Air Purification: HEPA H13 Filtration
The PH03 uses a fully sealed HEPA H13 filter. This captures 99.95 percent of particles as small as 0.1 microns. This includes dust, pollen, pet dander, mold spores, bacteria and some viruses. The filter is sealed to prevent unfiltered air from bypassing the filtration system, which is a problem with lower‑end purifiers.
The purifier monitors air quality in real time. The built‑in LCD screen shows particulate matter levels, temperature and humidity. You can also view this data on the MyDyson app.
Filter life is approximately 12 months depending on usage and air quality. Replacement filters cost around 70 to 100 USD for genuine Dyson parts. Third‑party filters are available but may not perform to the same standard.
Humidification: 36 Hours Of Runtime
The PH03 includes a one‑gallon water tank. Dyson claims this provides up to 36 hours of continuous humidification on a single fill. The system uses hygienic humidification technology, which uses ultraviolet light to kill bacteria in the water before it is released into the room. This prevents the growth of mould and bacteria inside the water tank.
The humidification function is particularly useful in dry climates or during winter when indoor heating reduces humidity levels. Proper humidity levels can reduce dry skin, sore throats and static electricity.
Cooling Fan: Air Multiplier Technology
The PH03 works as a cooling fan in warmer months. Dyson‘s Air Multiplier technology draws in air and projects it across the room. You can choose between direct cooling (focused, high‑velocity airflow) and a gentle breeze simulation (more diffuse, natural feeling). You can also run the purifier and humidifier without the cooling fan, which is useful in winter when you want clean, moist air without a chilly draft.
The appliance does not include a refrigeration unit. It is an evaporative fan, not an air conditioner. It does not lower room temperature beyond the wind‑chill effect of moving air.
MyDyson App And Smart Features
The PH03 connects to your home Wi‑Fi and works with the MyDyson app. Through the app, you can:
- Monitor real‑time and historical air quality data.
- Control fan speed, oscillation and airflow direction.
- Set schedules for automatic operation.
- Monitor filter life and receive reminders for replacement.
- View temperature and humidity levels.
The purifier works with Amazon Alexa, Google Assistant and Siri Shortcuts for voice control. You cannot use voice commands to control the humidification function (you must use the app or remote), but you can turn the device on and off and adjust fan speed.
Dyson PH03 Vs PH04 Vs TP07
| Aspect | Dyson PH03 (Purify + Humidify + Cool) | Dyson PH04 (Purify + Humidify + Cool, updated) | Dyson TP07 (Purify + Cool, no humidify) |
|---|---|---|---|
| Functions | Purify, humidify, cool | Purify, humidify, cool (newer model) | Purify, cool |
| HEPA Filter | HEPA H13 (sealed) | HEPA H13 (sealed) | HEPA H13 (sealed) |
| Humidification | Yes (one‑gallon tank) | Yes (one‑gallon tank, potentially improved) | No |
| Water Tank | One gallon | One gallon (similar) | N/A |
| Runtime (humidify) | Up to 36 hours | Similar | N/A |
| LCD Screen | Yes | Yes (updated UI) | Yes |
| Price (deal) | 550 USD | 750‑850 USD (typical) | 500‑600 USD (typical sale) |
| Best For | Dry climates, allergy season, year‑round use | Same as PH03 (newer, more expensive) | Users who only need purification and cooling |
The PH04 is a newer model with minor improvements. The PH03 at 550 USD is a better value than the PH04 at full price. The TP07 lacks humidification, so it is less versatile but also less expensive.

Frequently Asked Questions (FAQs)
Does the Dyson PH03 actually cool the air?
No. The PH03 is an evaporative fan. It moves air across the room, creating a wind‑chill effect that makes you feel cooler. It does not lower the room temperature like an air conditioner.
How often do I need to replace the filter?
Dyson recommends replacing the HEPA H13 filter approximately once every 12 months, depending on usage and air quality. The MyDyson app will notify you when a replacement is due.
