I am on city water (not to bad but not that good)i also have hard water
would filtering my water through a pur filter designed for household use take any of the hard water elements out and even make it anything close to ro water.
i dont have the money to put into an ro filter at this time does anyone have any suggestions on how to make such a filter to atleast take some of the crap out?

pur water filters really only remove chlorine, and odors through a activated carbon filter. they do not soften the water, they do not purify or remove bacteria the way that RO or DI would do...

Please also tell why you think a particular system is best?

Multi-Pure's RO is very good. Their filters are NSF-certified to remove a wider varieties of contaminants than most brands. It's a little on the high end but you will get what you pay for. Most filters need to be replaced every 3 to 6 months but Multi-Pure filters last up to 12 months.

It's very important that whatever filter brands you buy is NSF-certified.

You can use discount code 421896-disc when you call them or if you order online at http://www.multipureco.com. I think they also have a special promotion now till the end of the month.

*In some cases RO water is required for DM water plant.

*The membranes used for reverse osmosis have a dense barrier layer in the polymer matrix where most separation occurs. In most cases the membrane is designed to allow only water to pass through this dense layer while preventing the passage of solutes (such as salt ions). This process requires that a high pressure be exerted on the high concentration side of the membrane, usually 2–17 bar (30–250 psi) for fresh and brackish water, and 40–70 bar (600–1000 psi) for seawater, which has around 24 bar (350 psi) natural osmotic pressure which must be overcome.
-RO water is water without chemicals and has very few dissolved solids. It tastes good, keeps your plumbing in good shape, and eliminates the spots and coatings on your shower wall, sinks, toilet and faucets. Your hot water tank and anode will last longer (no chemicals or dissolved solids to attack these parts). Used in third world countries membranes eliminate bacteria and some viruses. The RO systems are usually easier to maintain than water softening units.

This is a two-chamber, under-sink, Reverse Osmosis water filtration system that is under a year old. The two water filters and the water bladder were replaced by the service agent only 3 months ago. Out of nowhere, the amount of filtered water this system generated started slowing to a crawl to where it is not very useful and we are having to buy bottled water in the interim which defeats the purpose of having a home water filtration system.

I know the filters have to be replaced periodically but we have run on previous filters for a lot longer than 3 months in the past with no interruption or slow down of water flow. Running too long on the same filter will degrade the water taste and quality, but thus far, it has never slowed the water output or flow.

Besides calling the service agent to come charge a premium and try to sell us overpriced water filters we may not need, I am availing Yahoo! Answers in hope someone may have a different idea as to what might be going on here. I've checked the turn valves and all seem to be in the fully open position. There is just not enough production of filtered water now. Could it be a clog? Or is this what NORMALLY happens when it is time to change the filters?

It's possible the current filters got fouled somehow. Take the filter info to your nearest home improvement store and buy the filters yourself. It really is an easy fix for someone with a brain...just don't let your husband do it (*grins*)
