At 6.1 x 27.3 x 9.5 in and 10.5 lb, GermGuardian AC5250PT is not particular huge or heavy; excellent if you need a well-balanced air purifier in terms of performance and size. Build quality is good except for the buttons that tends to cracked over a period of time. There are few premium touches that we particularly like such as the top chrome with glowing light. Thanks to the separate buttons and digital display, control wise is dead easy expect for the filter reset button that requires small object like paper clip. What’s included in the specification is a 4-stage filtration with UV-C Technology, Pet Pure antimicrobial, 5 fanspeed control, dedicated UV on/ off button, Filter replacement indicator light, programmable timer and impressive 5 years warranty.
