Hi, im looking at buying gear from a popular source that comes in a satchet form @5ml/satchet. Im guessing you guys probably know what satchets im talking about.

I've heard a lot of positive input about these but im getting mixed information on whether or not this gear is very sterile or in need of filtering. The popular/trusted site that im looking at claims that the oils are sterile and good to go but i still see people insisting that they need to be filtered.

whats your take on this? Feel free to add anything about your experience or information on satchets.
