Why should I change my air filter every three months?

Improve A/C efficiency and reduce HVAC energy costs by up to 15%: According to the Department of Energy, a dirty, clogged filter can obstruct airflow and cause a decline in the performance of your HVAC unit. 

Improve air quality in your home. Filters keep pollutants like mold spores, pet dander, smoke and pollen from circulating around your home.

What is a MERV rating?

MERV stands for “Minimum Efficiency Reporting Value” or the effectiveness of the air filter. The higher the MERV rating, the more efficient the filter is at keeping out dust particles and other contaminants.

How do I know what size I need?

The correct size filter for your air conditioning and heating system is very important for proper operation. A filter that is undersized (or dirty) can restrict the flow of air through your system and affect the performance and may lead to higher energy cost.  Most filters have the size printed on the frame for your reference.

If your unit doesn’t have a filter currently in the system, you’ll need to measure to get the correct size. A general guide to the minimum filter area in square inches (width x height of the filter) is below based on the system capacity (size in tons). The size of your HVAC unit can be found on your outdoor unit's data plate. If your system has two or more filters, this would also represent the minimum combined area of all filters.

Filter Sizing Guide

 What if the filter in my system lists two sizes?

You may notice two sizes printed on your filter. The “nominal” size is the rounded number used by most manufacturers. The “actual” size is the true measurement of the filter. Use the “nominal” size measurement when ordering.
