A Must Have!


My husband and I have allergies, using a purifier fully sealed with HEPA filter, really makes us feel better. We love that it creates more indoor air circulation. Living in the west coast where some years affected by wildfire smoke, having a good purifier added a second layer of filtration aside from the house HVAC system.

Frequently asked questions

What is the Dyson Big+Quiet Formaldehyde air purifier range designed to do?​

Sources of formaldehyde can include woods, glues, paints, varnishes, air fresheners, mattresses, household cleaners, and some fabrics found in household flooring and furniture. The Dyson Formaldehyde air purifier range includes a catalytic filter that traps formaldehyde in tunnels, breaking it down into water and CO₂.⁵

How long do the Dyson Big+Quiet Formaldehyde filters last?

The Dyson Purifier Big+Quiet Formaldehyde has our largest ever filtration system. We recommend replacing the H13 grade HEPA filter after using it for up to five years or sooner. The activated carbon filter should be replaced every two years or sooner if required. The selective catalytic oxidisation filter is permanent and never needs replacing. ​

Where should I place the Dyson Purifier Big+Quiet Formaldehyde in my room?​

The Dyson Purifier Big+Quiet Formaldehyde has been designed to work from the corner of a room, at least three and a half feet away from the wall. For optimal performance we recommend projecting air either along a wall or across the room. You can adjust the angle of projection to suit your preference. ​

How easy is the Dyson Purifier Big+Quiet Formaldehyde to move?​

The Dyson Purifier Big+Quiet Formaldehyde has discreet wheels which are not visible when the product is upright. These wheels are designed for hard floors – so you can move your purifier around easily.
