IQAir Replacement HEPA Filter for HealthPro Line

I have used the IQ Air brand filters in my Health Pro Plus for years now, but with all the recent issues with the bad smell and out gassing coming from some of the IQ Air HEPA filter I am giving this product only 3 stars. Being unsatisfied with the product, I started looking for an alternative filter manufacturer.
I found a filter manufacturer in New York (USA) that builds filters for the aerospace and medical industry. They now carry a full line of replacement filters for Health Pro and Health Pro Plus. The filters are housed in an aluminum housing (not Styrofoam like the IQ Air ones), they are exceedingly well built and meet the same HEPA specifications as the IQ Air brand filters. The added bonus is that since they are built here in the USA they cost less. I highly recommend "HEPA Air Direct" filters as a high quality and cost effective alternative to the IQ Air filters.

I have had an older HealthPro Plus and just changed the HEPA filter. It smells bad. The same holds true on a new unit that I just put into service. I have read comments from others and understand that it is the newer HEPA filter that is causing the problem. I would not recommend any of the HealthPro models for purchase at this time, unless the issue of the smell has been taken care of by IQAir. Up until now, my older unit worked great, my wife was quite happy with it. Now, she hates it. I now have over $2,000 worth of air cleaners and spare filters, that I must consider replacing with something else from a different manufacturer.

As with the other reviews I am sad to say the chemical smell issue is still happening with IQ Air HEPA filters. I am trying to work with IQ Air support but the fact they have not addressed this by now is an insult.

Update: IQAir quickly replaced the defective filter. Smell is close to original filter and much better than the defective. Not sure how so many defective filters got passed quality control...
