IQAir Replacement Pre-filter Element for HealthPro Line (F1 Filter)

The shipping from Amazon.com (product purchased from Witbecks and fulfilled by Amazon.com) was fast, the filters were packed well and factory sealed by IQAir.
I feel that the IQAir HEPA filters saved my life. Had chronic bronchitis in 2008 that would not go away. The doctor that released me from the hospital suggested that I get a HEPA filter (said that a Sharper Image type air filter would make me worse due to the ozone it creates). Searched on line and found the IQAir and all of the great reviews, bought two (1 for each level of our townhouse) and love them. I can tell as soon as I walk into the house the difference that they make. This is the second set of pre-filters I've replaced, the HEPA filters are still going strong. If you have asthma (which is what i have) or bad allergies, I would highly recommend an IQAir HEPA filter and you can't go wrong with Amazon.com and their great service!

This is the best air filter I have ever owned. IQAir really works well to clean the air in my bedroom. The first filter lasted 6 months with the device running 24 hours a day.
