I bought the Typhoon III from Air Water Ice
I guess I'm making about a 100 gallons or more a month. I go through 4-6 sediment filters, one set of carbon and 2-3 DI
(refillable) each year. That's about $70.00 I think. They don't offer that exact package but make it up for me each year when I order.
Walt recommends a fiter array of:
"Get a ten micron sediment filter for your first stage, no smaller! Then obtain a good quality five micron carbon block, acid washed filter for the second stage. The ten micron filter has removed all of the dirt and sediment over ten microns from the water which protects the five micron filter. Now, all the five micron filter has to remove is sediment between 5 and 10 micron. In the third stage get a quality one micron carbon filter or a sediment filter if you have well water. You have now accomplished filtration down to one micron, five times the manufactures requirements. You have not lost a great deal of pressure and the filter can now provide you full service. So to recap; the ten protects the five, the five protects the one, and the one micron exceeds the requirement to protect the membrane by a factor of five, so your membrane sees only one micron sediment... one fifth the requirement.
Protected by a 10-to-1 micron array, the membrane is free to go about the task of removing bacteria, virus, salt, ions and dissolved metals (TDS
). The filters alone have no impact on the TDS
and should never be relied on to remove bacteria. Ions and bacteria are best left to the membrane. After the work done by the pre-filters and membrane, your water is very pure. The final stage is DI
-- A typical mixed bed DI
cartridge is capable of reducing the TDS
to zero (0). "
