Scientifically Tested Filter for IQAir HealthPro Series Air Purifier - Ultra mium Filter fits Max Module - Genuine Crystalline Filter

Good fit

First time I’ve purchased a non IQ Air filter in 17 years or owning my IQAir Air Cleaner. What prompted me to try the PureIllusion filter was a price increase to an already expensive filter along with now having to pay shipping charges. The IQAir supplied filters have always been topnotch in performance, fit and on time shipping so the PureIllusion has big shoes to fill. Anyway, about the name, Pure Illusion! Who chose that name? From Miriam Webster, the definition of illusion is: Definition of illusion 1a(1) : a misleading image presented to the vision : OPTICAL ILLUSION (2) : something that deceives or misleads intellectually b(1) : perception of something objectively existing in such a way as to cause misinterpretation of its actual nature The product is a Pure Illusion? I certainly hope not. Perhaps a rebranding is in order. About the product, the PureIllusion HealthPro pre filter. It is sturdy in construction, feels about the same as the IQAir filter and as I had mentioned fits perfectly. After starting up my HealthPro there were no strange odors or signs of anything amiss. Since I just now installed the filter I will post and update later about its performance. Starting with a pre filter as my first non OEM experiment seemed pretty risk free. Next I’ll try the odor and VOC filter when the HealthPro signals a change is needed. Still debating about the HyperHepa replacement and that decision will be based upon the performance of the PureIllusion filters. UPDATE 8/22 The Pure Illusion IQAir pre filter is working great. My air monitor shows zero change from the time an OEM IQAir pre filter was in service. I detect the same airflow and noise from OEM filter. My air quality PM2.5 is exactly between 0.0 to 2 as it always has been. The higher value appears when my house is being cleaned or multiple people are around. For me this is now my go to pre filter for my IQAir Healthpro Plus. Definitely recommend!

EASY to replace in air cleaner lasts a long time

Fits snugly onto ridges in the machine. Great customer support when first package went missing.

Came with clear instructions and had a sticker indicating which side is "up". Fit perfectly and was considerably less expensive than the OEM filter. Will definitely order again when needed.
