Features to Consider When Buying a Salt-free Water Softener

There are particular features that you will want to consider when shopping for your water conditioner. These features will significantly inform your buying decision as they will determine the model that you will potentially walk home with. So what are these features?

1. Capacity

If you are buying a water conditioner then your main focus should be the resin capacity. To get the correct capacity you must find out how much water on average you would use in your home. The average amount of soft water you use in your home is dependent on the number of family members and the activities that you carry out on a normal day. When the capacity is larger the softener will regenerate less frequently.

The rating capacity of the water conditioner is done by rating the grain count, and this will vary among softeners. However, the lowest is about 16000 while the highest capacity may reach as high as 96000. The capacity can also be related to the brine tank. By knowing how hard your well water is you will be able to choose a water conditioner with the right capacity for your home.

2. Water Flow Rate

Water flow in a salt-free water softener is quite different from the traditional water softener. Besides, the salt-free water softeners doesn’t flush the filtered materials. However, the media in the water conditioner works as a catalytic media that causes crystallization of ions on the surface of the media as the water flows up continuously. As such, the system media will remain fluidized while pulling the water hardness crystals to the top of the surface.  When it comes to water flow rate, take careful consideration, the more people in your home, the higher the flow rate you will require in your water conditioner.

3. Maximum Pressure

Salt-free water Conditioners come with different maximum pressures. Check the maximum pressure of the unit you intend to buy and weigh it against the current water pressure in your home. Be sure not to take a unit that takes almost all the current water pressure. Bear in mind that salt-free water softeners will certainly decrease the pressure of water in your house. Therefore, don’t get a softener that will take up the majority of the water pressure you need in your home.

4. Chlorine Reduction

You must read the unit’s specs more carefully to see to what extend the unit filters chlorine or if it does at all. It is recommended to pick a model that fully filters if you intend to have all the chlorine filtered out of your well water. However, you must check your water and know how much chlorine it has so that you can figure out how much you want to be filtered out.

5. Softening Mechanism

Salt-free water softeners are in four different softening mechanisms. A water conditioner can come with a polyphosphate filter system, full filtering systems, electromagnetic wave filters, or magnet filters.

Polyphosphate-filtering salt-free water conditioners utilize safe chemicals – polyphosphates to coat mineral grains so that they don’t stick to the pipes or on the appliances in your home. This filtering system doesn’t remove the grains but works to reduce their effects. This filter will only catch the large elements while the small ones will easily pass through. As such, this type of filter system won’t kill bacteria or viruses nor will it remove chlorine from your water.

The full-filtering systems will soften your home water and get rid of all unwanted material in water. The system will crystallize the mineral grains as the water passes through while the additional filters for water treatment of impurities such as bacteria, viruses, and chlorine. However, you need to change the filters every 6 to 12 months depending on the water condition and usage in your home.

The electromagnetic system requires plugging into your power outlet so that it sends an electromagnetic wave through your water pipe. The waves will, in turn, magnetize the mineral grains and suspends them so that they don’t stick on any appliances. This system requires a constant power output and the water should be softer.

The magnetic systems are closely related to the electromagnetic system as it works similarly, but without electricity. Instead, a magnet is attached to the outside the pipes. However, the magnetic systems are less effective of the four but can work well when integrated with one of the first two filtration systems.

6. Construction Materials

Water softeners are constructed from different types of materials. With different studies pointing out that BPA elements found in some plastic are carcinogenic, you will want to look at the materials used to construct the unit you intend to buy more closely. Be sure to choose BPA-free plastic components and stainless steel construction in salt-free water conditioners.

7. Warranty

As in any appliance you buy to your home, be sure to check the warranty of the salt-free softeners you buy. Check what is covered and how long the warranty runs. If it is shorter, consider getting a unit with an extended warranty from either the manufacturer or the home improvement store from which you bought your unit.
