Water Filters: Understanding Your Options and Making an Informed Decision
As Dan Toole, Consumer Reports' water filter expert, explains, "water filters are not the most glamorous product, but they can give you better-tasting water and maybe even protect your family from harmful contaminants." With so many options available, it's essential to understand what types of water filters exist, their pros and cons, and how to choose the right one for your needs.
Who Needs a Water Filter?
If your water is discolored, has an odor, or contains known contaminants, you need a filter. According to Dan, "the first step in choosing a water filter is to determine if you need one." If you're unsure about the quality of your tap water, you can have it analyzed at least once a year. You can also check your monthly water bill and review your company's Consumer Confidence Report (CCR) for information on basic contaminants found in your water. Additionally, visiting the EPA's website and taking a sample of your water to a state-certified lab will provide you with accurate information on what contaminants are present in your water.
Testing Water Filters in the Lab
In the Consumer Reports' lab, Dan and Chris Regan use a large rig to connect various filters and test their effectiveness. The process involves flowing water spiked with lead and other contaminants through each filter, taking samples, and analyzing them to determine how well they remove those contaminants. This rigorous testing allows for a comprehensive understanding of each filter's performance.
Five Basic Options for Water Filters
There are several types of water filters available, each with its pros and cons. Let's explore the five basic options starting with a pitcher or carafe:
* Pitcher or Carafe: These filters are easy to use, inexpensive, but limited in their capacity. They can only produce about two or three gallons of water per day.
* Faucet-Mounted Filter: This type connects directly to your faucet and allows for on-the-fly filtration. However, it may not adapt to every faucet, and its effectiveness is dependent on the flow rate of your faucet.
When choosing a faucet-mounted filter, consider the volume you'll need. If your household consumes a lot of filtered water daily, upgrading to a countertop model might be necessary. While countertop models are easy to install and allow for significant contaminant removal, they may not fit every faucet, and clutter can still be an issue if you don't have enough counter space.
For households with limited counter space, under-sink filters offer a solution. These models filter large volumes of water while keeping installation out of sight. However, installations are slightly more involved, and professional assistance might be necessary.
Advanced Water Filters: Reverse Osmosis Systems
If you need a more comprehensive filtration system, consider reverse osmosis (RO) systems. These systems involve a large storage tank, tubing, filters, and even faucet installations. While they provide excellent contaminant removal, they are more involved and require professional installation and maintenance.
Key Considerations for Choosing the Right Water Filter
When selecting a water filter, there are several factors to consider:
* Filter Life: Many models have limited capacities, so it's essential to factor in replacement costs.
* Maintenance: Some filters may require more frequent cleaning or replacement than others.
* Contaminant Removal: Consider what contaminants you want the filter to remove from your water.
In conclusion, choosing the right water filter for your needs requires careful consideration of various factors. By understanding the different types of filters available, their pros and cons, and how to choose the right one, you can make an informed decision that will provide you with clean, safe drinking water.
