TAPP: IN LOVE WITH TAP WATER

What if tap water is potable, but not very tasty? Use a water filter! It’s almost one year ago since we tested the TAPP 2, a simple and affordable biodegradable water filter. Since then, TAPP Water has been working on the development of new products and their website. Time for a close look at this innovative company. Oh and we have a nice present for you at the end of this blog!

BECOMING TRUE WATER GEEKS

The TAPP team is growing fast. And so does their knowledge. They consider themselves to be ‘water geeks’. We like the fact they share valuable info on their website, e.g. about different filter mechanisms and tap water quality around the world. For example Can I drink tap water in Ibiza? Or in Hong Kong? The website also has a 3-minute water filter type test’ ☺.

MISCONCEPTIONS ABOUT TAP WATER

The 25 team members gained lots of insights regarding misconceptions about tap water. Silvia Gennaro (PR, Affiliation & Partnerships Manager) shared a few stories with us. For example many universities are engaging with their students giving them reusable bottles to refill and avoiding single-use plastics. However in countries where these universities are, many still refil the reusable bottle with water that comer from plastic bottles. (e.g. using 1,5 L single-use plastic bottles from the supermarkets).

Silvia: “Italy has extremely pure water sources. It’s even famous for exporting bottled spring water, like San Pellegrino. However, Italy is the world’s 3rd country when it comes to bottled water consumption per capita (after Mexico and Thailand), the first one in Europe. Tap water tests in Milan and Rome show the water is very clear and safe, yet people buy bottled water because they have false beliefs.”  

Furthermore Silvia told us some people believe they get kidney stones from drinking tap water, even though many studies show it is not true. Overall, tap water provides a perfect mixture of sodium, magnesium, potassium and calcium. Even more strange: healthy humans buying low mineralisation bottled water and mineral supplements! Strange!

TESTING FILTERED TAP WATER

Last month, TAPP demonstrated their water filters on a local food and artisan market in Barcelona, their hometown. During the event, they conducted blind-tests with filtered and non-filtered tap water. Visitors were amazed by the difference in taste. “Amazing!” “It tastes really good, I’m going to buy it”. Something we also concluded with our own user test (50 participants).

GET YOUR OWN WATER FILTER – SPECIAL OFFER

All in all, we feel TAPP is a cool company striving for big changes. They really want to re-educate people in the way we consume and drink water. Most importantly, they offer sustainable, affordable water filters. The TAPP 2 is a biodegradable water filter (Activated Carbon Block, 1-2 microns) that you connect directly to the faucet. It strongly reduces bad taste, chlorine, lead, microplastics and a wide range of other contaminants.

USING A STERIPEN ADVENTURER OPTI TO STERILISE TAP WATER

In this blog I share my experience with the SteriPEN adventurer Opti, which I used when hiking in the Dolomites, Italy. You might wonder, can’t you drink tap water in the Dolomites? Yes, in most places you can. Sometimes directly from the mountain stream. However, there are some areas where tap water is not potable. For example in some mountain cabins also known as ‘rifugio’s’, we could not drink tap water (listed in the end of this blog). Luckily with our SteriPEN we didn’t have to buy any single-use plastic bottles. In this blog, we explain how it works. 

WHAT IS A STERIPEN?

The SteriPEN is a portable gadget which uses ultraviolet light to sterilise water and make it safe for drinking. The device kills the DNA of harmful microbes, viruses and bacteria. According to the manufacturers, 99,9% of all harmful enemies are killed. The SteriPEN does not filter metals or chemicals.

USING THE STERIPEN

Several models exist. We bought the SteriPEN adventurer Opti for our trip. This device only has one button. Click once (for 1 L) or twice (for 1/2 L) to activate the UV light. Then stir around in the bottle until the green light flashes. And done! In case it did not go well, the sensor gives other signals to warn you.

STERIPEN ADVENTURER OPTI PRO’S AND CON’S

What we love about the SteriPEN adventurer Opti:

  • Lightweight: 108 grams + batteries
  • Quick: 48 seconds (1/2 L), or 90 seconds (1 L)
  • Clear interface: green and red lights (unless you are colour blind!)
  • Capacity: can filter 8.000 liters of water
  • Value for money: prices vary from €60,- to €100,- (or around 1-2 cent/litre)

Drawbacks:

  • Battery: you need CR123 batteries, which can be expensive and difficult to find
  • Bottle: you need a bottle with a wide opening, otherwise it does not work

OTHER WATER FILTERS / PURIFIERS

The SteriPEN is one product to purify water. For example there is also the Lifestraw or Grayl water filter. We did not test these, but read what other travellers wrote about this topic:

BACKGROUND INFO: SOME CABINS (RIFUGIO’S) IN THE DOLOMITES WITHOUT CLEAN TAP WATER (BY MACHA LINSZEN)

Our friend Mascha Linszen also travelled to the Dolomites (natural parks around Cortina d’ Ampezzo) and she kept track of tap water conditions in all cabins she visited.

“Most cabins are large and comfortable, and often well connected to civilization by means of a cart track. The comfortable cabins where we have been sitting or passing along the way have running drinking water from the tap at their disposal. In our case this involved the following cabins (DE / IT):

  • Hütte Plätzwiese / Prato Piazza rifugio
  • Dürrenstein Hütte / Vallandro rifugio
  • Sennes Hütte / rifugio Sennes
  • Schutzhütte Vodara Vedla
  • Berggasthaus Pederü
  • Fanes Hut
  • Berghütte Lavarella / Rifugio Lavarella

In some smaller huts the tap water was not drinkable. This was indicated in different ways, and there were alternatives available:

  • Seekofel Hütte / Rifugio Biella
    Indicated: by means of signs (‘kein Trinkwasser’) next to the tap
    Alternative: water / soft drink / alcoholic drink offered for sale
  • Ucia dles Muntagnoles
    Indicated: on arrival, verbal communication by the hostess
    Alternative: water / soft drink / alcoholic drink offered for sale
    Alternative 2: tap water at a nearby larger cabin (Fanes / Lavarella)
    Alternative 3: the host lady (living in the hut) drinks from the nearby stream herself, but clearly indicates that this is at his own risk given the larger huts upstream. Two Germans who, despite this warning, drank from 4 brooks in the brook soon got stomach flu.
  • Ütia da Rit
    Indicated: warm tap water temperature
    Alternative: water / soft drink / alcoholic drink offered for sale
    Alternative 2: there is potable tap water in the kitchen – we asked the cook on the spot if we could fill our bottles.”

WATER FILTER: TESTING THE TAPP 2

Can a simple and cheap water filter be the solution for people to switch to tap water? We tested the TAPP 2 Click during our research trip in Andalusia.

WHAT KIND OF WATER FILTER IS THE TAPP 2?

The TAPP 2 Click is a biodegradable water filter (Activated Carbon Block, 1-2 microns) that you connect directly to the faucet. It strongly reduces bad taste, chlorine, lead, microplastics and a wide range of other contaminants (see detailed description). By using a switch you can choose between filtered water and regular tap water.

The filter works as a kind of printer: the cartridge has to be replaced every three months (or sooner, once you’ve reached >1500 Litres). It is cheap: €89,- for the first year (device + 4 cartridges) and €60,-/year afterwards (4 cartridges).

With a green button on top one can activate a Bluetooth connection and connect the product to the ‘TAPP app’. In the app you can see how many plastic bottles you have saved, and it gives a reminder when to change the cartridge.

THE EXPERIMENT

The TAPP 2 Click was tested in the Lemon Garden Hostel in Seville and Cádiz Inn Backpackers Hostel. A short written explanation – in English and Spanish – was added on how to use the filter.

We observed how people used the filter and asked 50 people about their opinions:

  • In both hostels, we managed to connect the TAPP 2 to the kitchen faucet in only one minute. The product could not be attached to the tiny bathroom faucets.
  • Overall responses were very positive. 45 preferred the taste of filtered water, 4 people could not really tell the difference, and 1 person preferred the taste of unfiltered tap water.
  • About 1/3 stated the filtered water resembled the taste of mountain water.
  • Some participants were confused about the button on top (made to activate Bluetooth connection). They were pressing the button in an attempt to get filtered water, instead of using the switch on the side.
  • Some participants opened the tap too far, causing the water to flow too quickly though the filter (with unfiltered water this is not a problem).

OUR CONCLUSION

We also tried the TAPP 2 Click ourselves and really liked the taste of filtered water. Even though tap water in Cádiz and Seville is relatively good, we could clearly smell and taste the difference. We think the TAPP 2 is a great product in areas where tap water is potable yet not very tasty. When used intensively it also saves money on plastic bottles.

The product is very simple, but a little explanation is desired. Therefore we feel that the TAPP 2 Click is best used in households, small bars, cafés, AirBnB’s and smaller hotels/B&B’s. But not in places where users randomly walk in or out.

GET YOUR OWN TAPP 2

Excited? The TAPP 2 Click has been developed by TAPP Water, a young startup based in Barcelona. Get yourself a nice present and order the TAPP 2. With the coupon code ‘refillambassadors‘ you get €5,- discount on your order at TAPP (apply this code in the first step of the check-out).
