Our testers found the top control panel to be very user-friendly, with an auto mode that uses the built-in sensor to adjust filter speed accordingly, and a handy digital display on the top that gives you real-time information on air quality levels. Named the 'Beko HygieneShield', this air purifier works to filter out the nasties in a room (up to 24m² large) with a system that contains a pre-filter, a HEPA 13 filter and a carbon filter. These combined filters banish dust, hair, pollen, and unwanted smells. It's not quite as quiet as the Blueair Blue 3210 air purifier on its lowest setting, offering noise levels of 24dB compared to the Blueair Blue 3210's lowest 18dB setting, but it's still pretty quiet compared to other options. However, like the Blueair Blue 3210, those noise levels do get considerably higher as you move up the fan settings.

According to the brand, the body of the briiv air filter unit is made 'completely from bioplastics derived from Elephant Grass with a bespoke and toughened recyclable glass display zone'. This zero plastic air purifier also utilises natural filters which biodegrade when disposed of, as opposed to the more common HEPA filters which briiv says 'are made out of fibreglass and other microplastics' and can therefore contaminate the environment. The Braun Scan & Clean BFD104BE is an air purifier that is specifically designed for smaller spaces such as a bedroom or home office. This air purifier is able to filter out impurities from the air that may affect the health and wellbeing of individuals. The device boasts an efficient HEPA filter that effectively captures particles such as dust, pollen, and smoke in the air. It also features an activated carbon filter which reduces bad odours. A powerful air purifier that's designed to fix air quality in larger spaces, the Philips Series 3000i Connected air purifier promises to remove impurities in areas up to 104m2. If you're using it in a smaller room, then that translates to super-fast results, with the unit able to purify the air in a room of 20m2 in less than 6 minutes, thanks to an impressive CADR (Clean Air Delivery Rate) of 520 m3/hr.

It wins on a few practical points too, with a useful foldaway handle and a minimalistic control panel that isn't a headache to get working. This air filter also has Smart capabilities and can be connected to an App for remote operation. Sadly, in practice, we found the briiv's controls – both manual and App-based – a little fiddly and unresponsive.

Features a permanent and washable mesh pre-filter that captures larger particles, dust and pet danderThe Meaco MeacoClean CA-HEPA 76x5 air purifier is a really great all-rounder which, despite not topping the other appliances on this list in areas like CADR, power consumption or quiet operation, performed solidly in our tests.
