The Earth filtration systemhas been tested by severalindependent laboratories. In particular, he wastested in real conditionsby an independent laboratoryin the USA. These analyzes have demonstrated that our O'Pure 2 filters have aalmost 99.99% reduction capacity on bacteria such as e-coli. Note that bacteria are among the most difficult elements to filter given their small size.

Water samples after filtrationWeeplow® O'Pure 2 purification elementswere also analyzed by the laboratoryAquatycia. The latter is one of the rare laboratories approved by the French Ministry of Health and it hasCOFRAC accreditation. Please note that the tests were carried out using rainwater that had stagnated for several days.

Frequently Asked Questions

What is the list of unwanted elements eliminated by Weeplow® O'Pure 2 filters?

The following elements are eliminated by more than 99% by Weeplow® O'Pure 2 filters:

  • Coliforms
  • E-Coli
  • Lead
  • Iron
  • Mercury
  • Chlorine
  • Bisphenol A
  • Chloramines
  • Pharmaceutical products
  • Petroleum contaminants
  • Methylcyclohexane-methane
  • Pesticides
  • Heavy metals
How do I prime my Weeplow® O'Pure 2 filters before first use?

Regarding priming the filters, the following steps must be followed:

  1. Place the small beige gasket provided on the filter thread to ensure that the water penetrates the filters and does not splash everywhere
  2. Then place the seal against the faucet
  3. Slowly open the tap so that cold water enters through the filter
  4. Hold the position for at least 2 minutes, you will then see the filter oozing water.

Once the filters are primed, install them into your system andcarry out 1 to 2 complete filtration cycles of 8L before consuming the water. Indeed, it sometimes happens that the water is cloudy during the first filtration cycles. This is generally due to residual dust stuck in the micropores of the filters. If necessary, you can also clean the tanks with hot water and soap before using them.

How long does a Weeplow® O'Pure 2 filter last? How often should our filters be replaced?

The Weeplow® O'Pure 2 filter is designed to purify approximately 11,000 liters of water before needing to be replaced. Two filters can thus purify around 22,000 liters of water. If you have a two-filter Weeplow® Earth system and you filter 10 liters of water per day, then the filters will last approximately 2,200 days, or just over 5 years. The exact lifespan depends on the quality of the water you are filtering. In this case, this calculation concerns normal tap water without too much limescale. If you filter water from an unknown source such as a pond or river, depending on the water quality, the lifespan of the filters may be halved.

How to maintain Weeplow® O'Pure 2 filters?

For the filters, our recommendations are to wash them every 2 months in cold water (always) and rub them lightly using fine sandpaper or a toothbrush. Scrub a section of the filter until you see some black residue on the pads, then move on to the next section. Finally, reprime each filter, then reinstall it in your tank.

Why is my filtered water cloudy and tastes bad?

Sometimes the water may be cloudy the first time you use it. This is generally due to residual dust accumulated in the filters during their manufacturing and transportation. This is why we recommend carrying out at least 1 complete filtration cycle before starting to consume the water. You can also clean the tanks with hot water and soap before attempting a new filtration cycle.
Poor priming of the filters can also be the cause of this cloudy water. Indeed, dust may initially be lodged in the filter. Please prime your filters several times if necessary.

Why and how to perform a food coloring test?

In some situations, you may not have complete confidence in your filters. Indeed, the filtration rate may seem too fast or the filtered water may have a slight taste at the outlet.
In order to isolate the problem as best as possible it is often useful to carry out a food coloring test.
To do this, add food coloring (without sugar and without thickening agents) to the upper reservoir of the Earth system. This will then take on a pink or red color. Do not hesitate to mix everything so that the dye spreads perfectly in the tank. The water coming out of the filter should be completely clear. The best way to see it is to put a little water in a glass. You will then be able to judge at a glance whether the filtration system is working optimally.

Some of the water in the upper tank of my Weeplow® Earth system is not flowing through the filters. Is this normal?

Yes, the fact that there is a little water remaining in the upper tank is normal and this generally concerns the last few centimeters of water (between 1 and 2.5 cm). Due to the structure of the filter, the water passes through very small micropores, before entering the lower reservoir. The lower the water level in the upper reservoir, the less pressure there is forcing water through these micropores. You may have noticed that the system purifies much faster when the tank is full than when it is half full. This is because the pressure on the water is greater.

I have been using my purification system for several months and the filtration speed has decreased considerably. Do I need to replace the items yet?

No, it is generally enough to clean your Weeplow® O'Pure 2 purification elements to bring them back to life. The slow flow rate is often explained by sediments and other previously filtered residues which clog the micropores of the purification elements. Simply remove the items from your system and scrub the exterior of each item with a stiff toothbrush or 3000-grit fine sandpaper.
Rub a section of the element until you see a little black on the pads, then move on to the next section. This simple process should only take a few minutes. Reboot each item, then reinstall it in your unit. Your flow should be restored.

I'm going on vacation, what should I do with my O'Pure 2 purification elements? How to store them?

If you do not plan to use your filters for more than 5 days, we recommend that you remove them from your filtration system and allow them to dry for at least 3 days.

Once the filters are dry, wrap them in bubble wrap or put them in a storage bag such as a resealable polythene bag. Finally, store them in a dry place, away from direct sunlight.

When you are ready to reuse your filters, clean them by scrubbing the exterior with a stiff brush. Then, reprime the filters before reinstalling them in your filtration system.

The shelf life of Weeplow O'Pure 2 purification elements is unlimited.

Why does TDS remain high after filtration?

Regarding the TDS, it gives an indication of the total amount of solids dissolved in the water but in no case can you rely on this simple parameter to judge the purity of your water. In fact, TDS takes up all the elements dissolved in water, whether they are unwanted elements or minerals essential to our health. Their effectiveness remains relative.

Our technology does not remove ionic minerals from water, but it does remove sedimentary minerals. We do not, however, include solutions that would remove beneficial minerals such as calcium or magnesium, these minerals pass directly through the elements. When you test the water, after filtering it, with your TDS meter, you are actually checking that the beneficial minerals have not been removed. The high ppm filtered water indicates the number of parts per million of beneficial minerals that remain in your water.

Are O'Pure 2 water filters guaranteed?

Yes, our purification elements are guaranteed for 6 months.

C'est la troisième que j'achète et pour cause j'en suis totalement satisfaite (déjà pour moi, puis ma maman et là mon papa). Nous avons des soucis d'eau dite potable. Pour vous montrer l'efficacité, je vous laisse voir l'état des filtres là deux mois, depuis je les nettoies tous les mois ! Et nous sommes en haute montagne 1400 m ... La source est passable en bactériologie je m'étonnais de faire à répétition des colites bactériennes je m'étonne plus et je n'en ai plus fait depuis ! C'est donc pour ma part une totale réussite, je ne pensais pas boire autant de saleté ... avant le filtreur ! Pour ceux qui ont du mal avec la notice ou l'amorçage : tuto youtube c'est simple et clair autant que pour l'entretien d'ailleurs !


J'avais acheté ces filtres Weeplow il y a 1 an et demi alors que je ne connaissais rien de cette marque. Avec du recul je peux maintenant affirmer que c'était un très bon choix. Je viens de racheter une paire de filtres pour passer à 4 filtres pour filtrer l'eau de mon forage, mes deux anciennes cartouches étant encore comme neufs je vais normalement doubler ma vitesse de filtration. En plus je viens de voir que le vendeur garantie les filtres pendant 2 ans, c'est gage de qualité, une marque de confiance que je recommande


J’ai panaché 2 filtres céramique avec 2 filtre noir. Bonne filtration de l'eau

Wolf L.P.

Livraison rapide, soignée. Excellent produit de filtration

Mr. B.

Mes cartouches d’origine British Berkefeld faisaient du gouttes par gouttes. Ici on a une purification bien plus rapide. Aucun moyen de mesurer l'éventuelle incidence d'une filtration plus rapide sur la qualité obtenue. 4 étoiles au lieu de 5 car point de joint inclus et donc pas d'amorçage. Il n'y avait pas d'amorce à faire avec mes précédentes cartouches d'origine en céramique. Effort de communication nécessaire pour préciser cette histoire d'amorce et surtout, l'harmoniser entre le descriptif Amazon, le site internet du fabricant et la notice sur la boite, parfois contradictoires,. SAV réactif qui a résolu mon soucis très rapidement et de manière très professionnelle. Mais besoin urgent de renforcer les contrôles qualité avant expédition notamment à cause de trop nombreux joints d'amorçage manquant, ainsi qu'un besoin urgent de communication à améliorer pour l'amorçage comme précédemment cité. Cela désengorgera le SAV. PS: pour info, j'ai photographié le joints d'amorçage qui doit être inclus avec les cartouches. À vérifier directement à réception de votre colis sinon SAV directement.


Bjr, Ces filtres s’adaptent très bien sur le Purificateur d'eau British Berkefeld de 6litres. Il reste 1 cm entre le couvercle du haut et les filtres. Niveau filtration c'est rapide par rapport a mes anciens filtres céramiques ! Pour le goût, ces filtres font le job, pas de goûts de javel ou odeurs quelconques ... Pour moi l'achat est valide, a voir dans le temps.


J'ai acheté ces filtres pour remplacer les berkey qui sont arrivés en fin de vie. Ces filtres sont testés par un Labo français accrédité Cofrac, je me suis donc laissé tenté. Au final je suis satisfaite des filtres et les joints sont de très bonnes qualités ! La notice d'installation au dos du packaging est en français et ils s'adaptent parfaitement à ma cuve Big Berkey.
