Description

Biologically clean hydration in a compact format. Designed specifically for cats and small dog breeds, which are often picky about tap water. Molecule Mini revolutionises everyday care with a distinctive, elegant transparent “squircle” (rounded square) design that fits perfectly into any modern interior.

The H2Q™ Activator at the bottom of every drop Through the thick, crystal-clear bottom of the bowl, our distinctive blue and white H2Q™ module is clearly visible. This patented system changes the physico-chemical properties of water, breaks down heavy minerals and structures the molecules. The result is soft, biologically recognisable water that enables faster cellular osmosis and significantly reduces the load on your pet’s kidneys.

Medical-grade safety and Anti Bio-Film protection Your pet deserves top-level safety. The bowl is made from Kostil® B 266 material, a highly transparent copolymer that offers exceptional chemical resistance and is used in the manufacture of medical and pharmaceutical instruments. Unlike ordinary plastic or steel, our Anti Bio-Film surface helps prevent unpleasant slime and bacterial buildup on the bowl walls.

Luxury packaging Molecule Mini comes in our premium white box with minimalist blue branding and a central circular cutout that immediately reveals the H2Q technology. It is also ideal as a luxury gift for any responsible owner.

Frequently asked questions and answers

What are the dimensions of the MOLECULE bowl?
  • Large bowl: 196 × 196 × 75 mm
  • Small bowl: 196 × 196 × 45 mm
What is the MOLECULE water bowl made from?

For the MOLECULE water bowl, we selected Kostil – a high-quality plastic known for its wide use in the food industry, as well as in products intended for children and babies. Our goal was to provide maximum safety and reliability for your pets.

How often should the water in the MOLECULE bowl be changed?

Although the H2Q device acts on the water continuously for as long as it is in the bowl, we recommend changing the water at least once a day, ideally twice – in the morning and in the evening. The reason is not H2Q – but the natural build-up of saliva, food particles and contact with the environment, which affect the freshness of the water.

Approximate daily water intake for pets:

  • Dog: ~50-60 ml per kilogram of body weight (10 kg dog → ~500-600 ml daily)
  • Cat: ~40-60 ml per kilogram of body weight (4 kg cat → ~160-240 ml daily)

These approximate figures help you decide between the 350 ml and 800 ml formats.

How can I be sure the material is safe?

The MOLECULE water bowl is the result of more than 40 years of scientific research. The effect of the MOLECULE water bowl on water was tested at the Institute for Biological Research, and all materials are high quality.

Specifically, the only material in contact with your pet’s drinking water is “Kostil® B 366″ (manufacturer – Versalis), which has relevant certificates for health safety when used in water and food bowls:

Certifications and compliance:

  • NSF 51 certificate – confirms that the material is suitable for direct contact with food and water, in accordance with standards for plastic components in the food industry.
  • UL 94 (HB classification) – a standard for plastic flammability which, although not directly related to health safety, indicates additional safety characteristics of the material.
  • Declaration of compliance – the TDS document states that “in its original packaging, due to its composition, it complies with applicable regulations on plastic materials intended for contact with food”.

Accordingly, Kostil® B 266 meets the health-safety requirements needed for use in the production of water and food bowls.

How quickly does water become treated in the MOLECULE bowl?

The water is treated after only a few seconds. The H2Q device works for as long as the water remains in the bowl.

How long does the effect of the H2Q device last? Does it need to be replaced?

The device uses no energy, has no filters, and does not require replacement. Its effect is permanent as long as the bowl is used properly – there is no expiration date.

What if the MOLECULE bowl breaks?

The product has no electronic or moving mechanical parts, which means there is nothing to break.

How is the MOLECULE bowl washed and cleaned?

Yes, it is recommended to wash the MOLECULE water bowl by hand, using mild, non-aggressive cleaning agents to preserve its durability and functionality.

Can the MOLECULE bowl be washed in a dishwasher?

The MOLECULE water bowl is not intended for machine washing of any kind because of the harmful effect on the H2Q device.

Can I use MOLECULE outdoors (terrace, yard, walk)?

Yes, the MOLECULE bowl can also be used outdoors, with a few practical notes:

  • Prolonged direct sunlight – we recommend that the bowl not stand for hours in strong sun; prolonged UV exposure weakens all plastic materials over time, including Kostil® B 366.
  • Low temperatures and frost – water that freezes can crack the bowl and damage the H2Q component.
  • Walks – for travel, we recommend the smaller 350 ml format, which is easier to transport.

The bowl is not intended for use in aquariums or continuously submerged environments.

Biologically clean hydration. A revolutionary water system designed to support better health and longevity for your most loyal friends. Clinically proven in Serbia and Europe through independent research.
