As their name implies, gravity fed filters use the power of gravity to pull water through various filter medium, namely Activated Carbon, which is excellent for reducing a narrow range of contaminants as well as oxidizing disinfectants - this includes most everything from natural organics, to chlorine to THM's to pesticides and herbicides, etc...there are hundreds of them, which sounds impressive. However, since these impurities accumulate in the carbon (quite unpredictably) the consumer has to be VERY careful to frequently change cartridges. Furthermore, Activated Carbon alone cannot remove (adsorb) dissolved inorganics (ions), toxic metals (most forms), fluoride, radionuclides as well as many pharmaceuticals and personal care products.

It’s worth noting that the most popular gravity fed filters on the market today do not meet NSF/ANSI purification standards. The NSF/ANSI protocol is the gold standard in water tests, while the three recognized third party testing organizations in North America are IAPMO, Water Quality Association and NSF International. Interestingly enough, there are no gravity fed filters with accreditations from these testing parties, unlike AquaTru. Lesser reputable testing facilities have tried to spin their testing results to say they meet the NSF/ANSI standard, however did not reproduce the entire protocol, namely meeting the minimum # of gallons to be filtered. There have been multiple lawsuits made against one of the more popular gravity fed filters regarding their certification tests. It is so serious that the FDA has placed stop orders and the company is banned in multiple states.

PACKAGING, plain and simple. Quinton is packaged in glass ampoules, while Quintessential is packaged in travel-friendly sachet’s. Quinton Hypertonic is the same exact solution as Quintessential 3.3, while the Quinton Isotonic is the same solution as Quintessential .9.

Quinton Marine Plasma in glass ampoules is a pharmacologically certified sterile and apyrogenic solution The QUINTON PLASMA that goes into the sachets starts out qualifying as "Sterile & Apyrogenic" but this cannot be guaranteed over time because of the nature of the sachet packaging.

Glass is a very good container for marine plasma, and the stability is longer than sachets. The biggest difference between sachets and ampoules is the organoleptic test. After 3 years the taste of the product can change, a little but not too much, due to packaging material in sachets. In ampoules this does not occur. For glass ampoules the shelf life is 5 years; for sachets, shelf live is 3 years.

Quinton Hypertonic (QuintEssential 3.3) is The NUTRIENT: Raw, unadulterated seawater

Hypertonic and Quintessential 3.3 is Nature’s original electrolyte boost, hydrating with a synergy of trace minerals and elements that provide far superior health benefits than salt, sugar, and food coloring. Replenishing your bioterrain, Quinton hypertonic solution creates a foundation of properly functioning systems that help maintain your overall health for the long-haul. Take to remineralize RO water, immediate revitalization and during times of vigorous activity and sweating.

Quinton Isotonic (QuintEssential .9) is the TONIC: Raw seawater, diluted with spring water to match the concentration of human plasma.

At a 0.9 concentration, it mimics your own blood plasma, making Isotonic ideal for daily maintenance, detoxification, replenishing trace nutrients, and when feeling under the weather.

Quinton Marine Plasma has been harvested from plankton blooms and processed as a medicine since 1897. The facility in Alicante, Spain is an ultra-advanced pharmaceutical environment with world class standards. All of the marine plasma that comes from Laboratoires Quinton meets the most stringent Injectable, IV, Sterile, Apyrogenic medical standards.

More than 100 control parameters guarantee the maximum quality and safety of Quinton. Throughout the production and packaging process, raw materials are subjected to physical, physiochemical and biological analysis, altogether testing more than 100 parameters which guarantee that Quinton's Plasma and its by-products are of the highest quality and safety for consumption and remedial use.

All batches of raw material seawater are subject to rigorous controls. Quinton undergoes dual pass 0.2 micron Sterilization Filtration (no heating or application of energy is ever used). For a frame of reference, a hair is 80 microns, and plastic microparticle studies show that the predominance of microparticles fall into the range of 344 to 686 microns.

Quinton undergoes this double cold microfiltration in a sterile environment to eliminate the content of microorganisms. These procedures guarantee seawater which is suitable for consumption (or IV use in other parts of the world). This process allows preservation of seawater's natural qualities and organic matter content, preventing the emergence of free radicals and avoiding the micro-precipitation of some minerals such as calcium and magnesium salts. This is common when other treatments such as heat or ultraviolet are used, which are responsible for the irritating or dehydrating effects of other seawater-based products.

In the laboratory, Quinton implements the protocols and recommendations of organizations such as the EFSA (European Food Safety Authority) and the AECOSAN (Spanish Agency for Food Safety and Nutrition), in addition to other in-house controls, thus ensuring the absence of contaminants such as heavy metals, oil derivatives, pesticides, radioactivity, microplastics and pathogens. Quinton's pharmaceutical production unit complies with the ISO 9001, ISO 14001, FDA's Food Supplements GMPs, GMPs and GMP/NCF Cosmetics (ISO 22716) standards.

To date, plastic microparticles have NOT been observed in raw Quinton seawater by the in-house Quality Control laboratory during the microscopic examination step (used to identify plankton and microbial species). Nor have plastic microparticles been reported by the independent Third-Party laboratory, ALKEMI (Laboratorio de Analisis y Consultoria).

Quinton is the gold standard - they have studied and perfected the harvesting and manufacturing of sea plasma, and this is why Quinton has been used and trusted for over 120 years.
