RATIONALE:

There is a gradual rise of allergy and asthma cases all over the world. Particulate matter of size 2.5 microns are a major health concern in the present decade since, when inhaled they can reach deep into the lungs and tissues via the bloodstreams. These are generally composed of the combustion particles, organic compounds, metals. We analyzed the particle count in two fiber glass chambers to assess and evaluate the efficiency of the hybrid AHPCO or Advanced Hydrated Photocatalytic Oxidation and Plasma Nanotechnology in reducing the particle counts in the chambers.

METHODS: We evaluated the rate of the decay of aerosol particles on using the AHPCO and plasma nanotechnology. Through an inlet, the aerosols were injected and dispersed in the chamber in a controlled way and particle count was recorded using the DustTrack connected to the outlet. The DustTrack 8520 spectrometer counted the aerosols in the chamber on injecting 12 mg/m3 of NX solution into the chamber; we turn on the DustTrack and let the aerosols settle to the lowest concentration. We used the illite NX powder as aerosols since it has a similar mineralogical composition to atmospheric mineral dust. We also used a Dylos Air Quality Monitor to detect and compare the animal dander counts on running the air purifier for 24-120 hours of exposures in the animal vivarium.

RESULTS: A gradual reduction of the indoor particulate matters and animal dander was recorded with the progressive time intervals.

CONCLUSIONS: AHPCO and Plasma efficiently reduced the indoor particles and dander.
