The Ultimate Multipurpose RO Kitchen Filter for Drinking, Cooking and Rinsing

The Maxi RO-Filter is a larger-capacity system designed for households that require high-performance filtration for general kitchen use, while still having the ability to produce RO-purified drinking water.

Its enhanced flow rate makes it suitable for everyday activities such as rinsing food and filling containers, while also producing Reverse Osmosis water—the cleanest form of water available.

RO systems are the only filtration technology capable of removing virtually all contaminants, including:

• Bacteria
• Chemicals
• Heavy metals
• Dissolved contaminants
• Beneficial minerals

Although RO water is technically pure and safe, it is also mineral-depleted, sterile and acidic. It is therefore not considered ideal for long-term human consumption without remineralisation.

To transform RO water into Healthy Living Mineral Water, simply add Hidro+ Mineral Concentrate. This specially developed concentrate restores vital minerals and alkalinity to support hydration, energy and general well-being.

Why a Larger-Than-Standard RO Filter Is the Smart Choice

High Flow Rate for Kitchen Use

Standard small RO units typically produce approximately 7 litres of water per hour. The Maxi RO-Filter produces up to 60 litres per hour, making it far more practical for kitchen activities such as rinsing food, filling containers and preparing meals. Small RO units generally cannot provide sufficient water flow for these everyday applications.

Greater Output Efficiency

Although the Maxi RO-Filter costs approximately twice as much as a small RO unit, it produces around eight times more water.

This makes it a more practical and cost-effective solution for families and food-preparation environments that require a reliable supply of purified water.

No Contaminated Storage Tank Required

Small RO units require a pressurised bladder accumulator to temporarily increase the water flow.

Over time, these tanks may harbour bacteria and cannot be cleaned properly. Even with an accumulator tank, the resulting water flow may still be insufficient for practical kitchen use.

The Maxi RO-Filter’s higher production capacity eliminates the need for this type of contaminated storage tank.

Faster Filling and Fewer Risks

The system’s high output allows containers to be filled more quickly when preparing water for remineralisation with Hidro+ Mineral Concentrate. Faster filling reduces frustrating delays and lowers the risk of forgetting to close the water supply, which can lead to spills and unnecessary cleaning.

Exceptional Water Purity

Although the annual cartridge replacement cost is higher than that of a smaller filtration unit, the Maxi RO-Filter provides the highest level of water purity achievable with a household filtration system.

Features and Requirements

• Requires electrical power
• High flow rate of up to 60 litres per hour
• Annual cartridge replacement cost of approximately R1,000, based on 2024 pricing
• Includes a deep, self-draining drip tray to protect kitchen cupboards
• Suitable for DIY installation
• Professional installation is available within 16 kilometres of the Hidro+ shop
• Courier delivery is available for units, replacement cartridges and Mineral Concentrate
  
  

For households that are serious about clean, healthy water, the Maxi RO-Filter provides a professional-grade kitchen filtration solution.

The Hidro Tap Safe Kitchen Water Filter

Advanced Four-Stage Filtration With a Backwash Facility

The Hidro Tap Safe is a newly designed and unique four-stage kitchen water filter that provides exceptional performance, ease of use and long-term value. It is designed as the ideal minimum filtration requirement for safe, everyday household water use.

What Sets the Hidro Tap Safe Apart?

Unlike conventional kitchen water filters, the Hidro Tap Safe provides:

• 100% full-flow capacity, compared with approximately 20% flow capacity from typical under-sink RO systems
• Advanced ultrafiltration that removes harmful contaminants without stripping the water of essential minerals
• Proprietary ISO-GRAM filtration technology that removes heavy metals and radioactive isotopes—a rare but important capability not found in most conventional kitchen filters.
  
  

What Does the Hidro Tap Safe Remove?

Chlorine

The system removes chlorine, which is described as a known carcinogen commonly found in municipal water.

Bacteria

The filtration system removes harmful bacteria and microbes, including E. coli.

Biological Oestrogen Hormones

The Hidro Tap Safe removes biological oestrogen hormones that may disrupt the body’s natural hormonal balance and may be particularly harmful to boys and men.

Microplastics

The system removes microplastics, which are synthetic endocrine disruptors now found in many water sources around the world.

Heavy Metals and Radioactive Isotopes

Hidro+’s exclusive ISO-GRAM technology removes heavy metals and radioactive isotopes from the water.

Unpleasant Tastes, Odours and Particles

The system removes unpleasant tastes, odours and particles by filtering water down to 0.01 micron—finer than the size of bacteria.

Ideal Applications

The Hidro Tap Safe is suitable for:

• Rinsing food
• Cooking
• Everyday drinking water
• Households seeking safe, mineral-retaining water
• Households that want the option of enhancing their water’s mineral content by adding Hidro+ Mineral Concentrate
  
  

Key Features and Benefits

• No electricity required
• High flow rate of up to 60 litres per hour
• Suitable for practical everyday kitchen use
• Includes a deep, self-draining drip tray to help prevent cupboard damage
• Low annual running cost
• Suitable for DIY installation
• Professional installation is available within a 16-kilometre radius of the Hidro+ shop
• Nationwide courier delivery is available for filters, ISO-GRAM cartridges and Mineral Concentrate
  
  

The Hidro Borehole-Safe Kitchen Water Filter

Three-Stage Filtration With Automatic UV Disinfection

The Hidro Borehole-Safe is a unique three-stage kitchen water filter designed specifically to improve the safety and quality of borehole water.

The system combines Hidro+’s proprietary ISO-GRAM filtration cartridge with a UV disinfection light, providing enhanced filtration, safety and performance.

The UV light is activated only while water is flowing through the system. This prevents the water from heating up, as heated water within a filtration system could create conditions that encourage bacterial growth.

This intelligent on-off UV design makes the Hidro Borehole-Safe particularly effective for borehole water, which may become contaminated with bacteria.

The system filters water down to 1 micron, helping to ensure that it is safe for drinking, cooking and rinsing food. It also maintains a high water flow rate that substantially exceeds the flow provided by traditional small RO filters.

Why the Hidro Borehole-Safe Is a Better Choice

High Flow Rate

The Hidro Borehole-Safe provides a water flow rate of approximately 7 litres per minute, compared with approximately 7 litres per hour from a small RO system. This makes rinsing food and performing other kitchen tasks faster, safer and more practical.

Low Annual Maintenance Cost

The annual cartridge replacement cost is approximately R400, based on 2024 pricing.

UV-C Disinfection

The UV-C light effectively destroys harmful bacteria, including E. coli, without heating the water.

Heavy Metal and Radioisotope Removal

Hidro+’s exclusive ISO-GRAM filtration technology removes heavy metals and radioactive isotopes from the water.

Ideal for Borehole Water

The combination of ISO-GRAM filtration and UV-C disinfection helps maintain the safety of borehole water, even when bacterial contamination occurs.

Features and Specifications

• Removes harmful bacteria, including E. coli
• Produces water suitable for drinking, cooking and rinsing food
• Removes heavy metals and radioactive isotopes
• Removes unpleasant tastes and odours
• Filters particles down to 1 micron
• Requires electrical power for UV operation
• Includes a deep, self-draining drip tray to help protect cupboards from water damage
• Suitable for DIY installation
• Professional installation is available within a 16-kilometre radius of the Hidro+ shop
• Courier delivery is available for filtration units, ISO-GRAM cartridges and Hidro+ Mineral Concentrate
  
  

Mineral Concentrate Recommendation

When borehole water contains a low level of minerals, indicated by a Total Dissolved Solids measurement below 120 parts per million, Hidro+ recommends adding Mineral Concentrate.

The Mineral Concentrate can improve the water’s mineral content, overall quality and potential health benefits.
