Why Choosing the Right Air Filter is Important

As we spend most of our time indoors, we tend to assume that the air inside our homes is safe to breathe. However, indoor air can contain pollutants, such as dust, pet dander, and chemicals from cleaning products or construction materials. Meanwhile, outdoor air can carry pollen, mold spores, and other pollutants when they come inside our homes either through open doors or windows, or through the air conditioning or heating systems.

As such, choosing the right air filter for your HVAC system is crucial in maintaining the indoor air quality. Air filters help to trap airborne particles, preventing them from circulating in your home, and ultimately, in your lungs. While there are different types of air filters available on the market, the Filter King Air Filters 20x25x1 is one of the best HVAC pleated AC furnace filters to invest in.

The air filter is usually located in the return air duct or air handler of your HVAC system. Look for a large, rectangular vent grille in the ceiling or wall close to your HVAC system. Once you locate it, remove the grille by unscrewing the fasteners or by releasing the latches.

Step 3: Remove the Old Filter

Take out the old filter and dispose of it properly. Check if the filter compartment or grille is dirty and clean it if necessary.

Step 4: Insert the New Filter

Slide the new Filter King Air Filter 20x25x1 into the filter compartment, making sure the airflow arrow on the filter is pointing toward the blower motor. Push the filter in until it fits snugly in the compartment.

Step 5: Reattach the Grille

Reattach the vent grille onto the air return duct or air handler by screwing the fasteners or latching it into place. Make sure the grille is securely fastened to prevent it from falling and injuring someone.

Step 6: Turn On Your HVAC System

Turn your HVAC system back on, and you should feel the air flowing more efficiently throughout your home.
