This filter is good for up to 12 months, meaning it costs about $0.11 per day, making it not just a great product but a really good value for your money as well.

That way, it won’t move when you turn the water on, though you can always make sure to tuck it behind the lever on the nozzle.

When you turn on the water, it will pass through the ball faucet filter, letting softer water fill your tub. Don’t worry about it overflowing, no matter how fast you have the water turned on. There is a flow rate extender funnel that will prevent the ball from overflowing.

After you use the CuZn Bath Ball Faucet Filter, you will immediately notice a difference in your skin and your hair as it is intended to reduce dry, itchy, and flaky skin, brittle hair, and other eye, lung, and sinus irritations.

When you need a new filter, you can purchase a new one so you won’t have to replace the entire casing unlike other similar products on the market.
