Replacement Bottle Water Filter for Tap-Fed Water Coolers

The OASIS F4 multi-element replacement filter screws into the OASIS refillable water bottle with filter and turns a bottled water cooler into a tap-fed water cooler: you fill the bottle from your own tap and the water is filtered as it flows down into the cooler. It is the only bottle filter in Greece certified with CE, RoHS and TUV NORD.

A Multi-Element Water Filter

The filter combines five different filtration materials in a single body: activated carbon, clay, ceramic elements, coral micro-balls and ion exchange resin. Each material does a different job, so the tap water reaches your cooler clean, better tasting and enriched with beneficial mineral ions.

✔ Reduces chlorine and chlorination by-products
✔ Retains sediment, rust and particles from the plumbing
✔ Noticeably improves the taste and odour of the water
✔ Enriches the water with mineral ions
✔ No electricity, no plumbing, no mains connection required

What Each Filter Element Does

Filter element	What it filters / retains	What it gives your water
Activated carbon	Chlorine and chlorination by-products, organic compounds, pesticide residues, odours	Clean, neutral taste without the smell of chlorine
Ceramic elements	Suspended particles, sediment, turbidity and micro-organisms larger than the ceramic pore size	Clear water and protection of the cooler from deposits
Ion exchange resin	Calcium and magnesium ions (hardness salts)	Softer water and less scale inside the cooler tank
Clay	Organic impurities and dissolved substances that bind to its porous structure through adsorption and ion exchange	Complements the carbon on what carbon does not capture and releases natural trace elements into the water, keeping filtration performance stable throughout the life of the filter
Coral micro-balls	They do not retain, they release: natural mineral ions	Enrichment with zinc, lithium, iodine, selenium and a balanced pH

Performance depends on the quality of the water in your area and on daily consumption.

Purchase Options: Which One Suits You

The Select filter field offers four options. The first two are single units and differ only in preparation, the other two are multi-packs with a progressive discount.

Dry filter	€25	€25	The standard price	Anyone buying a single unit and preparing it at home
Pre-rinsed filter	€28	€28	Ready to use, no 1 to 2 day wait	Anyone who wants to screw it in and use it right away
4 x filters	€80	€20	You save €20 compared with 4 single units	A household, covering roughly one year of use
7 x filters	€120	€17.14	You save €55, the lowest cost per unit	Offices, businesses and large families with high consumption

Dry or Pre-Rinsed Filter?

It is exactly the same filter. The dry one is delivered straight from the packaging and needs 1 to 2 days of soaking and rinsing before it goes in, so that the carbon dust is flushed out. With the pre-rinsed one we have done that for you: for €3 more you screw it into the bottle and use it from day one. Step by step instructions are in the Filter Preparation tab.

In the 4 and 7 unit packs the filters are supplied dry, because their service life starts from the moment they get wet. They are stored dry and each one is prepared shortly before it goes into the bottle.

How Long It Lasts and When to Replace It

The filter is replaced every 3 months, counting from the moment it gets wet and not from the purchase date. As long as it stays dry and sealed in its packaging, its service life does not start, which is why the 4 and 7 unit packs store comfortably.

Replace it earlier than three months in the following cases:

✔ When consumption is high, for example in an office or a large family
✔ When the local water is of poor quality, with a lot of scale or sediment
✔ When the filter has clogged and the water flow becomes noticeably slower

Which Coolers It Fits

The filter screws into the OASIS refillable water bottle with filter and not directly into the cooler. That means it works with any bottled water cooler, countertop or floor standing, with no modification to the appliance. If you already own the bottle, the F4 is the replacement cartridge you change every three months.

Frequently Asked Questions about the Replacement Bottle Filter

Which water coolers does the OASIS F4 filter fit?

It screws into the OASIS refillable water bottle with filter, so it works with any bottled water cooler, countertop or floor standing. No modification or plumbing connection is needed.

How often do I replace the filter?

Every 3 months from the moment it gets wet. Replace it sooner if consumption is high, if the local water is of poor quality, or if the filter has clogged and the flow has slowed down.

What is the difference between the dry and the pre-rinsed filter?

It is exactly the same filter. The dry one (€25) needs 1 to 2 days of soaking and rinsing before use. The pre-rinsed one (€28) has already been prepared by us and goes straight into the bottle.

How do I prepare the dry filter before using it?

Rinse it with cold tap water, leave it covered with water in a bowl for 1 to 2 days, then rinse it again until it stops releasing carbon dust. Screw it into the bottle, run one full fill and discard that first water. Full instructions are in the Filter Preparation tab.

What does it remove and what does it add to the water?

It reduces chlorine and chlorination by-products, pesticide residues, sediment, particles and hardness salts, while the coral micro-balls enrich the water with mineral ions such as zinc, lithium, iodine and selenium.

Is the 4 or 7 filter pack worth it?

Yes. With 4 units the price drops to €20 per filter (you save €20) and with 7 units to €17.14 per filter (you save €55). Since the service life starts only when a filter gets wet, the rest are stored dry without losing performance.

Is the filter certified?

Yes. It is the only bottle filter in Greece certified with CE, RoHS and TUV NORD.
