Whats the difference between the Friedrich C90B Air Cleaner and the Friedrich C90A Air Cleaner?
Although the basic construction of the Friedrich C90B Air Cleaner is the same as the Friedrich C90A Air Cleaner, the C90B air cleaner is the newest addition to this top-rated line of electronic air purifiers. Essentially, it is the Clean Air Delivery Rate (CADR) that has been improved in the C90B unit. The Friedrich C90B Air Cleaner delivers more clean air per square foot. While the Friedrich C90A delivers maximum efficiency for a space of 465 square feet, the Friedrich C90B delivers clean air at a maximum efficiency for a space of 506 square feet. Additionally, the Friedrich C90B outperforms the C90A in capturing pollen, tobacco smoke, and dust. The difference between the Friedrich C90A and C90B is clear. Friedrich has not only improved on the efficient design, but they have also yielded better performance rates with the newer Friedrich C90B.
