No worry about losing filtered water during power outage

With KAD-N89, the worry of losing power and not being able to get filtered water will be no more. Now users can get the water purifier when the power is out thanks to the design of the lock valve and the smart backup accumulator.

3.4 Anti-overflow sensor technology – Instant water shutoff

Anti-overflow sensor technology – Instant water shutoff

For the first time, sensor technology to prevent overflow has been equipped on a water filter in Vietnam. The overflow prevention sensor works when it detects water on the surface of the machine, immediately causing the Karofi KAD-N89 hot and cold RO water purifier to automatically shut off the water to prevent electrical shock and water waste. This helps users feel more secure during the use of the water filter.

3.5 Leading the trend of smart water purifiers with AIOTEC technology

The KAD-N89 is equipped with AIOTEC smart technology that allows users to easily control the water filter from anywhere, at any time. With the Karofi 365 application, you can easily check the water cleanliness level, replace the filter cartridges in a timely manner, monitor the status of the machine, or activate warranty services and contact customer care quickly and conveniently.

3.6 Gold Line Infinity design

3.7 The clean water meets the standard of purified bottled drinking water QCVN 6-1:2010 MOH

QCVN 6:1-2010/MOH is the highest standard for direct drinking water in Vietnam, recognized by the Institute of Occupational and Environmental Health - Ministry of Health according to WHO procedures. To meet this standard, water must go through a rigorous testing process with 21 physicochemical criteria and 5 microbiological criteria to ensure safety and quality.

Due to the application of advanced filtration technology, the water after being filtered from the Karofi KAD-N89 hot & cold RO water purifier meets the standard of pure water equivalent to bottled water according to QCVN 6-1:2010 of the Ministry of Health.

Therefore, every member of the family can drink directly without boiling while ensuring safety and providing the necessary source of minerals for the body.

4. Powerful 10 stage filtration system

Powerful 10 stage filtration system

The new generation Smax Pro filter system with 10 powerful smax filters provides outstanding high efficiency, helping the filter elements to both double the capacity and double the life of the filter cartridge.

4.1 New generation of pre-filters Smax Pro

Pre-filter Smax Pro 1

Constructed by a multi-point, multi-bonded microfiber filter sheet with a size of only 5 micrometers and arranged in a smart fan folding structure, the Smax Pro 1 filter has an optimized design that increases the water contact area by three times that of a regular filter, enabling faster filtration and reducing the risk of clogging. With a filtration efficiency twice as high as that of a regular filter, the Smax Pro 1 filter removes various impurities such as debris, sand, sediment, algae, and solid particles smaller than 5 micrometers, and has a lifespan of up to 12 months - twice as long as that of a regular filter.

New generation of pre-filters Smax Pro

Smax Pro 2

The special feature of Smax Pro 2 filter comes from a unique 2-layer structure: the outer layer is a filtration membrane made up of small-sized interconnected fiber strands, combined with an activated carbon layer on the inside.

Specifically, the filtration membrane in the outer layer helps to remove impurities, dirt, algae, etc. while the activated carbon layer on the inside helps to effectively treat organic substances, odor-causing compounds, colorants, and chlorine in household water.

The Smax Pro 2 water filter not only doubles the effectiveness of water filtration but also doubles the lifespan compared to conventional filters

Smax Pro 3

Produced and researched on modern production lines, undergoing high-temperature heat treatment and utilizing the new Smax Pro technology, the Smax Pro 3 filter provides superior filtration efficiency.

The special feature of the Smax Pro 3 filter comes from its 5-layer structure of multi-point bonded microfiber filter membranes, with ultra-small micron sizes arranged in a smart fan-fold structure.

Furthermore, the Smax Pro filter core helps remove impurities and contaminants that the Smax Pro 1 and 2 filter may have missed, contributing to an increase in filtration efficiency and the lifespan of the RO membrane

4.2 Smax RO

The most important component in the Purifim RO membrane is the reverse osmosis membrane, which is specially constructed from tightly bound and coiled TFC (Thin Film Composite) organic fibers to form a spiral structure. The surface of the membrane is made up of small holes about 0.1-0.5 nanometers in size, allowing only water molecules to pass through and removing most bacteria, heavy metal ions, and impurities in the water.

SMAX is an optimal membrane structure design technology, first applied in RO membrane design. With SMAX, the area of the membrane in contact with water is maximized within the same 1.8x12 inch membrane size, increasing the maximum water flow through the membrane, thereby enhancing filtration capacity and extending the lifespan of the membrane.

Strong Flow - Faster filtration: By maximizing the area of the membrane in contact with water, the Purifim filtration capacity doubles that of the RO membrane on the market.

Super Permeate - Better permeation: The pure water recovery rate of the Purifim RO membrane is 60%, reducing up to 71% of wastewater compared to ordinary RO membranes.

Strength life - Longer lifespan: The lifespan of the Purifim membrane is 24-36 months, 1.5 times longer than the RO membrane on the market - with a lifespan of 18-24 months.

Developed in collaboration with leading experts at Karofi and the United States, the Purifim RO membrane is manufactured on modern American production lines, creating a breakthrough in RO filtration technology today:

Applying the latest manufacturing technologies

Developed to be suitable for the characteristics of all water sources.

The Purifim RO membrane operates stably with an input water source with a TDS index of up to 1000ppm (compared to typical RO membrane products of only 500ppm), combined with the support of 3 coarse filters, effectively treating a variety of water sources.

4.3 Upgrade functional filtration system - Double Hydrogen

Upgrade functional filtration system - Double Hydrogen

The  functional filtration system is not only designed with modern technology and a solid block to prevent maximum leakage and easy replacement, but it also doubles the amount of Hydrogen with the presence of the entirely new Hydrogen Plus filter. The simultaneous combination of 3 filters: Orp Alkaline, Tourmaline, and Hydrogen Plus helps the water have an optimal Hydro, pH, and Orp for the user's health.

T33-GAC filter: superiorly handles odors, organic matter, and makes the water taste sweeter.

Mineral filter: supplements beneficial minerals and raises pH, helps neutralize excess acid, and makes the water taste better.

ORP Alkaline filter: reduces water ORP to enhance the immune system and raise water pH, supports neutralization of excess acid, and supplements beneficial minerals and electrolytes for the body.

Hydrogen Plus filter: supplements Hydrogen to help reduce harmful oxidants and radicals in the body, while also raising the pH for good digestive health.

Tourmaline filter: made from tourmaline and bioceramic particles, helps create beneficial negative ions, reduces harmful factors for the body, and activates water to make it easier for the body to absorb.

NanoSilver filter: destroys bacteria, positioned at the final stage of the water filtration system to prevent recontamination after passing through the water filtration system.
