LOL, I hear that!!!!Check out the baby Hailea filters they are really cheap but are very reliable. I have used them for years. I used to always have a back up filter just in case one failed but they never did.
I have spare filter and heater tucked away in the drawer that all manuals warranties are stored.
I do the same with the business I have a new spare 4.5” grinder and chop saw in case one breaks I can continue. Old saying is if it ain’t broke don’t fix it!! And it is true in general, that said I’m not above re investing to upgrade as and when needed.
