HDX4PF4 30‑Micron Pleated Sediment Whole‑House Water Filter Cartridge
Introduction:If you are sourcing HDX4PF4 pleated sediment filter cartridge for residential whole‑house water pretreatment, this drop‑in replacement element adopts pleated polypropylene media with 30‑micron rating for effective sediment interception. It delivers enlarged filtration surface, high dirt‑holding capacity and stable high‑flow performance, capturing sand, rust particles, silt and suspended solids from tap water. As primary pre‑treatment filter for household water systems, it protects downstream water appliances and extends service life of subsequent water‑treatment components. With standard 10‑inch large‑body dimension, it fits most standard whole‑house filter housings. As cost‑effective alternative supplied by Chinese filter manufacturer, it suits residential and light‑commercial water‑filtration projects across global markets.

Product Overview
HDX4PF4 is a widely‑used 10‑inch pleated sediment water filter cartridge, mainly designed for whole‑house residential water pretreatment and light‑commercial water‑filtration systems. It features 9‑7/8 inch nominal length, 4.5‑inch outer diameter, 1‑1/10‑inch inner diameter structure. The filter media is thermally bonded pleated polypropylene, with nominal 30 μm filtration rating, focusing on removing sediment, sand, rust, silt and large‑particle impurities from raw tap water. Central support tube is made of rigid polypropylene, end caps adopt stable plastic‑sol sealing structure without adhesive leakage risk. It can operate under standard household water‑system pressure, and complies with relevant material safety requirements for drinking‑water contact. This interchangeable sediment cartridge can be directly installed into most 10‑inch big‑blue filter housings without modification, commonly matched with whole‑house pre‑filter systems, ice‑maker inlet water protection and light‑duty industrial pre‑filtration scenarios.
Working Principle
HDX4PF4 pleated water filter cartridge adopts outside‑to‑inside liquid flow path. Untreated tap water flows into the cartridge from outer pleated surface. Large‑size sediment, rust particles and silt are trapped on outer pleated layers; medium‑sized particles are gradually intercepted inside multi‑layer pleated gaps by depth‑filtration effect. The pleated structure greatly expands effective filtration area, slows down blocking speed and improves dirt‑holding capacity. After filtration, clean water flows inward through polypropylene central core and flows out from inner core outlet. Reliable end‑cap sealing prevents unfiltered water bypass, ensuring all incoming water passes through pleated filter media to obtain stable sediment‑removal performance. It serves as first‑stage coarse pre‑filter to reduce impurity load for downstream water softeners, carbon filters and household water‑using equipment.
Core Technical Specifications
Core Advantages
Efficient 30μm sediment interception:
Pleated polypropylene media effectively traps sand, rust, silt and suspended particles, serves as reliable first‑stage pre‑filter for household tap‑water systems.
Large pleated surface for high dirt‑holding capacity:
Compared with melt‑blown PP sediment cartridges, pleated structure owns larger effective area, extends service cycle and reduces replacement frequency for end‑users.
Standard big‑blue housing compatible dimension:
10‑inch large‑body size fits most mainstream whole‑house filter housings on the market, direct drop‑in installation without any housing retrofitting.
Drinking‑water safe wetted materials:
Food‑grade polypropylene components avoid secondary contamination, suitable for residential drinking‑water pretreatment scenarios.
Economical factory‑direct replacement:
Manufactured by Chinese filter factory. It matches original dimension and filtration performance, helping global dealers and end‑users cut total procurement cost.
Main Application Scenarios
Residential whole‑house tap‑water pre‑filtration for sediment removal
Pre‑protection for household water softener, carbon filter and RO drinking‑water systems
Household ice‑maker, water dispenser inlet‑water filtration
Light‑commercial office building water pretreatment
Small‑size landscape water and circulating water pre‑filtration
Rural well‑water sediment reduction pretreatment
FAQ
Q1: Can HDX4PF4 fit my existing filter housing?
A1: It is standard 10‑inch big‑blue size (9‑7/8”×4.5”). It fits most common 10‑inch large‑diameter filter housings for whole‑house water systems. Please double‑check housing inner dimension before purchase.
Q2: When shall I replace HDX4PF4 filter cartridge?
A2: Replace when differential pressure rises to 2.1 bar (30 PSID), water flow obviously drops, or reaches 30000‑gallon service capacity. Normally replacement cycle is 3‑6 months, subject to raw‑water sediment concentration.
Q3: What is maximum working temperature for HDX4PF4?
A3: Max continuous operating temperature is 82℃. Avoid long‑term hot‑water operation beyond this value to prevent pleated media deformation.
Q4: Are other micron options available for this pleated sediment series?
A4: This series supports 5 μm,10 μm,20 μm,30 μm,50 μm. Custom specifications are acceptable for bulk‑order projects.
Q5: What is production lead‑time for bulk HDX4PF4 orders?
A5: For standard‑spec cartridges, lead‑time is 7‑15 working days upon deposit confirmation. Customized requirements will need extra manufacturing cycle.
