Puretec CR20 Caravan & RV Inline Water Filter
Not every tap at a caravan park or bore tastes the way you'd want it to. The CR20 sits inline while filling the tank, and does the one job it's built for without adding any plumbing to the van itself.
Key features
- SilverPlus antibacterial carbon filtration
- 1 micron filter rating
- 20 litres per minute flow rate
- Standard 1/2" garden hose fittings
- Operating range of 2-38°C
- Reduces sediment, rust, chlorine, taste, odour and organic chemicals
RV use case
This suits owners filling the onboard tank from a mix of known and unknown water sources — caravan park taps, shared bore water, or remote fill points — who want cleaner-tasting water without installing a whole-of-van filtration system.
Pros
- 20LPM flow rate doesn't noticeably slow down filling the tank
- Simple garden-hose fitting needs no plumbing changes
- Antibacterial filter media inhibits growth inside the filter between uses
Cons
- Not a substitute for proper water purification — it's a taste, odour and sediment filter, not a biological safety barrier on its own
- Cartridge needs periodic replacement to keep performing
- Inline only, so it doesn't do anything for water already sitting in the tank
Best for
Owners regularly filling up from a mix of trusted and untrusted taps who want better-tasting water without a bigger filtration install.
Verdict
A cheap, simple upgrade that does exactly the one job it's designed for — just don't mistake it for full water purification.
