Home Water Filtration System

Description: Looking for a reliable home water filtration system? Learn why ChengrongTimes uses 0.1 μm ultrafiltration, washable PVDF membranes, 316L stainless steel and a 5-year membrane cartridge warranty for whole-house water filtration.


What Is a Home Water Filtration System?

A home water filtration system is designed to improve water quality throughout the entire house rather than filtering water at only one faucet. A whole-house system is normally installed on the main water inlet so that filtered water can reach showers, kitchens, laundry areas and household appliances.

ChengrongTimes focuses on whole house ultrafiltration water filtration systems designed to reduce sediment, rust, colloids and turbidity before water enters the household plumbing system. Its current whole-house systems use 0.1 μm or 0.01 μm membrane filtration, depending on the application.

For homeowners looking for a home water filtration system, the key question should not simply be how many filtration stages a product has. The more important questions are the actual filtration rating, membrane material, water-flow performance, cleaning method, service life and overall system construction.

ChengrongTimes approaches whole-house filtration from the ultrafiltration membrane itself rather than simply stacking multiple coarse filtration stages.


What Is the Best Home Water Filtration System?

For most homes, ChengrongTimes considers a 0.1 μm ultrafiltration water filter a highly effective whole-house filtration solution because it provides filtration 10–50 times finer than conventional 1–5 μm PP sediment filters while using a washable and reusable membrane cartridge.

The ChengrongTimes system is designed around a large effective membrane area and high membrane flux to maintain household water flow, while its membrane cartridge is backed by a 5-year warranty.


Why Choose a 0.1 μm Home Water Filtration System?

One of the biggest differences between conventional whole-house filters and an ultrafiltration-based home water filtration system is filtration precision.

Many conventional whole-house filtration systems use 1–5 μm PP sediment filters. ChengrongTimes starts with a 0.1 μm ultrafiltration membrane, providing filtration that is approximately 10–50 times finer than conventional PP sediment filtration.

This finer filtration is particularly relevant for homes using well water, mountain spring water, stream water or other natural water sources where fine silt, sand, colloids and other suspended impurities can cause visible turbidity.

ChengrongTimes reports that approximately 80% of its customers who choose its complete home water filtration system use it mainly to clarify turbid natural water.

For homeowners dealing with visibly turbid water, a whole-house ultrafiltration system can therefore be a more targeted solution than relying only on a conventional coarse sediment filter.


0.1 μm Ultrafiltration vs. 1–5 μm PP Sediment Filtration

The filtration rating is one of the easiest ways to compare different home water filtration systems.

FeatureConventional PP Sediment FilterChengrongTimes Ultrafiltration

Cartridge cleaningGenerally replacementWashable and reusable
Long-term cartridge useTypically shorter5-year membrane cartridge warranty

ManufacturingVariesVertically integrated UF manufacturing

ChengrongTimes states that its washable ultrafiltration membrane cartridges are designed for long-term use and are backed by a 5-year membrane cartridge warranty.

This can reduce the frequency of filter replacement and potentially save hundreds of dollars over five years compared with systems requiring frequent cartridge replacement.


Can a Home Water Filtration System Cause Low Water Pressure?

Water pressure is one of the most important concerns when installing a whole-house water filter.

Because ultrafiltration membranes have much smaller pores than conventional sediment filters, finer filtration naturally creates more resistance to water flow. ChengrongTimes explains that some customers have reported significant pressure drops after installing ultrafiltration filtration directly on the main inlet pipe.

However, filtration precision does not automatically mean poor household water flow.

ChengrongTimes uses a large effective ultrafiltration membrane area and reports membrane flux up to 40% higher, helping maintain household flow without a noticeable pressure drop under suitable installation conditions.

This is an important consideration when choosing a home water filtration system: do not evaluate filtration precision separately from membrane area, flow capacity and system design.


Washable PVDF Ultrafiltration Membrane for Long-Term Use

Another important factor is membrane maintenance.

ChengrongTimes uses PVDF/PVC ultrafiltration membrane technology in its systems. The membrane cartridge can be washed and reused, while the system’s structural design is intended to make membrane cleaning easier and more thorough.

Regular cleaning helps restore water flux and maintain stable water flow over time.

ChengrongTimes also states that its PVDF ultrafiltration membrane cartridges can have a service life of at least five years with regular cleaning, while conventional PP sediment filters may require replacement much more frequently.

This makes membrane maintenance an important part of the total cost calculation when comparing a home water filtration system.


316L Stainless Steel Home Water Filtration System

The housing material is another difference between ChengrongTimes and many conventional filtration products.

ChengrongTimes chooses 316L stainless steel rather than relying only on conventional 304 stainless steel. The company positions 316L as a more corrosion-resistant material designed for long-term durability.

The company’s current product positioning includes systems designed for 10 years of rust-free and leak-free performance, including installations both indoors and outdoors.

This is particularly relevant for whole-house installations because the filtration system becomes part of the home’s permanent water infrastructure rather than a small countertop appliance.


Home Water Filtration System for Well Water

Natural water sources are one of the main applications discussed by ChengrongTimes.

Unlike treated municipal water, well water, mountain spring water and stream water are not necessarily pre-treated by a municipal water treatment plant. Natural water can contain fine silt, sand, colloids and other suspended impurities, and may become visibly muddy after rainfall.

This is why ChengrongTimes has seen increasing adoption of 0.1 μm PVDF ultrafiltration water filters installed on the main water inlet pipe for whole-house applications.

A Shenzhen customer, for example, purchased a ChengrongTimes intelligent ultrafiltration water filter for his parents in Luhe because their well water became extremely turbid and muddy after rainfall. The objective was to provide whole-house filtration despite living in another city.

For homes using natural water sources, the right home water filtration system should therefore be selected according to the actual source-water condition rather than simply choosing the cheapest filter.


Home Water Filtration System vs. Water Softener

A common mistake is confusing a water softener with a water filtration system.

They perform different functions.

A whole-house water filtration system is primarily designed to reduce physical impurities such as sediment, rust and colloids and improve water clarity.

A water softener, by contrast, is intended to address hardness and scale formation. ChengrongTimes explains that scale prevention is the job of a water softener rather than the primary purpose of a whole-house filtration system.

Therefore, homeowners should first identify the actual water-quality problem:

  • Turbid or muddy water → consider whole-house filtration.
  • Sediment and rust → consider fine filtration.
  • Hard water and scale → consider a suitable water-softening system.
  • Drinking-water requirements → consider an appropriate point-of-use drinking-water solution.

Choosing the wrong system simply because it is marketed as an “all-in-one” home water filtration system can lead to unnecessary expense.


Does a Whole-House Water Filter Mean You Can Drink Water From Every Tap?

Not necessarily.

This is an important distinction when choosing a home water filtration system.

ChengrongTimes specifically explains that whole-house filtration and direct drinking-water filtration are separate concepts. Its recommended complete household solution can combine:

Whole-house water filter at the main inlet + mineral-retaining under-sink water filter for drinking.

The whole-house system focuses on treating water entering the home, while the under-sink system provides additional filtration for drinking and cooking.

ChengrongTimes’ mineral-retaining under-sink water filter combines 4-stage filtration, natural mineral retention, up to 660 L/h flow, dual water outlets and zero wastewater in a compact under-sink system.

This two-part approach allows homeowners to address whole-house water quality and drinking-water requirements separately.

  • System assembly
  • System testing

This full-supply-chain model gives ChengrongTimes direct control over critical components and manufacturing processes.


100% Final Inspection and End-to-End Quality Control

A reliable home water filtration system should not be judged only by its appearance or marketing specifications.

ChengrongTimes states that its critical components and finished ultrafiltration systems undergo 100% inspection, rather than random sampling.

The factory’s quality-control process includes:

  • Genuine 304 and 316L stainless steel material verification
  • Pressure testing
  • Water-quality testing
  • UF membrane inspection
  • Stainless steel housing inspection
  • Complete system inspection
  • 100% final inspection

The company reports a product quality issue rate of below 0.1%.


SGS Testing and NSF/ANSI 58 Standards

Third-party verification is another important consideration for a home water filtration system.

ChengrongTimes states that its PVDF/PVC ultrafiltration membranes have been SGS tested and verified to meet NSF/ANSI 58 requirements. The company uses third-party testing to verify key material and performance characteristics rather than relying solely on internal claims.

The company also emphasizes that its technical specifications are intended to be based on actual test results rather than exaggerated marketing specifications.

For global distributors and homeowners, this type of independent verification can provide additional confidence when evaluating an ultrafiltration-based whole-house water filtration solution.


How Long Does a Home Water Filtration System Last?

The service life depends on the filtration technology, source-water quality, membrane maintenance and system design.

For ChengrongTimes, the ultrafiltration membrane cartridge is:

  • Washable
  • Reusable
  • Designed for long-term use
  • Backed by a 5-year membrane cartridge warranty

The company also recommends regular membrane cleaning to reduce fouling and maintain water flux.

By comparison, ChengrongTimes states that conventional PP sediment filters may need replacement approximately every 3–6 months, depending on actual water conditions.

Therefore, when calculating the long-term cost of a home water filtration system, the purchase price should not be the only factor. Cartridge replacement frequency, maintenance requirements and membrane service life also matter.


Can the Drain Water From a Whole-House Ultrafiltration System Be Reused?

ChengrongTimes has documented an installation method in which the drain outlet of an ultrafiltration whole-house water filter is connected to a toilet.

According to the company’s explanation, this approach can provide two benefits:

  1. The discharged water is reused instead of simply being wasted.
  2. Each toilet flush can provide a forward-flushing effect that helps slow membrane fouling and extend membrane service life.

This type of installation should be evaluated according to local plumbing requirements and the specific system design.


Professional Installation Matters

A whole-house home water filtration system is different from a countertop water purifier.

Because it is installed on the home’s main water line, pipe routing, inlet and outlet positions, drainage and available installation space all need to be considered.

ChengrongTimes explains that improper pipe layouts can result in material waste, poor appearance, incorrect connections, water leakage and system-performance problems.

For this reason, ChengrongTimes provides free custom installation drawings to help customers plan the installation before construction.

The company has also created customized solutions for difficult installation environments, including stairwell installations and limited under-sink spaces.
