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.

If it's PLA or PETG it's probably still usable. PLA can get brittle if it's wet though but drying should make it usable again.

I use a cheap food dehydrator to dry filament.
