Frequently Asked Questions about Water

Water Treatment & Filtration FAQ's

How do I know what water filter system I need?

The best starting point is a comprehensive water test. Common issues like iron staining, sulfur odor, hard water, high nitrates, or bacteria each require different solutions. Once we see your water results, we can recommend the most effective system.

Do water softeners remove iron and manganese?

Standard water softeners can help with mild iron, but they are not very effective against high levels of iron and manganese. For stubborn iron and manganese problems, we recommend specialized iron/manganese removal systems or a combination approach.

What are the most common problems with well water?

Well water frequently contains higher levels of iron, manganese, sulfur (rotten egg smell), hardness, tannins, nitrates, arsenic, bacteria, and silica. Unlike city water, private wells are not regulated, so regular testing and proper treatment are essential.

What is the difference between UV sterilization and oxidation disinfection?

UV sterilization uses ultraviolet light to destroy bacteria and viruses without adding chemicals. Oxidation disinfection (ozone, hydrogen peroxide, or advanced oxidation) is stronger against organics and can also oxidize iron, manganese, and sulfur. Many well water users combine both for maximum protection.

Will a whole house filter remove PFAS and “forever chemicals”?

Many of our advanced whole house and reverse osmosis systems are highly effective at reducing PFAS. For the best results, we often recommend multi-stage systems with specialized carbon and adsorption media.

How often should I replace my water filters?

It depends on your water usage and the type of filter. Most pre-filters and carbon blocks should be changed every 6–12 months. RO membranes typically last 2–3 years, while specialty media (iron, arsenic, etc.) can last 5–10 years with proper maintenance.

What is the difference between a water softener and a water conditioner?

A water softener removes hardness minerals (calcium and magnesium) through ion exchange. A water conditioner (salt-free) usually uses template-assisted crystallization or magnetic technology to prevent scale without removing the minerals.

Do your filters remove bacteria and viruses from well water?

Yes. For biological contaminants, we recommend UV sterilizers or oxidation disinfection systems. These are highly effective at destroying 99.99% of bacteria, viruses, and cysts without adding chemicals to the water.

What’s the difference between a whole house filter and an under-sink RO system?

A whole house filter treats all water entering your home (including showers and laundry). An under-sink RO system provides ultra-pure water specifically for drinking and cooking. Many customers use both together for complete protection.

Can your systems remove sulfur smell (rotten egg odor)?

Yes. We offer specialized sulfur removal systems using oxidation and catalytic media that effectively eliminate hydrogen sulfide and the rotten egg smell.

Do your shower head filters really remove chlorine?

Yes. Our shower head filters significantly reduce chlorine, chloramine, and heavy metals, which helps prevent dry skin, brittle hair, and that strong chemical smell during showers.

Do I need a water softener if I already have a whole house filter?

It depends on your water. A whole house filter removes contaminants, but only a water softener can effectively reduce hardness minerals that cause scale buildup, dry skin, and poor soap lathering.

How long do whole house water filter systems typically last?

With regular maintenance, high-quality whole house systems (especially Crystal Quest Big Blue and specialty units) can last 10–20 years. The filter media and cartridges need periodic replacement.

Do you offer systems for both well water and city water?

Yes. We carry solutions for both. City water usually needs chlorine, PFAS, and lead removal, while well water often requires treatment for iron, sulfur, bacteria, arsenic, and nitrates.

What is tannin and why does it stain my laundry and fixtures?

Tannins are natural organic compounds from decaying vegetation. They cause yellow or brown discoloration in water and can stain laundry, fixtures, and glassware. We offer specialized tannin removal systems using anion exchange resin.

Can high nitrates in water affect my baby’s health?

Yes. High nitrate levels can interfere with the blood’s ability to carry oxygen, especially in infants under 6 months (a condition called methemoglobinemia or “blue baby syndrome”). Nitrate removal systems are highly recommended in these cases.

Will installing a whole house system reduce my water pressure?

Quality whole house systems are designed to maintain good pressure. However, very high-flow-demand homes may need a larger system or multiple tanks. We can help size the right system for your household.

Are your systems NSF certified?

Yes. All of our primary filtration media and systems use NSF-certified components where applicable, giving you confidence in their performance and safety.

How do I maintain my UV sterilizer?

UV lamps should be replaced once per year, and the quartz sleeve should be cleaned every 6–12 months. We carry replacement lamps and sleeves for all popular UV systems.

Can I install a whole house water filter system myself?

Many of our simpler systems (like Big Blue carbon filters) can be installed by a handy homeowner. However, we strongly recommend professional installation for whole house reverse osmosis, water softeners, UV systems, and any system connected to high-pressure lines.

Problem Water – Specific FAQs

Why does my water leave red or orange stains on fixtures and laundry?

Red or orange staining is almost always caused by high levels of iron. Even small amounts can oxidize and leave stubborn stains. Our iron and manganese removal systems are specifically designed to eliminate this problem.

My water smells like rotten eggs. What causes this and how do I fix it?

The rotten egg smell is caused by hydrogen sulfide gas, commonly found in well water. We offer specialized sulfur removal systems using oxidation and catalytic media that effectively eliminate the odor.

Why is my water yellow or brown even after running it for a while?

Yellow or brown water is typically caused by tannins (natural organic matter from decaying plants). Tannins are difficult to remove with standard filters. We recommend our tannin-specific anion exchange systems.

My water test showed high arsenic levels. Is this dangerous?

Yes. Arsenic is a known carcinogen with no safe exposure level. Long-term consumption can increase the risk of cancer and other serious health issues. We offer dedicated arsenic removal systems using high-capacity media designed for this specific contaminant.

Can fluoride in my water be harmful?

Many people prefer to reduce fluoride even though it’s added to municipal water for dental health. We offer fluoride removal systems using activated alumina or bone char carbon that can reduce fluoride levels significantly.

Why does my water taste bitter or metallic?

A bitter or metallic taste is often caused by high levels of iron, manganese, copper, or sulfates. Our targeted metal and sulfate removal systems usually resolve this issue quickly.

My water leaves white scale on faucets and inside my coffee maker. What should I do?

This is classic hard water caused by high calcium and magnesium. A water softener is the most effective solution for removing hardness minerals and preventing scale buildup.

I’m concerned about bacteria in my well water. Should I use a UV system?

Yes. UV sterilization is one of the most effective and chemical-free ways to destroy bacteria, viruses, and cysts. It’s especially recommended for well water that tests positive for coliform or E. coli.

What is silica and why is it so difficult to remove?

Silica forms extremely hard, glass-like deposits that regular softeners can’t handle. It can damage appliances and etch glassware. We offer specialized silica removal systems designed specifically for this stubborn mineral.

Do I need different systems for iron, sulfur, and bacteria, or can one system handle everything?

It depends on your water test results. Some problems can be solved with a single multi-stage system, while others (like high iron + bacteria) work best with a combination of specialized filters and UV or oxidation.
