Trying to locate replacement filters for a water filtration system on my drilled well. At the well head, there are two large filters attached to a mechanism bearing the brand name "Aqua Thin". I also have an under-sink reverse osmosis system inside my house with three-stage filters bearing the brand name "Aqua King". Original installer of this system has gone out of business. See attached photos for reference.
Here's their web-site ... perhaps if you contact them they can help find a supplier.
