Just ordered this in the last month or two. It was supposed to have a 98% rejection rate. After my own testing, it came out to about 96%. I made Spectrapure send me a new one, so I'm offering this one for free to anyone who wants to come get it. It has about 300-400 gallons through it. I couldn't get higher than 96%, but that's with about 60-65 psi. You may be able to get the stated 98% with a higher PSI. I'd prefer to get it rid of it ASAP before it dries out (ruining it). I currently have it in a sealed bag, wet. Pick up in Ojai.
