A North Star Water Softener can help you get rid of all your hard water problems by removing the minerals and salt that cause water hardness.

The saltwater-based water softening process replaces the hard water ions with soft water ions. After this process, the water is ideal for use in the house and it doesn’t cause any issues that are associated with hard water.

Our North Star water softener reviews are going to discuss the features, specifications, and other important information for 5 of their best models.

How to Choose the Best North Star Water Softener for Your Needs

Simply choosing any North Star water softener for your home or office might not give you the most efficient results. Most North Star water softener reviews neglect to mention the fact that every household has a different type of water and varying consumption requirements as well.

Buyers need to understand certain facts and choose the water softener model that best suits their needs. Here are some of the facts that you should keep in mind while looking for a North Star water softener.

Water Hardness in Your House

Water hardness is determined by grain rating. This rating tells you the number of grains of minerals present in one gallon of water. If you buy a water softener with higher grain capacity, it will likely cost more, but it will reduce your expenses on salt and water. This is because it will need to flush the filtering material with salt water less frequently.

Flow Rate of the Water Softener

The flow rate is the gallons of water supplied by a water softener per minute. As the softener takes time to treat the water, the flow coming from the supply line slows down as it enters the softener. To make sure that your softener doesn’t lower your water pressure too much, aim at buying a water softener with flow rate of at least 2 gallons of water per minute for each family member.

Additional Considerations for Water Softeners

Keep in mind that certain areas have special water conditions that require additional features in the water softener. Most cities add chlorine and chloramines to the water to kill bacteria, but this can lead to dry hair and rough skin. If you have well water, you might have too much iron, sulfur, or manganese. You could also have herbicides and pesticides in your water. In such cases, you’ll need to buy a water softener specifically designed to filter these materials, or a separate filter.
