Which is better? – moulded plastic casing or steel casing?

Winix air purifier’s modern moulded plastic style casing is light weight, durable, safe, attractive and importantly, provide for maximum air purification. Moulded plastic casing is the most preferred option of leading manufacturers.

Whilst some air purifiers may have steel construction these can prove to be excessively heavy (20+ kg) & may limit portability of the air purifier around home or business (especially where stairs are used).
