Reverse Osmosis Filtration Offers Clean Drinking Water in Your Houston Home

Does your Houston water have foul smells, bad taste, or harmful impurities? Remove them with advanced RO water filtration that delivers the best-tasting water you can get.

Tap water across the country as well as across our metropolitan Houston area has been known to exhibit noticeable taste and odor.  Areas that draw from surface water sources are more susceptible to their water’s taste being affected by agricultural runoff and pollution.  

Know Your Houston Drinking Water

Surface water, as mentioned above, can be highly susceptible to contaminants because it is exposed to the open air.  Some of these contaminants, like minerals that can be in your water, can cause your water to be harder than you would like it to be. This can cause your water to have a metallic taste and smell to it that will affect the beverages that you’re making with it.  This is only exacerbated by the effects that agricultural runoff and pollution.  Whether you’re cooking, baking, making coffee, or making other beverages, this taste can seep into the taste of your favorite beverages.

Frequently Asked Questions about Culligan Reverse Osmosis Systems


I have heard a lot about Chromium 6 in drinking water in the news. What is Chromium 6 and can Culligan equipment filter out Chromium 6?

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 six.

  1. What is Reverse Osmosis (R.O.)?

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.

  1. Is Reverse Osmosis water really as good as bottled?

Yes - The 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".

  1. I already have a filter in my refrigerator. Why do I need anything else?

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.
