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.
Can I trial it before buying?
Yes. The Classic 400S is available under the 30-day pilot — zero upfront cost, keep it only if the air-quality difference convinces you.
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.
