For many people, diving is a must-do on vacation. Unfortunately, we cannot always assume that every filling station will provide safe breathing air. The personal filter (intermediate filter) provides certainty about safe breathing air. The filter is easy to place on the tap when you are going to fill the bottle, so that the air is filtered even more. Of course you want to keep a clean diving cylinder clean. That is why you use the personal filter when you want to be assured of the safety and quality of the breathing air. Enjoy the (diving) holiday!
