New Filter Taste or Smell

It’s common to notice a temporary taste or smell after installing a new water filter. In most cases, this is a normal part of the break-in process and does not indicate a problem with the filter or water quality.

These sensations typically resolve after the filter has been flushed and used for a short period.

Common Reasons for Taste or Smell With a New Filter

1. New Filter Break-In

New filtration media, especially activated carbon, may initially release:

• A mild carbon or “new” smell

• A neutral, earthy, or slightly unusual taste

This is normal, temporary, and is not harmful.

2. Incomplete Flushing

If a new filter has not been fully flushed or primed:

• Residual air or harmless media fines may remain

• Taste or odor may persist longer than expected

Following the recommended flushing/priming instructions can help remove these residuals quickly.

3. Removal of Familiar Water Compounds

When chlorine or chloramine is removed:

• Water may smell or taste different than you’re used to

• The absence of these compounds can be unusual at first

Many users adjust and prefer the new taste within a few days.

4. Reverse Osmosis and High-Purity Systems

Highly purified water can smell or taste different due to:

• Very low dissolved solids

• Reduced mineral content

This is expected and not a sign of malfunction.

What You Should Do

• Prime/flush the system according to the product instructions

• Run water through the filter for the recommended time or volume

• Use the system normally for several days

• Avoid judging taste immediately after installation

Most taste or smell concerns resolve on their own.
