- • Before the cooling and heating seasons begin
Who benefits most
- • Homes with forced-air heating and cooling
- • Pet owners

Before you buy
Honest guidance — you may not need this at all
- • If your system is older or undersized, MERV 8–11 may be the better match than MERV 13.
- • Measure the filter slot before ordering — the printed size on the old filter is the size you need.
Write the install date on the filter frame in marker. It removes all guesswork on the next change.
What it does
- • MERV 13 capture for dust, pollen, and fine particulate
- • Pleated media maintains airflow longer than flat filters
- • Sized for common residential returns
Maintenance tips
- • Write the install date on the filter frame.
- • Change more often during heavy pollen season.
