Waterdrop Water Filter System (Open Box)

I've been using my Waterdrop RO countertop filter for 22 months (bought in Aug 2023). I make anywhere between 1 and 8 gallons of water daily. I provide filtered water to several family members. I also make all of my daily ice with this water (via the new Frigidaire crushed ice machine). I store my filtered water in 1 gal containers. My father-in-law puts his water in the fridge using a 2 gal dispenser so he always has cold water ready to go. I do the same with a 1 gal jug from Amazon. I just replaced my filter for the very FIRST time one week ago (after 21+ months of use). Here's how I think I got so much value from the original filter: I always pull my feed water from my fridge filtered water. The idea being that it provides semi-filtered water as input into my RO filter, keeping the "big chunks" out of my RO filter. It seems to have worked well. Customer Service: I had one issue with my Waterdrop filter 2 weeks ago. The handle for the feed water tank cracked then broke. I reached out to Waterdrop to see if I could replace the handle. They offered to send me a replacement handle at no cost! Then I was told they would be sending me a completely new feed water tank with the handle already installed at no cost to me. THAT'S CUSTOMER SERVICE. I LOVE my Waterdrop RO filter. The water tastes great (cold smooth water with no real "taste" at all). My experience is proof that this unit keeps working day after day with no issues (other than that above). I estimate that I've made over 1,300 gallons of water in the past 22 months. The only real mistake I've made is dispensing water into an already full container mindlessly making a nice little mess to clean up!
