Under-sink RO means tapping into plumbing, which rules it out for many renters and dorm rooms. A countertop unit like the Waterdrop M6H skips that: you pour tap water into the tank, plug it in and it starts working.
The feed tank holds 135 oz and the waste tank 50 oz, and the two stay in separate compartments so waste water cannot flow back into clean water. The 3:1 pure-to-drain ratio is better than the 1:4 many older RO systems use.
The M6H weighs 22 lb and measures 15.9 by 9.3 by 14.5 inches, so it sits beside a coffee maker on a standard counter. Its rated output is 75 gallons per day, enough for drinking and cooking in a small household.
Waterdrop positions it for apartments, offices and RVs, and the product photos show it on a console in a living room. The detachable glass pitcher goes straight into the fridge.
The store lists the M6 under NSF/ANSI 58 and 372. The $70 off on the hot M6 model makes it one of the cheaper ways into countertop RO right now, and it comes with a 30-day return window.

Do I need a plumber for the M6H?
No. The product page says you fill the water tank and plug it in. There is no drilling and no connection to your water line.
Where does the waste water go?
Into a dedicated 50 oz tank kept separate from the clean water. You can pour it on plants or use it for cleaning.
How much water does it make?
The rated flow is 75 gallons per day, which fits a small household rather than a large family.
Is it small enough for a counter?
It measures 15.9 by 9.3 by 14.5 inches and weighs 22 lb, so it suits a counter or a sturdy table, and it needs an outlet nearby.
