Hydrofast B100 Countertop Reverse Osmosis Water Purifier

No Installation & Countertop Convenience
The Hydrofast B100 countertop water purifier requires no installation or plumbing, making it easy to use right out of the box. Its compact design makes it perfect for any countertop in kitchens, living rooms, offices, and RVs. You can access purified water immediately by simply connecting it to a power source.

Eco-Friendly & Low-Maintenance
The innovative filtration technology of the Hydrofast B100 water filter boasts a 3:1 pure-to-drain ratio, much higher than others, minimizing water wastage while maximizing efficiency and prolonging the lifespan of the RO filter, which provides up to 12 months of use, with a self-cleaning function to extend its lifespan. Unlike other brands that require multiple filter replacements, Hydrofast simplifies maintenance with a single-filter replacement system—just twist and pull to replace it in seconds.

Smart Display & User-Friendly Design
The B100 water purifier features a smart display with four quick volume selections: 100/250/450/600 ml (3.5/8.7/16/21 oz). It shows real-time water capacity, catering to your various drinking needs. The instant TDS readings enhance drinking safety, while the cartridge life indicator keeps you informed about the filter’s status, allowing for timely replacement. When not in use, the B100 purifier automatically enters a power-saving standby mode to minimize energy consumption.

Convenient Hydration, Sustainable Lifestyle
Designed for households of 2 to 3 people, the Hydrofast RO water filter obtains a spacious 4L (1.06 Gal) water tank and a rapid flow rate of 100 GPD, ensuring that you can enjoy pure water anytime. The composite quick-change rotary cartridges in the B100 household water purifier can filter up to 1,056 gallons of pure water—equivalent to approximately 8,000 bottles—significantly cutting down on plastic waste and saving money.
