apply a filter to multiple layers?

Is there a way to select multiple layers so a filter is applied to several layers instead of just one?

I'm not ready to flatten the image but would like to apply filters to several layers.

Thanks for any help with this.

Read up on adjustment layers.

Or do a copy merged (select all; cntrl+shift+c) which will copy all visible layers to one new one. Then run your filter.

Or...

Run your filter on one layer.

Then select your next layer and do a Command + Option + F (CTRL + ALT + F) [Edited...forgot where I was].

Continue for all layers you want to affect.
