How Often Should I Change My Lelit Coffee Machine Filter?

Water filtration is one of the most overlooked yet critical aspects of maintaining an espresso machine. If you own a Lelit machine, using and replacing the water filter properly can mean the difference between consistently excellent espresso and costly repairs down the line. But how often should you really change it? Let’s break it down.

Why Your Lelit Water Filter Matters

A high-quality water filter does more than just improve taste—it protects your machine from the damaging effects of mineral buildup. Here’s why it’s essential:

1. Prevents Limescale Build up – Hard water contains calcium and magnesium, which accumulate inside boilers, pipes, and valves, reducing efficiency and potentially causing permanent damage.

2. Preserves Coffee Flavour – Chlorine, sulfur, and other impurities in tap water can negatively affect extraction, leading to bitter or flat-tasting espresso.

3. Extends Machine Lifespan – Regular filtration reduces wear and tear, helping your Lelit machine perform at its best for years.

How Often to Replace Your Lelit Water Filter

The general rule is to replace your Lelit water filter every 1 to 2 months, but several factors influence this timeline:

1. Water Hardness Level

• Soft Water (0-3 gpg): Replace every 8 weeks approximately.

• Moderately Hard (3-6 gpg): Replace every 4-6 weeks approximately.

• Hard/Very Hard (7+ gpg): Replace every 3-4 weeks approximately.

You can test your water hardness with inexpensive strips or check your local water quality report.

2. Frequency of Use

• Daily Use (Multiple Shots/Day): Replace closer to 4 weeks approximately.

• Occasional Use (Few Times a Week): Can stretch to 6-8 weeks approximately.

3. Filter Type

• Standard Sediment Filters: Need more frequent changes.

• Ion Exchange Filters (Like Lelit’s): Last longer but still require regular replacement.

Signs Your Filter Needs Changing

Don’t just rely on the calendar—watch for these warning signs:

• Slower Water Flow – A clogged filter restricts water, affecting shot quality.

• Unusual Tastes or Odours – Metallic, bitter, or off-flavours suggest the filter is exhausted.

• Visible Scale in the Machine – White deposits mean minerals are slipping past the filter.

• Increased Machine Noise – Gurgling or struggling pumps can indicate flow issues.

Proper Filter Maintenance Tips

To get the most out of your Lelit filter:

• Soak Before First Use – If it’s a new filter, soak it in water for 5-10 minutes to activate it.

• Rinse Thoroughly – Flush the filter with fresh water before installation to remove carbon dust.

• Store Correctly – Keep unused filters sealed in a cool, dry place to prevent drying out.
