The filament needs to be under 30% RH, and 5% is the best, but it is almost impossible to get there.SunLu has one of the best driers, first; Because it has heat all around, it is well designed and fits most common spool sizes. Tuff for the 2.5 and 5kg user. Unlike me, it has a flaw, LOL. One issue was that they wrapped it up before the designer was done or should have addressed that crucial point.
