Customer Reviews
Consistent quality, returning buyer
This was my third time ordering replacement filter cartridges for my refrigerator. I always get the same ones, and they always arrive quickly and fit perfectly. No issues, no surprises, just reliable service. It's why I keep coming back instead of trying other brands. The subscriptions save a bit too, which is nice.
Great RO system, delivery could be faster
I purchased the tankless reverse osmosis system last month. Installation was straightforward with the included kit, and the water tastes great, much better than before. It feels very sturdy and well-made. The only minor gripe was shipping; it took 5 days to reach Denver from the EU, which felt a little long. I know it's international, but still. Customer service was helpful when I had a question about filter replacement schedules. Overall, a solid product and good value, even with the slightly slower delivery time.
Good first buy, fair price
I grabbed a Waterdrop filter pitcher during a sale. The new customer discount made it a really good deal. Shipping was free too which helped. Got to my place in 4 days. Felt like I got my money's worth for sure.

thinking about grabbing a whole house filter during their black friday sale. do they usually have good deals then, like 30% off or something? and can i stack a new customer code on top of that?
hey, anyone used those tankless RO systems from waterdrop? wondering if they're actually legit or just another gimmick. like, does the water actually taste good and is it really easy to install myself?
