How to Get Rid of a Musty Smell in a Dyson Vacuum Cleaner

Updated February 21, 2017

Dyson vacuum cleaners provide a bagless canister which you empty after each cleaning session. Over time the canister and HEPA filter may develop a musty smell. As you sweep, the vacuum can distribute the musty odour throughout the house. To remove the smell, the removable canister and HEPA filter need to be cleaned. Normally, Dyson vacuums contain a lifetime HEPA filter, which can be cleaned instead of replaced. Cleaning the canister involves removing it from the vacuum.

  1. Release the canister from the Dyson vacuum cleaner by pushing the button at the top of the handle attached to the canister. Remove the canister from the vacuum. Hold the canister over the top of a dustbin.

  2. Push the button at the top of the canister to release the bottom lid. Knock the canister gently against the side of the dustbin to dislodge dirt and dust.

  3. Fill a bucket with warm water and 1 tsp liquid dish soap. Wet a sponge with the soapy mixture. Wipe the inside of the canister with the sponge. Rinse the sponge in the bucket as you continue to remove dirt from the canister.

  4. Rinse the canister with clean water and the sponge. Remove all soapy residue. Dry the canister completely with a towel.

  5. Remove the HEPA filter. The HEPA filter is located below the canister, so remove the canister first. Pop the lid covering the HEPA filter. You may need a flathead screwdriver to push under the lip of the lid to pop it off. Remove the filter and place in a sink. Run cool water through the filter for two minutes. Wrap the filter in an old towel and allow it to dry overnight.

  6. Place the filter back into the vacuum when it has dried completely. Pop the lid over the filter and replace the canister on the vacuum.
