Frequently Asked Questions
What is the difference between nominal and actual filter size?
Nominal size is the rounded size commonly printed on the filter frame. Actual size is the precise physical measurement and is usually slightly smaller. Always verify the actual dimensions before ordering.
Which MERV rating should I choose?
MERV 8 is suited to everyday filtration, MERV 11 provides enhanced filtration, and MERV 13 provides higher-efficiency filtration. Check your HVAC system requirements before moving to a higher MERV rating.
How many filters are included?
FeelAir 1-inch air filters in this catalog are sold as a 6-pack.
How often should I replace my filter?
For most homes, every 90 days. Change more often with pets (about every 2 months), allergies (about every 6 weeks), or children (every 2–3 months). Inspect your filter regularly and replace it when it looks loaded with dust.
What if my nominal size matches but the actual dimensions do not?
Do not order based on nominal size alone. Compare your existing filter’s actual measurements with the exact actual-size information shown for the selected FeelAir variant.
