Been looking for these for a long time by CP Watkins (Fairfax VA US)

These were replacements for an air-cleaner system. The old ones were held together with duct tape. These are the exact parts needed. Great website with the parts numbers.

I, unintentionaly (but carelessly) broke the original filter. The replacement is of lighter substance, weight. It will, I am sure, work fine.

PREFILTER by HAROLD N RICHARDSON (PERRIS CA US)

FIT WELL WHEN HAD MEASUREMENTS OF OLD FILTER; EXPENSIVE

Prefilter by Bob Coffey (Loveland CO US)

The new Honeywell replacement filter, part #203372 Prefilter, is approx. 1/8" shorter than the original part, but the pressure clips on the top end allow the filter to fit firmly in front of the electronic air cleaner.
