Review on 🚰 RF 9999 Faucet Filters by Glacier Fresh by Darrell Shreves

I give 5 stars.*I like these filter blocks because they cost a lot less than OEM PUR blocks and the water flows much faster than with PUR blocks. And that worries me. When water goes through carbon filtration so quickly, does it really get cleaned? I don't feel any difference in the taste of this filtered water compared to polyurethane filters, so that's good. I think only a lab test will tell. If anyone else has input, I'd appreciate it.
