Things to Consider
If you want to enjoy high quality water when you’re enjoying an RV vacation, then a water filter should be considered essential kit. However, with so many different filters on the market, it can be a little tricky to make a purchase decision. So, here we’ve compiled a buying guide with the things to consider and answers to some common questions to help you find the best model for your requirements.
Benefits of RV water filters
Having easy access to proper water filtration is important for campers and RV owners that spend time outdoors on a regular basis. For this reason, many people install a water filter to improve the quality of the incoming water supply. Installing an RV water filter delivers a number of benefits that include, clean water for preparing food and bathing, lighter and more compact compared to carrying a water tank and simple to set up in any camping venue.
Features to consider when choosing an RV water filter
Here we’ll explore the features to consider to help you narrow down your choices and find the best one for your needs.
Amount of water to filter
One of the key considerations when choosing any type of water filter is the capacity.
Knowing how much water you are planning to filter will help you to make an informed purchasing decision. There are many types of water filters on the market and the volume of water they can filter can vary a great deal from one filter to the next. If you want to filter all of the water coming into an RV it’s advisable to choose a product with a sediment filter.
Type of filter
There are different types of water filters available and many water filtration systems include multiple filter types. Some filters are more effective at removing sediment, others are good at removing certain times of contaminants and some are excellent at providing a little polish at the end to make the water taste better. When you choose a water filtration system for your RV, it’s a good idea to understand the types of filters available. Some of the common filter types that you will come across, include:
Sediment Filter: This is always the first stage in a multi-stage filtration system and it’s designed to remove larger particulates.
Sediment such as sand, grit and dust, can foul up the internal components in a water filter and introduce turbidity into the water supply. This results in maintenance and water quality issues in your camper or RV.
A sediment filter also protects the water pump, toilet valves, water heater and the faucets from damage. So every RV owner should make sure that their chosen water filter has a sediment filter. The CLEARSOURCE Premium RV Water Filter System has an excellent 5-micron sediment filter to remove these contaminants.
Carbon Filter: Some carbon filters such as the Camco EVO Premium Water Filter can remove a wide variety of contaminants from the incoming water, including: asbestos, heavy metals and volatile organic compounds (VOCs). Most modern filters can also remove chlorine to improve the taste and odor of the water making it cleaner and more palatable. There are three main types of carbon filter used in RV water filters, they are:
Granulated Activated Carbon (GAC): This is an inexpensive and effective way to filter incoming water and it’s based on a tried and tested method that’s been used for millennia. Essentially, the water is passed through a set of tiny carbon grains that have a large surface area in relation to their size. Any contaminants adhere to the surface of the carbon remaining trapped there until the filter cartridge is replaced.
Solid Block Carbon: This carbon filtration media consists of pulverized activated carbon that is formed into solid blocks under high pressure. Compared to GAC a solid block has an even greater surface area for the activated carbon to filter the water effectively. This media prevents the water from forming channels into and through the carbon to maintain contact and filtration efficiency.
Modified Carbon Block: The final type of carbon filtration media is the modified carbon block which is similar to the solid block carbon media. But, modified carbon block filters are designed to improve the flow rate and they last longer than the other two types of carbon filter media shown here. For this reason, a modified carbon block filter is the most expensive option.
Ceramic Filter: This water filter is a ceramic unit with a series of small holes in the casing that allows the filter so screen out contaminants, such as: bacteria, giardia, cysts, protozoa and sediment. This type of filter is not very effective at removing chemicals and it’s often paired with some type of carbon filter to meet this need. This is a good filter type for users that are concerned about biological contaminants in the incoming water supply.
Reverse Osmosis: This type of water filtration is achieved by forcing water through a semi-permeable membrane under high pressure. The contaminants are left on the surface of the membrane and flushed away periodically to avoid clogging the system. This system will block any particulates that are larger than a water molecule and the water simply passes through. This technology is becoming common in many people’s homes but the best RV reverse osmosis water filters are still extremely expensive.
Easy installation and replacement
When you choose an RV water filter it makes good sense to choose a system that’s easy to install and the cartridge should be easy to replace.
A filter cartridge would typically last for around 3-12 months. depending on the exact model installed
When it comes time to change the filter it needs to be a simple hassle free process so you can get back to your vacation quickly.
Although a filter should last for 3-12 months before it needs replacing it’s advisable to replace it every 3-6 months anyway. This will help to keep the filter fresh and ready to use after extended periods when the water filter has not been in regular use. There are water filter models that can last for 12 months and these should be changed every 9-12 months to stay on the safe side. It’s a good idea to monitor the water output periodically to see if the taste has changed or the water is darker or sediment is visible. If this occurs, change the filter cartridge immediately and always have a spare on hand for this purpose.
There are sediment filters rated at 5.0 microns to filter out larger particulates above that size. Other RV water filters may be rated at 1.0 or even 0.5 microns for even finer filtration to make the water even cleaner. Some of the cheaper water filters such as the Camco 40045 TastePURE Inline RV Water Filter have a 20-micron sediment filter.
There is a tradeoff to consider, the larger the water filter, the more apertures and the better the water flow will be. So if you choose a smaller filter the flow can be restricted and it will be necessary to purchase larger canisters to compensate. Over time a water filter can also become clogged with sediment or other contaminants to create water flow issues. Replacing the filter should correct this problem and the water flow should improve.
Since you will need to change the filters periodically, it is important that it is light enough so that you can comfortably change it. If you have limited mobility or other health issues, you may prefer to opt for a model that may not offer extended filtration, but the cartridges are easier to change.
How to install an RV water filter
Whole RV Filtration (185)
This type of filtration system filters all of the water coming into the RV and it can attach directly to the vehicle via the intake hose or it may be installed inside the RV. These types of systems are divided up into one, two or three canisters. The more canisters there are the better the filtration will be, but more canisters take up more space. Some whole RV filters such as the AQUACREST RV Inline Water Filter are “inline” systems. These filters use a single canister, they are an ideal system for occasional use and dedicated RV enthusiasts need to think about more comprehensive systems.
Under Sink Filters
These simple water filters attach to a line that runs under the sink and they only filter the water that is supplied to that single sink. These water filters are available in a number of different sizes just like other filters mentioned in this article. Because these filters are installed under the sink it’s important to think about the size carefully. Space under the sink will be at a premium and certain RV models do not have easy access to these areas. This type of water filter is fine for occasional users that want cleaner water for drinking and cooking.
These types of filters are similar to the under sink filters mentioned above, but as the name would suggest they are installed on the countertop directly to the tap. This saves space under the sink but it does mean that the user will have less countertop space which can create other issues.
Typically, RV water filters last between 3 to 12 months, depending on the specific product and brand. However, it is advisable to change your filter every 3 to 6 months, or every 9 to 12 months for filters that can last up to 12 months.
This impressive system not only offers comprehensive filtration, but is ready to use straight out of the box. The product is specifically designed for RVs and campers with easy to use connectors that can have your filtration system up and running quickly, eliminating bacteria, chemicals, microorganisms, particulates and even chlorine from your water supply.
