Reverse Osmosis:

  • Produces water with zero conductivity.
  • Is ideal for areas with very hard water (eg islands) and water with high levels of arsenic or nitrates.
  • Completely removes all the harmful substances from the water.
  • Includes all parts & accessories needed for connection and installation.
  • Needs expert hands or plumbing for installation.
  • Is placed under the kitchen counter. Filtered water comes out of Primato DELUXE 101 faucet. You can select a different faucet if you want to. Price will change automatically.
  • It has a small tank where clean water is stored. This is because water is produced very slowly by reverse osmosis. So you do not have to wait at all to enjoy a glass of crystal clear water.
  • It does not have a pump. If you have low water pressure, prefer a reverse osmosis with an electrical pump.
  • It comes with a 10 year warranty!

Filtration stages:

  • 1st stage: Water passes through the polypropylene filter (PP) with a permeability of 5 microns. To give you rough idea, human hair have a diameter of 100 microns. At this stage, dirt, dirt, rust and sludge are retained. This filter protects the activated carbon block filters from clogging.
  • 2nd stage: Water is filtered by the Primato ULTRA CTO activated carbon block filter (5 microns). This filter reduces chlorine, chloroform, unpleasant taste, odor, suspended particles, sand, rust and a wide list of chemicals.
  • 3rd stage: Water is filtered by the Primato ULTRA PB activated carbon block filter (0.5 microns). This filter reduces chlorine, organic volatile compounds (VOCs), organic chemicals, unpleasant taste and odor, suspended particles, turbidity, sand, rust, heavy metals, lead and other pollutants that contaminate water.
  • 4rth stage: Water is forced to pass through the reverse osmosis membrane. The membrane has a permeability of 0.0001 microns. RO membrane can remove salts, hardness, nitrates, chromium, arsenic, poisons, germs, microbes, lead, bacteria and literally all harmful elements. The water is then stored in the tank.
  • 5th stage: Once you open the tap, the water will go through the fifth and final filtration stage. In the fifth stage we use an activated carbon filter from coconut. This filter also acts as a flavor enhancer. At this stage you can put a metal enrichment filter.

"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?"

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?"

Μένουμε Χαλκιδική, οπότε η αντίστροφη ώσμωση είναι λίγο πολύ μονόδρομος (αν μένεις εδώ μόνιμα). Το νερό είναι πολύ καλό, αν εξαιρέσεις τις πρώτες μέρες μέχρι να συνηθίσουμε τη καινούργια γεύση. Μαγειρεύουμε με το φιλτραρισμένο νερό οπότε μπορώ να πω ότι είδαμε διαφορά κι εκεί. Η εγκατάσταση είναι λίγο ζόρικη αλλά οι τεχνικοί στην πριμάτο έχουν αρκετή υπομονή από ότι φαίνεται...!

Είμαι ευχαριστημένος σε όλα τα επίπεδα με αυτή την ώσμωση και με τους τεχνικούς της εταιρίας. Το σύστημα λειτουργεί άψογα. Τα πέντε αστέρια σας αξίζουν (πέρα από την ώσμωση) για την εξυπηρέτηση και το χρόνο που σας έφαγα στα τηλέφωνα.

Όσο κι αν είδα το βίντεο, τελικά κατέληξα σε υδραυλικό. Το νερό είναι άγευστο και θέλει μερικές μέρες να το συνηθίσεις. Το νερό στην περιοχή μας δεν το πίνει κανείς γιαυτό και χρειαστήκαμε ένα τέτοιο φίλτρο. Παίρνει αρκετό χώρο στο ντουλάπι της κουζίνας. Το βρυσάκι είναι όμορφο και θέλει την πρώτη φορά δύο ώρες για να γεμίσει το βαρελάκι. Σταματήσαμε τα εμφιαλωμένα όμως και γλιτώσαμε το κουβάλημα! Θα σας προτείνω και σε άλλους στην περιοχή μας κι ευχαριστώ για το χρόνο που αφιερώσατε.

Έχουμε μεγάλο πρόβλημα με τα άλατα στην Ρόδο. Ζοριστήκαμε λίγο στην εγκατάσταση της συσκευής αλλά τα καταφέραμε. Μπράβο στους τεχνικούς που μας βοήθησαν πάρα πολύ. Το νερό δεν έχει καμία σχέση με αυτό που ήταν πριν, τώρα μπορούμε να το πίνουμε και έχει τέλεια γεύση. Συστήνεται ανεπιφύλακτα.

Κυκλοφορούν στο εμπόριο και φθηνότερες ωσμώσεις, αλλά συνήθως αυτό που πληρώνεις παίρνεις και δεν θέλαμε να έχουμε ατυχήματα γιατί έχουμε σαλοκουζίνα. Δίνουν 10 χρόνια εγγύηση, οπότε θεωρώ ότι τα αξίζει τα παραπάνω χρήματα. Το έβαλε υδραυλικός (χρειάστηκε μισή ώρα με τις τηλεφωνικές οδηγίες του Ανδρέα) και ήθελε περίπου δύο ώρες για να γεμίσει η δεξαμενή. Το αφήσαμε και λίγο να τρέξει. Το νερό είναι όντως τελείως διαφορετικό κι έχει εξαιρετική γεύση.

Αγόρασα το σύστημα για την Καλλικράτεια Χαλκιδικής που διαμένω μόνιμα. Μετά την τοποθέτηση έκανα έλεγχο του νερού και τα αποτελέσματα ήταν όπως με ενημέρωσαν από την Primato. Δεν έχω πια άλατα και φυτοφάρμακα στο νερό μου και πίνω άφοβα! Σας ευχαριστώ πολύ για τις πολύτιμες συμβουλές

Έχει πολλές ωσμώσεις στο εμπόριο, επέλεξα αυτήν λόγω της εγγύησης και κυρίως λόγω της εξυπηρέτησης. Φαίνεται ότι γνωρίζουν τη δουλειά τους. Το φίλτρο ήρθε όπως φαίνεται στις φωτογραφίες και φαίνεται ότι είναι καλή ποιότητα. Το νερό εξαιρετικό, σταματήσαμε τα εμφιαλωμένα.

Ευχαριστώ τα παιδιά στην Πριμάτο για το χρόνο που μου αφιέρωσαν (Ανδρέας + Αναστάσης). Το θέμα "αντίστροφη ώσμωση" είναι αρκετά περίπλοκο. Φωνάξαμε υδραυλικό για την εγκατάσταση για να μην κάνουμε κάτι λάθος. Το νερό βγαίνει άψογο χωρίς καμία γεύση ή άσχημη μυρωδιά.

Οι υπάλληλοι είναι φοβερά ενημερωμένοι για τα φίλτρα νερού, πήρα πληροφορίες που άλλοι δεν μου λέγανε. Το φίλτρο αυτό έχει κάνει "κατάληψη" στο ντουλαπι κάτω από τον πάγκο της κουζίνας γιατί δεν είχαμε πολύ χώρο, αλλά μπορούμε να πίνουμε επιτέλους το νερό της Χαλκιδικής που δεν πίνεται...!
