Is the dust bag paper of the vacuum cleaner better or the non-woven fabric?

Is the dust bag paper of the vacuum cleaner better or the non-woven fabric? The filtration level is better for paper bags, but the use cost is high, and the cloth bags can be washed and used repeatedly. Paper bags are basically used abroad, but cloth bags are mostly used in China. Because there are not many customers who use vacuum cleaners in China, paper bags are not easy to buy and the prices are high. I suggest you still use a cloth bag. The former pure paper filter bag has been abandoned for a long time, and the so-called paper filter bag material is actually a kind of non-woven fabric. The small packaging hanging bags we usually see like Lipton tea are actually made of non-woven fabrics. The non-woven filter bags used in general industry are mostly made of needle punched or melt-blown non-woven fabrics. Needle-punched non-woven fabrics are suitable for coarse filtration and are mostly used in places where large particles of dust are removed, such as power plants. Meltblown non-woven filter bags are mostly used in precision environments such as medical and electronics industries. The filter bag of the vacuum cleaner should take into account his working environment, and ordinary household vacuum cleaners can use ordinary needle-punched non-woven filter bags.
