Nano Titanium Wasabi Air Purification
A cutting-edge technology that uses a wasabi-modified Nano Titanium catalyst to provide a powerful antibacterial, anti-mould, anti-allergen, and deodorizing effect.
Comparison of Effects
Conventional anti-bacterial agents vs. Nano Titanium agents: Visual comparison indicating that Nano Titanium agents provide a higher removal ratio for bacteria and odors compared to conventional agents.
Ammonia Deodorizing Effect
A graph titled "Ammonia Deodorizing Effect" shows the percentage of odor removal over time. The Nano Titanium Wasabi Filter achieves 82% Odour Removal after 60 minutes, significantly outperforming the Plain Filter.
? *2 Test material: Nano Titanium Wasabi Air Purifying Filter (30.8 x 27.6cm 5T), Reactor volume: 1m³. Analysis: Gas Detector Tube Method. Flow rate through kit: 1m/s. Tested by the Nanopac Testing Laboratory.
