PureIllusion Scientifically Tested Gas & Odor Filter for IQAir HealthPro Series Air Purifier - Ultra Premium Filter fits V5 Cell Module - Genuine Crystalline

It's an excellent filter and the alternative to the original IQ VOC filter! It's a game changer for those allergic to the original IQ VOC filters. I’m so glad I gave this off-brand filter a try! The original IQ VOC filter gave me an allergic reaction affecting my sinuses and throat.I had to remove the original VOC filter from my IQ Air after giving it a chance several times and performing several isolation tests. It sadly left me only with the particle filtration. Fortunately, this off-brand VOC filter was the solution to the problem! I have been running the off-brand filter for over a week, and it performs very well and also does not give me any allergic reactions. I will be buying it again when the time comes!

I am a consulting scientist working on air filtration in adjacent areas of public health. I have no affiliation with this company (or with any other company that makes products for consumer air purifiers).I've been unimpressed with the design, quality, and/or safety of similar aftermarket carbon V-banks. This PureIllusion product is head and shoulders over the others I've examined. Most importantly, compared to IQAir's own offering, this aftermarket company leaves out the potassium permanganate, which is toxic and allergenic. You don't want to be exposed to potassium permanganate dust, which can cause severe eye damage, skin damage and more. Leakage from IQAir's V5 filter into the cabinet or onto hands while installing or disposing of the V5 would be of concern.Second, the third-party testing for toxic contaminants (I found the PDF available here on this page) was done by SGS, a leading Swiss-owned testing lab. Very impressive results!I’d ask PureIllusion repeat the SGS tests yearly, and also to provide a signed affidavit describing how the samples were selected (randomly by a neutral third party is ideal), rather than a single report on a batch of filters tested in 2023. That’s useful because contaminants can arise at any time. If in-house testing is done regularly, as it absolutely should be, those reports should also be made available.Although the possibility exists for deviations from the impressive report on the 2023 samples, nonetheless, this appears to be a more conscientious and thoughtful company than competitors.The density of the pellet packing and the adequacy of the seal of the PureIllusion V-bank filter also seems superior to some similar models on the market.Now, this is not a very sturdy filter design (glued cardboard chassis, fabric screening, etc), but this is the best of this type that I think I've seen.Finally, the pricing is quite fair for approximately 8 lbs of nicely distributed, non-contaminated AC in a well-designed chassis.UPDATE: Let me add an explanation for the reviewer who experienced a 'sickly sweet odor' with this filter but did not experience that with the OEM filter: That sweet odor is a sign that an AC carbon has reached its limit for adsorption; it's at the end of its useful life. It is unable to adsorb any more VOCs ('volatile organic compounds'; a range of airborne chemicals you are inhaling). So, that means it's time to replace it.The AC carbon functions by *trapping* the VOCs, but the permaganate in the OEM filter functions differently, by *oxidizing* a range of VOCs (breaking them down into other chemicals, and releasing many of those chemicals back into the air. Some of these oxidation products are not necessarily safer than the original compounds, and some could be more irritating or have different health effects; they might not be odorous, but that doesn't mean they're safer to inhale). Oxidizing is also how bleach, ozone, and hydrogen peroxide all break down odorous chemicals. The permanganate is probably continuing to oxidize in the OEM filter even after the carbon has reached its carrying capacity. This is arguably advantageous in terms of clearing the air, with the caveats stated above. But it's more dangerous in *other* ways, because the permanganate is a very potent irritant to lungs, skin, and eyes. People commonly report a lot of purple dust when they handle filters with permaganate in the matrix, and that is a visible sign that they are being exposed to permaganate. Not all exposure will be visible to the naked eye, however. The end user has to decide which concerns them more. In any case, when an AC carbon filter begins to emit that sweet odor, it is time to replace it.I received no kind of compensation for this review, and my review was not solicited.

Working wonderfully on my Iqair purifyer. I was apprehensive at first... but this will be the way to go for future replacements.

We have had an iQair air purifier for many years. The filters last for years, but they are expensive when replacing them. The Pureillusion versions of the replacements fit perfectly and are such a good replacement. I am very happy with the quality of these filters.

This replacement filter does the job and fits perfectly. There were a couple of things that we noticed right away and swapped the old IQair filter back and forth to make sure. This filter is heavier, which is a potential bonus if there is more filter media or it could mean it is less porous and won’t be as efficient as the OEM. The other noticeable trait of this filter is that it must not flow as easily as the OEM because it makes the filter noisier at all settings. Ours is in the bedroom so we have to run the filter at a lower setting to sleep. If you have your filter somewhere else in your house then that’s probably not an issue. We applaud the fact there is a replacement out there but there are some trade-offs to be aware of. Not sure if we will buy another one when this one needs replacing but it certainly works.

Thank you for saving me those big bucks, Purellusion! I purchased the carbon odor filter to add as a third filter to my IQAir system, and it's been fantastic. It's as simple as drop and go. Instructions are clear and the price was fair. Will repurchase when the time comes. Love this!

This carbon filter makes a very noticeable improvement in filtering out my neighbor's smokes, including not only traditional types of tobacco, but also various kinds of E-cigarettes chemicals. The original V5-Cell from IQ Air, sadly, is unable to produce any noticeable improvement. I think it could be due to the fact that the IQ Air V5-Cell contains only 6 pounds of activated carbon, whereas this one contains 7.5 pounds. That extra one and a half pounds of carbon maybe is the determining factor of its effectiveness.The only thing this Pure Illusion carbon filter still needs to improve is the carton housing--it is not as solidly built as that of the original IQ Air. As a result, my first one had a problem of those carbon granules falling out because the five-stripe housing that contain the carbon granules were not securely glued to the carton frame. I had to spend quite a bit of time repair it to stop the leak.Update of my review (6/4/2022). I am adding one more star to my previous review, because I am quite blown away by the customer service of this company. Not only are their products as good as, or better (in the case of the stage 2 filter) than the IQ Air filter, their customer service is absolutely fantastic too. After learning from my review that my first filter was damaged during the shipping, they went through the trouble of redesign their packaging material, then sent me a new one free of charge. In addition, they are also in the process of improving the design of their carton housing after I made the suggestion of strengthen the attachment of the strips to the frame by adding staples, instead of using only glue. Highly recommend this company's products. Two thumbs up!
