in my opinion, one of the best add-ons, especially for the CINQRO and my face type (round and fat as a potato), it does a hell of a job, with keeping away the Filter from my Skin, so the Filter doesn't get that wet, when wearing the Mask for a longer time. In double the Seal Pro gives a much, much better sealing around the edge compared to the Filter itself fixed to the Skin (Especially right under the Eyes) RESPRO'NSE: Thank you for taking the time to write your review. We are very happy to hear the Pro-seal® is working well for you.
