Reverse Osmosis Systems
in Warren, MI

Yes. Reverse osmosis is one of the most effective point-of-use treatments for lead, and Culligan reverse osmosis systems are certified to reduce it. In Warren, that matters most for homes on one of the 17,500 service lines still listed as unknown material, or homes with older faucets and solder. If you are unsure about your line, check the city’s inventory and schedule a free in-home water test from Culligan.

Reverse osmosis is among the most effective home treatments for PFAS. Warren’s most recent report lists PFOA at up to 2 ppt, under Michigan’s 8 ppt limit and the 4 ppt federal limit, and no other PFAS compounds are listed. Michigan also limits PFOS to 16 ppt and PFHxS to 51 ppt. An under-sink RO system adds a layer of protection for the water your family drinks.

Yes, chromium six (or hexavalent chromium) has recently been discovered in limited amounts in some water supplies. Chromium six is suspected of being a carcinogen, and should not be ingested at amounts above the federally mandated limits.  We have never been alarmists, but if you are concerned about the quality of the water you drink, you might want to consider a reverse osmosis system.  Reverse Osmosis is the only readily available system that removes up to 97% of Chromium-6. You can read more about it here.

Reverse osmosis is a sophisticated multi-stage filtration system that is capable of removing up to 97% of all the dissolved minerals from your water.  It is designed to make water that is at least as good as the water you buy in bottles.  Many times, it’s even better.  This reduces waste in landfills by using less bottled water, making reverse osmosis environmentally friendly.

Yes – The Culligan RO system uses multiple processes including Reverse Osmosis to make great tasting, low sodium drinking water. Reverse Osmosis removes about 97% of the TDS (Total Dissolved Solids) including salt and sodium from the water. Read the labels on bottled water and you will discover reverse osmosis is the same process used by most bottlers … so in effect … you really are getting … “bottled water without the bottle”.

Yes. Reverse osmosis reduces fluoride along with other dissolved minerals. Fluoride is added during GLWA treatment, and Warren’s report shows a highest regulated result of 0.49 ppm, well under the 4 ppm limit. If you would rather keep fluoride in your drinking water, your Culligan expert can walk you through the options.

Yes. Total trihalomethanes and HAA5 form when chlorine reacts with natural organic matter, and Warren’s highest running averages were 50 ppb and 20 ppb, both within their limits. The carbon stages in a Culligan RO system, together with the membrane, reduce these byproducts along with chlorine taste and odor at the kitchen tap.

Refrigerator filters are typically just carbon, and while carbon filtered water is better than no treatment at all, it is limited in what it can remove. Only reverse osmosis is capable of removing dissolved minerals and chemicals from your water.
