I am looking at getting some water filters, 20 inch housings, with 3/4
inch NPT female connections in plastic tops. Can I get away with
screwing in 3/4 BSP taper male brass compression fittings, using a
good wind of PTFE tape??
Both are 14 TPI and the nominal NPT is 1.050 inch OD and BSP is
fractionally smaller at 1.041 inch OD.

No.

NPT is a tapered thread.

BSP is a straight thread.

You cann't get there from here.

We represent some European instrument companies and work with the
importer to supply adapters from BSP to NPT when req'd.

Strictly a convenience item.

Please re read - BSP with a taper male thread - which I can get easily.
