How It Works: 2 Stages of Protection

2 Stages of Protection

pH Neutralizer uses NSF-certified calcite blend to raise acidic well water to a safe, neutral level, protecting plumbing, appliances, and water quality while improving taste and reducing corrosion

95%
of sediment filtered
1 point
raises the pH level
Stage 1

Sediment Filter

Captures fine dirt, sand, rust, and debris—blocking up to 95% of particulates in your water

Stage 2

Smart Metered PH Neutralizing Filter

Corrects acidic water by raising pH to safe, neutral levels, protecting plumbing, appliances, and water quality

Stage 1

Sediment Filter

Filters dirt, sand, rust and debris from entering your home

5-micron pleated design traps up to 95% of particulates

Oversized 20” filter ensures maximum capacity and maintains 
strong flow (15 GPM)

Eco-friendly: Washable and reusable. Manufactured using 
FDA approved materials

Replace every 6-12 months for best performance

Made in the USA

Why it matters:

Effectively captures dirt, sand, rust, and debris to deliver cleaner water as it moves to the next stage of carbon filtration.

Stage 2

Smart Metered PH Neutralizing Filter

Corrects acidic water by raising its pH to a neutral level, preventing corrosion, plumbing damage, and metallic tastes

Prevents corrosion of pipes, appliances, and water heaters.

Reduces leaching of metals like copper and lead into household water.

Improves water taste and quality by eliminating metallic or sour flavors.

Helps prevent blue-green staining and pinhole leaks caused by acidic water.

Why it matters:

Acidic water corrodes pipes, damages appliances, and can leach harmful metals like copper and lead into your drinking water. A pH neutralizer protects your home and provides safer, better-tasting water at every tap.

Why is it important to balance PH levels in Water?

Maintaining balanced water pH levels is essential to prevent corrosion of plumbing fixtures, pipes, and appliances and to optimize the performance of other pieces of water treatment equipment, including water softeners, catalytic carbon filters and reverse osmosis drinking water systems.

How often should I backwash the calcite filter?

A: The calcite filter should be backwashed periodically to prevent media compaction and maintain filtration efficiency. The frequency of backwashing depends on factors such as water usage and the level of contamination. You can use your Kind Water App to adjust the settings.

Will a calcite filter remove other contaminants besides adjusting pH?

No, a calcite filter primarily adjusts pH levels by neutralizing acidic water. It may not effectively remove other contaminants present in the water.

Can I install the Kind Water Smart Metered pH Neutralizing Filter myself?

Definitely! As a handy homeowner, you can easily install a Kind Water Smart Metered pH Neutralizing Filter. We provide extra fittings, extension cords, a detailed product manual, and how-to videos to help. Plus, you can call our Technical Service team 6 days a week if you run into trouble. If you are uncomfortable, you can hire a plumber or handyperson, and they’ll be able to follow our installation instructions very quickly.

How long does the calcite media typically last before it needs replacement?

The lifespan of the calcite media depends on factors such as water chemistry, pH levels, and flow rates. As it becomes depleted over time, it may need to be replenished periodically, typically every few years.

Are there any maintenance requirements for the calcite filter besides backwashing?

Besides periodic backwashing, maintenance requirements for the calcite filter may include checking and adjusting the media bed, monitoring pH levels, and replacing the media when necessary

What pH range does a calcite filter typically achieve in water?

A calcite filter typically achieves a pH range of around 7 to 8 in water, considered neutral to slightly alkaline.

Can Kind Water Smart Metered pH Neutralizing Filter be used in conjunction with other water treatment systems?

The Smart Metered pH Neutralizing Filter can be used alongside other water treatment systems, such as water softeners, carbon filters, and reverse osmosis systems, to enhance overall water quality and effectiveness.

How do I know which system to order?

You should always start with one of our Water Test. Testing the water will guarantee you are buying the correct system for your water quality problem.

The cost of your water test will be fully credited toward any system purchase.
