Its compact 6-cup capacity fits perfectly in small fridge spaces, making it ideal for individuals or small households without taking up too much room.
Installation and Maintenance
Tracking water usage and refilling is simple, enabling a steady supply of cold filtered water without the hassle of plastic bottles.
Flow Rate
The percolation speed is reasonable, balancing effective filtration with user convenience, while knockoff filters may flow faster but compromise water quality.

The Brita Metro Water Filter Pitcher is a compact and easy-to-use water filtration solution designed for everyday home use. It holds 6 cups of water, which is a modest capacity ideal for individuals or small households rather than large families. The pitcher uses a standard Brita filter that removes common impurities like chlorine taste and odor, as well as reducing metals like copper, cadmium, and mercury, which helps improve water taste and safety. The filtration flow rate is gentle but sufficient for this pitcher size, allowing you to refill without long waits. Installation is straightforward since it’s a freestanding pitcher with no complex setup, and the BPA-free plastic design is safe and lightweight. A handy SmartLight indicator reminds you when it’s time to replace the filter, making maintenance simple. Filters typically last about two months or 40 gallons, which is standard but means you will need to keep purchasing replacements regularly.

The pitcher can also work with Brita’s Elite filters for longer use and potentially fresher water, but those filters cost more and last longer. While it won’t remove all possible contaminants like some advanced filtration systems, it covers the basics well for tap water improvement. Its size and design make it convenient for small spaces, and switching to this pitcher can reduce plastic bottle waste significantly. However, if you need higher capacity, faster filtration, or removal of a wider range of contaminants, you might want to look at larger or more advanced models.

This Brita Metro model is a practical, affordable choice for better tasting and safer tap water in small quantities, offering easy maintenance and a focus on sustainability.

Buying Guide for the Best Water Filtration Systems

Choosing the right water filtration system is crucial for ensuring that you and your family have access to clean, safe drinking water. The right system can remove contaminants, improve taste, and provide peace of mind. To make an informed decision, it's important to understand the key specifications and how they relate to your specific needs. Here are the main factors to consider when selecting a water filtration system.
Type of Filtration SystemThere are several types of water filtration systems, including activated carbon filters, reverse osmosis systems, UV filters, and distillation systems. Each type has its own strengths and is effective against different contaminants. Activated carbon filters are great for removing chlorine and improving taste, while reverse osmosis systems are effective against a wide range of contaminants, including heavy metals and nitrates. UV filters are excellent for killing bacteria and viruses, and distillation systems remove most contaminants by boiling and condensing water. Choose a system based on the specific contaminants you need to remove and your water quality.
Filtration CapacityFiltration capacity refers to the amount of water a system can filter before the filter needs to be replaced. This is usually measured in gallons. Systems with higher capacities are more convenient for larger households or for those who use a lot of filtered water. For small households or occasional use, a lower capacity system may be sufficient. Consider your daily water consumption and choose a system that can handle your needs without frequent filter changes.
Flow RateFlow rate is the speed at which water is filtered and dispensed, typically measured in gallons per minute (GPM). A higher flow rate means water is filtered more quickly, which is important for larger households or for use in situations where you need a lot of water quickly, such as cooking or filling a bathtub. For drinking water or small household use, a lower flow rate may be adequate. Assess your water usage patterns to determine the appropriate flow rate for your needs.
Contaminant RemovalDifferent filtration systems are designed to remove different types of contaminants, such as chlorine, lead, bacteria, viruses, and other harmful substances. It's important to know what contaminants are present in your water supply, which you can find out through a water quality report or testing kit. Once you know what needs to be removed, choose a filtration system that is certified to remove those specific contaminants. Look for certifications from organizations like NSF International to ensure the system meets industry standards.
Installation and MaintenanceSome water filtration systems are easy to install and maintain, while others may require professional installation and more frequent maintenance. Under-sink and countertop systems are generally easier to install and maintain, while whole-house systems may require more complex installation. Consider your DIY skills and willingness to perform regular maintenance when choosing a system. If you prefer a hands-off approach, look for systems with longer-lasting filters and minimal maintenance requirements.
Cost of Replacement FiltersThe cost of replacement filters can add up over time, so it's important to consider this ongoing expense when choosing a water filtration system. Some systems have more affordable filters, while others may have higher costs due to the complexity of the filtration process. Check the frequency of filter replacement and the cost of each filter to estimate the long-term cost of maintaining the system. Choose a system with replacement filters that fit within your budget and are readily available.
Size and DesignThe size and design of the water filtration system can impact where it can be installed and how it fits into your home. Countertop and pitcher filters are compact and portable, making them ideal for small spaces or renters. Under-sink and whole-house systems are larger and require more permanent installation. Consider the available space in your home and choose a system that fits comfortably without disrupting your living area. Additionally, some systems come in sleek designs that can complement your kitchen decor.
