RV Water Filter Reviews: the Ultimate in Portable Water Purifier Technology?

RV owners should never leave home without one of these RV water filters.

If you're worried about the quality of water that comes from your home city, then imagine how difficult it's going to be to ensure clean, pure drinking water while you're on the road!

Fortunately, you can choose from a wide variety of portable water filter systems, specially designed to save space in the cramped quarters common to most RVs.

While "big name" RVs, such as Airstream and Winnebago, can supply RV water filters either out of the showroom, or as an aftermarket upgrade, you don't have to pay top dollar from a dealership to get pure drinking water in your RV. Most popular RV purifiers and RV water softener systems will fit easily into any RV.

Culligan RV-600A RV Water Filter: How It Works

The filter makes use of granular activated carbon which provides an efficient method of eliminating the bad taste and smell from your water. In addition, it can also filter out particles or sediments such as sand, silt, lime scale, dirt and other impurities.

When using the filter, it is also recommended that you join it to two flexible hoses if possible, to prevent it from damage.

All you have to do is remove the plastic plugs found on both ends of the RV water filter. Save those plugs for days when you might need to store the filter. The outlets on the filter are both labeled, so simply attach the inlet to the hose and flush it for around five minutes. Should you decide to use a second hose, simply attach it to the outlet end of the hose to extend.

Culligan RV-600-A RV Water Filter: Pros and Cons

Ease of Use:  no tools are necessary for installing this filter. The filter installs inline with the hose, so all you have to do is connect it to the hose, back flush, then connect it to your water source. This filter is disposable; it also is very easy to break it down and store it when winterizing your RV

Quick Fill: The filter works best with a high flow rate, giving you roughly half to one gallon per minute. It can filter up to 2500 gallons on a single filter before needing a change

Five-year Warranty: Culligan been around for many years, so you can be certain that they give the best they have to offer. NSF certified, it can be used all year round, but if for some reason your filter housing has problems or doesn't live up to your expectations, this warranty will cover you

Hose may be too short: the length of the hose may be a problem, especially when it comes to RV connectors and the weight of the filter. The weight tends to pull the filter out; you may need to have a pressure of at least 40psi at first to have a good water flow rate inside your RV

Culligan RV-600-A RV Water Filter: Conclusion

You can't get fresher or cleaner water for such a reasonably-priced filter (under $20 on Amazon at the time of our review).

With a quick flow rate, you could provide your boat, trailer or motor home with quality water in no time at all.

You may need to buy an extension hose, but this does not affect how your water will flow or the pressure it has.

It's certainly splitting hairs to complain about a hose (cost around $3 from a large hardware store) when this is such a reasonably-priced addition to your RV.

Culligan is one of the biggest names out there. Highly recommended.

Camco 40651 RV CX90 Ceramic Water Filter

Read reviews of the Camco 40651 RV CX90 Ceramic Water Filter at Amazon

In this day and age, water sources can be very unreliable, especially in public grounds, parks, and campsites.

When your RV hits the road, make sure it is equipped with a powerful water filtration system, like this Camco RV CX90 Ceramic Water Filter.

It ensures clean and safe drinking water for you and the whole family. This RV water filter comes complete with a hose, cleaning pad, and wrench set for easy fitting.

Camco 40651 RV CX90 Ceramic Water Filter: How It Works

This unit is installed to the exterior point of water entry to your RV. Setup and installation is fairly easy. It's important that you read the instructions carefully; prime the filter after connecting it to the water supply for your RV.

The Camco CX90 features a Granulated Activated Carbon (GAC) and KDF filter media with ceramic barrier. It stops contaminants down to 0.9 microns, to provide premium protection against chlorine, sediments, heavy metals, cysts, fungus, and mold. The KDF carbon core also helps eliminate bacteria and unpleasant taste and odor as well. Impurities are removed, or at least reduced to a minimum amount, so water cloudiness is also greatly reduced.

The element might require frequent cleaning, especially if the water is not that clear. You can extend the filter's life by using the cleaning pad included with the product. Just make sure not to over-clean the filter, so it will last as long as advertised.

The filter element can be fragile, so bringing along a replacement is recommended, especially if this filter is the only source of drinking water for the duration of your trip.

Camco 40651 RV CX90 Ceramic Water Filter: Pros and Cons

Solid design: the housing is made from a high-grade, unbreakable, UV stabilized polycarbonate resin, to ensure long-lasting durability

Long life: the filter's recommended usage is up to one year before it needs to be replaced

Field serviceable: the filter can be easily serviced for full filter recovery. The clear canister lets you see when the filter needs cleaning. Use the wrench set provided to pop the filter open. Simply take the filter out of its housing, and give it a gentle scrub using the included cleaning pad

Filter element issues: the removable filter is very fragile. It can break easily when not handled with care

Requires regular cleaning: the filter can become really dirty within just a week of use. Without regular cleaning and maintenance, the flow rate will significantly decrease

Camco 40651 RV CX90 Ceramic Water Filter: Conclusion

The Camco RV CX90 Ceramic Water Filter is a great choice if you want to upgrade the quality of your RV's water supply.

It has amazing cleaning properties that give it an edge over competing brands, especially at this pricepoint (sub-$60).

Its biggest plus is the fact that it can be cleaned while on the road, as needed, to fully restore the flow rate and keep the water clean and pure.

The filter element is good for one year before having it changed; replacement cartridges are available at a very reasonable price.

Probably the biggest drawback of this filter is the fragile nature of its ceramic element. But as long as you handle it with care, you won't have issues at all. While it's true that the filter accumulates dirt in a very short period of time, it only shows how well the system works to filter impurities and other unwanted elements out of the water.

Highly recommended, excellent value for money.

Whether you are on the road or on the campgrounds, Culligan EZ-Change RV Drinking Water Filtration System is a great solution in ensuring healthy and great tasting water supply to you and your family.

Simple to install and easy to use, this water system filters the water of your RV to make it safe for drinking, cooking, and more.

This RV water filtration system comes with: filter head with built-in bracket, replacement filter cartridge, bypass fitting for winterization, mounting screws, supply adapter, faucet with cartridge-life indicator, quarter inch plastic tubing, filter-change reminder sticker, and user's guide, for an unbeatable price!

Culligan RV-EZ-3 RV Water Filter: How It Works

The system utilizes a level III advanced filtration process that eliminates cysts, such as cryptosporidium and giardia, sediments, lead, chlorine, turbidity, and many other harmful chemicals and impurities, making your water not only taste great, but smell pure and fresh as well.

This RV water filter system features a winterization kit. This ensures that your filter is protected from dipping temperatures, whether your RV is on the road or parked for winter.

Installation is fairly easy. It takes no more than an hour to get everything done. Use the screws for mounting the head and quarter inch plastic tubing for the input and output lines. There is a third small center screw in addition to the two keyhole screws on the housing. This screw adds more stability, by keeping the filter housing from being accidentally dislodged out of its mounting screws when replacing the filters.

The built-in electronic cartridge-life indicator is a great feature of the system. It tells you when the cartridge needs to be replaced. Installing the battery in the insert behind the faucet activates the indicator light.

Culligan RV-EZ-3 RV Water Filter: Pros and Cons

Ease of use and maintenance: Culligan's instructions are very straightforward; setting this up on any RV is a breeze.

Affordable: the unit and the replacement cartridge are very reasonably priced, especially when compared to some other RV accessories!

Tested and rated: this product is marine-rated for maximum efficiency. It is also certified by NSF to provide safe drinking water supply

Slow flow rate: this unit is specifically made for RVs, so the water pressure is not as high as you would expect from a whole house water filter. The flow rate is just around a quarter gallon per minute. Greater flow could have been achieved by making a larger filter surface area and bigger diameter tubing

Culligan RV-EZ-3 RV Water Filter: Conclusion

For the ease of use, maintenance, and reasonable price, the Culligan RV-EZ-3 RV water filter is hard to beat.

It is a great upgrade to your inline RV water filter system so you can enjoy a cleaner and healthier water supply, no matter how skanky the water is where you're camping.

Truly excellent value for money from a company renowned for producing some of the best house water filters.

Camco 40645 RV TastePURE: How It Works

If you have problems regarding chlorine, rust, sand or silt in your water, then this filter will really help you out. The filter generally improves the taste, smell and smell of your water, because it can filter medium-sized sediment and other particles.

The filter also uses activated charcoal filters, which remove the contaminants in your drinking water and highly improve the smell.

One thing to note is that you don't want any carbon to get into your water system. When setting up the filter, make sure that you let the water run through it for a couple of minutes to remove the carbon lines.

You will know that the filter is ready to use when the water flow finally becomes clear.

It is generally recommended that you turn the faucet on halfway for a minute, then turn it on all the way after a minute has passed, when you flush the system in this way.
