Good – Carbon Flex filter
The Thermex Carbon Flex filter is a so-called "long-life" recirculation filter, which is most reminiscent of the traditional carbon filters in its way of cleaning the air. The Carbon Flex filter is filled with active carbon, but due to the innovative design, it can contain much more carbon, thus making the efficiency much higher than traditional carbon filters. As much as 73% of the air that passes through the filter is cleaned before it is sent out into the kitchen again. In comparison, the effect of a traditional carbon filter is around 40-50%, which means that the air must pass through the hood 3 times to be thoroughly cleaned.
The design of the Carbon Flex filter means that there is a very small pressure loss in the air flow when it is sent through the filter. Typically, a high filtration effect also means a very high pressure loss, since the method to achieve high effect has been to put a thicker layer of activated carbon in the filter. A high pressure loss means that the extractor hood cannot make full use of its suction power, and thus em and mados are removed less effectively. But with the cylindrical design of the Carbon Flex filter, the filtering surface is significantly larger, and thus you get the best of both worlds. High efficiency and low pressure loss.
In addition, the lifetime of the Carbon Flex filter is a full 2 years. In contrast to a traditional carbon filter which must be changed 2-3 times a year. This means that it is also cheaper to maintain compared to traditional carbon filters, and you also don't have to struggle to get hold of the correct filter that fits your specific extractor hood.
And when the 2 years have passed, you don't need to buy a new Carbon Flex filter. You can buy a refill of the activated carbon. The filter is opened using a screwdriver and the old carbon can be poured out of the filter and replaced by new carbon. And thus the filter is ready for another 2 years. Quite simple and sustainable.
