Dyson Humidify + Cool Formaldehyde PH04

Not only the filter, but the whole unit meets the HEPA-13 standard. What gets into the unit stays there. The air purifiers have special sensors to detect formaldehyde molecules 500 times smaller than 0.1 micron.
Dry air can lead to dehydration. The Dyson humidifier with air purification function automatically maintains the correct humidity level in the room air. For a more comfortable environment all year round.
The Dyson Purifier Humidify+Cool features a sealed 360˚ filtration system. It combines an activated carbon filter to remove gases and odours and a sealed HEPA filter to remove 99.95% of ultra-fine particles.
Dyson Ultraviolet Cleanse technology exposes every drop of water to an ultraviolet light. This removes 99.9% of bacteria in the water. An efficient water management system and 5-litre water tank provide continuous humidification without the need for regular refills. Air Multiplier technology distributes up to 350 litres of cooling air 5 per second. The air is mixed and distributed throughout the room so you don't breathe in dry, stale air. Choose between fan mode, breeze mode to mimic a cooling, refreshing breeze and in the winter months you can use the distribution function to clean and humidify the air - without direct frontal airflow.
