Reveal the Deal →Cloud's countertop reverse-osmosis filter is $50 off right now, dropping to $599 from $649. It's a compact, install-free system that delivers filtered water on the counter, and this is the main standing discount on the unit.
Prefer to pay over time? Cloud offers financing at roughly $47 a month, which makes the countertop system easier to fit into a budget instead of paying the full amount up front.
Cloud backs the filter with a money-back satisfaction guarantee, so you can try it at home and return it if it's not right for you. It takes the risk out of a first-time water-filter purchase.
Every Cloud filter comes with a 5-year warranty, well beyond what most countertop systems offer, which reflects how long the unit is built to last.
Cloud's filtration is NSF certified, meaning its contaminant-reduction claims are independently tested and verified rather than self-reported. Worth checking against your local water report.
Cloud's free tool lets you enter your zip code to see the contaminants reported in your local water system. A useful, no-cost first step whether or not you buy the filter.
When it's time to replace, the 5-pack of replacement filters is $200 and covers the full set the system uses. Buying the full set at once keeps the unit performing and avoids piecemeal ordering.
Cloud uses reverse osmosis in a countertop form factor, so you get RO-level filtration without hiring a plumber or installing under the sink. The how-it-works page walks through the setup and filter stages.
Cloud's whole pitch is replacing single-use plastic water bottles with filtered tap water, and the Cloud app lets you track how many bottles your household has saved. Better water and less plastic waste.
Reverse osmosis is one of the most thorough home filtration methods, reducing a broad range of contaminants. Cloud pairs that with NSF certification so the reduction claims are verified.
Browse Cloud's replacement filters to keep your system running at full performance. Using the brand's own filters preserves the NSF-certified filtration the unit is rated for.

About Cloud Water Filters

The system is NSF certified, backed by a 5-year warranty and a money-back satisfaction guarantee, and pairs with an app that tracks how many single-use plastic bottles your household has replaced.

Cloud vs the competition
Here's a quick look at how Cloud compares with other home water-filter options.
| Cloud ★ | Under-Sink RO | Pitcher Filters | |
|---|---|---|---|
| Filtration | Reverse osmosis | Reverse osmosis | Basic carbon |
| Install | Countertop, none | Plumber often needed | None |
| Certification | NSF certified | Varies | Varies |
| Warranty | 5 years | Varies | None |
💡 Our take: Cloud gives you RO-level filtration without the under-sink install, which is the main reason to pay more than a pitcher.
