Our Verdict
The PureZone 3-in-1 offers very quiet operation, but otherwise didn't particularly impress us in any capacity. If quiet operation is at the top of your purifier wish list, and you've got a budget of less than a couple hundred, the PureZone is a good choice. If you want something quiet and powerful, you'll have to spend a bit more on the Coway AP-1512HH. If you don't mind some fan noise the GermGuardian AC4300BPTCA is less expensive, more powerful, and likely a better use of your money.

Our Analysis and Test Results
Apart from very quiet operation, the PureZone 3-in-1is an average performer. If you're sensitive to noise and plan to use your purifier in a small (~100 square foot) bedroom, it will probably serve you well. However, it doesn't have the power to keep larger rooms clean.

Performance Comparison
After our rigorous testing procedure was done, the PureZone 3-in-1 sat right in the middle of our scoresheet. You can read more about its specific performance in all of the different tests we conducted below.
Air Cleaning Performance
The PureZone 3-in-1 was an average performer in our air cleaning tests. When placed into our smokey, 150 square foot testing room it struggled a bit to get going, removing only 83% of the airborne particulates over the first half hour (for comparison, the top performing Coway removed over 99% in the same time span). After an hour it was able to increase that reduction to 96%. This means that the PureZone will likely be able to keep small bedrooms (~100 square feet) mostly allergen free, but it will likely struggle a bit in larger spaces. If you need more cleaning power on a budget, the GermGuardian AC4300BPTCA would be a worthy alternative.
We think the PureZoe is great for small bedrooms, but would struggle to remove all the airborne particulates from a larger living space.

Does UV Purification Work?
The PureZone also offers a UV light that is meant to kill microorganisms in the air moving through it. While this technology has been proven effective in industrial scale unit used in hospitals, this technology is largely unproven in household units. Also, UV lights can sometimes produce ozone, which is a lung irritant. If you want to err on the side of caution, you might want to keep this feature turned off.

Noise
This is where the PureZone really shines. it is nearly silent on its low setting. On medium and high it emits a fairly low pitched hum that certainly isn't offensive, and some may even find it to be a pleasant white noise. This again adds to its usefulness as a small bedroom machine, as you'll likely be sleeping in close vicinity to the machine. If quietness is your first consideration in buying a purifier, we think the PureZone is the best deal you're going to find. Otherwise, you have to spend a lot more on a high powered yet quiet machine like the Coway.
Ease of Use
The PureZone offers an average user experience. Setup is a breeze and the simple control panel lets you easily dial in your preferred settings. We also really liked that this more basic machine offers an automatic off timer. It's really nice to know your purifier will shut off when you head to work, even if you forget to do it yourself. The PureZone is also relatively light at 8.45 pounds, and is easy to move around due to the built-in carrying handle.
The PureZone features simple controls for adjusting fan speed, setting the off timer, and turning the UV light on and off (again, we would suggest leaving it off).

The only downside of the PureZone's user experience is that fact that it lacks many of the bells and whistles of the higher priced models. That means no remote control, only 3 fan speeds, and no built-in air quality meter. These features are by no means necessary, but they do add a degree of convenience.
Operating Cost
The PureZone is a decently economic machine. Taking into account a relatively low street price of $100, inexpensive $17 replacement filters, and fairly efficient electricity usage of 0.02kWh per hour, we calculated an estimated lifetime cost of $323 (assuming a lifespan of 5 years). This is well below the average.
Value
There is one situation where the PureZone is a good value: if you both plan to use it in a small (~100 square foot) room, and you are sensitive to noise. In that case, you get a nearly silent machine that will effectively clean the air in your room for a reasonable price of $100 (it actually lists for $140, but regularly sells for $100 at online retailers). If you need more power than that or don't care about a slightly louder fan, the GermGuardian AC4300BPTCA is a more powerful machine at the same price.
Conclusion
The PureZone is somewhat of a niche product, It offers a good value for use in a small room with noise sensitive occupants. Otherwise, there are better models available in the same price range.
