R.O. Question - advice needed

[Meaty24]

I need to buy sediment replacement cartridges for my R.O. unit. I live in Manhattan and have a lot of rust in the water. How many microns do I buy? 1 mic. or 5 mic.?

Also, because the cartridges get clogged pretty quickly, it reduces my pressure in the unit. Does that fact effect my decision what cartridge to buy?

If you only have one sediment cartridge, I would get a 1 micron cartridge. If you have two, I'd get one 5 micron and one 1 micron. The sediment cartridges are cheap enough to replace as often as needed. It's not like the expense of an RO membrane or even DI resin.

You may want to try adding a second line filter before the RO unit this may help reduce the cloggen and even give you better presser and water quality.

What are you using the water for?If my water was that dirty i would add a carbon filter as well .Home depot have them.+1 masterswimmer.

I use the water for everything. Just old pipes. My R.O. has 4 chambers. I use two sediment cartridges, one carbon and one resin cartridge. Also it has a membrane

He just means that you can add another canister to accomodate another sediment filter. Most RO/DI canisters are 10" and can be added to your existing system. It's very easy to do.

Having two sidiment filters in your case is a good idea - 5 mic followed by 1 micron. If any of the prefilters clogs, as you mentioned you'll see the pressure reaching the membrane drop, and the performance of the membrane will decrease as well.
