While conventional warm water cleansing toilet seats rely on a motor to power the cleansing function, the Kirei series takes a different approach. Instead of using a motor, the Kirei seats generate water pressure directly from the water supply to expel cleansing water.

Electricity is only used to heat the toilet seat and the cleansing water.

This innovative design makes the Kirei series a true hybrid, combining water pressure and electricity for a more efficient, reliable, and maintenance-friendly experience.

Turning Everyday Life into Disaster-Ready Living: Be Prepared for Hurricanes and Earthquakes

For everyday use, the Kirei PLUS offers the best of Japanese technology with features like:

• Warm toilet seats
• Warm water cleansing

Even during power outages in emergencies, as long as the water supply is available, the rear and front cleansing functions remain operational. This unique feature of Kirei PLUS:

• Reduces the need for toilet paper during disasters
• Helps maintain hygiene when resources are limited

Key Advantage:
Unlike other products, which cannot be used during power outages, the Kirei PLUS relies on water pressure as its power source. This means there are:

• No concerns about clogging
• Reliable performance worldwide, even in challenging conditions

Environmentally Friendly Instant Heating
The Kirei PLUS uses an efficient, on-demand heating system that only heats water when you’re using it for cleansing. This helps save electricity and reduces environmental impact.

Carbon Neutral Products
The cleaning function can operate solely on water pressure, so when you’re not using hot water or a heated seat, the system can be turned off. This means no electricity is consumed for the cleansing function.

Energy Usage
The only power consumption is approximately 1 kWh per year for the cleaning knob, making it incredibly energy-efficient and environmentally friendly.

Simple Filter Cleaning Prevents Lime Blockages
Lime buildup from hard water is a common cause of malfunctions in areas with high mineral content. To address this, the Kirei PLUS makes it easy to clean the filters, preventing blockages and ensuring consistent performance.

A Solution for Hard Water Areas
In the United States, the adoption of bidet seats like those in Japan has been slow, primarily due to the challenges posed by hard water in municipal supplies. However, with the Kirei PLUS, if the water pressure or cleansing function is reduced due to hard water, simply cleaning the filters of the branch connector and water supply hose will restore full functionality.

Durable, Easy Maintenance
The metal construction of the connecting parts allows for secure, tool-assisted fastening during filter cleaning and replacement, ensuring long-lasting durability and easy maintenance, even in hard water areas.

Safety Features
The Kirei PLUS is designed with your safety in mind. It automatically reduces the temperature after 5 minutes of use to prevent the risk of low-temperature burns. Additionally, if the water temperature reaches 43°C, the system automatically stops the cleansing water flow and switches to self-cleaning mode, ensuring safe and comfortable use at all times.

Additionally, during warmer months, you can turn off the warmth mode to significantly reduce electricity costs. This feature is unique to the Kirei PLUS, as it allows the cleansing function to operate using water pressure alone, without the need for heated water.

Automatic Nozzle Cleaning Function
The Kirei PLUS features an automatic nozzle cleaning function for enhanced hygiene. When you sit on the seat, the nozzles are automatically cleaned by flushing water for about 5 seconds. Additionally, after each use of the cleansing function, the nozzles are automatically cleaned again by flushing water for about 2 seconds, ensuring a clean and sanitary experience every time.

The toilet seat cover features a slow-closing mechanism, gently lowering to prevent any damage to the seat or lid.

Equipped with patented nano-bubble generation core

We have made it possible to equip Japan’s cutting-edge nanobubble generator technology to the toilet’s water shut-off valve. By integrating it with a warm-water bidet, it provides not only targeted cleaning with nanobubbles but also helps prevent stubborn toilet stains and control odors effectively.

Approximately 66 million nanobubbles are generated per milliliter.

Nanobubbles are air bubbles with a diameter of 100 nanometers. In contrast, the diameter of a pore is typically around 20-500 micrometers (µm). A micrometer is a unit larger than a nanometer (nm) by a factor of 1,000.

In the United States, nanobubbles are defined as extremely small gas bubbles with diameters typically less than 100 nanometers (nm).

NanoWash’s nano bubble unit is Japan’s most innovative technology. Nanobubbles are much smaller than microbubbles and have the unique characteristic of existing very stably in liquids. A standard for being classified as a nanobubble is that its diameter is less than 1/1000th that of a microbubble.

Due to their tiny size, nanobubbles have the following characteristics:

1. Stability: Nanobubbles are much more stable than regular bubbles and can exist in water for extended periods.
2. Large Surface Area: Because of their very small size, the same amount of gas forms nanobubbles with a much larger surface area compared to regular bubbles.
3. Unique Physicochemical Properties: Nanobubbles exhibit different behaviors compared to regular bubbles, affecting water solubility and reactivity.

Nanobubbles are utilized in various fields, including environmental remediation, agriculture, healthcare, and food processing. Their small size and unique properties make them effective in promoting certain chemical reactions and removing microscopic contaminants.

In the United States, research and application of nanobubbles are advancing, with various industries exploring their potential uses.

Nanobubbles have a negative charge on their surface and are surrounded by a shell of condensed ions, meaning they are coated with negative ions.

The nano bubble cleansing water is jet-sprayed to gently and thoroughly clean your bottom and delicate areas.

Even stool that adheres stubbornly to the wrinkles and crevices of the anus can be easily removed as the nano bubbles ionically attract and lift away the dirt.
