Last December I ordered 3 water filters for a Big Blue filter.
The number was 155121 PP30-BB
The sizes are 4 1/2″ x 10″ it’s 30 micron – Pleated Polypropylene.
This filter no longer appears on the list of options. Is there a different number that replaces this filter.
Also, I would like to try a smaller micron filter (10 micron?) – what filter would work?
As you stated, the 30 micron PP30-BB is no longer available.
Another low micron big blue filter would be the WP10BB97P. Thats 10 micron only.
