Set of brand new, UK made, elements for the Edwards Vacuum EMF20 oil mist filter. Consists of: 1 - A223-04-199 Mist element c/w o-ring, and 1 - A223-04-077 Odor element These are the exact same UK made parts as supplied by Edwards Vacuum. We sell them as a set of 1 of each, for your convenience. (Why buy a pack of 5 Odor elements when you need 1 or 2?) The Odor elements contain charcoal granules and will lose efficiency if not kept sealed, so we pack each one on a resealable poly bag to keep it clean and dry. If you could buy this set from Edwards Vacuum the 2023 set would cost $222.00. (but they only sell the Odor element as a 5-pack) Buy from us at $118.00 per set and save $104.00. 1000s sold over the last 10 years.
