Air-purifier HEPA filters: check whether they can be washed before cleaning

Many HEPA and carbon filters are non-washable. Identify the prefilter, check filter-life indicators and use the correct replacement.

Not every dusty part of an air cleaner can be rinsed. Dyson support identifies several HEPA/carbon filters as non-washable and provides model-specific replacement alerts and reset instructions. Filter lives vary widely by machine and usage; avoid assuming a universal annual replacement interval.

Your try-it-at-home checklist

0 / 6 done

Find the model number and distinguish the prefilter, HEPA filter and carbon filter using the manufacturer manual.
Switch off and unplug the purifier. Remove dust from the intake grille with only an approved soft brush or dry cloth.
Never soak, spray or detergent-clean HEPA/carbon media marked non-washable; replace with the specified part when damaged or prompted.
Rinse a prefilter only if its own manual permits washing, and let it dry fully before reinstalling; never transfer that instruction to the HEPA medium.
Remove packaging from the new filter, fit it in the correct orientation and check that its housing securely closes.
Reset the filter-life counter exactly as instructed for that model and record the replacement date. Seek service if problems persist.
