The Whole House Water Filter System by EXPRESS WATER is a robust solution for providing clean and safe water throughout your home. It utilizes a 3-stage filtration process that includes top-tier granular activated carbon (GAC) and activated carbon block (ACB) filters, which are effective in significantly reducing chlorine, sulfur odor, and other contaminants. This system is suitable for various water sources including well, tap, and municipal water.

The durable stainless-steel frame and 1-inch standard connections support a maximum flow rate of 17 gallons per minute, ensuring consistent water pressure for household needs. Additionally, the system is designed for easy installation with quick-change cartridges and comprehensive support fittings, making maintenance straightforward. Each filter has a lifespan of about 6 months, providing up to 100,000 gallons of purified water before requiring replacement. This extended capacity means less frequent maintenance, which is advantageous for busy households. However, it is a freestanding unit with dimensions of 23”L x 8”W x 29”H and a weight of 62 pounds, which may require ample space for installation.

The system is heavy-duty and reliable, requiring no batteries and operating within a pressure range of 20-80 PSI. It does come with a higher upfront cost and may be more suitable for larger homes or families looking for substantial water treatment. The system’s ability to improve water quality significantly can also positively impact skin and hair health and prolong the life of household plumbing and appliances. This water filter system is ideal for those seeking a comprehensive and durable solution for household water filtration.

Buying Guide for the Best Small Water Filters

Choosing the right small water filter can significantly improve the quality of the water you drink, cook with, and use daily. It's important to understand the key specifications and features to ensure you select a filter that meets your needs. Here are some essential aspects to consider when picking a small water filter.
Filter TypeThe filter type determines what contaminants the filter can remove from the water. Common types include activated carbon filters, reverse osmosis filters, and UV filters. Activated carbon filters are great for removing chlorine, bad tastes, and odors. Reverse osmosis filters can remove a wider range of contaminants, including heavy metals and dissolved solids. UV filters are effective against bacteria and viruses. Choose a filter type based on the specific contaminants you want to remove from your water.
Filter CapacityFilter capacity refers to the amount of water a filter can process before it needs to be replaced. This is usually measured in gallons or liters. Smaller capacities (up to 100 gallons) are suitable for personal use or small households, while larger capacities (over 100 gallons) are better for families or frequent use. Consider your water consumption and how often you are willing to replace the filter when choosing the right capacity.
Flow RateFlow rate indicates how quickly the filter can process water, usually measured in gallons per minute (GPM). A higher flow rate means water is filtered faster, which is convenient for busy households. For personal use or small households, a flow rate of 0.5 to 1 GPM is typically sufficient. For larger households or higher water usage, look for a flow rate of 1 GPM or higher. Choose a flow rate that matches your daily water usage needs.
Filter LifespanFilter lifespan is the duration a filter can effectively work before it needs replacement, often measured in months. Shorter lifespans (up to 3 months) may require more frequent replacements, while longer lifespans (6 months or more) offer convenience and cost savings over time. Consider how often you are willing to replace the filter and the associated costs when selecting a filter with the appropriate lifespan.
Installation and MaintenanceSome water filters are easy to install and maintain, while others may require professional installation or more frequent maintenance. Simple pitcher filters or faucet-mounted filters are easy to install and maintain, making them ideal for renters or those who prefer a hassle-free option. Under-sink or whole-house filters may require more effort to install and maintain but offer more comprehensive filtration. Choose a filter that matches your comfort level with installation and maintenance.
CertificationsCertifications from organizations like NSF International or the Water Quality Association indicate that a filter has been tested and meets specific standards for contaminant removal. Look for filters with certifications to ensure they effectively remove the contaminants they claim to. This is especially important if you have specific health concerns or want to ensure the highest water quality. Choose a certified filter to have confidence in its performance.
