| Scenario | Method | Basis | Base dose | Factors | Schedule | Estimated liters |
|---|---|---|---|---|---|---|
| Renovation corridor | Surface | 180 m², 2 zones | 12 ml/m² | Medium, Normal, 1.10 safety, 5% wastage | 1/day × 10 days | ~5.0 L |
| Enclosed waste room | Fogging | 55 m³, 1 room | 10 ml/m³ | High, Tight, 1.20 safety, 8% wastage | 2/day × 7 days | ~2.0 L |

This calculator estimates deodorizer volume using a base dose and site adjustment factors:
Adjusted(ml/app) = BaseDose × IntensityFactor × VentilationFactor × SafetyFactor × (1 + Wastage%)
Total(ml) = Adjusted(ml/app) × ApplicationsPerDay × Days
Total(L) = Total(ml) ÷ 1000
PacksNeeded = ceil( Total(L) ÷ PackSize(L) )
Choose a dosage rate that matches the product label and your application method.
- Select a calculation method that matches your deodorizer use.
- Enter area, volume, or source count, plus number of rooms/zones.
- Set your base dosage rates based on your product guidance.
- Adjust intensity, ventilation, safety, and wastage for site conditions.

Where deodorizer planning matters on construction sites
Deodorizers are commonly used during demolition, refurbishment, waste handling, drain works, and fit-out activities where odor complaints can pause work. A quantity plan helps you keep treatment continuous, especially when access windows are short and schedules change. Estimating liters from a defined basis (area, volume, or point sources) reduces over-ordering while protecting productivity.
Selecting the right dosing basis
Choose surface dosing when deodorizer is sprayed or wiped over floors, walls, or porous materials. Use fogging when a mist is applied to air volume in rooms, shafts, or enclosed storage spaces. Point-source dosing fits bins, skips, drains, sumps, and localized hotspots where a fixed amount per source is repeated. If you do not know the basis, start with the method that matches your application tool.
Adjustment factors and site variability
Real consumption is driven by odor intensity, ventilation, and operational buffers. Higher intensity (active waste, stagnant water, strong VOCs) usually needs a higher factor. Tight or poorly ventilated rooms can require extra product to achieve coverage. Add a safety factor for uncertainty and a wastage allowance for overspray, residue, and container losses during changeovers.
Packaging, rounding, and cost control
Convert the total milliliters into liters, then into packs based on the container size you purchase. Rounding up prevents stock-outs; showing fractional packs helps budgeting when you can share drums across zones. If you enter a unit cost, the calculator provides a simple spend estimate for procurement comparisons and for tracking planned versus actual consumption.
Worked example data set
Use this example to validate your inputs before ordering:
- Method: Surface • Treated area: 240 m² • Rooms/zones: 2
- Base dose: 14 ml/m² • Odor intensity: High • Ventilation: Normal
- Safety factor: 1.15 • Wastage: 8% • Schedule: 2/day for 7 days
- Pack size: 5 L • Unit cost: 40 (currency as selected)
1) Which method should I use?
Pick surface for spray/wipe coverage, fogging for air misting by room volume, and point dosing for drains, bins, or hotspots. Match the method to how the product is applied on-site.
2) Should I use area input or dimensions?
Either works. If you already know the treated area or volume, enter it directly. If not, enter length, width, and height to estimate a consistent basis for planning.
3) What safety factor is reasonable?
For stable, repeatable work, 1.05–1.15 is common. Use 1.20–1.40 when access is limited, site conditions vary, or you expect higher-than-normal odors and interruptions.
4) Why does ventilation increase quantity?
Tight areas can need higher dose to reach effective coverage. Very airy areas may disperse product quickly, so a modest increase helps maintain control between applications.
5) How do I choose a base dose rate?
Start with the product label or supplier guidance. If you have no reference, use conservative planning ranges (for example 5–30 ml/m² or 2–15 ml/m³) and refine using observed consumption.
6) Can I estimate cost accurately with this tool?
It provides a planning estimate based on pack price and rounding. Actual spend can change due to wastage, rework, delivery minimums, and changing odor intensity during the project.
7) What should I record to improve future estimates?
Track treated area/volume, method, dose rate, number of applications, weather/ventilation, and actual liters used. Compare planned versus actual to calibrate factors for similar jobs.
