Vacuuming is one of those chores that most people wish they could avoid. Not allergy sufferers, however. Those of us who sneeze from the slightest hint of cat or plant matter love to run our high efficiency allergy vacuums weekly, or even daily, knowing that we're sucking up irritants. Still, sometimes we forget that to keep our vacuums running smoothly, we have to change out our filter. That's where this filter kit comes in. It has both the regular filter to get the big stuff (pet hair, and large dust) and the HEPA filter that traps the small stuff (dust mites, mold spores, little dust). These filters also make it easy because they're washable and reusable. Just rinse every four to six weeks and let air dry. Once they're dry, you're good to go.
