Statement :
Texas Tech University testing showed that the ASIET air purification process significantly reduced live E. coli bacteria over a 60-minute test period. The bacteria were not directly exposed to UV light, which supports the effectiveness of the UV-activated TiO2 filtration process.
This test looked at whether the air purification unit could kill E. coli bacteria. E. coli was used because it is a common test bacteria in labs. If bacteria are alive, they grow into visible spots on a lab plate called colonies.
The main idea was simple: put E. coli near the purifier’s treated filter area, wait different amounts of time, then count how many bacteria were still alive.
The control plates were marked TNTC, which means too numerous to count.
That means the untreated E. coli grew so much that there were too many colonies on the plate to count. In normal words, the bacteria were very much alive when they were not treated.
The E. coli plates were placed close to the TiO2 filters. Those filters were exposed to UV light, which is part of the PCO process.
The important part is this:
The bacteria were not directly exposed to the UV light.
That means the test was not just shining UV light straight onto the bacteria. Instead, the test showed that the UV-activated TiO2 filter area had an effect on the bacteria nearby.
In the first experiment, the bacteria count dropped over time:
That means the longer the bacteria were exposed to the purifier’s treated area, the fewer living bacteria remained.
In the second experiment, the same pattern happened:
That is a clear downward trend.
The test showed that the ASIET-style PCO system was able to greatly reduce living E. coli bacteria over time.
The biggest reduction happened by the 60-minute mark. The longer the bacteria were exposed near the UV-activated TiO2 filter, the more the bacteria count dropped.
A simple way to say it is:
Texas Tech testing showed that the purifier’s PCO process reduced live E. coli bacteria over time, even though the bacteria were not directly exposed to UV light.
Some air systems only trap particles in a filter. This test suggests the technology was doing more than just trapping material. It was helping kill or deactivate live bacteria.
That matters because E. coli was alive at the start. After exposure to the system, far fewer bacteria were able to grow on the plates.
This test does not prove the machine removes every germ, virus, mold spore, or pollutant in every real building.
It also does not prove results for all bacteria or all room conditions. This test was specifically focused on E. coli under a controlled lab setup.
Statement :
Texas Tech testing showed that the ASIET 7710 Air Purification System reduced Candida albicans by 94.3% overall and Candida auris by 75% overall on contaminated surfaces after a 24-hour treatment period in a controlled test room.
This lab test looked at whether the ASIET 7710 Air Purification System could reduce two types of yeast on contaminated surfaces: Candida albicans and Candida auris. The report says the test was done at the Biological Threat Research Laboratory at Texas Tech University, with Steven M. Presley, Ph.D. as the principal investigator.
In plain English, the lab placed contaminated materials inside a sealed room with the ASIET machine running. The materials included cotton cloth, stainless steel, and plastic discs. These were placed in different spots and at different heights in the room, then exposed to the machine for 24 hours.
After the 24-hour treatment, the samples were taken back to the lab and watched for 10 days to see whether the yeast would grow back. If growth happened, that meant some organism survived. If no growth happened, that meant the treatment worked on that sample.
For Candida albicans, the ASIET machine performed very well. The report showed:
That means most of the treated Candida albicans samples did not grow after treatment.
For Candida auris, the results were lower but still showed reduction. The report showed:
That means the machine reduced Candida auris, but it did not perform as strongly against Candida auris as it did against Candida albicans.
This test showed that the ASIET 7710 helped reduce yeast contamination on surfaces after running for 24 hours in a controlled room.
The strongest result was against Candida albicans, with 94.3% overall effectiveness. The result against Candida auris was more moderate, with 75% overall effectiveness.
This matters because the machine was not just tested in theory. Contaminated materials were placed around a room, the machine was run, and the samples were later checked to see if the organisms could still grow.
That makes this a useful lab result for showing that ASIET technology can help reduce certain surface-based microbial contamination under controlled conditions.
This test does not prove that ASIET removes every germ, fungus, virus, or mold spore in every building.
It also does not prove instant results. This was a 24-hour exposure test, followed by a 10-day lab observation period.
