Hepa-Flow High Efficiency Filter Bags (NVM-1CH, 604015) (pack of
10) - fits most of
the Henry series of vacuums from Numatic/NaceCare (ie, canister
sizes 160, 170, 180, 200, 240, 250 and 300). These are genuine
(not aftermarket) bags and should be used to contain extracted
dust and debris and to protect the motor from damage. Plastic
flap seals the bag and contents at disposal. Great value at
$2.50/bag which is why I only offer the 10pc packaging.
The bags are made from three layers of
spun polypropylene and no fiberglass is used. HepaFlow filter
bags will filter particles down to 0.3 microns in size. Bag
capacity is 9 liters...same bag is used for the 160 size canister
all the way up to the 300 canister.
All Henry series vacs also have a
standard Tritex drum top filter to further protect the motor and
the HEPA certified machines (like the NVR170H) have an H13 HEPA
filter element right at the motor.
