Exploring Air Filtration Methods

Air filtration is a process of filtering the air in a room or a patient’s respiratory system. This can be done using a variety of methods, including: inertial impingement, bridging, complete blocking, and straining. The most effective air filter in the market is the 16x25x1 air filter merv 13.

Straining

Straining air filtration is an alternative method of removing particles from the air. This method is effective for large particles because it speeds up the flow of air. Particles that are too heavy can’t keep up with the flow and are forced to leave the airstream. Straining is similar in function to impaction but it is designed to capture smaller particles. This involves using a web of fibers strategically placed to increase the inertia. This forces the particles onto the fibers and captures them.

Complete blocking

Complete blocking of air filtration can be achieved in two ways. A bridging action is when particles of smaller pore sizes form cakes. This is made possible by higher concentrations of particles at the feed. Second, complete blocking is facilitated by the presence of particles with larger pore sizes.

Mesh made of stainless steel

A stainless steel mesh air filter is a great choice for filtration. It is durable and can filter nearly 100% of bacteria from air. It is also a versatile option with a wide range of applications.

Pleated filters

Pleated air filters offer many benefits and are a great choice if you’re looking to improve your air filter efficiency. They have a larger surface area which allows them to capture more particles, and a higher airflow efficiency. Additionally, they don’t require any special installation methods and slide right into the same spots that a standard flat filter would.

Aluminium air filters

Light-duty commercial aluminum mesh filter are an efficient and economical way to clean the air and reduce pollutants. These filters can be used for rooftop HVAC systems and grease filtration. They are easy to clean and can last for many years. Many filters come with an integrated economizer that opens and closes mechanically.

Cotton gauze

For dusty conditions, cotton gauze filters are a great choice. They are more restrictive than foam filters, but they have the advantage of being more convenient. They are made with a metal meshing that is pleated with cotton fibres. They also maximise surface area, meaning more filtration.
