Issues with clogging

Creality Hi Printer
1

I just started to experience some clogging issues with the Creality HI, after hundreds of hours of successful print. I’m interested to hear some solutions from anyone who has experience the same and has solution and prevention methods when it comes to clogging.

Your thoughts . . .

I had the same issue with Ender 3. For 6$ i bought filament filters and never again. I usually use une per spool and when the spool runs out you can see the amount of crap that goes in to the extruder.
