[High-quality material] Dear friends, this is a product we have manufactured. To a longer service life, we have chosen a very fabric with a very tight fit, which can tightly wrap your filter (it is a bit difficult to put on, so please be patient while putting it on; if there are any problems, we of it first). [Protect your pool filter] The blue mesh cover protects the filter while you bathe. This increases the lifespan of the filter. Note: Don't forget to remove the protective net after using the spa. [Easy to install and clean] The mesh cover can be easily disassembled and washed at any time. The simple, stretchy fabric fits perfectly with your pool filter, making it more convenient to use.
