What Is a Whole House Water Filter?
A whole house water filter is a filtration system installed at the point where water enters your home — the main supply line. Unlike under-sink or pitcher filters that treat water at a single faucet, a whole house system treats every drop of water that flows through your plumbing. Here is exactly what it covers:
- Coverage: Every faucet, shower, appliance, and outdoor spigot in your home
- Flow rate: 10-25 gallons per minute (GPM), depending on system size
- Installation: Requires professional plumbing at the main water entry point
- Space needed: 2-3 feet of wall space near the water heater or utility room
- Filtration stages: Typically 1-5 stages, from sediment pre-filter to carbon block
For Orlando homeowners, a whole house water filter is the first line of defense against the chlorine, sediment, and contaminants in municipal and well water. It protects your plumbing, improves your skin and hair health during showers, and ensures filtered water for dishwashing, laundry, and cooking.
How It Works
Here is the step-by-step process of how a whole house water filter works:
Step 1: Water enters the home. Municipal or well water flows through the main supply line into your home.
Step 2: Sediment pre-filter catches particles. A spun or pleated polypropylene filter catches sand, rust, silt, and other particles larger than 5-20 microns. This protects downstream filters and extends their lifespan.
Step 3: Carbon block removes chlorine. Water passes through a compressed activated carbon block, which adsorbs chlorine, VOCs, and organic contaminants. The carbon converts chlorine to harmless chloride ions and water.
Step 4: Filtered water flows to every fixture. Clean, filtered water flows through your plumbing to every faucet, shower, and appliance in your home.
What It Removes
Here is what a whole house carbon block filter removes from Orlando water:
| Contaminant | Removal Rate | Why It Matters |
| Chlorine | 95-99% | Causes dry skin, hair damage, pipe corrosion |
| Sediment | 90%+ | Causes staining, cloudy water, appliance damage |
| Taste/Odor | 95-99% | Makes water taste metallic, earthy, or "off" |
| VOCs | 95-99% | Industrial chemicals that may be present in water |
| Pesticides | 90-95% | Agricultural runoff that may contaminate groundwater |
| Hardness minerals | 0% | Does NOT remove calcium/magnesium — need a water softener |
Where It's Installed
Whole house water filters are installed at the main water entry point — typically in the garage, utility room, or a dedicated equipment closet. Installation requires:
- 2-3 feet of wall space near the water heater or main water entry point
- Access to a drain for flushing the filter
- Proximity to the main supply line where water enters the home
- 40-80 PSI water pressure (ideal for Orlando municipal water)
- Professional plumbing and an Orlando building permit ($50-150)
Professional installation takes 2-4 hours and costs $200-400 for labor. The system itself ranges from $400-2,000 depending on the type and stage count. Total installed cost: $600-2,400.
Bottom line: A whole house water filter treats every drop of water entering your home, removing chlorine, sediment, and contaminants from all faucets and showers. For most Orlando homes, a multi-stage carbon block system like the Aqua Home Water 5-Stage at $800-1,200 installed provides the best balance of contaminant removal, flow rate, and value. Sediment pre-filters alone ($200-400) are insufficient for Orlando's chloramine-treated water. Get a free water test to determine your exact contaminant profile before choosing a system.

What does a whole house water filter remove?
A whole house carbon block filter removes 95-99% of chlorine, reduces taste and odor, and catches sediment, rust, and other particles. Multi-stage systems can also remove VOCs, pesticides, and some heavy metals. A whole house filter does NOT remove hard water minerals (calcium, magnesium) — for that you need a water softener.

How much does a whole house water filter cost in Orlando?
A quality whole house water filter in Orlando costs $800-2,500 installed, including the system, professional installation, and permit. Budget single-stage systems start at $650-1,250. Multi-stage systems with sediment pre-filter and carbon block cost $1,150-2,650. Annual maintenance is $150-400 for filter replacements.
How often do I need to replace a whole house water filter?
In Orlando, replace carbon block filters every 6-12 months and sediment pre-filters every 3-6 months. Higher chlorine or sediment levels may require more frequent changes. Signs of a clogged filter include reduced water pressure, chlorine odor returning, and off-taste in water. Set a calendar reminder to replace filters every 6 months for optimal performance.
