Why Is Sterile Air Filtration Important?

Sanitary processes are crucial in the pharmaceutical, food and beverage industries. These industries need to procure and install the best sterile air filters Va. offers to prevent particle contamination and bacterial growth of products.

Sterile air filtration removes microorganisms, protecting ingredients, food and beverage products, packaging and equipment from microbial contamination. Effective filters reduce the likelihood of spoilage and yield loss.


The air going into a compressor carries bacteria through the system that can contaminate food products. It then concentrates these contaminants, creating higher amounts of harmful microorganisms.


Air compressors produce moisture, heat and oil, creating climates that enable many organisms to thrive. Because of this, untreated compressed air may contain many hazardous contaminants. Removing these particles is essential to protect consumers from harm.

The compressor’s mechanical actions introduce even more particles and oil aerosols. As the air cools, water vapor forms condensation, which becomes small, aerosolized droplets. This condensation also allows organisms to flourish.


It is more efficient to stop the growth of microorganisms than to eliminate them after they form. Systems must isolate contaminants as soon as possible, providing the additional benefits of lower maintenance costs and decreased likelihood of service calls.

Effective systems absorb vapor and dry the air to prohibit microbial growth.


Companies must understand which filter types are the most beneficial and how to implement them correctly.

System filtration reduces contaminants in the distribution system. Point-of-use filtration addresses all the areas where compressed air comes into contact with food. Over time, filters become clogged and dirty, compromising their integrity. It is vital to install filters in a series to ensure product sterility.

An arrangement using sterile air filtration in this way places physical barriers that help prevent the food’s microbial contamination. Putting staged filtering in place provides better protection by reducing filter overload and the need for frequent replacements.


Filters remove oil and bacteria. Bacteria inside the filters are inactive spores, but they may reactivate under certain conditions. The heat from steam sterilization of sterile air filters disables the microorganisms. Saturated steam is ideal for this filter sterilization process because it provides a constant temperature.

Strict guidelines and best-practices regarding filtration mitigate the risk of product spoilage due to contamination. The right compressors, filters and dryers are vital for the safe production of food and pharmaceuticals.

Sterile filtration is necessary to meet the purity specifications that prevent consumers from potential harm.
