A few words about activated carbon

coconut shell carbon

The activated carbon in the replacement filters is an entirely natural product that looks like a fine, odorless, tasteless, and non-toxic black powder. It is produced from coconut shell, making it very eco-friendly and environmentally friendly. It is heated in a controlled environment and in a vacuum to obtain its characteristic porous surface. These tiny holes, or pores, can increase the surface area of the carbon from 500 to 1500 m2/gr. Due to this treatment, it can absorb various substances that come into contact with it, in liquid or gas form, in quantities multiple times its weight. One cubic centimeter of activated carbon has the same surface area as a 50,000 square meter surface.

"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?"

Absolutely! Just call us or visit one of our stores—we’re happy to assist you.

"I want to order online with my card, but I’m not comfortable with computers."

No problem! Call us while you’re at your computer and we’ll guide you step by step.

"How long does courier delivery take?"

Usually, delivery is the next or the following business day.

"Can I use a different filter cartridge in the future?"

Yes. If your water quality or needs change, we’ll help you choose the right cartridge.

"Will I always be able to find filters?"

Primato has operated successfully since 2008, constantly expanding our network and improving services to serve you throughout Greece.

Μεγάλη διαφορά στο νερό. Το χρησιμοποιούμε δυόμιση χρόνια τώρα.

Άριστη τηλεφωνική εξυπηρέτηση, ταχύτατη και ακριβής παράδοση (την επόμενη ημέρα στο χώρο εργασίας μου απροβλημάτιστα).
Σημαντική βελτίωση της ποιότητας νερού (δεν έχει γεύση χώματος, όπως μετά από διακοπή νερού). Το μόνο "παράπονο" είναι πως το νερό έχει λίγο τη γεύση "πλαστικού". Φταίει άραγε το πλαστικό δοχείο του φίλτρου; Η γεύση εξαφανίζεται μετά από λίγη ώρα, αν δεν το πιούμε άμεσα ή αν το βάλουμε στο ψυγείο. Το θεωρώ όμως έλασσον και γι' αυτό αξίζει τα 5 αστέρια!!!

Απάντηση Primato: Ευχαριστούμε για τα καλά σας λόγια! Σίγουρα δεν μυρίζει "πλαστικό", καθώς αυτό είναι υψηλής ποιότητας κι έχει φοβερές προδιαγραφές και πιστοποιήσεις. Σε λίγες μέρες θα συνηθίσετε τη γεύση αυτή του νερού που είναι πλέον καθαρό. Όπως και να χει, καλό είναι να αφήνετε το νερό να τρέχει για λίγα δευτερόλεπτα την πρώτη φορά που λειτουργείτε το φίλτρο κάθε μέρα προκειμένου να φύγει το στάσιμο νερό που παραμένει στο φίλτρο όσο δεν το λειτουργείτε.
