They sell a filter that you HAVE buy another part to use the filter. It's like buying a car with 3 wheels and then they tell you that you have to buy the fourth tire. Its a really *** cheap way to do business. I hope the company pays for it. I know i will never buy another thing from intex and i will let everyone i talk to not to buy from intex or in your *** is what they should be called. User's recommendation: Don't use intex EVER.
