Used to replace the ProPure FS10 filter medium. I did reach out to customer service to inquire about fitment, quality, 3rd party testing, and they were able to provide answers within a short period; also asked about a discount, because why not, it was worth a shot.
The filter medium was a perfect fit, almost exactly as the removed unit. I did have an issue installing the filter, it needs to be centered, and i believe from the design it tended to lean or rock to one side or the other when screwing the bottom bowl back on. It maybe took a couple extra minutes but I believe I was able to install it as intended. If this could be looked at in the manufacturing process.
The shipping was very fast, I do believe it was shipped within 1-3 days with two day shipping. I use this filter in leu of the fridge and counter spout, so I typically run them for 16-months, with almost no change in flouride or chemical/ heavy metal detected at the time of changing it.
Thanks for helping out.
