Purchased in November 2024. Both the filter and pre-filter fabric parts were replaced around June. However, there is a lot of fraying on the fabric parts. I recommend replacing them after purchase, along with the filter. I will delete any questions regarding specifications as I do not know the answers. I will also delete questions about things written in the product description or stock of other products. If you live on a remote island, please consult in the question section beforehand. Also, recently there have been many people who do not confirm receipt, so I will only sell to those who can confirm receipt on the day they receive the item. Please understand this when purchasing. Please refrain from purchasing if you are overly concerned about details. I will be lowering the price gradually, so please purchase when you are ready. I will delete any price negotiations. Thank you for your understanding.
