DREO is positioning its RO Water Filter 113S as a convenient alternative to traditional reverse osmosis systems, combining multi-stage water filtration, automatic pitcher refilling, smart app connectivity, and a compact countertop design. The appliance is designed for households that want access to purified water without plumbing modifications, drilling, or a complicated installation process.
The DREO RO Water Filter 113S features a seven-stage reverse osmosis filtration system, a 5-liter raw water tank, and two portable 1.1-liter borosilicate glass pitchers. It also includes real-time total dissolved solids (TDS) monitoring, automatic self-cleaning, and an integrated IoT system that allows users to monitor water consumption and filter life through the DREO app.
The company says the system removes 99.99 percent of contaminants and can process up to 1,000 liters of water with a single composite filter. Here’s a closer look at its features, specifications, and what makes it different from conventional countertop water filters.
Seven-Stage Reverse Osmosis Filtration System
Filtration is the central feature of the DREO RO Water Filter 113S. The appliance uses a seven-stage composite filtration system designed to reduce contaminants and improve water purity.
The seven filtration stages are:
- External APCM: The first filtration stage.
- PP Cotton (5μm): Helps capture particles and sediment.
- Internal Coconut Shell Activated Carbon: Provides an activated-carbon filtration stage.
- RO Cartridge (0.0001μm): The reverse osmosis membrane forms the central part of the purification process.
- Internal APCM: Adds another filtration stage.
- External Coconut Shell Activated Carbon: Provides additional activated-carbon filtration.
- PP Cotton (5μm): Completes the seven-stage process.
DREO claims the system removes 99.99 percent of contaminants and addresses more than 1,000 impurities. The product deck also states that its reverse osmosis membrane filters bacteria and heavy metals as small as 0.0001 microns.
The company further reports a 92 percent desalination rate, which it says outperforms conventional water filters. The system is presented as meeting NSF/ANSI 58 standards, with testing and verification by SGS, according to the product materials.
Filter Lifespan and Long-Term Running Costs
DREO emphasizes the filter’s capacity and potential environmental benefits. According to the company, one RO composite filter can purify up to 265 gallons (1,000 liters) of water.
The company equates this output to approximately 2,000 plastic bottles, based on bottles holding 16.9 ounces (500ml) each. Its product materials also cite a cost of approximately $0.025 per bottle.
The stated filter lifespan is six to 12 months, depending on usage and water conditions. This means users will eventually need to replace the composite filter to maintain the system’s intended performance.
For households that regularly purchase bottled water, the 113S offers a way to produce filtered water at home while potentially reducing disposable bottle consumption. Actual savings will depend on household water usage, replacement-filter costs, and the price of bottled water in the user’s area.
Automatic Pitcher Refilling Reduces Manual Work
One of the DREO RO Water Filter 113S’s most distinctive features is its automatic pitcher-refill system.
Traditional countertop water filters often require users to pour water manually into a separate container. DREO’s system is designed to automate that process by detecting the water level in the pitcher and refilling it when necessary.
The appliance uses a precise water-level sensor to determine when the pitcher needs more purified water. With two pitchers included, users can keep one positioned on the appliance while taking the other to a dining area, office, or refrigerator.
DREO says the system can refill a full 1.1-liter pitcher in approximately four minutes. Its stated purification speed is at least 260ml per minute before filter expiration and at least 200ml per minute afterward.
This automatic arrangement is intended to make purified water more readily available throughout the day without requiring users to repeatedly operate the appliance.
Real-Time TDS Monitoring Shows Water Readings
The 113S includes separate sensors for monitoring total dissolved solids in raw and purified water.
TDS readings are displayed directly on the appliance’s screen, allowing users to compare the measurements before and after filtration. The feature provides a convenient way to monitor changes in dissolved-solids readings during everyday use.
The display also provides several operating indicators, including raw and pure water TDS information, clean-tank status, empty and refill notifications, and filter-life information.
A dedicated information button and LED control panel provide access to the appliance’s basic controls and status information.
However, TDS readings should not be treated as a complete measurement of water safety. They indicate the concentration of dissolved substances but do not independently identify every possible contaminant. The filtration claims and applicable testing standards remain important when evaluating the appliance.
Two BPA-Free Borosilicate Glass Pitchers
DREO includes two removable 1.1-liter pitchers made from high-borosilicate glass. The company describes them as BPA-free and says the material is designed to avoid plastic odors and secondary leaching.
The transparent glass construction allows users to see the water inside, while the product materials highlight its resistance to thermal shock.
Having two pitchers provides additional flexibility. One can stay on the appliance for automatic refilling while the other is used for serving or kept chilled in the refrigerator.
For households that prefer glass water containers over plastic pitchers, this is an important part of the 113S package.
Smart App Connectivity and Water Consumption Tracking
The DREO RO Water Filter 113S includes built-in IoT connectivity and works with the DREO app.
Through the app, users can monitor water consumption statistics, check the filter’s remaining life, and receive reminders when a replacement is needed. The product materials also describe a dashboard that tracks water usage over daily and weekly periods.
DREO highlights an environmental impact section that estimates the number of plastic bottles saved, money saved, and trees planted. These figures are intended to help users understand the potential impact of using the purifier over time.
The company says water consumption data is updated every 30 minutes. This gives users a way to monitor usage without relying exclusively on the appliance’s physical display.
Built-In Self-Cleaning Flushes the Filtration System
Maintenance is another area addressed by the DREO RO Water Filter 113S. The appliance features an automatic self-cleaning mechanism that activates after each operation.
According to DREO, the system flushes fresh water through the reverse osmosis filter in approximately five seconds, directing impurities into the wastewater tank. The process is designed to minimize residue buildup and help maintain filtration efficiency.
The appliance also features a clean-tank indicator, allowing users to monitor when the wastewater tank needs attention.
Although the automatic flushing feature can reduce some routine maintenance work, it does not eliminate the need to clean the removable tank and pitchers or replace the filter when required.
3:1 Pure-to-Drain Ratio Reduces Water Waste
Reverse osmosis systems typically produce wastewater during the purification process. DREO says the 113S uses an optimized raw water tank design to achieve a 3:1 pure-to-drain ratio.
This means the system is designed to produce three parts purified water for every one part directed to the wastewater tank.
DREO presents this as an improvement over conventional RO systems that can waste more water during filtration. The company says the design reduces water loss while improving overall efficiency.
For households concerned about water consumption, the stated ratio is an important specification to consider when comparing the 113S with other reverse osmosis appliances.
