How to choose
Check actual size, not nominal size
Nominal size and actual size differ on every pick here. The Simply lists 16 by 20 by 1 nominal with an actual size of 15.75 by 19.75 by 0.75 inches, while the Filter King lists 12 by 16 by 1 nominal with an actual size of 12 by 16 by 0.75 inches. Measure your current filter and your slot, then compare both numbers with the actual size before ordering.
Read MERV, MPR, and FPR separately
MERV, MPR, and FPR are three different rating scales, so compare like with like. Here the picks rate MERV 8 and MERV 11. The Simply gives MPR 600, the Filtrete gives MPR 700, and the Aerostar compares with MPR 1000 to 1200 and FPR 7. A higher number on one scale does not convert directly to another scale, so check which scale each pick gives.
Plan replacement timing
Pleated filters get replaced on a schedule, and the interval differs by pick. The Simply lasts up to 3 months, the Filter King lasts up to 90 days, and the Filtrete changes at least every 90 days. The Aerostar changes every 60 to 90 days, or every 30 days in peak summer and winter months. Set a reminder for the interval your pick gives: the Filtrete Smart App sets a 30, 60, or 90-day countdown.
