What’s the difference between Shower Head, Rain Shower and the Shower Filter?

We make four shower products. They all filter your water as you shower — the right one for you comes down to how you want to install it and the look you're after.Shower Filter (inline)What it is: A compact filter that sits between your existing wall arm and your current shower head or hose.Install: Screws on in a couple of minutes with no tools — you keep your existing shower head.Best for: Anyone who wants filtered water but loves (or is renting and can't change) their current shower head.Rain ShowerWhat it is: A wide, fixed overhead rainfall shower head with filtration built in.Install: Replaces your existing fixed shower head.Best for: People who want a generous, rainfall-style flow and filtration in one fitting.Shower Head 2.0What it is: Our standard handheld filtered shower head.Install: Replaces your existing handheld head and screws onto the hose — no tools needed.Best for: Anyone who wants a straightforward handheld filtered shower head.Shower Head+What it is: Our intelligent handheld filtered shower head. It filters exactly like the 2.0 but adds smart tracking: it monitors your water use and filter life, shows it in the app, alerts you when the filter needs replacing, and tracks your water temperature to warn you when the water is hot enough to stress your skin.Install: Same as the 2.0 — replaces your handheld head, no tools needed.Best for: People who want filtered water plus data on their usage, filter life and shower temperature.A quick note on refills: the Shower Filter and Rain Shower share the same Refill Capsule, while Shower Head 2.0 and Shower Head+ share the same refill cartridge. So if you're choosing between products, you're also choosing which refill you'll reorder.Not sure which suits your bathroom? Message us and we'll help you pick.

What’s the difference between the Shower Head 2.0 and the Shower Head+?

Both filter your water in exactly the same way and use the same refill cartridge, so the water you shower in is identical.Shower Head 2.0 — our standard handheld filtered shower head. Straightforward, no app, no electronics.Shower Head+ — our intelligent version. On top of the same filtration, it:Monitors your water usage and tracks how much filter life you have leftShows all of this in the appAlerts you when the filter is spent and needs replacing, so you're never guessingTracks your water temperature and warns you when the water is hot enough to stress your skin (very hot water can dry out and irritate skin)Because they share the same refill cartridge, switching between them later doesn't change which refill you reorder.In short: choose the 2.0 if you just want clean, filtered water in a simple handheld head; choose the Shower Head+ if you also want to track your usage and filter life and get a heads-up on water temperature.

What’s actually inside the filter, and how does it work?

Every Hello Klean filter is made up of multiple filtration layers, each designed to target a different aspect of harsh water. Coconut-shell activated carbon – Reduces free chlorine, along with the taste and odour that come with it. Activated carbon is one of the most established and widely used filtration materials (ref. 1; ref. 2). Calcium sulphite – Reacts with free chlorine and neutralises it into harmless chloride using the same process relied on in mains-water dechlorination (ref. 3). KDF copper-zinc media – An established redox technology that helps reduce free chlorine and certain dissolved heavy metals, including lead and mercury. Unlike carbon alone, KDF continues to perform effectively in hot water and at higher flow rates. Antiscaling media – Helps reduce limescale build-up, keeping both your shower and fittings cleaner for longer. Every filter is independently RoHS-tested and verified free from restricted heavy metals, so it reduces what's in your water without adding any metals of its own. Like any carbon filter, performance naturally decreases over time and can begin to harbour bacteria if left for too long (ref. 4). That's why we recommend replacing your filter every 3 months.

Shower Filter

Q: Will it soften my water?

Not in the same way as a traditional water softener.A water softener removes the calcium and magnesium that make water hard, usually for your entire home. Our filter doesn't remove those minerals, so your water's hardness level stays the same.Instead, Hello Klean is engineered to reduce the effects of harsh water on your hair and skin.Our multi-stage filter significantly reduces free chlorine, while CRS is used for scale control to help reduce the mineral deposits left behind on your hair and skin.CRS (used in our Shower Heads) is a plant-derived, amino acid-based scale inhibitor that binds to calcium and magnesium, keeping them dispersed in the water rather than allowing them to crystallise and form limescale. It delivers a minimum of 82% scale inhibition across 8,000 litres, helping reduce the buildup that can leave hair feeling rough, skin feeling dry and shower surfaces coated in scale.So while your water isn't technically softer, the result is water that feels noticeably gentler on your hair and skin.If your goal is preventing limescale throughout your home, you'll need a traditional water softener. If you're looking to improve the quality of the water you shower in — and reduce the effects of harsh water on your hair and skin — Hello Klean is a simple, renter-friendly solution.

Hello Klean Consumer Perception Trial 2024

From the first wash, I noticed my hair was a little softer than usual and easier to tame with my comb. I was impressed. Over the next few weeks I noticed this pattern continued and quickly became a convert to the shower filter life.

The filter itself simply screws straight onto your shower hose, the sleek cylindrical body won't ruin the look of your carefully curated bathroom, and it works brilliantly well at sieving out all those damaging deposits.

Since installing, my skin feels so much softer, and my hair is shinier and easier to brush. I'm the first to admit my aversion to all things DIY, but this nifty filter was so easy to screw on.

The built-in filters remove chlorine, impurities and heavy metals using an advanced system that calls on amino acids, activated carbon fibre and KDF 55 (used specifically for removing water-soluble metals).

A multi-stage filtration system is recommended, like this in-line filter that uses KDF 55, calcium sulphite, activated carbon and ceramic beads to filter out chlorine, iron, copper, lead, cadmium and nickel.

Prior to using a shower filter, my hair never felt truly clean — even when I washed it every day. I also spotted a difference in my hair colour. It looks fresher, and the brassy orange hues have disappeared.

FAQ

We make four shower products. They all filter your water as you shower — the right one for you comes down to how you want to install it and the look you're after.

Shower Filter (inline)

What it is: A compact filter that sits between your existing wall arm and your current shower head or hose.
Install: Screws on in a couple of minutes with no tools — you keep your existing shower head.
Best for: Anyone who wants filtered water but loves (or is renting and can't change) their current shower head.

Rain Shower

What it is: A wide, fixed overhead rainfall shower head with filtration built in.
Install: Replaces your existing fixed shower head.
Best for: People who want a generous, rainfall-style flow and filtration in one fitting.

Shower Head 2.0

What it is: Our standard handheld filtered shower head.
Install: Replaces your existing handheld head and screws onto the hose — no tools needed.
Best for: Anyone who wants a straightforward handheld filtered shower head.

Shower Head+

What it is: Our intelligent handheld filtered shower head. It filters exactly like the 2.0 but adds smart tracking: it monitors your water use and filter life, shows it in the app, alerts you when the filter needs replacing, and tracks your water temperature to warn you when the water is hot enough to stress your skin.
Install: Same as the 2.0 — replaces your handheld head, no tools needed.
Best for: People who want filtered water plus data on their usage, filter life and shower temperature.

A quick note on refills: the Shower Filter and Rain Shower share the same Refill Capsule, while Shower Head 2.0 and Shower Head+ share the same refill cartridge. So if you're choosing between products, you're also choosing which refill you'll reorder.

Not sure which suits your bathroom? Message us and we'll help you pick.

Both filter your water in exactly the same way and use the same refill cartridge, so the water you shower in is identical.

Shower Head 2.0 — our standard handheld filtered shower head. Straightforward, no app, no electronics.

Shower Head+ — our intelligent version. On top of the same filtration, it:

Monitors your water usage and tracks how much filter life you have left
Shows all of this in the app
Alerts you when the filter is spent and needs replacing, so you're never guessing
Tracks your water temperature and warns you when the water is hot enough to stress your skin (very hot water can dry out and irritate skin)

Because they share the same refill cartridge, switching between them later doesn't change which refill you reorder.

In short: choose the 2.0 if you just want clean, filtered water in a simple handheld head; choose the Shower Head+ if you also want to track your usage and filter life and get a heads-up on water temperature.

Every Hello Klean filter is made up of multiple filtration layers, each designed to target a different aspect of harsh water.

Coconut-shell activated carbon – Reduces free chlorine, along with the taste and odour that come with it. Activated carbon is one of the most established and widely used filtration materials (ref. 1; ref. 2).
Calcium sulphite – Reacts with free chlorine and neutralises it into harmless chloride using the same process relied on in mains-water dechlorination (ref. 3).
KDF copper-zinc media – An established redox technology that helps reduce free chlorine and certain dissolved heavy metals, including lead and mercury. Unlike carbon alone, KDF continues to perform effectively in hot water and at higher flow rates.
Antiscaling media – Helps reduce limescale build-up, keeping both your shower and fittings cleaner for longer.

Every filter is independently RoHS-tested and verified free from restricted heavy metals, so it reduces what's in your water without adding any metals of its own.

Like any carbon filter, performance naturally decreases over time and can begin to harbour bacteria if left for too long (ref. 4). That's why we recommend replacing your filter every 3 months.

1.0 is our older generation. We've since improved both the design and the filtration on the 2.0, but plenty of 1.0 products are still in happy use — so we continue to sell 1.0 refill cartridges and you don't need to replace your whole shower head to keep it running.

The surest way to get the right refill is to contact us with your order number. We'll look up exactly which product you have and make sure you get the correct refill — no guesswork. If you no longer have your order number, just send us your name and the email or address used on the order and we'll find it.

If you're reordering a refill and aren't certain which generation you're on, reach out before you buy and we'll confirm it for you.

Our filters are independently tested by SGS, one of the world's leading laboratory testing organisations.

On a fresh cartridge, SGS measured over 99% free chlorine reduction using the standard 2.0 mg/L test concentration. As with any filter, performance gradually decreases over time, but throughout SGS's full service-life testing, chlorine reduction remained above 96%.

Because chlorine levels in typical UK and EU shower water are much lower (around 0.2–0.3 mg/L), most households stay within this high-performance range throughout our recommended 3-month replacement cycle (see "How often should I replace my filter?").

Our filter media is also independently tested to EU RoHS standards and verified free from restricted heavy metals, including lead, mercury, cadmium and hexavalent chromium, meaning it doesn't add these metals to your water.

Beyond filtration, our products are built to meet rigorous quality standards. Shower Head 2.0 meets the EN 1112 European safety standard for shower fittings, while Shower Head+ is RoHS tested, achieves the highest grade in a 200-hour salt-spray corrosion test, and is built to WEEE recyclability standards (approximately 77% recyclable and 90% recoverable).

Not in the same way as a traditional water softener.

A water softener removes the calcium and magnesium that make water hard, usually for your entire home. Our filter doesn't remove those minerals, so your water's hardness level stays the same.

Instead, Hello Klean is engineered to reduce the effects of harsh water on your hair and skin.

Our multi-stage filter significantly reduces free chlorine, while CRS is used for scale control to help reduce the mineral deposits left behind on your hair and skin.

CRS (used in our Shower Heads) is a plant-derived, amino acid-based scale inhibitor that binds to calcium and magnesium, keeping them dispersed in the water rather than allowing them to crystallise and form limescale. It delivers a minimum of 82% scale inhibition across 8,000 litres, helping reduce the buildup that can leave hair feeling rough, skin feeling dry and shower surfaces coated in scale.

So while your water isn't technically softer, the result is water that feels noticeably gentler on your hair and skin.

If your goal is preventing limescale throughout your home, you'll need a traditional water softener. If you're looking to improve the quality of the water you shower in — and reduce the effects of harsh water on your hair and skin — Hello Klean is a simple, renter-friendly solution.

It takes about two minutes by hand, with no tools or a plumber needed. Unscrew your current shower head or hose and screw the Hello Klean unit onto the standard 1/2-inch (G1/2) shower fitting. Step-by-step guides are on our Installation and Fitting guide pages.

Our products use the standard UK and EU 1/2-inch (G1/2) shower fitting, which fits the large majority of showers. The Shower Filter sits in-line, so it works with most existing hoses and heads. If you have a non-standard or older fitting, check our Fitting guide or contact us before ordering and we will help you confirm compatibility.

No. Our Shower Filter, Rain Shower, and Shower Head can be installed by hand in about two minutes, with no tools or plumber needed.

No, our Hello Klean Filtration range won’t affect your water temperature. The filters are designed to maintain your water's flow rate and pressure, ensuring that your water temperature remains consistent during your shower.

Yes, our Hello Klean Filtration range is compatible with electric heaters and can be installed without issue. However, because different heaters have varying flow requirements, we recommend checking with your heater's supplier or manufacturer beforehand to ensure optimal performance. This way, you can be sure everything works smoothly together.

Our shower heads are engineered to keep a strong, satisfying flow, and most customers say the pressure feels great or even better. Filtered media can slightly affect flow on very low-pressure or gravity-fed systems. If that is your setup, contact us and we will recommend the best option.

A small drip at a new connection is almost always the washer. Make sure the rubber washer is seated flat in the connector, hand-tighten firmly without cross-threading, and add a little PTFE (plumber's) tape to the thread if needed. If it still leaks, send us a photo and we will sort it out quickly.

Replace your filter every 3 months to keep filtration performing at its best.

If you have a larger household, shower more frequently, or live in a hard water area, you may need to replace it sooner. As with any carbon filter, performance naturally decreases over time and bacteria can begin to harbour if left for too long (ref. 1), so changing your cartridge or capsule regularly is important.

The 2-piece Refill Cartridges fit the Shower Head and Shower Head+. The Refill Capsule fits the Shower Filter and the Rain Shower. If you are unsure which you have, contact us with your order number and we will point you to the right one.

We have improved our filters over time, so refill fit depends on which generation of device you own. If a refill does not fit your head, do not worry. Send us your order number and we will make sure you get the correct refill that fits, with no hassle.

Refills are £40 and last 3 to 4 months, which works out to roughly £10 to £13 a month, or under 50p a day, for filtered water at every shower. A Smart Refill plan saves versus one-off pricing and reorders automatically, so it is more like replacing a daily skincare product than a one-off gadget.

Yes. Our refillable system uses far less plastic than disposable filtered heads, and our Shower Head+ is designed so around 77% can be recycled and 90% recovered at end of life, meeting EU WEEE environmental standards. See our Sustainability page for more.

Our Smart Refill Plan takes the hassle out of remembering when to change your filter. You’ll get fresh capsules delivered every 3 months to ensure impurities don’t creep back in and disrupt your routine.
