General Questions
Q: Do I need to sit in the same perfect posture all day?
A: Actually, no. You should try to vary your activities and position
during the day to stimulate circulation and rest overworked muscles.
Find a couple of low-risk positions that offer support and comfort and
shift between them. If you plan to do a repetitive task such as work at
your desk for an extended period, many experts feel that you should
take frequent mini-breaks of a few minutes each hour. During these
breaks you could do some filing, sort your mail, do some stretches,
tidy up your office, or walk to the copier and make copies.
Q: What is the best way to organize my workstation?
A: You should keep the most frequently used items within easy arms
reach and on the side of your dominant hand. For instance, if you spend
a lot of time on the phone and are right-handed, you should have your
phone within easy arm's reach on the right side of your workstation.
Avoid awkward reaching, bending, or stretching to reach frequently used
items.
Q: If I work at a computer, how often should I have my eyes checked?
A: A minimum of once every two years. When you make an appointment with
your eye care professionals, you should mention that you work at a
computer and ask if they need any further information. They may want to
know how much time you spend at the computer and how far your monitor
is from your eyes. If you are a heavy computer user, they may offer you
glasses that are optimized for computer work.

Lighting
Q: The amount of glare reduction seems to differ depending upon the workstation. Why is this?
A: At certain reading angles, glare is more noticeable and also more solvable with polarization technology.
Example 1:
Tall person, shallow depth desk, high under-shelf light
Less glare
Less % reduction in glare with PLF
Like glare on water at high noon
Example 2:
Short person, deep desk, low under-shelf light
More glare
More % reduction in glare with PLF
Like glare on water at sunset
Air Cleaners
Q: How do I know if I need an office air cleaner?
A: If you are one of the estimated 20% of the population who suffers
from allergy problems or you are concerned about the indoor air quality
in your area, an office air cleaner can help significantly reduce the
concentrations of allergy-aggravating particles, like dust and pollen,
as well as many other indoor pollutants in your office air. To learn
more about office ergonomics please complete the Workspace Evaluation.
Q: Where can I purchase replacement filters for my 3M™ Office Air Cleaner?
A: Specific distributors, online retailers, and stores are listed for each product.
Q: I have lost my instruction booklet for the OAC100 Office Air Cleaner. How can I receive another copy?
A: To request another booklet, Contact Us.
Q: Can I order refills online?
A: Yes. Information for purchasing refills online is available in the Air Cleaner section of this web site.
Q: What are the specifications on this product?
A: The specifications are available for each air cleaner model.
Q: Is the unit quiet?
A: Each air cleaner has a sound absorbing cushion for ultra-quiet operation.
Q: How many times does it change the air per hour?
A: That depends on the size of the room. Measure your room's length,
width and height in feet and multiply them together to get your room's
volume in cubic feet. The OAC100 cleans 5100 cubic feet per hour and
the OAC200 cleans 7800 cubic feet per hour. Divide the cubic feet of
the air cleaner by the volume of your room and you will have the number
of air changes per hour.
Q: Does your OAC200 Office Air Cleaner mount to wall or sit on table?
A: Both our air cleaners can be set on a table or be mounted to a wall.

Cleaning Products
Q: Can the 675 Screen Cleaner be used on laptop computers?
A: Yes. The cleaning solution and wipes will not harm laptop computer screens.
Foot Rest
Q: How do I know if I need a footrest?
A: If your chair is adjusted to the proper height and your feet aren't
flat on the floor, you should consider using a footrest. Foot rests can
also help individuals who have experienced problems with their lower
backs keep positioned against the back rest of their chair. That way
the chair back, instead of their lower back muscles, is providing the
support they need.

Glare Filters
Q: What is glare?
A: Glare is defined as the light within the field of vision that is
brighter than other objects to which the eyes are adapted. The most
common sources of office glare are from ambient light sources, such as
sunlight from windows and overhead lighting. This ambient light can
shine on the glass front of CRT monitors, reducing contrast and
creating annoying bright reflections.
"First surface glare" is the reflection or washout generated by the
glass surface of a monitor or computer filter. First surface reflection
is only reduced through the use of an anti-reflection coating on the
computer filter or the surface of the monitor. All 3M™ computer filters
have an anti-reflection coating to reduce first surface glare.
"Reflected glare" is the amount of ambient light which passes through a
computer filter, reflects off the monitor face, and passes back through
the computer filter. 3M™ Circular Polarizing computer filters eliminate
up to 99% of reflected glare.
Q: How do 3M™ computer filters enhance contrast?
A: Monitor contrast is how bright the display's characters
(information) appear against the background. Increasing the monitor
contrast makes it easier to read the information being displayed on the
monitor. Contrast ratio (CR) which equals character brightness divided
by background brightness (including the effects of ambient light)
numerically specifies contrast. The larger the contrast ratio, the
brighter the information appears against a dark background. A minimum
contrast ratio of three (3) is specified by the American National
Standard for Human Factors Engineering of Visual Display Terminals.
All 3M™ computer filters improve the contrast by minimizing first
surface glare through the use of an anti-reflection coating. In
addition, all models uniformly filter out ambient light using a neutral
density filter applied to the glass. The "double" filtration of ambient
light as it passes through the filter improves contrast significantly
by reflecting off the monitor and passing through the filter again.
Q: How does the circular polarizing feature work?
A: 3M™ computer filter models HF300 and HF350
are extremely effective light-trapping devices that reduce glare and
increase contrast of monitors. These filters select and alter the
properties of light to more effectively remove monitor glare. The
ambient light that causes glare and reflections is trapped by the
circular polarizer. The light that has passed through a circular
polarizing filter and reflects off a surface, such as a monitor, cannot
return through the filter, and is absorbed by the polarizing layers.
The light from the monitor passes through the filter with far less
reduction in strength. The circular polarizing filter allows the images
from the monitor to pass through easily.
3M™ circular
polarizing computer filters reduce up to 20 times more glare and
improve contrast up to 14 times more than non-filtered computer
monitors.*
* Dependent upon monitor and lighting conditions.
Q: What does "privacy feature" mean?
A: 3M™ privacy filters offer easy, effective solutions to protect
on-screen data. These models feature a patented "microlouver
technology," which prevents bystanders from viewing on-screen data from
either side of a monitor. Only an operator seated directly in front of
the computer monitor can read displayed information. From the side,
passersby see only a dark, blank screen.
The black microlouvers reduce the horizontal viewing area to 60
degrees. The light cutoff provided by the black microlouver is complete
and does not distort or blur images from the monitor.
In addition, 3M™ privacy filters simulate a tiny venetian blind to
shield out unwanted ambient light, thus incrementally increasing the
effectiveness of glare reduction and contrast enhancement.
Q: What radiation issues should I know about?
A: Where it comes from: radiation is generated by the internal
electrical components of the monitor and is emitted from out of the
back and sides of a computer monitor as well as in front. Because of
manufacturer's differences in configuration and shielding of the
internal electrical components, emissions may be greatest from either
direction.
What it is: The type of radiation emitted from computer monitors is not
"radioactive." It isn't as energetic as the type of radiation used by
nuclear power plants. The electromagnetic radiation emitted from
computer monitors is called extremely low frequency (ELF) and very low
frequency (VLF) radiation. All devices requiring electric power will
generate ELF and VLF radiation.
Health risks of ELF/VLF radiation: Studies conducted by various federal
agencies and independent researchers are inconclusive. Although
believed to be nonhazardous, effects most often linked with long-term
exposure to ELF/VLF radiation include miscarriages and childhood
leukemia.
What 3M™ anti-radiation filters do: Both ELF and VLF electromagnetic
radiation have an electric (E-field) component and a magnetic (H-field)
component. When properly grounded, 3M™ anti-radiation computer filters
block up to 99.9% of the electric field (E-Field) ELF/VLF component of
low frequency radiation emitted out of the front of the monitor.
The magnetic (H-field) component is virtually impossible to shield.
Magnetic fields pass through most materials, including concrete, steel,
and lead. The greatest reduction in H-field emission is achieved by
wrapping the internal electrical components with a very expensive
material called mu metal.
All 3M™ filters are tested by an independent laboratory that
specializes in compliance testing. (Laboratory reports are available upon request.)
Using these filters can help monitors meet E-Field ELF/VLF radiation
guidelines and voluntary standards such as MPR-II and TCO.
UV
light emissions: The main source for ultra-violet (UV) light is
sunlight. Insignificant amounts of UV are emitted by a computer monitor
and are related to the emission spectrum of the phosphor and pose no
known health concern for office workers. All glass provides excellent
blockage of UV light. UV light is the invisible region of the spectrum
just beyond the violet end of the visible region of electromagnetic
radiation. It is defined in ranges per ANSI Z87-1-1989:
- UVA Range: 320-400 nanometers
- UVB Range: 240-320 nanometers
- Total UV: 240-400 nanometers
3M™ Computer Filters block up to 96% of the total UV range.
Q: What protection is provided by the anti-static feature on 3M™ computer filters?
A: An electrical charge can build up uniformly over a non-conductive
glass surface, such as a computer monitor. Conductive coatings with
proper earth ground provide a path for discharging this electrical
charge build-up. Almost all 3M™ Computer Filters feature a conductive
coating and grounding cord with clip to provide the path and grounding
mechanism for full discharge of the electrical charge buildup.
3M™ Computer Filters with the anti-static feature discharge an
electrostatic buildup of 5000V in less than 0.1 seconds when properly
grounded. They are independently tested to assure static discharge
performance.
Q: How do I properly ground 3M™ computer filters for the anti-radiation and anti-static features?
A: 3M™ Computer Filters with anti-radiation and/or anti-static features
are supplied with a grounding cord clip. The ground cord must be
connected to the nearest known electrical earth ground in order for
these features to work effectively.
The ground cord clip can be attached to a metal frame on the back of a
central processing unit (CPU), any metal screw on the back of the unit
that makes direct contact with the metal frame, or the metal fan vent
on the back of the CPU. For extra safety, unplug the unit while making
this connection.
Other typical electrical ground locations are electrical conduit, water
pipe, heater vents, and a metal building frame. A small area of paint
might need to be scraped away in order to make better contact with the
metal.
CAUTION: To avoid electrical shock, do not connect the ground cord to
electrical outlets. If you are not sure about grounding the computer
filter, contact a licensed electrician.
Q: How do I clean a 3M™ computer filter?
A: Most 3M™ Computer Filters have Scotchgard™ Protection for Easy Clean
Surface, which makes them simple to clean with just a damp, soft cloth.
To clean the coated glass surface of a filter, remove the filter from
the monitor and place it on a flat surface. Visually inspect the filter
to ensure the glass surface is free from abrasive material. To prevent
fingerprinting, avoid touching the glass surface.
For 3M™ Standard Models and Notebook Models that do not have the Scotchgard™ Protection for Easy Clean Surface, using 3M™ Screen Cleaner 675
is recommended. (For availability of this cleaner, check with the
company from which you purchased the filter.) Spray the applicator with
the cleaner (one pump should be enough.) Reapply if necessary. Wipe
clean and dry with the "Clean Hands" applicator. When the applicator
becomes stained, detach soiled wipe from the applicator by pulling the
outer tab. This exposes a clean wipe. Repeat above cleaning procedure
if necessary.
If 3M™ Screen Cleaner 675 is not available in
your area, use a vinegar-based glass cleaning solution that is 3 parts
vinegar to 7 parts water. Or you might try isopropyl alcohol. Wash with
soft cloth and let dry. If streaking occurs, wash with a vinegar
solution to remove the streaks.

Q: Is your gel patented?
A: 3M™ owns the patent on gel-filled wrist rests.
Q: How do I clean my 3M™ Gel Wrist Rest, AKT Keyboard and Keyboard Drawer?
A: Most minor soiling, including coffee, can be cleaned using mild soap
and water and a damp sponge. For tougher stains such as skin oil,
chocolate and pen marks, we recommend using Scotchgard™ Fabric and
Upholstery Cleaner and a damp sponge.
Helpful cleaning tips:
- Do not use excessive force when cleaning the pad; it could damage the product
- Pen
marks should be cleaned immediately. Marks that are left longer than
one week may not come off. Ink from permanent pens or markers may not
come off.
- When using Scotchgard™ Cleaner, spray it on the stain, let it sit for two minutes, and then wipe it with a damp sponge
- Periodic cleaning may help prevent soil build-up
- On
light gray fabric, darker color usually indicates soiling. On dark gray
or blue fabric, soiling is usually a light or white color. Soiling can
be easily cleaned by rinsing the pad portion under warm water, applying
liquid hand soap and scrubbing with a sponge or tough paper towel.
Rinse and pat dry with a paper towel or cloth. It will dry completely
in about five minutes and look brand new.

Mousing Solutions
Mouse - Ergonomic
Q: Does this mouse come in LEFT hand model?
A: A mouse for left-handed users is not available at this time.
Q: How do I know what size mouse I need?
A: The ergonomic mouse comes in two sizes: small/medium and large. To
determine which size to buy, measure the distance (palm side) between
the outside of your little finger and the outside of your index finger
at the base. If this measurement is 3.5" or less, you should order the
smaller mouse. If greater than 3.5", you should order the larger one.
Q: Is the ergonomic mouse compatible with Microsoft® Windows® XP?
A: Yes, the ergonomic mouse is compatible with a standard Microsoft®
mouse and can be used on most systems that support PS/2® mice and/or
USB. The third button programming will only be available on Microsoft®
Windows® and on other systems. The third button will have a
system-dependent functionality and in some cases, no function.
Q: I need to connect the ergonomic mouse to my serial port – how can I get this to work?
A: You can't. Do not try to use a PS/2® to serial adapter or any other
adapter to connect the ergonomic mouse to a serial port. It won't work
and may harm your computer.
Q: What is the difference between a USB and PS/2® connector?
A: If your mouse has a PS/2® connector, it has a PS driver and needs to
be connected to the compatible hardware device (PS/2® port) in your
computer. If your mouse has a USB connector, it has a USB driver and
needs to be connected to the compatible hardware device (USB port) in
your computer. In both cases, you must also make sure the device is
integrated, so go to the control panel and activate the appropriate
port.
Q: I can't get the third button to work on my MS-DOS® software.
A: The third button functionality is not available in MS-DOS® applications/windows.
Q:
Do I really have to install extra software on my computer to use this
mouse? I'm not allowed to install software on my computer.
A: No, you don't have to install the 3M™ Ergonomic Mouse Utilities. You
will lose the third button programming, but under Microsoft® Windows®
98 and 2000 you will still be able to use it for scrolling in some
applications. Under other Microsoft® Windows® versions you may not be
able to utilize the third button without the Ergonomic Mouse Utilities.
Q: What is the difference between the Short Edition and the Complete Edition of the 3M™ Ergonomic Mouse Utilities?
A: Ergonomic Tips and the User Guide are not included in the Short
Edition. By excluding these parts, the Short Edition is smaller and
quicker to download.
Q: How long will it take me to get used to the 3M™ Ergonomic Mouse?
A: It takes a few days to get used to the mouse. Initially, it will be very different from what you are used to.
Q: What is the warranty?
A: The 3M™ Ergonomic Mouse has a two-year limited warranty. Warranty information is available on-line for each model.
Q: Where can I buy the 3M™ Ergonomic Mouse?
A: To find a distributor, click here.

Notebook Solutions
Notebook Accessories
Q: What are the ergonomic principles that make your notebook platform so comfortable?
A: Most people sit too low in their chair to maintain a straight,
ergonomically correct wrist angle while typing on a notebook. Because
the elbow is positioned below the tabletop, the wrist must bend to use
the keyboard. By tilting the notebook to match the user's natural wrist
position, the wrist is kept in an ergonomically better (non-bent)
position. This tilt also raises the viewing screen so the user does not
have to bend their neck for viewing. The result is a much more
comfortable notebook keyboarding experience.
