De-Mistyfying Goggle Fogging

De-Mistyfying Goggle Fogging

Goggle manufacturers have made great strides in providing fog free vision but fogging is still the predominant complaint when discussing goggles. With that in mind we offer these six tips to keep goggle fogging at bay:

  1. Understand the goggle. Goggle manufacturers approach fog free vision in various ways. 1. No-fog coatings applied on the inside surface of the lens. 2. Vents to allow hot, moist air to escape. 3. Volume. The greater the volume inside the goggle, the greater amount of moist air required to create fogging.
  2. Don’t overdress. This is the # 1 reason goggles fog. You should be slightly cool on your first chair ride of the day. You are going to be skiing and exerting yourself and this will burn calories and generate heat. If you overdress you will be retaining too much heat and this will vent upwards through the top of your jacket and into the bottom of your goggle through the vents. The inside of your goggle is no place for warm moist air since this will inevitably result in fogging. Given the same temperatures, you should consider wearing slightly less clothing on a powder day or layer so that items can be removed when necessary.
  3. Interference between helmet and goggle. Make sure there is adequate space between the top of your goggle and your helmet. Air must vent out the top of your goggle when you stop skiing and if the fit is too close, this will not be possible.
  4. Improper cleaning of your goggle lens. Your goggle lens has a no-fog coating applied to the inside surface. This coating works by absorbing moisture. When the molecules become oversaturated, they swell up and become difficult to see through. If you try to wipe the goggle clean when it is in this state, you will move the coating around on the surface of the lens or you will remove it entirely. If you succeed in moving it around the lens, when it dries, the lens will appear to be scratched. If you remove it entirely, you will no longer have a viable no-fog coating and fogging will occur with greater frequency.
  5. You’ve fallen, now what? If you fall while skiing and your goggles fills with snow, remove the goggle and shake out all the big clumps of snow. Put it back on and ski to the lift. While you are riding the lift, remove your goggle and place it inside your jacket. The warmth will melt any remaining snow particles and the no-fog will absorb the moisture. When you reach the top of the lift, your goggle should be ready to go. If you must remove water droplets from your goggle, dab the water from the lens, do not wipe it.
  6. Blocked vents. When skiing on snowy days you must monitor the condition of the vents on the top of your goggle. As snow accumulates on the top of the vents it decreases the goggle’s ability to vent properly. When you stop, hot air rises and goes out the top vent. If this vent is blocked, the likelihood of fogging will increase.
  7. Avoid the cold start-up. When traveling to the ski area it is important to keep your goggle in a warm place. If you drive to the area with your goggle in the back of your truck or in a box on your roof rack, your goggle will be extremely cold on both the inside and outside lens surface. Your face will be 98.6 degrees and your goggle lens will be zero or colder. Put your goggle on and you get instant fogging. Not a good way to start the day.

The Haber Eliminator™ Automated No-Fog Fan Technology Installation Instructions


The Haber Eliminator is a state of the art instrument, but there are a few things you can do to maximize its effectiveness which will in turn increase your enjoyment and extend the products lifespan.

Care and Use:

1. Do not submerge the Eliminator in water. It is water resistant but not water-proof.
2. Do not subject it to long periods of extreme temperatures. Leaving it in your car overnight and then taking it out on a winter's morning and putting it on your head may cause condensation to form inside the module which could be detrimental to performance. Leaving it on your cars dashboard on a hot summer's day and the resulting high temperatures could cause damage to some internal components.
3. Do not store the Eliminator outside where it could be exposed to extremely low temperatures as frost particles can form in the Fan arena and cause problems at start-up.
4. To clean, wipe with a damp cloth. Do not spray cleaning agents directly on the Eliminator. This could be detrimental to sensors and circuit boards located inside the module.
5. If storing for long periods of time we suggest you remove the battery.
6. The battery has an estimated run life of 15 hours.

Installation Instructions:

You should have received the following parts:

- Eliminator module with battery door attached.
- Top plate with brass retaining nuts attached.
- Owners manual.
- Battery

Steps:

1. Remove the battery door and install the battery.
2. Loosen the two brass nuts and remove the top plate.
3. Take the Eliminator and center it in the upper vent structure inside of your goggle. (There are some supporting ribs in this area and depending on the goggle brand and model you may have to move the Eliminator a few millimeters left or right to avoid these ribs. This is OK and will not affect performance).
4. Gently push the Eliminator so the screws protrude through the vent foam. Check again to confirm that the module is indeed centered or as close to centered as possible.
5. With the screws sticking up through the foam, place the top plate over the screws and tighten the nuts. Do not over-tighten and don't even consider using pliers. You want these nuts snug but not necessarily tight.
6. Look inside the goggle and make sure the Eliminator is fitting in the vent area and not misaligned in any way. It should fit between the front and rear flange of the goggle and should not be crushing one or the other. If it is misaligned, repeat step #5.

Operation:

1. There are three selector positions. a) Off /Red b)Auto/Yellow and c) Always On/Green. Move the switch to the "on" or "Green" position to confirm that fan is working. If "yes" this is good. If "no" check that the battery is inserted correctly.
2. When the fan runs in the "on" position you are good to go. When the switch is placed in the "on" position, it will run continuously.
3. For normal operation we suggest you select the "auto" or "Yellow" switch position. In this position the Eliminator will only operate when needed. It will be fully automatic.
4. There may be days when the Eliminator does not come on at all or days when it runs frequently. This is normal. The Eliminator only responds when environmental conditions require it to.
5. When the Eliminator comes on it typically runs for about 1-2 minutes. However, depending upon the conditions it may run for shorter or longer periods.
6. When you are finished using the Eliminator, move the switch to the "off" or "Red" position.
7. Turn it on when you are using it and turn it off when you are done. It is possible to leave the Eliminator in "automatic" mode while storing it but to preserve battery life we suggest you select the "off" position when not in use.
8. The battery has an estimated run life of 15 hours.


Performance tips:

1. Should you fail to turn on the Eliminator and your goggle fogs up completely before you realize it, you can expect the Eliminator to start working the minute you turn it on but don't expect instant results. The Eliminator works by removing fog before it has a chance to form and it is very efficient at this. It will also de-fog a completely fogged goggle but it may take a little while based on the severity of the situation. The solution is to make sure you turn it on in the morning and off at the end of the day. There is no need to turn it off at lunch if it is set to automatic. Inside the lodge, the ambient temperature is the same on the inside and the outside of the lens, fog will not form and the fan should not come on.
2. The Eliminator works by removing warm moist air from inside your goggle and exhausting it to the atmosphere through the vent foam on the top of your goggle. If snow, mud, or dirt is allowed to accumulate on the top of your goggle it will impede the air flow. Consumers should be diligent about removing particulates from these vents to maintain the full performance capabilities of the unit.
3. Where is condensation (fog) forming? The Eliminator addresses fog inside the goggle lens not on the outside. For instance, if you are skiing and you walk into the lodge, condensation may form on the outside of your goggle lens. The Eliminator will do nothing for this condition since it (Eliminator) is located inside your goggle. The good news is the problem will disappear as soon as the entire goggle reaches room temperature.
4. The Eliminator never came on. When environmental conditions are right the Eliminator will not be needed and it will not come on.
5. It's always coming on. The Eliminator has a humidity sensor. Should the level of humidity exceed the setting for the Eliminator then the product may run frequently. It is an instrument and can only make decisions based on climate. For example; if you are using the Eliminator next to the ocean on a warm day with high humidity it is conceivable the product could run frequently.
6. The humidity is low but it still comes on a lot. Are you overdressed? This is sometimes not an issue in the summer but could be an issue in the winter. If you get to the bottom of the ski run and you are sweating, then overdressing is a consideration. Try removing some layers and see if the problems disappear.
