The Aiger A104 self-cleaning water filter is outstanding! Its engineering, manufacturing quality, and functionality are on par with top products from the U.S., Europe, and Israel. The components are robust, and installation was seamless—it bolted right onto my irrigation pump and worked flawlessly from the start. After a minor adjustment to the pressure sensitivity on the differential pressure switch, it adapted perfectly to my raw water conditions. A special thanks to Ms. Sarah Wang, the Aiger representative I worked with. Sarah guided me to the perfect product, answered all my questions, and followed up even after delivery and installation—a rare level of customer care. Her professionalism and dedication make her a true asset to Aiger. If you’re looking for a high-quality water filter with exceptional customer support, I highly recommend the Aiger A104. Great product, great service!
