Electrostatic filter cotton and meltblown filter cotton can both be used in the production of air filters, as they are both raw materials for air filters. So, what is the difference between them? Here, we will explain the differences between electrostatic filter cotton and meltblown filter cotton.
When discussing electrostatic filter cotton, we must first talk about static adsorption: When a small, non-electrostatic object approaches an electrostatic object, the closer end will be induced with the opposite electric charge to the electrostatic object due to the electrostatic induction phenomenon, causing it to be attracted and stuck to the electrostatic object.
Electrostatic filter cotton is a filter cotton that uses the principle of static adsorption. Compared to traditional mechanical filters, the filtering efficiency of static filter cotton is higher, and it can better adsorb ultra-fine dust. If an air filter uses electrostatic filter cotton, it not only has higher filtering efficiency, but also has better resistance, making breathing smoother and dust capacity higher. Integrating this electrostatic filter material into the air filter fabric significantly boosts the overall performance of air filtration systems.
Meltblown non-woven fabric is made up of fine, shorter fibers. The uniformity of the meltblown non-woven fabric is good, and it feels particularly soft. This type of meltblown nonwoven polypropylene fabric has good filtering performance and liquid absorption.
Meltblown Filter Cotton is one type of non-woven fabric product. Its raw materials are often made of polypropylene (PP material) pellets. The process of producing meltblown non-woven fabric is the following: polymer feeding, melting extrusion, fiber formation, fiber cooling, network formation, and then solidifying into fabric. Because it has the appearance and some of the properties of fabric, it is called "meltblown fabric."
When selecting the appropriate air filter fabric material, consider the filter’s environment, the particles you need to capture, and the desired air quality. For areas prone to pollution or with high levels of fine particulate matter, electrostatic filter cotton might be the preferred choice due to its enhanced ability to capture microscopic particles. In contrast, in settings where microbial contamination is a concern, meltblown filter cotton could offer better protection due to its effective microbial filtration capabilities. Whether to use electrostatic filter cotton or meltblown filter cotton in an air filter depends on your own needs, or you can tell our sales team about your requirements and the environment you plan to use it in, so they can develop a solution for you.
