PURE UV | Replacement String Wound Sediment Filter

Protect your PURE UV Water Purification System with the PURE UV 5‑Micron Replacement String Wound Sediment Filter—your essential first stage in ensuring clean, sediment-free water for drinking, cooking, and household use.

• Deep-depth sediment trapping from 5 µm and larger particles: sand, silt, rust, debris

• Extends life of downstream UV lamp & carbon filters by removing damaging particles upfront

• Professional-grade polypropylene string-wise wound design ensures consistent performance

• Designed specifically for PURE UVB & UV‑20 under-sink systems—maintains full flow & efficiency

For use in the following PURE-UV Water Purifiers:

• PURE UV-2 Under Counter 3-Stage Ultraviolet Water Sterilizer (stage 1)
• PURE UV-3 Under Counter 4-Stage Ultraviolet Water Sterilizer (stage 1)

Key Advantages

1. Multi-layer depth filtration

The wound string structure captures coarse particles on the outside and finer sediment deep in the core, reducing clogging and extending filter lifespan .

2. Reduces system repairs & costs

By pre-filtering sediment, it preserves delicate RO membranes, UV lamps, and carbon filters, minimizing frequent replacements and service calls.

3. Long-lasting & dependable

Typical service life is 8–12 months, with higher quality water extending longevity to 12 months—check flow rate to know when to replace.

4. SIMPLE drop-in replacement

Standard 10″ × 2.5″ (or for UV‑20, 20″ × 2.5″) dimensions make installation a breeze. No hassle, no extra tools.

5. Warranty‑safe with PURE filters

Using non‑PURE filters voids PURE UV warranties—keep your guarantee intact by using genuine replacements.

Ideal Use Cases

• Tap or well water with visible cloudiness, sand, rust, or particles

• Households with frequent plumbing wear or sediment-related issues

• PURE UVB2/UVB3 and UV‑20 systems as the Stage‑1 pre‑filter

• Preventing expensive damage to UV lamps and downstream filters

Product Features

• 5‑micron nominal rating: Balances efficiency with flow

• Food-grade polypropylene: BPA-free, chemically inert

• Depth-grade winding: High sediment capacity, low pressure drop

• Temp-safe design: Operates reliably at typical household water temps

• NSF-standard construction: Meets industry norms for potable water safety

Frequently Asked Questions

1. How often should I replace the filter?
Generally every 8–12 months. For high-flow UV‑20 systems, replace every 3 months to ensure optimal performance.

2. Is it compatible with my PURE UVB2 or UV‑20?
Yes—10″ × 2.5″ for UVB systems, and the 20″ version for UV‑20 units operating at 15 GPM.

3. What does “5‑micron nominal” mean?
It traps about 85% of particles ≥ 5 µm—a standard, effective level for sediment pre-filtration.

4. Can I use a cheaper generic?
We strongly advise against it. Generic filters may void PURE UV’s warranty and risk damaging the system—use only official PURE UV filters.

5. My water is cloudy—will this help?
Absolutely. It's layered construction removes varying sediment sizes, restoring clarity and protecting your system.
