Dyson Purifier Humidify+Cool PH3A (White)

What room size is the PH3A suitable for?

The PH3A effectively covers rooms up to 27 square metres. This makes it suitable for most bedrooms, living rooms and open-plan areas. The 360-degree air intake and powerful projection ensure even air treatment throughout the entire space, reaching corners and creating uniform air quality.

How often do I need to refill the water tank?

The 5.2-gallon water tank provides up to 16 hours of continuous humidification. Refill frequency depends on humidity settings and room conditions, but typically requires refilling every 1-2 days with regular use. The unit automatically shuts off when water levels are low to prevent damage.

Is the PH3A suitable for people with allergies?

Yes, the PH3A is British Allergy Foundation approved. The HEPA H13 filter captures 99.95% of particles as small as 0.1 microns, including common allergens like pollen, dust mites and pet dander. The sealed filtration system prevents contaminated air from bypassing the filter, providing reliable allergy relief.

How loud is the unit during operation?

The PH3A operates at just 62 decibels on maximum speed, which is quieter than normal conversation. Lower speed settings are even quieter, making it suitable for bedrooms and study areas. The advanced acoustic engineering minimises motor noise whilst maintaining effective air circulation.

What maintenance does the PH3A require?

Regular maintenance includes refilling the water tank and replacing the HEPA filter when indicated. The unit features automatic alerts for filter replacement. Clean the water tank weekly with mild detergent to prevent bacterial growth. The exterior can be wiped clean with a damp cloth.

Can I control the humidity level?

The PH3A automatically maintains optimal humidity levels based on environmental conditions. It monitors air quality and adjusts humidification accordingly. The 10 speed settings allow you to influence humidity output, with higher speeds providing more moisture to the air when needed.

Does it work as an effective air cooler?

The cooling function provides personal cooling through evaporative technology and airflow projection. Whilst not a replacement for air conditioning, it creates a cooling breeze that can reduce perceived temperature by several degrees. The cooling effect is most noticeable when positioned near seating areas.
