    Question about filament life

    Hi All, I am a newbie with a recently purchased Ender 3 Pro.
    I added a glass bed and Capricorn tubing after purchase.
    For several weeks it has worked just fine. I use only PLA.
    Some days ago it started to fail early on in printing - just a mess of filament on the plate.
    So I read the forums and did the following:
    Replaced the hot end head (assumed blocked) and associated bowden tube
    Double/triple checked the bed is level.
    Used only default settings for several different prints.
    Attached image is a failure example. Filament everywhere!!
    Now, my question please:
    Could this be due to filament being left exposed?
    I have three reels of filament and they are not stored in a sealed dry container - just the original unsealed plastic bag with the original tiny silica gel sachet.
    Purchased in July so stored for about 8/10 weeks. One reel left on the printer when not in use.
    I have tried using two different filaments with the same results.
    Is there any way to test/check if a filament reel has 'gone off'?
    If it's too brittle, should it snap off by hand.
    I am hoping the problems are due to bad filament. How might I know?
    Any other comments appreciated.
