Daily Use Experience with the 20-Cup Water Filter Dispenser

I’ve had the ZeroWater 20-Cup Ready-Pour Water Filter Dispenser for several months now, and it’s become an essential part of my kitchen. Living in an area with notoriously hard water, I needed a reliable filtration system that didn’t cost a fortune or take up too much space. This dispenser ticked many of the right boxes, though it’s not perfect. Here’s my take on its performance from daily use.

Features and Usability

The five-stage filtration system is undoubtedly the star of the show. This isn’t just a marketing gimmick; the included Total Dissolved Solids (TDS) meter consistently reads zero after filtration. I ran tests on my city’s tap water, which initially had a TDS reading of over 300. After running it through this filter, the meter read zero every time. How cool is that?

Beyond the filtration, the dispenser itself is compact yet holds a generous 20 cups of water. It fits neatly on my countertop and doesn’t hog space. The Ready-Pour technology is a nice touch—being able to pour water while the reservoir is still filtering is surprisingly convenient. It saves time, especially when everyone in the house is trying to fill up their reusable bottles in the morning before work or school.

However, the spigot design leaves room for improvement. Holding down the button to dispense water isn’t the most ergonomic when filling larger containers. My thumb gets sore if I’m trying to fill my half-gallon jug for the gym. A locking mechanism would have been a lifesaver here.

Filtration Performance

This water filter performs exceptionally well in removing contaminants. It’s IAPMO certified to reduce lead, chromium, PFOA/PFOS, and other harmful chemicals. I’ve noticed a drastic improvement in water taste. No more chlorine smell or odd metallic tangs that used to bother me before I started using this dispenser. The water tastes clean and crisp—almost bottled-water quality.

One downside, though, is the lifespan of the filters. With my high TDS water, the filters last around two to three weeks before the TDS meter shows readings above zero. Replacing them this frequently can get pricey, especially if you’re filtering large quantities of water daily. Additionally, some users have reported a metallic or lemony taste when filters near the end of their life. I’ve experienced this once, and it was a clear sign to replace the cartridge.

Build Quality and Design

I found the build quality solid for the most part. The BPA-free plastic feels durable, and the ergonomic handle makes it easy to lift and pour. That said, screwing in the filter requires some effort to ensure a tight seal. If not done properly, water can bypass the filter and leak into the lower reservoir. I learned this the hard way during my first setup attempt.

Cleaning is straightforward. The unit comes apart easily, and I run the non-filter parts through the dishwasher each time I replace the filter to keep things sanitary. However, the upper reservoir sometimes lets water pool without draining entirely, which slows down the overall filtration process. Pressing on the filter a few times usually gets it going again, but it’s a minor inconvenience.

Pros

• Exceptional Filtration: Removes virtually all dissolved solids, leaving water with a TDS reading of zero.
• Spacious Design: Holds up to 20 cups, ideal for families or small offices.
• Improved Taste: Removes chlorine, lead, and other contaminants for clean, fresh-tasting water.
• Easy Monitoring: Includes a TDS meter to track filter performance.
• Compact and BPA-Free: Fits well in kitchen setups and is made of safe materials.

Cons

• Short Filter Lifespan: High TDS water reduces the filter’s efficiency, leading to frequent replacements.
• Ergonomic Issues: Spigot button can be uncomfortable for prolonged use.
• Slow Filtration: Occasionally stalls if water pools in the upper reservoir.
• Pricey Filters: Replacement filters can add up over time.
• Setup Challenges: Requires effort to screw the filter tightly to avoid leaks.

Comparison to Competitors

The ZeroWater dispenser outshines its competitors like Brita and PUR in filtration performance. Neither Brita nor PUR consistently achieves a zero TDS reading, making this product stand out for those who prioritize purity. However, Brita’s filters tend to last longer and cost less, which may appeal to budget-conscious users. Brita also features a more ergonomic spigot design.

When compared to larger systems like reverse osmosis units, this dispenser offers a more compact and affordable solution. That said, reverse osmosis systems often have a longer filter life and don’t require as frequent maintenance. But they’re also more expensive upfront and need professional installation.

Cost Analysis and Value for Money

While the upfront cost of this dispenser is reasonable, the ongoing expense of replacement filters adds up quickly if you have high TDS water like mine. Each filter lasts about 10-15 gallons in my case, which isn’t ideal. For households with lower TDS levels, you’ll get a better lifespan and more value for money.

That said, the dispenser’s ability to produce water with zero dissolved solids is hard to match in this price range. It’s a worthwhile investment for anyone serious about water quality, but it’s essential to factor in the recurring filter costs when making your decision.
