Frequently Asked Questions
How often should I change filters in a dorm or studio apartment?
Most pleated filters recommend replacement every 60–90 days. If you have pets, allergies, or live in an area with seasonal smoke, change every 30–60 days. Thicker filters often last longer between changes.
What MERV rating should I pick for a small room?
For typical dorm or apartment use, MERV 8–11 balances filtration and airflow. Choose MERV 11 if you want better allergen and smoke capture. Use MERV 13 only if your HVAC or return can handle slightly higher resistance or if fine-particle capture is a priority.
Can a higher-MERV filter damage my HVAC system?
Higher-MERV filters increase resistance slightly. Most modern systems handle MERV 11–13 without issue, but in very old or undersized units, excessive restriction can reduce efficiency. If unsure, check your system manual or pick a mid-range MERV and consider an in-room air purifier for added cleaning.
