Can I put a washed vacuum filter straight back in?
Not for the Dyson filters covered by the cited care instructions. Dyson requires complete drying before refitting and specifies at least 24 hours for those filters. Check the exact filter’s instructions; not every filter is washable. [1]
Plan the drying time before washing. Do not treat “looks dry” as a substitute for the manufacturer’s instructions, and do not transfer this method to a different filter without checking. [1]

Does 24 hours guarantee the filter is dry?
No. Dyson requires it to be completely dry and advises a physical moisture check before reinstallation; the time alone is not the only condition. [1]
Can I wash a cordless vacuum filter and reinstall it immediately?
Not for the Dyson filters covered by the cited instructions: they require complete drying, with at least 24 hours specified. Other filters may have different care rules, so identify the exact filter before washing it. [1]
