Curator's pick: Food Grade Silicone Grease
Most people overlook this, but if you don't coat the O-rings during the initial install, you'll be wrestling with a seized, leaking housing six months later. It’s the difference between a ten-minute filter swap and a two-hour headache.
⚠ Worth knowing: The 10 x 4.5 inch filters have a much shorter lifespan than the 20-inch 'Big Blue' versions; if you have a family of four, expect to see a drop in water pressure every 3 to 4 months rather than the advertised six.
