Aquasure Fortitude: A Whole House Water Filter System Guide

When was the last time you thought about the water running through your home? Not just what comes out of your faucet, but every drop filling your bathtub, running through your dishwasher, or soaking into your laundry.

If your answer is “not recently,” you’re not alone. But here’s the thing: your home’s plumbing is like its bloodstream. And the right whole house water filter system is the heart that keeps it clean.

Earlier this week, we took a closer look at how even when city tap water meets federal safety standards there are still contaminants and chemicals you should filter out. The Fortitude Pro was the hero of that blog post, but what about the rest of our Fortitude line up?

Let’s break down your options and help you pick the perfect filter for your home. No fluff. No jargon. Just the facts, with a wink of wisdom.

Why Do You Need a Whole House Water Filter?

If you’ve ever seen cloudy tap water, noticed strange odors, or spotted scale buildup around your fixtures, your water's trying to tell you something.

Whether you're on city water or a private well, contaminants can sneak in:

• Sediment
• Chlorine
• Pesticides
• or even heavy metals.
• A whole house water filtration system tackles contaminants as water enters your home. That means every faucet, every appliance, and every shower benefits. You don’t have to treat water one sink at a time. Fortitude protects the whole flow.

Still wondering why you need a whole house water filter?

Here’s What One Can Do for You:

• Protect plumbing and appliances from sediment damage
• Improve water taste and smell
• Reduce chlorine, VOCs, and chemical runoff
• Cut down on scale and rust stains
• Filter out organic matter, sand, and silt
  

So what should you look for in a system? Let’s dive into the Fortitude lineup and match the filter to your family’s needs.

Meet the Fortitude Lineup

The Aquasure Fortitude series isn’t one-size-fits-all. It’s a well-engineered suite of filters built to target specific problems including sediment, chemicals, and heavy metals. Some tackle multiple contaminant types, while some work best as pre-filters to remove sediment and larger particles.

These filters aren’t just about cleaning water, they’re about making life easier. With straightforward designs and easy maintenance, the Fortitude lineup fits seamlessly into your home without hassle.

Fortitude Pro Series: The All-Star System

Need bigger protection for bigger demands? The Fortitude Pro Series gives you whole house protection for water that’s cleaner, healthier, and ready for whatever you need.

Designed to handle a wide range of common tap water contaminants, it combines high-performance media with a user-friendly, low-maintenance design.

Key Features:

• Media: Granular Activated Carbon (GAC) and KDF, with optional KDF85 upgrade for extra iron and hydrogen sulfide removal
• Contaminants removed: Chlorine, chloramine, heavy metals (lead, mercury), VOCs, pesticides, herbicides, industrial pollutants, rust, and scale
• Sediment Pre-Filter to remove larger particles
• Benefits: Low maintenance, supports high water flow, protects plumbing and appliances from buildup and corrosion
  

Bonus: The Fortitude Compact Under-Sink Filter

The Fortitude Pro is Aquasure’s powerhouse solution for whole home filtration. But the Fortitude Compact distills powerful filtration capacity into an under-sink system.

Contaminants Targeted

• Chlorine
• Organic compounds
• VOCs
• Taste and odor issues
• Heavy metals
• Microbial growth (KDF media)
• Scale and corrosion (Siliphos media model)

This system is perfect for homeowners who want strong filtration without a whole-house system. They’re also the perfect solution for apartments. Easy to install and maintain, they deliver clean water right where you need it most.

Fortitude V Series: Pre-Filters and Dual-Purpose Filters for Targeted Protection

The Fortitude V Series is built to give you solid pre-filtration and dual-purpose options that tackle sediment and chlorine-related contaminants. These filters make excellent pre-filters for other whole house systems like the Fortitude Pro and Harmony Series softener, protecting your main equipment from clogging and wear.

Note: Fortitude V2 replacement filters do not fit in Fortitude V housings.

High Flow Whole House 5 Micron Carbon Block Water Filter

Carbon filters are designed to trap tiny particles and chemicals that standard filters might miss. A 5-micron rating means they can catch contaminants as small as 5 micrometers, helping to clear out impurities that affect your water’s taste and safety.

The Fortitude V Carbon Block Water Filter works diligently to reduce chemical contaminants that impact not only the safety of your water but also its taste and odor.

What This Carbon-Block Filter Does:

• Targets chlorine, organic compounds, and volatile organic compounds (VOCs)
• Reduces chemical contaminants that affect water safety and quality
• Improves the taste and smell of your water by removing unpleasant odors
• Protects your plumbing and appliances from the corrosive effects of chlorine and other harsh chemicals

By removing these unpleasant elements, the filter delivers fresher, cleaner water throughout your home. This filter comes in a 10” size and 20” size.

Whole House 30 Micron Pleated Sediment Filter

Designed primarily to capture larger particles, these sediment filters extend the life of downstream filtration systems by removing coarse debris.

The Fortitude V Pleated Sediment Filter is washable, with a reusable design for longer life and lower maintenance. It’s an excellent pre-filter choice to protect your entire home’s water system. It’s available in a 10” and 20” size.

What This Pleated Sediment Filter Captures:

• Sediment 
• Sand
• Silt
• Clay
• Rust
• Dirt

Because these filters focus on larger particles, they don’t catch dissolved chemicals or microscopic contaminants. But they’re essential for protecting more sensitive filters and plumbing further down the line.

Whole House Sediment and Carbon Dual Purpose Water Filter

This Whole House Sediment and Carbon Dual Purpose Water Filter combines sediment and carbon media into a single filter cartridge available in a 10” & 20” size. This integration offers a simple, effective filtration solution perfect for homes with moderate contaminant loads, tackling both large particles and chemical impurities in one step.

Combined Filtration:

• Removes sediment, sand, rust, and other particles
• Reduces chlorine, organic compounds, VOCs, and unpleasant tastes and odors
• Good for smaller homes or as part of a multi-filter system

2-Stage Sediment + Carbon Block Filters

Two-stage systems use separate filters, one for sediment, one for carbon, to tackle different contaminants with precision. This 2-stage sediment & carbon filter setup is ideal for homes with moderate to high contaminant levels that need a little extra attention to detail, available in a 10” and 20” size.

Side by Side Filtration:

• The first stage uses a sediment filter to capture dirt, rust, and large particles that could clog or damage downstream equipment.
• The second stage employs a carbon block filter to reduce chlorine, organic compounds, VOCs, and improve taste and odor.

This smart setup lets you keep a close eye on each filter’s condition, making it simple to know exactly when it’s time for a replacement. That way, your water filtration stays consistent and effective without any guesswork.

Fortitude V2 Series: Upgraded Pre-Filters and Multi-Media Specialty Filters

The Fortitude V2 Series is the next step up from the V Series with enhanced media options and modular designs. These filters focus on sediment removal plus added benefits from siliphos or copper-zinc media to tackle scale and corrosion, making them ideal as standalone filters or in combination with other Aquasure systems.

Reminder: Fortitude V2 replacement filters only work with Fortitude V2 housings.

Whole House 30 Micron Pleated Sediment Filters

This pleated sediment filter is built for durability and reusability, making it a smart first line of defense. The upgraded V2 housing/filter comes in a standard and large size.

Durable, Washable Protection:

• Pleated surface maximizes filtration area for longer-lasting performance
• Washable and reusable, reducing replacement frequency and cost
• Captures sediment, rust, and large particles before they reach downstream filters

These filters are ideal for households dealing with visible particles or sediment-heavy water. By catching the big stuff early, they lighten the load on finer filters and keep your plumbing flowing freely.

Whole House Triple Purpose Filtration System

The Whole House Triple Purpose Filtration System filter combines sediment, carbon, and copper-zinc (SCZ) media to tackle multiple common water issues. This filter excels at removing sediment while targeting chemical contaminants and inhibiting microbial growth, making it an excellent choice for pre-filtration or standalone use.

Contaminants Targeted

• Sediment: sand, silt, rust, dirt, and other particles
• Chlorine and chemical contaminants affecting taste and odor
• Heavy metals and microbial growth through copper
• Organic compounds and VOCs (volatile organic compounds)

With its multi-media approach, the SCZ filter offers broad-spectrum protection for your home’s water supply. It’s a reliable option to help protect your plumbing and improve overall water quality, available in a standard and large size.

Multi-purpose Whole House Water Treatment System with Siliphos

This multi-purpose filter integrates sediment, carbon, and siliphos media for comprehensive filtration with an added focus on scale and corrosion prevention. It’s designed to remove particles and chemical contaminants while reducing scale buildup, making it ideal for homes dealing with hard water issues, available in a standard and large size.

Contaminants Targeted

• Sediment: dirt, rust, sand, and other particles
• Chlorine, chemicals, and VOCs affecting taste and safety
• Scale formation and corrosion through siliphos anti-scaling media
• Heavy metals and other impurities impacting plumbing and appliances

By combining filtration and scale prevention, this filter helps extend the life of your home’s water system while ensuring cleaner, better-tasting water throughout. It’s a smart choice for whole house filtration in areas prone to hard water.

How to Choose the Right Fortitude Filter for Your Home

If you’ve gotten this far down and still wondering which system to invest in, start by asking yourself the following questions:

1. What's in your water?

Before picking a filter, it helps to know what you’re dealing with. Get a water test or check your city’s annual water quality report. High chlorine calls for a carbon-based filter to improve taste and odor. If sediment or rust is visible, a whole house sediment water filter is your first line of defense to keep pipes and appliances safe.

2. How many people live in your home?

Water use scales up with your household size. More people means more water running through your system every day. Make sure you choose a filter with a high enough flow rate so no one has to wait for hot water or deal with reduced pressure during busy mornings.

3. Are you planning to expand or customize later?

The Aquasure Fortitude Pro is designed to be flexible, so you can add filters or upgrades as your water needs change. It lets you build the system that fits your home now and grow it over time without expensive replacements. It’s like starting with a solid toolkit and adding the right tools when you need them.

Answering those key questions helps narrow down your choices, but seeing the details side by side makes it easier to decide. The chart below lays out exactly what each Fortitude filter handles so you can pick the system that matches your water issues, household size, and future plans. It’s your quick reference to make sure you get the right fit from the start.
