Caravan Ventilation: How to Eliminate Unpleasant Odours

If you enjoy caravanning or exploring Australia in an RV, you’ll know all about the joys of the open road and the genuine freedom that this type of leisure travel provides. If you have had the misfortune of owning a poorly ventilated caravan, you will also know how persistent and pervasive bad odours can be in an enclosed living space. Today, we’re tackling this thorny issue head-on as we turn the spotlight on caravan ventilation best practices. If unpleasant odours are spoiling your caravan experience, we have the answers you seek.

Keeping Your Caravan Fresh: How to Prevent Odours with Good Ventilation

As you will have guessed by now, good ventilation is the key to eliminating unpleasant odours in caravan and RV interiors. There are several other ways that you can mask bad smells temporarily, but without adequate air circulation, none of these ways will be effective in the long run. In addition to improving air circulation in your living space, well-designed ventilation systems lower humidity, which can be a source of bad smells in itself if not dealt with. Overly humid conditions encourage the growth of mould that, in addition to smelling bad, can cause or aggravate a variety of respiratory conditions.

Here’s how you can optimise the ventilation in your caravan or RV:

• Roof Vents – Installing new roof vents or upgrading existing ones with high-quality exhaust fans will help improve the airflow in your caravan. Exhaust vents can also be used for spot removal of odours: install one in your kitchen area, and the smell of stale oil will no longer be the canvas on which all your travelling memories are painted.

• Windows – Opening windows on opposite sides of your caravan is a simple way to generate more airflow and is an odour-elimination strategy that almost every caravan enthusiast can take advantage of. Even if you have no roof vents, exhaust fans or other ventilation gadgets installed, you can use this trick to quickly fill your caravan interior with fresh air.

• Interior Fans – Invest in some good-quality RV fans and position them in strategically chosen locations to encourage air circulation in your caravan on still days. Well-placed interior fans can also be used to vent cooking odours faster when used in conjunction with open windows or roof hatches.

• Dehumidifiers – If you frequently travel in humid conditions, you may like to consider investing in a portable dehumidifier for your caravan living space. By reducing moisture levels in the air, you will help prevent mould and mildew from growing in your caravan’s interior.

In addition to improving the ventilation in your caravan’s interior, we recommend spending a few minutes thinking about the most common sources of unpleasant odours in caravans so you can eliminate them at source.

Common Sources of Caravan Odours

If you identify and eliminate the most common sources of unpleasant odours in your caravan, your ventilation system won’t have to work so hard. In our experience, the following are all common causes of bad smells in caravans and RVs, and all can be mitigated with a little time and effort:

• Moisture/Humidity –  As you might expect, excess moisture is more of an issue in humid areas and at certain times of the year. However, it can quickly become an issue in poorly ventilated enclosed spaces, no matter the time of year or destination. All the ventilation improvements we suggested in the previous section will help ensure that excess moisture is not a problem you have to worry about in your caravan or RV.

• Cooking – Small caravan kitchens, especially those with inadequate ventilation, are the source of many unpleasant odours in caravans, but the solution is usually quite simple. Adding an overhead vent with an integral exhaust fan solves most caravan kitchen odour issues in short order. If you don't want to install a new vent, consider cooking outside more, and when you do cook inside, try not to fry.

• Dirty Laundry – Failing to keep up with your laundry while travelling can quickly lead to unpleasant odours. Fortunately, the remedy is simple: do your laundry more often and store it in an airtight container.

• Bathroom Chemicals – Some chemicals used in caravan toilets may cause unpleasant odours. The most effective solution is to install an exhaust fan in a window or roof vent. You could also try using a different brand of chemicals to see if it makes a difference.
