When choosing a stainless steel water filter, the type of metal matters. The two most common grades—304 and 316 stainless steel—offer different benefits. So, which one is right for your needs? Let’s compare their key differences.
1. Corrosion Resistance
304 Stainless Steel: Offers good resistance to rust and corrosion, making it suitable for most tap water conditions. However, it may degrade in areas with high chlorine or salt content.
316 Stainless Steel: Contains molybdenum, enhancing its resistance to chlorides, saltwater, and harsh chemicals. Ideal for coastal regions or homes with heavily treated water.
2. Durability & Longevity
304: A cost-effective choice for standard water filtration, lasting years under normal conditions.
316: More durable in aggressive environments, ensuring longer lifespan in areas with poor water quality.
3. Price Difference
304 is more affordable, making it popular for budget-friendly filters.
316 is pricier but justified in high-corrosion scenarios where longevity is critical.
4. Best Use Cases
✔ Choose 304 If:
Your water source has low chloride/salt levels.
You want a cost-efficient yet reliable filter.
✔ Choose 316 If:
You live near the ocean or use well water with high mineral content.
You need maximum durability for industrial or commercial filtration.
Final Verdict
For most households, 304 stainless steel provides excellent performance at a lower cost. However, if you face highly corrosive water conditions, investing in 316 stainless steel ensures superior protection and longevity.
