Brand: Philips

Philips doesn’t muck around when it comes to clean air. This powerhouse pairs a clever dual-fan design with a three-layer filtration system that traps 99.97% of particles as small as 0.003 microns - that’s smaller than most viruses. This means it can help clear out everything from fine dust and smoke to pet dander, pollen and even some airborne nasties you can’t see. Thanks to SilentWings technology, it’s also up to 50% quieter than previous models, operating as low as 15dB in sleep mode.

What really makes it stand out is the smart connectivity. AeraSense technology scans your air 1,000 times per second, while the Philips Air+ app lets you monitor indoor and outdoor air quality, set schedules and control it all with your voice via Google or Alexa. Plus, it’s energy efficient, drawing just 36W at maximum power - less than a light bulb.

Best for: Tech savvy people who like connecting their appliances and gadgets, large homes and anyone chasing professional-grade filtration with smart features.

This is Dyson’s most powerful and quietest air purifier yet - and it’s genuinely impressive. The BP03 features advanced three-stage HEPA H13 filtration that captures and destroys harmful pollutants including formaldehyde, nitrogen dioxide, carbon dioxide and other volatile organic compounds.

Despite that power, it runs at just 56 dBA on full speed - quieter than a normal conversation. The adjustable oscillation (0°, 25° or 50°) and Breeze mode mimic natural airflow for a more comfortable experience.

Smart sensors analyse pollution levels 1,000 times per second, while the MyDyson app gives you detailed air quality insights - tracking PM2.5, PM10, VOCs, NO₂, temperature and humidity. In testing, it turned a heavily polluted room into clean air in just 13 minutes.
