A Guide for Hawkes Bay Homes
Clean, great-tasting water relies on one simple thing – a properly maintained filter. At Think Water Hawkes Bay, one of the most common questions we hear is, “How often should I change my water filter?”
For most Hawkes Bay households, the answer is every 6 to 12 months, depending on water quality, usage, and the type of system installed.
Why Filter Changes Are So Important
Your filter captures sediment, chlorine, rust, and other contaminants from your water supply. Over time, these particles build up and restrict flow. When a filter becomes blocked, it no longer works effectively and can start causing problems throughout your home.
Health Risks of Using an Old Filter
A clogged filter can become a breeding ground for bacteria. Instead of protecting your household, it may actually allow contaminants to pass through. This can result in unpleasant tastes and odours, and increased exposure to chlorine and other chemicals.
How a Blocked Filter Affects Your System
When water struggles to pass through a dirty filter, pressure builds up inside your system. This can lead to leaks, cracked housings, and unnecessary wear on pumps and fittings. What starts as a simple cartridge replacement can quickly turn into a costly repair if left too long.
Impact on Appliances
Poor filtration doesn’t just affect drinking water. Coffee machines, kettles, dishwashers, and hot water systems can all suffer from scale and sediment build-up. Regular filter changes help protect these appliances and keep them running efficiently for longer.

How Often Should You Change Your Filter?
As a general rule, most household filters should be replaced every 6 to 12 months. Sediment filters may need changing more frequently, especially in high-usage homes or areas with higher levels of particles in the water. If you’re unsure, the team at Think Water Hawkes Bay can assess your system and water quality.
