Waterdrop RO membrane filter replacement

Mark H.—November 30, 2025✓ Verified purchase

These RO membranes are on a timer set for a 2 year change interval. My TDS meter reading was slowly climbing. Changing the 2 other filters did not cause the TDS readings to drop. After 1.5 years I replaced the membrane filter. The TDS reading dropped back down to 2-3. Take away : The filter change light is just a suggestion. Depending on the supply water quality and how much water you have made you may want to consider replacing the filter sooner. Read more

Easy to replace, great tasting water — stock up on sales!

Kia Sri—July 7, 2025✓ Verified purchase

The Waterdrop RO filter refill is fantastic. It’s super easy to replace — just a quick swap and you’re done, no hassle. The water tastes excellent, clean, and fresh every time, which makes it so much easier to drink more water at home. I usually buy the filters on sale on Amazon, which helps keep the cost down, and having them on hand means I never have to worry about running out or drinking anything less than great-tasting water. Highly recommend if you want an easy way to keep your RO system running perfectly and enjoy clean, delicious drinking water all the time! Read more

Great water, easily

Roger bivins—January 12, 2025✓ Verified purchase

I've been using this system for 9 months now and continue to appreciate almost everything about it. The taste of the water has spoiled me so much that I now find the taste of my old preferred brand of bottled water unpleasant. The digital screen on the water faucet provides advanced notice as each filter needs replacement. The filters are simple to replace by twisting 1/4 turn to unlock, remove / replace with no need to shut off the water supply ect. After replacement, the system automatically cycles and flushes the new filter cartridge. No more humping cases of bottled drinking water and 5 gal jugs of coffee water. Just makes life a little easier. Read more

Easy Install and decreased TDS number immediately

italianlancer08—June 11, 2025✓ Verified purchase

Fits my Waterdrop G3 600 gpd system and dropped the TDS from the low twenties to the single digits upon installation. Easy install too. Just twist the old one out and put the new one in. Read more
