Which brand of fume purifier is better?

It is recommended to use the German express bus fume purifier, the purification rate is about 98%, and the black smoke and thick smoke enter two to three meters, and the smoke-free effect is achieved by visual inspection. Even if you stand at the air outlet and see only the hot air generated during cooking, the electric field adopts nano-gold superconducting technology, which reduces the cleaning times. Cleaning is very simple, and you don't need to pay someone to clean it. Just take out the electric field, wash it with a high-pressure water gun, dry it and put it in the box, which greatly reduces the cleaning cost.
