The current Dyson Hot + Cool purifying fan isn’t a particularly noisy appliance, but it does tend to whistle at the most powerful fan settings. The other big upgrade Dyson is pushing its “whole-machine HEPA filtration” design. While previous generations (and competing purifiers) use medical-grade HEPA filters to destroy pollutants and allergens that pass through them, there are still opportunities for nasty particles to slip through the cracks. With its new range of air purifier fans, Dyson implemented high-pressure seals in 24 areas where pollutants have otherwise had the opportunity to slip through in the past. The result is an entire machine that meets HEPA H13 standards, rather than just the filter itself. The new Dyson Purifier Hot + Cool Formaldehyde model will cost $999, while the Dyson HEPA Cool Formaldehyde model cost $799. Both models will be sold in white and gold variants. Short term exposure to formaldehyde levels exceeding 0.1ppm can cause watery eyes, coughing, nausea and more but formaldehyde is also classified as carcinogenic, as there’s evidence to suggest that long-term exposure has been linked to cancer cases.
