For IQAir HyperHEPAH Replacement Filter Compatible With IQAir Filter Replacement HeathPro Series Stage 3 F1 H13 True HEPA

Fit like the original.

Ordered this item several times. A decent price and reliability.

I'm a big fan of IQ Air Purifiers and have 4 of them. The filters are pricey, so I tried this off-brand to see if I could tell a difference. So far, it seems to work just as well.

I like the price I paid for this filter. It's comparable to the iqair brand replacements

Great filter fit perfectly

First, it was damaged. The size of the filter is slightly smaller, so there is a small gap where air can pass through without getting filtered. The styrofoam used is much softer than the hard and dense foam of the original IQAir PreMax.Update: Seller has informed me that they will send a replacement, but did not. Has not responded to me. Unreliable seller.

Needed to replace our IQAir PreMax Pre-filter and this came available on Amazon. First of all, this is just fraction of the cost compared to OEM model. Installation is a bit tedious but easy if you own a IQAir, need take out two top filters as they are nested on top of each other to replace the bottom Pre-filter. So far, it works fine, no issues. We will see how long it lasts compared the OEM model.FYI, we have our IQAir on 24/7 at level 1, and typically need to replace filters every 2 years.

Dimensions are perfect but there are noticeably fewer folds in the filter than other brands. I don't recommend this item for saving $10 over other 3rd party brands of the same filter.
