Hand Dryers vs Paper Towels: Cost Comparison, Hygiene & Sustainability
Cost comparison of hand dryers and paper towels in commercial facilities
The choice between hand dryers and paper towels isn’t just about convenience — it impacts costs, hygiene, sustainability, and user experience across your facility.
- Paper towels: Higher long-term supply and disposal costs, generate waste, often perceived as more hygienic.
- Hand dryers: Higher upfront investment, lower running costs, reduce landfill, but raise concerns about noise and aerosolisation.
Facilities managers must weigh:
- Traffic volume (hundreds vs thousands of daily uses)
- Occupant risk profile (healthcare vs office vs school)
- Brand and sustainability goals
- Maintenance and labour availability

Quick Cost Comparison: Hand Dryers vs Paper Towels
- Paper towels: ~$3,500–$4,500 per restroom per year (consumables, labour, waste)
- Hand dryers: ~$600–$800 per year (electricity, maintenance, amortised purchase)
- Typical savings: ~$3,000 per restroom per year at ~500 uses/day
- Payback period: 12–24 months for most commercial facilities
Cost Comparison — Hand Dryers vs Paper Towels
For most facilities, cost is the deciding factor. While paper towels appear inexpensive, ongoing supply, disposal, and labour costs quickly add up. Hand dryers require more upfront investment but typically deliver major long-term savings — especially in medium to high-traffic facilities. Here’s how the numbers compare.
How Much Do Paper Towels Cost to Operate?
On average, a commercial hand dryer uses 0.004–0.005 kWh per use, making electricity costs negligible compared to paper towel consumption.
Modern high-speed hand dryers typically cost less than $100 per year in electricity and include energy-saving features such as motion sensors, automatic shut-off, and low-wattage or unheated air settings.
Breakdown example (2 kW unit, 12 sec per dry, 500 uses/day):
- Purchase & installation: $900 amortised over 5 years = $180/year
- Electricity: 500 × 0.0045 kWh × $0.12 × 365 = ~$99/year
- Maintenance: ~$200/year
Total estimated annual cost: ~$680/year
At 500 daily uses, switching to hand dryers can save ~$3,000 per restroom per year.
For most medium-traffic facilities, the upfront cost of a dryer is typically recovered within 12–24 months through eliminated paper, waste, and labour expenses.
Cost Verdict: Which Is Cheaper Long Term?
- Paper towels carry high and escalating recurring costs
- Hand dryers offer predictable, low operating expenses
- At moderate usage levels, dryers deliver clear long-term savings
How Much Do Hand Dryers Cost to Operate?
On average, a commercial hand dryer uses around 0.004–0.005 kWh per use, making electricity costs negligible compared to paper towel consumption.
Modern high-speed hand dryers typically cost less than $100 per year in most commercial bathrooms. They also include energy-saving technologies such as motion sensors, automatic shut-off, and low-wattage or unheated air settings.
- Breakdown example using 2 kW unit, 12 sec per dry (medium-traffic facility using 500 hand dries per day):
- Purchase/Installation: $900 installed, amortised over 5 years = $180/year
- Power Cost : 500 uses x 0.0045 kWh/use × $0.12/kWh x 365 days = $99/year electricity
- Maintenance: ~$200/year
- Total Costs: $683/year
In practice, the true operating cost of paper towels often exceeds $4,000 per restroom per year — even before accounting for bin liners, delivery, or storage space. That makes paper towels one of the highest recurring expenses in a commercial washroom budget.
At 500 daily uses (roughly a medium-size office, school, or community centre), switching to dryers could save around $3,000 per year per restroom.
The initial cost of a dryer is quickly offset by the elimination of paper, waste, and labour expenses. Over a five-year period, most facilities achieve full payback and enjoy substantial ongoing savings.
Lifespan and Maintenance
Over the long term, hand dryers have a clear advantage in reliability and upkeep. A quality commercial dryer typically lasts 7–10 years with minimal servicing — far outlasting paper towel dispensers that require daily restocking, storage space, and regular waste removal. The reduced maintenance load can also free up cleaning staff time for higher-value tasks elsewhere in the facility.
Hygiene & Safety: Which is More Sanitary?
Hygiene debates around drying methods are highly contested, with industry-funded studies often reaching opposite conclusions. Drying is just as important as washing for effective hand hygiene, but the method you choose makes a difference. Different processes carry different risks: paper towels physically remove bacteria, while some air dryers can aerosolise droplets. In facilities with strict infection control standards, this choice can affect compliance as well as health outcomes.
Paper towels
- Physically remove bacteria and moisture from hands.
- Preferred in hospitals, labs, and food-prep environments.
- Often mandated by regulations in clinical or food-handling spaces.
Hand dryers
- Older warm-air dryers can aerosolise droplets, increasing airborne bacteria near the unit.
- Modern high-speed dryers with HEPA filters capture 99.97% of particles ≥0.3 µm, reducing this risk.
- Sensor-activated operation limits surface contact.
Key takeaway:
- In hospitals and clinical settings → paper towels are safest.
- In schools, offices, and public washrooms → efficient dryers with HEPA filters are generally acceptable when well maintained.
Risk-mitigation tips if using dryers in sensitive areas:
- Choose HEPA-filtered dryers.
- Position units 1.5–2 m away from sinks to avoid splash contamination.
- Enforce regular filter replacement (6–12 months) and cleaning schedules.
- Offer hybrid options (both towels and dryers) in high-risk zones.
Sustainability — Environmental & Waste Impact
When comparing the environmental impact of hand dryers vs paper towels, lifecycle studies consistently show energy-efficient dryers produce less waste and lower emissions over time.
With schools, councils, and corporates under pressure to hit sustainability targets, the environmental impact of washroom choices is no longer secondary. The difference between single-use paper waste and energy-efficient dryers is significant — and lifecycle assessments (LCAs) provide clear evidence of the long-term carbon and waste implications.
Lifecycle Assessments (LCA):
- University of Melbourne: Found hand dryers had lower overall impacts across most categories than paper towels.
- Global studies (MIT, Dyson, Excel): Conclude efficient dryers outperform towels on greenhouse gas emissions and solid waste, especially on low-carbon electricity grids.
Carbon footprint per dry (global averages):
- Paper towels: 5–30 g CO₂e
- Warm-air dryers: 10–50 g CO₂e
- High-speed dryers: 2–15 g CO₂e
Waste impact:
- Paper towels: ~5 g per use (adds up to hundreds of kg/month in high-traffic facilities).
- Hand dryers: negligible waste, burden comes from electricity + one-time manufacturing.
Bottom line:
- In Australia (with an increasingly decarbonised grid), efficient dryers are usually the greener option.
- Paper towels remain viable if your facility has composting or waste-to-energy disposal available.
User Experience & Operational Factors
Even when cost, hygiene, and sustainability align, user experience can make or break washroom strategy. Noise levels, accessibility, and system reliability all affect whether people actually use the dryers — and whether your janitorial team can keep restrooms running smoothly. Here’s what to consider.
Noise
- High-speed dryers: 75–95 dB (brief but noticeable).
- Warm-air dryers: 60–70 dB.
- Paper towels: <50 dB.
- Consider quiet models for libraries, clinics, or spaces serving children with sensory sensitivities.
Reliability & Availability
- Paper towels: Stockouts, dispenser jams, overflowing bins.
- Dryers: Mechanical failures, vandalism risk.
- Hybrid setups: Reduce risk and improve user satisfaction.
Accessibility
- Paper towels: Preferred by some users for control and quick use.
- Dryers: Sensor-activated, no manual pulling — easier for wheelchair users.
How to Decide — Choosing What’s Right for Your Facility
