But the reality is that once you are on the road, clean and safe drinking and cooking water is a rare commodity for the RV and boating community. And, you never know when disaster might strike (including a natural one), which means backup filters should not only sit in your car emergency kit but also inside of any camping gear put away in storage during the non-travel season too.

How Does RV Water Filter Work

Camco 40043 actually works much like any other RV water filter that uses the 20-micron technology. These RV filters are resilient and durable in their own right.

Their performance is credited to the high-flow sediment and carbon filter, which works in significant propensity, reducing the presence and growth of bacteria in the water it treats inside your RV camper van. Camco 40043 is designed with a wide body, which supports its high flow rate and capacity.

Most RV camper van owners use bleach for their freshwater supply. While this is a standard procedure, chemical compound poisoning is not good for your family in the long term.

And that is why RV camper vans and boats must be at all costs fitted with an under-the-sink RV water filtration system. It makes sure that water used for cooking and drinking is free from chlorine, magnesium, and other pathogenic contaminants commonly found in water.

How long does a Camco water filter last?

Camco water filters are a great way to be sure your family is drinking clean, safe water. The question most people have is how long does a Camco filter last?

In general, the Camco RV water filters can last up to a year. Each water filter is designed to remove impurities from your drinking and cooking water up to 500-25000 gallons before changing the inline water filters.

The official recommendations are to change your water filter three times a year or as soon as the maximum water filtration capacity is reached. Camco water filters are therefore perfect for RVs and boats. 

Camco 40043 vs. Camco 40045 – Which RV Faucet is right for me?

As the benefits of each faucet have been outlined, it might now be easier to decide what your next purchase should be. For those who do not want more than a basic water filter system and prefer simplicity with their drinking water, Camco 40043 is better than Camco 40045.

Camco 40043’s performance is undoubtedly impeccable. If you wonder how long it can keep up its performance before you either replace the Camco RV Filter cartridges, well, according to Camco’s recommendations changing the filter every quarter of the year. 

Changing your faucet water filter every 3-4 months is best to keep the Camco filtration system functioning at the optimal capability possible.

However, in the cases where your RV camper is not in regular use, you can get away with only changing it out every 4 to 6 months.

The takeaway here is that as long as your Camco RV filter averages 18 gallons per day with a burst when using your camper, changing twice a year sounds accurate to the Camco filter cartridge replacement schedule.

Camco 40043 vs 40045

Both Camco 40043 and 40045 are the best-recommended water filtration systems known for being inline with accepted RV’s standard water pressure.

While many of you here would think that an RV water pressure regulator is not a factor in your RV water filtration system, actually, it has a huge bearing. All RVs are fitted with a small but useful device that keeps the psi in check of the water entering your RV, down to a safe level. 

Making sure that your filters are also calibrated to not interfere with the regulated psi is key. And Camco 40043 and 40045 are primed for that.

Though Camco 40043 is seen as being far more superior over 40045 for its hose protector that comes with Camco 40043 as a standard, those who go for 40045 should not panic as the plumbing in newer RVs can handle a 20-micron filter with up to 100 psi. 

Bear in mind that the recommended water pressure for newer RVs is around 60 psi and 50 psi for older ones, so if these two filters can handle up to 100 psi on a 20-micron filter, the hose cover is a minor fix.

As if that was not enough, Camco 40043 and Camco 40045’s resilience and durability are demonstrated in their ability to get rid of pathogens, reduce bad odor, improve water taste, and remove waterborne microscopic sediments, chemical compounds, fluoride, and chlorine in drinking water at a significant rate.

Given an opportunity to recommend one between the two, the one that stands out for me is the Camco 40043. This water filter comes with its own flexible hose protector, and that is a winning combination.

RV Water Filter Replacement Cartridge

The systems themselves are relatively cheap to buy, but the replacement cartridges are expensive. They definitely cost more than most filters for other filtration systems and have a hefty price tag on top of that! For example, it costs an extra $0.12 per gallon just to get fluoride added into your water supply – which will increase the total price you spend each year by about 20%.

  • The filtration process does not stop once the lower chamber is full. So be careful to prevent overfilling.
  • The version does not allow you to check how much purified water is left in the reservoir.
  • You have to lift the top chamber and peek in.
  • Users have complained about the plastic spigot breaking easily.
  • The filtration speed will be slower after using it for so e weeks.


Camco 40043 TastePURE water filter is an excellent inline water filtration product designed to eliminate impurities from your RV or boat. 

The Camco line of products provides filters for many needs, but the most popular seems to be their taste-purifying filtration system that helps make drinking fresh and clean water more enjoyable during long treks through vast landscapes without safe potable sources of H2O nearby.
