How It Works
From box to better water in under five minutes.
No plumber, no tools, no guesswork. Here's exactly what happens from the moment your ZEVAREL arrives to your first shower — filtered from start to finish, with Vitamin C when you choose.
The Process
Five steps, start to finish.
- 01
Unbox
The filter body, filter cartridge, and install guide arrive in one package — no extra tools or hardware required.
- 02
Detach your showerhead
Unscrew your current showerhead from the shower arm by hand or with a wrench if it's on tight. Wipe the threads clean.
- 03
Thread ZEVAREL in place
Screw ZEVAREL onto the shower arm, then reattach your existing showerhead on top. Hand-tighten — no plumber, no tape required for most fittings.
- 04
Switch on Vitamin C
Filtered water runs from the moment you turn on the shower. Switch on the Korean-made Vitamin C finish anytime — we recommend the final 2–5 minutes.
- 05
Replace on schedule
Swap the filtration cartridge every 3–6 months and the Vitamin C cartridge every 2–3 months (or when flow noticeably slows). Each replaces independently, without removing the showerhead.

Common Questions
Before you install.
- Do I need a plumber or any tools?
- No. ZEVAREL is designed for tool-free installation on any standard 1/2-inch shower arm — most people finish in under five minutes.
- Will it reduce my water pressure?
- ZEVAREL is engineered to maintain strong, steady flow while filtering continuously. If flow slows noticeably, it usually means the cartridge is due for a swap.
- How often do I replace the cartridge?
- The filtration cartridge lasts about 3–6 months, and the Vitamin C cartridge about 2–3 months, depending on usage and local water quality. Each replaces independently.
- Can I use it without Vitamin C?
- Yes. Filtered water runs the entire shower regardless — switching on the Vitamin C finish is entirely optional, and turning it on never stops filtration.
