Introduction

Use this guide to remove, wash, dry, and reinstall the filter in a Dyson V12 vacuum. A dirty filter can restrict airflow and reduce suction. The video demonstrates an older tissue-and-brush method; the written steps below follow Dyson's current V12 washing guidance. Wash the filter monthly, or more often after vacuuming fine dust or using Boost mode frequently. The filter must be completely dry before reinstallation.

What you need

Step 1 Remove the filter

Turn off the Dyson V12 and disconnect it from the charger.
Turn the filter counterclockwise and gently pull it away from the vacuum.
Keep water away from the vacuum body, motor area, battery, and charging contacts.
Do not run or charge the vacuum while the filter is removed or wet.

Step 2 Remove loose debris

Gently tap the filter over a trash bin to remove loose dust and debris before washing it.
Inspect the filter media, housing, and seal for tears, cracks, or deformation.
Do not use tissue or a brush to scrub the pleated filter media.

Step 3 Wash the pleated element

Hold the filter under warm running tap water with the foam element facing down.
Run warm water over the pleated paper element until the water runs clear.
Do not use detergent, hot water, a dishwasher, or a washing machine.
Do not scrub the pleated paper element with a brush.

Ask FixBot

Step 4 Wash the foam element

Keep the foam element facing down so dirty water cannot contaminate the pleated paper.
Run warm water over the inside and outside of the foam element, and gently squeeze the foam to expel dirt.
Wash the outside of the filter, fill it with warm water, cover the openings with your hands, and shake it gently.
Repeat the wash until the water runs clear.
Gently shake out excess water and leave the filter to drain with the foam element facing up.

Step 5 Dry the filter

Leave the filter in a dry area with good airflow for at least 24 hours.
The filter must be completely dry before reinstallation.
Do not use a tumble dryer, oven, microwave, heater, or open flame to speed drying.
If the filter still feels damp after 24 hours, let it dry longer.

Step 6 Reinstall the filter

Insert the completely dry filter into the vacuum.
Turn the filter clockwise until it clicks into place.
Run the vacuum briefly and check that airflow and suction have improved.

Step 7 Maintain or replace the filter

Wash the filter once a month to help maintain suction.
Wash it more often after vacuuming fine dust or using Boost mode frequently.
Replace the filter if it is damaged, worn, or cleaning no longer restores performance.
Use a replacement that is compatible with Dyson V12 vacuums.

Conclusion

After the completely dry filter is locked in place, run the vacuum briefly and check that airflow has improved. If the problem continues, ask the Dyson V12 Answers community for help.
