SpectraPure MPDI MAX-KIT RO Membrane & DI Cartridge Upgrade Kit -FK-MPDI-MX
Premium quality products. Delivery was fast and well packed.
I have used these filters for many years and still say they're the best. My only problem is the shipping partner. USPS is the worst. The box arrived practically destroyed, but the filters were still in good shape. This happens all the time with this carrier on top of delays.
Thank you for your review and your continued support, I am sorry about the shipping issue.
