Which is better for RV purified or filtered water?

Which is better for RV purified or filtered water

To understand if your RV requires purified water or filtered water, you must first know the difference between the two. Filtered water has been subjected to a series of filtration stages that remove large and total dissolved solids from it. This filtered water is suitable for drinking, washing, cleaning, cooking, and all activities.

Purified water on the other hand is sent via a further advanced purifying process. The highest purity of water might not be essential for simple everyday requirements in your RV unless equipment requires it.

The different types of RV filters available in the market and when to use each of them?

Did you know that there is more than one type of RV filter? Depending on the function and usage, there are several types of RV filters or water filters available in the market today. The following are the types of RV filters that you can make use of, depending on their function and your need.

Sediment filters

We cannot stress the importance of sediment filters in an RV. A sediment filter might either be combined with the RV filter or it can also be installed independently. This is an important addition to the water filtration process. It is natural for campsite water to carry dust, sand, grit, and other larger sediments. Removing these large contaminants is important to protect the RV’s internal plumbing and to prevent any clogs or blockages in the inline water filter.

Sediment filters

Adding a sediment filter before the inline water filter is a wise choice. It protects the durability of the inline water filter and ensures all visible debris (up to 20 microns in size) is removed by the sediment filter.

Carbon filters

Using activated carbon filters is common. Natural elements like coconut shells and charcoal are utilized in a carbon filter. Contaminants from moving water are absorbed by the carbon filter. The contaminants that a carbon filter is good at absorbing are chlorine and chloramine. Heavy metals and volatile organic compounds can also be removed using a carbon filter. The end result is water that is free from contaminants with improved taste and odor.

Carbon filters

UV purification systems

It is important not to neglect the installation of a suitable and efficient UV purification system for your RV filter. UV purification systems are excellent devices to protect water from microorganisms. Protozoa, bacteria, and even viruses can be present in campsite water. These microorganisms carry and spread various infectious diseases. It is, therefore, crucial to making use of an effective UV purification system to kill the microorganisms.

UV purification systems

UV light filters comprise a UV lamp placed within a durable chamber. These UV light filters although do not remove the contaminants from the water, it is designed to target the DNA of the organism and damage it. Once the UV rays damage the DNA, the organism is no longer alive or active. The proliferation of bacteria or viruses is stopped at once. If your RV filter does not have a UV purification system attached to it, it is recommended that you install one separately to ensure your water is free from disease-causing microorganisms.

Reverse osmosis systems

The best type of water filtration is carried out by a reverse osmosis filter. Depending on the model and unit, there are different types and stages within reverse osmosis filters. A highly effective filtration system is a reverse osmosis filter that can remove almost all types of contaminants from TDS, heavy metals, chemicals, and microorganisms. It is wise to install reverse osmosis systems to have access to the pure and clean water supply at all times.

Reverse osmosis systems

Most reverse osmosis systems are larger in size when it comes to RV usage. Typically a reverse osmosis filter is fixed under the kitchen sink. If you are looking for a reserves osmosis filter as an under-sink filter for your RV, you can consider looking for tankless space-saving reverse osmosis filters for your RV.
