Well Water Filtration System Review

1. Analyze Well Water Quality

⇑ Back to table of contents

Test Kit Well for Water Filtration SystemThe presence of bacteria is possible contamination from animal or human wastes. Some come from vegetation, soils, insects, etc, other come from fecal matter. Common sources of nitrate are septic systems, fertilizers, leaking sewer lines and animal manure.NGWA (National Ground Water Association) recommends testing well water for nitrates, bacteria, and any local concern contaminants. Well water testing should be considered additionally if there is a change in the water odor, taste, or appearance, family members have recurrent incidents of gastrointestinal illness. You should check with your local department for recommendations and interpreting your water tests.

Typical additional tests are those for hardness, pH, manganese, iron, sulfides, etc., that cause problems with staining, plumbing, water odor and appearance. Your state may require testing for specific to locality contaminants. On rare occasions in water occur radon and arsenic. Arsenic comes into the water in result of contact with some soils. Radon comes from the natural breakdown of uranium in the ground. It is an odorless, tasteless and colorless gas.

Quick and cheap way to check your water is using well-water test kits. They are specifically designed to easily check for the copper, iron, bacteria, lead, nitrates, pesticides, chlorine, pH, nitrites, hardness, and other contaminants found most commonly in well water. They are accurate and give you lab-quality results. Labs charge about $200 for the set of tests, similar to $20 test kit. And if you want to be absolutely precise, you can pay the local lab to test the water for the particular contaminant, looking weird in your test kit results.

2. Well Water Preliminary Treating

In accordance with the results of testing, it may be advisable to use additionally preliminary water treatment units (if they are not in the structure of the filtration system)

2.1 Preliminary Well Water Filtration

iSpring WSP-50 - Reusable Spin Down Sediment Water Filter - 50 Micron, 20 GPM, 1" MNPT + 3/4" FNPT

Well water contains sediment, insoluble particles, and dirt. For sediment reduction purposes there are available wound, spun or pleated polypropylene filters available with a variety of micron numbers. For the preliminary water filtration are good 10-50 micron filters.

Sediment filters are cheap, easy to install and eliminate lots of sand, dirt, silt, algae, rust particles, etc before they reach the rest of your plumbing system, including expensive appliances.

They don’t remove chemicals and heavy metals but protect and prolong working time of advance water treating systems. You may use any filter made of wound string, polypropylene, ceramic, polyester, cellulose, etc.

Rough sediment filters are an ideal first layer of filtration before a comprehensive filtration system. They are cheap, cartridges often are reusable and flushable, take off considerable workload from expensive fine filters that follow it.

2.2 Well Water Softening

Hard drinking water but can pose some problems in water heaters, plumbings and other equipment, forms limescale in kettles, cause some health problems. Уou can determine by your test results whether your water is hard using the following table.


hardness in ppm hardness in gpg hardness in dGH/°dH hardness in mmol/L hardness in mg/L
Very hard

> 181

≥ 10.57 ≥ 10.12 ≥ 1.81

≥ 181



7.06-10.51 6.75–10.11 1.21–1.80


Moderately hard


3.56-7.01 3.38-6.74 0.61–1.20



less than 60

0-3.50 0-3.37 0–0.60

Water softeners remove calcium, magnesium, etc. from hard water (but softeners don’t provide any other water treatment like contaminants removal and filtration).

The resulting soft water extends the plumbing lifetime, more compatible with soap and has some health benefits.
Softeners with Ion-exchange media use an ion-exchange resin in which Ca2+ and Mg2+ ions are exchanged for sodium/potassium ions (Na+ or K+). There are also Ion exchange resins for removing sulfate, bicarbonate, and carbonate ions.

2.3 Ultraviolet Sterilizing Units

Ultraviolet Water Purifier For Well Water Filtration System
Ultraviolet Whole House Sterilizer, 12 GPM

A UV water purification devices destroy effectively most of the waterborne microorganisms. They are chemical free and environmentally friendly, have no disinfection byproducts.

Whole house Ultraviolet Sterilizers consumes less than 100W (55W for 12 GPM system) and kill with an ultraviolet lamp Viruses Fungi, Algae & Microbes, harmful Bacteria, E-Coli, etc.
You’ll have a complete system with a UV bulb in a glass tube, mounting clamps, etc. Typical UV bulb change time is 1 year.

UV systems are easy to use, need quick annual service, reliable, consistently keeping water safe without chemicals. They don’t need holding tank, water just flows through the system. UV units are low energy usage and are Food & Drug Administration approved, approved for disinfection by FDA.

Ultraviolet water sterilizers work effectively if water is clear. If the water contains “floaties”, or is murky, ultraviolet light cannot effectively reach microorganisms. You need to use preliminary filtration (10-micron filter is enough).

3. Choosing the Best Well Water Filtration System

⇑ Back to table of contents

Well water filtration system must soften the water if it is hard, eliminate sediment particles, improve the taste, clean it from iron, heavy metals, improve the odor.

Activated carbon filter and filters with metals removal resin works well for lead and other heavy metal reduction. Arsenic and nitrate reduction filters use activated alumina cartridges. The 3-stage carbon systems are an effective solution for well water supplies and can provide clean water for a large home.

In some cases using reverse osmosis system is necessary. RO systems do remove most potentially hazardous contaminants from water. RO systems remove salts, heavy metals, and other mineral things like silicates, copper, etc.

Aquasana Rhino 6-Stage 500,000 Gal. Well Water Filtration System with Simply Soft Salt-Free Water Softener and UV Filter

A good example of a ready-to-use and all-inclusive unit is Aquasana Rhino 6-Stage well water filtration system with UV Filter and salt-free Softener.

The system is designed specifically for common well water contamination and protects from viruses, bacteria, and other.
Well water filtration system includes large 20 in. preliminary filter, sub-micron fine filter, and Aquasana ultraviolet sterilizer. The system reduces body’s exposure to harsh synthetic chemicals that can cause excessive drying and damage.

SimplySoft softener chemically removes minerals and does not put excess chemicals and salt waste into our environment. SimplySoft does not require electricity, complicated salt replacement or drainage for wastewater.

UV filtration kills viruses and bacteria including cryptosporidium and giardia. Aquasana Rhino 6-Stage
system has the included preliminary filter but if you install additional sediment filter before the system, then you’ll change fine filters less frequently.

The installation is pretty easy and straightforward, the system looks great. Comes with all you need short of a wrench. There is an about 10psi pressure drop, you can compensate it with the pressure regulator.

You’ll feel a noticeable difference in water quality, from drinking to washing and showering. Even if you have brown well water, it will become perfectly clear and you will save a lot of money on bottled water.
