The healthy minerals remain in the water with our filtering method,

Our filters are almost all constructed from an activated carbon cylinder with a sieve perforation of 1 micron and bundle ultra membranes with a sieve perforation of 0.03 microns.

The activated carbon adsorbs all kinds of chemicals and improves the taste of the water. The 0.03 micron ultra-membranes ensure that no bacteria can pass through the filter. The water from our filter element is therefore always safe.

The natural minerals in water are always preserved with this method of filtering.

Our AQUA Logic water filters with Ultra Membranes, O3 Ozone Generators, and the new AQUA Logic UVC-LED Water Sterilizer provide an effective solution against Legionella.

Ultra Membranes: Effectively filter contaminants from the water, including bacteria (Legionella) and sediment.
O3 Ozone Generators: Eliminate harmful bacteria, including Legionella, through powerful oxidation.
UVC-LED Water Sterilizer: Neutralizes microorganisms with ultraviolet light for added protection.
Easy to install and maintain, making it ideal for worry-free water storage in your motorhome, caravan, or pleasure craft. Protect your health and invest in optimal Legionella prevention with our AQUA Logic system!

The water filters with Ultra Membranes (0.01 - 0.03 microns) are capable of removing viruses. This is because viruses often require a carrier, such as a bacterium or protozoan, to move and remain infectious. When viruses attach to these larger particles, the Ultra Membranes effectively remove them by filtering out the carrier itself.

In contrast, the ceramic filters (0.5 microns) with activated carbon and nanosilver provide a physical barrier that blocks bacteria and protozoa. However, since viruses are typically much smaller than 0.5 microns, these filters alone are not specifically designed to remove viruses. The nanosilver has an antibacterial effect and helps prevent bacterial growth within the filter but does not neutralize viruses.

For optimal protection against viruses, we recommend combining the AQUA Logic Hand Pump Filters with the Travel Mini. The Travel Mini includes an ultra-membrane filter (0.01 - 0.03 microns) that provides additional protection against viruses and other microorganisms. Check out our combo deal AQUA Logic Travel Mate + Travel Mini on the product pages for more details!

No, minerals are not filtered out of the water.

What is called lime in "hard" tap water is dissolved calcium hydrogen carbonate (and magnesium salts). When the water is boiled, the hydrogen carbonate ion decomposes into carbon dioxide, water, and a carbonate ion, reducing solubility, and the calcium carbonate precipitates or deposits on walls. In the latter case, this can be seen in the hot parts of a pan or the heating element of a kettle. This form of calcium carbonate is called scale or scale.

The purity of water cannot be measured with a so-called TDS meter because these types of meters also measure the healthy minerals in the water.

Unfortunately, the misunderstanding that TDS meters can be used is something that we, and other manufacturers of water filters, are regularly confronted with.

This is mainly because producers of so-called 'reverse osmosis systems' claim that this is the way to test their water. Water extracted from an RO system is completely stripped of natural minerals. In our opinion, drinking this type of water is not recommended because it can extract healthy minerals from your body.

With our filters, healthy minerals (for example lime/calcium) are not filtered out of the water. In fact, the use of activated carbon will even increase the number of particles measured with a TDS meter, compared to unfiltered water.

Due to the very small sieve perforation of 0.03 microns, the bundle of ultra membranes that are inside most filter elements do not allow bacteria to pass through.
Both ditch water and rainwater can therefore be purified with these types of elements.

However, depending on how dirty the water is, the filter will close at some point. When you have the choice of water source, the advice would be to use rainwater because it is much purer than surface water such as ditch water.
The filter will then last longer.

Iron (FeII) is often a problem in shallow groundwater and sometimes also in surface water. Iron in itself is not very toxic to crops and animals, but iron-containing water can cause various technical problems such as clogging of water filters and pipes and the associated problems with machines. In addition, too high an iron content can cause rust deposits on crops or give an unpleasant odor and taste to the water.

In order to filter iron, it is necessary to oxidize it first with air (oxygen) or ozone:

Through aeration. Aerating water can be done in several ways:
a. Using a large basin in which the water is atomised. Due to this atomization, the water comes into contact with a lot of oxygen and the iron can be converted to the settleable form.
b. Applying an Ozon generator by which ozone is pumped into a tank or vessel containing the ferrous water.

After iron has been oxidized (from FeII to FeIII), it can also be filtered out of the water with our pre-filters.

Yes, AQUA Logic Water Filters equipped with activated carbon efficiently reduce lead levels in your water supply. Activated carbon is known for its ability to adsorb various impurities, including heavy metals like lead, effectively improving the overall quality and safety of your drinking water. Regularly replacing the filter cartridges as recommended will help maintain optimal performance in removing contaminants, providing peace of mind and reassurance in your water filtration system.

No, our water filters do not filter fluoride from the water because fluoride is a substance dissolved in the water. In the Netherlands and most other EU countries, fluoride isn't added to drinking water.

Yes, AQUA Logic water filters do remove synthetic hormones from the water. Synthetic hormones that can be present in our tap water are primarily derived from human use and wastewater discharge. Here are some examples of common synthetic hormones that can contaminate our tap water:

Ethinylestradiol: This is a synthetic variant of the female hormone estrogen and is often used in birth control pills.
Norethindrone: This is a synthetic progestin hormone used in birth control pills and hormone replacement therapy.
Tamoxifen: A hormone therapy medication used in the treatment of breast cancer, which can enter the water through medication disposal.
Bisphenol A (BPA): While not a hormone in itself, BPA is considered an endocrine disruptor. It is commonly used in plastic production and can leach into the water from plastic bottles and containers.
Perchlorate: Not a hormone but a substance that can affect thyroid function by inhibiting iodine uptake. It's often found in fertilizers and can enter the water.
Triclosan: An antimicrobial agent frequently used in personal care products like soaps and toothpaste. It can enter the water through disposal.
These synthetic hormones can enter the environment when people consume and excrete them, and when medications and personal care products are flushed into the sewage system. Water treatment plants might not always be able to completely remove all of these substances from the water, leaving them present in our tap water.

An AQUA Logic water filter can effectively remove these synthetic hormones from the water using activated carbon filtration:

Activated Carbon Filtration: Activated carbon, also known as activated charcoal, is a porous material with a large surface area that exhibits a strong affinity for organic molecules. Here's how activated carbon filtration works to remove synthetic hormones:

Adsorption: Activated carbon has microscopic pores and a large internal surface area. As water flows through an activated carbon filter, synthetic hormones and other organic pollutants are attracted to the surface of the carbon particles. This process is known as adsorption, where contaminants adhere to the carbon surfaces.
Chemical Attraction: Activated carbon's high affinity for organic molecules is due to the chemical attraction between the carbon atoms in the material and the contaminants in the water. This effectively removes synthetic hormones from the water, trapping them within the pores of the activated carbon.
It's important to note that the performance of activated carbon filters may diminish over time as the pores become saturated with captured pollutants. Regular maintenance and replacement of the activated carbon are necessary to maintain filter efficiency.

Yes, our water filters reduce PFAS in the water.

Activated carbon and ultrafiltration membranes with pore sizes in the range of 0.01 to 0.03 microns can effectively remove certain PFAS (per- and polyfluoroalkyl substances) from water, but their efficiency can vary depending on the specific PFAS compounds and the water conditions. PFAS are a group of synthetic chemicals that have been widely used in various industrial and consumer products, and they are known for their persistence in the environment.

Here's how activated carbon and ultrafiltration membranes work in the context of PFAS removal:

Activated Carbon:

Activated carbon is an excellent adsorbent for many organic compounds, including some PFAS. It can effectively adsorb certain PFAS from water due to its high surface area and porous structure.
The efficiency of activated carbon in removing PFAS depends on factors such as the type of activated carbon used, the contact time between water and carbon, and the pH of the water. Some PFAS compounds are more readily adsorbed than others.
Activated carbon is particularly effective in removing longer-chain PFAS compounds, but it may be less efficient in removing shorter-chain PFAS.

Ultrafiltration Membranes:

Ultrafiltration membranes with pore sizes in the range of 0.01 to 0.03 microns can physically block the passage of particles and some large molecules, including some PFAS.
The effectiveness of ultrafiltration membranes in removing PFAS depends on the molecular size and charge of the PFAS compounds. Some PFAS may be effectively removed, while others with smaller molecular sizes might pass through the membrane.

It's important to note that while activated carbon and ultrafiltration membranes can be effective in reducing PFAS levels in water, they are not always 100% efficient at removing all PFAS compounds. Additionally, the effectiveness of these methods can be influenced by the specific PFAS mixture in the water, the concentration of PFAS, and other water quality parameters.

Activated carbon, also known as activated charcoal, is an effective adsorbent that can remove various contaminants from water. Here is a list of some common substances that activated carbon can adsorb from water:

Organic pollutants: Activated carbon can adsorb a wide range of organic compounds, including volatile organic compounds (VOCs), pesticides, herbicides, solvents, industrial chemicals, phenols, and chlorinated compounds.

Odor and taste compounds: Activated carbon can adsorb unwanted odors and tastes in water, such as those caused by organic compounds, chlorine, or biological degradation byproducts.

Chloramines: Activated carbon can adsorb chloramines, which are chlorine compounds often used as disinfectants in drinking water treatment. Removing chloramines contributes to improving the taste and odor of water.

Chlorides: Activated carbon can adsorb chloride ions, although the capacity to adsorb chloride may be limited depending on the type of activated carbon and the concentration of chloride in the water.

Heavy metals: Activated carbon can adsorb certain heavy metals, such as lead, mercury, cadmium, copper, and zinc. However, the adsorption capacity varies depending on the specific metal and conditions.

Pharmaceuticals and hormones: Activated carbon can adsorb pharmaceutical residues and hormones that may be present in water due to wastewater discharges and other uses.

Our ultrafiltration membranes with a pore size of 0.01 to 0.03 micrometer/micron (µm), also referred to as 10 to 20 nanometers (nm), can effectively filter a wide range of contaminants from water, including:

Bacterial reduction: Our ultrafiltration membranes of 0.01-0.03 µm can provide exceptional bacterial reduction, with an efficiency of 99.9999% (≥99.9999%) or higher. This means that more than 99.9999% of bacteria, such as E. coli, Salmonella, and Legionella, are effectively removed from the water.

Suspensions and particles: These membranes are capable of filtering various suspensions and particles from the water, including sediment, sand, clay, rust particles, and other larger contaminants. The pore size of 0.01-0.03 µm ensures that these particles are retained while allowing purified water to pass through.

Algae and microorganisms: Ultrafiltration membranes are effective in removing algae, protozoa, and other microorganisms from the water. These membranes can help reduce turbidity and improve the clarity of the treated water.

Viruses: Although some viruses are smaller than 0.01-0.03 µm, they can still be partially removed through the ultrafiltration process. This is because viruses are often associated with particles or aggregates that are larger than the membrane pore size.

Macromolecules: Ultrafiltration membranes can remove macromolecules, such as proteins, polysaccharides, and some organic compounds, from the water. This helps reduce organic contaminants and improve water quality.

Although many manufacturers claim that their filter can purify a certain amount of water, this is often difficult to verify and measure.

The amount of water that can be filtered is strongly dependent on the degree of pollution of the water. Then there is also the question of what you filter and test the water on. Only bacterial reduction or also other potentially harmful substances?

The Travel-Mate has been tested for bacterial reduction; with at least 6000 liters of water, no reduced effect is visible.

With this filter we supply a sandpaper with which the ceramic can be sanded clean every now and then. If this becomes too thin (measure with the supplied jig) the filter needs to be replaced.

The lifespan of a water filter like the AQUA Logic Siphon CS-Ultra depends on the quality of the water being filtered. The filter contains ultra-membranes that effectively block bacteria. Over time, these membranes can become clogged with particles such as mud or other visible contaminants. A noticeable decrease or complete stop in water flow is a clear sign that the filter needs to be replaced.

The filter also contains activated carbon, which adsorbs odors, discoloration, and chemical substances from the water. This function gradually diminishes. How quickly this happens depends on the type and level of contamination in the water. For this reason, we recommend replacing the filter element after one year of use, even if water is still flowing through.

In practice, Siphon filters often provide clean drinking water to families in developing regions for 1 to 2 years with daily use. The actual lifespan varies depending on water quality and how intensively the filter is used.

As long as the filter is used correctly according to the manual and water continues to flow through, the filtered water is safe to drink.

When the water filter has already been put into use and will not be used for a while, it is important to prevent bacterial growth in the filter element by removing it from the filter housing and storing it in one of the following ways:

We recommend adding Cosil47 water filter disinfection solution. Rinse the filter before using it again.

Wet: store the filter element (for example in a plastic bag) in the refrigerator.

Dry: find a suitable place to let the filter element dry without mold formation. Prevent the plastic caps from getting heated by for example a heater/radiator.

For extra Bacteria reduction, the Filter elements consisting of Ceramic or activated carbon but without Ultra membranes are treated with Nano-Silver. With the C-Ultra filters, this is not immediately necessary due to the extra high filtration of the ultra-membranes, because in principle the ultra-membranes do not allow bacteria to pass through. However, if desired, it is also possible to give the activated carbon blocks of these filter elements a Nano Silver treatment. This inhibits possible bacterial growth in the activated carbon and can therefore extend the life of the filter. These filters are then referred to as CS-Ultra.

Colloidal silver consists of pure water in which nano silver particles are dissolved. A colloid is a molecular particle (in this case silver) with a size of 1 nanometer or smaller.

Because the particles are so small, they can be dissolved in water (suspension) in a special process. In that case, these particles remain in solution and will not separate (sediment).

Because silver colloids are so small, they have a strong (positive) ionic charge. This positive charge always looks for a negative discharge.

When colloidal silver comes into contact with (pathogenic) micro-organisms, the positively charged silver colloids will bind to the negatively charged enzymes from these micro-organisms. As a result, these (aerobic) organisms can no longer produce oxygen and thus die without being able to multiply.

Yes, all of our Water Filter Models and Filter Elements are BPA and BPS-Free.

Iron removal from water is an essential process to eliminate unwanted iron particles. An effective method that is gaining popularity involves the use of an ozone generator. In this article, we will explore the principles behind using an ozone generator for iron removal from water and discuss its application.

The Principle of Iron Removal with an Ozone Generator:

An ozone generator produces ozone (O3), a powerful oxidizing agent, through electrical discharge or ultraviolet (UV) light source. This ozone is then injected into the water. The oxidation process of ozone converts dissolved iron (Fe2+) into iron particles (Fe3+). These particles can subsequently precipitate and be removed from the water.

Application of an Ozone Generator for Iron Removal from Water:

Ozone Injection: The ozone generator is placed near the water reservoir, and ozone is injected into the water using diffusers. The ozone mixes with the water and initiates the oxidation process of the dissolved iron.

Oxidation Reaction: Ozone reacts with the dissolved iron, oxidizing it from Fe2+ to Fe3+. This reaction causes the iron to leave its dissolved form and convert into a solid state.

Precipitation and Removal: The oxidized iron particles settle and form sediment at the bottom of the water reservoir. This sediment can then be removed using sediment filters, sedimentation, or other appropriate methods.

Benefits of Using an Ozone Generator:

Efficiency: An ozone generator can effectively remove iron from water, even at low concentrations.

No Chemical Residuals: Unlike some chemical iron removal methods, the use of an ozone generator leaves no unwanted residuals in the water.

Safety: Ozone is a powerful oxidizing agent, but it quickly breaks down into oxygen without harmful side effects.

Wide Range of Applications: An ozone generator can be used for iron removal in both drinking water and process water in various industries.

Conclusion:

The use of an ozone generator offers an efficient and environmentally friendly method for iron removal from water. Through the oxidation process of ozone, dissolved iron particles are oxidized and converted into precipitate, which can be removed. With its efficiency, safety, and versatility, an ozone generator has become a valuable tool in iron removal technology, contributing to the production of clean water for diverse purposes.

Yes, an ozone generator can be used effectively for legionella prevention. Ozone is a powerful disinfectant that can kill bacteria, including Legionella. The ozone process oxidizes and destroys the cell walls of microorganisms, rendering them harmless.

When using an ozone generator in combination with other appropriate measures, such as water filtration, you can set up a powerful system to prevent the growth of Legionella and other harmful bacteria in your water storage.

The AQUA Logic - O3 - Micro Ozone Generator produces a minimal amount of ozone gas, making it completely harmless with good ventilation of the clean water tank. Ozone gas returns to oxygen after about 25 minutes, and with adequate ventilation there is no risk of ozone gas buildup. The limited amount of ozone gas dissolves quickly in the ambient air, making it safe for use.

There is no difference in the filter element: both sets contain the AQUA Logic - Gravity - CS-Ultra water filter element. With this filter element, even surface water can be made into safe drinking water.

The difference lies in the water reservoirs and some additional options:

The Gravity Blue is a consumer product with a more beautiful and high-quality water reservoir. In addition, this model contains two holes (with 1 closing cap), so that a second filter element can be used simultaneously if desired. This makes it possible to filter a larger amount of water per day more quickly.

The Gravity Buckets are the budget version, composed of food grade buckets that we have modified ourselves. These sets are often used in our emergency aid projects in collaboration with the IBOTA.org Foundation.

Both water reservoirs are made of food-grade material and are BPA/BPS free.
