CFS2 Pack Heavy Duty Water Filter Cartridges Compatible with RS6-R-05, BF7, BF9C, BF35 Models – Remove Bad Taste & Odor – Whole House Replacement Filter Cartridge – White

Very good quality

After changing the first filter out after 3 months of service, not only did I find the same amount of discoloration on the inside of the filter as the outside, there was also an awful glue like substance collected on the bottom of the filter, something I’ve never seen in any of the other filters I have used over the years. Threw the other filter that came in the 2 pack right in the trash.

Good filters. They don’t fall apart.

The discription says these are RS6 filters but they are smaller diameter and diffeerent length than the RS6 filters I currently have. I am returning them.
