Caravan Water Filters             

While the subject of whether a caravan needs a water filter rages on in the caravanning world, there’s no doubt that a considerable amount of people like to know that the water they’re drinking from their caravan site is of good quality.

Some caravaners prefer reassurance that when they are away from home, more so when they travel overseas, the water source they’re using is safe to drink. Many people feel the differences in the water available on the main tap in a caravan park, compared to that back home, are too apparent and therefore prefer to remove the chlorine taste from it and any possible unpleasant odours they feel are present in the current supply.

Overall, the decision of whether to place a water filter in your caravan usually boils down to personal choice. However, there’s no denying that having a clean supply of fresh drinking water on tap throughout your stay in the van is indeed a bonus and one less thing to worry about each time you pull up to a different site.
