This is not an exhaustive list. For more details, please consult our analysis reports.

Regarding the priming of the O'Pure 2 filters, the following steps must be followed:

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

Once the filters are primed, install them in your system and perform one to two complete filtration cycles of 8 liters 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 trapped in the micropores of the filters. If necessary, you can also clean the tanks with hot water and soap before using them.

A pair of O’Pure 2 filters can filter up to 22,000 liters of water. This is a theoretical lifespan if certain conditions are met, namely that the water you are filtering is already relatively clean and that you take the time to maintain your filters according to the instructions provided in the instruction booklet that comes with the product.

On the other hand, if you are filtering water from an unreliable source, such as rainwater for example, and you do not take the time to maintain your filters, then the lifespan of these will be shorter.

Also, for optimal filtration, it is recommended to change the filters after 2 years of intensive use. Although the filters will still be able to effectively filter a good portion of contaminants even after 2 years, it is possible that their filtration power may be reduced on certain contaminants.

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

It is not unusual for the water to appear slightly cloudy or to have an unusual taste during the first use of a new filter. This is typically caused by harmless residual carbon fines (very fine particles) that can remain in the filter following manufacture and transport.

For this reason, we recommend running at least two full filtration cycles and discarding the water before regular use. Washing the upper and lower tanks with warm water and mild washing-up liquid before the first filtration can also help.

Cloudiness or taste issues may also occur if the filters have not been fully primed. In some cases, fine particles can remain trapped within the filter media during initial use. Priming the filters several times, as described in the instructions, usually resolves this and allows the filtration performance to stabilise.

In certain situations, it happens that you do not fully trust your filters. Indeed, the filtration rate may seem too fast to you 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 perform the food coloring test.
To do this, add food coloring (without sugar and without thickening agent) to the upper tank of the Earth system. It will then take on a pink or red color. Do not hesitate to mix everything so that the coloring spreads perfectly in the tank. The water that comes out of the filter must be completely clear. The best way to see this 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.

Yes, the fact that there is a little water left in the upper tank is normal and it generally concerns the last centimeters of water (between 1 to 2.5 cm). Due to the structure of the filter, water passes through very small micropores before entering the lower tank. The lower the water level in the upper tank, the less pressure there is to force the 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 exerted on the water is greater.

No, it is generally enough to clean your Weeplow® O’Pure 2 purification elements to revive them. The slow flow rate is often explained by the sediments and other residues previously filtered that clog the micropores of the purification elements. Simply remove the elements from your system and scrub the outside of each element with a stiff toothbrush or fine 3,000-grit sandpaper.
Scrub one section of the element until you see a bit of black on the pads, then move on to the next section. This simple process should only take a few minutes. Re-prime each element, then reinstall it in your unit. Your flow rate should be restored.

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

Once the filters are dry, wrap them in bubble wrap or place them in a storage bag like a resealable polyethylene 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 outside with a stiff brush. Then, prime the filters before reinstalling them in your filtration system.

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

Regarding TDS, it gives an indication of the total amount of dissolved solids in water, but in no case can you rely on this single parameter to judge the purity of your water. Indeed, TDS includes all dissolved elements in the water, whether they are undesirable elements or essential minerals for our health. Their effectiveness remains relative.

Our technology does not remove ionic minerals from the water; however, it does remove sedimentary minerals. We do not 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 reader, you are actually checking that the beneficial minerals have not been removed. The high ppm of the filtered water indicates the number of parts per million of beneficial minerals that remain in your water.

Yes, our purification elements are guaranteed for 6 months.
