Laboratory Tests
The Smoke Purification Testing​

We used PH smoke pellets to generate smoke. One of these small pellets can last over 40 seconds; making the smoke hard to dissipate. Goji can clean the smoke instantly, which proves it has the capability to clean any solid pollutants such as smoke, dust, pollen, mites, or PM2.5.

The VOC Purification Test

We used acetone[1] to test the ability to purify VOC. After we dropped the acetone in the beaker, it started to volatilise in the box and the VOC concentration indicated a drastic increase. In the end, the data was stable around 170ppm[2]. When Goji was turned on, almost all the acetone in the box was purified; showcasing the capability of Goji against VOC and other toxic gases.

[1]Acetone (propanone) is the organic compound with the formula (CH3)2CO. It is a colourless, volatile, flammable liquid that is the simplest and smallest ketone.

[2]ppm and ppb are the concentration units. ppm = parts per million. ppb= parts per billion. 1 ppm = 1000 ppb.

The Sterilisation Test

We used two Petri dishes for this testing. One of the Petri dishes was put in the open area while the other was put in a space with the Goji ‘On-the-Go’ . Then we turned on Goji ‘On-the-Go’ and timed what happened.

3 days (72 hours) later, the petri dish in the open area generated visible bacterial colonies, which means an exponential bacterial growth occurred. The Petri dish with the Goji ‘On-the-Go’ , however, looked the same as before. It proves Goji ‘On-the-Go’ is effective in killing viruses and bacteria.
