coconut shell carbon Activated carbon is a perfectly natural product and looks like a thin, odorless, tasteless and non-toxic black powder. It can be produced from various sources such as peat, bamboo, charcoal, wood, sawdust, coconut shell, olive kernels, but also from oil. It's heated in a controlled environment and in an air vacuum to obtain its characteristic porous surface. These tiny holes, or pores, can increase the area of the carbon surface from 500 to 1500 m2 / g. Due to this treatment, activated carbon can "bind" various substances that come in contact with it, in liquid and gaseous form and in quantities many times its weight. One cubic centimeter of activated carbon has the same area as an area of 50,000 square meters. Activated carbon produced from coconut shell is the most ecological and environmentally friendly!

οδηγίες βίντεο

"How do I choose the right cartridge for my water filter?"

Below the "Add to cart" button you can click on "HOW TO CHOOSE THE RIGHT FILTER". A text will appear on your screen summarizing the functions of available replacement filters for this water filter. Other replacement filters fit into your housing as well, but because there are a lot, we only recommend specific filters.

Also, just below the product description, you will see the available cartridges. If you click on the quick view "eye" you will see a summary of the specific cartridge. If you click on the image, you will be taken to the cartridge page where you can see more details. If you have not yet decided which replacement filter is right for your water filter, simply contact us! We will be happy to assist you!

"Should I install a filter on the counter or under the kitchen counter?"

This depends on your needs and the available space in your kitchen. Generally speaking, the countertop filters can be installed in seconds, but they take up space on the kitchen counter. Under-sink filters do not require space on the bench, but they need skilled hands for installation or even a plumber.

"I do not know if I need a single, double or triple filter"

If you are having problem with your water's bad taste and odour, then you need a single filter. But if you also have a lot of dirt in your water, then you need a double filter - the first stage will be a filter for reducing mud and the second one an activated carbon filter for reducing chemicals. But if you have 3 problems (eg hard water, mud and bad taste), then you need a triple filter, one for the reduction of scale, one for the mud and one for improving taste and reducing chemicals. If you use drilling water then you need a reverse osmosis filter. Whatever problem you are facing with your water, if you are not sure, just contact us! We will be glad to find the right water filter!

"How do I remember when to change my cartridge?"

Forget abou it! When it's time to change your cartridge, we'll call you or email you to remind you!

"If some part of the filter breaks, do you have spare parts?"

We have all the parts you may need for your water filer.

"What does the warranty include?"

In order for the warranty to be valid, you must maintain the filter correctly (of course it's not valid if you break it yourself and you should use the cartridges displayed in our website. If you clean your water filter internally every time you change the filters and if you change the filters at the scheduled time, your water filter should last for many, many, many years. If, however, your water filter has a problem of our own fault, (even if it was damaged during transportation) , we immediately take it back at our own expense and send a new one as soon as possible.

"I have lost the wrench and can not unscrew the device to change the cartridge"

We have all the parts you may need for your water filter, including the wrench. Feel free to contact us for assistance.

πεντακαθαρο νερακι πολυ ευχαριστημενοι ειμαστε!!
Αγγελίδης Νικος
Στην συσκευασία περιλαμβάνεται και το κλειδί αλλά και όλα τα εξαρτήματα για την σύνδεση. Αν και δεν πιάνουν πολύ τα χέρια μου κατάφερα και το πέρασα μόνος μου!!
Μένω στο Χαλάνδρι και από τότε που έβαλα την συσκευή της Watts σταμάτησα και τα εμφιαλωμένα. Το νερό δεν μυρίζει πια.
Κατσουλάρης Δημήτρης
Μετά από 5 μήνες χρήσης το νερό μου συνεχίζει να είναι πεντακάθαρο. Ευχαριστώ Primato.
Δημοσθένης Μπελεγράτης
Η αποστολή του προϊόντος ήταν ταχύτατη, μας ήρθε μόλις την επόμενη μέρα. Η εμπειρία μου με την Primato ήταν θετική στο σύνολό της, έχω μόνο καλά λόγια να πω.
Δέσποινα Αχχιλίδου
Μας βόλεψε γιατί δεν θέλαμε ούτε βρύση στον πάγκο (έπρεπε να τρυπήσουμε τον πάγκο) ούτε και φίλτρο πάγκου γιατί δεν έχουμε τόσο χώρο. Το νερό έχει πολύ καλή γεύση και μπορείτε να γεμίζετε τα γυάλινα μπουκάλια.
Μιχάλης Σαργίνης
Ο υδραυλικός χρειάστηκε ένα δεκαλεπτάκι το πολύ. Το νερό πρέπει να τρέξει λίγα λεπτά πριν το πιείτε μέχρι να "πάρει τα πάνω του". Εξαιρετική γεύση ομολογουμένως, πολύ γρήγορη παράδοση.
Γιώργος Θανασάκης
Πολύ καλή εξυπηρέτηση από το τηλέφωνο, αφιέρωσαν πολύ χρόνο για μένα και γιαυτό σας αξίζει μία θετική κριτική. Το νερό είναι πολύ γευστικό κι η παράδοση ταχύτατη.
Αλέξης Κόκκινος
Χρειάστηκα μισή ώρα κάτω από τον πάγκο κι ένα γαλλικό κλειδί για την εγκατάσταση, με βοήθησαν αρκετά τα βίντεο. Το νερό είναι όντως πολύ καλό.
Γιάννα Αλεξοπούλου
Είμαστε οικογενειακώς πολύ ευχαριστημένοι με το φίλτρο σας. Τα παιδιά μου δεν έπιναν νερό βρύσης και τώρα πίνουν. Η εξυπηρέτηση σας ήταν εξαιρετική.
