High quality filter bags and low quality filter bags have great differences in quality, durability, filtration efficiency and so on. The following filter bag manufacturers will take you to see how to identify high quality and low quality filter bags.
First of all, from the appearance point of view, high-quality filter bags are usually fine, the line seam is dense, there is no obvious damage or cracking phenomenon, and poor quality filter bags may have problems such as loose threads and irregular cutting.
Secondly, the quality of the filter bag can be preliminarily judged by touch. High-quality filter bags feel soft and have a uniform texture, while poor quality filter bags may feel rough, uneven, and even smelly.
Furthermore, the wear and stretch resistance of the filter bag can be tested by stretching it. High-quality filter bags usually have good wear resistance and tensile resistance, while poor quality filter bags may be easily torn or deformed.
In addition, the filtration efficiency of the filter bag can be tested by a simple method. Put some particulate matter into a filter bag and observe its filtering effect. High-quality filter bags can effectively filter out most of the particles, while poor quality filter bags may leak.
Finally, you can check the manufacturer, brand and certification of the filter bag. In general, the quality of filter bags produced by well-known brands and certified manufacturers is relatively high, while some small manufacturers or non-brand filter bags may have quality hazards.
In general, the identification of high-quality and low-quality filter bags requires comprehensive consideration from various aspects, from the appearance, feel, wear resistance, filtration efficiency and other aspects of inspection, while paying attention to the credibility and certification of the manufacturer and brand is also important. I hope that the above method can help you to identify high-quality filter bags and ensure the quality and performance of products.
