Genuine 6 Riccar charcoal bags are designed to precise specifications to trap particles and to reduce dust leakage and breaking.
These bags have a yellow self-sealing bag collar and are for the Radiance R40 and R40P or Simplicity S40 and S40P upright vacuums.
New charcoal lining still filters particles 99.97% of particles down to .3 microns. Now it also reduces odors in the vacuum.
These bags will not fit RADP or RAD models. See part RXH-6.
If you used the old RPH-6 bags, this is it's replacement.
