Got tired of paying $50+ every six months on those useless refrigerator filters so I jumped out the frig filter and installed this in the boiler room. The carbon block should last for years as long as I replace the $2.50 sediment filter once in a while. What the heck if I have to replace both it will only cost 10 bucks, sure beats $50+ for filters that clog in a matter of 3 months.
