If you keep your stomach full of waste your body doesn't need for too long, you'll have to detox, diet, and exercise to return it to normal. Your Eureka Optima vacuum on the other hand has the luxury of a removable dust cup, so you can just pull it out, empty it, wash it, and put it back in. Now wouldn't that be nice for you! Make sure you keep your vacuum in tip top shape with this two-pack of Eureka washable dust cup filters. Each HEPA DCF10 filter offers up to 99.97% filtration, so your air stays as clean as possible while you vacuum.
