What Is the RiverSoft SF-15?
The RiverSoft SF-15 is a 15-stage shower and tap filter that work as a bathroom water softener. It is built for Indian bathrooms dealing with hard water, chlorine, and impurities from municipal or borewell sources.
Inside the SF-15 is a multi-layer SFC-15 cartridge that combines hard water conditioning, chlorine removal, sediment removal, and odour removal layers. Together, these form 15 stages that help reduce chlorine, sediments, and the impact of hard water salts before water touches your skin and hair.
The product uses standard 1/2-inch connections and can serve a shower or a bathroom tap, making it unusually flexible for a single filter unit.
When to Choose the SF-15
• You want one filter that works for both your shower and bathroom tap.
• You are concerned about hair fall, dry skin, or a flaky scalp caused by hard water and chlorine.
• You prefer to keep your existing shower head and add a filter unit inline.
• You don’t want a costly solution for your hard water problem.
What Is the RiverSoft DIVA-05?
The RiverSoft DIVA-05 is a 15-stage shower filter with an integrated 5-mode shower head, designed specifically for Indian hard water. Rather than adding a filter unit to your existing fitting, DIVA-05 replaces your shower head entirely, combining multi-stage filtration with five adjustable spray modes: rain, mist, massage, mist & massage and rain & mist in a single, modern unit.
Like the SF-15, it uses an SFC-15 cartridge, which contains different layers to reduce the harsh effects of hard water and chlorine on hair and skin. The addition of five spray patterns positions it as the more experience-focused option in the RiverSoft range.
When to Choose the DIVA-05
• Your primary concern is shower water quality for your hair and skin.
• You want a new shower head with 5 spray modes, not just a filter attached to an old fitting.
• You prefer a premium, spa-like shower feel while still addressing hard water and chlorine.
• You live in a rented home and want a noticeable, reversible shower upgrade without changing taps.
Hair and Skin Benefits
Both the SF-15 and DIVA-05 are designed to help with:
• Hair fall and breakage linked to hard water and chlorine exposure.
• Dry, itchy, or flaky scalp.
• Dry, tight, or dull-looking skin after bathing.
SF-15 positions these benefits in the context of whole-bathroom water softening. DIVA-05 adds an emphasis on overall shower comfort softer water feel, five spray modes, and a more relaxing bath experience.
Coverage and Use Cases
SF-15: One unit can serve either a shower or a tap (with appropriate connectors). It suits households that want filtered water not only for bathing but also for face washing or other bathroom uses. Combo packs are available for broader coverage.
DIVA-05: Designed for shower use only. Ideal when the shower is your main priority and you want to improve both water quality and spray experience in a single step, without modifying any other bathroom plumbing.
Our Recommendation
If you are deciding between SF-15 and DIVA-05, here is the simplest way to choose:
• Choose SF-15 if you want maximum flexibility, shower and tap coverage, and don’t want to replace your existing shower head
• Choose DIVA-05 if a better shower experience is your priority: built-in spray modes, a modern design, need a water saving product and hard water filtration all in one upgrade.
Both models use the same 15-stage SFC-15 cartridge and are engineered for Indian hard water. You are not choosing between different levels of filtration quality you are choosing the form factor and coverage that best suits your bathroom and lifestyle.
