UrQuelle® Diamant in Review - Is the reverse osmosis system really that good?

06 Nov 2025

In our water filter kitchen, we regularly test the best water treatment systems on the market. Today's focus: the UrQuelle Diamant – one of the most exquisite and technologically sophisticated water filter systems we have tested so far. 

But how good is the German manufacturer's reverse osmosis system in practice?

The manufacturer's promise: The water filter combines precise filtration with elaborate remineralization and energization, thereby delivering not only pure but also vitalized drinking water of the highest quality - let's see!

Structure and Functionality

Opened - and immediately amazed. The filter design is clear and functional, yet very high-quality. The lid can be magnetically removed – tool-free, secure, and genuinely practical. Inside is a three-stage pre-filtration system that removes coarse particles like rust, sand, or lime sediments.

Subsequently, the water passes through a 600 GPD high-performance membrane with a filter fineness of 0.001 micrometers. This means: Only the water molecule itself can pass through – pollutants, heavy metals, microplastics, pesticides, and drug residues are reliably removed.

This system lays the foundation for absolutely pure water – the subsequent refinement makes all the difference.

Remineralization and Energization

After filtration, the water is remineralized and energized in several stages. This process uses Sango corals, Myfan stones, and rock crystals. These return valuable minerals and energetically restructure the water. The result is soft, harmonious, and biologically active drinking water.

A central element is the implosion vortex unit, where the water is swirled and simultaneously enriched with natural frequencies. This is followed by UMH swirling made of 24-carat gold-plated brass, whose surface has been specially designed for particularly pure vibration transmission. In some versions, a real rock crystal is additionally integrated into the faucet, completing the energization process.

This combination of physical structuring and natural mineral replenishment is unique and ensures vital, lively water with a hexagonal structure.

The Practical Test

Naturally, we wanted to know how the Diamanturquelle performs in practice. In our test, the system required 24 seconds for 0.5 liters, meaning a flow rate of approximately 48 seconds per liter of water. The noise level was 57 decibels – pleasantly quiet and barely noticeable during operation.

The water quality measurements speak for themselves:

  • Tap water: 325 ppm
  • Filtered, unmineralized water: 2 ppm
  • After remineralization: approx. 15 ppm

The increase after energization shows that minerals are indeed being returned. This creates optimally balanced drinking water – cleanly filtered, lightly mineralized, and structured.

Operation and Maintenance

The Diamanturquelle is designed so that even less technically experienced users can operate it without problems. Filter changes are made without tools; the system is clearly structured and easily accessible. Thanks to high-quality materials and automatic flushing processes, the system remains hygienic and low-maintenance in the long term.

Conclusion of our Test

The Diamanturquelle is one of the most technically and energetically sophisticated systems on the market. It achieved the best value we have ever measured after filtration, at 2 ppm. It combines excellent filtration performance with one of the highest quality remineralization and energization units we have tested to date.

The water tastes exceptionally soft, fresh, and lively – and achieves an optimal mineralization level with a residual value of approximately 15 ppm. Particularly convincing is the combination of easy handling, quiet operation, and uncompromising material quality.

For anyone who values more than just clean water, the Diamanturquelle is a clear recommendation. It offers not only purity but also vitality – water that noticeably conveys energy and balance.

Blue Nature Services then usually sends an (automatic) "order confirmation" by email, which merely documents that the customer's offer has been received by Blue Nature Services. A contract is not yet concluded at this point. Orders placed are binding for the customer. Unless explicitly acknowledged otherwise, there is no right of return or withdrawal for the customer. The contract is only concluded upon acceptance by Blue Nature Services or (implicitly) by dispatching the ordered goods. Orders will only be delivered after full payment has been received (exception: delivery against invoice) and if the goods are available. If, after the conclusion of the contract, it turns out that the ordered goods cannot be delivered or cannot be delivered in full, Mein-Wasserfilter is entitled to withdraw from the entire contract or a part of the contract. If the customer's payment has already been received by Blue Nature Services, the payment will be refunded to the customer in full or proportionally.

Blue Nature Services may charge default interest of 5% per year and a reminder fee of Euro 20.- per reminder in case of late payment by the customer. The customer expressly acknowledges the costs for collection and default damages charged by Blue Nature Services. The products delivered to the customer remain the property of Blue Nature Services until full payment has been received. Blue Nature Services reserves the right to withhold further deliveries or to refuse them entirely in case of non-acceptance of ordered goods or late payment. In such cases, the customer agrees to compensate Blue Nature Services for the damage caused thereby. The customer will only choose the "Payment by invoice" option if they are willing and able to correctly adhere to the payment deadline specified on the invoice and to pay the invoice amount in full. Otherwise, the customer will choose the "Credit card", "Prepayment", or "PayPal" payment option. If the customer chooses the "Payment by invoice" option and does not pay the invoice, the customer expressly accepts the accusation of deliberately causing damage to Blue Nature Services with all the resulting legal consequences and costs. 6. Delivery, inspection obligation, notice of defects, and returns Deliveries are usually sent by post or courier service to the address specified by the customer in the order. Invoicing is done by email or by post. The benefit and risk pass to the customer upon dispatch, as far as legally permissible. If the delivery is undeliverable or the customer refuses to accept the delivery, Blue Nature Services may withdraw from the contract and charge for the costs incurred. The customer is obliged to inspect the delivered goods immediately upon receipt of the delivery and to notify Blue Nature Services immediately in writing by letter or email of any defects for which Blue Nature Services is liable. Returns to Blue Nature Services are at the expense and risk of the customer.

It is at the discretion of Blue Nature Services to provide warranty by equivalent replacement or by refunding the purchase price. Further claims are excluded. Normal wear and tear, as well as the consequences of improper handling or damage by the customer or third parties, and defects due to external circumstances, are not covered by the warranty. The warranty for consumables and wear parts is also excluded. Blue Nature Services cannot provide assurances or guarantees for the timeliness, completeness, and correctness of the data, nor for the constant or undisturbed availability of the website, its functionalities, integrated hyperlinks, and other content.
