Benchmark SureAir Replacement Prefilter

The B5200-PRE is the replacement prefilter for the B5200 SureAir PCR Workstation, sold at $55 ($280 less than the main HEPA at $335). The prefilter is the first-stage filtration component that captures larger particulate before it reaches the main HEPA filter, extending main-HEPA service life by catching the bulky particles that would otherwise load the more-expensive HEPA prematurely.

For full chemistry rationale (HEPA / prefilter replacement cycle, filtration system design), see the B5200-FIL (main HEPA filter) parent page.

Key Specifications

Prefilter vs Main HEPA: Replacement-Cycle Economics

The prefilter does the heavy filtering work, replaced 4–8× more frequently than the main HEPA but at ~16% the cost. This protective-filter strategy maximizes main-HEPA service life by catching the heavy-particulate load before it reaches the expensive main filter.

Replacement strategy:

• Prefilter every 3–6 months at facility scale
• Main HEPA every 1–3 years as needed

Skipping prefilter replacement compromises main-HEPA service life, false economy.

Ordering & Configuration

Pair with B5200 chassis. The prefilter is workflow-incomplete without a chassis.

Plan ongoing inventory. Maintain prefilter pack inventory at facility scale (more-frequent replacement cycle benefits from in-house spare inventory).

Confirm at quote: chassis pairing, replacement-cycle plan, and lead time.

Warranty: Per Benchmark Scientific standard consumable terms.

SureAir filter family:

- B5200-FIL, Main HEPA filter ($335), 1–3 year replacement cycle

- B5200-PRE (this product): Prefilter ($55), 3–6 month replacement cycle

Pick the prefilter for routine first-stage filter replacement; sister main HEPA replaces less frequently. See B5200-FIL anchor for full filter-family rationale and B5200 anchor for full SureAir workflow detail.
