According to the manufacturers instructions.
We do not know what you mean by "PFD", please do not use abbreviations. But the answer would be when the instructions for the "PFD" say it needs to be replaced.
You should replace the CO2 cylinder on your inflatable PFD (personal flotation device) after each use, especially if it has been activated. Additionally, regularly inspect the cylinder for signs of corrosion, damage, or a low pressure indicator, and replace it if any issues are found. It's also advisable to replace the cylinder according to the manufacturer’s guidelines, typically every 2-3 years, even if it hasn't been used. Always ensure you have a fully charged and functional CO2 cylinder before using the PFD.
For the newer Inflatable PFDs, most manufactures will tell you when you should replace your cylinder, and most have an easily viewable inflator status. For instance - The Mustang Deluxe Automatic Inflatable PFD: Universal fit states: No inflator maintenance is require for 5 years unless the PFD has been inflated. You can easily view the inflator status and replacement date through the safety inspection window. Green indicates ready for use. However, each manufacturer can have different specification, so it's best to check with your manufacturer and for your specific vest type.

After using an inflatable Personal Flotation Device (PFD), it should be thoroughly rinsed with fresh water to remove any salt or debris. Next, ensure that the CO2 cylinder is intact and properly charged, replacing it if necessary. Finally, check for any visible damage or leaks, and store the PFD in a cool, dry place to maintain its functionality for future use.

An inflatable personal flotation device (PFD) can be used in situations where added buoyancy is needed, such as boating, kayaking, or fishing. They are typically suitable for calm waters and for individuals who are comfortable in the water, as they require proper inflation to be effective. It's important to ensure that the inflatable PFD is Coast Guard-approved and to follow the manufacturer's guidelines on usage and maintenance. Always check local regulations regarding PFD requirements for specific activities.
