Do 3 Month Air Filters Really Work? - A Comprehensive Guide

In general, most air filters manufacturers and HVAC companies recommend changing the filter every 90 days or 3 months. This can vary depending on the location of your home, if you have pets, and the age of your system and equipment. Some air filters are designed to last up to six months, while others must be changed monthly. The density of the air filter is a key factor in how long it will last.

You can determine this by looking at the thickness of the filter rather than the brand. Additionally, you should check the MERV classification. Fibreglass air filters are more affordable but less efficient at capturing dust and particles from the air. These usually need to be changed every 30 days or less.

After a period of smoky days with poor outdoor air quality, inspect the air filter to see if it needs to be changed. When you change the air filter, you allow more air to flow through the system with lower energy consumption. This translates to better circulation, cleaner air, and a lower electricity bill. The ideal is to change your air filter every three months; however, there are certain factors to consider when determining when to replace an old filter. High-quality pleated air filters create less air resistance, which can help the HVAC system operate more effectively and reduce wear and tear on components, including the fan motor. If you have young children at home, it's a good idea to use these filters and change them every two months.

Cats and dogs usually lose more hair when winter turns to spring and summer to fall, which are key times to change the filter. By eliminating air contaminants (both chemical and environmental), your family will be able to breathe cleaner air every day, and your electricity bills will also be reduced because your HVAC unit won't have to work as hard. Consider all factors when determining a replacement program and decide what type and quality of filter you should use. If any member of your family has mild to moderate allergies, you can add a better air filter or change it even more often. For every dog that sheds hair, be prepared to replace the filter a month earlier than you would in a pet-free home. While these factors influence how often your air filter is replaced, you should visually inspect it every month to check for excessive particle accumulation. A general rule for pleated air filters (such as those made by FilterBuy) is to replace the filter every 90 days.
