Hello Klean Shower Filter purifies your water through 6 steps: 

Stainless Mesh: Captures sand and other sediments.  

Calcium Sulfite: Ensures chlorine removal in both hot and cold water. 

KDF 55: Helps remove residual chlorine and heavy metals such as lead, chromium, copper, mercury, nickel and copper. 

Granular Activated Carbon: Helps remove trihalomethane (THMs), odor, mould, and bacteria. 

Ceramic Beads: Balances your shower water's pH level.

Our filter uses an NSF (National Sanitary Foundation) certified medium called Kinetic Degradation Fluxion (KDF) which uses a process known as REDOX to transform chemicals and metal ions into harmless substances for your hair and skin. KDF meets EPA and FDA standards and is 100% safe for your shower.

KDF utilizes a combination of copper and zinc to create an electro-chemical reaction. During this process, electrons are transferred between molecules, creating new elements. The process changes harmful contaminants into harmless components. Free chlorine, for instance, is changed into benign, water-soluble chloride. With the same reaction, some heavy metals such as copper, lead, mercury, and others, react to plate out onto the medium's surface as well.

Each filter also contains Calcium Sulfite (CaSO3), which helps effectively remove chlorine from your shower. Calcium sulfite is a vital component within both household and municipal filtering systems and also used in our daily lives. 

There's also Granulated Activated Carbon (GAC) which help remove THMs, odor, organic materials, and bacteria. GAC is microporous, which means just 1 gram of activated carbon has a molecular surface area of 11 tennis courts. GAC attracts the icky things in your shower and ensures that they stay permanently trapped. According to the EPA (US Environmental Protection Agency), GAC is the recommended filter media that removes 81 types of chemicals, 32 identified organic contaminants as well as 14 different types of pesticides and 12 herbicides.

Our filter ingredients are produced in Michigan, USA and the packaging and assembly is completed in Shenzhen, China. 

The filter's flow rate is 8 liters per minute, and it shouldn't change your water pressure noticeably.

Our product is designed for home showers only, so please do not install it onto any pressure piping.

Consider capsule replacement if you notice a significant reduction in water flow. Decreased water flow is not a product deficiency, but a sign of increased sediments in your shower water.

The Hello Klean Shower Filter will help remove limescale to a limited extent, but ultimately, we are a water filter, not a water softener. 

Our filter removes chlorine, chemicals, and water-soluble heavy metals like iron, nickel, copper, chromium, lead, etc. These minerals are found in hard water and can leave your hair and skin feeling dry and weighed down.

If you're looking for a solution to remove limescale and calcium 100%, we suggest looking for a whole house water softening system. 


Nope! Hello Klean is designed to be 100% hassle free, so you definitely won't require a handyman.

Here's how to install it:
1. Unscrew your shower hose (the pipe) from the tap.
2. Remove the rubber plugs and attach the entry valve to the bottom of your shower tap (with the rubber seal facing upward).
3. Attach your shower hose onto the exit valve.
4. Tighten both sides to prevent any leakage.
5. Let your shower water run for 1 minute, and you're good to go!

Changing our capsules is super simple:
1. Remove the filter from your shower hose and tap.
2. Unscrew the inflow and outflow covers.
3. Remove the existing capsule, replace it, and screw on the caps.
4. Re-attach the entry valve to the bottom of your shower tap (rubber seal faces upward).
5. Re-attach your shower hose onto the exit valve.
6. Let your shower water run for one minute, and you're done.

We advise to change the capsules every 3-4 months or after 13,000 liters of water (whichever comes first) for optimal results. Replacement should not exceed 6 months (DIN1988 Section 4).

How long each capsule lasts depends on various factors. The optimal performance varies on the level of free chlorine, pH balance, how hard your water is, how often you shower, etc. 

If our filter doesn't fit in your shower, you can send it back and we will issue a refund immediately.

Alternatively, we can send you an adapter free of charge that can help!
