I bought this filter to replace their standing filter as I couldn't get a simple replacement part (connector hose). I was recently looking to purchase some replacement filters and found that they are no longer in stock and there is no indication that they will be back in stock. What good is a filter system if you can't buy replacement filters? Beware of buying anything from ESOW as they are totally unreliable and DO NOT endorse their products. I've read in several questions that there is another filter that could be used, but examining two showed a completely different structure with no data to support the use of that filter. I think if you don't mind buying a new device every three months, then this is your company.
