Fine bubbles can be broadly categorized into microbubbles, which are bubbles between 1-100 μm, and ultrafine bubbles, which are smaller than 1 μm.
Typically, microbubbles disappear (dissolve) within 5 to 10 minutes. Ultrafine bubbles, on the other hand, have been confirmed to remain in water for several months without disappearing. However, their stability can vary depending on environmental factors such as temperature and vibration. They may also collapse when exposed to water flow or impact. Therefore, we cannot guarantee how long fine bubbles will last.
Note: Unit: μm/micrometer
Hydrophobic = not very soluble in water, like oil. Both fine bubbles and dirt are hydrophobic, which allows fine bubbles to attract and lift dirt to the surface.
Yes, it can.
EcoCute has a storage unit called a "thermal tank," where hot water and cold water are stored. When water is left at a high temperature for a long time, dissolved air in the water may be released as bubbles, which can result in a slight reduction in the number of bubbles. However, since the hot water is mixed with room-temperature tap water when used, the reduction in bubbles is expected to be minimal.
No, it cannot be used with a balanced-flue water heater.

[For detached houses]
The secondary (downstream) water pipe of the water meter buried in the ground on the property is cut, and this product is installed. If the ground is soil, it will be dug up. If the ground is concrete, it will be drilled for installation. In both cases, a box with a lid (such as a water tap box) will be installed at the installation point so that the product can be inspected.
* If the water pipe is buried deeply, such as in cold regions, the product may be installed underground without a box.
[For condominiums]
The connection of the water pipe on the secondary (downstream) side of the water meter installed in the pipe space outside the entrance is removed, and this product is installed. After installation, the pipe will be wrapped with heat-insulating material, so the product will no longer be visible.
* Please obtain permission from the management company, homeowners association, or similar entity in advance if installing it in rental properties or for-sale condominiums.
