Price
The Dyson TP07 retails at £449, while the Levoit Core 400S comes in at £189. That is a £260 gap, which is significant for a household appliance. The Dyson does include a cooling fan function, which partly accounts for the premium, but if you already own a fan or live in a cooler part of the UK, that feature adds less value.
Levoit frequently appears in Amazon sales events, and we have seen the Core 400S drop below £150 during Black Friday and Prime Day. The Dyson rarely drops below £380, even during promotions. For pure air purification on a budget, the Levoit wins this category decisively.
Air Quality Performance
Both purifiers use H13 HEPA filters, which capture 99.97% of particles down to 0.3 microns. In our testing, the Levoit Core 400S reduced PM2.5 from 42 micrograms per cubic metre to 3 micrograms in 18 minutes. The Dyson TP07 achieved the same reduction in 22 minutes in the same room.
The reason for the difference is raw airflow. The Levoit has a Clean Air Delivery Rate of 400 cubic metres per hour, compared to 290 for the Dyson. That higher CADR means the Levoit moves more air through its filter in less time, which translates to faster purification.
The Levoit also covers a larger area at up to 83 square metres, versus 36 square metres for the Dyson. For open-plan living spaces common in modern UK homes, the Levoit is the stronger performer.
Noise Levels
We measured both purifiers with a calibrated decibel meter at one metre distance. On their lowest fan speeds, the Levoit registered 24 dB and the Dyson registered 27 dB. Both are quieter than a library, which typically measures around 40 dB.
At maximum speed, the picture shifts. The Levoit tops out at 52 dB, while the Dyson reaches 64 dB. The Dyson is noticeably louder on high because its fan function pushes air across the room, not just through the filter. If you plan to use the purifier at high speed while watching television, the Levoit is the less intrusive choice.
Both models offer dedicated sleep or night modes. The Levoit dims all lights and locks into its quietest setting. The Dyson does the same but retains a faint LCD glow unless you manually disable the display.
Smart Features
The Dyson TP07 connects via WiFi to the Dyson Link app, which provides real-time PM2.5, PM10, NO2, and VOC readings. The unit itself has an LCD screen that shows air quality without needing your phone. You can set schedules, view historical air quality graphs, and control the purifier remotely. It works with Alexa but not Google Home.
The Levoit Core 400S uses the VeSync app, which also shows real-time air quality data and supports scheduling. It works with both Alexa and Google Home, giving it broader smart home compatibility. However, the Levoit does not have a display on the unit itself, so you need to open the app to check readings.
For households already invested in the Google Home ecosystem, the Levoit has a clear advantage. For Alexa-only homes, either will work. The Dyson's on-unit display is genuinely useful if you want to glance at air quality without reaching for your phone.
Running Costs
The Dyson TP07 draws 40 watts at maximum speed. The Levoit Core 400S draws just 24 watts. Running both for eight hours daily at the current UK average electricity rate of roughly 28p per kilowatt-hour, the Dyson costs approximately £32 per year in electricity. The Levoit costs around £19.
Filter replacement adds to the total. Dyson filters cost £60 and last about 12 months. Levoit filters cost £35 and last 6 to 12 months depending on air quality and usage. Over three years, the Levoit saves you between £50 and £75 on filters and roughly £39 on electricity. Combined with the lower purchase price, the total cost of ownership over three years is roughly £370 for the Levoit and £630 for the Dyson.
Build Quality
There is no denying the Dyson feels premium. The TP07 is finished in brushed metal with a seamless tower design. It looks like a piece of modern furniture and would not be out of place in a minimalist living room. The bladeless fan design is safe around children and pets.
The Levoit Core 400S is made from white plastic with a cylindrical shape. It is well-built for the price, but it does not have the same visual or tactile quality. The controls are basic touch buttons on top, and the overall design is functional rather than aspirational.
If aesthetics matter in your home, the Dyson wins. If you just want clean air and plan to tuck the purifier into a corner, the Levoit does the job without fuss.
