Can you use the caps without a filter to not use up the filter as fast when drinking pre-filtered water?

Yes, works just fine as a replacement cap, without the filters on my Nalgene 22 oz bottle.

Could this be used as a gravity filter?

It can’t. It’s literally a straw.

what type of nalgene bottles can this be used with?

All the standard 1L bottles, plastic only, asI did not try any metal versions of Nalgenebrand.
