Are expensive air filters better?

Everyone has seen the endless aisles of heating and air system air filters, but the variety of materials and broad cost range can be confusing. Are the more expensive, pleated filters better than the basic woven fiberglass? Do they have to be replaced less often? Are filters really designed to improve the air in your house, or to keep your HVAC system running properly?

Here is a simple comparison:

The purpose of filters both in your HVAC system and in your air return vents is to keep debris, pet hair and dust out of your unit. Thinner, loosely woven fiberglass filters do the job and allow for better air flow. They are also cheaper so it’s more cost effective to replace them regularly. These filters come in a wide variety of sizes and can be put in air return vents as well as your HVAC unit. It’s important to replace these every 30 days.

Pleated, thicker air filters can be a good option if you have severe allergies, a smaller home, or multiple units that don’t have to move air around the entire house. These filters really still need to be changed every 30 days to get the full benefit of the additional allergen and dust filtering.  It’s important to know that if you have pets, pleated air filters can get caked with hair and dander quickly, making your system work harder to force air through.

Regardless of the type of filters you use, investing in professional duct work cleaning every 3-5 years is a good idea to extend the life of your HVAC unit.  If you’re changing your filters regularly but are still concerned about the air quality in your home contact Central Carolina Air Conditioning at 800.461.3010!
