Types of Filtration

There are two main ways of filtering your water into a safe useable liquid with the first being physical filtration. Physical filtration is the process of water being strained, which when removes the’s similar to a sieve action which removes particles and impurities from the water as it passes through.

The alternative method of filtering is chemical filtration which works by passing the water over or through an active material which chemically removes impurities and particles from the water. 

Benefits of a Caravan Water Filter

Lightweight Device

Some caravan users use alternative solutions to having clean water, such as bringing bottled water. However, weight and compactness are important considerations for your caravan, and water bottles can be heavy and also challenging to find space on board to store.

A caravan water filter is small and compact, so you don’t need to worry if you have space to store it compared to a bulky water bottle or water container.

Added peace of mind

Worrying about whether you’re going have clean water when you arrive at your caravan park is the last thing you want to be thinking about, especially after a long journey. A caravan water filter offers greater peace of mind that you’ll have access to clean drinking water at all times.

This is even better if you have younger children as it’s one less thing to worry about, and you can focus on enjoying your holiday. Generally, with the best filters, they just require setting up just once and then you replace the filters every so often.

Chlorine taste reduction

It’s not unusual for caravan parks to have a water supply; however, it’s likely to be very chlorinated. Although this chemical is important to treat and remove pollutants, it can give the water a distinctive taste and odour, which isn’t very pleasant.

A high-quality water filter can remove the chlorine levels leaving you with safer and better-tasting water.

Removes contaminants

A high-quality water filter system will remove all the dangerous contaminants from your water supply, leaving you with safer water. Pre-treatment water can contain many dangerous bacteria that can’t be seen with the naked eye such as parasites which can lead to digestive problems which are the last thing you want when you’re trying to enjoy your holiday.

Caravan Water Filter Buying Guide


Similar to any kind of purchase, you need to work out how much you’re willing to pay for your caravan water filter. There are plenty of options that suit a range of budgets. Still, it’s essential to set a budget because this will also limit the choices available to you, which makes the selection process easier than trying to choose from every available product.

Ease of use 

No matter how good you are with caravan systems, you should choose a water filter that is not only easy to set up but also easy to maintain because you don’t want to spend hours trying to set up. It’s also helpful if the kit is supplied with an instruction manual as well as phone or online support.

When it comes to maintenance, you’ll eventually need to replace the filter and the length of time the filter lasts will depend on the filter quality and the amount you use it. You need to ensure that filter replacement is easy to carry out.


As you’d expect, several brands manufacture and sell caravan water filters and just like any brands; some will be more reputable and trusted than others. The brand you choose will also be determined by the budget you’ve allocated as higher quality brands will often demand a higher selling price.  

Selling price is so closely linked to quality if you decide to spend a little more on a better quality product it’ll often have a greater range of features and have a better build quality so will last longer than a low budget product. 


Just like any kind of mechanism, faults can develop with it over time, either due to misuse or purely accidental. For this reason, it’s essential to understand whether your water filter comes with a warranty which will provide you will additionally support from the manufacturer in the form of a replacement or repair should a defect develop. 

The length of the warranty will vary from product to product but serves to give you added peace of mind that you’re buying a quality product. 

Filtering requirements 

The water filter you buy will depend on your requirements, such as the amount of water you plan to filter because you need to choose then a filter that can meet these demands. For example, if you’re using this in combination with a water heater and not consuming the water then the quality doesn’t need to be as high.

Micron Rating

Caravan water filters will have a micron rating, that refers to how the smallest particle size that the kit or system can pass through. A low micron rating will mean that more pollutants and contaminants the filter will let pass through. 


There are several types of water filter that you can choose from with each one having its distinct strengths and weaknesses, and your preferred choice will come down to your personal needs and requirements.

Sediment Water Filter

The sediment-water filter is the most basic version of the water filter and has a mechanism that is most similar to a strainer or sieve. So as the water passes through the particles are caught in the sieve-like mechanism to stop dangerous particles from getting into your water system.

However, this type of filter requires a greater level of maintenance than other competing filters but can form a good starter entry-level solution if you haven’t used a caravan water filter before. If you have a water supply, then at the very minimum you should have a sediment water filter.

Carbon Filter

A carbon water filter takes it one step ahead of the sediment-water filter and is ideal for both casual and serious caravan owners. It not only removes the impurities from your water supply, but it also improves the odour and taste of the water.

The best carbon filters can remove dangerous contaminants such as Lead and Mercury. There are three main types of Carbon filter, which are:

Solid Block Carbon

Solid block Carbon uses activated Carbon which comes in the shape of a block as a result of high pressure. This has a greater surface area compared to granular activated Carbon which means that more water comes into contact with the Carbon, which leads to more effective filtration.

Modified Carbon Block

The modified Carbon block has similar functionality to the solid block Carbon; however, it generates a faster flow rate, so the filtration process is quicker while the Carbon also lasts longer.

Granular Activated Carbon

This is the most affordable type of carbon water filter, and its function by allowing the water to move through small grains of activated Carbon which then removes impurities. However, the main drawback of this type, is that it has a smaller surface area for the activated Carbon which means the filtration is less effective. 

Ceramic Water Filter

You also have the choice of ceramic water filters that have smaller holes which allow for impurities to be filtered out to give you cleaner water. They’re not as effective at removing chemical contaminants such as Lead and Mercury.
