Frequently asked questions

How often does the filter in this machine need changing?

The filter has been designed to last a full year; this is based on 12 hours' daily use. However, the filter may need replacing sooner depending on environmental conditions (e.g. if any smoke is pulled through the machine). You can find a replacement filter here.

Is my purifier filter covered by the Dyson warranty?

Yes. Your Dyson purifier filter is guaranteed against original defects in materials and workmanship for a period of 12 months from the date of purchase. Filter units that must be replaced because the filter life has expired are not covered by the warranty.
