What Is Air Filter Cotton and How Does It Work?
Air filter cotton is a specialized fibrous material designed to trap airborne particles and contaminants while allowing air to flow through HVAC systems, air purifiers, and vehicle engines. It works through mechanical filtration, where the cotton fibers create a maze-like structure that captures dust, pollen, and other particles as air passes through.
Material Properties
Air filter cotton is made to catch dust and dirt from the air. This cotton has special features that help it work well for filtration. The table below shows what makes air filter cotton different:
Property | Description |
|---|---|
Density | Changes how heavy and effective the filter is. |
Tensile Strength | Shows how strong the filter is and if it tears easily. |
Hygroscopic Capacity | Lets the cotton soak up water, which helps it filter better. |
Acid and Alkaline Resistance | Helps the filter last longer in tough places. |
Thermal Resistance | Stops the filter from breaking down in high heat. |
Filtration Efficiency | The cotton fibers are shaped to catch more dust and dirt. |
Air filter cotton uses fibers that are spread out evenly. This makes it easier for air to move through. The cotton can hold a lot of dust before you need to clean it. Some filters use cotton gauze, which gives more space to trap dirt. This helps the filter work better without blocking the air.
Tip: Air filter cotton is strong and bends easily, so you can wash and use it again. This saves money over time.
Common Uses
