What Does a Brita Filter Take Out of Water? A Comparison with Advanced RO Systems

Brita filters are popular household water filtration devices designed to improve the taste, odor, and safety of tap water. But what exactly do they remove—and how do they compare to industrial-grade systems like the Walchin Ultra-Low Pressure RO Membrane?

✅ What Does a Brita Filter Remove?

Brita filters use activated carbon and ion-exchange resin to target a limited range of contaminants. They typically reduce or remove:

  • Chlorine (taste and odor)

  • Zinc

  • Copper

  • Cadmium

  • Mercury

  • Some particulates (like sediment)

Some upgraded Brita filters (e.g., Brita Elite) may also reduce lead and select pharmaceuticals. However, Brita filters do not remove dissolved salts, heavy metals at industrial levels, bacteria, viruses, or total dissolved solids (TDS).

⚠️ What Brita Filters Don’t Remove

  • Dissolved salts and minerals

  • PFAS (in most models)

  • Nitrates/Nitrites

  • Microorganisms (bacteria, viruses)

  • Fluoride

  • Hardness-causing minerals (calcium/magnesium)

For households or industries requiring deeper purification—especially for tap water, brackish water, or groundwater with high TDS—a reverse osmosis (RO) system is essential.


💧 Walchin RO Membranes: A Superior Solution

Unlike basic carbon filters, reverse osmosis membranes like the Walchin TW-8040-HF Ultra-Low Pressure RO Membrane go far beyond surface-level filtration.

They efficiently remove:

  • Dissolved salts (desalination)

  • Heavy metals

  • Microbial contaminants

  • Organic compounds

  • Chemical pollutants

With an advanced design for anti-pollution performance and high recovery at low pressure, Walchin membranes are ideal for groundwater and tap water treatment in industrial and commercial environments.

🧠 Final Takeaway

While Brita filters are a decent choice for basic taste and odor improvement, they don’t come close to the performance of professional-grade RO membranes. If you're dealing with polluted sources, TDS, or water safety concerns, trust in Walchin’s RO solutions to deliver reliable, high-purity water.
