When should I replace my RO pre-filter and post-filter?

+ -

Sediment and carbon pre-filters are typically replaced every 6–12 months, while the polishing post-carbon filter should also be changed annually to maintain water taste and purity. Many Glacierfresh RO systems follow the same schedule for reverse osmosis replacement filters to ensure stable filtration performance.

ow do I know if my RO membrane needs replacement?

+ -

Use a TDS meter to measure filtration efficiency. If the rejection rate drops below about 90 percent, for example tap water at 200 ppm producing RO water above 20 ppm, the membrane may be worn out. Glacierfresh RO systems use similar monitoring methods to track membrane performance.

What happens if I don’t replace RO filters on time?

+ -

Exhausted carbon filters can allow chlorine to pass through, which may permanently damage the RO membrane. Clogged pre-filters also reduce pressure and strain the system pump. Following the replacement schedule recommended for Glacierfresh RO filtration systems helps prevent these issues.

Can old RO filters affect water taste?

+ -

Yes. When post-carbon filters become saturated, they can allow organic compounds and tank odors to affect the final taste of the water. Replacing Glacierfresh RO filters on time ensures clean, crisp-tasting drinking water.

How long does an RO membrane last?

+ -

Typically 2 to 3 years. Its lifespan depends heavily on pre-filtration quality and the hardness of the source water. Softened water can extend a high-quality membrane's life to up to 5 years.

Can clogged RO filters reduce water production?

+ -

Yes. Blocked sediment filters reduce pressure reaching the membrane. Since RO systems typically require 40–60 PSI to operate effectively, reduced pressure can significantly slow or stop water production.
