We have a Westinghouse F/F purchased from Noel Leeming. Unfortunately, they don't sell the filters, so had to look online. I quickly found NZ Pump and Water Filters. I made the call and within 5 mins I knew what to purchase online. I made the pick-up 2 days later. No hassle arrangement. The water wasn't pumping through at first, but I think the filter wasn't quite fully turned so it wasn't locked into place. Once locked in and after pumping a few litres through it all good. The water is nice and clear and taste fine. So, all good after 2 weeks of usage. I would recommend this alternative filter. PS I bought a second one as they were on special.
