Im not exactly sure, but I think that the 10 micron filter has finer holes in it to pull out smaller material and the 1 micron has bigger holes to pull out larger ones.

Sorry about the other post, but it is true. fishfreak just has it backwards. A micron is one millionth of a meter. The symbol for micron is the Greek lowercase mu, which is the µ symbol, same as the symbol for micro. The micron is actually an abbreviation for the micrometer (µm), and is actually recommended you use micrometer instead of micron. So a 10 micron filter filters out anything larger than 10 µm, and a 1 micron filter will filter out anything larger than 1 µm.

so which one will u guys suggest for the ro system???? and willl this change cause the water to come out slower with a 10 micron than a 1 micron

If you have a big enough RO unit to hold both of them and 2 carbon filters then that would be awesome. But I would just use a 1 mircon sediment filter, a precarbon filter and a carbon filter.

I have a relatively small, inexpensive RO syatem. (no DI) Almost all of them, mine for example, pass the water through a 5 or 10 "micron" filter, and then a 1 "micron" filter, before it gets to the RO membrane. Even after removing the sediment in the water down to that size, my filter goes through more than 50 gallons of water to produce about 13 gallons of RO. Then there's a carbon post filter used to remove any undesirable taste and any residual organics.
You could use just a 1 "micron" filter, but you"ll have to replace it more often. If you use just a 5 0r 10, that's a lot more water that will flow past the RO membrane, and down your drain.
Bottom line is, even the cheap ones work. You just have to do the maintenance. No matter how much you pay, you still, eventually have to replace the pre and post filters (I do every six months) and the RO membrane and post filter. (once a year). Won't mention where I got mine, but I "saved big money" at a local big box home improvement store.
