The Roborock S8 HEPA Filter is designed to maintain the suction power and airflow of your vacuum, ensuring your home stays clean. It is compatible with the S8, S8+, S8 Pro Ultra, and G20 models, featuring an edge-wrapped design that prevents dust from leaking back into your living space. This white filter measures 135 x 57 mm and captures tiny particles as small as 0.3 microns, including pollen, mites, and other common allergens. Because it is washable and reusable, you can simply clean it every two to four weeks to keep it efficient, provided it is completely dry before you put it back in. Replacing the filter is a straightforward, tool-free process, making it easy for any user to keep their device running smoothly.
