Premier Whole Home System

Filter, soften, and drink-purify
your entire home.

One package, three systems: a whole-home filter tank that uses catalytic carbon and KDF‑55 to strip chlorine and heavy metals, a salt-based softener for hard-water minerals, and a 6-stage reverse osmosis system at the kitchen tap.

Sized for 1–4 person households. Single-tank filter setup.

What’s Included

Three systems. One installation. Every faucet covered.

Most companies sell these as add-ons. We bundle them so the water hitting your skin, your dishwasher, and your drinking glass is all treated.

Stage 1

Whole-home filter tank

Matte black Carbtrex composite tank loaded with catalytic carbon and KDF-55. Reduces chlorine, chloramines, hydrogen sulfide, heavy metals, and VOCs at the main line so every tap in the house is filtered.

Stage 2

Whole-home softener

Salt-based ion-exchange softener removes calcium and magnesium that scale your pipes, dull your hair, and shorten the life of your water heater, dishwasher, and washing machine.

Stage 3

6-stage reverse osmosis

Under-sink RO with a dedicated tap delivers up to 99% removal of dissolved contaminants — PFAS, lead, arsenic, nitrates, chromium-6 — for clean drinking and cooking water.

Inside the Tank

Catalytic carbon + KDF‑55. Most competitors don’t use either.

Tap a layer on the tank to see what it does. The media inside is what does the work — most competitors use plain GAC and stop there.

Compare The Field

Same category. Different system.

We mystery-shopped our biggest competitors. Here’s what they quoted, and what was actually inside the system they tried to sell us.

Legacy brand pricing reflects an in-home quote we received in 2026 for a comparable whole-home system, plus a separately quoted RO upsell. The cheaper competitor category publishes whole-home softener features but does not list catalytic carbon or KDF-55, and offers reverse osmosis as a separately quoted product line.

Is Premier Right For Me?

The right size matters more than the price.

An undersized tank gets exhausted quickly and leaves you with partial filtration. An oversized one is money you didn’t need to spend.
