Le système de filtration Neptune a été testé par plusieurs laboratoires indépendants. Il a notamment été testé en conditions réelles par un laboratoire indépendant aux États-Unis. Ces analyses ont démontré que nos filtres O’Pure 2 ont une capacité de réduction de près de 99,99% sur les bactéries telles que l’e-coli. A noter que les bactéries figurent parmi les éléments les plus difficiles à filtrer compte tenu de leur petite taille.

 Des échantillons d’eau après filtration des éléments de purification Weeplow® O’Pure 2 ont également été analysés par le laboratoire Aquatycia. Ce dernier est un des rares laboratoires agréés par le ministère de la santé française et il possède une accréditation COFRAC. A savoir que les tests ont été effectués à partir d’une eau de pluie ayant stagnée plusieurs jours. 

Vous pouvez trouverez ci-dessous les rapports d’analyse établi par ces laboratoires.

Frequently Asked Questions

What is the Weeplow® Earth filtration system? What is its use?

The Weeplow® Earth water filtration system comes with two O'Pure 2 filters. This home water purification system is the most efficient and cost-effective on the market. It uses gravity water filtration technique to effectively remove all unwanted elements contained in the water, such as pathogenic bacteria, chlorine, sediment, heavy metals, sand etc while preserving the good minerals , and all this without consuming electricity.

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 do I maintain the stainless steel tanks of my Weeplow® Earth system?

Regarding the maintenance of stainless steel chambers, we recommend cleaning the chambers with soap and hot water once a month. In areas with hard water (rich in lime), we suggest using pure vinegar or a 50-50% mixture of vinegar and water to spray and leave to act for approximately 15 minutes. Finally, wipe everything with a ScotchBrite pad or soft brush, then wash with soap and rinse. Carry out the cleaning tank by tank.

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.

How long can I keep water filtered by my Weeplow® Earth system?

We do not recommend storing water filtered with a Weeplow® product for more than 3 days. Indeed, if you keep your filtered water in a humid environment, bacteria can grow again and multiply more quickly.

Is the Weeplow® Earth filtration system guaranteed?

Yes, our Earth filtration system is guaranteed. The stainless steel chambers as well as the support and the tap with gauge are all guaranteed for 10 years. In the event of breakage, rust, leakage or malfunction, we undertake to replace or reimburse you for the item.

As for the carbon filters, they are guaranteed for 2 years.

Voulant offrir la Berkey à mon frère, je tombe par hasard sur cette Weeplow incroyable ! Je remarque qu'à qualité égale, elle dispose d'un indicateur de niveau, d'un socle inox et d'un robinet inox tout inclus et 2 fois moins chère que la Berkey ! Après recherches et comparatifs, la Weeplow s'impose à moi comme le choix évident. De plus, c'est une marque Française ! Mon frère l'a reçue en 2 jours et il est absolument ravi de son cadeau et ravi de mon choix. C'est vraiment un + ÉNORME de pouvoir voir le niveau d'eau restant dans la cuve, ce que ne permet pas la Berkey que j'ai. De plus, la Weeplow est tout aussi belle et qualitative, alors à ce prix, tout le monde peut se l'offrir. BRAVO WEEPLOW !!


Identique au système au nom plus connu et au prix plus fort...(les filtres sont identiques pour les 2 marques). Donc WEEPLOW, une belle affaire puisque en plus, il y a un petit flotteur qui indique le niveau sans avoir besoin d'ouvrir. Pour obtenir une eau propre c'est idéal. Une eau sans goût que je bois et dont je me sers pour cuisiner, pour me laver les dents..... Je recommande.


Tous les éléments sont présents, les instructions pour le nettoyage, l'amorçage des filtres et le montage complet avec mise en service sont bien spécifiés sur les emballages. Montage simple et rapide, très facile à utiliser, pas besoin d'être sorti de Saint-Cyr pour comprendre ??...c'est à la portée de tout le monde, il suffit d'avoir un peu de bon sens, de logique et d'utiliser ses 2 mains... Par précaution, même après rinçage des filtres, ne pas hésiter à vider la première eau de filtration : pour arroser les plantes, faire la vaisselle et même en guise de "chasse d'eau". L'eau obtenue est très claire et transparente comme du cristal. J'apprécie beaucoup car les éléments polluants et réellement dangereux pour la santé de l'eau des canalisations sont détaillés sur les emballages des cartouches filtrantes. Je préfère payer des cartouches filtrantes que des consultations et analyses médicales pour les maladies occasionnées par ces saletés !! Pensez à vos enfants....
