When you are travelling with your family or even alone, you need to take care of a few things. One of the most important of these things is the quality of drinking water.

The Problem

As we already know that travelling in an RV is famous across the country. The problem arises when you consider the quality of drinking water on your trip. You cannot take enough water bottles to last for the whole trip. You cannot rely on water pitchers or gravity water filters as they have a limited capacity and are very slow in filtering water.

Best Reverse Osmosis Water Filter for RV

10. iSpring RCC7AK 6-Stage Superb Taste High Capacity Under Sink Reverse Osmosis Drinking Water Filter System with Alkaline Remineralization-Natural pH, White

Filtration Capabilities: It is one of the most powerful water filtration systems currently available in the market. It has 6 stages of water filtration. The first 3 filters are pre-filters that remove sediment, VOCs, chlorine taste and smell, chloramines, and other harmful chemicals. These 3 filters make your water better and save the RO membrane from getting damaged. The next stage is the RO membrane, which comes with a 0.0001-micron rating and only allows water molecules to pass through. It also removes the healthy minerals from water, which are re-added in the next stage of re-mineralization. When the water leaves the filter, it is healthy, all the minerals have been restored, and there is no smell and taste in water.

Filter Replacement: The system uses 6 stages of filters, and hence you need to replace 6 filters. Each filter has a different lifespan. The first three filters work well for 6-12 months. RO membrane needs to be replaced after a couple of years, and the re-mineralization filters last for 18 months. The replacement time is greatly impacted by the amount of water filtered and the quality of water. Please keep in mind that maintaining large systems is costly.

Installation and Technical Details: The major concern while buying a RO system for your RV is the installation space. It needs a lot of space under the sink, and you must make sure that you have enough space to install it safely. You can also go for a countertop installation with some modifications. Everything needed to install the system comes with it. You may need professional help for installation in case you are not aware of the plumbing connections. It can handle a feed pressure of 45 PSI – 70 PSI and temperature between 40 – 100 °F. It can handle a maximum TDS of 750 PPM.

Tank Capacity: The pressurized tank capacity has a capacity of 3.2 gallons, and it can hold 2.5 gallons of water at one time.

Buying Guide

Buying guides helps you in making the best purchase and get the most out of it. If you are not aware of all the features you need in your RV water filter, you are most likely to end up with the wrong product. We know that you have vague ideas about your products. We have just jolted all the features at one place to advise you in selecting the best water filter for your RV.

Type of the Filter

The type of filter is based on a couple of factors. One factor is the point of installation, and it depends upon the source of water filtration. Second is the quality of water you are filtering. Let’s look t the types now

Inline Water Filter – An inline water filter system fits directly to the entry point of your RV. It filters all the water supply entering your RV’s water tank. It is capable of removing a variety of contaminants like suspended particles, chemicals, bacteria, and other pollutants from the water.

External Water Filter – An external water filter processes the water outside of your RV. The primary difference between the installation of an inline or external water filter is the installation location. External water filters remove suspended particles, chemicals, and other harmful contaminants from your water. They help maintain a cleaner tank and keep the stored water fresh.

Under Sink Water Filtration – An under sink water filtration system is installed inside the cabinet under your sink in the RV. They have different filtration capabilities depending upon the type of filtration media installed in them. One disadvantage of using such types of filters is that they occupy a lot of space under the sink and may reduce your under-sink storage space. They are, however, better in terms of filtering the water.

Reverse Osmosis RV Filters – If you have large space inside your RV kitchen cabinet, you can also go for a reverse osmosis water filtration system. They occupy more space than simple under sink water filters but produce better water in terms of purity. They are also costly, and only a few people prefer to install them. Depending upon the specifications of the particular model you are buying, you would need to supply a small amount of electricity to them as well.

Amount of Water to be filtered

Another important factor to consider is the amount of water you will be filtering from your water. Calculate your estimated travel and the volume of water you and your family consume on the trips and then get a water filter. If you have to change water filters on your trip or face slow flow rate and clogged filters, what’s the point of having a filter in the first place? Your filter should last for a long time and accommodate a large number of trips without any replacements.

Supply Source

Another factor to keep in mind while buying an RV water filter is the source of water. If you are using external sources of filling the fresh water tank, then an inline water filter or under sink or RO system will work best for you because the quality of water can be compromised, and we don’t want you to compromise on your health.

Cost

It is always better to estimate the cost you are going to incur on the RV water filtration. Despite the initial cost, you would have to pay for the replacement filters and maintenance. Single filter systems are easy to maintain as compared to RO filtration systems. RO systems do provide a better quality of water. Make sure you purchase a filter that is in your budget, and you can afford it in the long run as well.

Installation and Space

A good filter is easy to install. Do not end up buying a filter that needs professional help for installation or may leak during your trip. Inline filters have an increased risk of leakage during trips. Make sure the filter you are selecting is easy to install, user friendly, and does not have any working issues. You also need to make sure that your RV has enough storage space for the filter. This is more relevant when you are opting for an under the sink or RO filtration system.

Benefits of RV Water Filters

RV water filters bring along the following benefits

• Hygienic drinking water
• Convenience (easy to use, install and replace filters)
• Enhanced taste and smell of water
• Most of them are compact and lightweight
• Saves money by avoiding clogging in water pipes and buying costly bottled water

Conclusion

We have explained everything in detail related to RV water filters. You don’t need to go anywhere else after reading our guide. Select the filter that suits your needs the best, install it, pack your luggage, and hit the road with peace of mind about drinking water.
