Hey Oreck owners! These PETOX vacuum bags are exactly what you need to keep your magnesium upright vacuum running like new. This 6-pack of Type LW bags fits perfectly with models that use part numbers LWPK6OH, LWPK25OH, and LWPK3OH - but definitely double check your vacuum model before buying! The coolest thing about these bags is the 6-stage filtration system - they've got plastic, activated carbon, hot air cloth, and three layers of premium fiber that trap everything from big wood chips to tiny pollen particles. That activated carbon layer is a game changer for odors too - it actually absorbs smoke, pet smells, and musty odors so your home stays fresh. Each bag holds up to 8 quarts of dust and debris, meaning you won't have to change them as often. They're made with ABS plastic and quality materials that have been tested for tear resistance, so no worries about bags breaking and making a mess. When it's time to change, just remove the old bag, snap in a new one - super easy! Pro tip: change them when they're about 2/3 full to maintain good suction. At 24x6.1 inches, these are the exact same size as the original Oreck bags, so you know they'll fit perfectly. If you're tired of paying premium prices for brand name bags, these PETOX replacements work just as well for way less money!
