Frequently Asked Questions
Why does my Dyson vacuum lose suction?

How often should I replace the filters?
Filters should be cleaned every 1-3 months and replaced every 6-12 months depending on usage. Using compatible filters like the 3Pack Pre Filters or V10 Filters helps maintain suction.
Can I wash the filters?
Yes, most Dyson filters are washable. Rinse them with water, let them dry completely for at least 24 hours, and then reinstall. Do not use detergents or hot water.
