Formaldehyde (CH₂O), well known as a causative agent of sick building syndrome that causes respiratory diseases and atopy, is a class 1 carcinogen, also called methanal.

So, if we just avoid ‘new houses’, will we be safe from formaldehyde exposure? Not like that. If you feel an acrid smell or stinging eyes when you buy new clothes or furniture in your daily life, you are also exposed to the risk of formaldehyde.

Formaldehyde is a colorless gas pollutant that is known to be emitted from a variety of everyday products, such as furniture or wooden products with plywood or fiberboard, insulation, paint or wallpaper, polish, and cleaning products.

The size of formaldehyde particles is about 1/500 of 0.1 micrometer, making them very difficult to capture, but if not removed, gas emissions will continue, making long-term exposure unavoidable.

It is pointed out that we need to be more aware that it is not only a substance that causes symptoms of ‘sick building syndrome’, but also that it is a dangerous substance that commonly remains in our daily lives.

Accordingly, on the 12th, Dyson recommended that for a safe indoor environment, monitor various indoor pollution levels and operate a smart air purifier that automatically responds to remove various invisible and potentially harmful substances generated throughout daily life.

‘Dyson Big + Quiet Formaldehyde Air Purifier’, equipped with Dyson’s latest air purification technology, removes formaldehyde, fine dust (PM10), ultrafine dust (PM2.5), nitrogen dioxide (NO2), and volatile organic compounds (VOCs). It monitors, detects, and automatically responds to various air pollutants, temperature, and humidity levels to effectively purify indoor air quality.

Dyson’s unique selective catalytic oxidation filter continuously destroys formaldehyde. This catalytic filter is coated with a unique coating that has the same structure as the cryptomelane mineral.

The coating’s billions of atomic-scale tunnels are sized and shaped to capture formaldehyde and decompose and destroy it into trace amounts of water (H₂O) and carbon dioxide (CO₂). Since the catalyst coating is regenerated by oxygen in the air, it can be used continuously without replacement.

It also has a sealed filter system to meet HEPA H13 level, and the filter has been redesigned to be 3.8 times larger than the existing filter, effectively removing dust and allergens and removing 99.95% of particles as small as 0.1 microns. .

In addition to the existing sensor, a new sensor that detects carbon dioxide is installed to accurately report as soon as the carbon dioxide concentration exceeds the recommended amount.

It is designed to spray purified air over 10m by utilizing the cone-shaped aerodynamic phenomenon, and in addition to its powerful spraying power, it operates quietly, generating only 56dB of noise even at maximum wind speed.
