Frequently Asked Questions
How often should I replace a 1" furnace filter in a college apartment?
Replace 1" pleated filters every 60–90 days for typical use. Replace more often (every 30–60 days) if you have pets, allergies, or a dusty environment, and keep a multipack on hand so swaps are quick between roommates.
How do I measure the right filter size for my apartment?
Measure the opening (height x width x depth) in inches, or remove the old filter and read the printed dimensions on its frame. Note nominal sizes versus actual size listings: some packs list a nominal size but show actual measurements that may differ slightly—use the actual dimensions when in doubt.
Can I use a higher MERV filter in an older apartment HVAC?
Higher MERV filters trap finer particles but can restrict airflow if your system isn’t designed for them. Before upgrading above MERV 8, check the HVAC manual or ask a technician—many student apartments are best served by MERV 8 1" filters for a balance of filtration and system compatibility.
