In addition to plastic wrap, several tyvek envelopes of silica gell should be gently inserted (don't forget to remove them later!) to absorb moisture after lightly misting the filters' interior with GC 0W-30, and the carton should also be wrapped in heat sealed plastic wrap after similarly being misted lightly with GC 0W-30.
