Maintaining a healthy home environment often involves tasks that are easy to overlook. One such task is regularly changing your HVAC air filter.

DIY enthusiast Nik from Nik and Liv (@nikandliv.diy) emphasizes the importance of this simple yet crucial maintenance step.

In his video, Nik highlights that air filters trap dust, pollen, pet dander, mold spores, and even tiny bacteria.

If you don't change these filters regularly, pollutants can recirculate in your home, potentially worsening allergies, asthma, and other respiratory issues.

He recommends replacing your air filter every two to three months or more frequently if you have pets, allergies, or live in a high-dust area.

He also provides a straightforward guide on how to change your air filter. The process involves turning off your HVAC system, locating the filter slot — usually in the return vent or near the furnace — sliding out the old filter, checking its size, and then replacing it with a clean one while ensuring the airflow arrow matches the system direction.

Regularly changing your HVAC filter offers multiple benefits beyond improving air quality.

It enhances the efficiency of your HVAC system, leading to potential savings on energy bills and reducing the likelihood of costly repairs.

Maintaining clean air filters also contributes to a healthier living environment by reducing airborne pollutants.
