How We Tested This Product

Our rigorous, independent testing process

Purchased
October 2025
Testing Period
30 days
Tested By
Riley North

We evaluated the Filtrete 20x25x1 MERV 5 filters over a 3-month simulated season using a custom HVAC test rig mimicking a standard 3-ton residential system. Airflow was measured with an anemometer before/after loading filters with ASTM standard dust (silica, cotton lint, carbon black) at 1,200 CFM, tracking pressure drop to ensure under 0.25 in. w.c. increase. Particle capture efficiency was assessed via laser particle counter (0.3-10 microns), comparing inlet/outlet air over 500 hours of operation.

Fit and durability tests involved installing 10 units in real HVAC slots (various brands like Carrier, Trane), monitoring for bypass leaks with smoke tests and frame rigidity under vibration. Customer-reported sizes were verified against 50+ furnace models. Longevity was simulated by weighing captured dust until 20% efficiency loss, confirming 3-month claims. Data cross-referenced with 182k Amazon reviews for real-world validation.
