What are the filters in AHU? & Their Types

Air Handling Units (AHUs), essential for indoor air quality and air distribution, play a pivotal role. Here, we will explore AHUs’ filter importance, emphasizing the significance of AHU Manufacturer Company filters in removing particles and contaminants from incoming air, ensuring a healthy and comfortable environment.

Importance of Filters in AHUs:

Filters in AHUs serve as a barrier between the outside air and the indoor space. They prevent the entry of airborne particles such as dust, pollen, allergens, bacteria, and viruses, ensuring that the air circulated indoors is clean and free from harmful contaminants. Proper filtration is particularly crucial in environments where occupants may have respiratory sensitivities or allergies.

Different Types of Filters:

Mechanical Filters:

Mechanical filters, also known as particulate filters, are among the most common types used in AHUs. They work by capturing particles as air passes through the filter media. Their Minimum Efficiency Reporting Value (MERV) rating determines the efficiency of mechanical filters. Higher MERV ratings indicate better filtration efficiency. Mechanical filters are effective in removing larger particles but may have limitations in capturing smaller particles like microorganisms.

High-Efficiency Particulate Air (HEPA) Filters:

HEPA filters excel in capturing particles as tiny as 0.3 micrometers, making them vital in critical environments like hospitals, labs, and clean rooms. Exceptional at eliminating allergens, fine particles, and some bacteria and viruses.

Activated Carbon Filters:

Activated carbon filters target odors, gasses, and VOCs, adsorbing them onto the filter’s surface. Ideal for spaces with cooking odors, tobacco smoke, or chemical emissions, they enhance indoor air quality.

Electrostatic Filters:

Electrostatic filters employ charges to attract and trap airborne particles, existing as passive or active variants. Passive electrostatic filters have a permanent Charge, while active filters use an electric field to generate a Charge. These filters are effective in capturing particles of various sizes, including smaller ones.

Ultraviolet (UV) Filters:

UV filters use ultraviolet light to sterilize and neutralize microorganisms like bacteria, viruses, and mold spores, often combined with other filters for thorough air purification. UV filters are particularly beneficial in healthcare settings and areas where microbial contamination is a concern.

Pleated Filters:

Due to its folded form, pleated filters provide a higher surface area, improving particle collection and enhancing airflow. They are often utilized in residential and commercial settings and come in different MERV grades.

Bag Filters:

Bag filters consist of synthetic fiber bags that capture particles as air flows through them. They have a higher holding capacity and are suitable for areas with high dust levels. Industrial environments and larger HVAC systems utilize bag filters.

Electronic Air Cleaners:

Electronic air cleaners use an electronic charge to trap particles. They can be effective in capturing both larger and smaller particles. These cleaners require regular maintenance to ensure consistent performance.
