How to choose
What MERV means
MERV rates how well a filter captures particles from the air passing through it. A higher MERV number means finer capture. The Simply and JASENG picks carry MERV 8, the Amazon Basics and Aerostar picks carry MERV 11, and the Filtrete pick carries MERV 13. Match the number to what you want captured, and check that your system handles the rating you pick.
Check nominal against actual size
Each pick has a nominal size of 14x14x1, and an actual size that runs slightly smaller. The Simply, Amazon Basics and Aerostar picks measure 13.75x13.75x0.75 inches actual, while the Filtrete pick measures 13.81x13.81x0.78 inches actual. Measure your current filter frame before ordering, and pick the nominal size that matches it.
Change it on schedule
A filter loads with particles over time, so regular changes keep airflow steady. Change the Amazon Basics pick every 60 to 90 days. Change the Aerostar and JASENG picks every 60 to 90 days, or every 30 days during peak summer and winter months. For the Filtrete pick, a change falls at least once every 90 days, and its Smart App sets 30-, 60- or 90-day reminders. Follow the airflow arrow when you insert a new filter.
