In our standard anti-perspirant spray test, the DustMagnet got us down to safe levels within two minutes, with most of the work being done within the first 60 seconds. It’s just as good as an air purifier too, though its CADR rating is slightly below that of the purifier-only Pro P2.

Make sure the power cord is not running across highly trafficked areas to prevent fraying, overheating, and tripping.The centrally placed LED touch display is integrated into the slightly angled top and tilts towards the user.

Always turn off the air purifier and unplug it from the electrical outlet before replacing the filter.

The HoMedics stays quiet at its lowest two settings, but noise levels ramp up on its highest setting to around 54. Do not use the appliance in wet surroundings or in surroundings with high humidity or high temperatures.

The sleeve has an elastic section with a Velcro closing that you remove to change the filter, and getting it back on again can be a faff. What’s more, link it to the hOn app over Wi-Fi, and the H-Purifier 500 will respond to other changes, including high pollen levels, soaring temperatures or pollution.

It’s quiet, too, putting out little more than a whisper at its lowest settings or when set to its advanced auto mode.
