Philips AC1711/10 Filter Unavailable for a Year: Request for Supply or Compensation

Two years ago I bought a Philips AC1711/10 air purifier for about ₺9,000. The device worked very well until the filter was full, but when I wanted to buy a new filter, I realized that it is impossible to find a replacement filter anywhere. It is not available in any store or online. When I contacted customer service, they told me that the filter is out of stock. I have been waiting for about a year and there is still no stock information or solution. Because there is no original filter and I do not want to use non-original and unsafe filters, this expensive device has become completely unusable and is practically like garbage. I expect Philips to urgently supply original filters for the AC1711/10 model, put them back in stock and make them available in places where we can easily purchase them. If Philips is unable or unwilling to produce and supply these filters anymore, I also request that my grievance be resolved with an appropriate solution such as refund, product replacement, or another fair compensation, so that I am not left with an unusable device despite the high price I paid.
