Systematic Home Water Treatment

A Complete Home Water Solution
from Prefilter to RO / UF

Follow the correct sequence of prefilter, whole house water filter, whole house water softener, and final RO or ultrafiltration to manage the full household water journey.

  • Prefilter
  • Whole House Water Filter
  • Whole House Water Softener
  • RO / Ultrafiltration

Solution Logic

One incoming water line, four coordinated treatment stages

Each stage solves a different problem, while also protecting the next device downstream. That is what turns separate products into one systematic household solution.

The order matters: protect first, purify second, soften third, and then finish with a dedicated drinking-water stage.

01

Stage 1: Entry protection

Block sediment, rust, sand, and visible particles before they enter the core system.

02

Stage 2: Whole-house purification

Improve water quality across bathrooms, laundry, and service water with central filtration.

03

Stage 3: Scale control

Reduce hardness and limescale so heaters, pipes, valves, and appliances stay cleaner longer.

04

Stage 4: Drinking-water polishing

Use RO or UF at the point of use for direct drinking, cooking, and flavor-sensitive water.

Filtration Flow

How the purification path moves through the home

Water enters at the main inlet, passes through whole-house treatment, and then branches to the final point-of-use purifier for drinking water.

01

Prefilter

Intercepts sediment and visible particles before the rest of the system.

02

Whole House Water Filter

Improves whole-house water comfort before hardness treatment.

03

Whole House Water Softener

Reduces hardness and scale across the whole-house service line.

04

RO / UF

Finishes the drinking-water branch at the point of use.

  1. 01

    Transparent Prefilter

    Entry protection

    This is the first defensive layer of the system. It catches larger visible impurities before they reach the whole house water filter, softener, and terminal purifier.

  2. 02

    Whole House Water Filter

    Whole-house purification

    The whole house water filter improves general household water quality by reducing chlorine, odor, organics, and other impurities that affect every tap in the home.

  3. 03

    Whole House Water Softener

    Scale control

    The softener reduces hardness minerals such as calcium and magnesium, helping prevent limescale while improving comfort in showers, laundry, and hot-water equipment.

  4. 04

    RO or Ultrafiltration Drinking-Water Purifier

    Final point-of-use purification

    The last stage is dedicated to direct drinking and cooking water. Choose RO or UF according to local raw-water quality and the purification level you need.

Stage Details

What each stage is responsible for

The system works well when each device has a clear role in the filtration chain and is installed in the correct order.

01

Transparent Prefilter

Entry protection

Recommended location

At the main inlet of the house

This is the first defensive layer of the system. It catches larger visible impurities before they reach the whole house water filter, softener, and terminal purifier.

Main filtration targets

  • Sediment
  • Sand
  • Rust flakes
  • Suspended particles

What this stage helps achieve

  • Protects whole house water filter media and softener resin
  • Reduces fouling in valves, faucets, and appliances
  • Makes downstream maintenance more predictable

02

Whole House Water Filter

Whole-house purification

Recommended location

After the prefilter, before the softener

The whole house water filter improves general household water quality by reducing chlorine, odor, organics, and other impurities that affect every tap in the home.

Main filtration targets

  • Residual chlorine
  • Odor
  • Organic impurities
  • Unpleasant service-water taste

What this stage helps achieve

  • Cleaner water for bathing, laundry, and daily use
  • Helps stabilize water quality before softening
  • Improves comfort throughout the whole house

03

Whole House Water Softener

Scale control

Recommended location

After central filtration on the whole-house line

The softener reduces hardness minerals such as calcium and magnesium, helping prevent limescale while improving comfort in showers, laundry, and hot-water equipment.

Main filtration targets

  • Calcium
  • Magnesium
  • Hard-water scale

What this stage helps achieve

  • Protects heaters, boilers, and household appliances
  • Creates softer water for showering and laundry
  • Reduces spotting and buildup on fixtures

04

RO or Ultrafiltration Drinking-Water Purifier

Final point-of-use purification

Recommended location

At the kitchen or other direct-drinking water point

The last stage is dedicated to direct drinking and cooking water. Choose RO or UF according to local raw-water quality and the purification level you need.

Main filtration targets

  • Fine contaminants
  • Taste and odor issues
  • Micro-impurities
  • Dissolved solids when RO is selected

What this stage helps achieve

  • Creates a dedicated drinking-water line separate from service water
  • Lets purity level match your local water conditions
  • Improves confidence and taste at the final tap

RO or UF

Choose the final drinking-water stage based on local water quality

Both systems belong at the end of the process. The right choice depends on TDS, source-water stability, and the final purity level you want at the tap.

Selection notes

  • RO is the better fit when TDS is higher, water quality fluctuates more, or you want stronger purification capability.
  • Ultrafiltration is a better fit for stable municipal water and households that want mineral retention and lighter daily maintenance.
  • Final selection should consider source water, hardness, TDS, and the expected installation scenario.

Non-Electric RO Water Purifier

A stronger point-of-use purification option for users who want higher reduction of dissolved solids and stricter drinking-water treatment.

More suitable for

More suitable for higher TDS water, more complex raw-water conditions, and households that want a cleaner final drinking-water finish.

  • Suitable for direct drinking and cooking water
  • Designed for higher-purity end use
  • A strong option when source-water conditions are less stable

Non-Electric Ultrafiltration Water Purifier

A compact terminal purifier for stable water conditions where mineral retention and daily convenience matter.

More suitable for

More suitable for lower TDS municipal water, mineral retention, and users who prefer lighter use and maintenance.

  • Retains the minerals in the water
  • Good for drinking, cooking, and everyday kitchen use
  • Simple terminal purification when RO is not necessary
