See & Feel the Difference

Cleaner Water, End to End

Why Homeowners Love It

Whole-House Chlorine Removal

The QRS removes chlorine taste and smell across your entire home and reduces VOCs. The difference is sensory and immediate:

No more "pool smell" in showers — less skin irritation
Noticeably cleaner water taste at every faucet
Laundry lasts longer without chlorine wearing down fabrics

Protects Plumbing & Appliances

Chlorine dries out rubber seals, degrades gaskets, and corrodes internal components in water heaters, dishwashers, and washing machines.

The QRS removes chlorine before it reaches your pipes, extending appliance lifespan and saving you thousands in replacement costs.

Engineered to Last

A tank-within-a-tank design sets the QRS apart from big-box filters:

Outer tank: fiberglass wound for structural strength
Inner tank: food-grade plastic keeps water pure
Premium carbon media delivers consistent filtration year after year

Better With Other Systems

The QRS shines as part of a complete setup:

QRS + EC5 Softener: chlorine removal protects softener resin
QRS + Ultrefiner RO: cleaner feed water means longer RO cartridge life
The full stack outperforms any single system alone

Questions?

Frequently Asked Questions

What exactly does the QRS remove from water?

The QRS reduces chlorine, chloramines, THMs, HAAs, and VOCs (volatile organic compounds like atrazine, benzene, and toluene). It also uses KDF-55 media to reduce lead, mercury, and other heavy metals — all before water reaches any tap in your home.

Is the QRS NSF certified?

Yes. The QRS meets NSF/ANSI 42 (chlorine taste & odor reduction) and NSF/ANSI 53 (VOC and chemical contaminant reduction) standards. Lead reduction is achieved through KDF-55 heavy metal media. These are third-party certifications you can trust.

How do I know if my water needs this system?

That's exactly why we offer a free, EPA-certified in-home water test. It takes about 30 minutes and shows you exactly what's in your water. No obligation, no sales pitch. Just facts.

Can I pair the QRS with other systems?

Absolutely. The QRS handles chemicals and lead, but it works best alongside a water softener (for hardness) and a drinking water RO system (for additional purity). Many customers benefit from the complete pairing: QRS + EC5 Softener + Ultrefiner RO.

How often does the filter need replacing?

Filter lifespan depends on your water quality and household water usage. Our team determines this during your free water test and initial consultation. We also offer maintenance reminders so you're never caught off guard.

Is the QRS the right system for me?

The QRS is perfect if: you have city water with chlorine, care about taste and smell, want whole-house coverage, or have sensitive skin. It's not the best choice if: you're on well water with iron or sulfur, only care about drinking water (use RO instead), or are strictly price-shopping. The free water test will tell you exactly what you need.

What if I'm on well water?

The QRS is specifically designed for municipal/city water with chlorine. If you're on a well with iron, sulfur, or sediment, the QRS won't address those issues. Schedule your free water test and we'll recommend the right system based on your well water analysis.
