Comparison of Waterdrop 15UA and Waterdrop 17UA Under Sink Water Filter Systems

When considering an under-sink water filter system, both the Waterdrop 15UA and Waterdrop 17UA offer advanced filtration technologies to deliver clean, great-tasting water. However, there are several key differences between the two products in terms of service life, compatibility, filtration capabilities, and installation ease.

Service Life and Filter Capacity

One of the most significant differences between the Waterdrop 15UA and 17UA is their service life. The Waterdrop 15UA offers a maximum service life of 24 months or 16,000 gallons, which is ideal for smaller households or those who do not use large volumes of water. On the other hand, the Waterdrop 17UA boasts an impressive service life of 36 months or 24,000 gallons, making it a better option for larger families or commercial use.

Recommended UseSmaller householdsLarger households or commercial use

Both filters are designed to last for an extended period, which reduces the frequency of replacements, but the 17UA provides a longer filtration lifespan, making it a more cost-effective choice for those with higher water consumption.

Filtration Performance

Both systems feature multi-stage filtration that targets common water contaminants such as lead, chlorine, sediment, and various chemicals. The Waterdrop 15UA filters out lead, chlorine, heavy metals, and other impurities, while also targeting PFAS, PFOA/PFOS. The Waterdrop 17UA also effectively reduces these contaminants, but it has a slightly broader scope, targeting additional chemicals such as VOCs (chloroform, benzene, chlorobenzene, chloropicrin, and styrene) in addition to PFAS and lead. This makes the 17UA a more comprehensive solution for water filtration.

Additionally, the Waterdrop 17UA benefits from a larger filtration area, providing a 20X increase in dirt adhesion area, which enhances its filtration performance while minimizing clogging risks. While both filters are designed to reduce the risk of clogging, the 17UA’s upgraded filtration area makes it more efficient, especially in areas with dirtier or more contaminated water.

Installation and Compatibility

Both models are designed for easy installation, with push-to-connect fittings and a twist-and-lock system that allows for quick filter replacement. The Waterdrop 15UA and 17UA can be connected to standard 3/8’’ feed water valves under US sinks, but the 17UA offers an additional 3/8″ to 1/2″ converter fitting to ensure compatibility with both 1/2″ and 3/8″ cold water lines.

The installation process for both systems is quick, typically taking under 3 minutes, but it is important to note that both systems require a minimum of 21.5″ of vertical space under the sink for installation. However, users should confirm the compatibility of their faucet before purchase, as the 17UA is specifically compatible with faucets that have 1/2″ or 3/8″ female NPT threads.

Water Flow and User Experience

The Waterdrop 15UA offers a full flow rate of 0.75 GPM at 60 psi, which is adequate for household use. The Waterdrop 17UA, with the same flow rate, also provides stable and fast water supply, making it a good choice for both household and commercial settings. Customers have praised the fast flow rate and the overall performance of both filters, particularly in comparison to refrigerator filters, which they claim are much slower.

In terms of user experience, the 17UA is often appreciated for its ability to remove a broader range of contaminants and provide spring-like water taste. However, some users have noted that the filter lifespan can vary, with some experiencing failures after a shorter period, despite the product’s advertised 3-year life.

Price and Value

While both filters offer value in terms of their filtration capabilities and long service life, the 17UA’s higher initial price point is justified by its longer service life, increased filtration area, and broader range of contaminants it addresses. However, for those on a budget or with lower water consumption, the Waterdrop 15UA presents a more affordable option while still providing strong filtration performance.

However, ensure that your faucet is compatible with the system, particularly the 17UA, which is designed to connect with faucets that have a 1/2″ or 3/8″ female NPT thread.

Will these systems remove lead and chlorine from my water?

Both the Waterdrop 15UA and 17UA are designed to remove harmful contaminants, including lead, chlorine, and heavy metals. The 17UA offers additional filtration benefits, targeting a wider range of chemicals such as VOCs and other organic compounds, making it a more comprehensive solution.

Are these filters suitable for hot water use?

No, both the Waterdrop 15UA and 17UA are designed for cold water supply only. They should not be connected to a hot water line, as the filtration materials are not designed to handle hot temperatures, which could damage the system and affect its performance.

What is the water flow rate for these systems?

Both the Waterdrop 15UA and 17UA offer a flow rate of 0.75 gallons per minute (GPM) at 60 psi, providing fast and stable water supply. This makes them suitable for most household and commercial needs, with faster flow compared to many refrigerator filters.

Conclusion

Both the Waterdrop 15UA and 17UA are highly effective under-sink water filtration systems, but they cater to slightly different needs. The 15UA is perfect for those with smaller households or less water usage, offering excellent filtration performance at a more affordable price. The 17UA, with its longer service life, enhanced filtration capabilities, and ability to address a wider range of contaminants, is better suited for larger households, commercial use, or areas with more polluted water.

Ultimately, choosing between the two depends on your water usage, budget, and specific filtration needs. If you’re looking for a longer-lasting, more comprehensive filtration system and can accommodate the higher price, the Waterdrop 17UA is a solid investment. However, if you’re on a budget and need a filter for everyday household use, the Waterdrop 15UA offers great value at a lower cost.
