When to Replace your HEPA Filter?

When to Replace your HEPA Filter?

Its very hard to give a definite time for when to replace an old HEPA filter as there are many elements involved, for instance, humidity, filter location, usage time, the quality of air entering the HEPA and the quality of air filtration required.

In general terms, the HEPA filter should be changed every 3 to 6 months, which is a relatively broad average. When a filter's capacity to capture a large number of particles is reduced, it should be replaced. Let’s say, if you keep using a filter that is only 50% effective, that means it would take about double amount of time to clean the air in the same room compared to a normal HEPA filter. This is something that should be remembered when your HEPA starts to age.
