Nah. Three P1's now $10 at AAP with BIG5 rated 99.9% efficient @ 20um. No contest. Stock up on the best bang for the buck, don't settle.
And some NPS's now use "ARCO's" rubber grommet thingy combo valve . Efficiency unknown. Pass.
Surprised though the Classic has less pleats/media area than P1 in the same application. Same number of pleats and media area in PL and L14610, PL and L14459.
