our questions, and the price was more than reasonable. We definitely recommend Tiger, and make sure you ask for Josh Moravec if you can!"
