We have two pfeiffer vacuum MS units, one is their most current model (only 6 months old) the other a few years old, and we go through filaments every couple months. We are hoping an electrical power conditioner would help, what do you think? Thanks for the wisdom

I don't think so. I'd rather analyse the method for solvent deley time.

Or look to see if you have air leaking into the system. Under good vacuum the filament is like a light bulb - and can last nearly forever. But it is the mass of ionizable gas hitting the filament that erodes it.

This I would definitely check. If an air leak is that bad it should have trouble tuning, but it is also a possibility. Make sure you are not having the filaments on when your solvent peak elutes or you will kill your filaments pretty quickly.
