The most efficient respirator is an N100 or P100 elastomeric, not N95.
Generally, you should not wear anything over a FFP N95 because it can distort the shape of the mask and allow air to leak in around the mask.
If you are in a setting where you need to protect against splashed liquids as well as from airborne particles, then consider wearing a face shield, or wear a medical N95 that is resistant to body fluid splashes.
If you are trying to protect against current variants of the SARS-CoV-2 virus, you should wear an N100 or P100, especially if you are in an enclosed space with someone who is symptomatic, because an N95 may not filter out enough of the virus particles to prevent infection.

*Most efficient at a reasonable price. PAPR respirators are more efficient but cost thousands of $.
