Design And Usability
Clarifion GL-139 is a great compact negative ion generator that can clean your air for less than 50 bucks. A clean and simple pluggable device that has the aesthetic and performance. At only 4 x 6 x 2.9 inches size and light 4.8 lb weight, you can fit it anywhere in the room without being obstructive. If you are a frequent traveler like me, GL-139 fits in a backpack or luggage with relative ease.
Clarifion GL-139 negative ion generator is very easy to use and install. Just find a wall socket, plug it in and you’re on. The light blue LED light will let you know the device is working and you can leave it be. No confusing controls, fan speed adjustment, or timer needed in the setup. Just make sure you do not impede the airflow or place it close to flammable materials.
As for the build quality and durability, Clarifion GL-139 pluggable negative ion generator comes with a standard 1-year warranty that covers all manufacturing defects. It is CARB Certification (G-20-016) thus will not produce harmful ozone or chemical byproduct. You can safely leave it running all day without having to worry about fire hazard risk.
Airflow, Coverage, And CADR
Clarifion GL-139 is a pluggable negative ion generator so there is a limited air purification performance. At a small 150 square feet of purifying coverage, it is usable but you will need multiple units to cover an entire room. We recommended placing Clarifion GL-139 negative ion generator in the bedroom, bathroom, staircase, basement, or storage room that has very little space to spare. No CADR here given GL-139 is a filterless device that does not rely on filters to clean the air.

Filters And Performance
Clarifion GL-139 negative ion generator can help to keep the air fresh and clean by removing airborne dust, smog, smoke, pet dander, and germs. The air ionization technology generates up to 10 million pcs/ cm^3 of Negative ions output. The diffused ions will negatively charge airborne pollutants ions causing them to bond. The bonded ions will then fall on a surface due to the increased weight allowing you to swept or vacuum away the contaminants. The key difference between an air ionizer and an air purifier is the latter relies on a fan to pull the air in through a series of filters to capture. It is very efficient but costly to run as the filters require replacing.Noise And Energy Usage

Clarifion Negative Ion Generator GL-139 VS The Challengers

GermGuardian GG1100W/ GG1100B
Instead of an ionizer, try this pluggable air sanitizer that uses UV-light filtration to kill bacteria and viruses. Ultraviolet light is more effective in eliminating germs but you will have to replace the light bulb.
GermGuardian GG1000 Pluggable
The older version to GG1100 and it is roughly the same price as Clarifion. Go with this if you prefer germ killing UV-light over a negative ion generator.Final Thoughts On Clarifion Negative Ion Generator GL-139
