Filters can last from a few weeks to several years. In part, it depends on the materials they were made from, and their designed life span. As a general rule, most cartridge filters average 1 year. We recommend that you chemically clean your spa filters every 30 days to extend filter life. Not just spray them off with a hose, or rinse them off in the sink. A good Filter Cleaner & Degreaser will help remove oils and scum from the filter media.
How long does a portable oxygen tank last? Oxygen tanks can last between 0.75 and 37.5 hours. How long they last depends on the size of the tank, the pressure in the tank and the flow of oxygen, which ranges from 0.5 to 5 liters per minute. For example, a D-size tank that is full last only 1.25 hours at 4 liters per minute but can last 10 hours at 0.5 liters per minute.
