Who Should Buy This

This PUREPLUS Under Sink Water Filter System is perfect for anyone who wants clean and safe drinking water at home. It is great for families, especially those who are concerned about chlorine and heavy metals in their tap water. If you want a simple and effective way to improve your water quality without buying bottled water, this filter is a smart choice. It is also ideal for people who prefer a direct connect system that fits neatly under the sink and saves space.

However, if you live in a place where your water does not have chlorine or heavy metals, or if you need a filter for very large volumes of water beyond 22,000 gallons, this product might not be the best fit. Also, if you want a whole-house filtration system, this under-sink filter will not cover all your needs. Lastly, if you are not comfortable with basic installation under the sink, you might want to seek professional help or consider an easier-to-install option.

Our Testing Experience

First Impressions

When I first installed the PUREPLUS Under Sink Water Filter System, I was impressed by how compact it was—just 4.5 x 4.5 x 13.7 inches—making it easy to fit under my kitchen sink without any hassle. The direct connect setup was straightforward, and I appreciated that it didn’t require complicated tools or professional help. I was curious to see if it could really deliver on its promise of filtering 22,000 gallons over five years, so I started testing right away by comparing the water taste and smell before and after installation.

Daily Use

Using the filter daily was surprisingly convenient. The flow rate was strong—up to 2.5 gallons per minute—so I never experienced slow water flow, even when filling a large pot. I noticed immediately how much better the water tasted and smelled. The chlorine and any unpleasant odors were almost completely gone, making it much nicer for drinking and cooking. It quickly became part of my daily routine, and I felt confident knowing it was removing heavy metals and other impurities from my tap water.

Key Features in Action

One feature that really stood out was the 6-in-1 composite filter with its 0.5-micron filtration accuracy. From my experience, this meant the water was noticeably cleaner and fresher. The NSF/ANSI 42 certification gave me peace of mind about the quality and safety of the filter. I also liked that the materials were lead-free and BPA-free, which is important for my family’s health. The cost was very reasonable, too—less than two cents a day on average, which is much cheaper than other filters I’ve tried.

Long-Term Performance

After using the PUREPLUS filter for several months, I can say it holds up well over time. The water quality stayed consistently high, and I didn’t notice any drop in flow rate or taste. The filter’s high capacity means I don’t have to worry about frequent replacements, which is a big plus for me. Overall, this system has been reliable, easy to use, and effective, making it a great investment for clean and safe drinking water at home.
