Frequently Asked Questions

Cleansii is a high-performance shower filter that removes chlorine, heavy metals, and mineral deposits from your tap water. It attaches to your existing shower and helps protect your hair, skin, and scalp from the damaging chemicals in unfiltered water. You will feel the difference from the first shower.

Cleansii removes chlorine, heavy metals (such as lead, mercury, and copper), sediment, rust, and mineral deposits. It uses a concentrated combination of KDF-55, Calcium Sulfite, and Coconut Activated Carbon in a true multi-stage system. Each filtration stage contains enough material to actually be effective, unlike cheap filters that use tiny amounts of many different materials.

Most cheap filters stuff 15 random materials into a small cartridge, which means each material is present in such a tiny amount that it cannot filter effectively. Cleansii uses concentrated doses of proven filtration media. The difference is simple: we use enough of the right materials to actually work. If you have tried a cheap filter before and it did nothing, that is exactly why.

Most customers notice softer water from the very first shower. In the first week, the water feels noticeably different. By week 2 to 3, your hair starts feeling softer and less brittle. By week 4 and beyond, you will see visible improvements in shine, volume, and skin hydration. Results vary depending on your local water quality, but the majority of customers report noticeable changes within the first month.

No. Our high-density stainless steel mesh and optimised internal design maintain your water pressure. Many customers actually report their shower feels stronger after installation because the mesh creates a more focused stream.

No. Cleansii has no subscriptions, no auto-renewals, and no surprise charges. Ever. When you need a replacement filter, you simply order one from our website whenever you are ready. No traps, no fine print, no "cancel within 48 hours" policies. Your money, your decision, your timeline.

We currently sell the Cleansii Flow (our main shower filter that installs between your wall pipe and showerhead) and the Cleansii Handheld Shower (a complete filtered handheld showerhead). Both products use the same concentrated multi-stage filtration system. Replacement filters are also available separately.

Three signs to look for. First, the chlorine smell disappears immediately. Second, the water feels physically softer on your skin from the first shower. Third, after 2 to 4 weeks your hair and skin start responding differently to your existing products. And if you open the used filter after 3 months, you will see exactly what was going into your hair. It is usually brown and full of sediment.

Cleansii fits 99% of all standard shower connections worldwide. It uses the universal G1/2 inch thread, which is the industry standard in Europe, the US, UK, Australia, and most other countries. If your showerhead screws on and off, Cleansii will fit.

No. Installation takes under 3 minutes and requires zero tools. Simply unscrew your existing showerhead, screw on the Cleansii filter, then screw your showerhead back on top. That is it. No plumber, no tools, no technical knowledge needed.

No. Cleansii does not modify your plumbing in any way. It simply screws on between your wall pipe and showerhead, like an adapter. When you move out, unscrew it and take it with you. Your shower is exactly as it was before. No marks, no holes, no changes.

In the rare case that Cleansii does not fit your specific shower connection, you can return it within 30 days for a full refund. No questions asked, no hassle. Contact us at hello@cleansii.com and we will arrange everything for you.

Yes. Simply unscrew it from your current shower and install it at your new home. Takes less than a minute. Your filter cartridge stays inside and continues working where it left off.

Yes. As long as your rainfall showerhead uses a standard G1/2 inch thread connection (which most do), Cleansii will fit perfectly. It installs between the wall pipe and the showerhead arm.

Most tap water contains chlorine (the same chemical used in swimming pools), heavy metals like lead and copper, and dissolved minerals that cause hard water. Chlorine strips your hair of its natural oils, leaving it dry, brittle, and frizzy. It also damages your skin's moisture barrier, causing tightness, dryness, and irritation after every shower. No amount of expensive shampoo or moisturiser can fix damage that your water causes every single day.

If you notice white or chalky buildup on your taps, showerhead, or glass doors, you have hard water. Other signs include: your skin feels tight or dry after showering, your hair is frizzy or flat regardless of products, soap does not lather well, and you see a film or residue on surfaces. Most cities in the UK, US, and Australia have moderate to hard water.

Many customers with eczema, psoriasis, and dry skin have reported improvements after using Cleansii. Removing chlorine and heavy metals from your shower water reduces irritation and allows your skin to maintain its natural moisture barrier. However, we are not a medical product and cannot make medical claims. If you have a specific skin condition, we recommend consulting your dermatologist. Our 30-day guarantee lets you try it risk-free.

Cleansii reduces the effects of hard water by filtering out dissolved minerals, chlorine, and heavy metals. While it is not a full water softener (those are installed at your main water supply), it significantly reduces the harsh chemicals and minerals that cause the most damage to your hair and skin during showering.

Cleansii is designed for bathing and showering, not for producing drinking water. While it removes chlorine and heavy metals, it is not certified as a drinking water filter. For drinking water, use a dedicated water filter designed for that purpose.

This is actually the most common situation for our customers. You invest in great products, but they cannot work properly when your water undoes the benefits every time you shower. Cleansii does not replace your products, it makes them work the way they are supposed to. Many customers find they use less product and get better results once their water is filtered.

Every 2 to 3 months for best results, depending on your water quality and how often you shower. You will notice the water starting to feel different when it is time for a change. We recommend setting a simple reminder for yourself.

Replacement takes about 30 seconds. Simply unscrew the filter housing, remove the old cartridge, insert the new one, and screw it back together. No tools needed. It is designed to be as simple as possible.

Replacement filters are available on our website at cleansii.com. Simply visit our shop, add a replacement filter to your cart, and place your order. Free shipping included, as always.

No. There is no subscription and no auto-renewal. When you need a new filter, you order one yourself. No one will charge you automatically, send you products you did not ask for, or make you jump through hoops to cancel something. This is a deliberate choice. We believe you should decide when and if you want to reorder.

The filter will gradually become less effective as the filtration media gets saturated. Your water will not become harmful, but you will start noticing the chlorine smell returning and the water feeling less soft. The filter will not break or cause damage to your shower, but for the best results, we recommend replacing it every 2 to 3 months.

Yes. When you open the used filter cartridge after 2 to 3 months, you will see that it has turned brown and is full of sediment, rust, and debris. This is everything that was going into your hair and onto your skin before you installed Cleansii. Many customers share photos of their used filters, and it is eye-opening to see what unfiltered water actually carries.
