GermGuardian Furnace Air Conditioner Air Filters

A MERV 12 rating indicates a high level of filtration efficiency. These filters are capable of trapping smaller particles like pet dander, mold spores, and fine dust, making them an excellent choice for households with allergy sufferers or pets.

Check the dimensions printed on your current filter or measure the slot in your furnace or air handler. These filters measure exactly 16 x 25 x 1 inches, so ensure your system is designed to accommodate this specific size.

For optimal performance and to maintain good airflow, you should replace these filters every 90 days. If you have pets, live in a dusty area, or run your system constantly, you may want to check them every 60 days to see if they need an earlier change.

Because MERV 12 filters are denser than standard lower-rated filters, they can slightly increase resistance. Ensure your HVAC system is in good working order and that you change the filters regularly to prevent strain on your blower motor.

Yes, these are designed for standard HVAC systems that use the same filter for both heating and cooling functions. As long as the dimensions match your system's requirements, they will work effectively for both.
