EQ-300 post-filter replacement cartridge, for use with the Rhino Whole House Water Filter.
The post-filter removes particulates 60 times smaller than the eye can see. This includes insoluble minerals and cysts. The addition of this post-filter is considered a polishing agent and adds a level of protection for your household in the event of an outbreak of cryptosporidium or giardia. This cartridge should be replaced every 9-12 months.
