What does the HEPA H13-grade filter capture?

The HEPA H13-grade filter captures 99.95% of particles as small as 0.1 microns.¹ It helps capture allergens and other ultra-fine airborne particles, while the activated carbon layer helps remove odours and gases, including Volatile Organic Compounds (VOCs). This combination supports effective air filtration in compatible Dyson purifiers.

¹ Tested for filtration efficiency at 0.1 microns. Gas capture rates may vary.

What is the benefit of the activated carbon layer in this filter?

The activated carbon layer helps remove odours and gases, including Volatile Organic Compounds (VOCs).² Working alongside the HEPA H13-grade filter, it helps capture pollutants from the air passing through your Dyson purifier. This combination enables the filter to address both airborne particles and unwanted odours.

² Gas capture rates vary.

When should I replace my Dyson purifier filter?

Replace your Dyson purifier filter when your machine alerts you. Dyson also recommends replacing the filter every 12 months.

Over time, microscopic pollutants can clog the filter, affecting how effectively it works and potentially allowing unpleasant odours back into the room. Replacement timing can vary with use, so follow your machine’s filter indicator rather than relying on appearance alone.

Can this filter help reduce allergens and airborne particles in my home?

How do I know when my Dyson purifier filter needs replacing?

Your Dyson purifier will alert you when its filter needs replacing. This is the clearest sign that it’s time to fit a new one. 

Filters gradually become clogged with microscopic pollutants and may allow unpleasant odours back into the room. Follow the alert, then reset the filter indicator after installing the replacement according to your machine’s operating manual. Always unplug the machine before changing its filter.
