The LifeAir IonFlow Evolution cleans the air through ionization. That means the air purifier doesn't have its own filters. Electrically charged particles (30 billion, to be exact) are blown into the air, which attract ultrafine particles, bacteria, pollen, viruses, fungi, and dust particles through the static collector in the purifier. That means you won't breathe them in anymore, so the air will be clean. This air purifier is suitable for spaces of up to 50m2, and has a maximum noise level of 21dB. It hardly requires any maintenance. It's a matter of rinsing the collector, where all the dirt is gathered, under the faucet, and you'll be done. The purifier comes with an included protective cover. This additional security is pleasant to have when you have pets and children.
Cleaning tip: once every 3 months, use a brush to clean the corona needles on top.
