For those constantly battling pollutants, wouldn\u2019t you want the best backpack vacuum cleaner to specifically target them? The HEPA Vacuum Cleaner is at your service. With its suction power and efficient sealing system, you can confidently suck up particles as small as 0.3 microns and make sure they stay captured.\r\n\r\nWhy We Like It - HEPA Vacuum Cleaner\r\nWith 180 CFM and efficient HEPA filtration system, the HEPA Vacuum Cleaner captures particles as small as 0.3 microns and keeps them captured inside a 2.5-gallon bin.\r\n\r\nPower\r\nJudging by its suction power of 180 CFM, yanking pet hair from tightly wound carpet isn\u2019t an issue to the HEPA Vacuums. This is made all the more apparent, considering it can suck in and capture particles as small as 0.3 microns.\r\nSpeed & Efficiency\r\nIts suction power, in combination with its HEPA filtration system, also improves the efficiency of the HEPA Canister Vacuums. Since it\u2019s so powerful, you\u2019ll rarely go over the same spot more than once. In fact, it seals the contaminants in, preventing them from exiting the upright vacuum and back into the air.\r\nBin Capacity & Maintenance\r\nMaintaining the HEPA Vacuum Cleaner is fairly simple: you dispose of the bags. What will require a small amount of work are the HEPA filters; they\u2019re reusable and just require a cleaning every so often to keep at peak performance. As for capacity, the vacuum bags are 2.5-gallon containers, which is one gallon more than the Koblenz Vacuum BP-1400.\r\nDurability\r\nEven the best HEPA vacuum cleaners have some plastic components, and this one isn\u2019t any different. However, that\u2019s only for a few attachments. As for the vacuum itself, it\u2019s primarily a metal composition, which really ups its sturdiness. This does come at the cost of being heavier; it\u2019s 23.3 lbs, so a 5-point harness system was added to help handle it. The Hoover Commercial C2401 is only 10 lbs.\r\nValue\r\nIf you\u2019re constantly plagued by pollutants in your workspace or even at home, the HEPA Vacuum Cleaner can already provide an invaluable service. It\u2019s built to snag those pollutants and, in turn, create a much friendlier and fresher environment than it was before. But remember this: it uses vacuum bags, so if cost effectiveness is what you\u2019re after, then the ProTeam ProVac FS6 is available.\r\nHEPA Vacuum Cleaner Wrap Up\r\nThe HEPA Vacuum Cleaner has very few flaws. It\u2019s heavy (23.3 lbs), but its 5-point harness system largely circumvents that. And with vacuum bags, the plus here is that pollutants stay in the bag, rather than get sucked out another end. After all, it can capture particles as small as 0.3 microns. Its cloth filter is also reusable.
