Water Contaminants

Tap water can contain various contaminants, including pesticides, microorganisms, organic substances, chemicals, pharmaceuticals, and harmful heavy metals like lead, mercury, and arsenic. Water pollution varies by location, so start by researching your water supply using the Environmental Working Group’s National Drinking Water Database.

Common Contaminants

Chlorine and Chloramine:

Used to disinfect water, but high levels can cause irritation and stomach upset.

Fluoride:

Beneficial for dental health in small amounts but can cause enamel staining or bone issues at high levels.

Lead:

Common due to aging pipes, can cause neurological damage and impair blood cell function.

Agricultural Chemicals:

Pesticides and herbicides from farms can seep into groundwater, causing various health issues.

Industrial Chemicals:

Runoff from industrial areas can contaminate water, leading to severe health problems.

Filter Types

Always verify that the filter system addresses the contaminants you are concerned about. Here are the main types of water filters:

Carbon Filters

Function:

Absorbs and captures carbon, chlorine, pesticides, and solvents.

Limitations:

Less effective in removing nitrates and sodium.

Area of Use:

Commonly used in faucet-mounted products.

Ultraviolet Filters

Function:

Kills bacteria, parasites, and viruses with UV rays.

Limitations:

Inefficient in filtering mineral impurities.

Installation:

Connect to an incoming water source, often combined with a reverse osmosis system.

Gravity Water Filters

Mechanism:

Use gravity to force water through activated carbon.

Additional Features:

Some have ion-exchange resins to capture heavy metals.

Mixed Filter Systems

Composition:

Combines different types of filters, such as activated carbon, reverse osmosis, and others to remove impurities.

Material

Tap water filters are usually made of plastic or stainless steel.

Plastic Filters

Advantages:

Cheap, resistant to corrosion and rust.

Disadvantages:

Less durable, need to be changed more often.

Stainless Steel Filters

Advantages:

Durable, long-lasting.

Cons:

Generally more expensive than plastic alternatives.

Flow Rate

Flow rate refers to the amount of water flowing through the filter, measured in gallons per minute (GPM).

Whole-Home Filters:

Must handle several GPM, as appliances can use up to 5 GPM.

Tap Water Filters:

Usually have a flow rate of 0.5 GPM, sufficient for filling seven or eight glasses of water per minute.

Filter Life and Use

The lifespan of a filter depends on its usage. Overuse shortens its life, requiring more frequent cartridge changes. Use the filter only for drinking or cooking to extend its life.

Filter Cartridges

When the filter loses efficiency, replace the cartridge rather than the entire system. Cartridges typically last for 100 to 1000 gallons of water or need replacement every 1-3 months.

Style and Finish

Most faucet water filters come in plastic or stainless steel designs, with various finishes available to match your home’s aesthetic.

Color Options

Plastic Filters:

Can be colored during manufacturing, usually in standard kitchen and bathroom colors.

Stainless Steel Filters:

Look elegant and can come in finishes like bronze, copper, and brushed gold.

Additional Features

Filter Size:

Consider the size of your sink and faucet when choosing a filter. Large filters may not fit smaller sinks and can look unsightly.

Filter Replacement Sensors:

Some filters have sensors indicating when a cartridge needs replacement, allowing you to plan accordingly.

Replacement Filter Cartridges:

Replacement cartridge costs vary by manufacturer. Ensure compatibility with your filter system by checking product information and the manufacturer’s website.

Installation Requirements

Faucet-mounted filters typically have quick installation processes. Follow the manufacturer’s instructions for installation and maintenance. Many filters allow switching between filtered and unfiltered water after installation.

Risks of Not Using a Tap Water Filter

Choosing not to use a tap water filter can expose you and your family to various contaminants present in your water supply, leading to health issues and poor water quality.

Exposure to Contaminants:

Unfiltered water can contain harmful heavy metals, chlorine, chloramine, pesticides, and microorganisms.

Health Risks:

Long-term exposure to contaminants can cause neurological damage, gastrointestinal illnesses, and other serious health problems.

Poor Taste and Odor:

Contaminants like chlorine can make water taste and smell unpleasant.

Environmental Impact:

Reliance on bottled water increases plastic waste and energy consumption.

Conclusion

By considering these factors, you can choose the best tap water filter to meet your needs and ensure safe, clean drinking water for your home. For further research and understanding of your water supply, visit the Environmental Working Group’s National Drinking Water Database.

FAQs

What contaminants should I be most concerned about in my tap water?

Common contaminants include chlorine, chloramine, fluoride, lead, agricultural chemicals, and industrial chemicals. Check your local water quality report to know specific concerns.

How often should I replace my tap water filter?

The replacement frequency depends on usage and the filter type. Generally, filter cartridges need to be replaced every 100 to 1000 gallons or every 1-3 months.

Are plastic filters less effective than stainless steel filters?

No, the effectiveness of the filter depends on the technology used, not the material. However, plastic filters may need to be replaced more often due to durability issues.

Do all water filters remove fluoride?

No, not all filters remove fluoride. If you need to remove fluoride, look for specific filters designed for this purpose, such as reverse osmosis systems.
