 Money Saving Tip Below Jan 30, 2011
By Deep Thought
Save your money and dont buy this kit. Instead buy the 5 filter replacement package. I bought this kit, which comes with three filters, and found that the filters themselves fit snugly enough in the bottom of the IQAir that using the brackets is not really necessary. After you give it a try you will probably feel the same way. It is also a heck of a lot less trouble to replace them this way as well. If you decide that you want the brackets, you can always order the kit later after trying the filter on it's own. I wont be installing mine... anyone want it?
Update 12/24/11
I have now used all three of the filters that came with the kit and have ordered the 5-pack of filters only. I find these filters extremely effective at capturing coarse dust particles and prolonging the life of the prefilter. I replaced my prefilter after double it's normal life. I am still adamant that the kit is not at all necessary, and that the filters alone easily fit snugly in place right under the prefilter. In addition to fitting snugly in place, the suction of the air makes it effectivley clamped right on it. The IQ air itself is a wonderful machine.

 Wait till you see the gunk that accumulates on this coarse filter May 29, 2011
By V. Juvvigunta
Totally useful.
I live near a busy cross section and so far I have used up two of the coarse ones and just today installed the last coarse one and a new pre-filter. The coarse one that I removed was coated in fine sticky dust while the pre-filter was not too bad.
As far the life of the pre-filter goes, I simply force the unit into believing that I have a new pre-filter the first time the warning comes up. The second time it comes up, I change the pre-filter. My current frequency has been to change the coarse filter every 9-12 months (visual insepection) and the pre-filter at half the frequency.
While I am not sure the bracket is worth all that money, it does keep the filters in place and so far the results have been outstanding.
Also, note that it does say that the coarse filters can be washed multiple times before replacement is needed. Depends on what you find when you take the coarse filter out I guess. I have always discarded them so far as I did not think I could get the fine sticky dust off of them. I will try once at some point and see if I can be more green.

A Required Filter For All Compatible IQAir Units Jun 20, 2010
By Adam Lau
Though IQAir may tell you otherwise, the PF40 is a necessary component for maximum effectiveness and unit longevity. Despite the three star review, the PF40 is a highly recommended addition to compatible IQAir units. It is unfortunate that IQAir has not provided the PF40 as a standard option, thereby forcing customers to swap out the prefilter prematurely. Lose a half-point for an ungasketed seal which allows for bypass. Lose another half-point for not providing extended filter change reminders for units with the PF40 installed.
