Why Biostone is Best

Why AlkaViva Biostone Filters are the Best

Lets start with WHY other ionizer filters are NOT!

  • Granulated Activated Carbon (GAC) channels water - meaning water creates distinct channels in the carbon bed. Filtration is not at all uniform and only a small part of the surface area is used reducing performance.

  • Granulated Activated Carbon is well known to not reduce a most of the scary contaminants being found in water today.

  • Some companies sell you on .01 micron filtration. They say it is used in Kidney dialysis. While it’s true, they don’t tell you that the hollow membrane fibers that allow the .01m rating ONLY reduce biological contaminants. These filters actually do a poor job at removing chlorine and chloramine, heavy metals, volatile organic chemicals etc.

  • Some companies offer test results that are woefully incomplete. While the results may look impressive they lack any protocols, such as flow rate etc that play a crucial role in performance. You could easily say smoke and mirrors.

Now, WHY BioStone?

usa made filters All our filters are proudly made to the highest quality standards, right here in our facility in Reno, Nevada USA with AlkaViva pride! Filter materials have been extensively tested for safety by independent laboratories. Our UltraWater test results show stunning reductions for 171 contaminants – it is the most thoroughly tested water ionizer filter available.

  • Carbon Block. All our BioStone filters – Basic, Plus and UltraWater - employ Carbon Block technology. Carbon Block offers more surface area and therefore more contact time than GAC, meaning more protection for you.

  • Compression Technology. Our Carbon Block is compressed, not sintered or extruded. This provides better performance, is more stable and offers longer life.

  • No Channeling. Carbon Block DOES NOT channel, meaning far superior performance.

  • No bacteria. Our BioStone is impregnated with Silver to inhibit bacterial growth – common in most carbon filters.

  • Certified Testing. We have current, complete, transparent testing done by an independent EPA / NELAC certified labs. Our testing protocols are right there in our test documents and each one is certified.


biostone basicThe BioStone Basic uses compressed carbon block technology. Its’ 3-micron rating will help reduce chloramine - a disinfectant that GAC (granular carbon) won’t touch. The Basic will out perform any GAC filter – regardless of micron rating – without channeling which saps performance. The Basic also offers you Scale Guard to protect your ionizer from hard water damage.


biostone plusThe BioStone Plus starts with the same compressed carbon block then adds "Plus Technology" by impregnating it with specialty media to increase contaminant reduction. It removes more than the Basic including chloramine, heavy metals and other tough contaminants. Containing Scale Guard protection, it will out perform any GAC filter – regardless of micron rating.


biostone alkavivaThe BioStone UltraWater uses the BioStone Plus compressed carbon block but then turbocharges it with UltraWater Wrap technology ensuring unmatched reduction. Up to 99.9% of virtually all contaminants are removed, including chloramine, pharma, heavy metals and resilient contaminants like chromium VI and arsenic. Add Scale Guard protection and it out performs any other filter we know of. Clearly the best choice you can make in a filter. Period.
