How To Tell If You Need A Filter System For Drinking Water

Water filtration is a method to improve your water quality. People have been filtering water for thousands of years. There is evidence that basic sediment filter systems (which used sand or gravel) date back to 2000 B.C. Hippocrates, Archimedes, and other great minds were also involved in water treatment. They pioneered a variety of filtration methods that are still used today, although in different forms.

Water filters have made great strides since 2000 B.C. We’re going to take a deep dive on water filtration and give you all the information that you need to determine if your water is suitable for a whole-home or sink water filter.

Water Filtration: What, Why, and How

Water filtration has an interesting and long history. However, the goal remains the same: Safe, clean drinking water without harmful contaminants, bacteria or other irritants such as a chlorine taste and a marshy smell. As societies evolved, there were other reasons for protecting our water supply, such as avoiding hard water spots or filling tanks for our aquatic pets. Water filtration, regardless of its objective, is about improving water quality.

This is the “what” or “why”, but the “how” is what makes things truly exciting.

Water filters can have different methods of improving tap water quality, despite sharing the same goal. A whole-house water filter system treats specific water quality issues in your home. It is responsible for improving tap water quality for cleaning, drinking, and bathing. To improve the quality of your drinking water, you can install under-sink filters at one tap. These can cause problems with taste or odor, or concern about contaminants such as lead or mercury. Many people use reverse Osmosis for this purpose. *

Water filtration does not remove hardness from water. This is a separate process called Water Softening. It’s distinct from reverse osmosis or other water filtration methods. Reverse osmosis uses water to force water against a semipermeable membrane that filters a wide range of contaminants. A water softener uses a magnet-like reaction to attract and trap hardness-causing minerals. Water softening and water filtering are not mutually exclusive. You can have both systems installed to improve your control over your home’s water supply.

Is a water filter necessary for everyone?

Many factors can affect water quality. These variables can include:

  • Local geography
  • Pollutants nearby
  • Guidelines for water quality in the United States
  • Home plumbing
  • Weather patterns
  • Temperature

Water quality can vary due to many factors. Even if you haven’t had any problems with your water supply for many years, new issues can suddenly surface in your sink water. Even if your neighbor does a water test and finds no major issues, it is possible that your water supply may still be having problems.

This is especially true of well water users. Well, owners may not have identical water quality due to differences in the water transport infrastructure and structures of wells. Private wells are not covered by the same safety and health guidelines as municipal water supplies. well, water users need to have regular water tests. Although the general recommendation is to test your well once per year, you should also test for any new issues (such as sudden odors or extreme environmental events (such as droughts).

Well, water users have unique challenges, but city water users can benefit from water filtration systems. These protective measures, such as adding chlorine to your tap water for sanitation, are in accordance with North American and local guidelines. However, they can cause aesthetic problems that could make it unpalatable to drink or use to cook. There are also potential problems once the water leaves a municipal treatment center. Your water could absorb contaminants along its journey to your home. It is a good idea to have your water tested annually by city water users.

Pure water is rare even in nature. This means that no matter where water is sourced, it’s possible to find more than water in your tap.

Signs that you need a water filter system

Water filtration can be beneficial for almost everyone. There are signs that water filtration is needed. Let’s take a closer inspection:

Water Test Results

Your yearly water test is the best way to find out if you need a water filter. Water tests, when done by an expert can provide key information about the water quality and whether there are any contaminants. These results can help you find the right water filter system or solution.

Known Water Issues

If there are serious water problems in your area, this is another sign that you need to filter water. These could include water quality issues, accidental contamination of the water supply or problems with your local well. Flint, Michigan, for example, is well-known for its past water quality problems. This can encourage residents to look into water filtration, even if they have already addressed the problem.


You’re likely to expect pure-tasting tap water when you reach for it. It can be distressing to taste the water that tastes like a swimming pool, penny, or swamp. Unusual flavors can be caused by water problems, such as chlorine, copper, and decaying organic material.

Some water taste problems are only cosmetic, meaning they aren’t dangerous for your health. Others can be more harmful to your family and home. Any change in water taste should be a reason to get a water test.


You may have experienced sink water that smells like rotten eggs. While this particular problem is usually caused by hydrogen sulfide there are many other odors that can be more difficult to spot. You might also have difficulty determining if the smell is coming from water or the pipes, or any other nearby elements.

It is a good idea to get a water test done whenever you notice an unusual odor. Even if your plumbing is the problem, it’s possible that your water supply has the problem. For example, a low pH level could cause copper pipes to corrode, which can lead to further water quality problems.


You might think of water as being perfectly clear, but the truth is that even pure water has a light blue tint. This is a sign that you might need a water filtration system.


Tap water can sometimes leave stains on your laundry, sinks, and bathtubs. These stains, although not very noticeable, aren’t necessarily a sign that you have a health problem. However, they can make household chores more expensive and time-consuming. A home water filter is a great option if you don’t want time or money spent cleaning up water stains.
