Excellent
This is a great alternative for the overpriced filter from the manufacturer. Since the prefilter needs to be replaced more often than the other filters, using this alternative can save you a lot of money in the long run.
-
Fits like OEM
Great value for the money.

Product fits IQAir, but there is no evaluation of performance
I was a bit disappointed with this product. It appears to be a typical knock-off with no instructions included and no indication of which side is up on the filter. The upper and lower surfaces appear to be the same, unlike the OEM product. There is no performance data provided, so there is no way to know how well it performs or how long it will actually hold up.

good value product
easy to assemble, seemed well constructed.

Good value for the money
I use this as a replacement for the original Oem Hepa filter. A lot cheaper and does the job.
-
Fits perfectly. Quality product.
Packaging is a little extreme for something that isn't breakable - but product is great at an excellent price.

Works great
A little expensive for us but since we live in a high fire area we have a lot of smoke from the fires and it really keeps the house clear. It’s a life saver with all my allergies. Just wish set something we need for our health didn’t cost quite this much.

great quality air
air feels exactly the same as with original filters, great alternative. No allergies.

A nice replacement filter
This replacement filter came in a quality box, and had nice instructions inside. The included instructions on how to reset the filter life was a very nice touch. Faster than trying to figure it out from the manual. The filter fit perfectly. This item is noticeably lighter than the OEM filter. I believe that it is because it uses standard density polystyrene foam, while the OEM filter uses high density. The other difference I found is that the OEM filter has spacers to keep the pleats in the filter very even. This replacement filter does not, but I doubt that it has significant impact, especially considering the savings over the OEM filter.

Perfict fit in IQAir filter.
Prompt shipment.

Great filter, even better price
Anyone who owns an iQair filtration unit knows that they are some of the best devices on the market. What's not so good is the extremely high cost of the replacement parts which can run close to about $1000 a yr. These non OEM replacements are very well made and fit perfectly and are significantly lower cost.

Perfect replacement for OEM filter
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.
