Factors To Consider To Get Best RV Water Filtration System

1. Type

If you often go for a trip in your RV, then choosing a reliable water filter is important to make sure you always have enough clean water to use. There are different types available on the market now and you should be aware of each product’s capability. 

If you want a basic item that can filter sediments and particles, go for an inline or sediment filter. Or check the canister type, it can be customized according to your requirements. 

2. Installation

I recommend you choose a filter which is easy to set up and you don’t need to spend too much time on this. The manufacturer should give you detailed and clear instruction to do this by yourself. And if you want to replace your filter, it should be with ease too. 

3. Micron rating 

The micron rating is a number that shows you how small the particles can pass through this system. The smaller the number is, the more efficient and reliable the filter works. It means more pollutants and contaminants will be get rid of your water. 

4. Size

How much water do you need for your RV? Depending on your need, you can decide the amount of water that you need to purify. And bear in mind that a bigger filter can provide a more powerful flow of water. This decides how fast your water will run.
