How Often Should You Change Your RO Filters? A Complete Guide

The Secret to Long-Lasting RO Purifiers

Many people think that once an RO is installed, it will work forever without maintenance. This is a dangerous myth! Over time, filters get clogged with dirt, sand, and chemicals. Here is the ultimate timeline for changing your RO filters:

Filter Replacement Schedule:

• Pre-Filter (Outside Spun Filter): Change every 3 to 4 months. This takes the maximum load of dirt and mud from the main supply.
• Carbon Filter: Change every 8 to 12 months. This filter absorbs chlorine and foul odors from the water.
• RO Membrane: Change every 1.5 to 2 years (depending on your raw water TDS). This is the heart of the system that removes dissolved salts.
• UV Lamp: Change every 12 months to ensure 100% protection against living bacteria.

Pro Tip: If your water flow has reduced drastically or tastes bitter, it's time for a filter change. Contact us for genuine spare parts!
