“What is the best water filter for my caravan?” is question we always get asked. And when looking at the many different water filters available on the market, it comes as no surprise that many travellers are left scratching their heads in confusion. To help filter through the options and steer you in the right direction, we have put together this definitive guide so that you can find the best water filter for your needs, quick and easy. Once you see what each type of water filter does, you will be able to make a more informed choice when making a purchase. But before we start, let’s first look at the different considerations that should be factored into your purchase decision.
Should I Filter All or Only Some of The Water?
For many travellers, the need to filter only some of the water entering their caravan is a popular choice. Typically, the water that should always be filtered is the water that you will consume. When it comes to water used to operate the toilet and shower facilities, many people choose not to filter this.
However, there are many contaminants found in the water in parts of Australia that can have an adverse reaction even when not consumed. Pesticides and parasites can be found in some waterways and these can irritate the skin or enter the body via the mouth while washing. For this reason, it is always a good idea to filter as much water as possible, especially the water used for cleaning dishes, washing your hands and body and for drinking.
Having a rough idea of how often you will use a water filter will help you choose the right size filter for your requirements, too. If you only intend on using it a couple of times a year, then a basic water filter system should suit your needs.
Where Are You Getting Your Water?
Every water supply is different and some water supplies need more filtration than others. Will you be using chlorinated town water or will you be using untreated river or bore water? Does the area have hard water?
What Contaminants May Be In The Water?
Sediment, rust, algae, bad taste, odour, chlorine, cysts parasites, giardia, cryptosporidium, bacteria, scale, heavy metals, fluoride or softening are just some of the contaminants that can be removed. Some water filters are better than others at filtering out these different contaminants.
What Is A Water Filter Micron Rating?
A micron rating is the size of the particles that a water filter is capable of removing. 1 micron is equal to 1/1000th of a millimetre. Therefore a 5 micron filter will remove contaminants that are 0.005mm and larger.
What Does Flow Rate Mean?
Measured in litres per minute (LPM), the flow rate of a water filter in the measurement of how many litres of water can pass through the filter per minute. The higher the LPM, the more water the filter can process.
How Long Will A Filter Last?
Don’t put too much value on the total filtering capacity specification of any given filter. The life of a filter is totally dependent on the quality of the water you’re filtering. The more contaminated it is, the faster your filter will become blocked and the sooner it will need cleaning or replacing.
How Much Space Do You Have?
How much free space do you have available for installing a water filter and where would you prefer it to be? Knowing how much free space you have available will help you select a water filter that is of an appropriate size and purpose, or whether you may need to use two water filters in conjunction with each other.
Think about the size of your cupboards and cabinets. Is there adequate space inside of these where you can discreetly install your water filter? Perhaps you would prefer to install it above or under the main sink? Taking a few measurements of the height width and depth of these spaces will help you choose the perfect size water filter.
