Dyson Humidifier Fan Review
Dyson Pure Humidify + Cool PH01 Renewed
ADVANTAGES
LIMITATIONS
This renewed powerhouse delivers flagship air treatment without the premium price tag, making it a game-changer for budget-conscious buyers who refuse to compromise on health-tech performance. With HEPA filtration capturing 99.97% of allergens down to 0.3 microns, real-time sensing of particles and humidity, and UV Cleanse technology obliterating 99.9% of bacteria in water, it tackles two of indoor air’s biggest threats: dryness and contamination. Its Air Multiplier system ensures purified, invisible vapor spreads evenly—no misty residue or stagnant zones—ideal for allergy sufferers and those in arid climates craving consistent comfort.
In daily use, the PH01 proves its mettle across seasons: it cools efficiently in summer with smooth, wide airflow and maintains stable humidity in winter, preventing dry skin and respiratory irritation. The one-gallon tank lasts up to 36 hours, minimizing refills, while the smart sensors automatically adjust output when pollutants spike or humidity dips. However, it lacks the De-NOx capability of newer models and doesn’t destroy formaldehyde continuously—limiting its edge in urban homes with high traffic pollution. The LCD interface is functional but not as intuitive as the app-driven PH03.
Compared to the newer PH2 and PH03, the PH01 sits as the smart entry point for performance purists who want proven Dyson engineering at a reduced cost. It’s nearly identical in function to the PH03 but misses out on app integration and advanced scheduling. Still, for those prioritizing hygienic humidification and core purification over bells and whistles, this renewed model offers unmatched value—delivering 90% of the top-tier experience at less than half the price of the PH2.
Dyson Purifier Humidify+Cool PH2 De-NOx
ADVANTAGES
LIMITATIONS
Meet the apex predator of indoor air quality—a triple-threat machine engineered to dominate pollutants most purifiers ignore. The PH2 isn’t just another humidifier fan; it’s a precision weapon against NO₂ and formaldehyde, capturing 50% more nitrogen dioxide than prior models and continuously breaking down formaldehyde into harmless water and CO₂. Backed by a fully sealed HEPA H13 filter that traps 99.97% of ultrafine particles, and UV Cleanse technology that eradicates 99.9% of bacteria in the water tank, this unit redefines what clean air means in high-pollution environments.
Real-world testing reveals its raw power and intelligence: the Air Multiplier blasts 77 gallons of air per second, creating a cooling effect that rivals standalone fans, while the 350° oscillation blankets entire rooms in purified airflow. Whether you’re battling city smog, pet odors, or seasonal dryness, the PH2 adapts instantly, with MyDyson app integration offering remote control, voice commands, and personalized air reports. However, its massive feature set comes with complexity—the app can feel overwhelming, and the unit’s tall profile demands floor space. Also, humidification output can lag in very large rooms during peak winter.
Against the PH03 and PH01, the PH2 is the unquestionable upgrade for urban dwellers and chemical sensitivity sufferers, trading portability and simplicity for military-grade purification. While it shares core DNA with the PH03, it leaps ahead in gas removal and automation, making it ideal for homes near busy roads or with new furniture off-gassing VOCs. It’s the most complete air treatment system Dyson has ever built, justifying its premium status with performance no other model matches.
Dyson Purifier Humidify+Cool PH03
ADVANTAGES
LIMITATIONS
The PH03 strikes a masterful balance—a trifecta of purification, humidification, and cooling wrapped in Dyson’s signature elegance and intelligence. This isn’t just a fan that adds moisture; it’s a whole-room climate guardian that senses pollution, adjusts output, and keeps your air consistently fresh, cool, and bacteria-free. With HEPA H13-grade sealing, UV Cleanse technology, and a one-gallon tank delivering up to 36 hours of runtime, it excels in both performance and convenience, especially for users who hate constant maintenance.
In practice, the PH03 adapts seamlessly to your life: Breeze mode mimics natural wind for a soothing effect, while Backward airflow mode quietly purifies and humidifies without cooling—perfect for nighttime. The LCD screen and MyDyson app provide real-time pollution tracking, and filter-life alerts take the guesswork out of maintenance. It handles medium to large rooms with ease, though in very dry climates, it may struggle to maintain ideal humidity above 50% without frequent top-ups. Unlike the PH2, it doesn’t destroy formaldehyde, a notable gap for homes with new builds or furnishings.
Positioned between the renewed PH01 and high-end PH2, the PH03 is the sweet spot for most households—offering smart features, strong purification, and long runtime without the steep cost of De-NOx tech. It’s more capable than the PH01 and more user-friendly than the PH2, making it the best all-around choice for families, allergy sufferers, and tech-savvy users. It delivers exceptional breadth of function at a price that reflects value, not excess.
How to Choose the Right Dyson Humidifier Fan
Core Functionality: Purification, Humidification, and Cooling
Dyson humidifier fans offer a triple threat: air purification, humidification, and cooling. When choosing, consider which of these is most important to you. If allergies are a major concern, prioritize models with advanced filtration (like the PH2 De-NOx) that specifically target pollutants like NO₂ and formaldehyde. If dry air is your primary issue, focus on models with larger water tanks (up to 36 hours of run time in some models) to minimize refills. And if you live in a warmer climate, the cooling fan function, enhanced by Air Multiplier technology, will be a significant benefit. Understanding your priority will narrow down your options considerably.
Filtration & Air Purification
The quality of the filtration system is a key differentiator. All Dyson humidifier fans boast HEPA H13 filtration, capturing 99.97% of particles as small as 0.3 microns. However, some models, like the PH2 De-NOx, go further with advanced purification capabilities, specifically targeting and removing more NO₂ – a common indoor pollutant. Consider your local air quality and potential pollutant concerns. Features like sealed filtration systems are also crucial, ensuring that captured pollutants stay inside the machine and aren’t recirculated.
Humidification Technology & Maintenance
Dyson humidifier fans utilize hygienic humidification, often incorporating Ultraviolet Cleanse technology to eliminate bacteria in the water. This is a significant benefit compared to traditional humidifiers that can harbor mold and bacteria. Maintenance is another key consideration. Look for models with hassle-free deep clean cycles and easily replaceable filters with built-in notifications via the MyDyson app, alerting you when maintenance is required. This will save you time and ensure optimal performance.
Smart Features & Control
Many Dyson humidifier fans offer smart features like app control (MyDyson app) and voice assistant compatibility (Amazon Alexa, Apple Siri, and Google Home). These features allow for remote control, scheduling, real-time air quality monitoring, and personalized reports. While not essential, these can add convenience and a deeper understanding of your indoor air quality. The ability to set schedules and receive air quality reports can be particularly valuable for those with sensitivities or concerns about specific pollutants.
Airflow & Coverage Area
Dyson’s Air Multiplier technology is central to these machines’ effectiveness. It projects a powerful, yet smooth, airflow to circulate purified and humidified air throughout the room. Consider the coverage area of the model relative to the size of your room. Some models offer oscillation (up to 350°) to distribute airflow more evenly.
