No. The Flow System hand-tightens onto your existing shower arm with no tools, no drilling, and no permanent changes. It installs and removes in under 2 minutes and leaves zero trace. Most tenants don't mention it to their landlord at all. When you move, it moves with you.

Yes. The Flow System uses passive filtration — no electricity, no pumps. It works purely on water flow, so load-shedding has zero effect. During low pressure periods, it continues filtering whatever water comes through. Most SA customers notice no change in performance during typical pressure dips.

Yes — usually in the first shower. Most SA customers describe the water feeling "softer" or "silkier" almost immediately. Skin and scalp improvements build over 2–4 weeks of daily use. SA water carries higher chlorine and sediment loads than many other countries — so the shift is often more noticeable here, not less.

No. The Flow System uses a directional flow design that filters without restriction. Most customers say pressure feels unchanged — some say it feels better once sediment clears from the showerhead over the first week.

The dual-stage system reduces chlorine (added by SA municipalities during treatment), sediment, rust particles, and pipe residue — the main causes of dry skin, dull hair, and scalp irritation in SA households. Particularly effective in inland areas like Gauteng where chlorine treatment is typically higher.

Every 2–3 months for most SA households. If your building has older pipes or you're in a high-chlorine area, you may notice a slight pressure drop sooner — that's your cue to replace. Replacement cartridges are R359, and you can subscribe to never think about it.

Yes — and this is often where customers feel the biggest difference. Sensitive skin reacts most to chlorine and mineral exposure. By reducing these at the source, many customers with eczema, rosacea, or persistent dryness report noticeably calmer skin within the first two weeks. For diagnosed conditions, your dermatologist's advice always takes priority.
