Dyson HP00 Air Purifier captures ultrafine dust and allergens. Quite compact, it differs from its brothers in size since it is only 63 cm high. It can therefore be placed on the floor as easily as on furniture. It automatically detects particles and gaseous pollutants in the air, then analyzes and reports on air quality in real time. This allows you to monitor the air quality on the LCD screen. The hermetic filtration system combines an activated carbon filter to absorb gases and a fiberglass HEPA filter that captures 99.95% of microscopic particles as small as 0.1 micron. Thanks to the long-range projection, it is easy to heat an entire room evenly. Likewise, when it's hot, its powerful flow of purified air allows you to cool off. Ambient mode projects the airflow to the back of the device. To purify, without cooling off while night mode monitors and purifies the air using its quietest settings and reducing the brightness of the display.
