The water purifier is easy to handle and the cartridge is easy to replace, and it doesn't take up much storage space. Approximately 3 months (when using 13L per day). The lifespan of the filtration capacity may be significantly shortened depending on the amount of use, water pressure, water quality (turbidity, red rust, etc.), the cleanliness of the water supply equipment, the aging of the pipes, and plumbing work. Water purifier cartridges that have exceeded the replacement time may not provide sufficient water purification capacity.
