I rarely write reviews, but this was rediculous. The box on my door step looks like it was kicked there by Ace Ventura. I open it, and the filters are in there loose. No labels, no other box or branding, just the blue filters. They were shrink wrapped, but that isn't very reassuraning. I can shrink wrap my toilet and send it to you, doesn't mean it's safe to drink out of. Did I mention nothing in the box with these? Not even instructions. Do I soak for 15 minutes or just rinse them like the last PUR filters I bought? Your wondering if I returned these sketchy filters.... No, I am using them because I can't find PUR filters at any stores or online. I just know that I will not be buying these in the future.
