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

Excellent, so happy to have a less expensive option & feel it seems comprable to the oem one! Fit is perfect.

I believe it works as well as the factory replacement.

They fit right into our Qair machine, and are much cheaper 👍

We love our whole house, air purifier, but the cost of replacing filters gets pretty expensive. What's happen to find these lower cost replacement filters which we cannot tell the difference in performance. Now we can feel better about replacing the filters, more often without breaking the bank. Exact size fit compared to original and cannot notice any difference in air quality great value

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.

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.

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

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.

Very good
