Keep your Dirt Devil CV1500 central vacuum running at full efficiency with this direct-fit secondary filter. Part number 4929 is the correct OEM-spec replacement -- no modifications, no guesswork. Degraded or clogged secondary filters rob your central vac of suction power and can allow fine particulates to pass through to the motor. Swapping in a fresh filter is one of the simplest, highest-impact maintenance steps you can perform on any central vacuum system.
The secondary filter in the CV1500 sits downstream of the primary dirt canister and upstream of the motor, acting as a final barrier against fine dust and debris before air reaches the internal components. Over time this filter loads up with ultrafine particles that restrict airflow, reduce suction at every inlet port in your rig or home, and place extra strain on the motor.
Dirt Devil part 4929 is the factory-specified replacement. At 8.5 x 6 inches it matches the original filter's footprint exactly, seating securely in the CV1500 filter housing without trimming or adapting. If your CV1500 has been running with reduced suction or the filter has visible discoloration or damage, this is the correct part to order.
Engineered specifically for the CV1500 housing. Drops in without modification for a reliable seal and full filtration coverage.
Measures 8.5 x 6 inches -- matching the original filter footprint and ensuring proper airflow restriction where it counts.
Acts as a final filtration barrier before air reaches the CV1500 motor, helping to extend motor life by blocking fine dust bypass.
Lightweight at under 0.1 lb. No tools required for filter access on the CV1500. A straightforward DIY maintenance task.
A restricted secondary filter is one of the most common causes of gradual suction loss in central vacuum systems. Unlike the primary dirt canister, secondary filters are often overlooked during routine cleaning. Most manufacturers recommend inspecting the secondary filter every 3 to 6 months and replacing it annually under normal use -- or sooner if you notice reduced suction, musty odors from outlets, or visible filter damage.
On the CV1500, the secondary filter is located between the dirt collection canister and the motor compartment. Refer to the parts diagram visible in the product photos for exact placement within the unit. The filter is accessed after removing the canister -- no special tools are required. Part 4929 is the only secondary filter listed for this unit; do not substitute with a generic cut-to-fit filter, as an improper seal will allow bypass.
