I consider it to be a good air filter. Its negative aspect, in my opinion, is that it easily clogs up with dust and does not allow the car to breathe properly due to the oil it has. It doesn't mean that it's not a good filter, personally I recommend it for purchase, it's a good choice, it just needs regular checking and cleaning, for example, every 5000 kilometers it's good to be checked. I also believe that a good choice is the oil-free air filters, which I found are also available in the market, and they are washable too, they just have better material for filtering without needing oil to trap the dust. They definitely need checking as well, but you don't have to deal with the oiling of the filter.
