Reverse osmosis is an amazing technological innovation that converts seawater into drinking water in areas around the world where freshwater is in short supply. It's also highly effective at cleaning contaminated wastewater in industrial settings. It can be a good option for household water under certain circumstances (e.g. kidney failure). However, in most cases mains water is safe to drink, and a high-quality activated carbon tap filter will give you great-tasting drinking water at a lower cost and with less

Few things are as annoying as being thirsty and going to the kitchen to get water, only to find that someone has forgotten to fill the filter pitcher. TAPP users never have that bother, however, because their filtered water comes straight from the tap. And it comes out instantly, with the ability to choose between filtered and non-filtered water with just the turn of a small switch. Our tap water filter lasts 3 times as long, filters 15 times as much water, and uses advanced technology to eliminate even microplastics and heavy metals. Because of this, the water tastes much better. In addition, our annual subscription is cheaper than the most popular filter pitchers. And with filter pitchers, the cartridge has to be changed every month. Here's a comparison table:

In that case, you're covered by our guarantee. We understand that it can take about 2 weeks before some products are fitted.

Each TAPP 2 filter highly effectively removes the chemicals from 1200–1500 litres of water (depending on original water quality), the equivalent of 3 months of average household water usage. We recommend replacing the cartridge after 3 months even if you haven't filtered 1200-1500 litres. This is because the filters become saturated with contaminants over time and there is a risk of bacterial growth after 3 months. This happens with all activated carbon filters.

Bottled water is no healthier or safer than tap water. What's more, plastic water bottles' value chain has a massive environmental footprint.

TAPP Water filters are designed to provide tasty clean tap water from public water sources. This means most tap water in Europe and North America as well as many other countries. Our blog also provides information about tap water in many places around the world.

Calcium is a mineral with recognized health benefits and isn't considered a contaminant. Calcium produces limescale when it combines with magnesium carbonates. TAPP 2 filter cartridges effectively minimize limescale concentration for the first month of use. From the second month onwards, limescale reduction is less efficient, though the filters remain just as efficient at removing impurities like chlorine, microplastics and nitrates, among others.

As parents, we all want what's best for our babies. Two of TAPP Water's co-founders recently became parents, and they spent a lot of time researching this issue before coming to a decision. 

Our filters remove unpleasant tastes and smells, as well as chlorine, microplastics and over 80 other water contaminants. What's more, they maintain essential minerals like calcium, potassium and magnesium.

Your annual subscription consists of a first delivery of the housing and 4 cartridges that will give you 12 months of filtered water. Remember, you have to change the cartridge every 3 months to maintain water quality. At the end of the 12 months, your subscription will automatically renew. That means you'll receive 4 new cartridges for $690 a year after having made the first purchase. One week before your subscription renewal is due we'll send you an email reminder with the option of cancelling or suspending your subscription.

Our system is compatible with 95% of round taps with threaded spouts (which is what the filter attaches to). It isn't compatible with round taps with extendible hoses, or with any of the following models: 

Yes, the TAPP 2 activated carbon block with its 1–2 micron mesh removes all microplastics found in tap water so far. 

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 to achieve a real impact.

It's not advisable to use the filter with hot water. The materials in the replacement cartridge's housing aren't designed to withstand high temperatures and may melt. If you need hot water, simply twist the lever and use the water without filtering it.

Activated carbon filters are capable of working miracles, or near enough. They successfully remove contaminants and unpleasant smells and tastes from tap water. But how do they work and do you need one? Here's a simple overview of how active carbon filters work, what they remove and the limitations.

It's safe and healthy to drink and also much cheaper than bottled water. Tap water in Europe and North America is subject to regular and rigorous controls. TAPP filters remove substances found in distribution networks (like heavy metals in areas with old pipes), as well as chlorine, which can often make water taste unpleasant. What's more, filtered tap water is more environmentally friendly than bottled water. Bottled water's CO2 footprint comes not only from its production, but also from its transport and distribution. And finally, but no less importantly, TAPP filters make life so much easier, as you no longer have to carry heavy bottles of water home from the supermarket.

All TAPP Water products are tested and certified according to strict independent lab standards and NSF specifications you can see the lab results.

Yes, really easy. Installing the filter takes less than a minute — simply screw it onto the tap nozzle. Installation is explained in detail in the section "How do I install it?" on the TAPP 2 Click and TAPP 2 Twist product pages.

No, you don't need to remove the filter. All you need to do is twist the little lever on the side of your filter to switch between filtered and unfiltered water.

TAPP 2 uses highly-effective activated carbon block technology that eliminates more than 80 contaminants and reduces another 50. Minerals, which are good for our health, stay in the water. The primary chemical elements that are removed or reduced include: - Microplastics - Lead and other heavy metals that may be shed by old pipes - Chlorine and its by-products, which contribute to tap water’s unpleasant taste and smell - Volatile organic compounds (VOCs), such as THMs and PFCs - Pesticides - Cryptosporidium (or Crypto parasites) TAPP 2 also reduces, but doesn't fully remove, arsenic, nitrates, chromium and medicines. TAPP 1 uses granulated activated carbon (unlike TAPP 2, which uses a block of activated carbon) and filters out 70 contaminants (excluding microplastics)
