  • [Coarse Particles (PM10)]: Dust, pollen, smoke, soot, mould spores, pet hair.

  • [Ultrafine Particles (PM0.1)]: Smoke, bacteria, viruses, and fine aerosols from cooking.

How It Works:

  • [Fabric Pre-filter]: Captures larger particles like dust and pet hair before the air goes through the main filtration system, prolonging the life of other filters.
  • [HEPASilent™ Technology]: Airborne particles are given an electrical charge, which makes them adhere to the HEPA filter more swiftly and effectively. This dynamic combination of electrical charging and a strong air draft also neutralises viruses and bacteria, providing you with a healthier and fresher living environment.

  • [Smokers & Passive Smoke Exposure]: The top choice for cleaner air in smoky surroundings.
