VonWater CT910G vs CT910 Key Specs
Included Filters
The CT910G model ships with one filter, providing a standard initial filtration setup. In contrast, the CT910 bundle includes two RO filters. This inclusion extends the total filter life up to four years, covering a capacity of 1056 gallons. You get double the lifespan right out of the box with the CT910. This reduces the frequency of replacement hassle and offers longer-term reliability for households. The CT910G requires you to purchase the replacement filter separately, identified as CT100-RO, while the CT910 uses the CT910WF replacement. For buyers seeking minimal immediate maintenance, the CT910 provides a clear advantage in included value and extended service intervals.
Dispensing Options

Physical Dimensions
