They have not yet received niosh approval, but have completed testing to the n99 standard.

Do these come with replacement one-way valves? Or are they just the inner filter?

This is just the filter. Replacement valves can be purchased separately.

Do large RZ2 filters fit the medium mask or must I buy medium filters?

You should use the medium filters in a medium mask to achieve the best fit. You may notice excess material at the top or bottom of the mask if you use a large filter in the medium mask.
