Using old filaments (self.3dprinting)

Hello,

I put my homemade 3D printer in the garage when I moved 2 years ago, the filaments I had were maybe 2 years old and worked well.

I bulk bought them on aliexpress or maybe alibaba.

Now, the printer needs a refreshing, a bit of all kind of electrical & mechanical stuff and also figuring out how to run it from my new computer, and I wonder if I should buy some new filament so that I won't have to care about any old filament problems or what do you think? Is my filament dead or maybe ok?

Thanks!

Edit: thank you all!

I'll go with buy a new high quality one to get everything up and running, and then I'll check out the quality of the old spools. Who are stored open, but in a airtight box with a kilo of, now grey, alibaba deciccant pellets.

Stored in vacuum bags with dessicant?
Or stored on a shelf in the open?

Either I'd buy one known good roll to calibrate your printer, then take it from there with he old stuff, see how good/bad it is.

A filament dryer might something to look into.
There's also a case to be made of not buying more filament than you can use to avoid these situations where you're stuck with old sketchy stuff.
