Something is up lately. Filter is not lasting as it usually does, lasts 20 days max now. Also it doesn't look that dirty. And the center is caved in more. The quality of these filters is not as good as they used to be.
Works well
This filter is dangerous. After just a few weeks this filter suddenly plugs and blocks circulated air. Heat exchanger overheats and glows red. Safety shuts down furnace. This filter was even behind an old school spun prefilter which only blocks the larger dust balls, if any. This 3M filter was bowed out like schooner sail. Keep away from this one.
Everything was a 5 star !
perfect fit. appears to be very high quality.
