Compared with the conventional PP melt-blown filter element, which is installed in the water purifier through a threaded structure, the operation is more complicated, and the PP melt-blown filter element is easily damaged during installation, which is not conducive to the installation of the PP melt-blown filter element. The PP melt-blown filter element that is easy to install has a simple structure, can quickly fix the filter element, and install the filter element inside the water purifier.

[0018] Compared with the prior art, this PP melt-blown filter element which is easy to install has a silicone sheet and a filter element. When in use, the outer surface of the silicone sheet is tightly fitted with the upper and lower end surfaces of the filter element. The silicone sheet has a certain elasticity and can prevent water from overflowing from the gap between the two after being deformed under pressure, making it easier for the filter element to filter the water.
