Micro/Hospital-Grade Filter for C Series Vacuums Filters the R17 glides across themThis Micro Hospital Grade Filter for C Series Vacuums is a replacement filter that traps dust, allergens, and fine particles to maintain clean air exhaust. Regular filter replacement keeps your vacuum running at peak suction and extends motor life. Check your filter every 1 3 months and replace when visibly dirty or when suction decreases. A clogged filter forces the motor to work harder, reducing cleaning performance and shortening motor life. Always
