Nobody wants nitrates in their water—especially since they can sneak in from farm runoff, industrial waste, or even natural sources. High nitrate levels are especially risky for babies and pregnant women. Our nitrate resin acts like a smart trap, swapping those harmful nitrates for safer chloride ions (the natural, harmless form of chlorine found in water, salt, and even your body. Chloride ions won’t make water taste or smell weird).

Unlike basic filters that might let nitrates slip back into your water, this special resin holds onto them tightly—even in low-mineral water—so you get cleaner, better-tasting water every time. Plus, it’s eco-friendly and certified safe for drinking.

Want extra protection? Pair it with our ceramic spheres—tiny but mighty filters that also grab nitrates, along with nasty stuff like lead, pesticides, and sulfates. They even balance your water’s PH and add helpful minerals! Easy to drop into your existing filter, these durable little power-ups make water safety simple for homes or large systems.

Nitrate Resin
alumina
Nitrate resin provides an effective solution for removing dangerous nitrates from water caused by agricultural runoff, industrial waste, or natural deposits. Using specialized ion exchange technology, it selectively traps nitrate molecules while releasing safer chloride ions—preventing the "nitrate dumping" issue common with standard resins.

These nitrate-selective resins maintain high performance even in low-TDS water to help  ensure safer drinking water compliance. By reliably filtering out nitrates without harsh chemicals, this eco-friendly solution helps protect against health risks while delivering cleaner, better-tasting water.
Improved Ion Exchange Ceramic Spheres
fluoride
These special ceramic balls work like tiny water purifiers, pulling out the bad stuff and leaving the good behind. They remove dangerous metals like lead and mercury, and filter out nitrates, sulfates, and even pesticides. But they don't stop there - they can actually improve your water by balancing PH levels and releasing beneficial minerals.

What makes them really useful is how easily they fit into existing water filters, working alongside other systems to provide cleaner, safer water without any extra hassle. Tough and long-lasting, these ceramic spheres offer a simple way to upgrade your water quality at home or in larger filtration systems.

How long should your MEER Water Filter last?
How much water do you consume? What impurity concentration do you have? And so many other considered variables... We cannot give you an absolute answer because water profiles vary between zip codes, seasons and from year-to-year. If you were to compare our filters with another comparable size & structure, you will find our water filters realistically last 2-3 times longer because of our premium filtration media. This equates to years and thousands of gallons cleaned. 


We are probably the only brand in the water filtration arena that does not use disclaimers to obscure or exaggerate our filtration abilities.
