#7 Waterdrop WD-FC-01 Water Filter Faucet

Waterdrop WD-FC-01 Water Filter Faucet

Another product from Waterdrop, Waterdrop WD-FC-01 Water Filter Faucet is a variant of the water filter we had mentioned earlier. However, this one trades a few features for saving you some money in the long run. Rest assured, though, installing this water filter faucet will be an easy task, given that you have a mount that is compatible. There are also dedicated buttons that help you get the idea of how to use the filter with the lower hassle.

The multi-stage filtration system in the Waterdrop WD-FC-01 Water Filter Faucet claims to remove up to 93% of chlorine from source water feed. In addition, you can also get rid of fluoride particles, lead and some other dust contaminants. The system, however, does not do much to the taste of the water. So, if you are getting really non-tasty water from the feed, you need something more powerful.

Filtration capacity in the Waterdrop WD-FC-01 Water Filter Faucet is impressive enough. You are looking at 320 gallons per filter, which means you have to replace it once in three months or so. However, it depends on how often you use the filter. Now, keeping things up to the standard, the filter offers a standard flow rate of just 0.5 gallons per minute.

Now that you have seen the best faucet water filters out there, shall we talk about picking the right one?

Faucet Water Filter Buying Guide

Let’s talk about some important aspects of a faucet water filter.

Factors to Consider

You should pay attention to the following aspects if you want to purchase one of the best faucet water filters out there.

Size: Given that you don’t want to give it too much space, you should consider the amount of space a faucet water filter takes up. This depends on your requirement too. For instance, if you are looking for an extensive filtration system, you will have to pick a bigger faucet.

Capacity: Of course, you should check the amount of water a faucet filter can give you. This is where you will have to spend more money, remember. So, it’s recommended that you pick a faucet system that runs filters with higher capacity.

Design: There are two major aspects to design: convenience and aesthetics. Convenience refers to whether you can use the product in the best way possible. On the other hand, Aesthetics is about how the faucet can become a part of your kitchen.

Filtration Technology: is also an important aspect you should check while going for a faucet water filter. There are filter faucets with a variety of technologies, including but not limited to Activated Carbon Fiber and UV membrane.

Additional Features: You should also see if additional features are included in the package. For instance, it makes sense to have a filter replacement indicator and a toggle switch. These features will help you ensure clean water and save water respectively.

Pricing: As you can see, faucet water filters are available in all the price ranges. Depending on your priority — saving some money or getting top-of-the-class cleaning —, you can make the right choice. We’d suggest no compromises on quality though.

How Does Water Filter Faucets Work?

Water filter faucets work almost like normal water filters work. However, there are some differences when it comes to the requisites. For instance, water pressure isn’t much of an issue here. Instead, the water from your feed is let through the filter, which may have one or many filters.

Through these steps, the water would be filtered and various contaminants would be removed. After that, the clean water flows through an outlet. Normally, water filter faucets are attached to the spout and will have a dedicated button. Using this button, you can decide whether you want filtered water or not.

After some time, the filter may face wear and tear and you will have to replace it. This is often an easy task and won’t take more than a few seconds. As you see, compared to fully-fledged counter-top or under-sink filters, water faucet filters are easy to use and maintain.

The Benefits

The biggest benefit of a water faucet filter is the convenience it offers. You don’t have to spend a lot of space or time to maintain the system. Instead, it silently attaches to your faucet spout and gives you clean water, at good rates.

Despite the small size, faucet water filters are really powerful at removing contaminants from water. There are systems that can remove lead, fluorides, chlorine and other form of potential damages from the public water supply you are getting.

Also, did we say that faucet water filters are easy to maintain? You can take these wherever you want and they mostly fit the normal faucets there. Installation does not require extra tools and you need not be a plumbing expert either.


The actual answer depends on the particular type and brand of the faucet filter that you are buying. In most of the cases, however, you don’t need additional tools to install something like this. Instead, the faucet filter is connected to the normal faucet in the sink to enable the flow of water.

Once that’s done, you could use a knob or a button to turn on the filter. Once enabled, you will be getting filtered water through the dedicated outlet in the system. That’s about the installation process. Whenever you have to change the filter, you can do that by following the procedure mentioned in the user guide.

In most of the products we have covered before, you can spot a dedicated indicator for the filter status. You will be notified when the filter has reached its maximum cycles. At that time, you have to purchase a fresh filter and replace the old one.

Cleaning and Replacement

Just like the installation process, cleaning and replacement of the faucet filter is also easy. As we said above, you will have to purchase a compatible filter in the first place. Then, you can simply take out the previous one and pop in the new filter.

Cleaning won’t also be a concern if you are changing the filters in the recommended intervals. It’s always to stay ahead of the deadlines here. For instance, if a filter says it will last for three months, you should think about changing it when you are using it for two and a half months.

Once again, the final words depend upon the type of faucet you are using. Different brands may be following different methods to do it.
