Air Cleaners Filter Life Q & A – Why Does the Life of Filters Vary?

Air filter life expectancy depends on three factors

Added by: David Barnaby

Editorial Notes: The life of air purifier filters depends on a number of factors which is explained by David Barnaby below. In my home with constant use my pre-filters lasted 8-10 months. In the office (highly polluted by a busy road) they lasted 4 months.

Air Cleaners and Filter Life

Dear Renee,
The life expectancy of the filters we list on our website for the IQAir Healthpro air purifiers are dependent on 3 factors.

1. How many hours a day you run the air cleaner?
2. On what speed do you run the machine?
3. On what pollution setting do you run the filter? This is an index from 1 to 9 with 1 being for the cleanest environment and 9 being for the dirtiest conditions?

If you go to Chapter 3, page 16 in your IQAir Air Purifier owner’s manual there is a chart for each of the three filters depicting how many hours the filter will last based on the fan speed and the dust index. As you can see you will get variations from 2 to 18 months depending on the speed you run it on. As far as the dust index goes, the filters come from the factory set at 4 and it is recommended you leave them at 4 unless you are aware of extremes of clean or dirty air. So assuming the dust index of 4, the pre-filter will last between 2.5 and 18.25 months.

I apologize for any confusion we may have caused and I hope my explanation clears up any questions you may have. If you have any questions concerning any of this please feel free to contact us.

Thank you,
Dave Barnaby
