Pre-filter Water Purifier: ChengrongTimes Redefines Whole-House Pre-Filtration
ChengrongTimes Pre-filter Water Purifier — Redefining the Pre-filter for Whole-House Water Filtration
What makes a good Pre-filter water purifier?
A traditional pre-filter water purifier usually focuses on removing visible particles such as sand, rust, and sediment. However, many users have found that after a period of use, the filter element becomes clogged. Even after repeated washing, the water flow may gradually decrease.
One of our loyal customers, who has many years of experience using ultrafiltration water purifiers, shared a practical solution with us. He found that when the ultrafiltration membrane was continuously exposed to reverse-flow water while being gently rubbed by hand, the cleaning effect was significantly improved. After reinstalling the membrane, the water flow was much higher than before cleaning.
Based on this valuable customer feedback, the ChengrongTimes ultrafiltration R&D team immediately began developing a new product: the ChengrongTimes Pre-filter Water Purifier.
The product has also been granted a utility model patent.
Unlike conventional pre-filters, the ChengrongTimes Pre-filter water purifier is designed around three key requirements: high filtration precision, high water flow, and convenient membrane cleaning.
It is designed to redefine what a whole-house Pre-filter water purifier can do.
1. High Filtration Precision: Keeping Contaminants Out of Your Whole House
As a Pre-filter water purifier, the unit is normally installed at the very beginning of a home’s main water inlet.
Its primary responsibility is to act as the first line of defense for the entire household water system. The goal is to intercept as many unwanted contaminants as possible before water enters the home’s pipes, appliances, and other water treatment equipment.
Most conventional pre-filters on the market use PP cotton, stainless steel mesh, or laminated discs as filter media. Their filtration precision is generally around 40–100 microns, which mainly allows them to remove relatively large visible particles such as sediment and rust.
The ChengrongTimes Pre-filter water purifier uses a specially developed ChengrongTimes pre-filtration ultrafiltration membrane with a filtration precision of 0.1 micron.
This 0.1-micron filtration precision is designed to target fine contaminants that ordinary pre-filters may not effectively intercept, including colloids such as humic substances and colloidal iron rust, algae, and spores.
For customers looking for a high-precision Pre-filter water purifier, the ChengrongTimes solution provides a fundamentally different approach to whole-house pre-filtration.
Why Does a Conventional Pre-filter Become Dirty?
A common misunderstanding is that a dirty filter element automatically means the filter has effectively removed all types of contaminants.
In reality, many conventional pre-filters primarily target larger visible particles. After extended use, fine contaminants that are not effectively intercepted may gradually accumulate on the filter surface.
A simple analogy is a handful of muddy water flowing through your fingers. After the muddy water drains away, your hands may become dirty. But that does not mean your fingers have become an effective filter for muddy water.
The same principle applies to a conventional Pre-filter water purifier.
A filter element becoming visibly dirty does not necessarily mean that it has effectively filtered all contaminants in the water.
The ChengrongTimes Pre-filter water purifier takes a different approach by using a 0.1-micron ChengrongTimes pre-filtration ultrafiltration membrane to provide finer filtration at the whole-house water inlet.
Real-World Application
One of our car-wash customers specifically selected a water circulation filtration system designed around the ChengrongTimes pre-filtration ultrafiltration membrane.
The customer was highly satisfied with the filtration results and even took photos to share the application with us.
Of course, ordinary household water generally does not reach the same contamination level as water used in a car-wash environment. However, this application demonstrates the potential of the ChengrongTimes membrane technology in demanding water filtration systems.
For customers considering a Pre-filter water purifier, real-world application experience is an important factor when evaluating filtration technology.
2. High Water Flow: Designed for Whole-House Water Demand
A Pre-filter water purifier is installed at the very beginning of the whole-house water supply system.
This creates a critical requirement: the filtration system must provide sufficient water flow without negatively affecting normal household water use.
If filtration precision is increased without considering water flow, the pressure and flow rate entering the home may be affected.
For this reason, the ChengrongTimes R&D team did not simply choose a 0.01-micron ultrafiltration membrane.
Instead, ChengrongTimes selected a 0.1-micron pre-filtration ultrafiltration membrane specifically designed around the requirements of whole-house pre-filtration.
This design balances filtration precision and water flow, making the ChengrongTimes Pre-filter water purifier suitable for whole-house applications where both filtration and water availability are important.
Because household water consumption varies from customer to customer, ChengrongTimes has also developed multiple models with different water-flow capacities.
This allows customers to select a suitable Pre-filter water purifier based on their household water requirements while helping ensure that normal household water use is not unnecessarily affected.
3. Easy Installation and Cleaning: Simple Hand Washing Without Removing the Filter
Cleaning convenience is another major difference between the ChengrongTimes Pre-filter water purifier and some conventional pre-filter designs.
Some existing designs require users to pull the entire filter element out of a stainless-steel housing before taking it somewhere else for cleaning.
This can create several practical problems.
Common Problems With Removing the Filter for Cleaning
1. Long filter elements can be difficult to remove
If the filter element is relatively long, pulling it completely out of the housing can be inconvenient.
2. Wet filter elements can easily create a mess
After filtration, the filter element is usually wet. Removing and carrying it elsewhere for cleaning can easily cause water to splash onto the user or surrounding area.
3. The filter element can be damaged during removal
During the process of pulling the filter element out for cleaning, accidental contact with other objects may scratch or damage the membrane.
4. Traditional hand washing may not provide sufficient cleaning
As our customer discovered, simply removing the membrane and rubbing it by hand may not provide the same cleaning effect as cleaning while water is continuously flowing in the reverse direction.
These practical problems inspired the ChengrongTimes R&D team to continuously improve the structure of the Pre-filter water purifier.
4. ChengrongTimes Pre-filter Water Purifier: Reverse Flushing + Hand Cleaning
After continuous structural innovation, ChengrongTimes developed a Pre-filter water purifier designed to make membrane cleaning easier and more effective.
The main advantages include:
1. No Need to Remove the Pipeline
The filter can be cleaned without removing the entire water pipeline.
2. No Need to Remove the Filter Element
Users do not need to completely remove the membrane from the system for routine cleaning.
3. Easy Housing Removal
The lower screw structure supports the housing and makes disassembly and installation easier.
The lower housing can be removed without directly damaging the filter element.
4. Reverse Flushing + Manual Rubbing
The ChengrongTimes Pre-filter water purifier combines reverse flushing with manual membrane rubbing.
This cleaning method is designed to improve cleaning effectiveness compared with simply removing the filter element and washing it separately.
5. Better Cleaning Efficiency and Longer Filter Life
More effective cleaning helps maintain the condition of the filter element and can contribute to a longer service life.
For a whole-house Pre-filter water purifier, easy maintenance is not just about convenience. It can also influence the long-term user experience and maintenance cost.
5. Why ChengrongTimes Pre-filter Water Purifier Is Different
A conventional Pre-filter water purifier may focus mainly on intercepting large visible particles.
ChengrongTimes takes a different approach by focusing on three core requirements:
0.1-micron filtration + high water flow + convenient cleaning.
These three factors are integrated into the design of the ChengrongTimes Pre-filter water purifier.
