They come in a set of four, so they can be washed and replaced. We recommend replacing them when they become clogged. Buy and replace them regularly to keep them clean. [Replacement Frequency] If the filter becomes clogged with debris, suction power will decrease. To prevent this, clean the filter regularly. We recommend replacing it every 3-6 months. The filter lifespan will vary depending on the time of use and the environment. [Restore suction power] Over time, filters can become torn or deteriorate during daily cleaning, requiring replacement. This product is cheaper than the original and can be used without any problems. It thoroughly sucks up even the smallest particles, and replacing it restores suction power! This is an optional exhaust filter for the cleaner.
