Key Takeaways:

• ZeroWater removes nearly all Total Dissolved Solids (TDS), but at a cost. It strips beneficial minerals from water, making it similar to distilled or reverse osmosis (RO) water, which can impact long-term health.
• The short lifespan of ZeroWater’s frequent filter replacements drive up costs, especially in areas with hard water, leading to ongoing expenses of $390–$780 per year.
• The five-stage filtration process significantly reduces flow rate, making it inconvenient for quick access to clean water.
• ZeroWater’s 90-day warranty does not cover common issues that arise after prolonged use, frustrating many customers.
• Unlike ZeroWater, Tyent’s water ionizers remove over 200 contaminants while preserving essential minerals, providing better hydration and long-term value.

Clean drinking water isn’t a luxury—it’s a basic human need. Unfortunately, tap water can contain contaminants like lead, chlorine, and pesticides. A high-quality filtration system can eliminate these harmful substances and enhance water’s quality and taste. 

It’s no surprise that many people turn to water filters to ensure safe hydration. Water pitchers are popular, but effectiveness varies by brand.  ZeroWater claims to remove virtually all dissolved solids from water. But does it live up to its claims? 

Tyent, a leader in water ionization and advanced filtration technology, offers a superior alternative to traditional water filters. With medical-grade filtration that removes over 200 contaminants while preserving essential minerals, Tyent’s water ionizers provide cleaner, healthier hydration.

In this review, we’ll take a deep dive into ZeroWater’s filtration system, analyzing its effectiveness, benefits, drawbacks, and how it compares to better alternatives like Tyent.

What is ZeroWater?

ZeroWater is a water filtration brand known for its five-stage filter system. Unlike standard carbon filters, ZeroWater’s technology is designed to eliminate almost all total dissolved solids (TDS), much like a standard RO water system. Its TDS meter is like an at-home water test, measuring water purity before and after filtration.

The company markets its system as producing “000” TDS water. That means there are no detectable dissolved solids in the water, resulting in a crisp, clean taste. However, this five-stage filtration strips beneficial minerals from the water that are essential for optimal health, and it makes the water slightly acidic. Acidic water can disrupt the body’s pH balance, potentially leading to acidosis, mineral deficiencies, and long-term health concerns. 

ZeroWater Review

ZeroWater’s five-stage filtration system removes TDS from drinking water. The system features a TDS meter to verify water quality, but there’s more to water quality than TDS levels alone.

Products

Source

ZeroWater’s product line focuses on the following basic filtration options:

• Pitcher filters: Standard 6-10 cup countertop pitchers
• Dispenser filters: Larger containers with spigot dispensers
• Faucet filters: Direct tap attachments for continuous filtering
• Replacement filters: Five-stage filters requiring frequent changes

Pros of ZeroWater

Here are some of the benefits ZeroWater offers:

• Reduces TDS to “000”: Eliminates virtually all dissolved solids
• Includes TDS meter: Allows users to check water quality before and after filtration
• National Sanitation Foundation (NSF) certified: Meets basic certification requirements for filtering out contaminants like heavy metals (iron, lead, mercury, etc.) and inorganic non-metals (chlorine, cyanide, fluoride, etc.).
• Simple setup: No professional installation required
• Filter recycling program: Company accepts used filters for recycling

Cons of ZeroWater

ZeroWater’s limitations create ongoing challenges, including:

• Short filter lifespan: Filters require frequent replacements, especially with hard water
• Removes beneficial minerals: Strips calcium, magnesium, and other essential nutrients, making it as unhealthy as distilled water
• Creates slightly acidic water: Lacks mineral balance, affecting overall hydration
• High ongoing costs: Replacement filters cost between $15 and $20, and most users replace them every 2-4 weeks, leading to additional annual expenses of $390–$780
• Limited warranty: Offers only 90 day warranty, failing to cover long-term issues
• Slow filtration speed: Water takes 3-5 minutes to filter completely

ZeroWater Pricing

ZeroWater’s pricing structure includes higher costs compared to basic pitcher filters. A standard ZeroWater pitcher starts at $20, while some of their premium models run up to $50. Large-capacity dispensers range from $40 to $80.

Ongoing costs add to the expense of ZeroWater use—each replacement filter costs $15 to $20, and multi-packs run $30 to $80. The filter’s lifespan depends on your water quality—most users need replacements every 2-4 weeks, resulting in significant annual expenses. 

While ZeroWater offers subscription options for filter replacements, the frequent replacement schedule and limited warranty coverage make the long-term investment considerable. The 90-day warranty period doesn’t protect against common issues that emerge after extended use.

ZeroWater Customer Reviews

Customer feedback about ZeroWater reveals clear patterns. The initial experience often differs from long-term satisfaction rates, and there’s a distinct divide between first impressions and sustained usage. 

Their 90-day warranty doesn’t cover common issues after the first few months, and the replacement costs don’t stop adding up. While ZeroWater filters eliminate TDS, the ongoing expenses and maintenance requirements cause much frustration.
