Using the Mica 3 - Way Filter Sink Mixer is easy. Just connect it to your sink following the instructions. Make sure to use a 1/4 inch hose filter kit for proper filtering. For daily use, turn the handles to control the water flow and temperature. Remember, the filter is not included, so you'll need to get one separately. When it comes to maintenance, clean the mixer regularly with a mild cleaner to keep it looking shiny. Avoid using abrasive materials as they may scratch the brushed gold finish. If you have any issues, refer to the warranty guide for support.
