PureZone 3-in-1 True HEPA is a compact, sleek and modern air purifier at only 6.9 x 12.1 x 10.8 in size and 8.4 lb weight. Not the lightest but still fairly easy to carry it around the house. Design wise, it is standard with a magnet lock front panel that hides the filter and UV-C light. Air inlet is located at front sides while air outlet is at the top surrounding the control panel. We have no issue with the fitting and durability.

Let’s talk about the touch panel. There are four round buttons with small indicator lights just above it. To the most left is the Power button that also works as a Filter reset button. Tap to turn on/ off, press and hold for 5 seconds to reset the filter reset countdown. Next to it is the Speed button that allows you to cycle between L (low), M (medium), or H (high). The dual function UV-C/ Sleep button is a tad confusing so bear with me on this. On repeated tap, you can either select UV-C, Sleep mode, activate or disable off. Sleep mode set the fan speed to low and disable all indicator light. To the most right is the timer button that will cycle between 2, 4, 8 hours and off. Overall, buttons are well-spread and easy to use but lack tactile feedback.

At this affordable price range, you’ll get a good amount of features. From the 4-stage filtration with UV-C light, 3 fan speed, 2, 4, 8 hours pre-set timer, and filter change indicator. An industry-leading 5 years warranty is also bundled in the package.

PureZone 3-in-1 True HEPA air purifier 200 sq. ft. purifying coverage is not the widest in its class. Given its overall dimension and targeted segment category, airflow output is sufficient nonetheless. The 3 speed is decent for small to medium room size use. There is also the earlier mentioned sleep mode that would be ideal for night time.

CADR clearly reflected on the average airflow coverage and distribution. The all three dust, pollen, and smoke 80 cfm output are not too impressive. Again for this price range is understandably so. The air purifier would cover close range contaminants well with given time.

^ PureZone 3-in-1 filters/ technologies/ lifespan
Most "cheap" air purifying machine that comes with a 2 or 3 stage filtration top. PureZone 3-in-1 comes with 4-stage filtration including Pre-filter, carbon, HEPA filter, and a class unique UV-C light. Each filter works exactly as they should with the pre-filter focus on large particles. Beneath it is the carbon filter that focuses on smoke and odor particles. Next is the main True HEPA filter that traps allergens as small as 0.3 microns. Finally, UV-C light specializes in eliminating germs that travel along with the airflow. All in all, we appreciate the inclusion of True HEPA and UV-C light, but the filter is on the small size. Expect only half of a normal filter lifespan.

PureZone 3-in-1 is often advertised with whisper-Quiet Operation. In our test, the 30 - 50 dB noise level is not completely silent but still liveable. Expect mild noise at low speed and background noise at high speed. Power consumption is low across the compact segment category. It will not cause a dent on your electricity bill even when running all-day, every day at max speed.

The affordable price tag is no doubt PureZone 3-in-1 True HEPA air purifier main forte. What makes it even more special is the low filter replacement cost that comes in a bundled package. The filter set can be purchase easily online and you would only need to replace it twice a year (on normal use).
Amazon is the only price you should consider PureZone air purifier. It has the best deal, free shipping (Amazon choice) and hassle-free, 30 days return policy. PureZone official website does carry the model but is selling at a normal retail price. Same goes with retailers like Best Buy, Home Depot that usually offers a higher price than Amazon.

PureZone 3-in-1 VS the challengers

Levoit LV-PUR131

A better performer with wider purifying coverage and stronger CADR output. This is at a cost of higher selling price, bulkier body, and UV-Light omission.

GermGuardian AC4100

Another popular option that cost even less with an even smaller and lighter body. Performance wise is not great as it lacks a dedicated carbon filter and UV-C light. It is also a dated model.

Levoit LV-H132

Cheaper, lighter and comes with an adjustable night light (great for little one). CADR is also slightly higher but loses out on purifying range, carbon filter and UV-light.
Winix 5300-2 PlasmaWave

Winix 5300-2

Top up a little bit more, you will get yourself a console air purifier with full-size filter. Enjoy all-round upgrades other than the lack of UV-light (again).
