Should I Be Changing My Air Conditioner’s Filter Now?

The air filter that comes standard with your HVAC system is there to protect the interior of the unit from dust, dirt, and other debris that may enter it. Without routinely swapping out clogged filters, your cooling system will begin to lose energy efficiency, and its components will start to deteriorate. It can also cause ice to begin forming along the evaporator coil—which despite common belief is not normal.

But how do you know when you should change the air filter? The short answer is “it depends.” Less expensive filters require changing more often than their more expensive counterparts due to how they’re made, for example. Keep reading to learn more.

Panel Filters

These filters are typically made of fiberglass and are the least expensive option on the market. They are designed with simplicity, with flat surfaces that trap particles trying to move through them. They can typically be purchased in packs with each filter costing about a dollar. However, they do become easily congested, meaning they have to be replaced once a month.

Pleated Filters

These are a bit more expensive. They’re made of polyester weaves that are much more effective at trapping contaminants and will last longer than panel filters. While it’s dependent on the contaminants within your home, they only need to be changed every 3 to 6 months.

Permanent Filters

We actually advise against using this type of filter, mostly because the moisture they accrue can lead to mold, mildew, and other unhealthy contaminants. However, should you choose to invest in a permanent filter, it must be cleaned every 1 to 2 months, gently with a garden hose. It’s important that you make sure the filter has dried thoroughly before you place it back into the system.
