This HEPA filter needs to be maintained at all times for consistent suction by your IPC Eagle Pulsar vacuum. If the HEPA media becomes contaminated, it will not allow your vacuum to perform at its maximum ability causing some debris to either not be recovered or exhausted back into the air. The HEPA cartridge filter is the single most important element for the now discontinued Pulsar mold, lead & asbestos recovery vacuum to function properly. It will also fit on the 315P-H vacuum.
The and the are another key element to making your vacuum function at 100% of its capacity. The cloth bags, as well as these replacement filters are sold as single packs. The paper/disposable bags are sold in 3 packs.
