💡 Features

Activated Carbon Filter

The Waterdrop faucet filtration system’s activated carbon filter has a 0.5-micron rating and is NSF-certified to trap contaminants including chlorine and other contaminants, producing water that is cleaner and better-tasting.

6 adapters

This Waterdrop filter comes with 6 different adapters for fitting the unit to your kitchen sink faucet. 3 of these adapters are designed for internal threaded faucets, and the other three are designed for external threaded faucets. Each adapter comes with a washer which should be used in installation.

The mounting base attaches the filter’s main filter unit to the faucet adapter. It is designed to screw easily into place at the faucet.

Filter housing

The filter housing unit attaches onto the mounting base. It protects the filter from external damage and keeps the filter firmly in place.

Waterdrop Water Faucet Filtration System features

🚦 Performance

The standout performance feature of the Waterdrop water faucet filtration system is its speed when filtering water. You can expect the majority of faucet water filters to quickly filter water, as they’re assisted by the water pressure coming from the faucet, but the Waterdrop filter works particularly effective to get the job done. You will only notice a reduced rate of water flow when it’s time for a filter change.

In terms of efficiency, this Waterdrop system will offer you more value for your money with its longer-lasting filter.

Keep in mind, though, that if you purchase a replacement filter that isn’t from the manufacturer, it’s unlikely to last as long. You can buy replacement filters from Waterdrop, and they do cost slightly more than most filter replacements, but still work out at a better value for the extra few weeks of filtration you get.

🔧 Installation & Maintenance

The Waterdrop faucet filtration system fits most standard faucets, and can work with the most typical faucet aerator sizes.

To install the water filter, first identify your faucet type (note that the filter doesn’t fit on pull-out, spray style or hand-held faucets, or faucets with a sensor) and determine whether you will need to use one of the supplied adapters.

Next, remove the aerator from the faucet and select your adapter if necessary. The manufacturer has produced a handy video on which adapter to choose based on your faucet type.

Then screw the mounting base to the faucet and attach your filter housing. Make sure the filter cartridge itself has had its outer packaging removed.

Looking after the Waterdrop faucet filtration system and preserving its life is simply a case of making sure to replace the filter when necessary. You should notice that water flow is weak when the filter needs changing.

📝 Filter Info

The filter in this Waterdrop system is NSF-certified to reduce both chlorine.

With multi-stage filtration, the Waterdrop water faucet filtration system’s filter can work to target a broader range of contaminants than similar models.

It uses preliminary stainless steel mesh to trap larger particles, followed by a pre-sediment layer that filters sand, rust, and other small particles.

The main activated carbon fiber layer removes up to 93% chlorine with the the advanced filtration layer. Finally, the post-filtration layer and stainless steel mesh further reduce any suspended particles in water.

The filter cartridge lasts slightly longer than other filters – roughly about a month. This is likely because the filter has pre-filter layers to catch the larger particles and prevent them from clogging the carbon fiber layer.

You will need to change the filter after roughly 320 gallons of use, or when water starts to flow out of the filter at a reduced rate.
