Is a hand dryer better than a paper towel?
Due to the reduction in litter and waste in comparison with paper towels, which cannot be recycled, hand dryers are claimed to be better for the environment. Another study shows that whereas the majority of the environmental impact of a hand dryer occurs during its use, the environmental impact of paper towels is predominantly in the material production and manufacturing stages. It is estimated that hand dryers use 5% less energy than paper towels in the first year, and 20% less over five years. A World Dryer study of 102 hand dryers installed in public schools in Topeka, Kansas, claimed an annual savings of 34.5 tons of solid waste, 690,000 gallons of water, and 587 trees; another World Dryer study of 153 hand dryers in the Iowa state capitol showed an annual savings of 10.5 tons of solid waste and 176 trees. However, a Dutch study published in March 1995 indicated that there was environmental parity between hand dryers and paper towels as hand drying methods when all factors were taken into consideration.
How to choose a hand dryer?
Finding the hand dryer with performance ideal for your facility depends on what features are important to you. Look for Made in USA Certified hand dryers with a warranty you are comfortable with. You may also want to look to products that have been PCR tested which means tested and evaluated in a clear, consistent way, allowing you, the consumer, to make better-informed decisions. Consider how many guests will be using your hand dryer every day. The XLERATOR has an 8-second dry time, making it ideal for busy restrooms where a longer dry time may cause congestion. The XLERATOReco has a slightly longer dry time but has added features to save energy. Compare the models of our hand dryers and find the right fit for your needs with our product comparison chart.
Which hand dryers use room temperature air?
High-speed hand dryers that use room temperature air, like the XLERATOReco, are the most energy-efficient and produce the least amount of carbon dioxide emissions.

How to know if a hand dryer is environmentally friendly?
Not all hand dryers are created equal. To understand if a hand dryer is environmentally friendly, check to see if it has an Environmental Product Declaration (EPD) certification. This is a way of assessing the impact a product will have on the environment through the study of its energy consumption during production, usage, and disposal. The first hand dryer manufacturer to publish verified, third party EPDs was Excel Dryer. Because paper towels generate a lot of carbon emissions and waste, hand dryers are a significantly more sustainable, “greener” option. High-speed hand dryers that use room temperature air, like the XLERATOReco, are the most energy-efficient and produce the least amount of carbon dioxide emissions. An added bonus, Excel Dryer’s high-speed, energy-efficient hand dryers qualify for the most LEED v4 credits of any hand dryer on the market
