Just barely touched on the medium purifying range category, PureZone 3-in-1 200 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.

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.

^ PureZone 3-in-1 replacement filters estimated cost
Affordable price tag is no doubt PureZone 3-in-1 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.

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.

In conclusion......

  • Affordable price tag with decent performance.
  • Very cheap bundled annual filter replacement cost.
  • Lightweight and compact framework.
  • Effective 3-in-1 filtration including Pre-filter, Activated Carbon Filter and HEPA filter.
  • 4-stage filtration including UV-C light.
  • 3 preset timer mode.
  • 5 years warranty to attentive customer support.
  • No dimmer to disable the Blue LED light that beams up with lights off.
  • Lacks Auto mode/ air quality indicator although expected at this price range.
  • CADR is far from best but again expected at its price.
