Type of Filter

These air purifiers use activated carbon and alumina. This cartridge is used to remove chemicals and odors from the air.

It has a pre-filter to remove any larger particles from the air. There is also a post filter that will trap any remaining particles. This makes the IQAir Multigas great at particle filtration too.

Maintenance Cost

The pre-filter is about $70. It will last 6 - 18 months.

The post-filter is about $96. It will last 1 - 2 years.

The GC gas cartridge is about $295 and it will last 1 - 3 years.

It is hard to say exactly how long each filter will last. It depends on the environment. So your cost to maintain this air purifier will vary.

To find a ballpark figure, we assume a pre-filter will last 1 year, the post filter 2 years and the GC gas cartridge 2 years. This would give us an average cost of $265 each year.
