In general, you should change out your air filters every 90 days. However, this isn’t a hard and fast rule. Here are a few tips to help you understand if it’s time to replace your filters, even if it’s been under or over 90 days.
- Know the Thickness of Your Air Filter
Generally, the thicker the air filter, the less frequently it will need to be replaced. For example, a 5 or 6 inch pleated air filter may only need to be replaced once a year, while a one inch pleated air filter may need to be replaced every month.
- Check How Dirty Your Air Filter Is
Even if you don’t think your air filter needs replacing just yet, you should do a visual inspection once a month, especially if there have been any changes to the environment your system is filtering. For example, if the area you live or work in is being affected by poor air quality, you may notice your filter is getting dirtier, quicker. New pets may be another cause of your filter needing more frequent replacements or cleanings.
