i-Wave Cleaning Technology

When developing Bidetmega, LivingCare Development Team Leader Sung Worl Jin was inspired by things in his daily life. When work first began on Bidetmega, Jin and his team were researching which current of water pressure gave the right balance for cleanliness and comfort. “Water pressure is key to the use of the bidet. If the water pressure is too strong, it may affect overall anal health,” says Jin.

Then one day, Jin saw their daughter playing with a rubber hose, and realized the flexibility of the hose could help with the bidet’s water path. Coway’s now-patented i-Wave technology gives a multiple-stage wash with different pressures, allowing for maximum cleanliness, and a more gentle experience.

i-Wave consists of four stages: Soft Start, Pre Wash, Main Wash and Rinse Wash. The first three stages slowly build water pressure to go from a gentle to a thorough clean, and the final stage ends with a refreshing finish.

Result showed each product effectively removed over 99.98% of the SARS-CoV-2 in 2 minutes. This is a result from a laboratory experiment condition and result may vary in different conditions. This result does not imply it kills SARS-CoV-2 or prevents the transmission of Covid-19.

5The coverage area of the air purifier is based on an area where the air cleaner can make two air changes per hour (ACPH). An air change per hour translates to how many times an air purifier can clean an area, assuming the height of a ceiling to be 8 ft, in one hour. Therefore ** means two air changes per hour means that the cleaner can clean the area once every 30 minutes and * means air changes per hour means that the air purifier can clean the area once every 60 minutes.
