Ecofiltro 5L - Low tech and ecological water filter

During a trip to South America, we stumbled upon the Ecofiltro at a rural market. Initially drawn to its design, we were impressed by the water filtration quality using a simple material that requires no energy and is recyclable. Originally created in Guatemala during a development mission, it is now produced by a BCorp-certified company.
We are delighted to offer it exclusively in our store today!

How does it work?

The Ecofiltro is a low-tech filter that utilizes proven-effective natural materials. It consists of several layers:

schéma explicatif de la composition du filtre écofiltro

- Clay: it creates microscopic passages that allow water molecules to pass through but not the major contaminants, bacteria, or parasites. The pores have a maximum size of 0.8 micrometers. Of course, it also blocks solid particles.

- Activated charcoal: produced by heating sawdust, activated charcoal improves the water by removing unpleasant odors, taste, and turbidity.

- Colloidal silver: A layer of silver is applied after firing as a secondary protective filter, which helps eliminate remaining contaminants. This widely used bactericide purifies water without any adverse effects.

The metal container helps protect the filter from impacts.

As water passes through this natural composite material, it sheds contaminants while preserving its mineral composition, resulting in water that is even purer than bottled mineral waters.

How effective is the filtration?

Ecofiltro vous garantit une filtration stricte des principaux contaminants : les parasites, les bactéries, les pesticides, les savons et les microplastiques (diamètre compris entre 5 millimètres et 1 micromètre).

Ecofiltro guarantees strict filtration of major contaminants: parasites, bacteria, pesticides, soaps, and microplastics (with diameters ranging from 5 millimeters to 1 micrometer).

The clay filter undergoes regular laboratory testing to ensure its effectiveness over time and to guarantee compliance with strict standards for filtration and purification. Ecofiltro was initially created for populations without access to safe drinking water, thus the safety of individuals and the potability of water are absolute priorities and scientifically validated.

In more detail, each natural component serves a specific purpose:

Clay captures:
- solids
- bacteria
- parasites
- micro-plastics

Colloidal silver eliminates:
- bacteria
- parasites
- fungi
- toxins
- viruses

Activated charcoal destroys:
- bad smells
- taste
- colour and suspended particles

Ecofiltro does not remove limestone, but it significantly reduces its content. It is important to note that limestone has bactericidal properties that help limit the proliferation of microorganisms, so it is essential to maintain a small amount in purified water.

To date, no studies have been conducted on the elimination of medications and pharmaceutical products.

⛲ An overview of colloidal silver

Colloidal silver is a natural antimicrobial that does not cause side effects or allergies.
Each clay filter is coated with 0.22 liters of colloidal silver at 530 ppm for the 5L, and 0.42 liters for the 20L, both internally and externally applied. Studies indicate that initially, there is a higher release of silver, around 40 ppb (0.04 ppm), which is well below the recommended daily intake limit of about 30 ppm. According to the USEPA (United States Environmental Protection Agency), the maximum silver intake should not exceed 5 μg per kilogram of body weight per day, which corresponds to a daily intake of 350 μg for an average adult weighing 70 kilograms.

Setting up the water filter

Caution: upon receipt, please check the condition of the filter BEFORE opening the sealed bag containing it. We cannot refund a broken filter if it has been opened.

The assembly is straightforward!

1) Insert the filter into the container, holding it firmly by the edges (not underneath) to avoid breaking it.

2) Fill the filter to the top to moisten all sides. Do not let the filter dry out after first use.

3) Close the lid and wait a few hours for the water to filter through, then enjoy clean water from the tap! Under normal operation, it produces 2L of purified water per hour.

4) Place the filter on the edge of a flat surface, ensuring the tap is easily accessible. If needed, you can place it on a wooden stand specially designed for the Ecofiltro, available HERE in our shop.

Watch how to set up the filter in this video:

During the first uses, the flow will be slower: this is normal as the pores of the clay open slowly, and the water may taste like clay. We advise you to discard the first few filtrations and taste the water until it reaches a satisfactory taste (non-clayey).

Regular maintenance of the filter

Once operational, you should clean the filter and its stainless steel container at least every 6 months.

1) Empty the water from the filter completely.
2) Carefully remove the clay filter by holding it firmly by the edges. Place it on a clean cloth.
3) With clean hands, thoroughly wash the filter using a sponge dedicated solely to this purpose. Do not use soap or detergent, only pure water. Clean the inside and outside, rinsing the sponge regularly.
4) Allow to dry on a clean cloth. Cover it with another cloth to prevent dust or insects from contaminating it.
5) Clean the metal container, lid, and tap using a brush and soap.

Here is the cleaning process in video:

Filter replacement and recycling

The clay filter has a lifespan of 2 years.
Replacement filters are available here.

For recycling the old filter, several options are available:

- You can use it as a flowerpot or for plant drainage.
- Break it into small pieces and incorporate it into soil as fertilizer.

By doing so, you contribute to ecological and sustainable gardening practices!

Otherwise, make sure to dispose of it with organic household waste.

What about energizing filtered water?

Among the very recent innovations in the field of health and well-being, hydrogenated water emerges as a very promising trend about which hundreds of scientific studies are ongoing.

In our comprehensive article on the subject of energizing, scientifically sourced, I share with you the latest discoveries on hydrogenated water, its potential benefits for our health, and the high-quality technologies that allow its production at home and on the go using a device that we have personally selected from all other devices on the market, the Mizora device, for which we have obtained a discount of €31.25 for our audience with the code BIOVIE.

So, I suggest combining both technologies, a low-tech one: the EcoFiltro, and a very innovative one, the Mizora system.

Mizora Ecofiltro dynamisation de l'eau


The journey begins with Dr. Fernando Mazariegos in Guatemala in the 1990s. He was tasked by the Inter-American Development Bank to find a simple, sustainable, and economical way to purify water for Latin American populations who lack access to this vital resource.

He closely observed indigenous populations and made it a point to use local resources and technologies. After many trials in his research center, he developed the Ecofiltro filter: "We did not invent filtration, but we have worked on the technological development applied to the use of materials and substances that enhance the process."

EcoFiltro was chosen by Corentin de Chatelperron and Caroline Pultz, with whom we are currently collaborating. Caroline and Corentin are the creators of the Desert Biosphere and have been featured by the Low Tech Lab in this video:

Due to its simplicity and low cost, it quickly gained popularity; however, the project, funded solely by donations, could not expand. Therefore, in 2000, Ecofiltro became a socially responsible non-profit organization that contributes to improving living and health conditions while fighting environmental pollution from plastic.
A few years later, in 2009, the organization transformed into a socially responsible company and expanded its production to other regions of the world. Profits generated in wealthier countries enable the provision of purified water to regions that cannot afford it.
Between 2014 and 2022, this approach allowed the distribution of 33,751 Ecofiltros to 6,210 schools.

In 2020, the company earned BCorp certification, recognizing their efforts to combat the effects of climate change and their unconditional social and environmental commitment.
*BCorp is one of the most significant labels certifying companies that aim for a benefit for all—social, environmental, and economic—in full transparency to the public.

Today, Ecofiltro is present worldwide and continues its fight for ecological, economical, plastic-free access to 100% pure filtered water.
