How to choose a suitable dust filter cartridge

When using dust removal tools, we usually know that the filter needs to be replaced after its lifespan. However, there are so many types of dust filters that choosing the right one is a complex skill. Therefore, to save you time, I've summarized some methods I commonly use. Feel free to try them out!
1. Check the materials. Before purchasing a new filter, always check the specifications on your engine. Choose a filter with suitable material, similar function, and the same material thickness to ensure compatibility between the filter and the engine.

2. Check the dust holding capacity. Different dust filters have different dust holding capacities. When purchasing, carefully check the dust holding capacity of each type and choose one that suits your needs.
3. Consider the filter's dust filtration capability. Since we're buying it to purify the air, we naturally want to choose a filter with a strong dust filtration capability. Therefore, this is another way to select a filter.

The above three methods are summarized from my personal experience. If you're unsure how to choose the right filter, feel free to save this information.
