The result is powerful contaminant reduction, improved taste, and confidence in every glass.
The HealthShield™ Reverse Osmosis system features a powerful two-filter design that combines Aquasana's Claryum filtration technology with high-performance reverse osmosis membrane. Together, they target dissolved solids, microscopic impurities, and a broad range of contaminants that can affect the taste, odor, and quality of your drinking water.
Maintaining peak filtration performance is simple with HealthShield™ Reverse Osmosis. Front-facing smart indicator lights continuously monitor filter life and clearly alert you when it's time for a replacement, eliminating the guesswork. The system also helps maintain more consistent water quality after periods of non-use with an automatic membrane flush that clears away dissolved solids that could otherwise build up while the system is idle. For added protection, built-in leak detection continuously monitors for water inside the system. If water is detected, the system automatically shuts down, then provides flashing indicator light and an audible alarm to help prevent further leakage.
Whether you're filling a glass, brewing coffee, cooking meals, or washing produce, HealthShield™ Reverse Osmosis provides filtered water for everyday use. Designed for modern kitchens, the system delivers reliable water flow, tool-free filter replacements, and certified contaminant reduction in a compact under sink reverse osmosis system.

How to Install Aquasana's HealthShield™ Reverse Osmosis Water Filter
HealthShield™ Reverse Osmosis Under Sink System
Need a replacement filter?
Water filters are an effective way to provide your household with healthy, great-tasting water. However, waiting too long to replace your filter can cause your system to stop working, and it may even become a source of bacteria or mold. Prevent filter contamination by replacing it on time.
Get filters auto-delivered right when you need them — plus receive 15% off the price of replacement filters, free shipping, and an extended limited warranty on your filtration system. Protect your investment and save money with our no-contract Water for Life® program.
It depends on your local plumbing code. Some plumbing codes require a reverse osmosis (RO) system to be installed with either an air gap faucet or a backflow prevention device on the drain connection. These components help prevent drain water from flowing back into the drinking water system and are intended to support health and safety requirements.
Before installation, check your local plumbing codes or consult a licensed plumber to determine which option is required in your area. HealthShield™ RO systems can be installed with a compliant air gap faucet or an approved backflow prevention solution, as allowed by local code.
Stage 1 (Claryum® Filter) filter cartridges should be replaced every 6 months or up to 320 gallons. Stage 2 (RO Membrane) should be replaced every 12 months depending on usage and water quality. For homes with higher water usage and/or poorer water quality, you may need to replace your RO Membrane sooner than every 12 months.
To eliminate the hassle of knowing when to replace your filter, sign up for our Water for Life auto-ship program. Get free shipping, discounts on filter replacements, and an extended product warranty by joining Water for Life®.
Reverse osmosis is an incredibly effective method of filtering water, and it works by pushing water through a semi-permeable membrane (a porous block) at a high pressure to remove contaminants. As this pressurized water passes through the membrane, contaminants are left behind and only clean water passes through.
Our reverse osmosis system uses a multi-stage filtration process for comprehensive water treatment. First, a built-in pre-filter reduces chlorine and sediment. Next, the RO membrane targets dissolved solids and microscopic contaminants. Finally, an Aquasana Claryum® post-filter enhances taste and odor while providing additional contaminant reduction before the water reaches your dedicated faucet.
TDS creep is a common occurrence in reverse osmosis systems where the first water produced after a period of non-use may contain a higher concentration of dissolved solids than water produced during normal operation. When an RO system is idle, pressure across the membrane equalizes and dissolved ions can slowly move into the purified water resting next to the membrane.
HealthShield™ Reverse Osmosis helps address this with an automatic flush feature. After the system finishes producing water, it flushes water through the membrane to help remove dissolved solids that could otherwise build up during idle periods. This helps keep the membrane cleaner and supports more consistent water quality from the first glass.
Cloudy water is completely normal after a new installation or filter change. In most cases, it's caused by tiny air bubbles released from the carbon filter. Activated carbon naturally holds oxygen from the manufacturing process, and when water first flows through the system, that air is released into your water.
You may also notice some air in the system right after installation. Running water through the filter during the initial flush — and over the next few uses — helps push this air out. As the system continues to run and sit between uses, the cloudiness will gradually disappear.
This cloudiness is harmless and does not affect water quality. Your water is safe to drink and will clear up on its own with regular use.
Yes. The HealthShield™ RO includes a pre-filter designed to help protect the system from sediment, such as sand, silt, rust, and other particles found in some water supplies. This added layer of protection helps maintain system performance and can extend the life of the RO membrane.
Signs of elevated sediment may include cloudy or gritty water, visible particles, reduced water pressure, or filters that need to be replaced more frequently than expected. If you’re unsure, fill a clear glass with water and let it sit undisturbed. Particles that settle at the bottom may indicate sediment in your water.
Homes with higher sediment levels may require more frequent replacement of the Stage 1 Claryum® filter to help keep the system performing at its best.
