The Importance Of Air Filtration
Air filters’ filtration efficiency is dependent on the size of the particles and the airflow. Higher airflows allow more particles to diffuse into the filter. This process is known as Brownian Motion.
The unit of measurement for airborne particles is micron. Particles smaller than this are less likely to cause problems, but this does not mean that they are safe from exposure. Studies show that even very small particles can affect human health. The smallest particles are removed by air filters, such as the merv 13 filter.
Mechanisms for collection
Collection mechanisms for air filtration work by intercepting airborne particles. These particles are able to stick to the filter material due to Van der Waals forces and therefore cannot move through the airstream. This effect is less important than other filtration mechanisms but is crucial for long-fibered materials. Collection mechanisms may vary depending on the particle size and velocity, but they all result in the removal of particles from the airstream.
Four main collection mechanisms are available for particulate filtration. These include inertial impaction, interception, diffusion, and electrostatic attraction. Inertial impaction occurs when a particle deviates from the airstream due to its inertia. Large particles can collide with filter fiber made of fiber when they are in the air stream. Brownnian motion causes particles to interact with filter fibers, thereby allowing them to be collected.
The MERV rating indicates the effectiveness of a filter at removing different sizes of particles. The performance of the filter is evaluated and assigned a rating. The test measures the amount of particles in the air prior to and after each test. The percentage of particles removed from the air is calculated by converting the difference between the start and end counts into a percentage. In most cases, a filter MERV 7-12 will remove airborne particles, but a MERV 13-20 filter might be needed in hospitals and general surgical wards. It can filter particles as small and as small as 10 microns.
Air filter performance is measured by the MERV rating. The higher the MERV number, the better. A higher MERV number means that the filter is more efficient at removing particles of a specific size. Most residential air filters have MERV ratings between seven and thirteen, which is the most common. These filters are highly effective in removing most airborne contaminants.
Although it may seem expensive to install air filtration equipment, it can actually prove to be beneficial. Air filtration can reduce the building’s energy consumption by 5-10%. Because more efficient filters can reduce static pressure, which means that fans require less energy to move air.
HVAC systems use thirty percent of the nation’s electricity, so energy efficiency is also important. Air filters that reduce the demand for HVAC systems can help save up to 40% of electricity. The fan curve that was developed by the system designer should be used to determine the filter selection. This can impact the blower’s energy consumption.

Maintaining a healthy indoor environment is essential for buildings. It protects occupants from harmful pollutants and improves the comfort and efficiency of buildings. Regular maintenance of your air filtration system will ensure that you have the best quality air and protect your building against harmful particles, airborne bacteria and unpleasant odors. You should also consider setting up a preventative maintenance plan. This program will include routine HVAC inspections, cleaning, and budgeting. Additionally, you should consider investing in high-quality maintenance equipment and replacement parts.
