Review on Pentair OMNIFilter Sediment Replacement Cartridge by Dana Mahendra

I've used them in the past and they do the job perfectly. They used to be sold at my local hardware store but now they sell another brand imported from a country that doesn't know quality and safety. They are and were made in Mexico. I'm glad I can still get this safe, high quality, North American made product from Revain! Another reviewer asked about the Proposition 65 warning label on their filter. Now it's almost everywhere, even Disneyland! My filter has this warning printed in small print in the corner of the label.
