Filtration Technology
The PH01 uses a sealed True HEPA filter that captures 99.97% of particles as small as 0.3 microns, including pollen, dust mites, mold spores, and fine pet dander. An activated carbon layer absorbs gases, VOCs, smoke, and household odors , a meaningful addition that many entry-level purifiers skip.
The UV-C light component works specifically on the humidification side, killing 99.9% of waterborne bacteria before moisture is released into the air, which sets it apart from standard humidifier-purifier combos that can inadvertently spread contaminants.
Noise & Performance
Dyson rates the PH01 for whole-room coverage, though specific CADR numbers are not published in the traditional sense , Dyson uses its own airflow projection metrics instead. The machine uses Air Multiplier technology to project purified air across the room rather than relying on a single directional stream.
Noise levels tend to be moderate at lower fan speeds, making it workable for living rooms and offices, though light sleepers may find even the lowest setting noticeable in a quiet bedroom.
Smart Features & Controls
The PH01 features manual controls and an auto mode powered by a built-in air quality sensor that senses particulate levels in real time and adjusts fan speed accordingly. An air quality indicator on the LCD display provides a visual readout of current conditions, which is helpful for understanding when the machine is working hardest.
However, the notable gap here is the absence of WiFi , unlike newer Dyson models, this unit cannot be controlled via the Dyson Link app or integrated with Alexa or Google Home.
Filter Maintenance
Dyson recommends replacing the combined HEPA and carbon filter approximately every 12 months depending on usage and air quality conditions. The machine includes a filter change indicator that alerts you when replacement is due, removing the guesswork.
The humidifier component requires periodic deep cleaning cycles , Dyson's built-in deep clean cycle guides you through descaling the water system, which is straightforward but does require attention to maintain hygienic operation.
Who Is This Air Purifier For?
Ideal For
- ✓ Allergy and asthma sufferers , True HEPA filtration captures pollen, dust mites, and pet dander at 99.97% efficiency, while auto mode reacts to rising allergen levels
- ✓ Pet owners dealing with dander and odors , the carbon filter neutralizes pet smells while HEPA captures fine dander particles
- ✓ People in dry climates or heated homes , the built-in humidifier with UV-C sanitation adds clean moisture without a separate machine
- ✓ practical buyers who want Dyson quality , the Renewed tier makes this premium 3-in-1 machine significantly more accessible
Not Ideal For
- ✕ Smart home enthusiasts , no WiFi connectivity means no app control, voice assistant integration, or remote monitoring of air quality
- ✕ Light sleepers needing whisper-quiet bedroom operation , the PH01 may produce noticeable noise at lower speeds due to the combined purifier-humidifier motor
- ✕ Buyers who want a brand-new, flawless unit , Renewed products meet functional standards but may show cosmetic imperfections
Setup is minimal , remove the outer shroud, install the sealed HEPA/carbon filter, snap the shroud back on, fill the water tank, and power on. The machine is ready to purify immediately, though the humidifier may need an initial deep clean cycle before first use.
Run the first deep clean cycle before using the humidifier function to flush the internal water system
Place the unit at least a foot from walls to allow unobstructed 360-degree air intake
As a Renewed product, warranty coverage differs from new Dyson purchases , check the specific seller listing for the included warranty period, which typically ranges from 90 days to 1 year. Dyson's standard customer support can assist with troubleshooting, though official Dyson warranty terms may not apply to Renewed units.
FAQ
Does the Dyson PH01 Renewed work as well as a brand-new unit?
Renewed machines are tested and certified to meet Dyson's functional standards, so filtration and humidification performance should be identical to new. The main differences are cosmetic , expect possible light scratches or minor imperfections on the exterior that don't affect how the machine operates.
Can I use the Dyson PH01 as just an air purifier without the humidifier?
Yes, the purification and humidification functions operate independently. You can run it in purifier-only mode year-round and only activate the humidifier during dry months.
The True HEPA and carbon filtration works continuously regardless of the humidifier setting.
How often do I need to replace the filters on the Dyson PH01?
Dyson recommends filter replacement approximately every 12 months, though this varies with usage and local air quality. The machine has a built-in filter life indicator that tracks usage and alerts you when it's time.
Replacement filters are available directly from Dyson and third-party sellers.
Is the Dyson PH01 quiet enough for a bedroom?
At lower fan speeds the PH01 produces moderate noise, but it may be noticeable for light sleepers in a quiet bedroom. The auto mode can ramp up fan speed if it senses declining air quality overnight, which could cause intermittent noise spikes.
For the quietest bedroom operation, running it on a low fixed speed rather than auto mode is recommended.
Does the Dyson PH01 connect to WiFi or work with Alexa?
No, the PH01 does not have WiFi connectivity and cannot be controlled through the Dyson app, Alexa, or Google Home. All controls are managed directly on the machine or via the included remote.
If smart home integration is essential, consider newer Dyson models with built-in WiFi.
What does the UV-C light do in the Dyson PH01?
The UV-C light is specifically used to sanitize water in the humidifier tank before it's dispersed into the air. It kills 99.9% of bacteria in the water, ensuring the moisture added to your room is hygienic.
This is a key differentiator from standard machines that can spread waterborne contaminants through untreated mist.

Bottom Line
The Dyson PH01 Renewed is an excellent value proposition for anyone who needs both purification and humidification without buying separate machines. Its True HEPA filtration, carbon odor removal, and UV-C sanitized humidification deliver genuinely useful performance for allergy sufferers and pet owners in dry environments.
However, the lack of WiFi and smart features feels dated, and this unit is best suited for buyers who prioritize air quality performance over connected convenience.
Best for allergy-prone households in dry climates who want Dyson's 3-in-1 purifier-humidifier-fan at a reduced Renewed tier
Consider alternatives if you need WiFi/app control, smart home integration, or whisper-quiet overnight bedroom operation
