Compliment your cleaning collection with the RYOBI Stick Vac Replacement Filter. This filter traps 99.9% of allergens and prevents dust and pet hair from being circulated back into the air as you vacuum. Easily remove the filter from the dust cup by pulling on the blue tab. This filter can be washed with soapy water and must air dry for at least 24 hours before being used again. Replace your filter every 3-6 months for maximum performance. This replacement filter is compatible with the RYOBI PCL720 18V ONE+ Cordless Stick Vac, the PBLSV716 18V ONE+ Cordless Pet Stick Vac, and the PBLSV717 18V ONE+ Cordless Pet Stick Vac with Dual Roller Bar.
