Actions To Do Before Buying The Best Filter For Well Water

Before investing in a filtration system for your well water, it’s beneficial to conduct a test of the liquid to determine what pollutants are in it and how much of them are present. This will help you decide if contaminants are adequate to necessitate filtration.

It is possible to acquire water testing sets online and conduct them in the comfort of one’s home. Some of these must be sent to a laboratory for evaluation, whereas others are for household usage. These domestic test kits include strips that shift color based on the present pollutants.

It is possible to employ a water service provider in the nearby area to conduct tests on the water. The Centers for Disease Control & Prevention suggest people analyze their well water yearly.

Things To Consider When Choosing The Best Filter For Well Water

When selecting a well water filtration system, it is essential to examine some components, such as the kind of pollutants it will eliminate, the size of the filter, the flow rate, as well as the type of filter. Assessing these details will help to decide on the best filter for well water for a residence.

Filter Type

Whole-house filtration systems use different water filters for well water. These include activated carbon, resin, reverse osmosis, water ionizer, UV, and infrared filters.

  • Water ionizer – Water ionizers employ an electric current to purify water and can eradicate heavy metals and pesticides. Check what pollutants a particular brand can eliminate to ensure it’s the correct decision for the water.
  • Infrared filters – These filters utilize light and heat to make hard water softer, which benefits households with hard water. While it can eliminate bacteria, it is not the best choice for removing other impurities.
  • Activated carbon – Carbon filters can trap pollutants, blocking them from moving through the filter. Activated carbon fiber filters from coconut shells are especially effective at reducing pesticides and lead, but they can also take out iron and bacteria.
  • Reverse osmosis – Reverse osmosis works by applying pressure to a semipermeable membrane, which blocks the passage of heavy metals and fluoride. However, it is not efficient for eliminating pesticides and other organic pollutants.
  • UV filters – A UV lamp is the most reliable way to eliminate bacteria but it cannot stop other pollutants in drinking water.

Certain systems make it possible to deploy several filters to block out impurities. For instance, UV filtering can eliminate bacteria from the water. If contaminants like organic chemicals or lead are present, an activated carbon filter should be added.

Filters can be employed in several steps to remove pollutants from water that are safe for drinking. For instance, the first stage could take out sediment, and the fourth phase could eliminate organic substances. Numerous setups can include a UV light source to destroy microorganisms.

Flow Rate

When discussing a water filtration system, it is essential to consider the flow rate, which is the quantity of water that can be filtered and prepared for use at any given moment. This rate is normally specified in gallons per minute (GPM).

Different whole-house filtration systems may have different flow rates, with some ranging from 7 to 15 or 20 gallons per minute. When selecting the most suitable well water filtration system, it is essential to consider the amount of water flows a home requires.

You can determine the water rate running through home pipes by collecting the water from a specific faucet and measuring it. To do this, capture the full-force water from the faucet for 10 seconds in a container and then multiply the number of gallons you have collected by six to work out the gallons per minute from that fixture.

The GPM (gallons per minute) rate of water flow for a residence is typically between 6 and 12, according to the size of the house and the number of occupants. Nevertheless, it can also depend on an individual’s preference, based on the speed at which they wish the filtered water to be available.

NSF Certification

If a water filtration product has the National Sanitation Foundation (NSF) certification, it guarantees that it functions as the manufacturer has advertised.

Suppose a water filtration system certified by the National Science Foundation (NSF) claims to reduce iron levels to three parts per million (ppm). 

Not all filtration systems have NSF certification. The items that are NSF-certified are produced with components that do not add additional pollutants to the water, for instance, plastics that contain bisphenol A (BPA). This man-made chemical links to endocrine disruption in humans.

Water Contaminants

Various filtration techniques help get rid of pollutants in drinking water. Some remove heavy metals, while others are more effective in eradicating bacteria. Before you purchase a water filtration system for your residence, it is essential to identify what pollutants are present.

Here are the common contaminants in well water: 

  • Nitrate – Nitrate content in groundwater is usually harmless, but if there are high levels, it can create problems. Excessive nitrate intake can lead to headaches, nausea, and a heightened risk of cancer.
  • Organic chemicals – A variety of toxic materials, for example, pesticides, drugs, paints, colors, and sanitizers, can pollute groundwater. These organic chemicals can damage the liver, kidneys, and nervous and reproductive systems.
  • Iron – Iron pipes used in plumbing systems can cause water to become contaminated as it enters the home. It is also possible for iron to be present in the water due to its natural occurrence in the soil. Generally, low amounts of iron will not have an adverse effect. However, high concentrations can cause concern, leading to organ damage, acne, exhaustion, and joint aches.
  • Sulfur – Excessive sulfur in drinking water is not necessarily hazardous, yet many people find the smell of sulfur unpleasant and reminiscent of rotten eggs.
  • Microorganisms – Many houses have well water containing coliform bacteria and E. Coli, which can be harmless in small amounts. However, there are large amounts of bacteria present. In that case, it may result in illnesses and even death, so take safety measures like filtration to reduce the bacteria levels.
  • Heavy metals – Metals like copper, lead, cadmium, arsenic, and chromium can be present. Although small amounts of these elements generally don’t create a problem, a significant build-up of heavy metals can lead to health issues, including a heightened chance of developing cancer if ingested over a long period.
  • Fluoride – Fluoride is regularly put into public water sources to help battle cavities. However, it can also taint private wells, and excessive fluoride in the body can be damaging, causing sickness, vomiting, convulsions, and fluorosis of the bones.
  • Sediment – Naturally, the filter should eliminate small particles like sand & soil in groundwater to ensure the water is sanitary and reduce damage to machines.

Filter Size

The size of water filtration systems can vary, which will influence the placement of the device in residence (e.g., under a kitchen sink) and the amount of water it can process in one go.

The height of some water purification systems exceeds 50 inches, and some measure less than 30 inches. The filter size also affects how many gallons of water the system can clean before it must be replaced. Certain brands have a designated time limit for when the filter needs to be switched out.

Generally speaking, it is necessary to replace water filters regularly. Some require a replacement every 3 months, while others may only need to be swapped out every 9 months or yearly.

The effectiveness of a filter is contingent upon the kind of filter, the amount of water it can process, and the number of unwanted substances that need removal.

Built-In Water Softener

Certain home water purification systems come with an integrated water softener feature. This type of system is suitable for residences with hard water with a high concentration of minerals, like calcium and magnesium, that can cause damage to plumbing and appliances if left unchecked.

Filtration units can use either a salt-driven or salt-free system to make the water gently. Home water filtration systems with built-in water softeners often use salt-free water treatment techniques. These systems do not eliminate the minerals from the water but soften it to stop mineral accumulation.


Certain filtration systems designed to service an entire house are simpler to install than other systems. In some cases, users can install them on their own, while hiring a professional is necessary for different situations. Some filtration systems also come with a kit to help simplify the installation process.

If you lack knowledge in plumbing, other systems will advise you to hire an expert to install the filtration system.

The comfort of setting up a well water filtration system is certainly something to take into account, but it is not necessarily the only thing to consider. What matters more is that the filtration system can effectively remove the pollutants present in the water.
