The Omni Filter® OM34K 34,000 grain capacity cabinet water softener is recommended for homes with 2 to 4 people and features exclusive smart reserve technology which anticipates your daily water usage and ensures optimum efficiency. Programming is as simple as 1, 2, 3: set your time, water hardness, salt setting, and you're done! The OM34K is a highly efficient, high-flow water softener that will help protect your plumbing and appliances from hard water damage, help reduce your energy bills, and save water. Soft water also feels different; it's noticeably smooth to the skin. You will use less soap when you clean and even save time because there's no longer any hard water build up on your sinks, bathtubs, or dishes.
