Overview

What's actually in your tap water and what to filter for

Many people buy bottled water instead of using the tap — but continually buying bottled water gets expensive. There is a better way.

Installing a water filtration system brings you the same great taste as bottled water while saving you money. Over a year or two, a home water filtration system is significantly cheaper than continuing to buy bottled water — and it delivers clean, crisp water from every tap in your home.

Why homeowners across North Louisiana choose filtered water

  • Whole-house filtration for cleaner water at every tap
  • Better-tasting water without the cost of bottled water
  • Water softener installation to fight hard-water buildup
  • Professional sizing and installation for your home

Three levels of filtration to consider

  1. Whole-home filtration — filter at the point where water enters the house; every tap gets filtered water. Best for chlorine, sediment, and general taste improvement. Quoted by system size after a water test
  2. Under-sink RO (reverse osmosis) — 4 or 5-stage system under the kitchen sink with a dedicated drinking tap. Removes 95–99% of TDS, heavy metals, nitrate, pharmaceuticals, and PFAS. The best drinking water you can have at home
  3. Refrigerator or carafe filtration — basic chlorine and taste reduction for drinking water only — the cheapest option, but it doesn't filter the rest of the house

We often recommend a combination for North Louisiana homes — whole-home filtration to remove chlorine at every tap, plus an RO under the kitchen sink for drinking and cooking water. Both are quoted as one job, protecting appliances from chlorine corrosion and giving you restaurant-quality drinking water.

What whole-home filtration actually removes

Depends on the system. A standard activated-carbon whole-home filter removes chlorine (>95%), taste and odor issues, and light sediment. A catalytic carbon system adds chloramine removal. Multi-stage systems can add sediment pre-filters, heavy metal removal (KDF media), and bacterial protection (UV stage). Does not remove hardness — that's a softener's job. Does not remove TDS significantly — that's RO's job.

Classic Membership members get

Annual filter replacement coordination and priority scheduling. For a family actively buying bottled water, an RO system pays for itself in 1–2 years.

Warning signs

Reasons to Consider Water Filtration

Water filtration is a quality-of-life upgrade. Here's when it makes sense.

  • You can smell or taste chlorine in tap water or the shower

  • You buy bottled water regularly because the tap tastes bad

  • Sediment or rusty particles occasionally come out of the tap

  • White spots on dishes, shower glass, and bathroom faucets (TDS)

  • Skin or hair feels dry and irritated after showers

  • Concerned about pharmaceuticals, PFAS, or other trace contaminants

  • Home on well water with taste or bacteria issues

  • Water heater, dishwasher, or washing machine failing prematurely

  • Coffee or tea tastes off even with a good machine

  • Concerned about lead in an older home with original copper solder joints

The Process

How a Water Filtration Install Runs

Mark Johnson & Sons Plumbing technician testing water quality before installing a filtration system

On the truck

Professional tools, parts, and diagnostics — every call.

  1. Water test and recommendation

    Tech tests TDS, chlorine, hardness, pH, and iron levels at the kitchen tap. Based on the results and what you're trying to achieve, we recommend the right system — whole-home, RO, or both.

  2. Quote options

    Usually 2–3 options at different price points. Entry-level carbon filter for chlorine only, mid-range multi-stage for chlorine + sediment + heavy metals, premium system with catalytic carbon + UV. Plus RO options for drinking water.

  3. Install day

    Whole-home filter installs at the main water entry inside the house or garage. Plumbed with bypass valves so filters can be changed without shutting off the house water. Half-day install for whole-home only, full day if adding RO under the sink.

  4. Commission and test

    Flush the filter media, verify flow rate, pressure, and taste. Re-test TDS and chlorine to confirm the system is performing as spec.

  5. Annual filter service

    Filters need replacement on a schedule — every 6–12 months for standard carbon, every 12 months for catalytic, every 12–24 months for RO membranes. Classic Membership coordinates this automatically so you don't forget.
