Most water filters clean the water that passes through them. But very few address a hidden problem: what happens inside the device itself over time. In a filter that runs every day, with moisture and debris, the inner chamber itself can become a hotbed of germs.

This is where Olympus's patented technology comes in. Plus: an inner chamber made of antimicrobial copper alloy that, instead of harboring germs, neutralizes them. Let's see how it works and why it matters.

The Problem That Antimicrobial Copper Solves

Every water filter is, by nature, a humid environment. Water passes through, leaving moisture, and between uses the interior remains damp. In a regular filter without antimicrobial protection, these are ideal conditions for bacteria to grow on the surfaces of the device, especially if the cartridge is left in place longer than it should be.

The result is paradoxical: a device that is supposed to give you cleaner water can, over time, add microbial load. The solution most manufacturers have chosen is to change the cartridge frequently. Center Plus with the Olympus Plus Water Filters went a step further and put the protection into the material of the device itself.

How the Copper Patent Works

Copper has antimicrobial properties that have been known for centuries. When microbes come into contact with a copper surface, the copper ions disrupt their membrane and metabolism, resulting in their neutralization. This property is recognized internationally, which is why copper is used on highly hygienic surfaces, such as doorknobs and surfaces in hospitals. The Bronze Alliance extensively documents this antimicrobial activity.

Olympus Plus Water Filters incorporate this principle into the internal filter chamber, using specific copper alloys with codes CW606N and CW508L. This is a registered patent of the Center Plus company, which transforms the filter chamber from a passive container into an active antimicrobial surface. According to the manufacturer, the chamber operates as a self-disinfecting system on a continuous basis and neutralizes up to 95% of microbes within two hours.

What does 95% mean in Two Hours?

Let's translate that into practical terms. In a regular filter, any microbes that find their way into the chamber between uses have time to multiply. In Olympus Plus Water Filters, the antimicrobial copper works continuously, even when there is no water running. Within two hours, most of the microbial load that may have accumulated on the internal surfaces is neutralized.

This does not replace regular cartridge changes, which are still necessary for performance reasons. But it does give you a second level of security: even if you delay changing them a little, the device will not become a hotbed of germs in the meantime. For a home with children or the elderly, this stability counts.

Certifications and Inspections

The antimicrobial function does not remain at the level of a claim. Olympus Plus filtration products have been tested by the Microbiology Laboratory of the University of Athens in a study of microbial neutralization, as well as by the Agricultural University for bacterial retention. The company also collaborates with the Hellenic Copper Development Institute for the documentation of the technology. In total, the filters have passed through three certified European chemical laboratories.

This foundation of testing is what separates a patented technology from a simple marketing claim. When it comes to the water your family drinks, the difference between proven and unproven matters.

Where is Antimicrobial Copper Found in Gamma?

Antimicrobial copper technology is integrated into Olympus Plus household water filters, along with ceramic materials and activated carbon that capture contaminants. The basic model Above Counter at 77 euros combines both: removes chlorine, pesticides, heavy metals, asbestos, hexavalent chromium, arsenic, lead and cadmium, while the internal copper chamber keeps the device hygienic.

If you want to see all the options, full range of Olympus Plus water filters includes Upper Bench, Lower Bench and reverse osmosis from 250 euros. If you are not sure which model suits your home, the guide to choosing the right model directs you in a few steps.

Why the Difference Matters

When comparing water filters, it's easy to get hung up on price and small pores. But antimicrobial integration is a feature that's not on paper at first glance and that the competition doesn't have. It's the difference between a filter that simply cleans the water that passes through it, and a filter that takes care of itself.

Over time, this difference translates into more consistent water quality and less stress about exactly when you need to change the cartridge. full Olympus Plus range is built around this logic: Greek construction, proven technology and protection that works constantly, not just when the water is running.

The patented antimicrobial copper is not a detail. It is the reason that Center Plus, with the manufacture of Olympus Plus Water Filters, addresses a problem that most manufacturers prefer to ignore.
