Design and Build Quality
The Dyson's 360° Glass HEPA + Carbon Filter (part number 965432-01) is designed to align with the look and fit of The air purifier's compatible Pure Cool tower units, rather than being a universal add-on. For the Dyson, the housing and sealing design focuses on maintaining a consistent interface with DP04 and HP04 models. It is a compact black module, weighing 1.1 kilograms, sized 11D x 20W x 22H cm, and intended for clean, straightforward swapping. Strengths include app or LCD change reminders, while exact servicing steps are not stated.
CADR and Room Coverage
CADR and room coverage for The air purifier's 360° Glass HEPA + Carbon Filter (part number 965432-01) depend on the Pure Cool tower it is installed in. This cartridge is described as a fit-for-purpose replacement for the Pure Cool air treatment unit, so practical air-cleaning performance follows the DP04 and HP04 purifier's fan performance, airflow, and chosen speed, rather than the filter alone. For real-world use, match the room size to the purifier's intended application, then use higher settings during heavier cooking odours or dust.
HEPA Filtration Performance
HEPA filtration using The Dyson 360's 360° Glass HEPA + Carbon Filter cartridge (part number 965432-01) is designed to capture very small particles. It is rated to trap 99.95% of harmful pollutants as small as 0.1 microns (PM 0.1). This matters for fine dust, allergens and ultra-fine particles that typical filters may miss. The sealed HEPA setup is intended to reduce bypass, while the carbon layer targets gases and odours. Performance depends on correct fit and regular replacement.
Noise Level and Sleep Mode
Noise output depends largely on the purifier's fan speed. On the Pure Cool/Desk Tower models compatible with this HEPA plus carbon cartridge, the settings are typically adjusted by user control or via the Dyson app. For the dyson 965432-01 360° glass HEPA plus carbon filter Pure Cool DP04 HP04, stronger cleaning modes will sound louder, while lower settings suit quieter rooms. The approach is to start on a low fan speed at night and step up only if the air feels stale. The dyson 965432-01 360° glass HEPA plus carbon filter Pure Cool DP04 HP04 pros and cons include improved purification coverage, but sleep comfort depends on keeping the fan speed low. Sleep mode behaviour is not stated.
Smart Features and App Control
Smart features add convenience rather than improved filtration. The system can also alert users through both the app and the LCD screen when a filter replacement is needed, helping prevent missed maintenance, although it still relies on app access and correct pairing. Connectivity does not improve filter performance on its own.
Filter Life and Cost
For the air purifier° Glass HEPA + Carbon filter used with the Pure Cool DP04 and HP04, filter and cost planning matters alongside app alerts. In the Dyson° glass HEPA + carbon filter Pure Cool DP04 and HP04 context, the main cost factor is replacement timing, since the filters are changed when the app or LCD notifies. The carbon section is designed to help with odours, so households with pets or frequent cooking may need to replace sooner. Replacement is straightforward, and using only genuine The air purifier filters is recommended.
Energy Use
Energy use depends on how this air purifier° Glass HEPA + Carbon filter performs when installed in the Pure Cool DP04 or HP04, because the replacement filter does not list an energy rating, operating wattage, or power draw. For the Dyson, the stated specifications focus on capture performance and fitment for DP04/HP04 models. Power use is therefore mainly driven by the purifier's own fan setting, the room size, and how often it is run on those controls. If it is used more frequently at higher levels, energy use increases.
Cleaning and Maintenance

For the air purifier° glass HEPA + carbon filter, install the replacement by unplugging the unit, removing the old filter, and fitting the new one securely.

Frequently Asked Questions
Does this air purifier really work?
Air purifiers do measurably cut airborne particles when sized to the room and run regularly. The Dyson draws air through its filter stages, so it works best matched to your room size and run on a higher setting when air quality dips.
Is the air purifier good for allergies and asthma?
Its HEPA filtration traps fine airborne particles, covering common triggers such as pollen, dust and pet dander. A purifier can ease symptoms indoors, but it is not a medical device - treat it as one part of managing allergies or asthma.
Is the Dyson quiet enough for a bedroom?
Run it on a lower fan speed overnight, as noise rises with speed.
What are the downsides of the air purifier?
The main ongoing cost is filter replacement, and a purifier only cleans the air while it is running. It tackles airborne particles rather than gases or smells unless it includes a carbon stage.
How often do you replace this air purifier's filter?
Filter life depends on usage and air quality, and a fixed interval is not always stated - replace it when airflow drops or odours linger, following the manufacturer's guidance.
Is the Dyson 360 worth it?
If you have allergies, pets, or live near traffic or pollen, a purifier like the air purifier earns its place. Factor in filter replacement costs, and check the current Amazon UK price as it changes often.
What type of filtration does the Dyson use?
It uses HEPA filtration.
