How to Clean a Built-in Vacuum Filter

A shop vacuum has the power to suck away the compacted dirt on the built-in vacuum's filter.

Built in or central vacuums are a series of sealed tubes that run from a central unit to outlets throughout a building. The central vacuum user is able to simply plug a hose into a wall outlet and begin vacuuming the room. With regular use a built in vacuum's filter can accumulate a thick layer of dust and make it difficult for the system to gain suction. Cleaning a central vacuum's filter allows air to flow though more easily and lowers the stress on the motor.

Things You'll Need

• Owner's manual
• Shop vacuum

Instructions

1. Consult the owner's manual for the specific model of built-in vacuum for information on caring for the filter. Even units with self-cleaning filters will need occasional manual cleanings to keep the units working their best. Some built-in vacuums are designed to use disposable paper filters while some others are filterless and use cyclonic action to separate debris from the air.

2. Remove the canister or bag at the base of the central vacuum unit. Most models have two or three latches that must be pulled out in order to take off the debris receptacle.

3. Turn on the shop vacuum and use the tip of the nozzle to gently brush the filter to release the dust so it can be sucked away. Do not tug on or attempt to remove the filter unless instructed to do so in the manual or under the supervision of a professional.

4. Empty any debris in the canister or bag before putting it back on below the filter and securing the latches.

Tips & Warnings

• Consult a professional central vacuum installer and service representative if the unit has any suction problems after the filter has been cleaned.

• Running a built-in vacuum with the filter removed or heavily clogged will damage the motor.
