TEQOYA works with a lab expert in air quality to make sure about the performance of its products. Our purifiers use a physical phenomenon known as eliminating particles of all sizes: the ionization of the air. Here are the results of tests on clearance of particles by our devices.
No ozone emission was detected during the Teqoya ioniser operation: ozone density was similar and measured below 4.5 μg/cm3 with or without ioniser during experiments (except during cigarette combustion time).
On the chart below, a cigarette is burnt in the room. The measure of particles density is done at a roughly 2m distance from the ioniser. As soon as the ioniser is turned on, particles decay accelerates. In various test conditions, particles decay acceleration is 70% to 150% higher than reference tests without air purifier.
In another test the ioniser was turned on before cigarette combustion. This test is closer to normal condition as the ioniser should never be turned off (its very low power consumption as well as the absence of noise allow continuous usewhich is recommended to insure continuous air cleansing). The chart below illustrates that ionised air decreases pollution peaks and accelerates air purification.
Tests run in the smaller room (13m2 surface area) showed a similar efficiency and a faster particles decay than without ioniser.
Tests performed in a Swiss public laboratory proved that toxic by-products levels are very low even very close to the ioniser's needles (1cm and 10cm). The difference between ozone level and nitrogen dioxide level with or without ioniser is of the same order as the measurement uncertainty (2 ppb), meaning that the variation is below the measurement apparatus accuracy.
Tests were performed by APAVE (private testing and measurement laboratory) in a french hospital to assess the impact of the ioniser on the density of 0.5μm particles. The particles density reduction with the ioniser is 70% higher than without ioniser.
