The Dyson Humidify+ Cool PH2 De-NOx, a multi-functional device that acts as an air purifier, humidifier, and fan, is now available for 599 euros, a reduction from its original price of 799 euros, according to a recent report. Designed for use throughout the year, the device features a bladeless design, which enhances safety and makes it easier to clean. It includes advanced HEPA H13 and K-Carbon filters that are specifically engineered to target nitrogen dioxide (NO2) and capture ultrafine particles as small as 0.1 microns. Dyson claims the device can filter out 99.95% of airborne particles and up to 50% of NO2 compared to standard activated carbon filters, making it a strong option for improving indoor air quality. The device is equipped with a 5-liter water tank, which, according to the manufacturer, can provide up to 36 hours of continuous humidification on the lowest speed setting. Users can control the device using a magnetic remote, an LCD screen, and a mobile app called MyDyson. Through the app, users can select from ten different ventilation levels, set automatic operation modes, and monitor the air quality in real time. The device stands 92.3 centimeters tall, has a diameter of 31.2 centimeters, and weighs 8.12 kilograms. It features a limited 90-degree oscillation and operates at noise levels ranging from 46 decibels (similar to a quiet room) to 62.4 decibels (comparable to a normal conversation). Dyson recommends that users clean the water circuit once a month and replace the HEPA/K-Carbon filter annually, assuming the device is used for 12 hours each day. While the device is designed to complement proper ventilation, it is not intended to replace it entirely. The Humidify+ Cool PH2 De-NOx represents a blend of advanced technology and user-friendly design, aiming to provide a comprehensive solution for managing indoor air quality in homes and offices.
