Signs Your AC Filter Needs Replacement
Watch for these indicators that it may be time to replace your filter:

- No cool air coming out even though the unit is running
- Reduced airflow from vents throughout your home
- Visible dirt or debris on the filter surface
How Often Should You Replace Your AC Filter?
The frequency of replacement depends on the type of filter you have and your particular air quality situation. Factors like pets, allergies, dust levels, and household size all play a role in determining how often your filter needs changing. It’s best to become familiar with your household’s specific indoor air quality needs and replace your AC filter accordingly.
Choosing the Right Type of AC Filter
The type of AC filter you select will affect both replacement frequency and overall system performance.
Fiberglass AC Filters
Fiberglass filters are budget-friendly and easy to find. They provide efficient airflow and cost just a dollar or two per filter. However, they are not as effective at trapping smaller debris and particles like dust mites and pet dander. Fiberglass filters typically need replacement once a month.
Pleated AC Filters
If improving indoor air quality is a priority, pleated AC filters are an excellent choice. These filters are ideal for homes with individuals who suffer from allergies or those with pets. Pleated filters can trap smaller particles without restricting airflow due to their larger surface area. Since they last longer, pleated filters can be replaced every two to three months, making them more cost-effective in the long run.
