How to choose
MERV and pack size
MERV describes how well a filter captures particles, and a higher number means finer capture in this list. The Filtrete and the Nordic Pure sit at MERV 12, the AIRx at MERV 11, the Glasfloss at MERV 10, and the Filter King at MERV 8. Pack size decides how many replacements one purchase covers: the Filter King holds 12 filters, the AIRx holds 6, the Nordic Pure holds 3, and the Filtrete and the Glasfloss hold 2 each. Match the MERV number and the pack count to your change interval.
Nominal size versus actual size
Nominal size is the rounded size on the box, while actual size is the measured size of the filter itself. The AIRx, the Filter King, the Nordic Pure and the Glasfloss share the 16x24x2 nominal size. The Filtrete is a 16x25x1 filter with an actual size of 15.62 x 24.62 x 0.78 inches, so it belongs to a different nominal size. Measure your filter and compare the actual size before buying.
Change interval and reminders
A filter change interval is how long one filter stays in place before replacement. The AIRx runs 60-90 days, the Filter King runs up to 90 days, and the Filtrete runs at least once every 90 days. The Filtrete Smart App sets 30-, 60- or 90-day reminders for its changes. Set a reminder that matches the interval for the filter you buy.
