中国香港采购需求：更换过滤器，更换滤芯，更换水过滤器，更换过滤器

I need to replace the water filters under my sink, but I'm not sure if the model I currently have is still in production. It would be great if you could confirm the availability of similar filters or recommend alternatives. Please reach out to me via WeChat so I can share pictures of my existing filters. This will help us determine the best replacement options and ensure everything fits properly. Looking forward to your prompt response!
