10 Best Water Filters Removing Hormones

Last Updated on September 27, 2026 by Logan Reeves

The best water filters for removing hormones should do more than lower total dissolved solids (TDS). Look for published testing for specific compounds, such as estrone, estradiol, and other endocrine-disrupting chemicals.

The Clearly Filtered Water Pitcher has published laboratory data for several hormones. The AquaTru Glass Carafe Smart Alkaline is another option with published testing for estrone.

We also compare under-sink and countertop reverse osmosis systems for readers who want broader filtration. Product specifications, manufacturer documentation, and contaminant-specific performance claims informed this guide. We did not conduct independent laboratory testing.

Water Filters for Removing Hormones: Our Top Picks

Detailed Water Filter Reviews

1. SimPure T1-100 Reverse Osmosis Water Filter System

Bottom line: The SimPure T1-100 is a seven-stage under-sink RO system with a booster pump. It suits households that want a permanent drinking-water system rather than a countertop appliance.

• Filtration: Seven stages, including reverse osmosis.
• Production: 100 gallons per day under rated conditions.
• Storage: 2.5-gallon tank, reducing the need to wait for each glass.
• Installation: Under-sink plumbing and electrical power.
• Maintenance: Replace cartridges according to the manufacturer’s schedule.

SimPure designed this model to reduce a broad range of water contaminants, including dissolved solids and several common chemical pollutants. Its booster pump helps the membrane operate where supply pressure would otherwise limit performance.

The included tank stores filtered water for convenient dispensing. Quick-change cartridges make routine maintenance easier than traditional housings that require opening with a wrench.

However, the manufacturer’s general contaminant-reduction claims should not be treated as proof that this exact configuration removes every hormone. Request results for the specific compounds that concern you.

2. APEC Water ROES-PH75X

Bottom line: The APEC Water ROES-PH75X combines six-stage reverse osmosis with a calcium-based remineralization stage. The linked package also includes extra prefilters.

• Filtration: Six stages, including reverse osmosis and remineralization.
• Production: 75 gallons per day under rated conditions.
• Storage: Four-gallon nominal tank.
• Installation: Under-sink system with a dedicated faucet.
• Maintenance: Includes additional replacement prefilters.

APEC’s reverse osmosis membrane reduces a range of dissolved contaminants. The final mineral stage adds calcium to improve the taste of the finished water.

This package is useful if you prefer traditional under-sink filtration and want extra prefilters included. Remember that a six-stage system is not automatically more effective against hormones than another filter with fewer stages.

The exact certification and performance claims must be checked against the ROES-PH75X documentation. A general RO certification does not establish reduction of every pharmaceutical or endocrine-disrupting compound.

3. Express Water ROALKUV10M

Bottom line: The Express Water ROALKUV10M combines reverse osmosis, UV treatment and mineralization. It suits households wanting these functions in one under-sink system.

• Filtration: Multi-stage RO with UV and mineralization.
• Production: Rated production depends on the installed membrane.
• Storage: Pressurized water-storage tank.
• Installation: Under-sink plumbing and electrical power.
• Maintenance: Filter and UV components require scheduled replacement.

The RO membrane provides the main barrier for dissolved contaminants. Carbon stages help address selected organic compounds, while the mineralization stage changes the taste of the finished water.

The UV stage serves a different purpose. It is designed for microorganisms and should not be counted as proof of hormone removal. Its effectiveness also depends on proper operation and maintenance.

Check the exact package, membrane rating and replacement schedule before buying. You will need enough space for the filter assembly, tank and UV components.

4. VonWater CT910

Bottom line: The VonWater CT910 offers countertop RO filtration with a removable water pitcher. It avoids permanent plumbing modifications.

• Filtration: Seven-stage RO system.
• Production: 100 GPD rated output.
• Capacity: 528-gallon stated filter service capacity.
• Installation: Countertop; requires electrical power.
• Display: TDS and filter-life information.

The removable pitcher lets you carry filtered water to the dining table or refrigerator. The system also offers selectable dispensing volumes.

Its display helps you track dissolved-solids readings and filter replacement. However, the TDS value cannot tell you whether estrone, estradiol or another dissolved organic compound has been removed.

VonWater publishes a rated filter capacity and operating specifications. Confirm that your tap water meets the manufacturer’s feed-water requirements before using it.

5. VonWater CT910GH

Bottom line: The VonWater CT910GH combines countertop RO filtration with instant hot-water dispensing. It is useful when you want filtered drinking water and several temperature settings from one appliance.

• Filtration: Seven-stage reverse osmosis.
• Production: 100 GPD rated output.
• Filter capacity: 528 gallons stated by the manufacturer.
• Temperature: Five selectable settings.
• Installation: Countertop appliance requiring electrical power.

The manufacturer lists temperature settings for room-temperature water and hot beverages. The removable pitcher provides another way to store or serve filtered water.

Its RO membrane performs the main dissolved-contaminant filtration. The heating feature does not provide proof of hormone removal, and the display cannot identify individual chemicals.

Because this model includes a high-power heating function, check its electrical requirements and place it where children cannot accidentally access hot water.

6. Clearly Filtered Water Pitcher

Bottom line: The Clearly Filtered Water Pitcher stands out because the manufacturer publishes separate laboratory results for several hormones and endocrine-disrupting compounds.

• Filtration: Proprietary Affinity filtration media.
• Capacity: 10 cups.
• Filter life: Up to 100 gallons under specified conditions.
• Installation: None; gravity-fed pitcher.
• Materials: BPA- and BPS-free Tritan.

The published performance data report reductions of more than 99.92% for estrone and more than 99.95% for estradiol under the specified laboratory test conditions. Results are also published for estriol, ethinyl estradiol, progesterone and testosterone.

These are contaminant-specific test results, not a guarantee that every hormone in every water source will be removed by the same amount. Filter condition, water chemistry and proper replacement still matter.

The pitcher requires no plumbing or electricity. Its 100-gallon rated filter life means you should track usage rather than relying only on taste or appearance.

Clearly Filtered lists NSF certification to Standards 42 and 372 and provides separate contaminant-reduction testing. Do not confuse those material and taste-related certifications with certification for every published hormone claim.

7. FS-TFC 5-Stage Reverse Osmosis System

Bottom line: The FS-TFC 5-Stage Reverse Osmosis System offers a traditional under-sink layout with sediment, carbon and RO filtration stages.

• Filtration: Five-stage reverse osmosis.
• Production: 100 GPD stated rating.
• Installation: Under-sink plumbing.
• Power: Conventional pressure-driven RO configuration.
• Maintenance: Periodic cartridge and membrane replacement.

This type of system suits households that prefer a dedicated filtered-water faucet. A storage tank provides water between membrane-production cycles.

Its sediment and carbon stages protect the RO membrane and address selected contaminants before water reaches the membrane. Proper prefilter replacement is important for continued performance.

Do not interpret the listing’s broad contaminant-removal percentage as a hormone-specific result. Request the exact model’s performance sheet for the compounds you want reduced.

8. AquaTru Glass Carafe Smart Alkaline

Bottom line: The AquaTru Glass Carafe Smart Alkaline combines four-stage RO filtration, a glass carafe, mineralization and connected monitoring.

• Filtration: Four-stage reverse osmosis.
• Contaminant testing: Published performance data covering 84 contaminants.
• Installation: Countertop; no permanent plumbing.
• Carafe: Removable glass design.
• Monitoring: Connected filter-status features.

AquaTru’s published Carafe performance data include testing under NSF/ANSI 401 for estrone, an estrogen hormone. This makes the supporting evidence more useful for this topic than a general dissolved-solids claim alone.

The alkaline stage adds minerals to the filtered water. Its role is taste and mineralization, not proof that additional hormones have been removed.

The smart features help you follow maintenance needs. You should still use the manufacturer’s filter-life schedule and review the performance sheet for the exact Carafe configuration.

9. Culligan ZeroWater 33-Cup Dispenser

Bottom line: The Culligan ZeroWater 33-Cup Dispenser is an alternative for reducing dissolved solids, not a verified solution for hormone removal. Culligan states that its five-stage filters have not been independently tested for pharmaceutical reduction.

• Filtration: Five-stage filtration with ion-exchange resin.
• Capacity: 33 cups.
• Installation: Freestanding dispenser.
• Monitoring: TDS meter.
• Maintenance: Replace the cartridge according to TDS readings and manufacturer guidance.

The dispenser provides a large supply of filtered water without plumbing or electricity. Its five-stage cartridge combines filtration media and ion exchange to reduce dissolved solids.

However, a low TDS reading measures dissolved ionic content, not the concentration of a particular pharmaceutical or hormone. A reading near zero cannot establish that estrone or another organic compound has been removed.

Choose this dispenser for its documented TDS-related function. For a hormone-specific concern, use a product with relevant compound-specific testing instead.

10. SimPure Y7P-BW

Bottom line: The SimPure Y7P-BW offers five-stage countertop RO with UV treatment. It suits people who want RO filtration without installing a dedicated faucet.

• Filtration: Five-stage RO with UV treatment.
• Production: 100 GPD rated capacity.
• Water efficiency: Manufacturer-stated 4:1 pure-to-drain ratio.
• Installation: No permanent plumbing.
• Dispensing: Selectable 6-, 12- and 15-ounce volumes.

Fill the feed tank, connect the appliance to power and select a dispensing volume. The system includes filter-replacement and low-water reminders.

Its RO membrane and other filtration stages address a range of contaminants. UV treatment serves a separate microbiological function and should not be described as a hormone-removal stage.

The manufacturer publishes test information against NSF/ANSI 58. Check whether a specific certification applies to the complete model and which contaminant-reduction claims are included.

Clearly Filtered vs AquaTru: Which Should You Get?

Both have published testing relevant to hormone reduction. The main difference is the filtration format: Clearly Filtered uses a gravity-fed pitcher, while AquaTru uses powered countertop reverse osmosis.

• Published evidence: Clearly Filtered reports individual results for several hormones. AquaTru publishes NSF/ANSI 401 testing that includes estrone.
• Installation: Neither requires permanent plumbing.
• Power: Clearly Filtered works without electricity; AquaTru requires it.
• Convenience: Clearly Filtered uses a refillable pitcher, while AquaTru adds a powered filtration system and smart features.

Which Water Filter Should You Buy?

How We Chose

• Contaminant-specific evidence: We looked for published results for estrone, estradiol and related compounds rather than relying on general filtration percentages.
• Filtration technology: We compared reverse osmosis, carbon-based filtration and ion-exchange systems.
• Practical fit: We considered installation, capacity, maintenance, electrical requirements and household use.
• Documentation: We checked manufacturer information, product listings and relevant certification guidance.
• Safety: We considered appropriate use, maintenance requirements and product-recall information.

These are research-based comparisons, not results from our own laboratory testing. A product’s published performance should always be checked for the exact model and contaminant.

Factors to Consider When Choosing Water Filters Removing Hormones

Filtration Technology Type

Reverse osmosis uses a semipermeable membrane to separate many dissolved substances from water. Carbon filtration works through adsorption, while ion exchange targets selected dissolved ions.

Each technology has strengths and limitations. A system’s effectiveness depends on the specific contaminant, media, water chemistry and operating conditions.

UV treatment is primarily used for microorganisms. It should not be treated as evidence that a system removes dissolved hormones.

Contaminant Removal Efficiency

Look for test results naming the exact hormone or chemical you want reduced. Estrone, estradiol and ethinyl estradiol are different compounds, and performance against one does not establish performance against all of them.

For example, the Clearly Filtered pitcher publishes separate test results for multiple hormones. This is more informative for a hormone-specific concern than a general claim that a filter removes 99% of contaminants.

A TDS meter cannot measure hormone concentrations. Low TDS may indicate effective removal of dissolved ions, but it does not establish removal of neutral organic molecules.

Certification and Standards

NSF/ANSI 401 addresses selected emerging contaminants, including estrone and several pharmaceutical compounds. Check the individual reduction claims for the exact model.

NSF/ANSI 58 covers reverse osmosis drinking-water systems. NSF/ANSI 53 addresses specific health-related contaminant claims, while NSF/ANSI 42 includes aesthetic claims such as chlorine taste and odor reduction.

Certification to one standard does not mean a product removes every contaminant covered by that standard or every possible hormone.

Use the NSF emerging-contaminants guide to understand what the relevant claims mean.

Maintenance and Replacement

Replace cartridges according to the manufacturer’s instructions. Some pitcher filters are rated by gallons, while RO systems may have different schedules for sediment filters, carbon cartridges and membranes.

Do not rely on taste alone. A filter may continue producing pleasant-tasting water even after its rated treatment capacity has been reached.

For an RO system, monitor membrane performance, check connections and follow the recommended cleaning or sanitizing procedure.

Flow Rate and Capacity

Consider how much drinking and cooking water your household uses. A pitcher may suit one or two people, while a larger household may prefer a countertop RO appliance or an under-sink system with storage.

Gallons per day describes production under specified test conditions. It is not the same as the amount of water immediately available from a dispensing faucet.

For stored-water systems, check both the production rating and the usable storage capacity.

Installation Requirements

Under-sink RO systems generally require a feed-water connection, drain connection and dedicated faucet. Pump-equipped and UV-equipped models also need electrical power.

Countertop systems avoid permanent plumbing but need counter space, electricity and regular feed-tank refilling. Gravity pitchers require no installation.

Measure your available space before ordering. Include clearance for cartridge replacement and reservoir removal.

Water Quality and Testing

Start with your water supplier’s current water-quality report. Private-well users should arrange appropriate testing based on local conditions.

Most household filters are designed for water that is already microbiologically safe. Do not assume a chemical-reduction filter can make untreated or contaminated water safe to drink.

If you have a specific concern about pharmaceuticals or hormones, ask an accredited laboratory which compounds can be tested and what the results mean.

Environmental Impact Considerations

Reusable filtration systems can reduce reliance on bottled water, but they still require cartridges and other replacement components.

Reverse osmosis also produces a concentrate stream. Compare the manufacturer’s pure-to-drain ratio, and check whether that rating applies to your operating conditions.

Follow local disposal instructions for used filters, especially when the source water contains contaminants of concern.

Mistakes to Avoid When Buying Water Filters

• Trusting a blanket percentage: Check results for individual contaminants.
• Confusing TDS with hormone removal: TDS meters do not measure individual organic compounds.
• Assuming UV removes hormones: Verify the RO or other chemical-filtration stages separately.
• Ignoring maintenance: Replace filters before exceeding their rated capacity.
• Buying the wrong variant: Match the model and cartridge configuration to the published performance data.

Frequently Asked Questions

How Often Should I Replace Water Filter Cartridges?

Replace cartridges according to the manufacturer’s stated service life or gallon capacity, whichever limit applies. Different stages may have different schedules. Water quality and usage can shorten filter life. Do not wait until the water tastes bad, because taste cannot reliably indicate whether the filter still reduces the contaminants you care about.

Can Water Filters Remove All Types of Hormones?

No filter should be assumed to remove every type of hormone. Performance depends on the compound, filtration technology and operating conditions. Choose a system with published test results for the specific hormone. For example, estrone testing does not automatically establish identical reduction of estradiol, progesterone or other compounds.

Are Reverse Osmosis Systems Energy Efficient?

Energy use varies by design. Some conventional under-sink RO systems operate using water pressure, while systems with pumps, UV lamps, heating or electronic dispensing require electricity. Reverse osmosis also produces concentrate water. Compare both power requirements and the manufacturer’s pure-to-drain ratio when evaluating operating costs.

Do Water Filters Improve Taste and Odor?

Many filters improve taste and odor by reducing chlorine and selected organic compounds. However, improved taste does not prove that hormones or other contaminants have been removed. A filter designed mainly for taste may have no validated reduction claim for the chemical that concerns you.

What Is the Average Lifespan of a Water Filter?

There is no single lifespan for every filter. Some pitchers use a gallon-based cartridge rating, while reverse osmosis systems have separate service intervals for prefilters and membranes. Check the exact replacement schedule, track usage and follow the manufacturer’s instructions for changing each component.

Does a Zero TDS Reading Mean Water Is Free of Hormones?

No. A TDS meter estimates dissolved ionic content through electrical conductivity. It does not directly measure individual hormones, pharmaceuticals or many other organic compounds. A near-zero reading can be useful for monitoring certain filtration systems, but it cannot replace compound-specific laboratory testing.

What Certification Should I Look for When Removing Hormones?

Look for contaminant-specific performance claims under a relevant standard, especially NSF/ANSI 401 for selected emerging contaminants. The standard includes estrone. Verify the exact model in the certification listing and check which individual compounds are covered. Certification to NSF/ANSI 58 alone does not establish removal of every hormone.

Can Activated Carbon Remove Hormones?

Activated carbon can adsorb certain organic chemicals, including some endocrine-disrupting compounds. Results depend on the carbon media, contact time, water chemistry and individual contaminant. Do not assume an ordinary carbon pitcher removes a particular hormone unless its published performance data support that claim.

Final Verdict

For water filters intended to reduce hormones, prioritize published compound-specific test results over general purification claims. The Clearly Filtered Water Pitcher provides published data for several hormones, while the AquaTru Glass Carafe Smart Alkaline provides a countertop RO option with published estrone testing.

For countertop reverse osmosis, consider the AquaTru Glass Carafe Smart Alkaline. For permanent under-sink RO filtration, consider the SimPure T1-100, while verifying the contaminant-specific claims relevant to your water.
