If you live in Phoenix, you already know the desert climate brings some unique challenges—relentless heat, low humidity, and extremely hard water. But there’s another concern that doesn’t always get as much attention: what’s actually in your tap water?
From chlorine taste to high mineral content, many Phoenix residents are turning to filtration and purification systems to improve their water quality. In this blog, we’ll break down the top benefits of water purification systems for Phoenix homes—and why they’re more of a necessity than a luxury in the Valley of the Sun.
What Is a Water Purification System?
A water purification system is designed to remove unwanted contaminants from your tap water—right before it reaches your glass, pot, or coffee maker. Depending on the system, it can reduce or remove:
-
Chlorine and chloramines
-
Sediment and sand
-
Volatile organic compounds (VOCs)
-
Heavy metals like lead or arsenic
-
Pesticides and industrial runoff
-
Bad odors and aftertastes
Common water purification systems include:
These systems are typically installed under the sink to treat water for drinking and cooking—though when paired with a whole-home water softener, they become part of a powerful, comprehensive solution for your entire household.
Why Phoenix Water Needs Extra Attention
Phoenix sources most of its water from the Salt, Verde, and Colorado Rivers, and although it’s treated to meet federal safety standards, it still carries a heavy mineral load and often contains chlorine and other additives.
Here’s why water purification is so important in Phoenix:
1. Water Hardness Is Extreme
Phoenix has some of the hardest water in the country, regularly measuring above 250 parts per million (ppm). While a water softener can help prevent scale buildup, it doesn’t filter out contaminants—that’s where purification systems step in.
2. Chlorine Taste and Smell
The City of Phoenix uses chlorine and other disinfectants to kill bacteria and viruses. While that’s necessary for safety, it often leaves behind a strong taste and odor that many people find unpleasant. A purification system removes those residual chemicals for better-tasting water.
3. Desert Infrastructure and Distribution
Long water transport pipelines and high evaporation rates mean Phoenix water often picks up more sediment and trace contaminants along the way. Purification systems help protect your family from anything your water may pick up between the treatment plant and your kitchen.
The Benefits of Water Purification Systems in Phoenix
So what are the actual benefits of water purification systems in the Phoenix area? Whether you live in North Scottsdale, Arcadia, or the East Valley, these advantages are hard to ignore:
1. Better-Tasting Water
Phoenix residents often complain about the taste and smell of their tap water. The culprit? Chlorine and high mineral content.
Point-of-use purification systems—like reverse osmosis or dual-stage filters—remove the chemicals and impurities that cause that flat, metallic, or chlorinated taste. The result is crisp, clean water you’ll actually want to drink.
2. Protection from Contaminants
Even treated water can contain trace amounts of:
One of the most important benefits of water purification systems is peace of mind. You know your drinking and cooking water is being filtered at the last stop before it reaches you.
3. Reduced Skin and Scalp Irritation
While softeners help reduce dryness caused by hard water, purification can make a big difference too—especially for people with sensitive skin or allergies. Removing chlorine and other irritants from your drinking and food prep water reduces your body’s daily chemical exposure.
4. Big Savings vs. Bottled Water
Many Phoenix families rely on bottled water for drinking—but those bottles come with a high cost (and plenty of plastic waste). A purification system gives you clean water straight from your tap, saving hundreds per year and keeping your recycling bin a lot lighter.
5. Cleaner Cooking and Beverages
Coffee, tea, pasta, rice, soups—it all starts with water. One of the less obvious benefits of water purification systems is how much better your food and drinks will taste when they’re made with clean, filtered water.
6. Convenience
No more hauling 5-gallon jugs from the store or running out of bottled water in the middle of a meal. With a purification system under your sink, clean water is always on hand—right where you need it most.
7. Safer Water for Kids and Pets
If you’ve got little ones at home (or furry ones), water purification is one of the easiest ways to reduce exposure to chlorine, sediment, and trace chemicals. Babies, kids, and pets all benefit from cleaner, more consistent hydration.
Types of Water Purification Systems for Phoenix Homes
Here are the main types of point-of-use systems we recommend for Phoenix residents:
Reverse Osmosis (RO)
RO systems force water through a semipermeable membrane, filtering out up to 99% of dissolved solids and contaminants. They’re typically installed under the sink and provide purified water via a dedicated tap.
Perfect for drinking, cooking, filling ice trays, or rinsing produce.
Single-Stage Filtration Systems
Simple but effective, single-stage filters use one cartridge—often carbon or sediment—to remove chlorine, odors, and particulates. Great for improving taste and clarity at a specific tap.
Dual-Stage Filtration Systems
Dual-stage systems combine two types of filtration—typically sediment and carbon—to target a broader range of contaminants. They’re an ideal solution for households that want better-tasting, cleaner water without the complexity of reverse osmosis.
Why You Still Need a Water Softener
A water purification system handles contaminants—but not hardness.
Phoenix’s extremely hard water causes scale buildup in pipes, damages appliances, and reduces efficiency in water heaters and dishwashers. That’s why the most effective solution is a two-part system:
-
A water softener to remove calcium and magnesium
-
A point-of-use purification system for clean, great-tasting water where you need it
Together, they deliver complete protection and peace of mind.
Choosing the Right System for Your Home
Your ideal system depends on:
-
The number of people in your household
-
How much water you use daily
-
Your water quality goals (taste, safety, appearance)
-
Your current plumbing and available space
