Sans Water Purifier Overview

No products found.

The Sans Water Purifier is a countertop reverse osmosis system made by Sans Home Wellness, a US based company out of California. It launched to strong consumer interest and has gained attention through social media and expert review sites like Forbes and Water Filter Guru.

This purifier sits on your kitchen counter and requires zero plumbing or installation. You simply plug it into an outlet, fill the back tank with tap water, and the system does the rest. It pushes water through four filtration stages and then dispenses clean water into a glass pitcher.

The four stages include a sediment and carbon pre-filter, an ultrafine reverse osmosis membrane, a VOC carbon filter (with optional remineralization upgrade), and a UV-C light for bacterial protection. Together, these stages target a wide range of contaminants.

Sans positions itself as a premium option in the countertop RO market. The retail price of $499.99 places it at the higher end. Competing models from brands like AquaTru, SimPure, and Bluevua offer similar filtration at lower price points.

The purifier features a SmartPure TDS display on top that shows the total dissolved solids in your water in real time. This gives you instant feedback on water quality. It also includes a filter replacement indicator so you never have to guess when to change your filters.

Filtration Technology and How It Works

The Sans Water Purifier relies on reverse osmosis (RO) as its core filtration method. RO forces water through a semipermeable membrane with pores as small as 0.0001 microns. This membrane blocks dissolved solids, heavy metals, chemicals, and other impurities.

Before water reaches the RO membrane, it passes through a sediment and carbon pre-filter. This first stage catches larger particles like sand, rust, and chlorine. Removing chlorine at this stage is important because chlorine can damage the delicate RO membrane over time.

After the RO stage, water moves through a VOC (volatile organic compound) carbon filter. RO membranes typically do not remove VOCs well, so this extra carbon stage fills that gap. You can upgrade this filter to a remineralization version for an additional $20. The remin filter adds back small amounts of minerals and raises the water’s pH.

The final layer is UV-C light sterilization. This UV function runs automatically to prevent bacteria from growing inside the internal water tank. Sans markets this as a purification stage, though experts note it is more of a maintenance feature than a true filtration step.

The entire process takes about 10 minutes to fill the glass pitcher with roughly 57 ounces of purified water. The system operates with a reported 3:1 pure to wastewater ratio, meaning it wastes less water than many older RO systems.

Contaminant Removal Performance

This is where the Sans Water Purifier truly matters. Independent lab testing has provided clear data on what this system removes from tap water.

Water Filter Guru sent pre and post filtration samples to SimpleLab for Tap Score analysis. The results showed 100% removal of fluoride, uranium, copper, nitrate, phosphorus, zinc, molybdenum, and manganese. These are significant results, especially for fluoride and uranium, which exceeded health guideline levels in the test water.

The system also reduced sulfate by 80%, barium by 96%, and strontium by 85%. Chlorine was completely eliminated at 100% removal. These numbers confirm the Sans purifier works well against a broad range of health related and aesthetic contaminants.

However, some context is needed. Other countertop RO systems have scored even higher in similar testing, with certain models achieving complete removal of every single detected contaminant. The Sans purifier left trace amounts of some minerals behind, though this may partly be due to the remineralization filter adding minerals back.

The SGS test report from Sans claims over 99% reduction of lead, arsenic, chromium, and PFOA/PFOS. These contaminants were not present in the specific test water used by Water Filter Guru, so independent verification of those claims is limited.

Overall, the contaminant removal is strong but not best in class. For most households, these results will mean clean, safe drinking water every day.

Top 3 Alternatives for Sans Water Purifier

If you are considering the Sans Water Purifier but want to explore other options, here are three strong alternatives worth checking out.

The AquaTru Carafe (B0BT4FYHFJ) is a top pick among experts. It uses a certified 4 stage reverse osmosis system and collects water directly into a glass carafe with no internal plastic tank. It costs over $100 less than the Sans and holds official IAPMO certification to NSF/ANSI standards. In lab testing, it eliminated 100% of all detected contaminants.

The SimPure Y7P-BW (B0BHZSJHWG) offers a 5 stage RO filtration system with UV-C light at a much lower price point. It holds NSF/ANSI 58 certification, which the Sans lacks. This makes it a certified and budget friendly option for families who want proven contaminant reduction.

The Bluevua RO100ROPOT-UV (B0CNPMRFXS) provides 6 stage filtration including UV and remineralization. It has earned strong reviews on Amazon with over 2,000 purchases per month. The system is compact, portable, and includes a glass carafe for clean water collection.

Design and Build Quality

The Sans Water Purifier has a modern, minimalist design that looks good on most kitchen counters. The unit measures approximately 17 inches wide, 7 inches deep, and 12 inches tall. It does not take up excessive counter space.

The external build uses sturdy plastic construction that feels durable and well made. The glass collection pitcher is a highlight. It holds about 57 ounces and sits at the front of the unit for easy access. Pouring from the pitcher is smooth and drip free.

On top of the unit sits the SmartPure digital display. This screen shows your water’s TDS reading in real time. It also displays filter life status so you can track when replacements are due. The display is bright, easy to read, and adds a premium feel to the overall design.

However, there is a notable design compromise. Inside the unit sits an internal storage tank made from polypropylene plastic. Water first collects in this tank before automatically dispensing into the glass pitcher. Sans does not prominently mention this detail on their product page.

The rear water tank where you pour tap water has hook clips that sometimes make reseating the tank frustrating. This is a minor issue, but it could have been fixed with better engineering during product development.

Smart TDS Display and Water Quality Monitoring

One feature that sets the Sans Water Purifier apart is its built in TDS sensor and digital display. TDS stands for Total Dissolved Solids. It measures the concentration of dissolved substances in your water, including minerals, salts, and metals.

The SmartPure display sits on the top panel of the unit. It shows the TDS reading of your purified water in real time as the system filters. A lower TDS number generally means fewer dissolved solids in the water.

For reference, tap water typically has a TDS between 100 and 400 ppm. The Sans purifier brings this number down dramatically. Users commonly report purified water TDS readings between 10 and 30 ppm, depending on the quality of their source water.

The display also tracks filter life for each of the three filter cartridges. A percentage indicator shows how much capacity remains. This removes the guesswork from filter replacement schedules.

It is worth noting that TDS alone does not tell you everything about water safety. A low TDS number does not guarantee the absence of specific harmful contaminants like PFAS or bacteria. Still, the real time monitoring is a useful feature that adds transparency and confidence in the purification process.

Setup and Installation Process

Setting up the Sans Water Purifier is one of its biggest strengths. This system requires absolutely no plumbing, drilling, or professional installation. You unbox it, place it on your counter, and plug it in.

The unit arrives with all three filters pre-installed. You do not need tools or technical knowledge to get started. The user manual guides you through a simple initial flushing process that prepares the filters for daily use.

This flushing process takes about 36 minutes total. You run four batches of water through the system and discard them. This clears any residual filter material and primes the membranes for proper operation.

After the initial flush, the system is ready for daily use. Fill the back tank with tap water, press the button, and the purifier handles everything automatically. It filters the water, stores it in the internal tank, and then dispenses it into the glass pitcher.

The entire setup experience earned a perfect 10 out of 10 score from Water Filter Guru. Compared to under sink RO systems that require hours of installation and plumbing modifications, the Sans setup is quick and stress free. This plug and play design makes it ideal for renters, apartment dwellers, and anyone who wants clean water without a permanent fixture.

Instant Hot Water Feature

The Sans Water Purifier includes an instant hot water dispensing function. This lets you get heated purified water directly from the unit without boiling a kettle or using a separate appliance.

Sans advertises that the hot water reaches 201°F. However, independent testing found the actual water temperature measured closer to 194°F at the outlet. By the time the water landed in a mug, the temperature dropped to around 160°F. This is still hot enough for tea, coffee, instant oatmeal, and soups.

The hot water feature uses a separate button and spout to prevent accidental burns. You press and hold the hot water button to dispense. This safety lock mechanism is a thoughtful addition, especially in homes with children.

While the hot water function is convenient, it is not a primary reason to buy this purifier. Several competing models do not offer this feature, but they cost significantly less. If instant hot water is a must have for your household, the Sans delivers. Otherwise, a standard electric kettle paired with a cheaper RO system may give you better overall value.

Filter Replacement and Maintenance Costs

Owning any RO system means ongoing filter costs. The Sans Water Purifier uses three replaceable filter cartridges with different lifespans and prices.

The Pre-Carbon Filter costs $34.99 and lasts 12 months or 600 gallons. The VOC Carbon Filter (or remineralization version) also costs $34.99 with the same 12 month lifespan. The RO Membrane costs $54.99 and lasts 24 months or 1,200 gallons.

This breaks down to an annual replacement cost of roughly $125. On a per gallon basis, you are paying about $0.14 per gallon of purified water. This is about average for countertop RO systems. Some competitors cost slightly less per gallon, while others cost more.

Filter replacement is simple. Each cartridge uses a twist and lock design. You pull out the old filter and twist in the new one. No tools are needed. The smart display tells you when each filter needs replacing, so you never run the system with expired filters.

Beyond filter changes, regular cleaning of the glass pitcher and tap water tank is recommended. A soft cloth with mild soap works well. The UV-C light function helps reduce bacteria buildup inside the internal storage tank, which cuts down on how often you need to deep clean.

Warranty and Customer Support

Sans offers a 3 year warranty on the Water Purifier. This is three times the industry average of 1 year for countertop RO systems. The warranty covers defects in materials and workmanship. If your unit fails within the warranty period, Sans will replace it at no cost.

Multiple user reviews confirm that Sans has honored warranty claims and issued refunds for defective units. This is reassuring for a product in the $500 price range.

However, the customer support experience has mixed reviews. Water Filter Guru reported that customer service reps lacked industry knowledge. One support agent incorrectly stated the internal tank was made from “BPA plastic” before being corrected. This kind of misinformation can erode buyer trust.

All orders ship from California with free shipping and no minimum order requirement. Delivery times vary, though some users have reported longer than expected wait times. One reviewer noted a 6 to 8 day shipping window after ordering.

The 30 day return policy allows you to try the system and send it back if unsatisfied. You must keep the original packaging, ensure the unit is in like new condition, and contact Sans before shipping it back. Returning without prior authorization will void your refund eligibility.

Sans Water Purifier vs AquaTru Carafe

The AquaTru Carafe is one of the most common alternatives buyers compare against the Sans. Both are countertop RO systems with glass collection pitchers. But there are key differences.

The AquaTru Carafe costs over $100 less than the Sans Water Purifier. It uses a 4 stage ultra reverse osmosis system and is IAPMO certified to NSF/ANSI standards. The Sans has no official certification. This alone is a significant advantage for the AquaTru.

In lab testing, the AquaTru Carafe removed 100% of all detected contaminants. The Sans removed most contaminants but left trace amounts of a few. Both systems produce excellent water quality, but the AquaTru performed slightly better across the board.

A major design difference is the internal water tank. The AquaTru Carafe dispenses purified water directly into its glass carafe with no intermediary plastic storage. The Sans stores water in a polypropylene tank first. For buyers concerned about plastic contact with purified water, this matters.

The Sans does offer two features the AquaTru lacks: instant hot water dispensing and a real time TDS display. If those features are important to you, the Sans may justify its higher price. Otherwise, the AquaTru Carafe delivers better value and verified performance.

Pros and Cons of the Sans Water Purifier

Every product has strengths and weaknesses. Here is a balanced look at the Sans Water Purifier based on expert testing and real user feedback.

Strong contaminant removal is the biggest selling point. Lab results show it eliminates fluoride, uranium, chlorine, copper, and many other harmful substances. The 4 stage RO with UV-C provides a thorough purification process that delivers clean tasting water.

The plug and play setup makes it accessible to anyone. No tools. No plumbing. Just unbox, plug in, flush, and start drinking pure water. The smart TDS display is a nice bonus that gives you confidence in your water quality at a glance.

The 3 year warranty and free shipping show that Sans stands behind their product. The instant hot water feature adds convenience for tea and coffee lovers.

On the downside, the $499 price tag is steep for a countertop RO system. Certified alternatives exist for $100 to $150 less. The lack of NSF/ANSI certification is a legitimate concern. Third party testing is good, but official certification provides a higher level of accountability.

The internal plastic storage tank contradicts the premium glass pitcher marketing. Customer service quality also needs improvement. The slow filtration rate of 0.046 GPM makes this one of the slower countertop RO models on the market.

Who Should Buy the Sans Water Purifier

The Sans Water Purifier works best for specific types of buyers. It is not the right fit for everyone, but it excels in certain situations.

This purifier is ideal for people who want a countertop RO system with a modern design and minimal setup. If you rent your home and cannot install an under sink system, the Sans is a strong choice. Its plug and play design means you can take it with you when you move.

Families concerned about PFAS, microplastics, and heavy metals in their tap water will benefit from the strong contaminant removal. The system’s ability to eliminate fluoride and uranium makes it especially useful in areas with known water quality issues.

If you value the instant hot water feature and real time TDS monitoring, the Sans offers both in a single unit. These features are not common in all countertop RO systems.

However, if you are on a tight budget, better certified options exist for less money. If you want the absolute best lab tested performance, the AquaTru Carafe has outperformed the Sans in independent testing. And if you need high flow rates for a large household, a traditional under sink RO system will serve you better.
