Project Source Whole House Water Filter

Ensuring Clean, Safe Water From Every Tap in Your Home

Water is life’s essential element—we drink it, cook with it, bathe in it, and clean with it. Yet many homeowners remain unaware of what’s actually flowing through their pipes. From chlorine and sediment to potentially harmful contaminants, municipal water often comes with unwanted additions. That’s where whole house water filtration becomes not just a luxury, but a necessity for health-conscious homeowners.

Today, I’m diving deep into the Project Source whole house water filter—a comprehensive solution that’s gaining popularity among homeowners seeking better water quality without breaking the bank. Having recently installed one in my own home, I’m eager to share my experiences and everything I’ve learned about this game-changing system.

Understanding Project Source Whole House Water Filters

Project Source has established itself as a trusted brand in home improvement, offering quality products at accessible price points. Their whole house water filtration systems continue this tradition, providing an effective solution for improving water quality throughout your entire home.

A Project Source whole house water filter is exactly what the name suggests—a filtration system installed at your home’s main water supply line, ensuring that every drop of water entering your home passes through the filter before reaching any faucet, shower, or appliance. Unlike point-of-use filters (like pitcher filters or faucet attachments), these systems provide comprehensive protection.

What makes these systems stand out is their balance of performance, durability, and affordability. Project Source has designed their filters to address common water quality concerns without requiring homeowners to invest in overly complex or expensive systems.

Where to Purchase a Project Source Whole House Water Filter

Finding a Project Source whole house water filter is relatively straightforward. These systems are primarily available through Lowe’s Home Improvement stores, as Project Source is one of their exclusive house brands. You can purchase these filters:

• In-store at most Lowe’s locations in the plumbing department
• Online through the Lowe’s website, with options for home delivery or in-store pickup
• Occasionally through third-party retailers like Amazon, though availability may vary

When shopping, you’ll notice several models available, ranging from basic sediment filters to more comprehensive systems with activated carbon for improved taste and odor removal. Prices typically range from $150 for entry-level systems to around $500 for more advanced models, making them significantly more affordable than many competing brands that can cost upwards of $1,000.

The Science Behind the System: How Project Source Filters Work

Understanding how these filters work helps appreciate their value. Project Source whole house water filters operate on surprisingly straightforward principles, though the engineering behind them is quite sophisticated.

The standard system consists of a housing unit that connects directly to your main water line, typically installed after your water meter but before your water heater and branch lines. Inside this housing sits the actual filter media, which varies depending on the model you choose.

The filtration process employs multiple stages to progressively remove contaminants:

1. Pre-filtration: Water first passes through a sediment filter that captures larger particles like sand, rust, and debris. This stage protects both your plumbing and the subsequent filtration stages.
2. Primary filtration: Depending on your model, this might involve activated carbon, KDF media, or other specialized filtration media. The carbon works through adsorption, chemically binding contaminants to its surface as water passes through.
3. Post-filtration: Some models include a final polishing stage to catch any remaining particles and further improve taste and clarity.

Water flows through these stages naturally, powered by your home’s water pressure, without requiring electricity or creating wastewater like reverse osmosis systems do. This passive operation contributes to the system’s efficiency and low maintenance requirements.

Contaminant Removal: What Gets Filtered Out?

One of the most crucial considerations when evaluating any water filter is understanding exactly what contaminants it removes. Project Source whole house water filters target a wide range of common water quality issues, though specific removal capabilities vary by model.

The standard systems effectively reduce:

• Sediment, sand, and rust particles (down to 5 microns in most models)
• Chlorine (typically 85-95% reduction)
• Volatile organic compounds (VOCs)
• Some heavy metals like lead and mercury (though removal percentages vary)
• Agricultural chemicals and pesticides
• Common industrial pollutants
• Microplastics

The activated carbon models are particularly effective at improving taste and odor by removing chlorine and organic compounds. However, it’s important to note that these systems are not designed to remove:

• Dissolved minerals (they don’t soften water)
• Bacteria and viruses (for microbiological filtration, additional systems are required)
• Fluoride (specialized media would be needed)

For homes with specific concerns like bacterial contamination or extremely hard water, Project Source filters work well as part of a more comprehensive water treatment strategy that might include additional specialized equipment.

Flow Rate Considerations: Will Your Showers Still Feel Strong?

A common concern with whole house filtration is potential reduction in water pressure. Project Source has addressed this by designing their systems with minimal pressure drop in mind.

Most Project Source whole house filters provide flow rates between 10-15 gallons per minute (GPM), which is sufficient for most average-sized homes. For context, a typical shower uses about 2.5 GPM, while a washing machine might use 3-5 GPM when filling.

The key factors affecting flow rate include:

• Filter size (larger housings allow higher flow rates)
• Filter media type (some restrict flow more than others)
• Filter cleanliness (as filters catch more contaminants, flow may gradually decrease)
• Your home’s existing water pressure

During my installation, I measured the pressure drop at about 5 PSI—noticeable on instruments but imperceptible in everyday use. Our showers maintained their satisfying pressure, and simultaneous water usage (like running the dishwasher while someone showered) remained problem-free.

If you have a larger home with multiple bathrooms that might be used simultaneously, consider their higher-capacity models with 1″ connections rather than the standard 3/4″ systems.

Cost Analysis: Initial Investment and Long-Term Value

The financial aspect of any home improvement deserves careful consideration. Project Source whole house water filters are positioned as a mid-range option, offering substantial value without premium pricing.

The initial investment typically falls between $150-$500 depending on the model and capacity you choose. This includes:

• Filter housing unit ($100-$300)
• Initial filter cartridge (included with housing)
• Basic installation components like mounting bracket and wrench

Additional costs to consider include:

• Installation (DIY vs. professional, discussed later)
• Replacement filters ($30-$80 each, needed every 3-6 months depending on usage and water quality)
• Any additional plumbing adaptors specific to your home’s setup

Over a five-year period, assuming quarterly filter changes for a mid-range system, the total cost of ownership would be approximately $1,000-$1,500. While not insignificant, this represents substantial savings compared to bottled water (which could easily exceed $3,000 over the same period for a family of four) or premium filtration systems from specialized water treatment companies.

The economic value becomes even more apparent when considering potential savings from:

• Extended appliance lifespan (reducing scale and sediment damage)
• Reduced cleaning product usage (filtered water cleans more effectively)
• Fewer plumbing repairs from sediment buildup
• Decreased spending on bottled water or point-of-use filters

Filter Lifespan and Replacement: Ongoing Maintenance Requirements

Understanding the maintenance requirements before purchasing helps prevent surprises down the road. Project Source designs their systems for relatively simple maintenance, though regular filter changes are essential for optimal performance.

Standard filter cartridges typically last:

• 3-6 months for a family of four with average water usage
• Potentially longer for smaller households or those with cleaner incoming water
• As little as 1-2 months for homes with particularly high sediment levels

Visual indicators that it’s time to change filters include:

• Noticeable reduction in water pressure
• Change in water taste or odor
• Visible discoloration of the filter cartridge (if using a clear housing)

Replacement filters are readily available where the systems are sold. Project Source uses standardized sizing for most models, typically 10″ or 20″ cartridges with standard diameters, making compatible filters easy to find. While Project Source branded replacements are recommended, third-party compatible cartridges are available, sometimes at lower prices.

The filter replacement process itself is straightforward, typically requiring:

1. Shutting off water to the system
2. Relieving pressure using the built-in button
3. Using the included wrench to open the housing
4. Swapping the old cartridge for a new one
5. Reassembling and checking for leaks

This entire process usually takes less than 10 minutes once you’re familiar with it—a small investment of time for continued water quality.

Installation: DIY Project or Professional Job?

One of the appealing aspects of Project Source whole house water filters is their installation-friendly design, making them suitable for confident DIY homeowners with basic plumbing experience.

The standard installation process involves:

1. Identifying the ideal location (after water meter, before water heater)
2. Shutting off main water supply
3. Cutting into the main water line
4. Installing shut-off valves before and after the filter location (if not already present)
5. Mounting the filter housing to the wall or floor joists
6. Connecting the housing to the water line using appropriate fittings
7. Installing the filter cartridge
8. Slowly restoring water flow and checking for leaks

Essential tools for installation include:

• Pipe cutter appropriate for your plumbing material
• Adjustable wrenches
• Teflon tape and pipe joint compound
• Measuring tape
• Level
• Drill with appropriate bits
• Mounting hardware

The entire process typically takes 2-3 hours for someone with moderate DIY skills. The most challenging aspect is usually making clean, straight cuts in the existing plumbing.

For those less comfortable with plumbing work, professional installation is recommended. A licensed plumber can typically complete the installation in 1-2 hours, with service costs ranging from $200-$400 depending on your location and any complications specific to your plumbing system.

Compatibility: Will It Work With Your Home’s Plumbing?

Project Source designed their filters with versatility in mind, making them compatible with most residential plumbing systems. However, there are important considerations regarding your specific setup.

These filters work well with:

• Copper piping
• PEX tubing
• CPVC plumbing
• Most municipal water supplies
• Many well water systems (though additional pre-treatment may be beneficial)

Connection sizes typically come in:

• 3/4″ NPT (standard for most residential applications)
• 1″ NPT (available for higher-flow requirements)

For homes with unusual plumbing configurations or extremely limited space near the main water line, adapters or custom installation approaches may be necessary. The systems require approximately 12-15 inches of clearance below the housing for filter changes, so vertical space constraints should be considered when planning installation.

If your home has galvanized steel pipes (common in houses built before 1960), special considerations may apply. These pipes often have internal corrosion that can break loose when the plumbing is disturbed during installation, potentially causing temporary discoloration or sediment release.

Materials and Construction Quality

The durability of any water treatment system directly affects its long-term value. Project Source has balanced affordability with quality construction in their whole house filter designs.

The standard systems feature:

• Filter housings made from food-grade polypropylene, free from BPA and other concerning chemicals
• Reinforced housings capable of handling normal water pressure (up to 100 PSI)
• Brass fittings for durability at connection points
• Stainless steel components for the mounting bracket
• Silicone O-rings for reliable sealing

Higher-end models may include clear housings for visual monitoring of filter condition or metal reinforced components for additional durability. The filtration media varies by model but typically includes NSF-certified materials designed specifically for drinking water applications.

While not as heavy-duty as some premium systems costing three times as much, the construction quality is appropriate for the price point and intended residential use. With proper installation and maintenance, these systems typically provide reliable service for 7-10 years before the housing itself might need replacement.

Maintenance Beyond Filter Changes

While filter replacement is the primary maintenance requirement, a few additional steps help ensure optimal performance and longevity:

1. Periodic housing cleaning: About once a year, clean the inside of the filter housing with mild soap and water when changing filters to prevent biofilm buildup.
2. O-ring inspection: Check the O-ring seal during each filter change, applying a thin layer of food-grade silicone grease if it appears dry.
3. Pressure monitoring: If your system includes a pressure gauge, check it occasionally to identify potential issues before they affect performance.
4. Shut-off valve exercise: Once every few months, operate the shut-off valves to ensure they don’t seize up from disuse.
5. Winter protection: For installations in unheated areas, insulate the system or take precautions against freezing in colder climates.

These simple maintenance steps require minimal time but significantly extend system life and performance.

Certifications and Standards: Is Quality Assured?

When it comes to anything affecting your water supply, certifications provide important peace of mind. Project Source whole house water filters generally comply with relevant industry standards, though specific certifications vary by model.

Key certifications to look for include:

• NSF/ANSI 42: For aesthetic effects (taste, odor, and particulates)
• NSF/ANSI 53: For health-related contaminant reduction
• NSF/ANSI 61: For material safety (ensuring components don’t leach harmful substances)

Most Project Source systems meet NSF/ANSI 42 standards, while some higher-end models also comply with NSF/ANSI 53 for specific contaminants. All components typically meet NSF/ANSI 61 material safety standards.

The filter housings are generally rated for standard residential water pressure (up to 100 PSI) and temperatures between 40-100°F. For homes with water pressure exceeding 80 PSI (which can be determined with an inexpensive pressure gauge), installation of a pressure regulator is recommended to protect both the filtration system and your home’s plumbing.

Warranty Protection

For most homeowners with municipal water supplies, Project Source offers the sweet spot of performance and value. Those with severe water quality issues or specialized concerns might benefit from more advanced systems, while those on extremely tight budgets might consider simpler sediment-only filters.

Hard Water Compatibility

While Project Source whole house water filters effectively remove many contaminants, they are not water softeners and don’t remove dissolved minerals that cause hardness. However, they can be an excellent complement to water softening systems or a first step in addressing hard water issues.

For homes with hard water, these filters:

• Remove sediment that could clog or damage water softeners
• Reduce chlorine and other chemicals that might interfere with softening processes
• Protect plumbing and appliances from particulate matter while separate systems address hardness

If hard water is your primary concern, consider installing both a Project Source filter (to handle sediment and chemical contaminants) and a dedicated water softening system (to address mineral hardness). The filter should be installed before the softener in your water flow path to protect the softening media from sediment and extend its lifespan.

For mildly hard water, some Project Source models include scale inhibition media that doesn’t remove hardness minerals but modifies their crystalline structure to reduce scale formation—a partial solution that’s better than nothing but less effective than true softening.
