Boroux vs. Rorra vs. Culligan: Steel Water Filters Tested

Three new stainless steel water filter systems are vying to take the place of the standard plastic pitcher. A hands-on comparison reveals some key differences in their performance, feel, and durability.

The timing is crucial. Recently, the FBI warned about cyberattacks on water treatment facilities in seven states, as reported by Engadget. While these hacks targeted municipal systems and not directly your home tap, it has prompted many to consider the quality of their faucet water. This concern raises the question: is a home filter worth it?

Enter Boroux, Rorra, and Culligan. These three brands are introducing a new generation of metal-bodied filter systems that aim to improve upon the flimsy plastic jugs that have filled kitchen counters for years. Wired put all three models to the test in real-world conditions to see which one performs best.

Why Choose Steel Over Plastic?

Standard filter pitchers—like those from Brita or PUR—are made from polycarbonate plastic. This material is lightweight and commonly found in food containers. While they do filter water, they scratch easily, can absorb odors over time, and raise concerns about microplastics leaching into your water. Stainless steel pitchers avoid many of these drawbacks. They’re more durable, easier to clean, and don’t retain flavors from previous contents.

Think of it as the difference between a plastic to-go cup and a Stanley tumbler. Both serve the same purpose, but the materials and overall experience are vastly different.

How the Three Systems Stack Up

Boroux

Boroux positions itself as the premium choice. It features a fully stainless steel body and a filter that removes heavy metals, including lead, chlorine, and certain volatile organic compounds (VOCs). The build feels solid, and its sleek design makes it a stylish addition to your counter. However, the downside is cost; replacement filters can get pricey over time.

Rorra

Rorra takes a different route. It combines a stainless exterior with a focus on speed. Its filter flow rate is quicker than its competitors, which is important if you’re constantly filling glasses for your family. Rorra targets the same contaminants as Boroux but comes at a lower price. This makes it a great middle-ground option.

Culligan

Culligan is the most established brand of the three, boasting decades of experience in water treatment. Its stainless pitcher is a newer addition, benefiting from the company’s extensive filtration certifications. This option is ideal for buyers who prioritize verified performance over design trends.

What This Means for Users

If you’re using a plastic pitcher and it’s meeting your needs, there’s no rush to replace it. But if you’re considering an upgrade, the steel options genuinely offer a better long-term experience. They minimize odors, resist scratching, and eliminate concerns about plastic degradation.

The cyberattack news adds important context. While hackers targeting water treatment facilities doesn’t mean your tap water is suddenly unsafe, it highlights vulnerabilities in water infrastructure. A well-maintained home filter adds extra protection against contamination, whether it’s from hackers, aging pipes, or seasonal runoff.

Remember, though, that “properly maintained” is the key phrase here. If a filter has an expired cartridge, it can actually concentrate contaminants instead of filtering them out. So, whatever system you choose, sticking to the replacement schedule is crucial, regardless of the brand name.

What People Are Saying

“I switched from a Brita to a stainless pitcher two years ago, and I’ll never go back. The plastic ones start smelling weird after a few months, no matter how often you clean them.”

“The Culligan certification stuff matters a lot to me. I want to see NSF stamps, not just marketing claims about what it removes.”

What To Keep an Eye On

• The FBI investigation into cyberattacks on water facilities in seven states is ongoing. Any findings could impact regulatory pressure on municipal water systems, affecting consumer demand for home filtration.
• Filter cartridge pricing is a long-term cost that many buyers overlook at purchase. Watch for subscription pricing models from all three brands—Boroux and Rorra are likely to promote auto-ship programs as they grow.
• NSF International, which certifies water filter performance claims, periodically updates its standards. Buyers should verify certification status when making a purchase, not just at launch.
