    Hi,
    some RO units have 1micron filters and other 5micron, is it such a big deal or is the 5micron OK to use?

    I think the majority of RO units are sold with 5 micron sediment filters. I use the 5 micron ones.

    I've been doing a lot of reading on this lately and from what I understand, if you use a 1 micron filter then you may suffer from reduced RO output if your water from the tap is fairly low in pressure because the 1 micron is a much finer filtration reducing the rate at which water flows through it, although it may apparently help reduce clogging of the membrane thus prolonging the life of the membrane. For me I would stick with the 5 micron as my TDS is normally between 0 and 4 and to be honest, the RO output is so slow I wouldn't want to slow it down any more.
