Dyson HP04 Air Filter Systems: How It Purifies Air

The Dyson Hot + Cool HP04 air purifier uses two sets of filters that can remove up to 99% of harmful pollutants, according to the company.

The fully sealed 360-degree filtration unit is circular in design and consists of an activated carbon and HEPA filter to achieve removal of particulates and gas from the air.

The activated carbon filter comprises carbon granules impregnated with tris, which increase the adsorption power and ensure that the toxic gases are removed from the air even if they are present in trace amounts.

The glass HEPA filter has a pleated structure but is actually almost 9 meters of borosilicate fibers. These fibers are pleated over 238 times to improve the efficacy of trapping the smaller, ultrafine particles.

After passing through the two layers encased in a sealed chamber, the air filtered out is considerably cleaner. Finally, the powerful bladeless fan uses the air multiplier™ technology to distribute the purified air evenly.

The air purifier can oscillate between 45-degrees to 350-degrees to maintain this balanced flow of air.


Filter Change, Repairs, and Warranty
