5-in-1 Water Test Strips

Before you pick a filter, it helps to know what's actually coming out of your tap. These strips give you a quick, at-home snapshot of chlorine, hardness, pH, and alkalinity so you can match your water setup to the right solution.

How it works

Each strip has five separate reagent pads that react with your water and change color within seconds, giving you a real reading of free and total chlorine, water hardness, pH, and alkalinity all at once. Comparing the results to the color chart tells you plainly whether your water is heavily chlorinated, hard, or both, so you can choose the right filter for your actual water instead of guessing, and confirm afterward whether chlorine levels dropped once it's installed.

Good to know

• Tests 5 key markers: free chlorine, total chlorine, hardness (calcium/magnesium), pH, and total alkalinity, so you know what's actually in your tap or shower water
• Dip and read in under a minute: no meters, batteries, or lab kit required, just match the pad colors to the included chart
• Helps you decide if a chlorine-reducing shower filter fits your water, or if a separate softener is needed for hardness (strips detect hardness, but a carbon or KDF filter alone won't remove it)
• One tube covers roughly 50 tests, so you can check different taps, before-and-after a filter install, or water at a new address
• Store the cap on tightly in a dry spot; strips can lose accuracy if left exposed to humidity for long periods
