Do I have to change my filter?

We recommend changing your filter every six months, or whenever you change your battery. Filters can become blocked over time, negatively affecting the suction power, air flow and overall performance of your vacuum cleaner. It’s important to replace the filter regularly to ensure your Dyson vacuum is always performing optimally.

Will this fit my vacuum cleaner?

This battery is compatible with Dyson DC31, DC34, DC35, DC44 and DC45 models, Type B ONLY. Please note, we also sell the Type A version of this battery. To identify the correct replacement battery, check the one that is currently in your vacuum cleaner. The Type B version has to be removed with a screwdriver, and a sticker on the bottom of the battery will generally confirm the model you have.

If you are not sure which battery you need, our technical advice team will be happy to help.

What if I see it cheaper somewhere else?

We always recommend buying a high-quality battery from a reputable seller. Batteries being sold cheaper elsewhere on the internet may not have undergone the appropriate rigorous safety tests and are often sold with fake warranties. All our batteries are CE tested and approved to ensure the highest standards of safety and performance, and come with the same 1-year warranty offered by Dyson.
