About this deal

Again like the Pro P2, it’s quiet, with the noise barely noticeable at the lowest speed in purifier mode. test it brought the levels down to double figures within a minute, and they kept on ticking downwards, where other compact purifiers seem to struggle the closer the count gets to safe levels. Some purifiers are even packing in Wi-Fi connectivity and apps, so you can set the purifier going before you get home from the office or control it from your phone. You have the right to object, on grounds relating to your particular situation or where personal data are processed for direct marketing purposes, at any time to processing of your personal data which is based on art. Do not use the appliance in wet surroundings or in surroundings with high humidity or high temperatures.

The quality of our products, their economy and environmental safety are all of equal importance to us and all environmental protection legislation and regulations are strictly observed.For additional information on the environmentally compatible disposal of old electrical and electronic appliances, please contact the relevant local authorities, your household waste disposal service or the retailer where you purchased the product. There’s also still a lot of discussion about the extent to which many viruses are spread through the air or transmitted through contact with respiratory droplets.

In fact, we only have one quibble: with no carrying handles and its slightly slippery matt white plastic casing, it’s a tricky beast to move from room to room. It’s really designed for small spaces of around 10m², but we found its performance better than the 80m³/h CADR might imply. Meanwhile, the coloured indicator on the front gives you a quick appraisal of the current air quality, glowing blue to red. Key specs – CADR: 187m³/h; Max room size: 80m²; Power settings: 3; Dimensions (HWD): 22 x 22 x 36cm; Weight: 3. With just three speed settings, three timer settings and a sleep mode, the controls are fairly basic, and the only indicator is an LED ring that fades from red through amber to green as the filters do their work.

You can also evaporate essential oils by adding an absorbent pad to the tray just above the output fan.

In warnings, signal words at the beginning of a warning are used to indicate the type and seriousness of the ensuing risk if measures for minimizing danger are not taken.It’s also worth comparing manufacturer figures for the maximum size of room as these can vary enormously, sometimes when the CADR doesn’t. In some cases, but only if appropriate data protection is ensured, personal data might be transferred to recipients located outside of the European Economic Area and the United Kingdom. The permissions of Consumer Credit Compliance Limited as a Principal firm allow Bosch Thermotechnology Ltd T/A Worcester Bosch Group to undertake credit broking.

The centrally placed LED touch display is integrated into the slightly angled top and tilts towards the user. We then run standardised tests, spraying a test aerosol inside a small room for five seconds and using an air quality meter to record particulate levels.Otherwise, this has the same advantages as the smaller version: effective three-stage filtering, a built-in humidifying function and Sharp’s Plasmacluster ion technology, which – while it sounds like a weapon from a Halo game – works to kill odours, bacteria and mould. Just set it in its Auto mode and it will run, continuously adjusting the fan speed, until the air quality stays in the safe green zone for over 30 minutes, at which point the fan will turn off. Key specs – CADR: 240m³/h; Max room size: 20m²; Power settings: 4; Dimensions (WDH): 51 x 19 x 53cm; Weight: 5.
