A whole-house water filtration system (also known as a point-of-entry system) is a comprehensive filtration system that connects directly to your main water line. Unlike single-faucet filters, a whole-home water filter treats all the water entering your home, delivering filtered water to every tap, shower, appliance and faucet in your home.
As an authorized Kinetico dealer since 1988, Southwest Water Treatment understands the unique mineral and contaminant profile of Arizona water. While local municipalities work hard to treat water to meet legal standards, impurities such as nitrates, arsenic, copper, lead and chlorine frequently linger in the supply.
Investing in a whole-home water filter provides a valuable final layer of protection at your property’s point of entry. By filtering out impurities before they reach your pipes, it helps provide better water for cooking, drinking, hygiene and household chores.

Our team strives to maintain quality water throughout Arizona. With warranty opportunities and free water testing, we’re here to help you craft your water needs with precision. We provide specialty equipment to add to your system, which can target specific contaminants in your water supply. Our experts can also serve households who gain their supply from a well water system.
As its name suggests, a whole-house water filter provides filtered water for your entire home. Also known as point-of-entry systems, this technology treats any water that enters your property. This provides you with clean water for cooking, cleaning, hygiene and hydration.
Once you select the right system for your property, a smooth setup depends on proper planning. Knowing how to prepare your home for a whole-house water filter installation helps ensure our certified technicians can complete the job quickly and efficiently.
Our installation team will need clear, unobstructed access to your home’s main water supply line and shut-off valve. Take a moment to locate this valve—usually found in a garage, utility closet, or near the exterior perimeter—and clear away any boxes, storage, or debris in the area.
A point-of-entry whole-home water filter needs to be installed in a location where it can intercept water before it branches out to your water heater or individual taps. This area should ideally be a climate-controlled space protected from freezing temperatures and direct sunlight, with access to a nearby floor drain or drain line if your specific system requires it.
Clear a pathway from the driveway or service entrance to the designated installation zone. Our team will be moving heavy, specialized filtration equipment into place, so removing obstacles in advance helps ensure a safe and seamless installation process.
A water softener is designed to remove hardness minerals such as calcium and magnesium, helping prevent scale buildup. A whole home water filter targets chemical contaminants, chlorine, sediment, iron and foul odors. For the ultimate in water quality, many Arizona homeowners choose a combined system that softens and filters simultaneously.
These systems are point-of-entry units, meaning they are installed near your main water line before the pipes split to feed your water heater or individual faucets. Common locations include garages, basements or dedicated utility closets.
When handled by the professional team at Southwest Water Treatment, most standard residential installations are completed within a few hours, minimizing any interruption to your daily routine.
