Personally, when my G2 filters are exhausted, I will upgrade to this one for $50 more than the cost of replacement filters:
https://a.co/d/04UmA51E
800 GPD, 3:1 drain ratio, and Standard 58 certified for $200.
The best modern RO purifiers are 3:1, like the $200 Stokk S2 that matches the specs of the much more expensive Waterdrop G3P800. It costs only $50 more to upgrade to this new unit than to buy replacement filters for my G2, so that's what I'm doing.
"The Stokk S2 800 GPD is a high-performance, budget-friendly system that offers double the water production of the Waterdrop G2. While the Waterdrop G2 is a well-established model known for long-term reliability, the Stokk S2 provides much better efficiency and more modern features for a similar price point." - AI summary

1. I got $10 TDS water meter. My area tap water is 250 TDS. Filtered water is 10 TDS.
2. I installed remineralization filter to add mineral and better taste. RO water can taste... sharp and dry.
3. filter cost is not high at all one is CF carbon filter Every year and other one is RO filer every two years.
4. You would need a power outlet to use this machine. MY Apartment only has one outlet.. so I used bluetooth remote switch to control power to Garbage disposal and this water machine is constant on.
5. Never had a issue, leak, problem in 3 years
6. You would need to drill a hole in the sink. this was most pain in the ass process.
