Is this the same fit as the wp-450w?

I cant answer the question, my WP IS the 560 so not sure about the one you mentioned. If the description states it will fit the WP 450 then it should fit

Will it fit the 464W?

The label on the replacement water tank clearly states that it's for the wo-462w/wp-462c. Your model is not mentioned therefore I would have to say NO

Good OEM replacement

Exact replacement for Waterpik WP-462 OEM tank.Canadian price nearly 2X Amazon US price (in CAD) but then we always seem to get ripped off in Canada.
