Clean water for every tap in your home

SHIELD whole-home filtration removes lead, PFAS, chloramine, and other proven health hazards - independently certified, professionally installed, always working.

Why Shield?

The water problem is real

Your family deserves to know what they're drinking.

Most municipal water leaves the treatment plant clean. However, lead service lines, aging pipes, and chemical residuals can affect what actually comes out of your tap. The facts are sobering, but SHIELD has you covered.

Why Shield?

What SHIELD protects against

Whole-home protection, from every source.

Lead & Heavy Metals

✓ NSF/ANSI 53 certified · PALADIN

SHIELD PALADIN removes soluble and particulate lead from your water supply before it reaches any tap, shower, or appliance in your home. No level of lead is safe for children.

PFAS/PFOA/PFOS
(Forever Chemicals)

✓ NSF/ANSI 473 certified · PALADIN

SHIELD PALADIN removes forever chemicals from nonstick cookware, food packaging, and stain-resistant products. They don't break down in the environment or your body.

Chlorine & Chloramine

✓ >99.95% reduction · GUARDIAN & PALADIN

Added by utilities to kill bacteria, chlorine and chloramine affect taste, odor, and health - especially through shower inhalation. SHIELD removes both at the water entry point.

Scale & Corrosion Control

✓ NSF 60 certified · SCALE CONTROL

SHIELD SCALE CONTROL inhibits calcium carbonate scale formation and protects your pipes, water heater, and appliances with a protective phosphate layer.

Infrastructure Protection

Protect your plumbing from the inside out.

Scale buildup costs homeowners thousands in appliance damage and reduced heating efficiency. SHIELD SCALE CONTROL uses Active Armour technology to stop scale before it forms.

Important: SHIELD SCALE CONTROL controls scale formation. It does not soften water. Calcium and magnesium remain in solution. This product is not a water softener.

SCALE PREVENTION

Stops scale before it forms

Inhibits the ability of calcium carbonate to crystallize and bond to pipe walls, heating elements, and appliance surfaces.

CORROSION PROTECTION

Nano-layer pipe protection

A protective phosphate film coats pipe interiors and metallic fixtures, inhibiting oxidative corrosion throughout the plumbing system.

Not a softener

No salt. No sodium. No waste.

Minerals stay in solution - where they should be. No salt regeneration, no sodium discharge, no maintenance chemicals required.
