Independent water filter guide
Choosing a water filter for an apartment
Apartment filtration is often a space and installation problem before it is a product problem.
Countertop systems are easier to move
A countertop RO dispenser can be attractive for renters because many models avoid permanent under sink installation. The tradeoff is counter space and the need to refill a source tank.
Under sink systems can still work
If your lease and plumbing setup allow it, an under sink system keeps the counter clear. Confirm installation requirements before drilling or changing plumbing.
