Why Customers Choose This Product
Product Highlights
Treatment at Two Locations
The whole-house unit treats water at the home's incoming supply, while the separate under-sink system provides an additional treatment location. This lets you plan filtration for everyday household use alongside your drinking-water connection.
Choose Your Under-Sink System
Select the DualGuard two-filter system or the TriGuard three-filter system. Confirm each configuration's filter media, documented performance, and replacement requirements before choosing.
Match Your Connection
Choose 3/8-inch fittings for the under-sink connection or 1/4-inch fittings for the refrigerator connection. The direct RO replacement option lists 1/4-inch fittings, a faucet, and a redirect valve; verify compatibility with your existing installation.
Optional UV Equipment
Select no UV system, a VIQUA VH200 listed at 9 GPM, or a VIQUA VH410 listed at 18 GPM. UV suitability and performance depend on feed-water conditions, installation, maintenance, and the specific manufacturer's requirements.
Maintenance Supplies Included
The described package includes three Whole Home Revitalizer kits. Use them according to the manufacturer's instructions, and confirm the separate servicing needs of the whole-house, under-sink, and any selected UV components.

Important Information
- Review a current water analysis with a qualified water-treatment professional before selecting equipment. Match the system to your water supply, treatment goals, household demand, and installation conditions.
- Specific reductions of PFAS, fluoride, arsenic, chlorine, or other substances should be confirmed through performance documentation for the exact configuration. No universal removal percentage or contaminant-free water guarantee is stated here.

- Have a qualified installer confirm plumbing compatibility, available space, service flow, pressure limits, and any electrical requirements. Follow the manufacturer's instructions and applicable local requirements.
- Optional UV equipment requires appropriate water conditions and maintenance. Do not assume this package makes microbiologically unsafe or untested water safe; obtain professional guidance and verify treated-water quality.
- Replace filters and maintain each component according to its manufacturer's instructions. Service intervals depend on water quality and usage.
- No health benefits, guaranteed mineral levels, fixed alkalinity, or certification claims are made in this description.

Frequently Asked Questions
What is included in the package?
The described package includes the Sentry whole-house system, your selected DualGuard or TriGuard under-sink system, and three Whole Home Revitalizer kits. UV equipment is included only if you select a UV configuration. Connection components depend on the option selected.
What is the difference between DualGuard and TriGuard?
DualGuard is the two-filter under-sink option, and TriGuard is the three-filter option. Confirm the filter media, documented treatment performance, and maintenance requirements of each before choosing.
Which connection options are available?
The options are an under-sink connection with 3/8-inch fittings, a refrigerator connection with 1/4-inch fittings, or a direct RO replacement connection with 1/4-inch fittings, a faucet, and a redirect valve. Have an installer verify compatibility with your plumbing.
Is UV equipment included as standard?
No. Choose no UV system, the VIQUA VH200 listed at 9 GPM, or the VIQUA VH410 listed at 18 GPM. Ask a qualified water-treatment professional to confirm suitability for your water conditions and required flow.
Does this system replace a water softener?
Do not assume it replaces a water softener. Confirm any hardness-treatment capability with the manufacturer and use water-test results to determine whether separate softening equipment is needed.
Choose the under-sink configuration and connection type that fit your home, then confirm the system requirements against your water analysis. With those details in place, this Sentry H2O package offers a coordinated starting point for whole-house and drinking-water filtration.
