Our take on the Waterdrop CTF-01

The Waterdrop CTF-01 is a five-stage countertop water filter that connects to your faucet and needs no plumbing work. Its main selling point is a long 12-month, 8,000-gallon cartridge life, which cuts how often you swap filters compared with many countertop rivals. Flow tops out at 1.6 gpm, so it fills a glass quickly but is slower than an under-sink system. It suits renters and anyone who wants better-tasting tap water without installing anything.

Questions and answers

How often do I change the filter?
The cartridge is rated for 12 months or 8,000 gallons, whichever comes first. Heavy use will hit the gallon limit sooner.
Does it remove fluoride?
Waterdrop lists the CTF-01 as a five-stage filter aimed at chlorine, sediment, taste and odor. Check the spec sheet for the exact contaminant list before buying if fluoride is your concern.
Will it fit my faucet?
It attaches to standard threaded faucets. Pull-down and pull-out sprayer faucets usually need an adapter or won't work.
Is it better than an under-sink filter?
It installs in minutes and needs no drilling, but under-sink systems flow faster and stay out of sight. Choose the CTF-01 if you rent or want a quick setup.
Does it need electricity?
No. It runs on faucet water pressure only, so there is nothing to plug in.
Where is the Waterdrop CTF-01 cheapest?
At Home Depot, for $59.99, as of our latest check.
Where can I buy the Waterdrop CTF-01?
6 stores we checked sell it, including Best Buy, Home Depot, eBay, Waterdrop Official, Lowe's.
