Review on 💡 Enhance Your GVS SPR321 Elipse with Replacement Filter for Optimal Performance by Jaleel Pruitt

October 2021 and I just received them for my NEXT filter change. The expiry date on the packaging is 8/2022 and for hot water they have a 5 year shelf life. I've been using the latest filter set for a couple of years, having bought a mask and replacement set that I only installed two years ago. Based on the expiration date of the parts I just installed, they expire in January 2022, so were already 3 years old when I bought them. Assuming I get the same benefit from the filters currently installed as I did from my first set, by the time I install the filters I just bought it will be fall 2023 and they will expire in a year. Point. With a 5 year shelf life I assume they will have at least 3-4 years left if I buy them new.
