Yes, but you're better off forgetting the filter, capturing the full
color image and then doing the B&W conversion and filter manipulation in
your editor after the fact. You can't do after the fact filtering for
polarization but application of color filters in the editor is easy.
For a really quick lesson in deep red filtering use a color image and
turn off the green and blue channels leaving only the red. Then turn
the result into gray scale. But there are more sophisticated means of
creating B&W images.
Here's a nice tutorial on making B&W images with PhotoShop

This is Will Crockett's "Smart Shooter University" site. Lots of good
tips, tricks and techniques here but you'll have to sign up to receive
their news letter and give them your email address in order to get
access to the site. Thereafter you log on with your email address. The
newsletter advertises his classes and seminars but also includes links
to tips such as this. Well worth it.
