This is another product recommended by Dr Tom Wu. I felt it delivers a big impact for a fairly low cost. Food is becoming less safe in this age when there is tremendous pressure to drive the cost of food down. This inevitably implies widespread use of chemicals in agriculture.
An ozone sterilizer is an effective and convenient way to mitigate the problem. It is convenient because it runs on electricity and does not involve any consumables. It is also actually quite effective in killing bacteria and removing pesticide.
For only 188 Yuan (S$38), i think every household should have one. The manual lists a wide range of applications including sterilizing utensils and even the wardrobe or room (i.e. just let the device emit the gas into the air). You do earn cashback when purchasing this product as well.
