Sentry Portable Water Filter System, Standard or Premium

A portable filter station for your next RV hookup. Carry the Sentry Portable System to a compatible water connection, attach the required hoses and filter water through its two-cartridge housing. A handle and hanging hook make it easier to position at your setup.

Choose your filter set

• Standard, $499.99: ToxyGuard and AlkaGuard cartridges. The supplier identifies this set for pretreated or city-supplied water.
• Premium, $549.99: BioChemGuard and AlkaGuard cartridges. Ask us to check the media against your water report and intended use before choosing.

Plan the complete setup

The system uses a connected water source. It is not a water tank, independent pump or power-outage water supply. Two suitable garden hoses are required and are not included. Follow the supplier's installation, flushing, pressure and maintenance instructions before use.

Read Sentry's installation and filter-replacement guides. Match the guide to your exact filter set. Use water suitable for the intended purpose. Do not rely on this product alone to make unknown, untreated or contaminated water safe to drink.

Know the limits before buying

This listing does not promise removal of every contaminant or certify the safety of an unknown water source. Freezing, unsuitable pressure and incorrect installation can damage the system. If you have a private well, a contamination concern or a boil-water notice, check the required treatment with the appropriate local authority before selecting equipment.

Keep the system serviceable

Matching portable replacement-filter sets are sold separately. Sentry recommends annual filter replacement; your water conditions and use may require earlier service. This is a one-time purchase, with no subscription.

Check your fit

Send SPM your water-source type, connection setup and intended use before ordering if you are unsure which set fits.
