    I purchased a Spectrapure MaxCap for my new house. I'm moving at the end of the month, so I don't have it up and running yet.

    I'm just wondering how often, on average, I will have to swap out the filters. I have the flush kit for the RO resin.

    I'm just looking for a ballpark estimate. I live in Canada, and it's much cheaper for me to have the replacement filters shipped to a PO box I keep in Niagara Falls, NY. As a result, I need to plan ahead a bit more than if I just had them delivered to my house.

    Also, do any of the filters have a "shelf life" if they aren't actually in use? If not, I may just order more than one at a time and store them at home.

    If the DI filters are sealed, their shelf life should be just about forever. The same should go for carbon prefilters. RO and micron filters should have an indefinite shelf life regardless.

    DI resin even vacuum sealed has a shelf life of about 6 months before it begins to degrade.
    Spectrapure RO membranes unlike most others are tested then packed and shipped wetted in a proprietary solution. They must stay wet at all times or they can go bad. You might contact Spectrapure and ask the shelf life of the membrane before stocking up on something that may not be good when you need it. They are a Sponsor here on 3Reef and have a forum here for just that purpose.

    As AZDRat says, DI and membranes should not be kept more than 6 months to be sure of their freshness. Sediment and carbon filters have an indefinite shelf life.

    It is hard to estimate the life of prefilters, as I don't know how much dirt you have in your water. Likewise with DIs, I don't know how much TDS is coming out of the membrane and/or how much CO2 there may be in the water. What I can say is that the MaxCap/SilicaBuster combo lasts longer than any other DI you could use. If you make a LOT of water, you might be needing a new MaxCap cartridge within six months. I'd prpbably have a sediment, carbon and MaxCap on hand until you've got a handle on how long they will last for your water conditions.
