Design and build quality

Holmes air purifier HAP9424BF-TUA is fantastically designed for a HEPA tower. With a dimension of 25.4 x 69.9 x 22 cm, this black plastic tower is consider tall for its segment. Nevertheless the 2.7 kg light weight makes up for the hassle-free portability. Manual dial knob, filter change indicator and air inlet are all located at the front of the Holmes air purifier HAP9424BF-TUA. The cover is also removable for filter change although its slightly tedious due to the shape of the air purifier.

Applicable area and CADR

The recommended coverage for Holmes air purifier HAP9424BF-TUA coverage is 19 m2 or 209 sq. ft. Not great but does the job as a bedside or desk purifier. Unfortunately due to the limited time we have with the air purifier, we did not go through the CADR test and the only official CADR we have its 126 cfm for smoke.
