Simple, straightforward and low shipping rates for these reverse osmosis system parts.
Q. "From your experience, do you have any installation tips?"
A. With any brand of RO system that has a carbon filter ahead of the membrane, we recommend that you disconnect the membrane and run the water through the carbon filter initially for at least five to ten minutes. Most carbon filters will dump some carbon at first and this can foul your membrane. Do this whenever you replace the carbon filter as well and you will save yourself some potential grief.
Q. "While I am buying an RO system from you should I order an extra membrane and carbon filters?"
A. Most people will not mention this (or do not know) but RO membranes have a shelf life. We highly recommend that you buy your RO membranes right before installing them and not to purchase extras until you need them. We take pride in offering not only today's replacement cartridges/membranes but we also offer replacements for RO units that we used to sell.
Q. "I have a 'standard' RO unit and I need parts. Will yours fit?"
A. There really isn't any such thing as a 'standard' Reverse Osmosis unit. If you purchased your RO from us, we currently have the filters and replacement cartridges for all of the types and brands that we have sold. Just let us know the model number and we will know what parts that you will need. If you did not purchase the reverse osmosis unit from us, we cannot furnish you with membranes or filters for your RO system (exceptions are H20 Works / KISS / Drinking Water Solutions brand and Culligan® brand).
Q. "How often should I replace my filters and membrane?"
A. This is a very common (and difficult to answer) question. It depends a lot on your water conditions, water quality and your usage. We believe that in no case (no matter what brand that you have) should you keep the filters longer than a year (changing them every six months is better) nor the actual RO membranes longer than two years (changing once per year is better of course).
Q. "I originally purchased my RO elsewhere and now need filters and a membrane for it. I believe that your filters and membrane will fit. If I order them and they don't fit can I return them?
A. Before you place an order, let us know that you did not purchase your RO from us and along with that, send us all the information that you have about your RO. Also, please read our return policy page.
Q. "How do I know which post filter to choose? The KISS-2400010 or the KISS-2400010-QC?
A. The KISS-2400010 post filter has 1/4" female iron pipe threads on the inlet and the outlet. You can take the fittings off of your old post filter and reuse them in the new filter. The KISS-2400010-QC post filter has Quick Connect fittings built-in to the filter housing. Simply push 1/4" O.D. plastic or copper tubing directly into the fitting for a quick and easy leak proof connection.
Q. "I have an Aristrocrat 4000, but I heard that there might have been multiple configurations. How do I know which filters I need?"
A. The Aristocrat 4000 reverse osmosis systems were sold in two different styles. Both styles used the 30GPD replacement RO Membrane #KISS-1990154-1.
One style had two vertical housings, and two horizontal. One of the horizontal filters was the RO membrane itself and the other one was a post polishing filter. The first vertical cannister used the KISS-2400001 sediment pre-filter. The second vertical cannister used the KISS-2400024 carbon pre-filter. The horizontal post polishing filter was the KISS-2400010.
The other style had three vertical housings and then only one horizontal filter which was the RO membrane. The first vertical cannister used the KISS-2400001 sediment pre-filter. The second vertical cannister used the KISS-2400024 carbon pre-filter. The third vertical cannister used the KISS-2400999 carbon pre-filter.
