About Cloud Water Filter

Tap water is supposed to be safe, but for many people, it’s a daily source of concern. Whether it’s PFAS, lead, or old pipes that haven’t been replaced in decades, there’s a growing awareness that what’s in the water might not match what’s on the report. Basic filters help a little, but they often leave behind the worst contaminants and offer no way to know how well they’re actually working.

Cloud Water Filters was created in response to that problem. The company is based in California and focuses on building water systems for the way people live now. Their team combines experience in home tech, health, and sustainability to create products that aim to take the uncertainty out of everyday drinking water.

The Cloud system tackles more than the usual suspects. It removes a wide list of harmful substances, adds back essential minerals, and lets users track everything through an app. The setup is compact, runs on a battery, and is made to fit easily under the sink without needing complicated tools or electrical work.

But can one compact system really do all of that? We’re going to walk through exactly what Cloud offers and see how well the product holds up when you look past the marketing.

Highlights

• Cloud RO removes up to 99% of contaminants including PFAS, lead, fluoride, microplastics, VOCs, and more.
• It produces clean, alkaline water by adding back minerals like calcium, magnesium, potassium, and zinc.
• Real-time tracking through the Cloud app shows water quality, filter life, usage, and local toxin data.
• The compact, modular system is easy to install in under an hour without needing electrical work.
• Filter replacements are simple with a countertop magazine-style design that requires no tools or plumbing.
• With a 1:1 waste ratio, Cloud uses significantly less water than traditional reverse osmosis systems.

Cloud Water Filter Review

Water quality is no longer something people can afford to ignore. With aging infrastructure, chemical contamination, and limited regulation of newer threats like PFAS, even basic tap water raises concerns. Let’s look at what makes Cloud different, what you actually get from using it, and how the pricing breaks down.

Unique Features

Cloud RO is built with a mix of smart technology, high-performance filtration, and thoughtful design that sets it apart from traditional RO systems and basic filters. Here’s a closer look at the standout features that define the product.

1. Multi-Stage Filtration with Remineralization

The system filters water through four distinct stages. It starts with sediment and carbon filters, followed by a high-performance reverse osmosis membrane. The final stage adds healthy minerals like calcium, magnesium, potassium, and zinc, which help raise the pH and create clean, alkaline water.

2. Real-Time Water Monitoring

The Cloud app gives users detailed insights into their water quality. It tracks total dissolved solids before and after each filtration stage, shows how much water is stored in the tank, and monitors filter condition. Users can also see water quality data based on their zip code, pulled from public sources and lab testing.

3. Battery-Powered Operation

Cloud RO runs entirely on a replaceable battery pack. There is no need to connect the unit to an outlet or deal with electrical wiring. The battery powers all internal sensors and typically lasts for years. A new battery is included in each replacement filter kit.

4. Quick and Flexible Installation

The system arrives with pre-cut tubing and fittings already attached. Its modular build allows users to arrange the components to fit under most sinks. Most households can complete the installation within an hour using only basic tools.

5. Low Waste Ratio

Cloud RO filters water more efficiently than most systems in its category. For every gallon of clean water it produces, only one gallon is discharged. Traditional systems can waste four to ten gallons for every gallon of drinking water, which makes this a significant improvement.

6. Fast Water Flow

Water flows quickly from the dedicated faucet. A standard glass can be filled in under six seconds. The internal pump helps maintain consistent pressure, making the system suitable for larger uses like filling pots or refilling water bottles.

7. Tool-Free Filter Replacement

Changing filters is simple. The filter cartridge housing lifts out from the base and can be replaced on a countertop. There is no need to reach under the sink or disconnect any plumbing. The system stops the water flow automatically during this process for added convenience.

8. Compatible with Fridges and Ice Makers

Cloud RO has enough pressure to supply filtered water to additional outlets in the kitchen. It can connect to a refrigerator, an ice maker, or other secondary points without the need for extra equipment or upgrades.

Benefits

Cloud RO is designed to make water safer, your routine easier, and your home more efficient. These are the real-life improvements users can expect.

1. Cleaner Water Without Uncertainty. The system filters out serious contaminants like lead, fluoride, and PFAS, giving you water that feels safe to drink straight from the tap.
2. Noticeably Better Taste and Texture. Added minerals give the water a smooth, balanced flavor that encourages more frequent and consistent hydration.
3. Clear Visibility Into Water Quality. The app shows you how your system is performing at every stage, from TDS levels to filter life and household consumption.
4. Maintenance That Doesn’t Feel Like a Chore. Replacing filters takes just a few minutes and can be done outside of the cabinet, without tools or plumbing knowledge.
5. Fast Water Delivery for Daily Use. The system fills glasses and bottles quickly, so you’re not waiting around when you need clean water right away.
6. Less Reliance on Bottled Water. Switching to Cloud reduces single-use plastic waste and helps cut down on weekly bottled water purchases.
7. Lower Costs Over Time. The system tracks actual usage, so filters only get replaced when needed, not on a fixed schedule, which keeps ongoing costs predictable.
8. Fits Into Real-World Spaces and Routines. With a compact footprint and flexible setup, Cloud works in small kitchens, rental homes, and busy households without disruption.

Price

Cloud RO is priced at $749, but it’s currently available for $599 with a limited-time $150 discount.

The purchase includes everything you need for setup. That means the full filtration system, holding tank, dedicated faucet, all filters, a battery pack, tubing, fittings, and tools for installation. You don’t need to buy anything separately unless you choose to hire a professional for installation.

Filter replacement costs are around $200 per year for most households. The system tracks water usage and filter performance, so you only replace parts when needed, not on a fixed timeline. This helps avoid overspending on early replacements or running the system with worn-out filters.

Cloud Water Filter Review: What Do Customers Think?

Customers are overwhelmingly positive about Cloud Water Filters, especially when it comes to water taste, ease of installation, and the day-to-day convenience the system provides.

Many say the water tastes noticeably better than what they got from pitcher filters or even older reverse osmosis systems.

“The re-addition of minerals to the Cloud filter water produces a water that is actually delicious.”

Installation is often described as fast and manageable, whether done by a technician, a family member, or the user.

“My son in-law installed my Cloud in about 20 minutes. I am extremely happy with the convenience of having filtered water at my fingertips.”

Users also appreciate not needing to rely on bottled water anymore, which saves money and reduces plastic waste.

“We haven’t bought bottled water since we installed!”

Others point to the overall quality and value, especially compared to older RO units they’ve tried.

“After four months of use, I am incredibly happy with the purchase. From the quality to taste, I feel like I’ve finally found an RO system that… exceeded my expectations.”

In short, people love how Cloud RO fits into their daily lives without hassle, while delivering cleaner, better-tasting water they can trust.

Is Cloud Water Filter Legit?

Yes, Cloud Water Filters is a legitimate brand. They offer a fully certified reverse osmosis system that meets NSF/ANSI 58, 42, and 53 standards — the gold standard for water filtration performance and safety. Their system uses real multi-stage filtration with documented contaminant removal, not vague claims. They provide complete technical specs, lab-tested data, and clear documentation on how their product works. With a one-year guarantee, professional-grade components, and transparent communication about installation, maintenance, and results, Cloud operates like a serious company with nothing to hide.

Is Cloud Water Filter Worth It?

Yes, Cloud Water Filters is worth it. It delivers certified performance through a multi-stage reverse osmosis system that removes 99% of contaminants including PFAS, lead, fluoride, and microplastics. The addition of minerals like calcium and magnesium improves the taste and texture of the water, setting it apart from systems that strip water bare. It’s also one of the few systems that offers real-time monitoring through a connected app, giving users full visibility into water quality, filter life, and overall usage.

What makes Cloud stand out even more is how practical it is for everyday use. Installation is fast and doesn’t require electricity, and filter changes are designed to be quick and mess-free. The system tracks when replacements are actually needed, helping avoid waste and extra cost. It also supports fridge and ice maker connections, uses less water than traditional RO systems, and takes up minimal space under the sink. Between health benefits, convenience, and long-term savings, Cloud offers strong value across the board.

FAQs

Does the Cloud RO system work in areas with hard water?

Yes, the Cloud RO system can be used in homes with hard water, but for best performance and to extend filter life, a pre-treatment system such as a water softener may be recommended. Hard water contains minerals that can build up in filters over time, and while Cloud includes anti-scale protection, addressing extreme hardness at the source can improve long-term efficiency.

Is the system suitable for off-grid homes or cabins?

As long as there is adequate water pressure, the Cloud RO system can be used in off-grid settings. Since it runs on a battery rather than electricity, it doesn’t require an outlet, making it a practical solution for cabins, tiny homes, or other alternative living setups where power access is limited.

What kind of maintenance does the system require beyond filter replacement?

Outside of annual filter changes, the Cloud RO system requires very little ongoing maintenance. The internal sensors track tank pressure and system health, and if the holding tank loses charge or efficiency over time, Cloud recommends swapping it every 2–4 years, which is a simple and low-cost part replacement.

Can the system be used with well water?

The Cloud RO system can be used with well water if the source meets certain conditions. It requires water pressure within the recommended range and pre-treatment for bacterial contamination, if present. Cloud advises testing well waters before installation to ensure compatibility and protect the RO membrane.
