Of course, for good health practices, you can also test the filtered water of a filtered water pitcher

Best Home Water Test Kit: FAQs

Before we finish this guide, let’s answer some pressing questions regarding drinking water contamination, the efficiency of the best water test kit you can find, and a few more issues related to water testing!

Is a home water test kit reliable?

You have four main ways to learn about the contaminants in your drinking water and we recommend you use all three of them in conjunction:

  • Use your senses. If your drinking water has an unpleasant smell or taste, if you see particles depositing on the bottom of the glass or floating in the glass, you should take things a step further.
  • Ask for a water quality report for your area. As a rule, you should receive an annual report regarding the water contaminants in the area you live in from your local authorities. If they do not send it to you, ask for one to have a general idea of what you must deal with in the future. Upon reading the report, take note of all contaminants that may need further water testing. For instance, if you have lead in water, get the best well water test kit or another water test for lead.
  • Use a water testing kit as instructed. Our recommendation is to repeat the test – in case you have spare strips – to eliminate any human or technical error. You can trust water testing kits coming from reputable manufacturers. To answer the question, yes, most are reliable if you use them correctly.
  • The fourth method – and the most expensive one – is to send a water sample to an independent water testing laboratory. If you do so, make sure you request testing for the most prevalent contaminants you discovered in your water after you cross-referenced the water quality report with the water testing kit’s results.

Does boiling water remove lead?

Since the Flint water crisis, lead in water became a national problem and concern. Unfortunately, you cannot rely on boiling your water. In fact, boiling does not remove chlorine in water, lead, iron, or other heavy metals and contaminants. Moreover, hot water may actually dissolve more lead than cold water, so do not cook or drink water that comes through the hot water tap. 

One of the best methods to remove lead in water you drink is to consider an under-sink reverse osmosis water filter. If you do not want to come in contact with any particle of lead when you use water for bathing, cooking, cleaning, and so on, we recommend you to consider a whole house water filter with activated carbon technology.

What are the most common drinking water contaminants?

When we discussed the water quality in the U.S., we mentioned chlorine, waterborne pathogens, nitrate, arsenic, lead, fluoride, mercury, copper, and other water toxins and contaminants. While water testing and water treatments improved in the past years, we still ingest and use a high number of chemicals, radiological elements, heavy metals, pesticides, antibiotics, and more. Even if you live in a state/area with relatively clean water, you should still get a water test kit to make sure. If you are among the approximately 43 million Americans relying on private wells for their drinking water, you should get the best well water test kit right now!

Can your drinking tap water kill you?

Yes. If the Flint water crisis taught us anything, it was that sometimes, our drinking water can kill us. Lead in water and water laced with other contaminants like bacteria and protozoa can lead to the onset of severe illnesses and even death. Brain damage, liver and kidney problems, red blood cells’ disruptions, and more correlate with drinking water with lead and other heavy metals.

What are the symptoms of drinking contaminated water?

Some of the most obvious symptoms of drinking contaminated water are gastrointestinal problems, nausea, vomiting, diarrhea, stomach/intestinal pains, dehydration, and more. If you experience any of these symptoms, see a doctor immediately. Afterward, test your water and invest in the best water filter for your needs!

Should I filter the tap water I drink?

Yes, you should. However, we recommend you do your homework first. Water testing is the first step in learning what water contaminants you should remove from your drinking water. Next, learn how water filters work. Armed with these results and information, pick the best water filters for your needs. Make the difference between carbon-based water filters, reverse osmosis filtration, water distillers, and so on.

What water filters should I buy to remove water contaminants?

Here is an updated table showing you what type of filtration technology you need and what types of water filters to consider depending on the water quality of your home and the contaminants present in your drinking water!

Situation Solution
Contaminated city/well water (big house/family) Whole house water filters with adsorption (activated carbon filters)/reverse osmosis
Contaminated city/well water (medium/small house or family) Under sink water filter with reverse osmosis/countertop water filters with activated carbon filtration/water distillers
Hard water/stains on dishes/dry skin/funny water smell A water softener/water descalers
Really bad taste and odor on tap water Faucet water filters with activated carbon or under-sink RO water filters
Medium bad taste and odor on tap water Water filter pitchers with activated carbon filtration
Bacteria/viruses/microorganisms in the water RO whole house water filters/under sink RO water filters & mandatory additional UV filter
RV travel and living On the go whole house water filters for RVs/water filter pitchers
Moving around, renting, changing location often Faucet water filters with activated carbon technology or water filter pitchers
Contaminated water outdoors/hiking/survival & preparedness
Water filter bottles

Bottom Line

Water test kits are helpful and reliable for you to get actionable results without having to send mails to private laboratories, wait weeks for results, and spend a lot of money. You can go for general screeners, covering a wide range of water problems and contaminants, or for specific issues that are concerning for you (heavy metals, bacteria, TDS, etc.). Water testing kits allow you to choose the best filtration system for your needs but also check out its efficiency.
