Drinking Water Systems

Representing only 1% of your total water bill, drinking water is probably the most important 1%. From reverse osmosis systems to carbon filtration, we provide the leading drinking water purification systems on the market today. We encourage you to look for third-party testing and look at the datasheets as you shop for drinking water systems. The longer the list, the longer the membrane life, the larger the carbon surface area, and the less you’ll have to worry about these common problems in your drinking water: Bad Odor, Foul Taste, Organic Compounds, Chlorine.

Different Drinking Water System Choices

The choice of a drinking water system is probably the most important in designing a water treatment system. From the amount of contaminants your system removes to a lower total cost of ownership, Water Doctors offers both reverse osmosis and activated carbon solutions to improve your drinking water quality.

Reverse Osmosis w/ Carbon Combination

Reverse osmosis is a membrane-based system. The membrane has very tiny pores and works by blocking anything larger than a water molecule from getting through. The system is only as effective as the membrane. So, a lower grade membrane will produce lower-quality water and need frequent replacement. This drives up the total cost of ownership.

Third-parties measure reverse osmosis quality and compile results into datasheets listing contaminants removed. The better the system, the longer the datasheet. You might find lower-end systems tested to remove 50-80% of what is in the water. Our Kinetico K5 Drinking Station has one of the longest datasheets in the industry.

Carbon Block or Activated Carbon Only

Carbon covers a wide range of filters. The lower end, typically a loose, granulated carbon, includes most of the pitcher-types and refrigerator filters. Higher grade filters feature a denser block of carbon and are more effective than granulated carbon. The Always Fresh filters that we carry are a dense carbon block, affording high levels of chlorine reduction. The density increases the contact time water has with the filter, removing more volatile organic chemicals like herbicides and pesticides.

The Always Fresh filter also has a silver-based substance that curbs microbial growth. While the main benefit to using carbon is its incredible surface area, that’s also a lot of nooks and crannies for bacteria to grow in. Silver-impregnated filters help curb that growth, making carbon filters like the Always Fresh a healthier choice for your home.

Frequently Asked Questions

Water softeners improve the water we bathe in and clean with throughout the home. Softeners are not purifiers and will not reduce a wide range of potential contaminants. Many consumers want to purify their water for drinking, cooking, and ice cubes. Our drinking water systems provide high quality, chemical-free water right at the faucet.

What’s more important to you, the water that goes “on you” or the water that goes “in you?” Most people would answer that the water they consume is more important. That’s why most people that choose to purchase water treatment equipment further refine their drinking water with a separate system.

A water conditioner is typically placed at the point where the water enters the home so it can soften (remove dissolved hardness minerals from) all the water distributed throughout the house. That’s how a water conditioner protects your water heater, water-using appliances, plumbing, sinks, bathtubs, faucets, and other things.

A drinking water system normally services a special faucet at the kitchen sink and further treats (reduces a large number of dissolved solids in) only the water you use for drinking and food preparation. It would be a waste to refine all of the water used in the home to drinking water quality. Treating drinking water at the point of use reduces the cost of the system.

Combination systems that address both kinds of water treatment needs are available. They typically offer the two systems in one complete, compact package.

Studies have found that minerals in your drinking water essentially make no contribution to your health and may even be present in forms your body can’t absorb. Unfortunately, the myth that drinking water with minerals is healthy is perpetuated by companies that promote “mineral water”. In fact, the Water Quality Association, the trade association of the water treatment industry, prohibits health claims in any of its members’ literature and advertising.

The Kinetico K5 Drinking Water Station is customizable to your home’s specific filtration needs and can actually add minerals back to your water to restore alkalinity.

For more information about the water you drink, contact your local water authority. Each year they are required to produce a report on what’s in the water in your area.

Drinking water generally contracts lead from plumbing that has been connected with lead solder (outlawed in 1986) or from outdated water distribution lines. There are a number of things you can do to reduce the risk of lead in your drinking water.

Some sources suggest running your tap water for a couple of minutes before filling a glass to flush any accumulated lead from the water line (lead dissolves into standing water over time). This isn’t a foolproof solution, however, since there is no way of knowing whether all of the lead has been removed and since lead can still dissolve into running water.

Never use hot tap water to prepare drinks or meals. Hot water attracts more lead than cold water does. If you need hot water, heat cold tap water on the stove or in a microwave.

In their informational brochure “Living Lead Free,” the American Water Works Association recommends having your water tested for lead to find out whether you should take action. Your local Kinetico water expert can have your water analyzed by a laboratory and help you decipher the results.

Use a carbon drinking water filter or reverse osmosis system that has been certified to protect your drinking water from lead. Check that the manufacturer’s claims have been verified by the Water Quality Association or NSF International; not all systems are certified for lead reduction.

Bottled water is an acceptable alternative if you would like better tasting water for drinking and cooking, but it can be expensive, a hassle to carry from the store, can contain harmful BPA chemicals and other bacteria, not to mention all those plastic bottles in our landfills.

It’s generally much less expensive in the long run to use a home drinking water system. Drinking water systems are convenient and provide you with high quality, environmentally-friendly water in your own home when you want it, at prices per gallon that are considerably lower than bottled water.

Check to see that the system you choose is certified to protect you from a wide variety of contaminants and that the manufacturer’s claims have been verified by the Water Quality Association or NSF International.

Your K5 has an indicator at the top of the unit that will slowly drop with use. This gives you an early warning that it’s time to order new filters. Once the filters have maxed out their usable lifespan, you’ll notice a loss of pressure as your K5 slows to a trickle and shuts down. We suggest purchasing shelf-stable replacement filters once the system indicator is below the halfway point–that way, you have them on hand and don’t have to scramble to find filters while guests are arriving for a dinner party. You can even change the filters yourself with our easy-to-follow  Kinetico RO Filter Change Instructions.

  1. Turn off the main valve to the drinking system and the valve to the tank. If unsure, it’s best to turn off any valves connected to the system by following the tubing. Now depressurize your system of all air and water by opening the RO faucet. There should be no water running out of the tap/faucet.
  2. Remove the old filter. This will be yellow or purple.
  3. Fill the new filter with water. This will replace the pre-filter (yellow or purple filter) that was just removed
  4. Remove and replace post-filter (orange or blue filter). This will be under the blue indicator/meter.
    *Remove and replace any K5 auxiliary filters, if applicable. DO NOT REMOVE the membrane filter (green sticker), usually located in the middle.
  5. Slowly turn the water supply back on to the drinking system and tank.
  6. Turn on water and let it run until the tank is empty.
  7. Allow unit to refill with water for at least 2 hours before using.

Step Beyond Green to Healthy Logo

Our Healthy Approach to Water

At Water Doctors, we understand that a healthy approach doesn’t always align with traditional “green” methods. While green practices often focus on environmental sustainability, a healthy approach prioritizes individual well-being, which sometimes requires different considerations. For example, many people are sensitive to certain smells, chemicals, or materials without even realizing it—these sensitivities can significantly impact their health and comfort at home.

As members of Step Beyond Green to Healthy, we are dedicated to creating safer, healthier indoor environments by educating both contractors and the public. Our team undergoes regular training to ensure we are equipped to address a wide range of health concerns. If a customer reaches out with specific sensitivities or worries, we are ready to guide them toward the best solutions.

During installation, we take every precaution to minimize potential health risks. This includes unpacking our equipment in our warehouse to allow any off-gassing to occur before the products enter your home, thus reducing exposure to potentially harmful chemicals. We also adapt our installation methods to accommodate individual sensitivities, whether that means using alternative materials, ensuring proper ventilation, or adjusting our practices to suit each customer’s unique needs.

This commitment to personalized care is one of the many reasons why Water Doctors is the best choice in water treatment. We go above and beyond to ensure not only the quality of your water but also the safety and health of your living environment. By focusing on what’s best for you and your family, we deliver solutions that truly enhance your home’s overall well-being.
