Frequently Asked Questions
How often should renters replace these MERV 8 filters?
For most small apartments and dorms replace MERV 8 pleated filters every 60–90 days. If you have pets, heavy dust, or seasonal pollen spikes, check monthly and replace more often as needed.
Will MERV 8 filters damage my apartment HVAC system?
No — MERV 8 is designed to balance particle capture and airflow. It provides meaningful filtration without overloading most residential fans. Avoid using much higher MERV ratings unless your system supports them or an HVAC tech recommends it.
How do I know the filter is installed in the right direction?
Look for the airflow arrow printed on the filter frame and match it to the direction of air flow in your return (usually toward the furnace or AC unit). Sliding the filter in with the arrow pointing toward the equipment ensures correct operation.
