All of the AlphaNANO filters utilize the Omnifuser design technology that eliminates slotted PVC pipes in the filter. The Omnifusers allow the heavier solids to be easily purged from the bottom of the filter during backwash since they are sitting at the lowest point in the filter.

The AlphaNANO media has 50% more surface area for beneficial bacteria growth than common bead filter media.

AlphaNANO filters also feature the AlphaONE Life Support System, known as "ALISS", which keeps beneficial bacteria alive indefinitely during times of medical shutdowns, pumps failures, etc.

The 2" Clear Union Spring Check Valve located right under the 2 HP blower provides maximum flow and has built-in unions along with a PVC slide valve for extra security in case of spring check valve failure
