NaceCare NVM-4BH HepaFlo Bags for Dry Pickup on the WV 900


The WV 900 is a 12-gallon wet vac first, but it vacuums dry debris well too, as long as it's set up for it. NaceCare's manual calls for an NVM-4BH bag and the primary filter whenever you pick up dry dirt, and this is that bag.

Each HepaFlo bag has three layers of filter media and a self-seal tab, so a tank-sized load of dust comes out sealed. A pack holds 10 bags.


The Owner's Insights on Running a WV 900 Dry

Dry dust without a bag goes straight to the filter and coats it in minutes, and suction falls off fast. With a bag in, the filter stays clean and the dust comes out in one sealed package instead of a tank you have to tip into a dumpster.

Before you switch back to water, take the bag out. A wet bag tears, and it can block the float that shuts the vacuum off when the tank is full.


Which Vacuums Take NVM-4BH Bags?

Pair it with the 14-inch primary filter 604116 for dry work. The CV 570 and the WV 1800 series don't use this bag. Need 10 or more packs? Call (855) 601-5678 for a volume quote.
