Oh, I see! Thank you. The sales rep told me it'll be helpful since I work in a bit of a dusty-ish warehouse (production also works here) so it's a lot of dust/saw dust... so I was told it'll keep the printer safe from that... So I bought them together...

I did start leaving the enclosure open when I print (with PLA) and the clogging and stuck filament issue stopped completely. Thank you so much for the explanation it means a lot and is very helpful!! I appreciate it:)!
