In this comprehensive Waterdrop WD-CTF-01 Countertop Water Filter review, we will analyze the filtration capabilities, the system capacity & longevity, its flow rate, the installation & maintenance process, and discuss customer reviews and potential alternatives for this countertop water filter system.
Let’s get started!
Waterdrop WD-CTF-01 Countertop Water Filter Overview
The Waterdrop WD-CTF-01 Countertop is a typical countertop water filtration system that is really to install and use, as you only need to assemble the device and connect the diverter to the sink faucet. After that, to get filtered water you just need to turn on the faucet and turn the diverter valve so that the water runs through the system to be filtered out.
This water filter uses a 5-stage filtration process to remove several different types of contaminants from the water.
The Waterdrop WD-CTF-01 Countertop Water Filter is made of 1mm thickened food-grade 304 stainless steel, making it not only nice looking to fit in your kitchen (or other location where you might want to use it) but also safe to use, as it is also BPA and lead-free.
As we will cover in more detail in the sections below, this countertop water filter also includes a remineralization stage to ensure that your water has all the necessary minerals, and delivers a nice 1.6 GPM flow rate to ensure that you won’t have to wait for clean water.
Another factor worth mentioning that distinguishes the Waterdrop WD-CTF-01 from most other countertop water filters is its high capacity to filter up to 8.000 gallons of water, which means it will last years until you have to replace its filters.
Waterdrop WD-CTF-01 Countertop Water Filter Filtration Capabilities
The Waterdrop WD-CTF-01 Countertop reduces up to 99% of different contaminants from water, like chlorine, bacteria, VOCs, fluoride, heavy metals (lead, mercury, arsenic, hydrogen sulfide, etc.), sediments, rust, bad taste & odors, and more.
This outstanding filtration power is achieved through 5-stages of filtration:
- Stage 1: Activated carbon to remove chlorine and bad taste and odors
- Stage 2: KDF filter to remove bacteria, microorganisms, and heavy metals
- Stage 3: Polyester membrane to filter out sediments and larger particles
- Stage 4: Mineral filtration to add back healthy minerals like calcium, magnesium, and potassium
- Stage 5: PP membrane that improves the water taste and removes any remaining bad taste and odors

Waterdrop WD-CTF-01 Countertop Water Filter Capacity & Longevity
The Waterdrop WD-CTF-01 Countertop Water Filter has a high capacity as it can filter up to 8.000 gallons of water. Compared with other top countertop water filtration systems, this system has one of the highest capacities that we have seen.
This type of capacity usually ensures a few years of filter longevity, but Waterdrop recommends that you replace the filter every year to ensure maximum performance.
But even if you replace the filter every year, you still save much more than with other countertop water filters that need the filters to be replaced every 3 to 6 months.

Waterdrop WD-CTF-01 Countertop Water Filter Flow Rate
When choosing a countertop water filter for you, it is important to consider its flow rate to know how much time it will take to filter the amount of water that you and your family will need.
The Waterdrop WD-CTF-01 Countertop water filter has a great flow rate of 1.6 GPM (equivalent to 6L per minute) which means it can fill a 200 ml glass of water in just 2 seconds. With this water flow, you will never have to wait to get access to clean and fresh water.
Compared with other countertop water filters, the Waterdrop WD-CTF-01 Countertop has one of the best water flows between the top filters of this type.
Waterdrop WD-CTF-01 Countertop Water Filter Remineralization
Lately, customers have been more concerned, and correctly so, with the remineralization capabilities of the water filters.
Some of the most powerful filters will remove not only contaminants from the water but also some beneficial minerals from it. While this shouldn’t be a problem if you have a balanced diet, it is always good to get these healthy minerals from the water you drink.
Taking this into consideration, Waterdrop WD-CTF-01 Countertop Water Filter has a remineralization stage during its filtration process to ensure that good minerals like calcium, magnesium, and potassium are added back to the water.
This remineralizes the water that might have lost some of these minerals in earlier stages of the filtration process, making the water healthier and tastier.
Waterdrop WD-CTF-01 Countertop Water Filter Installation & Maintenance
The Waterdrop WD-CTF-01 Countertop Water Filter comes with all the necessary items to ensure that you can complete the installation in minutes and by yourself, as it comes with a wrench, some adaptors, and a user manual (that you can also find on their website).
To perform the installation of this countertop water filter just assemble the device, connect the diverter to your faucet using one of the available adapters, and then the system will be ready to go.
Just take into consideration that some non-standard faucets, like spray, pull-out, hand-held, or sensor-based might not fit into the Waterdrop WD-CTF-01 Countertop Water Filter. In the image below from Waterdrop, you can find in more detail which faucets are not supported.
