Price and rating as shown on Amazon when we collected them. Both change.
The Philips 600 Series is the smallest and most efficient purifier in this ranking. The listing quotes a CADR of 170 cubic metres per hour for rooms up to 44 square metres, using NanoProtect HEPA filtration, with a 19 decibel noise figure, just 12 watts of power draw and 2.2 kilograms of weight, controlled through the app.
Twelve watts is the number to note: it is the lowest draw here by a factor of two against the next machine, which for a device intended to run continuously is the difference that shows on the electricity bill. The trade is the lower CADR and smaller room coverage. At the time of collection it carried 826 ratings at 4.3 stars. Everything here comes from the Amazon listing rather than our own testing.
