Buyers typically pay $900-$4,500 per HEPA fan filter unit (FFU) depending on airflow, filter grade, and controls; the main cost drivers are CFM capacity, H13 vs H14 filters, and integrated controls or mounting. This article shows practical price ranges and what affects the final HEPA fan filter unit cost.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Single FFU (basic) | $900 | $1,800-$2,200 | $3,800 | Assumptions: 400-800 CFM, H13, basic single-speed motor. |
| High-capacity FFU | $1,200 | $2,500 | $4,500 | Assumptions: 1,200-2,000 CFM, H14, variable-speed drive. |
| Installation (per unit) | $150 | $450 | $1,200 | Assumptions: drop ceiling, 1-2 hours, basic wiring. |
| Replacement HEPA filter | $150 | $350 | $900 | Assumptions: H13-H14 sizes for typical FFUs. |

Hepa Fan Filter Unit Prices for Single Units and Multi-Unit Arrays
Typical total price per unit ranges from $900 for a stripped-down FFU to $4,500 for a high-capacity, variable-speed H14 unit.
Single-room buyers usually see $900-$2,200 for 400-800 CFM H13 FFUs; cleanroom projects with modular ceilings buy arrays where bulk pricing brings unit averages to $1,200-$2,000. Assumptions: standard 2’×4′ or 4’×4′ FFU footprint, basic mounting flange, factory-tested leak rate.
Breakdown of a Quote: Materials, Labor, Equipment, Delivery, Warranty, Overhead
An FFU quote commonly splits into filter and housing materials, fan/motor labor, controls or VFD equipment, delivery, warranty, and contractor overhead.
| Materials | Labor | Equipment | Delivery/Disposal | Warranty | Overhead |
|---|---|---|---|---|---|
| $300-$1,200 (filter, housing, gasket) | $150-$600 (install 1-3 hrs) | $100-$1,200 (motor, VFD, controls) | $25-$150 (shipping per unit) | $0-$400 (extended warranty) | $100-$600 (markup, testing) |
Assumptions: Midwest labor rates, single-story access, standard packaging.

How Airflow (CFM) and Filter Grade (H13 vs H14) Change the Price
Airflow and HEPA grade are the strongest single factors: moving from 400 CFM to 1,600 CFM commonly doubles or triples cost; upgrading H13 to H14 adds $50-$350 per filter and may require a stronger motor.
Examples: 400-800 CFM H13 = $900-$2,200; 1,200-2,000 CFM H14 with VFD = $2,500-$4,500. If target cleanliness requires H14 or higher penetration limits, budget an extra 10%-25% for filter and motor upgrades.
Site Conditions and Installation Variables That Raise the Quote
Tough access, special mounting frames, electrical upgrades, and seismic restraints can increase installed cost by 25%-200% per unit.
Numeric drivers: ceiling aperture size (2’×4′ vs 4’×4′), run length for control wiring over 50 ft (+$75-$250), and required dedicated circuit/transformer work (+$300-$1,200). Cleanroom class change from ISO 7 to ISO 5 may require denser FFU layout and double the units.
Practical Ways To Reduce Hepa Fan Filter Unit Price Without Sacrificing Function
Buy standard footprint FFUs in bulk, choose H13 where acceptable, and opt for centralized VFDs instead of individual drives to reduce per-unit cost.
Specific reductions: order 10+ units for 5%-20% vendor discount, select single-speed for non-critical areas to save $200-$800 per unit, accept reconditioned units at 40%-60% of new price with new filters. Prepare ceiling cutouts and electrical stub-ins to save contractor labor.

Regional Price Differences and How Much They Matter
Expect 5%-20% higher prices in coastal urban markets and 10%-30% lower bids in rural or low-cost Midwest regions.
Examples: average FFU price $2,200 in New York/California vs $1,800 in Midwest; installation labor $75-$125 per hour in metro areas vs $50-$85 per hour in lower-cost regions. Shipping surcharges for air freight can add $100-$600 per unit for expedited delivery.
Three Real-World Quote Examples With Specs and Totals
| Scenario | Specs | Labor Hours | Per-Unit | Total |
|---|---|---|---|---|
| Small lab retrofit | 6× 500 CFM H13 FFUs, basic controls | 12 hrs | $1,200 | $7,800 (units + install) |
| Production cleanroom | 20× 1,200 CFM H14 FFUs, VFDs | 60 hrs | $2,750 | $59,500 |
| Budget clinic upgrade | 4× 400 CFM H13 reconditioned FFUs | 8 hrs | $650 | $3,000 |
Assumptions: Includes basic mounting and testing; excludes major HVAC ductwork or electrical panel upgrades.
