Classic Pure PPF Sediment Filter Cartridge – 20-Inch Slim, 1 Micron (Stage 1) for Semi Commercial RO Plants
The Classic Pure PPF Sediment Filter Cartridge (20" Slim) brings the same trusted Stage 1 sediment filtration as Axtron's established 10" PPF cartridge, sized for semi commercial RO plants and slim-housing water filter systems that need higher filtration capacity than a standard domestic setup.
This is a slim cartridge — 2.5" in diameter, the same width as the 10" domestic version, doubled in length to 20". As with our 20" CTO and UDF filters, this is built specifically for slim 20-inch housings, not jumbo/Big Blue 4.5"-diameter housings — an important distinction to check before ordering.
Why Stage 1 Sediment Filtration Matters
Before water reaches any carbon or membrane stage, it needs to pass through a fine mechanical pre-filter that catches dust, rust particles, sand, and other visible sediment. This 1-micron melt-blown polypropylene cartridge does exactly that — physically trapping fine particulate matter so it never reaches (and doesn't clog or wear down) the carbon and RO membrane stages downstream. In Pakistan's typically sediment-heavy municipal and borewell water, a strong first-stage filter meaningfully extends the working life of every filtration stage that follows it.
Key Features of Classic Pure PPF Sediment Filter Cartridge
- Slim 20" x 2.5" Sizing — Built for standard slim housings used in semi commercial RO systems.
- 1 Micron Filtration — Fine enough to capture sand, rust flakes, silt, and micro-sediment.
- Melt-Blown Polypropylene (PP) — Food-grade, non-toxic, chemical-resistant, heat-bonded construction with no binders or adhesives.
- 260g Cartridge Weight — Reflects the higher-capacity build needed for semi commercial flow volumes.
- Protects Downstream Filtration — Reduces particulate load reaching Stage 2 (UDF) and Stage 3 (CTO) filters and the RO membrane.
Why Semi Commercial Systems Need the 20" Slim Size
Semi commercial RO plants — schools, clinics, offices, restaurants, and small businesses — handle meaningfully more daily water volume than a home RO system without needing a full jumbo/Big Blue filtration stage. A 20" slim PPF cartridge roughly doubles the filtration capacity of a standard 10" cartridge, in the same housing diameter most slim multi-stage systems already use — and completes a full Stage 1–2–3 lineup alongside our 20" slim UDF and CTO filters.
Applications
- Semi Commercial RO Plants — Schools, clinics, offices, restaurants, and small business water systems.
- Slim Multi-Stage Filtration Setups — Any system using standard 20"x2.5" slim housings.
- Stage 1 Pre-Filtration — Ahead of Stage 2 (UDF) and Stage 3 (CTO) carbon filters and the RO membrane.
Installation & Maintenance
- Install as the 1st stage filter, immediately after the water inlet and before any carbon filtration.
- Typical lifespan is 1–3 months, depending on sediment levels, water source, and daily usage volume — semi commercial systems with higher throughput may need more frequent replacement than a domestic 10" cartridge.
- Ensure a snug, leak-free fit in the housing.
Why Axtron?
Axtron Pakistan has supplied water filtration and RO plant components since 2005, with offices in Lahore, Multan, and Bahawalpur and a network of 500+ retailers nationwide. This 20" slim PPF completes our Classic Pure slim filter lineup — Stage 1 (PPF), Stage 2 (UDF), and Stage 3 (CTO) — giving semi commercial customers a full, matched upgrade path in one place.
Conclusion
If you're running a semi commercial RO plant or any slim-housing water filtration system in Pakistan, the Classic Pure PPF 20" Slim Sediment Filter gives you the same trusted Stage 1 protection as our 10" filter, scaled up for higher-volume use.

12. FAQ Section (add via Rank Math's FAQ block for FAQPage schema)
Q1: What does this filter remove?
A1: Fine dust, rust flakes, sand, and other visible sediment, protecting downstream carbon and RO membrane stages from particulate buildup.
Q2: Will this fit a jumbo 20" housing?
A2: No — this is a "slim" cartridge, 2.5" in diameter, the same width as a standard 10" filter. Jumbo (Big Blue) housings use a 4.5" diameter and need a different cartridge.
Q3: What stage is this used in?
A3: Stage 1 — the first filter water passes through, ahead of the UDF (Stage 2) and CTO (Stage 3) carbon filters.
Q4: How often should I replace it?
A4: Roughly every 1–3 months, depending on sediment levels and usage. Semi commercial systems with higher daily throughput may need more frequent replacement.
Q5: Is this safe for drinking water systems?
A5: Yes — it's made from food-grade, melt-blown polypropylene with no binders or adhesives.
Q6: Do you deliver this across Pakistan?
A6: Yes — Axtron delivers nationwide, including Karachi, Lahore, Islamabad, Rawalpindi, Faisalabad, and Multan, with physical offices in Lahore, Multan, and Bahawalpur.
