Ask a Question
  • I just installed AF-9500-M, display shows 1500 gallons, I understood it must show 4000, what should I do?

    1500 gallons is correct, you don't need to do anything. The number 4000 in image is in liters and is just for demo purpose.

Great filter and wonderful company

The filter is excellent and it produces clean, clear water that is absolutely tasteless (which, of course, is a good thing). The company is great, too. I order online, take care of payment (which is less than Amazon), and within a week I have my filter. Easy to install and get 3 months of clean water. Order without concern - good product and good company.
