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
Result: 99.5% of Smoke Particles Removed. (Scroll down below the charts for more details.)
Smoke Particle Test Details
Smoke particles of various sizes are a good representation of particles in general, including allergens.

Smoke Particle Levels in Chamber WITH the New-Aire Air Purifier
It's going to take a seachange in public policy and a Herculean effort over many years to significantly reduce these tiny health-threatening particles from our environment. However, as you can see from the above test results the New-Aire XJ-3000C can help you make significant improvements in your indoor air quality today!

Smoke Particle Test - Why It's Important
According a study conducted by the USC Keck School of Medicine published in the New England Journal of Medicine September 9, 2004 identifying Southern California air as the the most unhealthy in the nation: the greatest danger appears to come from tiny particles typically produced in diesel exhaust, by road dust and in animal waste from large-scale farms.

Result: Hydrogen Sulfide reduced by 93%. (Scroll down below the charts for more 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.
