How To Stop The Helmet From Fogging Up
Helmets are essential and devices that users of motorcycles cannot do without. They are to be used at all times and need to be taken care of well. The problem with these devices comes about when the weather changes and becomes a bit colder.
In colder weather helmets are very likely to fog up and cause problems to the user. This is a very small problem but one that causes a lot of headache to users and one that has to be solved as soon as possible.
This article goes into details of this problem and attempts to provide solutions that should ensure comfort at all times.
Cause Of The Problem
Fogging is a very basic problem that comes about because of the effects of the atmosphere. When the weather grows cold, the temperature of the air also goes down. Lower temperatures affect everything around them.
The glass that makes up the visor is not left behind; it becomes colder and because of this becomes a surface in which condensation can take place easily. The user in cold weather will have his breath at a higher difference in temperature to the glass of the visor.
This temperature differential is the main cause of condensation. The breath condenses and becomes vapor hence interfering with the visibility of the helmet. The more a user breathes, the more condensation happens, and the more impairment is to be expected.
The problems caused by impaired visibility are hardly something that we have to spend a lot of time on. With low visibility accidents definitely will occur, and the user is putting himself in huge risk by continuing to ride in these conditions.
A solution, therefore, is of utmost importance and one that cannot be overlooked. Below we will look at various strategies that users can employ to rid themselves of this menace.
Solving the problem of frosted windows is not such a big deal. Some measures can be employed, but all these measures can fall only under many broad groups. The groups are the following:
Ventilation involves the allowing of air to penetrate the device. By allowing air to come in the helmet is balanced concerning air temperature.
The difference between the temperature outside and inside is minimal, and therefore chances of condensation occurring are very minimal. Ventilation can be accomplished by leaving gaps in between the visor and outside. This method has its risks however and sometimes is not recommended.
Instead of allowing outside air into the helmet the user can choose to employ water repelling as the means of choice to counter fogging. Water repellents are chemical products that can be applied to the mirror and when this is done act to prevent any water from forming on the visor.
Water vapor is essentially water and so by doing this, the user ensures that it is possible to keep the visor free of vapor. This is a very good method, and most of the methods that fall under this group are well encouraged.
Maintaining Visor Surface Temperature
The last group of methods involves keeping the temperature of the visor surface constant. By keeping the temperature constant there will be no temperature difference, and condensation will not take place. This minimizes the chances of the helmet fogging.
All these methods are very good and below we will get into the specifics that a user can apply for himself.
Actual Methods Of Preventing Fogging
There are five methods discussed below. They are all full proof though there are users who will obviously prefer some to others. The choice ultimately is theirs.
Keeping The Visor Open
This is one of the basic methods and unsurprisingly one that is often overlooked in comparison to the others. It involves allowing a small portion of the visor to stay open.
This allowance is very important, and it allows air from outside to come into the helmet thereby evening the temperatures and preventing fogging. The visor is usually held in place by a notch.
This notch can be withdrawn and the thin arc left open for air outside to come into the visor. Another means would be to tie a cable around the chin. This method is applicable when the visor used cannot be opened or has not been designed to be pried apart.
There is a downside of course to this method, and it involves the chilling of air inside the helmet. Users who can withstand the chilly conditions that will be brought about by the method should look for other means to keep the visor free of moisture.
Alternatively, the user could choose to employ other means to keep the visor clear of all fog. This will involve increasing the ventilation. The ventilation works by allowing air circulation to take place.
This motorcycle helmet is usually an almost totally sealed area. This sealing occurs to keep the helmet safe and prevent interaction with the outside world which could cause problems with the control of the bike.
Ventilation makes the air breathes out by the user to find alternative paths out and not just depend on the visor. There are a lot of means that can be employed to keep the ventilation system open and usable. The most obvious involve opening all vents.
When the vents are open, it is rather obvious that air will get in and cause the exhaled air to find a way out. This makes the interior of the helmet virtually free of exhaled air.
There is another method that involves using a nose guard. The nose guard is a device that can be worn over the face and through it, air can be redirected and made to follow a path that is different to the one it would have taken normally.
The air is directed downwards and expelled from the helmet. This also keeps the helmet free of exhaled air. The user could also choose to have a removable lower chin skirt piece. This is a device which makes the lower part of the helmet open and allows for increased air flow. More air results in better ventilation.
Lastly for the more radical users, they could choose to ditch all neck buffs and thereby open the lower part of the helmet. This also facilitates air exchange.
Use Of A Pin Lock
The pin lock is a device that can be bought with minimal funds and used to ensure that no fogging takes place on the visor. It is like a second visor that has to be fitted on the interior of the real visor.
It is clear, so it will still allow the user to see the road clearly. The visor is very much like double glazing and works in the same way. In between the original visor and the pin lock is a thin film of air. This air is most vital as it prevents the visor from fogging up. It is Warmer than the air outside and therefore keeps the temperature of the visor up. This prevents any cases of fogging. The advantages of this method are obvious and do not have to be dwelt on.
A small issue might occur with the fitting process. The user should know that not all visors have fitting pin locks. The locks are designed for specific helmets, and there are helmets whose pin locks are very hard to find.
Also, the fitting process requires some expertise, a user who is not experienced might damage his or her visor while adding the pin lock.
Fog Stopping Technology
Some products can be used and these I have collectively put under the banner of fog stopping technology. These technologies are quite similar to the pin lock but also have their differences. Pin locks require bolts to work and be fitted properly.
This means that there is an additional cost and also they might not fit in the helmet properly. These fog stops are very different. They require no fitting, no bolts, and can be put on the visor and left to be.
They are much easier to handle and much more flexible as one does not depend on the size of the helmet or visor. Some companies manufacture these products, and the brand names include Respro fog mask, raleri fog stop, and others. These can be easily purchased and used.
The last method we are going to deal with has to do with water repelling. When nothing else works, or the other methods of preventing fogging appear to cause more problems than they solve, the best way then would be to use water repellants. Some approved products can be used as water repellents.
Water repellents work by making the visor unattractive to water. No water droplets or even moisture can be on the visor once the repellent has been applied. These products must sometimes be applied.
They typically wear off with time and the user has to use them again and again whenever there is need. The best strategy would be to apply the repellant whenever you want to go out on the motorbike.
This way you can be sure of your safety. The process of application is very simple and will not cause any problems at all. Simply coat all parts of the visor with the repellant and then put on the helmet. You should be safe after this. Common repellents include the following: Carnauba wax, fogtech ( brand name), muc-off anti fog, shift it anti fog.
