Product dimensions: 37 cm (length) x 14.5 cm (width) x 44.5 cm (height) – Tank diameter: 20 cm

Filtration Stages:

1st Stage - Solid Filter

solid filter

In the first stage, water passes through the polypropylene (PP) filter with a permeability of 5μm (1 micron = 1 thousandth of a millimeter). In this stage, soil, dirt, rust, and mud are retained.

Protects the activated carbon filters in the subsequent water filtration stages.

2nd Stage - Primato ULTRA CTO 5μm

primato ultra cto

 Improves the taste and unpleasant smell of water.

 Reduces Chlorine, rust, mud, soil, and many other harmful substances.

 Made in the USA from 100% coconut shell carbon.

 Permeability: 5μm

 Dimensions: 2.5" x 9 3/4". Fits most 10" commercial devices.

 Certified NSF 42. See certification here

 Durability: 8000L. Should be replaced once a year.

3rd Stage - Primato ULTRA PB 0.5μm

primato ultra pb

 Improves the taste and unpleasant smell of water.

 Reduces Chlorine, organic volatile compounds (VOCs), lead, heavy metals, rust, mud, soil, pesticides, herbicides, and many other harmful substances.

 Made in the USA from 100% coconut shell carbon.

 Permeability: 0.5μm

 Dimensions: 2.5" x 9 3/4". Fits most 10" commercial devices.

 Certified NSF 42. See certification here

 Durability: 8000L. Should be replaced once a year.

4th Stage - Reverse Osmosis Membrane 50GPD

osmosis membrane

The membrane has a permeability of 0.0001 microns and a production capacity of 50GPD (Gallons Per Day), which is 189 liters per day.

Reduces salts, nitrates, chromium, arsenic, poisons, microbes, and bacteria.

Has international certifications.

The water is then stored in the tank. The tank is NSF 58 and NSF 61 certified. Once you open the faucet, the water will pass through the fifth and sixth filtration stages.

5th Stage - Mineral and Trace Element Enrichment

mineral filter

In the fifth stage, water is enriched with minerals and trace elements. After enrichment, the water has ideal ratios of minerals essential for the healthy development of the human body.

Adds the following:

Cations

  • Calcium-34mg/L. Calcium is a basic element for bones and teeth. It regulates the heart and arteries and helps in the proper digestion of food.
  • Magnesium-12mg/L. Magnesium is involved in 300 different biochemical processes in the human body. It helps the immune system and proper blood circulation.
  • Sodium-22mg/L. Sodium regulates the absorption of water by our body.
  • Potassium-8.5mg/L. Acts as an electrolyte and is required to maintain the good condition of the heart, brain, kidneys, muscle tissue, and other important organ systems of our body. It works with sodium to perform some of the body's critical functions.

Anions

  • Carbonate CO32-: 10mg/l. Its presence in our body is very important as it regulates the acidic environment.
  • Sulfate SO42-: 0.3mg/l. Sulfate contributes to the absorption of nutrients, helps to deal with migraines, and removes toxins.
  • Chloride Cl-: 0.8mg/l. It is an essential electrolyte found in all body fluids responsible for maintaining acid/base balance, transmitting nerve impulses, and regulating fluid inside and outside cells.
  • Fluoride F-: 0.06mg/l. Fluoride helps prevent tooth decay.

6th Stage - Coconut Shell Activated Carbon Filter

inline carbon filter

In the sixth stage, we use a coconut shell activated carbon filter. This filter is used as a taste enhancer and provides final filtration to the water before you drink it.

Certifications:

  • The reverse osmosis membrane is certified NSF/ANSI 58 "Reverse Osmosis Drinking Water Treatment Systems" with its manufacturer's code. Look for it on NSF under the manufacturer name Easywell Water Systems, Inc.

  • The tubes are manufactured in South Korea by DMfit. They are certified NSF/ANSI/CAN 61 and are suitable for contact with water and food. Look for them on NSF under the company name DMT Co., Ltd.
  • The equipment complies with ΦΕΚ 4973/Β/2020 - "Specifications and requirements for equipment (devices or arrangements) for treating water for human consumption supplied to building internal water networks".
  • Primato maintains a complete technical file for the equipment and its consumables.
  • The final product assembly is done by our company. Primato is certified to the ΕΛΟΤ EN ISO 9001:2015 standard with a scope of "Management of manufacturing, Assembly, Marketing & Distribution of water filters".

"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.
