Best Dyson Humidifier Review
Dyson Pure Humidify + Cool PH01 Renewed
ADVANTAGES
LIMITATIONS
This renewed powerhouse delivers flagship air care at a fraction of the cost, making it the ultimate entry point into Dyson’s premium ecosystem. With HEPA filtration, UV Cleanse technology, and Air Multiplier airflow, it tackles dry air, allergens, and pollutants in one sleek unit—perfect for urban dwellers battling seasonal allergies or winter dryness. It automatically senses humidity and pollutants, adjusting output to maintain a balanced indoor climate, turning your bedroom or office into a sanctuary of clean, comfortable air.
In real-world use, the PH01 shines in medium to large rooms, circulating purified, microbe-free vapor across 300+ sq. ft with near-silent operation on low. The one-gallon tank offers up to 36 hours of runtime, and the UV Cleanse system ensures bacteria like Legionella are neutralized before mist dispersal—no more worrying about dirty humidifiers. However, it lacks the PH2’s De-NOx filtration and formaldehyde destruction, and the app integration is more basic than newer models, limiting remote customization.
Compared to the newer PH03 and PH2, the PH01 sits as the budget-savvy sibling—offering 90% of the functionality at half the price, especially in renewed form. It’s ideal for renters, students, or anyone prioritizing air quality value over bleeding-edge gas filtration. While it doesn’t destroy formaldehyde or capture NO₂ like the PH2, it still outperforms standalone humidifiers and most mid-tier purifiers—making it the smartest pick for cost-conscious buyers who refuse to compromise on hygiene and build quality.
Dyson Purifier Humidify+Cool PH2 De-NOx
ADVANTAGES
LIMITATIONS
Meet the undisputed king of air treatment—a tri-functional marvel that redefines what a home air system can do. The PH2 doesn’t just humidify and cool; it destroys formaldehyde, captures ultrafine NO₂ particles, and uses HEPA H13-grade sealed filtration to eliminate 99.97% of pollutants down to 0.3 microns. With Dyson’s most advanced sensor suite, it detects volatile organic compounds, humidity, and temperature in real time, then adapts silently—making it a must-have for allergy sufferers and city dwellers exposed to traffic pollution.
During testing, the PH2 handled everything from winter dryness to summer heat with laser-precise responsiveness. The 77 gallons-per-second airflow delivers a cooling blast without the harshness of traditional fans, while the 350° oscillation ensures even distribution in large living spaces. Its formaldehyde-destroying catalyst continuously breaks down this common off-gassing chemical from furniture and carpets—a feature no other humidifier offers. The only hiccup? The tank requires weekly deep cleaning, and the filters are costly over time, though necessary for peak performance.
Against the PH03, the PH2 is the clear upgrade—especially for homes near high-traffic areas where nitrogen dioxide is a concern. It’s overkill for small apartments but perfect for health-focused families or those with respiratory sensitivities. While the PH03 offers great value, the PH2 justifies its premium with next-gen gas filtration and smarter automation—making it the most complete air solution Dyson has ever built.
Dyson Purifier Humidify+Cool PH03
ADVANTAGES
LIMITATIONS
The PH03 strikes a masterful balance between innovation and usability, emerging as Dyson’s sweet spot for high-end air care without the extreme premium. It intelligently blends purification, humidification, and cooling with a fully sealed HEPA H13 system—ensuring zero leakage of captured pollutants—while the one-gallon tank delivers 36 hours of hygienic moisture, ideal for all-night comfort in dry climates. Its LCD dashboard and MyDyson app integration provide crystal-clear feedback on air quality, making invisible threats feel tangible and manageable.
In daily use, the PH03 adapts like a seasoned butler—ramping up during cooking fumes, quieting at bedtime, and switching to Backward Airflow mode to purify without chilling you. The 90° oscillation in Fan mode offers targeted cooling, while Breeze mode mimics natural wind patterns for subtle relief. UV Cleanse neutralizes bacteria in the water tank, and filter-life alerts prevent maintenance neglect—a godsend for busy households. It doesn’t match the PH2’s De-NOx prowess, but for most users, the difference in real-world air quality is marginal.
Positioned between the budget PH01 and elite PH2, the PH03 is the best all-rounder for discerning homeowners who want top-tier performance without overspending. It’s more future-proof than the PH01 and more practical than the PH2 for average homes. While it lacks the PH2’s formaldehyde destruction, it offers 95% of the benefits at a significantly better value, making it the ideal flagship for holistic, hands-off air wellness.
Choosing the Right Dyson Humidifier
Core Features to Consider
When selecting a Dyson humidifier, several key features will significantly impact your experience. Focusing on these will help you find the best model for your needs.
1. Purification Capabilities: Dyson humidifiers aren’t just humidifiers; they’re air purifiers first. Consider the level of purification you require. Models like the PH2 De-NOx boast advanced filtration that captures a higher percentage of pollutants like NO₂ and formaldehyde. If you live in an area with poor air quality or have allergies, prioritize a model with HEPA H13 filtration and activated carbon filters. A fully sealed filtration system (like in the PH03) is crucial to ensure pollutants aren’t recirculated.
2. Humidification Capacity & Tank Size: The size of the water tank directly affects how often you’ll need to refill it. Models with larger tanks (like the PH03’s one-gallon tank) offer longer run times – up to 36 hours – reducing maintenance. Also consider the room size. Larger rooms will benefit from higher humidification output. While all Dyson humidifiers aim for whole-room humidification, a larger tank and more powerful projection are essential for expansive spaces.
3. Smart Features & Connectivity: Dyson’s MyDyson app provides remote control, real-time air quality reporting, and personalized insights. Features like scheduling and voice control compatibility (Amazon Alexa, Apple Siri, Google Home) add convenience. The PH03 and PH2 both offer these features, allowing you to monitor and adjust settings from anywhere.
Other Important Features
- Air Multiplier Technology: All models utilize this technology for effective air circulation, distributing purified and humidified air evenly.
- Oscillation: Models offer varying degrees of oscillation (e.g., 350° on the PH2, 90° on the PH03) to direct airflow around the room.
- Maintenance & Filter Replacement: Look for models with easy-to-replace filters and automatic notifications when maintenance is required.
- Specialized Technologies: Some models (like the PH01) utilize Ultraviolet Cleanse technology to eliminate bacteria in the water.
- Refurbished Options: Dyson Renewed models (like the PH01) offer a budget-friendly entry point, but be aware of potential cosmetic imperfections. These are still rigorously tested and perform to Dyson’s standards.
- Cooling Function: Some models (PH2, PH03) also function as fans, providing cooling in warmer months.
