An independent testing laboratory tested the XJ-3000C air purifier to determine its effectiveness at removing two typical pollutants in the air, small particles and hydrogen sulfide gas (H2S, often known as Sewer Gas). The results are impressive:

#1: 99.5% Removal Rate of Particles in Chamber

#2: Hydrogen Sulfide (Sewer Gas) Reduced by 93%

99.5% Removal Rate of Particles in a Chamber

Smoke Particle Levels in Chamber WITHOUT the New-Aire Air Purifier

Smoke particles are a good representation of particles in general, including allergens.

Measurements taken throughout the entire chamber.

Smoke Particle Levels in Chamber WITH the New-Aire Air Purifier

Measurements taken throughout the entire chamber, not just at the point where the air enters the air purifier.

Smoke Particle Test Details

Overall Result: 99.5% of Smoke Particles Removed
Chamber Size: 128 cubic feet (4' x 4' x 8')
Temperature: 75-80^oF
Humidity: 50-60%
Test performed by an independent testing lab.

Test Description:
Smoke particles of various microscopic sizes were pumped into the air-tight chamber in equal concentrations in both tests (Test A without the New-Aire air purifier, and Test B with the New-Aire in operation in the chamber). In Test A, without the air purifier, the particle levels did not decrease over the course of 7+ hours. With the same amount of smoke particles pumped into the chamber in Test B (with the New-Aire air purifier in operation) the concentration was brought down by more than 99.5% over the same period of time. Unlike the reduction rates quoted by most air purifiers, the measurements in this test were taken throughout the chamber, outside the New-Aire air purifier, making these results even more impressive. In other words, these test results are an indication of how effectively the New-Aire will remove airborne particulate throughout the room, and not just from the air that passes through the unit.

Hydrogen Sulfide Test Details

Result: 93% of Hydrogen Sulfide Removed
Chamber Size: 128 cubic feet (4' x 4' x 8')
Temperature: 75-80oF
Humidity: 50-60%
Test performed by independent testing lab.

Test Description:
Hydrogen Sulfide was pumped into the air-tight chamber in equal concentrations in both tests (Test A without the New-Aire air purifier, and Test B with the New-Aire in operation in the chamber). In Test A, a 5.8 ppmv concentration was maintained for over 2 hours. With the same amount of H2S pumped into the chamber in Test B (with the New-Aire air purifier in operation) the concentration was brought down to 0.41 ppmv over the same period of time, a 93% reduction. Unlike most air purifier reduction rates, the measurements in this test were taken throughout the chamber, outside the New-Aire air purifier, making these results even more impressive. In other words, these test results are an indication of how effectively the New-Aire will remove noxious chemicals throughout the room, and not just from the air that passes through the unit.

About Hydrogen Sulfide:
Hydrogen Sulfide (H2S), a strong gas created by stagnant sewage, is one of the very worst, and most difficult-to-remove pollutants known to man. An air purifier's ability to remove H2S is a good indication of its ability to remove strong odors and volatile organic chemicals (VOCs).
