Reviews
Water Conditioners are systems designed to address minimally hard water, which occurs when there’s a concentration of minerals in tap water. Find out if you need one and how to make the best choice for your home.
What is a Water Conditioner?
A water conditioner is a system that addresses hard water by binding to minerals and altering their chemical structure to render them harmless. These systems may also be known as descalers or salt-free conditioners. The term salt-free is used because water conditioners operate without using salt, which is required by their softener counterparts.
Water conditioners are designed to address minimally hard water, which occurs when there’s a concentration of minerals in tap water. The high mineral content of hard water leads to several issues including:
- Damage to plumbing and appliances
- Residue on dishes
- Fading, stains, and damage to clothes
- Dries out hair and skin
What Does a Water Conditioner Do?
Water conditioners alter the chemical structure of minerals in hard water so that they can no longer stick to things and form scale build-up. Conditioners do this by using a process called template-assisted crystallization (TAC). Water conditioners have TAC media that water must pas through, and when it does — the minerals react and form harmless, nanometer-sized crystals. So instead of hard water minerals binding to your plumbing to form scale, they bind to each other to form these crystals. The crystals are completely harmless ant you won’t be able to see or feel them.

Water Conditioners vs. Water Softeners
Water softeners and water conditioners both aim to address hard water, but there are a few differences between these types of systems.
The primary difference between water softeners and conditioners is how they work. Water softeners remove hard water minerals through ion exchange — which replaces hard water ions with salt. Water conditioners don’t remove hard water minerals, these systems alter the chemical structure of the minerals to render them harmless.
Typically, water conditioners can only tackle minimally hard water. If your home has very hard water, you will likely need to use a water softener.
Another major difference between water softeners and conditioners is maintenance. Water softeners require frequent salt bag replacements to continue working, along with electricity that can increase your utility bill. By comparison, water conditioners have neither of these requirements, which makes them a low-maintenance and eco-friendly alternative.

How To Read Your Water Quality Report
Just because your tap water looks and tastes fine doesn’t mean it is. Sometimes, tap water contains chemicals and impurities that could harm you and cause problems to your appliances.
Bottled Water vs Filtered Tap Water: Important Facts
Americans consume around 1,500 disposable plastic water bottles each second, or nearly 2.2 million each day. Many Americans place a high trust in bottled water, and assume it’s safer than tap water. The truth is there are virtually no real benefits to consuming bottled water. Most bottled water is little more than over-priced tap water in a bottle that contributes to over 2 million tons of plastic waste in our landfills every year.
Comparing Water Filter Technology
Depending on the type of water filter you’re interested in, you may be able to choose from a range of different water filter technologies including mechanical, activated carbon, reverse osmosis, ion exchange, and ultraviolet light filtration. With so many options to choose from, it’s important to understand these filter technologies to determine which option is best suited for your needs. To assist you with the buying process, we’ll explain how each of them work.
Why Do I Need a Water Filter?
Just because your tap water looks and tastes fine doesn’t mean it is. Sometimes, tap water contains chemicals and impurities that could harm you and cause problems to your appliances. Yes, it happens. We’re not saying this applies to all homes but in many cases, unfiltered tap water just isn’t safe enough.
