Reviews of the 6 Best Reverse Osmosis System for Well Water

1. Whirlpool WHER25

Whirlpool Wher25

Whirlpool WHER25 Review: Best Countertop Reverse Osmosis System for Well Water

Whirlpool claims that the WHER25 reverse osmosis (RO) filtration system produces “better than bottled water” results. Relying on water well means bringing only the safest drinking water into your faucets. Whirlpool WHER25 reduces chlorine taste and odor, filters out the high occurrence of sediment, cysts, lead, chemicals, and found flowing in your unfiltered tap water.

The WHER25 filters change out in seconds. Whirlpool’s Ultraease Technology makes filter changing hassle-free because the sump pump can stay closed. No sediment-filled backwash enters the plumbing.

The WHER25’s space-saving design considers the size of the 3-stage system and offers unlimited clean water. The unit is smaller, more compact, and less expensive than competitor systems boasting 5 and 6-stage filters! Using the same activated carbon block filters and high-quality RO membrane, you’ll also use fewer filters annually, which means fewer replacement costs.

The Whirlpool WHER25 weighs just 13 pounds, and the compact filtration design measures only 4.7 x 12.2 x 13, making this the best countertop reverse osmosis system for well water.

Warranty: Limited one-year warranty on manufacturing defects

2022 Buyers Guide to the Best Reverse Osmosis System for Well Water

Purchasing the right reverse osmosis system for well water can be somewhat difficult as there are many things to be considered to ensure you make the right choice. Different systems offer unique benefits, so knowing what to look for is very important.

These are some of the most important factors that you need to take into account when you start to research such a system to help deliver clean water to your house.

3 Main Factors to Consider

  • Micron Rating: One of the most important factors that you need to consider when you decide to opt for a reverse osmosis system to help you filter well water is the micron rating of the filtration system. The micron rating refers to how well the system is able to filter incoming water and remove particles that are considered contamination in the water and potentially harmful to the well-being of you and your family. There is a total of 25,000 microns in a single inch – a lower rating means a better-quality filtration system. Overall, the micron rating means any particle bigger than that rating would not be able to pass through the system and be exposed to your body when you use the filtered water. At the moment, it is highly recommended to opt for a reverse osmosis system that has a micron rating of around 0.35 microns as this will offer proper protection against well water contaminations.
  • Water Flow Rate: Apart from the micron rating of the reverse osmosis system you are interested in buying, you also need to consider its water flow rate. This rating refers to how much water the system can filter in a certain period of time. This particular rating will be dependent on your specific requirements. The more water you rely on daily, the higher water flow rate you will need. Generally, the majority of filtration systems will offer a water flow rate that measures at a specific number of gallons per minute, which may also be abbreviated as GPM. Basic systems may only provide a water flow rate of around 5GPM, while more powerful options may offer ratings of up to 25GPM. The higher the water flow rating, the higher the price also, of course. Thus, you need to think carefully about what you need to ensure you do not spend extra money unnecessarily.
  • Value For Your Money: Finally, we also want to note the importance of considering the value that the reverse osmosis system can offer for your money. These systems are usually not cheap, especially when you consider implementing a whole-house filtration system. Thus, you need to make sure that you will be investing your money in a filtration system that will give you the best value for your money. In particular, consider all of the features provided by the system and make sure that it does not offer too many features that you will not need. At the same time, ensure you will not be buying a system that will not be able to meet the demand of you and your family.

What does an RO system do for well water with iron?

There are many issues that people are concerned about when it comes to the use of well water, especially when the water is used in their home. Hardness is by far the most common issue, and this is often combated with a water softener, but another particularly common problem that people often have to deal with is iron in well water. The filtration of well water that contains iron can be difficult. Different types of iron deposits may be present in the well water. Common types include ferrous iron, ferric iron, and bacterial iron.

This is why a reverse osmosis system is often the preferred option for well water with iron in it. RO systems usually include multi-stage filtering equipment. Different types of iron found in the water need different treatment approaches. This is why a single-phase water filtration system usually does not work. With the multi-phase filtering process offered by a top-rated RO system, the water can be filtered multiple times, and different filtering equipment is used in each of these phases or compartments – allowing for a more thorough cleaning of water and, of course, a more effective approach to removing iron contents from well water.

Final Thoughts on Buying a Reverse Osmosis System for Well Water

Before selecting the best reverse osmosis water filter for well water, you must consider a few factors. The most important is to understand the depth of your home’s water table, the depth where the water saturates the spaces between the sediment and the rock.

Deeper down between 100 and 500 feet is where most well water is “stored,” pumped to the surface, and connected to an inlet water source. As well water travels into your plumbing, so does the sediment, rust, and chemicals leached into the water from surrounding farms, city refuse sites and manufacturing.

At the inlet water source, determine the pounds per square inch (psi). You need an RO water filtration system for well water that can handle the pressure as you turn different faucets in your home on and off, run showers, flush toilets, and operate water-powered appliances. Your well water filtration system must be able to take the fluctuation of psi flowing into the house and filter the impurities simultaneously.

Finally, test your well water continually, at least every three months. Get a report of the well water in your geographical area from your local health department. After installation and between filter changes, have the water tested again and check with local agencies for updates and reports on water quality.

These critical factors will help you maintain the RO water filter systems efficiently and preserve the life of the filters.
