KNKA APH4000 Air Purifier

Why we like it

Put air care where you spend your time. The KNKA APH4000 uses multiple air intakes and outlets, with published CADR figures to help compare its cleaning capacity. It is an option for a room where you want a dedicated purifier. Match the room and desired air-change rate to the model, and include replacement filters in your comparison.
