Home Test Kit Guide
Home testing kits are becoming more common. Many brands provide reliable instruments at affordable prices. In case you cannot afford a fully independent laboratory test, or you cannot find one in your area, you can look for the best home testing kits on the market.
Choose the Proper Kit
Here are some factors to consider before buying a home water test kit:
- Your water pH influences quality, so you can start with such a test. Acidic water has a foul taste and contributes to pipes’ corrosion.
- A pH testing kit may help you make the best choices when it comes to buying an ionizer machine, for instance.
- Hard water leads to scale buildups. This can lead to shorter lifespans in your appliances.
- Well water and city water are different. Make sure you buy a testing kit that addresses them separately.
- Some testing kits are efficient in finding heavy metals. Others are more capable of testing for waterborne pathogens. Make sure you are purchasing the right one for your needs.
Most testing kits come with test strips. We suggest testing kits with many different types of test strips. This allows you a broad range of separate tests for chlorine, hardness, bacteria, lead, other heavy metals, fertilizers, etc. A test kit containing only one strip is most likely just a pH test.
Using a Test Kit
Read the instructions carefully. A reliable test kit coming from a reputable manufacturer comes with detailed directions on how to sample the water and use the test strips. You will also learn what temperature the water should have, how long you can wait for the results, and how to interpret them.
Can You Test Your Water at Home?
You can buy a water testing kit from online retailers, your local home center, or a home depot store. Most water testing kits feature color-coded strips. You can also find vials or digital pens. The strips contain reactants that change the color depending on the contaminants in your water, indicating the presence and levels of contaminants.
Are the Home Water Test Kits Accurate?
Professional manufacturers design water testing kits for various water sources: well water, city tap water, hydroponics, etc. We recommend you get those kits coming with certification to match the EPA standards. There are more types of tests and some are more accurate than others.
What Is the Best Home Water Test Kit?
Depending on your water source, we recommend the Varify Complete Water Test Kit for tap water, the Health Metrics Well Water Testing kit for well water, and the AquaVial Test Kit for coliform bacteria.
Today, it’s not uncommon for drinking water to be contaminated with any number of impurities. Heavy metals, bacteria, viruses, and fertilizer can all make an appearance in drinking water.
Testing the quality of your water can be a matter of using your senses, requesting an official report, or using at-home test kits. Regardless of which method you use, identifying the contaminants in your water is the first step to taking control of your water quality at home.
Armed with all these results, you can compare them and draw conclusions. Once you narrow down your research, you can identify your top contaminants. Then you can pick a filter to specifically target those contaminants.
The only way to know exactly what you’re drinking is by testing your water with a good, reliable testing kit. The water test kits in the list above are all affordable and reliable. Many of them test against EPA standards. Before you go on and buy a water filter, you should first understand what you need water filtration for – is it hard water, heavy metals, or bacteria?
It doesn’t cost much to make sure the water in your home is the best quality for you and your family.
