After investigating air purifiers for airborne allergy sufferers, I decided the Coway AP-1008CH was the most recommended choice at a reasonable price point. Ordering was simple and despatch was very quick. When the unit arrived it was a simple case of removing the wrappings, reading the user instructions and selecting its location. All very easy and then came the moment of truth - switching it on. In “Silent” mode the unit is just that, and ideal for the bedroom. In “Turbo” mode it shifts a lot of air and, like most fans, makes some noise - but it is not really intrusive. The unit is very stylish and light enough to move to another room, if required, but I expect I will buy another one for the lounge area if it is as good as most other users claim. Excuse the pun but Andatech were a “breeze” to deal with.
