What are Pleated Air Filters Made Of?

Pleated air filters are a type of air filter made of a flexible material such as polyester, cotton, or paper. These materials are folded into an accordion-like shape and housed in a cardboard frame. This folding increases the surface area of the filter, allowing it to capture more particles. Pleated filters are highly efficient and promote better airflow, so look for one with many folds for the best results.

A pleated polyester filter with a MERV value of 6 to 8 is an ideal solution. Pleated air filters provide an affordable and low-cost protective layer for your home ventilation system. They trap and absorb more particles than spun fibreglass, such as dust, dirt, and pet and human hair. This helps to protect your HVAC system from damage and improves your home's indoor air quality. Pleatless air filters are not designed to last long, so they are not very durable.

However, you can choose to buy metal-reinforced fiberglass filters for greater rigidity. Most manufacturers recommend buying wrinkle-free air filters because they offer very good filtration and good air flow, which is important for the performance and efficiency of your air conditioner. Electrostatic filters usually have MERV values of 10 or more, so they are very effective in decontaminating the air inside a home. The primary function of an air cleaner is to remove air contaminants from inside your home as they enter the HVAC system.

We have humidifier filters and pads for all major manufacturers (including Air King, American Standard, Aprilaire, GeneralAire and Honeywell). Non-pleated filters are made of fiberglass or some other electrostatic material, which is randomly woven to create a barrier through which air passes. Pleated air filters used to be the cause of many HVAC breakdowns because the system's motor had to work harder than it could handle to extract the air it needed through the hermetically rolled filter. However, when clean air flow can pass through a pleated filter, the result is fresher, cleaner indoor air quality. The oven filter is a protective layer in the furnace air system, but it will eventually need to be replaced. Buying in bulk is a great option; for example, those who buy 3 pleated filters from us (enough to last all year round) save approximately 50% on the cost per unit.

Fibreglass filters are so efficient with particles so small that their percentage is quite close to zero.
