coconut shell carbonThe 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!

"Who will install my filter?"

We have our own technicians in Athens, Thessaloniki, Piraeus, and Larisa. In these areas, we offer free installation for all filters over €100; for other products, our fees are always friendly. For other regions, please contact us and we’ll find the best solution for you.
Our technicians visit your location by appointment, at a day and time that suits you. During the visit, they measure your water pressure, show you how to change the filters, provide information about the device and replacement parts, and answer any questions you may have.

If you choose to install the filter yourself: Every device comes with detailed instructions, and we have made installation videos for all our filters, available on each product page. If you need help, just call us and an experienced technician will guide you step-by-step over the phone.

"How do I choose the right replacement filter for my area?"

The replacement filters included in your package are suitable for most areas of Greece, but your device is also compatible with many other filter types. On each product page, you’ll find all available replacement filters with photos, summaries, and links for more details. If you’re not sure which filter is best for your area, simply contact us—we’ll be happy to help!

"Should I choose a countertop or under-sink filter?"

This depends on your available kitchen space and your needs. Countertop filters can be connected by yourself in seconds, but they take up space on the counter. Under-sink filters save counter space but usually require installation by a technician or plumber.

"I don’t know if I need a single, double, or triple filter."

If your problem is just taste or odor, a single filter is enough. If you also have sediment, you need a double filter—first stage for sediment, second for carbon. If you have limescale, sediment, and bad taste, a triple filter is recommended. For wells, islands, or very challenging water, we suggest a reverse osmosis filter. If you’re not sure, just contact us!

"How will I remember when to change my filter?"

Leave it to us! We’ll call you when it’s time to change your filter.

"If a part of my filter breaks, do you have spare parts?"

We stock all spare parts for every device we sell.

"What does the warranty cover?"

Under-sink filters: The warranty covers the plastic housings (provided water pressure does not exceed device limits). Faucets and metal parts are covered for 2 years; stainless steel bases for 10 years.
Countertop filters: The warranty covers plastic parts; the faucet and diverter are covered for 2 years.
Tap filters: All plastic parts are covered for 10 years; diverter for 2 years.
Shipping: If your product arrives damaged, we’ll replace it at no cost.
Warranty conditions: Please use and maintain your filter as instructed, and change cartridges on time, using cartridges from Primato or an authorized retailer.

"I lost the wrench and can’t open my device to change the filter."

We supply all spare parts, including wrenches—just let us know what you need.

"I can’t or don’t want to order online. Is there another way?"

Έψαχνα συσκευή για να σύνδεση κατευθείαν στην υπάρχουσα βρύση μου. Στο πρώτο στάδιο έβαλα φίλτρο για τα στερέα, στο δεύτερο στάδιο φίλτρο άνθρακα για το χλώριο και στο τρίτο στάδιο φίλτρο άνθρακα και για φυτοφάρμακα και βαρέα μέταλλα. Το νερό είναι θαυμάσιο. Μένω στα Ιωάννινα.

Το νερό της περιοχής μας (Δρυμός θεσσαλονικης) είναι ακατάλληλο εδω και χρονια. Με αυτη την τριπλή συσκευή, και συγκεκριμένα με το δευτερο στάδιο που αφαιρεί τα νιτρικά, και μετα από ανάλυση που κάναμε μπορουμε πλεον να πίνουμε το νερό απο το σπίτι μας. Η συνδεση είναι αρκετά απλή. Το μόνο που χρειάζεται είναι να αλλαζουμε λίγο πιο συχνα το φίλτρο για τα νιτρικά. Στο κατάστημα είχα άψογη ενήμερωση και εξυπηρέτηση.

Αρκετά μεγάλο σε όγκο, ειδικά αν έχεις λίγο χώρο κάτω από τον πάγκο της κουζίνας. Από γεύση σκίζει βέβαια οπότε κάτι χάνεις, κάτι κερδίζεις

Αγοράσαμε αυτό το φυλτρο πριν 3 χρόνια. Το χρησιμοποιώ και για πλύσιμο λαχανικών, καθώς και για συνολικά 5 άτομα. Άψογη ποιότητα νερού και μετά από 1 χρόνο λειτουργίας των φίλτρων! Καμία διαρροή, εύκολη εγκατάσταση, βολεύει και η βαλβίδα εκτόνωσης για εύκολο ξεβίδωμα! Το κατάστημα, μας ενημερώνει για την αλλαγή των φίλτρων!!

Την εγκατάσταση την έκανα μόνος μου, πολύ πιστές οι οδηγίες βίντεο. Μου πήρε ένα εικοσάλεπτο συνολικά. Στο δεύτερο στάδιο βάλαμε φίλτρο για τα άλατα γιατί εδώ το νερό είναι σχεδόν θαλασσινό...Μπορώ να πω ότι η γεύση είναι πολύ καλή. Το φίλτρο το παραλάβαμε την επόμενη μέρα
