How To Get Rid Of Stale Damp Indoor Air

A damp home can cause you untold suffering as you breathe in stale air which is quite uncomfortable. In addition, you are at risk of developing respiratory complications. Asthma can be triggered in a damp environment and you can also develop allergies. Dust mites develop in moist conditions and they can cause itchiness of the eyes and a runny nose.

You can also develop eczema when the dust mites get into contact with your skin and in case you already have eczema, then the condition will be worsened. In case you have children or an old person in the home, they will be more at risk. An effective sub floor ventilation system will help rid your home of all these risks.

Sources Of Damp In The Home

There are several reasons why your sub floor could be experiencing excess moisture levels. It could be that there are pipes that are leaking and causing the ground to be wet. It could be that there is a garden that is adjacent to the sub floor and the water seeps into the ground when the garden is watered. A very heavy storm followed by periods of very high temperature can also cause the sub floor to have excess moisture content.

Lack of sufficient cross flow can cause the sub floor to be damp. It is important to check whether there is anything that is obstructing the flow of air such as abandoned items and get rid of them. The vents that are in the sub floor could be too small to provide sufficient ventilation or they could be too few in number. A ventilation expert can access your sub floor to give you a solution that will provide you with sufficient ventilation.

Sub Floor Ventilation Requirements

Some experts recommend that in order to have sufficient sub floor ventilation, the air in the sub floor should be exhausted at least five times in every hour. There are different fans in the market which exhaust different amounts of air per hour.

In order to get the right fan, you need to know the total volume of your sub floor area. You can get this area by multiplying the length, width and height of your sub floor in meters cubed. You can then multiply this result by five to know the amount of air that is to be exhausted per hour. You can then purchase a fan that exhausts this amount of air per hour.

Exhaust Fans

Most mechanical sub floor ventilation systems use exhaust fans to get rid of stale moist air. Supply fans that push in air into the sub floor can also be used but the risk is that the stale air can be pushed upwards into the house rather than outside. This can further complicate the problem of damp in your home. An exhaust fan will expel the stale moist air to the outside thus removing the risk of the air rising up to the house.

Fans have different capacities and features. There are fans that have a timer so that you can control the number of hours that the fan will be running. It is a good idea to run the fan during the day when it is hottest outside and the humidity levels are low.
