Common questions
Classic 400S FAQ
Why is the Classic 400S called the flagship?
It carries AIRE's complete 7-layer purification stack — from aluminium prefilter to UV-C and anion release — in a mid-size unit that fits most rooms.
How do I know it is right for my room?
Send us the room dimensions and our free Air Report works out the air changes that room needs and whether the Classic 400S reaches them. If it does not, we upgrade it at no extra cost.
How loud is it at night?
Between 30 and 55 dB depending on fan speed; sleep mode keeps it at the quiet end for overnight use.
