Frequently Asked Questions
Ecofiltro's filtration performance has been evaluated through laboratory testing. Results vary depending on the contaminant and the test conditions. For specific results, please refer to our Lab Tests page.
Ecofiltro uses a porous ceramic filtering unit. Its filtration performance depends on the type of contaminant and the conditions tested. For specific results, please refer to our published laboratory tests.
Ecofiltro Europe is intended for use with tap water only. If you have concerns about your water quality, consult a qualified laboratory or your local water authority. Filtration performance varies depending on the contaminant and the conditions tested.
Based on the laboratory results you shared, Ecofiltro has shown reductions in the following contaminants:
- Heavy metals: Lead, cadmium and mercury (100% reduction in the reported tests); arsenic (63%); and fluoride (26%).
- Glyphosate: Over 98% reduction under laboratory test conditions.
- E. coli bacteria: No coliform bacteria detected in filtered water throughout a 5,000-litre test.
- Microplastic particles: No 70 μm polystyrene particles detected after filtration in three filter units.
- PFAS: Most tested PFAS compounds fell below the laboratory’s detection limit after filtration.
- Pharmaceutical residues: 13 of 14 tested compounds were reduced below the laboratory’s quantification limit.
In laboratory testing, no 70 µm polystyrene beads were detected after filtration in tests conducted on three filter units (Measurlabs, 2025). This result applies to the specific particles and test conditions used.
Ecofiltro is not specifically designed to remove limescale or dissolved minerals such as calcium.
Yes, Ecofiltro effectively removes any bad odor or taste from the water, thanks to the activated carbon component.
Ecofiltro is designed for use with potable tap water in Europe.
It is not recommended to use the filter with hot water. The materials comprising it are not resistant to high temperatures and may reduce the lifespan of the filtering unit.
We recommend using the filter with desalinated water as the clay component enriches the water with essential mineral salts. However, we do not advise using it with seawater as it may damage the filter unit quickly.
Ecofiltro in Europe is intended for use with tap water only.
While it removes bacteria effectively, it may not eliminate viruses or other potential contaminants found in well or rainwater. If you’re considering using Ecofiltro with a non-tap water source, we recommend testing your water first and comparing the results with our published studies on Ecofiltro’s performance.

Ecofiltro operates without electricity and is designed for everyday use. The filtering unit lasts up to two years, depending on water usage and local water conditions. At the end of its useful life, it may be repurposed as a plant pot.
Ecofiltro offers an alternative to purchasing bottled water and operates without electricity. Potential savings depend on household water consumption, product lifespan, and the cost of bottled water.
The filtering unit has an expected lifespan of up to two years, depending on factors such as water consumption, temperature, and water hardness. Bacterial filtration performance has been tested up to 5,000 litres, although the time required to reach this volume varies depending on daily water usage.
We recommend performing maintenance every 6 months. If you live in an area with very hard water (high lime content), we recommend doing it every 3 months. You can also perform maintenance more frequently if needed.

Yes, it is normal. The dark coloration is a result of the activated carbon, one of the active components of Ecofiltro, which becomes concentrated during the high-temperature baking process.
Yes, at the beginning of using your Ecofiltro, you may notice a slow filtration rate. This occurs because the filter unit is new and needs time to undergo the natural process of opening the pores within its walls. The filter operates by gravity; therefore, the more you fill the unit, the more pressure the vessel will receive, accelerating the opening of the pores. With continued use, the pores will open to 100%, reaching their normal filtration.
The filtering unit has a lifespan of up to two years, depending on water usage and local water conditions. Follow the maintenance guidance provided for your Ecofiltro model and replace the filtering unit after two years, or according to the manufacturer's instructions.
Ecofiltro is made from different materials, each of which may require a different disposal method. Please follow local waste-management guidelines for the container, lid, tap and filter unit. The used filter unit may also be repurposed as a plant pot, provided it is suitable for that use.
Don't discard the used filter unit; instead, repurpose it as a pot for plants. Alternatively, break it into smaller pieces and use it as fertilizer to contribute to sustainable gardening practices.
If you choose not to repurpose the used filter unit, please ensure it is disposed of with organic waste.
For holiday periods longer than one week or during times of occasional use, we recommend keeping your Ecofiltro filled with water, both in the upper filter unit and in the lower container. This helps prevent the ceramic filter from drying out, which typically happens after about one week without use.
When you return, simply empty any standing water and refill the unit with fresh tap water as usual.
For extended absences (over 3 weeks), we also recommend performing a basic maintenance of the filtration unit. You can follow the step-by-step instructions here: Ecofiltro Maintenance Guide
In Ecofiltro, colloidal silver is incorporated into the ceramic filtering unit for its antimicrobial properties. Working alongside clay and activated carbon, it contributes to the filtration system by helping inhibit bacterial growth within the filter.
Ecofiltro has been independently tested by Measurlabs for its effectiveness in reducing PFAS and pharmaceutical residues. Laboratory results showed that most tested PFAS compounds fell below the detection limit, while 13 of 14 pharmaceutical compounds fell below the quantification limit. These results apply to the specific substances and test conditions evaluated and do not mean that all PFAS or pharmaceutical residues are completely removed.
Regarding nitrates and nitrites, we currently do not have conclusive test results confirming that Ecofiltro reduces their levels in water. We therefore do not recommend relying on Ecofiltro to remove nitrates or nitrites, particularly in areas where these contaminants are a concern.
Yes, this is normal. During the initial pore-opening process, some clay particles may settle at the bottom of the container and give the water a slight earthy taste. We recommend filling and emptying the container a few times until the taste diminishes. The discarded water can be reused for watering plants.
Ecofiltro originated in Guatemala, Central America, over 30 years ago. Since then, its use has expanded to encompass most countries in Latin America, the USA, Canada, Europe, Africa, and Asia.
Yes, it is normal behavior as clay, a natural element, brings more minerals to the water.
No, it maintains the good mineral salts but eliminates harmful substances.
Yes, we ship to Switzerland, the United Kingdom, and Andorra. Orders to Switzerland and Andorra may incur customs fees or import taxes upon arrival. Orders to the United Kingdom are shipped DDP (Delivered Duty Paid), so no customs or import fees will be charged.
Yes, we ship to the Canary Islands. Please note that customs fees or import taxes may apply.
Deliveries to the Canary Islands or outside the European Union (excluding the United Kingdom) may incur customs duties or import taxes. Such charges are not included in the purchase price and remain the sole responsibility of the recipient. Orders to the United Kingdom are shipped DDP (Delivered Duty Paid), so no customs or import fees will be charged upon arrival.
