Just barely touched on the medium purifying range category, PureZone 3-in-1 True HEPA air purifier 200 sq. ft. purifying coverage is not the widest in its class, at its overall dimension and targeted segment category, the 3 speed airflow output would be sufficient for small to medium room size i.e. bedroom.

Each filters work exactly as they should with the pre-filter capturing dust/ large particles, Activated carbon filter for smoke/ odor and HEPA filter handling micron size allergens as small as 0.3 microns.

Keep it down

Noise level
30 - 50 dB
PureZone 3-in-1 power consumption
Power consumption
60 W
PureZone 3-in-1 is often advertised with Whisper-Quiet Operation though in reality, the result is slightly off but still relatively silent. At 30 - 50 dB noise level, you should expect some mild noise at speed 1 and audible fan noise at speed 3. Power consumption is also pretty standard across the compact segment category that would not bring too much damage to your electricity bill even when running 24x7.

^ Replacement filters/ estimated cost
Affordable price tag is no doubt PureZone 3-in-1 True HEPA air purifier main forte however, we would pick the super low annual filter replacement cost as it is a rarity in modern days air purifier. What makes it special other than the cheap price tag is the replacement filters comes in a bundled package so you would only require changing twice a year for the entire filters. If you plan to use the air purifier for at least couple of years ahead, this would be the right model.

PureZone 3-in-1 VS the challengers

Levoit LV-PUR131

Better purifying coverage and can work as a night light (great for little one) although price tag and annual cost is slightly higher.

GermGuardian AC4100

Cost half less with an even smaller and lighter body. Performance wise is not great, lacks dedicated carbon filter and UV-C light.

Final thoughts on PureZone 3-in-1
