Overview
The Apec Water RO-CTOP-C is a countertop reverse osmosis filtration system with an aluminum build, rated for 90 gallons of capacity. It measures 15.5 x 6.5 x 6.5 inches and weighs 10 lb.
As a countertop unit, it sits on the kitchen counter and connects to the faucet rather than requiring under-sink plumbing, which suits renters or anyone who wants to avoid drilling or permanent installation. Its 90 gallon rated capacity is notably lower than the 500 gallon under-sink RO system elsewhere in this batch, reflecting the smaller footprint and no-install design tradeoff.

Who it's for
Renters and apartment dwellers who want reverse osmosis filtration without under-sink plumbing work. Not the pick for households wanting the highest capacity between changes, since 90 gallons is on the lower end for RO systems.
Pros and cons
- No under-sink installation required
- Reverse osmosis filtration in a countertop form
- Aluminum housing at a moveable 10 lb
- 90 gallon capacity lower than under-sink RO systems
- Takes up counter space
Performance notes
Like other reverse osmosis systems, it pushes water through a membrane to reduce dissolved solids beyond what carbon filtration alone catches. The aluminum housing and 10 lb weight keep it light enough to move or store, and the 15.5 x 6.5 x 6.5 inch footprint sits on a standard counter rather than requiring cabinet space.
