How do I fit the GQ-FILTER in a Winix GQ-FILTER?

No tools, a few minutes: 4 steps, listed on this page with the replacement video where the maker has one.

How long it lasts

Usually every 12 months. The filter light is a reminder, not a water-quality sensor.

After replacing: After fitting, hold the filter reset button until the filter light goes out.

Flow slows and taste drops off as the filter fills up. Changing on time is the whole point.
