HEPA Filters
How HEPA filters work in air purifiers
HEPA filters, or High Efficiency Particulate Air filters, are designed to trap and remove microscopic particles from the air. These filters work by using a dense mesh of fibers that can capture particles as small as 0.3 microns in size, including dust, pollen, pet dander, and even some bacteria and viruses. The air is forced through the filter, and as it passes through, the particles become trapped in the fibers whilst clean air is released back into the room.
HEPA filters operate on the principle of mechanical filtration, meaning that they physically block and capture particles rather than relying on chemical reactions. This makes them highly effective in removing airborne allergens and pollutants, making the air cleaner and healthier to breathe.

Electrostatic Precipitators
Electrostatic precipitators are highly efficient devices used in HVAC systems to clean the air and remove various psections such as smoke and dust. By utilizing the principles of electrostatics, these precipitators ensure cleaner and healthier indoor environments.
1. How Electrostatic Precipitators Clean the Air in HVAC Systems
Electrostatic precipitators function by creating an electrostatic field that charges the psections present in the air. This charged air is then passed through collector plates with opposite charges, causing the psections to be attracted and adhere to these plates. The cleaned air is then released back into the environment, ensuring improved air quality.
2. Removing Smoke, Dust, and Other Psections with Electrostatic Precipitators
One of the key benefits of electrostatic precipitators is their ability to effectively remove smoke, dust, and other harmful psections from the air. The charged psections are trapped on the collector plates, preventing them from being released back into the surroundings. This is particularly important in areas where air pollution is a concern, as electrostatic precipitators can significantly reduce the presence of these harmful substances.
Electrostatic precipitators offer several advantages over traditional air filtration systems. They have a high efficiency rate, removing up to 99% of psections from the air. Additionally, they are low maintenance, as the collected psections can be easily cleaned off the collector plates. This makes electrostatic precipitators a cost-effective and environmentally friendly solution for improving indoor air quality.
