The Birm® Backwashing Filter gives maximum performance when you’re looking for an iron solution. It boasts the best of what Kinetico is known for – a non-electric, twin-tank system. With two tanks, one tank will always be in service. This means you will have an unlimited supply of filtered water and your system will last longer because it’s cleaning itself with clean, filtered water. Using Birm® media, this backwashing filter removes iron and manganese from the water supply. This protects plumbing, appliances, fixtures and clothing. It is powered by moving water, rather than electricity. This means, no clocks, timers, or costly computers. Just a simple, reliable system that keeps your water problem-free with no guesswork!
