EcoPro filter refills

The refill is the part that filters the water – it’s the only piece you’ll need to replace every 3 months to prevent the build-up of substances and blockage of the filter.

El cartucho reutilizable contiene el bloque de carbón

Limescale, chlorine (the cause of the unpleasant taste), sand, rust and sediments, lead, mercury, salmonella, legionella, pesticides, herbicides, medication waste, nitrates and other substances > 1-2 μm (micrometres)
The refills, made of activated carbon, use 5-step Ultra-Advanced Microfiltration technology to filter more than 100 substances from tap water while retaining the essential minerals in the original water.
Replace the refill with a new one 3 months after its first use. To do so, unscrew the used refill and screw on a new one. See video
You’ll receive an email reminder 7 days before the change date. In addition, EcoPro has a rotating cap that allows you to manually indicate the month and week you started the cycle.

Dimensions: 12.4 x 7.4 x 10.9 cm Weight: 363 g
A. Filter housing B. Lever (filtered/non-filtered) C. Cartridge housing D. Carbon block C + D = cartridge
  • Only run hot water through the filter when the lever is set to NON-filtered.
  • Do not wash the filter with soap.
  • If you haven’t used the filter for several days, run the water through it for 20 seconds before using.
  • Do not expose the filter to heat.
  • The carbon block must be changed every 3 months. Learn why here
  • When the cartridge expires, the TAPP2 Twist filter housing can still be reused. Remove the carbon block from the housing and insert a new one. Re-attach the cartridge and enjoy filtered water for another 3 months.

The rotary top indicates the week in which you replaced the cartridge. It rotates manually. The numbers indicate the months and the dots indicate the weeks. Check this page.

TAPP 2 Twist uses advanced 5-stage activated carbon ultra-microfiltering.

The activated carbon block inside the cartridge is made from coconut shells and absorbs chemicals, gases, metals and organic elements thanks to its microscopic structure and highly porous surface.

As the water passes through the filter all the contaminants are trapped by the spherical activated carbon particles. The result is clean, ready-to-drink filtered water.

Filtering rate: 4 l/min (15 seconds to filter 1 litre).

Cartridge duration: 3 months from first use

Cartridge filtering capacity: up to 1,200 litres (approx. 13 litres/day) over 3 months

Carbon block density: 1–2 µm

Substances removed: 100+


The materials we use in our filters reflect our commitment to sustainability, quality and durability.

The cartridge housing is made of ABS and PC plastic, which is free of BPA and phthalates and is manufactured from natural raw materials.

The carbon block found inside the cartridge housing and which filters your water is made of coconut shells (70%) — which biodegrade in CO2 and water — and UHMW (30%) — which is inert and stable and doesn’t accumulate in marine life.

Our product also contains two small silicone parts that hold the carbon block in place to ensure maximum filter efficiency. These parts decompose in amorphous silica, carbon dioxide and water.

We guarantee that our system is compatible with 95% of round threaded taps. The non-compatible commercially available taps are shown below: img-wrap

Our filters remove unpleasant tastes and smells because they filter out chlorine, which is what causes them. Moreover, removing microplastics and over 100 contaminants helps ensure your water tastes solely of what it should: pure clean water.

Because the quality of your water and the efficiency of the filter’s filtration capacity can only be guaranteed for a usage capacity equivalent to 3 months. Our quality parameters for filtering substances and contaminants are above 95% in most cases (depending on the type of contaminant it is higher, for instance, with chlorine filtration efficiency is at 99%). The filtration of contaminants such as pesticides and herbicides, VOCs, and microplastics don’t meet our quality parameters after 3 months of usage. If you use your cartridge beyond 3 months, filtration efficiency will decay below our minimum standards. Besides the mentioned absorption and efficiency aspects, also keep in mind that carbon is an organically based material that provides a breeding ground for microorganisms on which bacteria can multiply over time. These bacteria build up behind the filter and contaminate the water in the pipe system. This is normal for all activated carbon filters, regardless of whether you live alone or with many people, or if the filter hasn’t been used for some time. A little bit of advice: if you haven’t used your filter for a few days, let the water run through it for 30 seconds before drinking to flush out any bacteria that may have built up here for more information.

After analysing the various materials and solutions available, we chose the type of plastic we use because it’s the best option in terms of durability (meaning it’s also the best in terms of sustainability). At TAPP Water, sustainability is at the heart of everything we do. As well as reducing the number of plastic bottles used by customers who install our filters, we’re also perpetually evolving and questioning the choices we make about materials and transport. In short, we’re constantly looking at how to ensure that our value chain has the best possible impact on our planet. We know that we still have a long way to go and many challenges to overcome. But we’re especially proud of:

The materials we use to make the main part of the product (the filter itself) are long-lasting, highly recyclable and free of BPA and phthalates.

The materials used in the replaceable part of the product (the cartridges) are mostly naturally occurring and biodegradable, although they aren’t treated as such in composting plants.

The block of activated carbon inside the cartridge — which is what filters the water — is made of coconut shell. This means that your water passes through a natural, organic material.

Why don’t we use stainless steel? For the moment, our aim is to create a solution that, in addition to being sustainable and easy to use, is also affordable. It has to be a solution that saves households money when compared with buying bottled water. Making the filter out of stainless steel would create a solution that would only be affordable for a few users, and at TAPP Water we want to make our products affordable for all and to reach as many households as possible so as to achieve a real impact.

Yes, of course you can safely remove the filter from one tap and fit it to another one! The thread quality allows you to change tap repeatedly — when you move house, when you go on holiday, etc. You can take your TAPP Water filter with you when you travel and even use it in hotels!
Our filters are able to filter the tap water in 99.5% of Spain where the mains water has passed the local authorities’ potability tests. In the case of wells or private water tanks TAPP Water cannot guarantee water potability. Our activated carbon filtering technology removes over 80 water contaminants, among them chlorine (the main cause of tap water’s unpleasant taste), microplastics, lead, nitrates and nitrites (only measurable using special lab equipment).

    Easy to install, water taste better, I don't buy water bottle anymore

  • The best water solution to improve water taste!

    I live in East Sussex, UK, the tap water in our county is hard water and doesn't taste well, so we are usually buying bottled water. After an easy installation, the water now tastes really well and we do not need to buy bottled water anymore. TAPP Water Filter was easy to install and we are very happy with the results. Great solution and I will happily recommend to other people in my area.

  • Turn knob is easy to work with and sturdy (unlike the Brita one)

    This came to replace leaking Brita filter and did immediately fit, no complications. Turn knob is easy to work with and sturdy (unlike the Brita one). Water quality is good, hopefully does the job exactly as it says on tin (since I have no lab at home to prove or confirm what the manufacturer says). But seems like a great product

  • Clever and robust

    This is a very clever, well-made device and definitely worth the money. The water certainly tastes better coming through the filter here in hard water Warwickshire and the bypass switch is most useful. You won't regret purchasing this.

  • Brilliant little gadget

    Amazing. Easy to fit and has revolutionised our water drinking in the household. I could never stomach south-east England tap water, revolting. I now drink glasses of water straight from the tap. Fantastic product.
