CFS4 Pack Sediment Depth Water Filter Cartridges Compatible with Purtrex PX05-9 7/8, 93023 Models – Remove Bad Taste and Odor – Whole House Replacement Filter Cartridge – 5 Micron – 10" x 2.5"

The product itself is not string wound and it is 10 inches long. My type of filter system will not take these , it will only hold 9/7/8 in filters. Before you buy , just know these are the full 10 inches long.

I use these to filter the fresh water for my salt water tank when I make new batches of water for changes. They work well. I will continue to use they for a while.

great item

Works and is much cheaper than supply house I was purchasing before. Fit was perfect.

Just what I was looking gor

Perfect
