Why Is It Important?
This Is Where Your Water Comes From
Tap water flows through aging, corroded pipes, collecting bacteria, harmful germs, and dangerous contaminants before reaching your glass. Why? Because of outdated infrastructure and years of neglect in municipal water systems.

ANTI-BACTERIAL ACTION
Stops bacteria and viruses, preventing serious gastrointestinal illnesses and infections.
I was born in Aragón, the same name the company uses to refer to the material this cartridge is made of. It makes tap water taste clean and pure. And on top of that it may even stop PFAS. I strongly recommend it.
Very simple to assemble, compact, aesthetically pleasing. The aerator included in the kit does not seem well made to me, it is certainly an annoying oversight, but the fact of being able to mount in its place what must be removed from the tap in order to mount the filter is decisive. The jet of filtered water is definitely too powerful, you have to get used to opening the tap carefully so as not to splash all around. The technical data say that optimal filtration is achieved with a flow of 0.5 liters per minute: it is unthinkable that such use would be made. However, the improvement in flavor is incontrovertible. We will see the consistency of yield over time.
I like its size and faucet style (it looks like a "tap"). My water used to come through the tank and looked not so pure. With this filter, it has improved significantly.
I had installation problems due to my faucet, which has the correct dimensions, but the space to screw it in was too limited because of a curved surface. The customer support was very kind and efficient, and with their help, I was able to install the product. The water has a good taste. Aesthetically, it is far superior to products from other brands, as it matches the color of the faucet and has a compact size.

Frequently Asked Questions
Which contaminants does your filter target?
Geyser water filter removes up to 99.9% of tap water contaminants for your health and safety. Remember, the majority of typical carbon or charcoal filters target as few as 5 contaminants.
Here are just a handful of the contaminants we target:
- Chlorine: Can produce harmful disinfection byproducts.
- Lead: Linked to learning disabilities and nervous system damage.
- Fluoride: Overexposure can cause bone and dental issues.
- PFAS/PFOA/PFOS: Known as "forever chemicals" and linked to numerous health concerns including cancer.
- HAA5 & TTHMs: Byproducts connected to various cancers.
- Perchlorate: Found in explosives and can affect the thyroid.
- Nitrate: Linked to cancer and thyroid issues.
- Arsenic: Naturally found and linked to several cancers.
- Chromium 6: A heavy metal linked to liver damage and cancer.
How long does your filter last?
Usually 3 to 4 months, but it really depends on your water!
Technically, a single cartridge can last up to 6 months if you're among the lucky few with cleaner water. From our experience, if you live in older homes or buildings or get water from wells, you may need to replace your cartridge more frequently. A good sign to change it is when you start to notice a drop in water pressure.
How much is the filter replacement?
€29.90 for 1 replacement. But when you subscribe, it's €26 (10% off).
We sell our filter cartridges in packs as well, and it will be even cheaper — starting from 20 cents per day with subscription. With a subscription, you are billed every 3 months, but you are free to modify or cancel your subscription at any time. Depending on your water quality, a single cartridge could last you up to 6 months! If you're lucky enough to have cleaner water, you can contact us to adjust your replacement delivery frequency.
