It’s safe and healthy to drink and also much cheaper than bottled water. Public tap water in Malta is subject to regular and rigorous controls. TAPP water filters additionally remove any contaminants as well as chlorine which is often the origin of poor tasting water. Filtered tap water is much more environmentally friendly than bottled water. Just consider the CO2 footprint of bottled water production, transportation and distribution. And last but not least, using a TAPP faucet filter is more convenient, as you can stop carrying heavy water bottles from the supermarket home.

How do I know when to replace the refill cartridge?

You can register your TAPP2 Twist in the MyTAPP app if you like. But you can also just twist the calendar to set it to 3 months from today (or the day you replace the refill cartridge). The filter has a calendar on it, which reminds you of when you need to replace the cartridge.

Will the filter fit on my faucet at home?

Yes. TAPP filters are designed to fit on most standard faucets (Metric: M22x1 or US: 55/64’’-27). In general, you will have to remove the aerator (small device at the faucet tip) from your faucet before you can screw on the filter. In any case, TAPP 2 comes with two additional adapters (Metric: M20x1 and M24x1 or US: 13/16’’-27 and 15/16’’-27). In the unlikely case that the included adapters do not do the trick, please get in touch with us and we will be happy to help you out. Also, if your faucet does not have an aerator, please contact us for more information at hello@tappwater.mt.

TAPP 2 refill cartridges are entirely made out of non-toxic materials which remain inert after decomposing. The cartridges contain a high percentage of biodegradable and compostable material and can be disposed of with organic waste. This organic waste ends up in an industrial composting plant where the cartridge breaks down within 1-2 months. Alternatively, it can be discarded with general waste, where it will break down within a couple of years in a landfill or be burned without causing any plastic residue. It will also take a couple of years to break down in a garden compost, so not recommended.

Note, that the device itself (without the refills) is made out of highly recyclable ABS polymers, and can be disposed of with plastic waste.

Why is TAPP 2 better than other filters?

– TAPP 2 uses the highest quality coconut shell-based carbon-block filter, used for maximum filtering of chemicals and improvement of taste. This was selected after testing over 40 different variants and building on from our original TAPP 1 filter.
– TAPP 2 delivers more clean filtered water for the money than any pitcher, on-the-counter reverse osmosis or faucet filter available on the market today.
– TAPP 2 is the only filter with biodegradable refill cartridges.
– Customer trust and safety is always our first priority. All product claims and information about TAPP filters are based on scientific facts and testing.

We want to make it easy for you. When buying your refills for TAPP 2, you can opt for the yearly service model for 60 euros. You will then receive 4 refill cartridges in order to ensure a constant and uninterrupted supply with fresh and clean tap water. After one year you’ll automatically receive 4 more cartridges, and your credit card or PayPal account will be charged with 60 euros. Please note that, apart from the convenience, the yearly service model also means saving money, as a set of two replacement cartridges normally costs 39 euros.

Yes, of course. Just send an e-mail to hello@tappwater.mt, indicating your e-mail address and we’ll cancel it for you. You can also cancel directly in your user account area in MyTAPP.

Not yet. We are starting conversations with retailers in Malta and will update our website as new information is available. If you wish to stock TAPP2 in your store Just send an e-mail to hello@tappwater.mt and let's talk!

Based on tests performed on the type of activated carbon block used in TAPP 2 pharmaceuticals are reduced by 95% or more. This includes: Hormones: prednisone, prednisolone, progesterone, testosterone and cortisol Antibiotics: ciprofloxacin, used to prevent certain infections caused by bacteria, as well as sulfamethoxazole and trimethoprim, which are used to treat a wide variety of bacterial infections including pneumonia, and urinary tract and intestinal infections Antidepressants: fluoxetine, prescribed to treat a variety of conditions, including depression and other mental/mood disorders Anti-anxiety medication: meprobamate, a treatment used to relieve nervousness or tension that exceeds stress of everyday life Painkillers: ibuprofen and naproxen Additional tests will be performed during 2020 to confirm these results.

TAPP 2 reduces Chlorine by 95% or more based on 100s of tests carried out on tap water around the world. This improves the taste instantly for chlorinated water. In addition to this TAPP 2 removes all known bi-products from Chlorine (whereof some potentially cancerogenic such as THMs).

Yes, TAPP 2 reduces Chloramine by 95% or more based on more than 50 tests carried out on tap water in Los Angeles and other cities using chloramine rather than Chlorine. In addition to this Amonia is reduced by 90% or more.

TAPP 2 is tested for lead reduction and removal in accordance with NSF 53. This means lead is reduced by 95% or more.

TAPP 2 removes all microplastics that have been found so far in tap water thanks to the 1-2 micron carbon block. 

TAPP 2 reduces Nitrate by 90% or more based on independent lab tests.

TAPP 2 reduces Nitrate by 90% or more based on independent lab tests.

TAPP 2 reduces fluoride by 30-70% based on independent lab tests. Fluoride is a natural compound found most fresh water sources, tea, vegetables and fruit. It’s not considered a contaminant although we are aware that some people are concerned about the health effects. Many water filters claim fluoride removal but in reality we’ve found that reverse osmosis is the only effective way to reduce fluoride by 95% or more.

TAPP 2 is not certified for arsenic removal but in the tests where arsenic was detected before filtering more than 70% was removed. The maximum concentration level recommended by EPA and WHO is 10 mg/l. Therefore the results mean that for any tap water with 50 mg/l or higher concentration of arsenic alternative solutions should be considered.

Calcium is considered a mineral with health benefits and not a contaminant. Unfortunately calcium also has the unfortunate bi-effect of causing limescale in combination with magnesium carbonates. The standard TAPP 2 filter only marginally reduces calcium and can therefore not be considered effective in limescale removal.

What is TAPP 2 made out of? Why is it biodegradable?

TAPP 2 refill cartridges are entirely made out of non-toxic materials which remain inert after decomposing. The cartridges contain a high percentage of biodegradable and compostable material and can be disposed of with organic waste in Malta. The device itself (without the refills) is made out of highly recyclable ABS polymers.

Our work at TAPP is transformational but simple, we create solutions that aim to help reduce plastic waste. Innovation is difficult and rarely perfect, but we continue to work on improving our products every day to reach our goal of providing top quality plastic-free alternatives – which allow others to join our mission. We created our biodegradable refill cartridge filters to support this purpose, and it wasn’t easy to reach a threshold of 76% total biodegradability. In fact, it was very difficult, and it represents a substantial advancement for filter cartridges – the most eco-friendly option in this category. We have also taken great care to ensure the remaining 24% of the filter cartridge is non-toxic, inert and will not harm the environment or marine life. We continue to innovate and are committed to creating a 100% biodegradable filter – as biodegradable is always better than relying on recycling. Better for the planet, better for our children and better for ourselves. We know we are on the right path by having created a better solution available right now compared to what existed before.
