How to Change Your Air Filter

One of the most important things you can do to maintain the efficiency of your HVAC system is to change your air filter regularly. A clean air filter helps trap airborne particles and contaminants before they can enter your lungs. It also helps keep your HVAC system clean and free from dust and dirt.

Most experts recommend changing your air filter every three months, but if you live in a particularly dusty or pollen-filled environment, you may need to change it more often. In addition, some air filters are designed to be washed and reused, while others must be replaced each time they become clogged.

In addition to inhaling airborne contaminants, a dirty air filter can overwork your HVAC system, which leads to higher energy bills. Here's a step-by-step guide to help you get the job done:

Adjust the Thermostat

Locate all your filters

Depending on the HVAC system that is installed, your home may use one or more filters.  These filters may be located in the (a) air return registers in different rooms around the house - look for the large metal grate on your wall, ceiling or closet door or (b) central air handler system with a dedicated compartment for the air filter.  Some homes may have wall mounted AC heads in each room and the filters may be part of this unit.
After you have located the filters, measure the sizes of the filters.  Using the correct size is important for the filter and the HVAC system to work efficiently.   

Remove the Grille Cover

The next step is to locate and remove the grille cover. 

At the return air register, just unhook the latches. For registers on the ceiling it is often convenient to keep the vent fan on.  This will ensure that the filter does not fall on you as you open the grill cover.  

At the air handler, see the unit's instructions.  In many cases, you may have to turn off the HVAC system.  Loosen any screws or nuts holding the grille cover to remove it. After removing the lid, you should be able to see the air filter.

Remove the Old Filter

After locating the grille cover and removing it, you can remove the used air filter. Quite often, if the filter fits snugly into the housing and may be difficult to remove.  Luckily, an Airzey air filter purchase includes a handy tool that helps you remove your old filter easily without damaging your nails.

Clean the Grille Slats

While you're changing your air filter, take the opportunity to clean the grille slats.

If your grille slats are dirty, they can restrict air flow, impeding the proper functioning of your thermostat. The grille slats allow air to flow freely into the unit. If they are blocked by dirt or debris, it can introduce dirt into your ductwork cause the HVAC system  malfunction.

By cleaning the grille slats when you change your air filter, you can not only keep your home clean but keep your ductwork clean and your HVAC system operating optimallly. 

Insert the New Filter

To install your new air filter, simply insert it into the housing. Ensure that the direction of the airflow arrows on the filter is correct.

Once the filter is inserted, close the cover and screw it back into place. After changing your air filter, dispose of the old filter properly. It is a best practice to seal  it in a bag before throwing it away because it may still contain harmful particles.

Set a Reminder for the Next Replacement Date

Always set a reminder date for the next replacement of your air filter. Otherwise, it will be easy to forget, and dust and other particles might accumulate on the filter, making it less effective.

A dirty air filter forces your HVAC  to work harder than it needs to, causing premature wear and tear. Regularly replacing your air filter will help your HVAC last longer.
