Rank #7 in Best Air Purifier 2026: 10 Ranked on Real Air Changes
Philips 600 Series Air Purifier, CADR 170 m3/h, NanoProtect HEPA, 12W
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.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“I’ve had this a few months now, decent, I’ve definitely noticed I’ve woken up less sniffly over the months I’ve used it. Easy to clean and you can turn it on and off on the app, or just on the screen on top it’s optional. Very quiet and not had any issues at all, and I keep it on almost 24/7. Highly recommend, does the job well, and my bedroom is less dusty. It’s a really good pocket friendly air purifier!”
Verified purchase“So far so good. Not noisy like in some comments I read, yes you can hear the air blowing when you have it on high but we're not in space... You will hear the wind blow!I have it in my craft room an it makes the room comfortable an even helps cool it down when it's hot I've found.Easy to put together with the filter. It's pretty big though, not surprised given the dimensions it was as expected but still, different to see it in person an take sup counter space but it's all good for clean air.Price is ok for what you're buying. Hoping I can get a replacement filter when they're on offer by the time it's needed but should be a good while yet”
