There are many different styles, types, and sizes of filters on the market for RV use. Picking the right one can take some time, and you may be a little bit concerned that you’ll end up with the wrong one. However, with a little planning and thinking, you should be able to choose the perfect filter for your needs right away from the list of high-quality products above.

How can you know a filter is right for your needs? Are there ways to narrow down your options, or are they all more or less the same? Here are a few ways you can tell:

  • Choose how many canisters of filtration you need. The more canisters, the more well-filtered the water will be. However, your RV may not have the space for larger filter systems, or they may be too strong depending on how you’re planning to use them. Picking the right size for your RV is a crucial step.
  • Choose which pollutants you want to filter out of your water. For example, most filters will handle chlorine and fluoride, but not all of them will take care of nitrates or sediments. By choosing the level of filtration and the types of contaminants you’re concerned with, you’ll be able to better narrow down your options and find a good filter for your RV.
  • Be sure to check on the flow rate. Some filters may slow down your flow rate considerably, and this can be a pain when you’re already dealing with the lower water pressure in an RV or at a campsite.

In the end, you’ll need to make the final decision for which filter to use for your RV based on your specific needs and the goals you have in mind. If you’re traveling on your own, you can probably get away with a smaller sized filter that doesn’t process quite as much water in a day. On the other hand, if you’re traveling with your family, you’ll need to think bigger. And if you have a baby, be sure to pick a filter that can handle nitrates, too.

Once you have the right filter in mind, your RV experience will be that much safer, healthier, and better-tasting, too!
