Air filter meshes can be classified based on their application areas and filtration efficiency. Common classification standards include: Primary Efficiency Filter Mesh (G1-G4), Intermediate Efficiency Filter Mesh (M5-M6), High Efficiency Filter Mesh (H10-H14), and Ultra-High Efficiency Filter Mesh (U15-U17). By selecting the appropriate grade of filter mesh, air quality can be effectively improved to meet the needs of different application scenarios. TMN will provide a series of introductions around the classification standards of air filter meshes, so follow along to gain a deeper understanding.

Air Filter Mesh Classification Standards

Primary Efficiency Air Filters: These filters must capture particles of 5μm and above with an efficiency of 40-60% (G1-G4 grades, based on the EN779 standard). They are commonly used as primary filters in industrial and commercial air conditioning systems and can also be used as pre-filters for medium efficiency filter meshes. Their main function is to remove larger dust and particles. Filters of this grade can generally use metal materials (stainless steel, aluminum, galvanized steel) as the filter mesh surface. These metal filter meshes are corrosion-resistant, have high mechanical strength and durability, and are lightweight, easy to clean, and reusable.

Medium Efficiency Air Filters: These filters must capture particles between 1-5μm with an efficiency of 60-95% (M5-M6 grades, based on the EN779 standard). They are suitable for environments with certain air quality requirements and can also be used as pre-filters for high-efficiency filter meshes, mainly removing smaller dust and particles to extend the lifespan of high-efficiency filters. This grade of filter can use metal materials (stainless steel, aluminum, galvanized steel) for the filter mesh surface, or materials like polypropylene that offer good filtration efficiency and durability.

High Efficiency Air Filters: These filters must capture particles of 0.3μm and above with an efficiency of 99.97% and above (H13-H14 grades, based on the EN standard). They are primarily used in clean rooms, operating rooms, and other places with extremely high air quality requirements. This grade of filter generally does not use metal mesh unless the manufacturing process can achieve the required high filtration precision. Therefore, high-efficiency and even ultra-high efficiency filters more commonly use materials like fiberglass, PTFE, and ultra-fine synthetic fibers to ensure their high filtration performance.

Ultra-High Efficiency Air Filters: These filters must capture particles of 0.1μm and above with an efficiency of 99.% and above (U15-U17 grades, based on the EN standard). They are mainly used in ultra-clean environments such as dust-free workshops and pharmaceutical factories.

The above is an explanation of the classification standards and applications of air filter meshes. However, in special environments like the medical industry, in addition to requiring high-efficiency or higher-level air filters, there are more stringent additional requirements for the filter mesh. Let’s quickly and briefly explore these requirements together.

Medical Grade Air Filter Mesh

A medical grade air filter mesh is a high-efficiency filtration device specifically designed for medical environments to ensure clean and safe air. It is typically made from biocompatible materials such as high-quality stainless steel, titanium, fiberglass, PTFE, and ultra-fine synthetic fibers, which can effectively remove particles, bacteria, viruses, and other contaminants from the air. These filter meshes are commonly used in operating rooms, intensive care units, laboratories, and other medical settings with extremely high air quality requirements to prevent airborne infections and contamination.

Hospitals are critical places for patients to recover and receive treatment, but they are also high-risk areas where germs and contaminants can easily spread. Therefore, high-quality medical grade air filter meshes are of great importance for hospitals.

What qualifies as a high-quality medical grade air filter mesh?

High Filtration Performance: Medical grade filter meshes must effectively filter out particles, bacteria, viruses, and other microorganisms from the air, typically achieving HEPA or ULPA standards.

High Filtration Efficiency: For particles of 0.3 microns and above, the filtration efficiency generally needs to reach 99.97% or higher.

Low Air Resistance: While ensuring high filtration efficiency, medical grade filter meshes must also maintain low air resistance to ensure smooth airflow and effective air circulation.

Durability: Medical grade filter meshes must have a long lifespan, ensuring they can maintain high performance over extended use.

Compliance with Industry Standards: They must meet or exceed relevant international and national standards, such as ISO , EN, ASHRAE 52.2, etc.

Non-Toxic and Chemical-Free: The materials used must be non-toxic and harmless, and after processing, they must be thoroughly cleaned to ensure no chemical residues remain, ensuring the safety of medical personnel and patients.

These standards and requirements ensure that medical grade filter meshes can provide continuous, efficient, and safe filtration protection in demanding medical environments.

Wire Mesh Filters: What You Need To Know Before You Buy

Woven wire mesh is arguably one of the most versatile materials in the world, as it can be formed to accommodate almost any filtration or design application. With other materials, such as wedge wire, on the market, woven wire mesh stands out as it balances performance with cost-savings.

But as no one operation is the same, buying customized wire mesh screens and filters proves to be ideal in most cases. With that, it is important that you know what to expect when building a customized wire mesh part so optimal results are achieved.

Having gained over 150 years of woven wire mesh experience, W.S. Tyler is here to ensure you put the ideal solution for your process in place.

That said, this article will help you better understand:

What is needed to build the best possible solution

Building the Perfect Mesh Specification

There are several specifications that must be methodically determined while designing the ideal custom mesh screen/filter. Of these specifications layer configuration, size and shape, and mesh count can be the hardest to determine.

Single- vs. Multi-Layer

There are several reasons why a multilayer configuration would be best for your operation. Of these reasons, the biggest deciding factor would be the need for strength and durability.

Let’s say you are filtering a substance or screening a material that has various particle sizes. If you were to simply use a single layer of fine mesh, odds are it wouldn't hold up as the larger particles would compromise the integrity of the mesh in a short period of time.

To combat this, you would take the fine mesh needed to deliver the filtering capabilities and sandwich it between layers of stronger, more coarse mesh. Doing so will prevent the larger particles from damaging the finer filter layer.

That said, if you are filtering non-abrasive material or seeking to obtain the filter cake, a single-layer configuration will best suit your needs.

Size and Shape

When working with woven wire mesh, in particular, the sky's the limit when it comes to the ways it can be formed to accommodate your operation. That said, there are a few aspects to the forming process that simply can’t be done.

When forming deep drawn funnel screens for low-pressure die casting, for example, there is a ratio, based on the screen’s diameter, that limits the depth in which the screen can be drawn. This ratio essentially limits the depth measurement from exceeding the measurement of the diameter of the screen.

Putting this into perspective, if you require a screen that is one inch in diameter, it would be impossible to draw the part out to a measurement of 5 inches.

Mesh Opening Size

The mesh opening size that best suits your operation ultimately depends on the particles you are working with.

If you are screening large pieces of aggregate you will want to use larger mesh openings as they will allow the large particles to pass while also accommodating the wire diameter needed to create a durable screen. On the other hand, if you are filtering out sand from raw oil, a finer mesh count will be needed as these particles can prove to be small.

With that, the mesh count of the screen may be limited based on the type of woven wire cloth. Square mesh has a mesh count range of 4 mesh down to 230 mesh whereas filter cloth has a mesh count range of 4 microns to 302 microns.

Important Information for Wire Mesh Inquiries

When trying to identify the wire mesh needs of a customer, there is a “Good, Better, Best” scale that is used. With that, there are three primary mesh elements that dictate how effective the mesh supplier is at helping you establish the perfect mesh solution:

What Does the Buying Process Look Like?

Regardless of the needs of your wire mesh part, the buying process starts with reaching out to the mesh supplier with an overview of the mesh to see if it can be produced. Typically, you will be asked to submit some sort of drawing or blueprint with the mesh specifications so an engineer can review them.

Read the article below for an in-depth breakdown of what you should expect when submitting a wire mesh drawing:

If neither a blueprint or drawing is available, our team of experts can work with you to determine which specifications will work best for your needs.

Once the engineer confirms that the desired mesh specification can be produced, you will receive a quote reflecting the cost of the materials needed to produce the mesh. With that, it is important that you know the different elements of the desired mesh specification.

This includes:

The mesh count
The alloy of the mesh
Any sort of heat treatment needed
Any value-added services needed

Once you receive the quote, the final step would be to accept it and submit a purchase order. Taking all this into consideration, the biggest obstacle you will face during the buying process is if the mesh can be produced.
