This filter does cost more, but it fits and works. I bought a 4 pack on eBay for $65. Great deal? Nope. The filters look identical and are packaged identically to the real product, except for a sticker placed over the made in America printing. I tried all four and all four wouldn’t seal because they wouldn’t twist on far enough! They also had unwashed carbon and turned the water black. I tried to flush the one that slightly leaked, but even after about 3 gallons the water was still black. I put the old filter back in and everything was fine. I ordered this ‘real’ OEM one from amazon, installed it with no leaking and it’s just as it should be. I did get a refund from the eBay merchant, but they didn’t want their filters back. Dont waste your time with the $16 knockoffs!
