Filtration Technology
The HP07 uses Dyson's fully sealed 360° Combi Glass filter combining H13 HEPA media with an activated carbon layer in a single 2-stage unit. The H13 HEPA grade captures 99.95% of particles as small as 0.3 microns , including fine dust, pollen, mold spores, and bacteria , while the carbon layer absorbs VOCs, smoke, cooking odors, and household pollutants.
Unlike standard HEPA machines that may leak unfiltered air around seals, Dyson's sealed system ensures all air passes through the filter media.
Noise & Performance
The HP07 reaches 62 dB at maximum speed, which is comparable to normal conversation , fine for daytime use but potentially disruptive at night for light sleepers. Customer feedback actually praises its quieter lower speeds, and the auto mode typically operates at reduced levels unless it detects a pollution spike.
The 73 sq ft coverage area means this air purifier is engineered for bedrooms, nurseries, or small offices rather than open living spaces.
Smart Features & Controls
This is one of Dyson's most connected purifiers, offering WiFi via the Dyson Link app for real-time air quality data, remote control, and scheduling from anywhere. It supports voice control through Alexa and Siri, and includes a physical remote that magnetically attaches to the top of the machine.
The auto mode with built-in air quality sensors stands out , it continuously monitors particulate and gas levels, adjusting purification speed without manual intervention.
Filter Maintenance
The HP07 uses the Dyson 360° Combi Glass HEPA + Carbon filter, a single combined unit that Dyson recommends replacing approximately every 12 months depending on usage. There's no washable pre-filter , when the filter indicator signals replacement, you swap the entire sealed unit.
Replacement is straightforward: the outer shroud removes to expose the cylindrical filter for a quick tool-free change, though the proprietary filter design means you'll need genuine Dyson replacements.
Who Is This Air Purifier For?
Ideal For
- ✓ Small home office or studio apartment dwellers who want purification, heating, and cooling in one compact 12 lb machine
- ✓ Allergy and asthma sufferers in small rooms , H13 HEPA captures pollen, dust mites, and pet dander while auto mode reacts to rising allergen levels
- ✓ Smart home enthusiasts who want app-based air quality monitoring, voice assistant control, and scheduled operation
- ✓ Pet owners in compact spaces , the activated carbon filter neutralizes pet odors while HEPA captures dander and fine hair particles
Not Ideal For
- ✕ Large room or whole-house coverage needs , at 73 sq ft, this machine cannot handle living rooms, and you'd need multiple units for broader coverage
- ✕ practical buyers , Dyson's premium tier means higher upfront cost and proprietary replacement filters
- ✕ Anyone needing a primary heat source , the heater function supplements but doesn't replace a dedicated heater for cold climates
Setup is minimal , remove the outer shroud, install the pre-packaged 360° filter, snap the shroud back on, and plug in. WiFi pairing through the Dyson Link app takes a few minutes and unlocks app control, air quality history, and scheduling.
Run the purifier on max for the first 30 minutes in a sealed room to establish a baseline air quality reading in the app
Place at least 3 feet from walls for optimal 360° airflow circulation
Dyson typically offers a 2-year warranty on their purifiers covering parts and labor, with registration through the Dyson app or website. Verify current warranty terms directly with Dyson, as coverage details may vary by retailer and region.
FAQ
How effective is the Dyson HP07 at removing allergens and pollutants?
The HP07 uses H13 HEPA filtration that captures 99.95% of airborne particles down to 0.3 microns, including pollen, dust mites, pet dander, and mold spores. The sealed filtration design ensures pollutants can't bypass the filter.
Auto mode detects rising allergen levels and increases fan speed automatically.
Can the Dyson HP07 actually heat a room?
The HP07 heats and purifies simultaneously, and customers report it warms up fast in small spaces. However, with a 73 sq ft coverage area, it's best as supplemental heating for a bedroom or office , not a replacement for a central heating system or dedicated space heater in larger rooms.
How loud is the Dyson HP07 at night?
At maximum speed the HP07 reaches 62 dB, but most users run it on lower speeds or auto mode overnight, which is significantly quieter. Customer feedback generally praises its quiet operation at reduced settings, though very light sleepers in small bedrooms may still notice it.
How often do you need to replace the filter on the Dyson HP07?
Dyson recommends replacing the 360° Combi Glass HEPA + Carbon filter approximately every 12 months. The machine has a filter change indicator that alerts you when replacement is needed.
The filter is a single sealed unit , there's no washable pre-filter, so the full cartridge gets swapped.
Does the Dyson HP07 work with Alexa and smart home systems?
Yes, the HP07 connects via WiFi and supports voice control through Amazon Alexa and Apple Siri. The Dyson Link app provides remote control, real-time air quality monitoring, scheduling, and usage history from your phone , making it one of the most connected air purifier machines on the market.
Is 73 sq ft coverage enough for a standard bedroom?
A 73 sq ft rating covers roughly a 9×8 foot area, which is smaller than most standard bedrooms (typically 100-150 sq ft). The HP07 will still improve air quality in a slightly larger room, but for optimal purification with adequate air changes per hour, it's best matched to small bedrooms, nurseries, or home office spaces.

Bottom Line
