Frequently Asked Questions

Do Air Filters Have to Be Exact Size?

Yes, air filters need to fit precisely in their designated slots to ensure proper airflow and filtration efficiency. An incorrect size can lead to air leaks and reduced performance.

How Often Should I Replace My Air Filter?

Typically, air filters should be replaced every 1 to 3 months, depending on usage, type of filter, and environmental conditions. Regular checks can help determine the best schedule.

Are 2 Inch Air Filters Better?

Two-inch air filters generally offer better airflow and filtration efficiency than one-inch filters, as they have more surface area and can trap more particles.

Can You Double up Air Filters?

Doubling up air filters is not recommended, as it can restrict airflow, put extra strain on the HVAC system, and potentially lead to decreased efficiency and performance.

Which Type of Air Filter Will Last the Longest?

High-efficiency particulate air (HEPA) filters tend to last longer than standard filters, especially if they are properly maintained and used in appropriate environments, often lasting up to a year or more.
