Advantages of Air Filter

Enhanced Air Quality

Air filters work by trapping dirt, dust, and other particles that are breathed in. These particles can cause respiratory problems, especially for children and the elderly. By removing these particles from the air, an air filter can help to improve the quality of air that is breathed in.

Improve equipment performance

Air filters can also help to improve the performance of a computer or other electronic equipment. They can remove harmful gases and particles from the air, which can help to protect the equipment from damage.

Galvanized Steel Frame Synthetic Bag Filter

Improve the indoor environment

Air filters can help to improve the indoor environment. They can remove harmful chemicals and particles from the air, which can reduce the amount of pollen that is breathed in.

HVAC protection

Over time, dirt, dust and debris can build up on the components of your HVAC system. Air filters prevent this accumulation by trapping particles before they reach the furnace, coils, blower and ductwork.

Types of Air Filter

HEPA Filters
High-efficiency particulate air filters can remove many airborne allergens and pollutants, including mold spores and dust. HEPA filters have a MERV rating of around 16 and are able to provide the highest protection for your home. They can even remove the smallest airborne particles, including tobacco and bacteria.

UV Filters
UV filters use short-wave ultraviolet light to kill bacteria and viruses. The UV lamps disinfect the air as it passes through the HVAC unit with germicidal radiation. These are excellent for killing microorganisms that could potentially harm your health, like mold spores.

Fiberglass Air Filters
Fiberglass air filters are the most basic air filters and have low-efficiency ratings. This type of filter has a flat-panel design and is made of layers of fibers that trap large particles such as dust, lint, and pollen.

Pleated Filters
Pleated filters have a MERV rating between 5 and 13. Materials used to make up these filters are polyester or cotton folds. They can effectively filter dust and other airborne pollutants but provide low air filtration and are less resistant to airflow. The pleats in these filters increase the filter’s surface area for better filtering.

Electrostatic Filters
Electrostatic filters use small cotton and paper fibers to create static that acts as a magnet for dust and other airborne particles. The magnetism is strong enough to keep these particles from spreading through your home, which makes them one of the best options for those needing a filter that can fight allergens.

Washable Filters
Washable air filters are environmentally friendly and a way to save money. The initial price of these air filters for HVAC systems is usually high; however, it should be viewed as an investment that will last you many years.

Media Filters
Media filters can provide more benefits for HVAC systems than standard filters with high MERV ratings. These provide the same level of filtration as a high-MERV filter but with negative consequences or airflow or static pressure. Media filters have a greater surface area, which prevents static pressure while providing better filtration.

Application Of Air Filter

Automotive

Air filters are required for many of the processes in the production of automobiles, including HEPA air filtration for paint application, fluid filtration for coatings, solvents, oils and deionised water, and molecular filtration for breathing air supply and VOC abatement.

Bio-Parmaceutical

Bio-pharmaceutical research and manufacturing involves the maintenance of sterile environments to eliminate exposure of products to viable and non-viable contamination. Air filtration plays an important role in this growing industry.

Microelectronics

The manufacture of microelectronic devices, including microchips and LCD displays, requires extremely clean environments for successful research and development and for manufacturing commercial products. The use of ULPA filters and chemical filters is common in this industry.

Museums

Air filtration, including particulate and molecular or chemical filtration, plays an important role in the conservation of museum artifacts. Contaminants in the air can deteriorate the materials which compose items in the collections.

HVAC Systems

Air filters in HVAC systems remove dust, pet dander, and other airborne particles, improving indoor air quality.

Food and Beverage

Air filters are used in food and beverage processing facilities to remove airborne contaminants and maintain product quality.

Air filter filtration process

Air Intake

When your heating or cooling system turns on, it pulls air through the intake vents. This air travels through the HVAC unit and over the air filter.

Particle Trapping

As the air moves through the filter's fibrous material, particles like dust, pollen, and pet dander are trapped within its fibers. The denser the filter, the smaller the particles it can capture. Some high-efficiency filters can even trap bacteria and viruses.

Clean Air Output

After passing through the filter, the clean air continues through the system, eventually being blown out of the vents into your living spaces. This process helps maintain cleaner air inside your home and reduces the amount of dust and allergens that accumulate.

Pay attention to details during installation of air filters

When installing an air filter, you need to pay attention to details, mainly paying attention to the following aspects：

Before installing an air filter, the components and installation environment must be cleaned so that the equipment can be installed in a clean environment. This will also make the equipment very clean and free of floating dust after installation.

When installing an air filter, pay attention to the direction of the components. There should be no errors in the direction of the components. For example, the arrows on the outer frame should be consistent with the direction of the air flow, and the direction of the filter paper creases should be perpendicular to the ground. This can avoid equipment failure. Leakage, deformation, damage, etc. may occur.

After the installation is completed, the equipment should be inspected. At this time, it is necessary to see whether the air filter can operate normally and whether there are any abnormalities during operation. In addition, it is also necessary to pay attention to various values of the equipment and check various resistances. and whether the pressure value is within the normal range.

A: We are pleased to offer you our samples,but the freight should be paid on your side.

Q: How often should I change my air filter?

A: Generally, you should change your HVAC air filter every 3 months (90 days), but this can vary depending on factors like filter type, household conditions, and the presence of pets or allergies.

Q: What is the purpose of an air filter?

A: The primary purpose of an air filter is to remove airborne contaminants like dust, dirt, pollen, and other particles from the air, improving air quality and protecting sensitive components from damage.

Q: Which is better, fiberglass or pleated air filter?

A: While fiberglass filters work, pleated filters do an overall better job at filtering and trapping common small airborne pollutants and contaminates. Pleated filters also have a longer service life (up to 90 days) and have a higher dust holding capacity.

Q: What is the best MERV rating for air filters?

A: For most homes, a MERV rating between 8 and 13 strikes the perfect balance between filtration, airflow, and cost. A MERV 11 filter, for instance, can last up to six months and offers excellent air cleaning without putting too much strain on your HVAC system.

Q: What are the components of an air filter?

A: Filter media are the core component of air filters, tasked with trapping unwanted particles and preventing their recirculation in the air. They typically consist of a synthetic fiber or mesh material with fine or microscopic perforations, and are held within a frame that is installed in the air filter system.

Q: What are the raw materials for air filter?

A: Air filters are typically made from materials such as fiberglass, pleated paper, or woven synthetic fibers. Air filters are used in applications where air quality is important, particularly in house/building ventilation systems and in engines.

Q: What is the mechanism of air filter?

A: The main filtration mechanisms in air and gas filtration include direct interception or size exclusion, inertial impaction, diffusional interception, and electrostatic attraction. The combination of all of these mechanisms enable contaminant removal in air filtration.
