The 3-Filter TriGuard System includes the same parts, plus FILTER 3: BioChemGuard and its corresponding White Housing.
The only additional items you need in order to install the system are an adjustable wrench and a drill with a Phillips-head drill tip.
How does the Sentry Wellness System work?
The Sentry Wellness System is an in-line water treatment system designed to work with cold tap water. In the installation video, you will see that our system goes between the cold-water valve and the cold-water line so that when the faucet handle is turned 100% to the cold side, the water will pass through our treatment system before coming out of the faucet.
When the cold water goes through the Sentry Wellness System, it experiences multiple stages of treatment that removes harmful toxins from the water and enriches it with good-for-you minerals. Through this treatment process, you get healthy, clean, great-tasting drinking water straight from your tap!

What toxins does Sentry Wellness System remove?
The Sentry Wellness System removes harmful toxins like ammonia, lead, fluoride, cyanide, copper, chlorine, chromium, arsenic, sulfates, pesticides, bacteria, PFAS, PFOS, and Pharmaceutical VOCs. In addition to removing harmful toxins, our system also enriches the water with essential nutrients like calcium, magnesium, oxygenation, and increased pH for on-demand alkalinity.
Learn more about the benefits of the filtration media we use here.
Is there data to back up your claims?
Yes! Water treated by the Sentry Wellness System has been independent lab tested by several different labs, proving its efficacy. The filtration media used in our system has also been extensively researched and proven effective.
What's the difference between the DualGuard System and the TriGuard System?
The Sentry Wellness System is available in two versions, and the best one for you depends on your water source and quality.
DualGuard System:
- 2-Housing System with ToxyGuard & AlkaGuard Filters.
- Offers comprehensive removal of common water contaminants.
- Recommended for pre-treated water sources, such as residential homes with city-supplied water.
TriGuard System:
- 3-Housing System with ToxyGuard, AlkaGuard, & BioChemGuard Filters.
- Additional filter provides targeted removal of biological & chemical contaminants, including bacteria, pathogen-based viruses & PFOS/PFOAS.
- Recommended for water sources with higher than average levels of contamination, such as: areas with flooding, still water or natural disasters, areas that utilize well water, and areas with higher than average PFAS/PFOAS.
What's the difference between the Sentry Wellness System and an RO System?
Simply put, the Sentry Wellness System removes all the bad stuff and replaces it with the good stuff so you have clean, healthy, great-tasting water.
Reverse Osmosis is a purification process that uses multiple carbon blocks and a semi-permeable membrane to filter out contaminants and sediments. While this process is effective at purifying water, it also strips the water of good stuff like minerals. Reverse Osmosis systems also tend to take up quite a bit of space, which isn’t ideal for under-sink systems.
The Sentry Wellness System uses multiple stages to filter your water that not only removes harmful toxins and neutralizes soft and hard scale, but also enriches the water by boosting alkalinity, oxygenation, calcium, and magnesium. The Sentry Wellness System is also smaller than your standard RO system, so you can still use your under-sink space for other purposes.
Does the Sentry Wellness System work with a traditional salt-based water softener?
The Sentry Wellness System can only be used with a salt-based water softener if it's used to remineralize the water after it passes through a Reverse Osmosis (RO) system. Salts, depending on the dosing amount, can clog our filters and decrease their lifespan. In some cases, the salts may not be removed entirely and leave the water tasting bitter.
In general, we do not recommend using the Sentry Wellness System without an RO system when a salt water softener is in place.
How does the Sentry Wellness System treat recycled water?
The Sentry Wellness System utilizes several types of filtration media, formulated to filter out hard-to-remove organic pollutants found in recycled water, including PFAS, PFOS, and Pharmaceutical VOCs.

Do you offer a leak detection sensor for the Sentry Wellness System?
Yes! Our optional Peace of Mind Shut-Off Valve detects leaks instantly so you can stop leaks before they become a problem. Designed to work with the Sentry Wellness System, this add-on sensor automatically shuts off your water supply and alerts you if a leak is detected.
Why does the Sentry Wellness System look different now?
Sentry H2O recently made some updates to our product design to enhance our customers’ experience.
In November 2024, we updated the Sentry Wellness System with a new and improved housing design to make installation and filter replacements even easier than before.
In July 2025, we updated the filter names across all Sentry H2O product lines. Now less technical and more practical, the new filter names make each filter easier to identify and understand.
Don't worry—the filtration technology and the filters themselves haven't changed!
What should I do if I have the original, clear Sentry Wellness System?
If you have an original system, you don't need to do anything! As long as it was installed properly and is being maintained properly, it will continue to work effectively.
The filters have not changed (just the names!), so the Replacement Filters work in both the original system and the new, 2-Filter DualGuard System.
I just installed my system, why is my water pressure so low?
You may notice a slight decrease in water pressure right after installing your water treatment system. As your system normalizes, excess air is pushed out, which temporarily decreases your water pressure. This should resolve within a few days of use and your water pressure will go back to normal.
If you're experiencing significantly reduced water pressure, it's possible the excess filtration media dust is clogging the filters. To fix this, simply flush the filters by turning on the faucet and then switch back and forth between hot and cold for up to 5 minutes.

How does the Sentry Whole House Wellness System work?
The Sentry Whole House Wellness System is an in-line water treatment system designed to work with residential homes.
With our system, all the water that enters your home first filters through our treatment system, which utilizes our ToxyGuard filtration media blend to remove harmful toxins, neutralize soft and hard scale, and soften water without salt with our salt-free medias.
From doing dishes to morning showers and loads of laundry, this treatment process ensures that the water you use every day is free from irritating toxins.
What’s the difference between the Whole House System for City Water and the Whole House System for Well Water?
The Sentry Whole House System is designed to work for residential homes that use municipal water as their water supply. City water is typically pre-treated by the city to remove some common groundwater contaminants. Our system is designed to fill in the gaps by filtering out the contaminants that are still present after the city's pre-treatment process.
The Sentry Well Whole House system is specialized for residential homes that rely on well water for their water supply. Well water doesn't receive the same water treatment services as public water systems, so it requires additional filtration power to target common well water contaminants. Based on the specific contaminants in your well water, this system can be customized to remove iron, manganese, arsenic, uranium, and/or nitrates.
Why do I need to perform a water quality test prior to purchasing a Whole House System for Well Water?
The Sentry Whole House System for Well Water is designed to remove contaminants that are commonly found in well water sources. However, since every well has different contaminants, each well needs its own custom water treatment formula.
Sentry H2O requires a well water test to be performed and submitted in order to ensure the water treatment formula created for you works for your specific well.
Failure to do so may lead to ineffective water treatment and will void your warranty.
What toxins does Sentry Whole House Wellness System remove?
The Sentry Whole House System for City Water utilizes our ToxyGuard filtration media blend to remove ammonia, fluoride, chlorine, chloramines, arsenic, boron, hydrogen sulfide, phosphorus, sulfates, phosphates, PFAS, PFOS, and Pharmaceutical VOCs.
The Sentry Whole House System for Well Water utilizes our WellGuard filtration media blend to target contaminants commonly found in well water in combination with custom formulations targeting your well’s specific toxins, such as nitrates, iron, manganese, arsenic, and uranium.
Learn more about the benefits of the filtration media we use here.
Is there data to back up your claims?
Yes! TheToxyGuard filtration media blend used in the Sentry Whole House System for City Water and the WellGuard filtration media blend used in the Well System havebeen extensively researched and proven effective.
Is my water ready to use immediately after installation?
Yes! Once the Whole House System is fully flushed at the end of the installation process and the water runs clear, then it's ready to use!
Occasionally, due to shipping, you may experience additional filtration media dust come through your system after the start-up process. This should only occur for an additional 2-3 days as the system normalizes.
What kind of maintenance does your Whole House System require?
Fortunately, maintaining your Whole House System is easy!
First, set a reminder to refresh your Whole House System in the future. To
ensure optimal filtration and water treatment, simply refresh your tank using our Whole Home Revitalizer after 7 years (for 1-3 occupants) or 5 years (for 4+ occupants).
Then, familiarize yourself with the Regeneration Timer on the Whole House Tank, which controls the regeneration process. Just like a regular clock, the Regeneration Clock needs to be reset to the current time after losing power.
That’s it for maintaining your Whole House System! For the included under-sink Wellness System, be sure to replace those filters once per year.
What can I expect for the regeneration process and how much water is used?
The regeneration process simply regenerates the filtration media with water for long-term use.
During the regeneration process for the City System, the Regeneration Head (located at the top of the system) pumps on average for 16 minutes, up to 4-5 gallons per minute, every 4 days. The following is the sequence one can expect to take place: C1 (Backwash/10 minutes); C4 (Rinse/6 minutes). On average an additional $5/month can be expected to be added to your monthly water bill for this process.
During the regeneration process for the Well System, the Regeneration Head (located at the top of Tank 1) will pump on average for 35 minutes, up to 4 gallons per minute, every 2 days. The following is the sequence one can expect to take place: C1 (Backwash/30 minutes); C4 (Rinse/5 minutes).The regeneration process simply regenerates the filtration media with water for long-term use.
Be sure to follow plumbing codes.
My Whole House System is still pumping out water from the regeneration process and it’s been more than 15 minutes. What can I do?
This is very rare and only likely to occur during a regeneration period combined with a loss of power.
Contact us right away so we can help.
To avoid loss of water pressure and possible concerns with the backwashing process, unplug the power to the tank and place the system in bypass by turning the red handled valves perpendicular to the water flow.
Reach out to us by phone at 1-833-377-3817 or by email at CleanWater@SentryH2O.com for next steps.
What do I do when my Whole House System reaches capacity?
To ensure optimal filtration and water treatment, it’s important to refresh your Whole House System using our Whole Home Revitalizer after 7 years (for 1-3 occupants) or 5 years (for 4+ occupants).
When that time comes, simply order your Whole Home Revitalizer from our website (coming Winter 2025!)
