Filters for healthy refrigerators

At room temperature, the number of bacteria on food can double every 20 minutes, posing a health risk. Low temperatures are one of the best ways to slow the growth of bacteria. However, the refrigerator alone does not protect against infections and, in the worst case, is a breeding ground for dangerous bacteria.

The dangers of bacteria from a refrigerator

End consumers have high demands on the quality and duration of food preservation. Low temperatures in the refrigerator can only slow down the growth and multiplication of bacteria, but not prevent it.

In particular, persistent bacteria such as Listeria, Salmonella, Staphylococcus aureus or Escherichia coli continue to pose a risk. In summer, fruits such as melons are a good breeding ground for listeria in the refrigerator, and meat or meat products can easily become carriers of salmonella. In addition to mild illnesses, they can also cause serious complications and diseases such as meningitis.

In addition to these dangers, bacterial growth also leads to a loss of nutrients from the food stored in the refrigerator. Bacteria use the nutrients of fresh food for their metabolic process. The fewer bacteria, the more nutrients are preserved.

Refrigerator odour: a health hazard that should not be ignored

Although refrigerators can keep low temperatures for a long time whilst they are sealed and closed space, the spoilage of food can be accelerated due to stubborn bacteria in the refrigerator and improper food storage habits. This may result in unpleasant odours. In addition, the odours also come from the smell and harmful substances volatilized by the materials of the refrigerator itself and the food stored. These odours contain many harmful substances such as toluene, benzene, and formaldehyde which may lead to decreased immunity, anemia, and even cancer due to long-term contact. Eliminating odors in the refrigerator is therefore an important health factor that consumers should pay attention to and manufacturers should not neglect.

Sterilization and deodorization filters prevent the breeding of bacteria and stop odors
Refrigerator Carbon and Platinum Filter Parameters
Trimethylamine removal rate > 90%
Methanethiol removal rate > 90%
Staphylococcus aureus removal rate >99%
Enterobacterial removal rate >99%

Freudenberg Filtration Technologies' carbon and platinum filter use chemical decomposition, which reduces bacteria concentration by promoting the oxidation reaction in the air after ingesting formaldehyde, destroying the biofilm and internal structure of bacteria, and decomposing bacteria into water and carbon dioxide. The combination of both refrigerator filters can not only ensure food safety, but also effectively reduce unhealthy odors. With the inhibition of bacteria growth as well as the deodorizing effect, refrigerators become safer.

Freudenberg Filtration Technologies provide the best customized filter and filtration solutions with a comprehensive range of services and co-innovation.
