Types Of Air Filtration Devices


There are many types of air filter devices, such as the merv 13 filter. These include Permanent media, Pleated filters and Electronic filters. These filters work by removing airborne particles by means of force of attraction. The smaller particles that make up the airborne dust are attracted to larger media fibres. These particles become stuck between the media fibers. This creates an irregular path that increases the chances of particles colliding with the media fibres.

Inertial impingement

Inertial impingement in air filtration is a separation mechanism. It captures particles according to their mass, momentum, velocity. Fluids flow in streamlines around a solid filter medium and contaminant particles will follow these streamlines. Particles can suddenly turn when they come into contact with a blockage and impact the solid filter media.

Inertial impaction can lead to particles being deposited in other parts of the airways. This is due to increased impact probability when particles are accelerated by turbulent movement. This process is particularly effective in capturing larger particles that have a large mass, velocity and momentum.

Pleated filters

Pleated air filters are generally more effective at capturing airborne contaminants than their non-pleated counterparts. This is because of their larger surface area, which allows them to trap more particles. These filters are used to improve the air quality in HVAC systems across different industries and prevent harmful air contaminants building up.

Fiberglass air filters are more affordable than pleated filters but have a shorter service life and need to be cleaned more often. Some fiber-based filters have been reinforced to improve their efficiency and reduce resistance against airflow.

Permanent media

Permanent media for air filtering can be very effective in capturing large amounts airborne dust particles. The filtration process involves forcing air to pass through the filter fibers. Particles may stick to the filter depending on their properties.

These filters can be made of a variety of materials, including nylon fibers, plastic fibers, and polyester fibres. These materials should be coated with acrylic resin binders that include an antimicrobial agent. Some filters may have a curable resin that is applied in strips along the media.

Electronic filters

Electronic filters are air cleaners that capture particles from the air. Their efficiency varies depending on the particle size. Large particles are charged to a high extent. Very small particles are also charged, but are not collected as well on the filter plates. Despite their effectiveness, electrostatic precipitators can’t filter all kinds of particles at the same time. It can also depend upon the particle size.

These air cleaners are usually installed in the HVAC system’s ductwork and provide whole-home filtering. They can remove allergens, dust particles, and other contaminants. However they must be cleaned frequently. The average life of an electronic air cleaner is two to three months.

UV filters

UV filters for air filtration have a number of benefits. First of all, they neutralize biological organisms that pass through them. This includes viruses, mold spores, and bacteria. These organisms’ DNA can be damaged because UV light is so strong. They are also highly efficient in cleaning the air inside a home.

The UV filters used for air filtration can help reduce odors, and prevent the spread of contagions. This is because they can destroy pathogens that are responsible for odors. These pollutants can cause a variety of health problems, particularly in people who have respiratory problems.
