Water Filtration in Shreveport, LA

Whole-House and Point-of-Use Filtration Systems Installed by Licensed Plumbers

The water flowing through your Shreveport home can carry chlorine, sediment, dissolved minerals, and trace contaminants that affect how it tastes, smells, and interacts with your plumbing. Mark Johnson & Sons Plumbing installs professional water filtration systems that target the specific issues present in your water supply, delivering cleaner and better-tasting water from every tap in your house. As part of our comprehensive water treatment services in Shreveport, we deliver professional results backed by decades of experience.

Why Water Filtration Matters in Shreveport

Shreveport’s drinking water originates primarily from Cross Lake and undergoes treatment at the municipal water plant before entering the distribution system. Chlorine is added during treatment to kill bacteria and pathogens — an essential step for public health, but one that leaves a chemical taste and odor that many homeowners find unpleasant. By the time water reaches homes in areas like Ellerbe Road, Line Avenue, or the Southfield neighborhoods, chlorine levels are still measurable and noticeable.

Beyond chlorine, Shreveport’s water can contain sediment from aging distribution infrastructure, seasonal fluctuations in organic compounds from Cross Lake, and trace levels of contaminants that meet federal limits but concern health-conscious residents. The City publishes an annual Consumer Confidence Report detailing detected substances — reviewing this alongside a home water test gives you a complete picture of what your family is consuming.

A properly designed filtration system removes these unwanted elements before water reaches your glass, your shower, your ice maker, or your cooking pot. The result is noticeable immediately — water that tastes clean, doesn’t smell like a swimming pool, and doesn’t leave residue on surfaces or in appliances.

Our Water Filtration Services

Whole-House Carbon Filtration

A whole-house carbon filter installs on your main water line and treats every gallon entering your home. Activated carbon media adsorbs chlorine, chloramines, volatile organic compounds, and taste and odor-causing substances. This is the most popular residential filtration solution in Shreveport because it addresses the most common complaints — chemical taste and odor — at an affordable price point with minimal maintenance.

Whole-House Multi-Stage Filtration

For homes with more complex water quality issues, multi-stage systems combine sediment filters, carbon media, and specialty media in a single integrated unit. Each stage targets different contaminants — sediment prefiltration protects downstream media, carbon handles chemicals and organics, and specialty media addresses iron, manganese, or hydrogen sulfide if testing reveals their presence.

Under-Sink Reverse Osmosis

Reverse osmosis systems push water through a semipermeable membrane that removes up to 99 percent of dissolved contaminants including lead, fluoride, arsenic, nitrates, pharmaceuticals, and total dissolved solids. We install compact RO systems under kitchen sinks with a dedicated dispensing faucet and pressurized storage tank. This delivers the highest level of purification for drinking and cooking water.

Refrigerator and Ice Maker Filtration

Many homeowners filter their kitchen tap water but forget that their refrigerator dispenser and ice maker connect to an unfiltered supply line. We install inline filtration on the water line feeding your refrigerator so that every glass of water and every ice cube benefits from the same filtration as your kitchen sink.

Sediment Filtration

Homes near older water mains or those that notice particles, cloudiness, or grit in their water benefit from dedicated sediment filtration. These systems capture sand, rust, silt, and pipe debris using pleated or spun cartridges rated down to 5 microns or finer. Sediment filters also protect downstream equipment like water softeners and water heaters from particle damage.

UV Disinfection

For Shreveport homeowners who want an additional layer of biological protection — particularly those on well water supplementing city supply or with immunocompromised family members — ultraviolet disinfection neutralizes bacteria, viruses, and protozoa without adding any chemicals to your water. A UV unit installs inline after your filtration system and treats water with germicidal UV-C light as it passes through.

Frequently Asked Questions

What contaminants does water filtration remove?

It depends on the system. Carbon filters remove chlorine, chloramines, VOCs, and taste/odor compounds. Reverse osmosis removes dissolved solids including lead, fluoride, arsenic, nitrates, and pharmaceuticals. Sediment filters capture particles. We select and combine technologies based on your water test results to address everything present in your specific supply.

How much does a whole-house water filtration system cost?

A whole-house carbon filtration system typically runs $1,200 to $2,800 installed in a Shreveport home. Multi-stage systems with specialty media cost more depending on the complexity. Under-sink reverse osmosis systems are usually $400 to $900 installed. We provide a detailed quote after testing your water and assessing your plumbing.

Will a whole-house filter reduce my water pressure?

A properly sized system has a negligible impact on water pressure. We calculate your home’s peak demand and select a filter housing and media bed that handles the required flow rate without restriction. Filter cartridges that are overdue for replacement can reduce flow, which is why we recommend a regular maintenance schedule.

How often do water filters need to be changed?

Carbon filter media in whole-house systems typically lasts 6 to 12 months depending on water usage and the level of contaminants being removed. Sediment pre-filters should be checked quarterly. Reverse osmosis membranes last 2 to 3 years, while their carbon pre and post-filters need replacement every 6 to 12 months. We provide a maintenance schedule specific to your system.

Is a whole-house filter or an under-sink filter better?

They serve different purposes. A whole-house filter treats all water in your home — showers, laundry, and every faucet — addressing chlorine and sediment everywhere. An under-sink RO system provides the highest level of purification at a single point, ideal for drinking and cooking water. Many Shreveport homeowners install both for comprehensive coverage.

Do I really need water filtration if my city water is treated?

Municipal treatment ensures your water meets federal safety standards, which is focused on preventing disease. It doesn’t optimize for taste, odor, or trace contaminants that concern many families. Filtration bridges the gap between “meets minimum standards” and “the quality you actually want in your home.”

Can water filtration help with dry skin and hair?

Yes. Chlorine in shower water strips natural oils from skin and hair. A whole-house carbon filter that removes chlorine from your entire water supply can noticeably improve skin moisture and hair softness. Many Shreveport residents report this as one of the first benefits they notice after installation.

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

Filters remove contaminants, chemicals, and particles from water. Softeners remove hardness minerals — calcium and magnesium — that cause scale and soap performance issues. They solve different problems. Shreveport homes with both hard water and taste/odor concerns benefit from installing both a softener and a filter, which we can configure as an integrated system.

How long does installation take?

A whole-house filter typically installs in 2 to 3 hours. Under-sink reverse osmosis systems take 1 to 2 hours. Installations that require plumbing modifications — such as adding a loop for the main line filter — may take slightly longer. We’ll provide a time estimate with your quote.

Do you service filtration systems you didn’t install?

Yes. We maintain and repair water filtration systems from all major manufacturers regardless of who installed them. If your current system needs filter replacement, repair, or performance evaluation, we can help.
