What Harmful Substances Does Our Water Filtration System Eliminate From Your Home?

Written by Craig "The Water Guy" Phillips

Our multi-stage water filtration system tackles the contaminants most likely lurking in your tap water. We remove heavy metals like lead and arsenic, PFAS chemicals, pesticides, chlorine byproducts, and harmful bacteria, cysts, and parasites. Each stage targets a specific threat, so you're not relying on a single filter to do everything. There are a few limitations worth knowing about, too — and we'll walk you through everything below.

Key Takeaways

• Activated carbon stages remove chlorine, trihalomethanes, VOCs, and select pesticides, restoring clean taste and odor to your drinking water.
• Reverse osmosis membranes reduce dissolved heavy metals like lead and arsenic by up to 99% through a semipermeable barrier.
• Certified RO and carbon combinations achieve up to 98–100% reduction of dangerous PFAS compounds, including PFOA and PFOS.
• Ultrafiltration membranes block biological threats like Giardia, Cryptosporidium, and most bacterial pathogens before water reaches your tap.
• Sediment pre-filters capture sand, silt, and particulate matter, protecting downstream stages and extending overall system performance.

What Does Our Water Filtration System Remove?

Our water filtration system tackles a wide range of harmful substances through multiple treatment stages, each designed to target specific contaminants.

We've engineered each layer with purpose. Activated carbon eliminates chlorine, VOCs, select pesticides, and certain PFAS compounds — restoring your water's taste and odor. Our reverse-osmosis membrane then reduces dissolved salts and heavy metals like lead, arsenic, and fluoride by 90% or more. Ultrafiltration and nanofiltration components block parasites like Giardia and Cryptosporidium, most bacteria, and even some viruses. Sediment pre-filters protect everything downstream by capturing sand, silt, and particulate matter.

We'll be honest, though — no household system eliminates every contaminant. That's why we recommend identifying your water's specific threats and choosing certified treatments matched precisely to them.

Lead, Arsenic, & Heavy Metals Our System Filters Out

Heavy metals like lead and arsenic don't belong in your drinking water — and our reverse osmosis membrane removes up to 99% of them by forcing water through a semipermeable barrier that blocks dissolved ions and small particles.

Sediment pre-filters protect that membrane while capturing sand and silt, preserving removal performance over time.

Our granular and catalytic carbon stages adsorb metal-organic complexes and strip chlorine that would otherwise interfere with the process.

For lead specifically, our NSF/ANSI 53- and 58-certified components reduce concentrations below regulatory action levels — provided you follow our maintenance schedule.

High iron or manganese in your feed water shortens filter life, so we recommend pre-treatment or more frequent cartridge changes to keep heavy-metal removal rates where they need to be.

PFAS, Pesticides, & Chlorine Byproducts We Remove

From invisible agricultural runoff to the disinfection chemicals your utility adds at the plant, our system's activated carbon and reverse osmosis stages work together to strip out the contaminants that standard filters miss.

Activated carbon eliminates chlorine, trihalomethanes, and other disinfection byproducts affecting taste, odor, and long-term health. Our catalytic carbon media goes further, breaking down chloramines that conventional GAC can't touch.

For pesticides and VOCs, specialized carbon and anion exchange combinations handle what agricultural runoff delivers to your tap.

On PFAS—PFOA, PFOS, and their cousins—our certified RO and carbon combination achieves up to 98–100% reduction in lab testing. That said, removal efficiency varies by compound and concentration, so we recommend testing your water and verifying NSF-certified reduction claims for your specific contaminants.

Bacteria, Cysts, & Waterborne Parasites We Target

Chemical contaminants aren't the only threat hiding in your water—biological ones can be just as dangerous, and in some cases, faster-acting.

Parasites like Giardia and Cryptosporidium, along with bacteria like E. coli and Salmonella, don't announce themselves.

Our microfiltration and ultrafiltration membranes operate at pore sizes between 0.001 and 5 microns—small enough to intercept cysts, protozoa, and most bacterial pathogens before they reach your glass.

For households on private wells or with immunocompromised members, we've guaranteed our systems meet NSF/ANSI 53 certification standards for cyst and bacteria reduction.

We also build in strict cartridge-change protocols, because a neglected filter becomes a breeding ground.

Biological threats demand a system that's both precise and consistently maintained—and that's exactly what we've built.

What Our Water Filtration System Cannot Remove

Even the most advanced filtration system has its limits, and we believe you deserve to know exactly where ours are. Transparency builds trust—and trust starts with honesty.

Here's what our system doesn't fully eliminate:

• Dissolved inorganic ions like nitrate and fluoride resist standard carbon filtration
• Certain VOCs can bypass reverse osmosis without dedicated carbon pre/post-treatment
• Beneficial minerals like calcium and magnesium are stripped during RO and distillation
• PFAS removal varies—some filters capture 100%, others only 22–66% depending on the model

No single system wins every battle. That's why understanding your specific water profile matters.

We recommend pairing our system with periodic water testing so you're always making informed, confident decisions about your household's water.

Frequently Asked Questions

What Contaminants Does a Whole Home Water Filtration System Remove?

Our whole-home system removes sediment, chlorine, chloramines, VOCs, pesticides, iron, manganese, and hydrogen sulfide. We're targeting the contaminants that damage your plumbing, compromise your health, and steal the clean, great-tasting water your family deserves.

Can Water Filters Cause Health Issues?

Yes, they can—if we neglect maintenance or choose the wrong technology. Skipping filter replacements breeds bacteria, while removing chlorine without proper safeguards invites microbial growth in your plumbing, turning protection into risk.

Do Water Filters Get Rid of Forever Chemicals?

Yes, some of our filters effectively eliminate PFAS "forever chemicals"—certain pitcher, countertop, and reverse osmosis systems reduce them by nearly 100%, though performance varies markedly by brand, model, and the specific PFAS compounds present in your water.

What Can Water Filters Not Remove?

We can't remove everything—dissolved salts, nitrates, fluoride, and viruses often slip through standard filters. That's why we pair reverse osmosis and specialized media together for thorough, verified protection.
