You need to know your water source and water quality at first.
The key to find a suitable water filter for yourself is to know your local water quality. Most RV sources water from municipal tap water. City water suppliers use chlorine to disinfect municipal water and eliminate waterborne-disease carrying bacteria. However, chlorine can leave water with a chemical taste and smell.
Regardless of the water’s source, if you are in a region of the country with hard water, your RV will be exposed to high levels of calcium and magnesium, which can lead to scale build-up and damaged plumbing.
Waterdrop D4 Reverse Osmosis Water Filtration System effectively reduces chlorine, sediments, heavy metals, bacteria, chemicals, viruses and more, basically any impurities larger than 0.0001 micron. That means this filter can also reduce TDS and soften your water sources. This system is one of the best water filter for your RV.
Also in some RV parks, they use local well water as source. Well water can possess high levels of sediment, heavy metals, and potentially bacteria and microorganisms. If so, we suggest you to install a pre-filter, blocking out large particles initially. Pre-filtered water without large particles travels into RV can protect water-related appliances in your RV.

How does reverse osmosis system work?

The water supply in your home gets in under pressure, irrespective of where you live. Reverse osmosis relies on this same pressure to push water through a semipermeable membrane.
Water passes through the semipermeable membrane under pressure. This leads to the separation of the impurities from the water molecules. The impurities are on one side of the membrane, and the water molecules on the other, with the clean water going to your tap without any impurity whatsoever. There are several filtration stages in the RO water filtration process – up to seven sometimes, and these are responsible for the high purity of water.

Is this reverse osmosis water filtration system suitable for well water?

We do not recommend using well water as source for our RO systems.
The reasons are as follows:
1. Large particles.
Compared to municipal tap water, the well water is rich of large particles, which will clog the filters easily, and shorten their lifetime significantly.Please note that the filters will still need to be replaced more frequently, even if you have added a pre-filtration system.
2. Composition
The well water has very complicated compostion, and some of them (apart from the large particles) can cause the filter or internal valve to be clogged and prevent the RO system from normal performance.
3. Water pressure
The well water may not provide the feed water pressure that the RO system requires (14.5 psi min.). Furthermore, the water pressure will be even lower after passing through pre-filtration systems.

Do I need to have an electrical outlet under my sink for this work?

Yes, the system requires electricity to work. So, an electrical outlet is necessary.

Can I connect the remineralization filter with this reverse osmosis water filter?

Yes, this reverse osmosis water filter works perfectly with a remineralization filter. All you have to do is buy a suitable remineralization filter and connect it to the system. Simply search for “Waterdrop Remineralization Filter” and add the filter.

I just got my RO filter, and it's amazing!

We do not enjoy quality water where I live. After comparing different products, we decided to go for the RO water purifier. It's our first time getting a filter. It's been a few weeks, but the results have been impressive. We got exactly what was advertised on the website. The machine delivers great-tasting filtered water-a huge upgrade to what we used to drink. Our homemade tea, coffee and other drinks taste better. It is also smaller than I expected, and the installation was so easy. As clumsy as I am, I needed no help to install, and it took me less than 30 minutes. What made my purchase decision finally is the composite filter. This is quite different from other ro machines, which consists of several filters. We can save more money and effort by replacing the filters just once a year.
