• Asthmatics & allergy sufferers: Particle sizes < 5 µm are considered respirable and < 2-3 µm are considered alveolar.

• Tobacco smoke elimination: Do you or your loved ones smoke ? Thanks to the WDH-660b and/or WDH-988b air purifiers incl. filters, not only is the unpleasant smoke from cigarettes, pipes, cigars, etc. absorbed and neutralised faster, but nicotine no longer has a chance to settle in your home and turn white into yellow !!!
