What Is Cloud Water Filters and Who Is It For?
Cloud Water Filters is a home water filter brand built around one main product: Cloud RO, an under-sink reverse osmosis system. According to its spec page, Cloud RO uses multi-stage RO filtration with an integrated alkaline post filter, lists a 98% TDS reduction rate and a 1:1 waste ratio. The company says the system removes 99% of the toxins in tap water and adds back essential minerals.
Cloud RO also has a connected side. A Bluetooth app shows filter status and water quality, and Cloud can auto-ship replacement filters based on how much water you actually use. That means less guessing about when a filter is due.
Cloud Water Filters is a great fit for:
- Homeowners who want a permanent under-sink RO system rather than a pitcher or countertop unit.
- App-minded buyers who like checking filter status and water quality on their phone.
- Busy households that would rather have filters auto-shipped than track change dates.
- Long-term planners who value a 5-year warranty on a bigger purchase.
Cloud Water Filters Review: Key Features
What Does Cloud RO Filter Out?
According to its spec page, Cloud RO uses multi-stage reverse osmosis filtration. The company says it removes 99% of the toxins in tap water, and its spec page lists a 98% TDS reduction rate. The spec page lists an integrated alkaline post filter, and Cloud says the system adds back essential minerals. A full list of the specific contaminants each stage targets is not stated on the pages we read, so check the spec page if you have a particular concern about your local water.
How Much Water Does Cloud RO Waste?
The spec page lists a 1:1 waste ratio. Reverse osmosis systems send some water to the drain as part of the process, so a stated ratio helps you plan. Flow rate and tank details are not stated on the pages we read; check the spec page before you buy if those matter for your kitchen.
How Does the Cloud App Work?
Cloud RO connects to a Bluetooth app that shows filter status and water quality. Cloud can also auto-ship replacement filters based on your usage, so a new filter arrives when your household actually needs one rather than on a fixed calendar. For many buyers this is the main reason to choose Cloud over a basic under-sink unit.
Is Cloud RO Certified?
The company says Cloud RO recently received NSF 58 certification for complete system performance. NSF 58 is the standard that applies to reverse osmosis drinking water systems. If certification is part of your decision, the brand’s own pages are the place to confirm the details.
