Understanding the Limitations of Water FiltersWhen it comes to water filtration systems, many people assume that they can automatically remove all contaminants from their drinking water. However, it’s important to understand that even the best water filters have their limitations. No treatment or filter can be 100% effective in getting rid of all contaminants in your water. It’s vital to take note of the specific contaminants that you’re dealing with and the type of filter needed to address them. Additionally, water filters have a limited lifespan. Once the filter reaches its capacity, it won’t be effective anymore. Therefore, regular replacement of the filter is important, depending on the manufacturer’s instructions. It’s essential to know the filter replacement schedule and to stick to it to ensure that the filter continues to work effectively.
Identifying Your Water Filter GoalsBefore buying a water filter, it’s crucial to identify your specific goals for the filtration system. Are you simply seeking to make your tap water taste better? Do you have a more critical problem like lead or bacteria contamination? Knowing your objectives in advance will help you choose the filter that meets your needs. It’s essential to consider the following:
- Contaminants you are seeking to remove
- The filtration rate and lifespan needed
- Your budget
Investigating Water ContaminantsWater contaminants exist in different forms. They can occur naturally or due to human activities such as pollution. Identifying the contaminants in your water is the first step to solving the problem. You can test the water in your home using kits you can purchase online or through Environmental Protection Agency services.
- Microbes such as bacteria, viruses, and protozoa
- Heavy metals such as lead and mercury
- Chemicals such as chlorine, herbicides, and pesticides
- Fluoride, a naturally occurring mineral found in groundwater
Understanding Filter TechnologiesWater filters use different technologies to purify water. Some of the common types are carbon filters, reverse-osmosis filters, and activated alumina filters. It’s important to note that each filter technology has its strengths in removing specific contaminants. Understanding the filter technologies will enable you to choose the most suitable filter for your water treatment needs. Below are some of the filter technologies and what they remove:
- Carbon filters: Removes chlorine, pesticides, and herbicides, it also enhances taste and odor of drinking water
- Reverse-osmosis filters: Removes bacteria, viruses, heavy metals such as lead and mercury, and other contaminants from water
- Activated alumina filters: Removes fluoride, arsenic, and other heavy metals from water
