Hello...new member here! Great source of info!
Anyway I acquired 3 unused boxs of 3 different filters but they are very old...i'd say early '80s manufacture. One of the sizes will fit one of my applications but should I use them because they are so old? The specific filters are:
1) STP S-02849 (dated 1981)
2) Warner PH-2850 (probably 1983-1984)
3) P&D (Facet) OF-2850 (these look quite nice)
If not wise to use, are they just trash???
