Energy Consumption4.0 out of 5
This rating is based on the watts per dry of the hand dryer which is derived from the rated power and the time taken to dry the hands. We have used the figures based on either the manufacturer’s dry time, if yet to be in house tested or based on the in house testing dry time we have conducted. This will also be based on the most energy efficient setting, if the hand dryer is adjustable for speed and/or heat.
Watts per dry:
- 0 – 1.99W = star rating 5
- 2 – 2.99W = star rating 4.5
- 3 – 3.99W = star rating 4
- 4 – 4.99W = star rating 3.5
- 5 – 5.99W = star rating 3
- 6 – 6.99W = star rating 2.5
- 7 – 7.99W = star rating 2
- 8 – 8.99W = star rating 1.5
- 9 – 9.99W = star rating 1
- 10W and above = star rating 0.5
Quiet Sound Level3.5 out of 5
This rating is based on the manufacturers stated sound level, usually at 1m. Please see the section titled "how quiet is the." for more information and independent test results, which give a more accurate noise decibel level. These ratings will also be based on the low noise setting, if the hand dryer is adjustable for speed. Therefore at full speed the hand dryer may not be quiet, however it may be adjustable to become quiet if this is required.
- Up to 68dB = star rating 5
- 69 – 70dB = star rating 4.5
- 71 – 72dB = star rating 4
- 73 – 74dB = star rating 3.5
- 75 – 76dB = star rating 3
- 77 – 78dB = star rating 2.5
- 79 – 80dB = star rating 2
- 81 – 82dB = star rating 1.5
- 83 – 84dB = star rating 1
Life Expectancy3.5 out of 5
This rating is based on the number of motor life cycles (number of uses) the hand dryer, in theory, will last for. This is based on the motor life expectancy given to us in hours, from the manufacturer.
The number of cycles (uses) has been calculated as follows:
(Number of seconds in the hour / seconds per dry) x motor life hours
For a more individualised longevity calculation based on your own usage numbers please use the life expectancy calculator on each product page.
Number of motor life cycles:
- 1,000,000 and over = star rating 5
- 800,000 – 999,999 = star rating 4.5
- 600,000 – 799,999 = star rating 4
- 400,000 – 599,999 = star rating 3.5
- 200,000 – 399,999 = star rating 3
- 100,000 – 199,999 = star rating 2.5
- 80,000 – 99,999 = star rating 2
- 60,000 – 79,999 = star rating 1.5
- 40,000 – 59,999 = star rating 1
- 39,999 and under = star rating 0.5
High Speed4.0 out of 5
These ratings are based on the in house testing we have conducted regarding dry times. They show realistic comparisons of what to expect from each hand dryer. Please note that the manufacturer stated dry time is not always accurate when compared to the hand dryer being used in realistic conditions. The ratings are based on the hand dryer being placed at its high speed setting if it can be manually adjusted.
Dry Speed (seconds):
- 10 – 11 seconds = star rating 5
- 12 – 13 seconds = star rating 4.5
- 14 – 15 seconds = star rating 4
- 16 – 17 seconds = star rating 3.5
- 18 – 19 seconds = star rating 3
- 20 – 21 seconds = star rating 2.5
- 22 – 23 seconds = star rating 2
- 24 – 25 seconds = star rating 1.5
- 26 – 27 seconds = star rating 1
- Over 28 seconds = star rating 0.5
Enhanced Hygiene4.0 out of 5
Hand dryers are a hygienic method of drying the hands. The better the dry, the less the risk of carrying germs on wet hands. Some hand dryers however have gone that little bit further to enhance the hygienic aspects of the hand dryer. These ratings are based on these extra factors that have been added to aid the hygienic properties. These ratings are based on an added together scoring system where the higher the rating the more enhanced the hygienic properties of the hand dryer. Cold Plasma Clean (CPC) is the most advanced hygienic property on the market and scores a maximum of 5 stars.
Enhanced Hygienic properties:
- Cold Plasm Clean Technology = score 5
- Fast dry (<15secs) = score 0.5
- Touch Free = score 0.5
- Heat Sanitation = score 0.5
- UV-C cleaning = score 0.5
- HEPA filter = score 1.5
- Anti Bacterial Coating = score 0.5
- General filter = score 0.5
- Ioniser = score 0.5
Vandal Resistance4.5 out of 5
Some hand dryers would not be suitable for some locations where abuse may be likely such as a train station or night club. However the same hand dryer would be suitable for an office or school location. These ratings are based on an added together scoring system where the higher the rating, the more suitable we would recommend for areas where abuse may be likely.
Vandal Resistance score
- Compact size = score 0.5
- Decreased blockage potential = score 0.5
- Additional Backplate/ fixings strength = score 1
- Anti-vandal extras = score 1
- Metal / ABS = score 1
- Cover thickness 1.5mm or more = score 0.5
- No leverage points (design) = score 0.5
- Deck opening: Ø 35mm
- Rated power: 1 KW (only 0.3w in standby)
- Intelligent temperature control
- Adjustable power, sound and sensor
- Three safety protections
- Smart air outlet design
- Gradient LED light
- Carbon filter
We ask, is it possible to get a balance between speed and noise in a hand dryer that satisfies the user. Of course faster airflow and particularly fast, condensed airflow is going to create more noise, so it’s a real challenge to hand dryer designers and engineers to create a dryer that people are happy with the performance, the noise levels and the energy efficiency,
Blade hand dryers
The Mitsubishi Jet towel is an example of a product that nearly meets this objective. Our independent results* measured the Mitsubishi Jet Towel at 75 dB(A) in a anechoic chamber (sound proof room) with hands placed into the airflow for a realistic noise measurement. 75 dB(A) is considerably higher than the 58 to 64 dB(A) advertised for the Mitsubishi Jet Towel however the generation 8 model dries relatively quickly (around 16 seconds in stringent test conditions, less in normal circumstances) and it uses as little as 0.55kw rated power. 75 dB(A) on a scale using deafening, very loud, loud, moderate, faint and very faint to describe would be on the lower end of loud, very few people would be expected to be irritated by this level.
It must be noted though that this measurement did not take into account noise amplification in a normal room, a previous study at Intertek revealed the Mitsubishi Jet Towel hand dryer measured at 79 dB(A) in a representative room. Upper 70’s in dB(A) are considered to irritate a small minority of people but with a hand dryer it is a very short lived experience, certainly in terms of safety, 80 dB(A) is considered safe for up to 8 hours exposure per day so there is no issue from this perspective. A little more detail about pitch is needed to complete the overview of the perceived sound on hand dryers but from this basic information the Mitsubishi Jet Towel achieves a good balance.
From a hygiene perspective, it has NSF approvals, although these kinds of approvals are done based on testing on brand new hand dryers. What is important is how hygienic the hand dryer will be 2 years after installing. The nature of this hand dryer with its water collection means that it must have a thorough and regular cleaning routine to maintain optimum hygiene standards.
The information we have on the new ‘quieter’ Dyson Airblade DB is incomplete, we only have a measurement in the sound proof chamber at 80 dB(A). You would expect a 4-5 dB(A) amplification in a normal room, if it followed the same pattern as the Mitsubishi Jet Towel and other dryers. Again, there is no safety issue at these levels considering the short term exposure but some users will certainly find these noise levels irritating. The Dyson Airblade DB is certainly fast drying (13-14 seconds in our stringent test and less than this under normal conditions) and uses an acceptable if not low rate power of 1.6kw. We have to say, based on the evidence, if you are looking for a good balance between energy efficiency, speed and noise the Mitsubishi is the overall winner here. With regards to hygiene, the same applies as with the Mitsubishi Jet Towel, all testing is based on a brand new unit, although the Airblade does not collect water if the HEPA filter is not properly maintained and cleaned there will surely be a difference between the hygiene levels provided by a new unit and one two years into its life.
‘Hands under’ type hand dryers.
The Dryflow Classic PLUS and Dryflow Elite are two dryers that are designed specifically to meet the objective of achieving an acceptable performance, at a quiet sound level with reasonable levels of energy efficiency. Another positive is that they are both very affordable hand dryers with outstanding motor lifespans. The Dryflow Classic PLUS is not a super-fast dryer but it is solid, it combines 45 m/s air speeds (traditional dryers 20-30 m/s, high speed 70 m/s upwards) with heat to achieve an approximate 20 second dry. The independent test measured the dB(A) at 72 in a sound proof chamber with hands under and because the Dryflow Classic PLUS is not relying purely on rapid airspeed we would expect amplification in a normal room to be minimal. We would describe this hand dryer as an excellent compromise, reasonable fast if not spectacular, with a very tolerable noise level with a rated power of just 1.35kw giving an energy efficient, if not hyper low energy performance. The Dryflow Classic PLUS is vandal resistant, very long lasting and at a price point where it is affordable for all. I guess the only question mark is that mild heat, in theory will increase bacteria levels if the dryer is not internally sanitized, we don’t have any clear evidence of this put this is the argument that has been pu forward by the paper towel companies for many years.
The eXtremeAir CPC hand dryer
The eXtremeAir CPC is a new innovation in the hand dryer market, this product contains a Cold Plasma generator that effectively creates a reaction from the moisture on the hands and in the air to form hydroxyl radicals that break down the molecular structure of bacteria and small viruses present on the hands, in the immediate surrounding air and surfaces. The eXtremeAir CPC has a completely adjustable motor and heat settings hence why it is included in this discussion.
On maximum speed the dryer tested at a relatively high 86 dB(A) with hands in the airflow, however it reduced to just 73 dB(A) on the lower setting. It is worth noting that at the lower dB (A) level it still had a motor speed of 14,000 rpm and airflow comparable, if not a little faster with the Dryflow Classic PLUS, so with this hand dryer you can find the balance to suit. The eXtremeAir CPC uses as little as 0.3kw on minimum motor speed and only 0.5kw on high motor speed. When you need it to be quieter, you can reduce the motor speed down and add heat. The issue of heat creating bacteria is negated by the cold plasma. Cold plasma is also self-sanitising in the sense that it continuously sanitises the surface of the hands, surrounding surfaces and inside the dryer, so we can say with assurance that the product remains as hygienic 5 years into its life as when it was first tested.
The eXtremeAir CPC is a genuine breakthrough in the market and we believe can be evidenced as the best current solution that can be described as potentially quiet, very hygienic (more so than any other method of drying in fact), very fast and energy efficient. It is also guaranteed for 6 years and highly vandal resistant so we think ticks all the boxes.

When you rent a hand dryer, we will provide the installation, on-site breakdown cover and a yearly service check. The rental contract would be over a minimum 3 year contract (usually 5 years) and paid for by monthly direct debit.
All quotes are subject to a credit check and typically 3-6 months payment will be taken in advance to cover the install. We can only quote (without a site visit) if you have existing electrical spur points in place.
The hand dryer remains the property of 'Intelligent Facility Solutions Ltd' after the rental period and may either be extended, removed or purchased for a much reduced fee.
Renting hand dryers is an option that allows your business to avoid capital expenditure and reduce upfront costs on purchase and fitting. It also gives service backup and breakdown cover. Hand dryer rental agreements are a minimum of 3 years on hand dryers due to installation cost involved. Alternatively you may wish to buy hand dryers outright and reduce overall payments.
We always suggest you speak with us about your facility before deciding whether to buy or rent hand dryers. In many locations, rental will mean you are paying far more in the long run than is necessary, particularly as good quality hand dryers should last for many years without problems and if there is a rare breakdown, it will be a lot cheaper to have a service call, as a free unit will be provided within the guarantee. However you may just prefer lower monthly payments, particularly if you are used to rental or buying paper towels.
For public sector organisation's there is funding available for interest free loans for our energy efficient models which means it makes more sense to buy the product outright in most instances.
Most organisations can write off the value of a hand dryer in the first year of purchase so there is no depreciation necessary for accountants to worry about. If the hand dryer is on the ECA list then all organisations can write off the value in year 1.
Have a bulk order to place? Please contact us to see if we can provide you with further discounts based on quantity of units required.
We provide very competitive discounted prices to wholesalers, trades and organisations such as charities and the public sector. So if you are looking for a contractor price for a project coming up, or you need a hand dryer for a community location such as a scout hut, please contact the relevant department below.
