Replacing the Filters in Your Ecowater RO System
If you own an Ecowater unit, you've probably noticed that the brand doesn't sell filters. The filters compatible with its units are specific bayonet filters, the only ones on the market, so customers who need new filters have to go through a company that charges them 290 € per year to maintain their RO system.
This is the captive-market principle, and we firmly oppose the idea of holding our customers hostage by selling them a product that then forces them to subscribe to another product. Of course, we also sell our products and the corresponding filter cartridges, but at Josmose.fr, we prefer to become a trusted partner to our customers instead of tying them down. That's why the vast majority of our RO systems come with standard filters you can find anywhere, except for the Ultimos, for which standard filters were not suitable.
Being locked into paid maintenance
Your home Ecowater RO system needs regular maintenance, and naturally, you're looking to replace the filters, pre-filters, or membranes. Look no further! We regularly receive calls from people who have bought an RO system from this brand and are desperately wondering where to find its filters and pre-filters. The only solution that seems to be available on the market today is to go through the brand with a 290 € annual subscription to have a professional come to your home to replace the filters… That's how you get trapped!
A possible alternative : josmose.fr
You feel trapped, and rightly so! This business practice of keeping customers captive seemed destined to continue until the arrival of the internet. Now, consumers can search for the information and products they need themselves, compare offers in terms of both technical specifications and pricing, and then make an informed choice. This is true in the water industry, but also in the automotive, telecommunications, and high-tech industries, or any other field where the internet helps consumers become better informed and make thoughtful decisions.
Josmose respects its customers and builds trust

At josmose.fr, we've adopted a completely different policy.
First, you buy your RO system at a fair price.
Next, an RO system ordered from josmose.fr includes the pre-filters and reverse osmosis membrane it needs to operate. That seems like the bare minimum to us!
We also offer pre-filter replacement kits or 2-year, 4-year, or 6-year maintenance kits at very favorable prices, helping you save a substantial amount.
A 2-year maintenance kit for the 75 GPD Classicos RO system costs 89 € incl. VAT : a far cry from the 290 € per year Ecowater charges! You may point out that this company sends a technician to replace the filters. Of course, that person needs to be paid, and their mileage, travel time, and work time need to be factored in. But do you really need someone to come to your home to replace the pre-filters?
At Josmose.fr, we prefer to offer you a more economical solution that isn't necessarily more complicated : a simple instructional video is enough to explain the procedure! And you'll have two reasons to feel good about yourself: you did it on your own, and you saved money!
After all, when you think about it, what do you need to do? Simply shut off the faucet, drain any water left in the RO system, open the unit with the wrench supplied with the pre-filters, and replace them. Then close it back up, and there you go! You're done! Our RO systems also have labels that let you keep track of when you replace these pre-filters and consumables.
So the dilemma you thought you faced is no longer a dilemma! Will you keep paying 290 € per year for a technician to visit, or will you invest in a unit from another brand that will save you money every year? Your only obligation is to replace the pre-filters and reverse osmosis membrane yourself: about twenty minutes of work for 250 € in savings, and the pride of saying, “I did it myself!”
Josmose.fr : economical alternatives for all your water treatment equipment
We've just told you about our RO systems, but we offer many other products to help you get good-quality water. Our philosophy is to sell you only equipment that meets your needs and your own consumption, and above all, to give you the knowledge you need to use it along with the equipment itself. We're sellers, but we're also passionate about and committed to conserving water on our planet, and dedicated to helping people drink purer water that will protect their health.
On josmose.fr, we therefore offer a wide range of water softeners that help you fight limescale, a problem that affects every home to varying degrees depending on the region. You can also choose one or more ultrafiltration systems that make water sanitary and remove bacteria. These systems are essential and often widely used by people who use rainwater or well water.
Finally, whatever product we offer on josmose.fr, we work to give you all the information you need to use and maintain it independently and get the benefits it can provide.
We believe that a well-informed customer who has the right equipment, isn't held hostage, and remains free to come and go and change suppliers is a happy customer. And therefore a loyal one. So if you buy an OJA RO system or any other product or equipment from our Josmose.fr website, you remain free to change your membrane or kit supplier. This is certainly what sets us apart from other businesses in the water industry : we do more than sell our products. We offer expertise and relevant advice, and we respect our customers : an approach that makes all the difference and gives Josmose.fr its value.
