AQUACRISTAL | Replacement Water Filter Cartridge

$ 65.00

Our AQUACRISTAL glass filter cartridge is reusable: a first on the market! Return your used cartridge in its packaging. We will take care to recycle and reuse most of the parts so that we can continue to offer the filtration experience with the lowest environmental impact on the market. Fits the OVOPUR, CAVIAR and The Tower water filtration units.

Designed to reproduce the basic filtration of the natural water cycle, our reusable, multi-layer filter cartridge contains tried and tested, first-class filtering materials that have been proven to remove chemicals and organic pollutants from drinking water:

Activated Carbon – Obtained by pyrolysis and controlled oxidation to make it more porous, activated carbon has enormous power of absorption. It is used to trap pollutants that may be present in water. Our activated carbon made from recycled coconut husks can absorb up to 99% of non-polar, organic substances like mineral oils, volatile organic compounds (VOCs), aromatic polyhydrocarbons, phenols (chlorine), halogens (chloroform), and pharmaceutical residues. It is excellent for neutralizing water’s taste and smell, effectively removes yeast and micro-pollutants, and absorbs traces of certain heavy metals. Certified NSF 61

KDF 55 – A powder made up of copper alloy and ultra pure zinc, KDF 55, through a powerful oxidation-reduction process can neutralize up to 99% of chlorine, lead, mercury, nickel, chromium, and other heavy metals that may be found in drinking water. Not only can it fight the buildup of bacteria, algae, fungi, and scale, but it's 100% recyclable. Plus it contains no chemical additives and meets the exacting standards of America's Environmental Protection Agency (EPA) and Food and Drug Administration (FDA). Certified NSF 61

Quartz Crystal – Quartz is the most common mineral on earth and the third most abundant element after oxygen and silicon. Used in watchmaking and computing, it is an excellent energy amplifier and conductor. Quartz crystal sand is used to remove any lingering impurities from the water.

Microporous Bioceramics – Microporous bioceramic pellets are made using a mix of terracotta baked at temperatures of up to 1,300°C. This process creates a very porous surface (320 pores per square inch) and constant far infrared radiation. As well as absorbing chemical or organic residues that might be in the water, active bioceramics can soften and revitalize the water by reducing the size of its molecules. Far infrared radiation can reduce water's surface tension and ensure maximum hydration. It can also help stimulate blood circulation and detoxification while preventing oxidation.
