AllerAir - AirMedic Pro 6 Ultra Air Purifier

Thank you for this. I have been very impressed with allerair as well. They took my spec sheet from my recent window installs and figured out what we were dealing with. Super impressed. Will likely go this route. Thanks for sharing!!

So if memory serves correctly that specific model does not have HEPA filtration due to the large amount of carbon. If you go one model down that has \~20 something lbs of activated carbon that one will have the HEPA filter. Although you don't necessarily need HEPA to filter out PM2.5 so I think the AirMedic should still work just fine for that as even Corsi-Rosenthol boxes will do a great job of filtering out PM2.5 pollution from the air with wildfire smoke. The AirMedic filters should last longer between having to change them but they will be costly. Although IQAir filter replacements ain't cheap either. I'd personally go with whatever one you can get the fastest, you can't go wrong with either one.

I just ordered the AllerAir Smoke Eater which has over 30lbs+ of carbon (Los Angeles)

Sorry, “Smoke Eater”: [AirMedic Pro 6 Ultra S - Smoke Eater Air Purifier](https://allerair.com/products/airmedic-pro-6-ultra-s)

The first recommendation for new builds is **exhaust ventilation**. This is way cheaper than multiple sorbent media purifiers. You can do this by opening windows, building DIY Energy Recovery Ventilators (ERVs), or installing ERVs or Heat Recovery Ventilators (HRVs) as part of your HVAC system. ERVs or HRVs trade indoor air for "fresh" (oxygenated) outdoor air. This can reduce VOC and CO₂ levels. But the *non-DIY* versions may not be enough to counteract high levels of VOCs. Another problem is the exact mix of VOCs. The issue is that plain/untreated sorbent media do *not* have high removal efficiencies for all gaseous "species". You would need to modify something like plain activated carbon increase removal of formaldehyde, acetaldehyde, acetylene, ethylene, for example. See [American Hakko Products, Inc.'s Activated Carbon Capacity Index](https://kb.hakkousa.com/Uploads/Attachments/584400cf-c9f4-4201-99bf-33c4.pdf). If you wanted a more exact answer, you could hire an environmental consulting group to do gas testing. A cheaper option is a home test kit you send away for gas chromatography–mass spectrometry (GC-MS) analysis. If you only use plain/untreated sorbent media in purifiers, you may still have high levels of other VOCs. There's also the issue of competitive adsorption as the sorbent media begins to saturate. Potassium permanganate (KMnO₄) is an impregnating compound for activated carbon and activated alumina. It's a strong oxidizer that breaks down gases and often used to increase formaldehyde removal. But in highly complex air chemistries, it can produce new compounds. And KMnO₄ itself can off gas as it saturates or becomes spent. As far as actual purifiers are concerned, I would tend to suggest **AllerAir** over Austin Air and the IQAir HealthPro Plus. **Airpura** is another worthy alternative, although their units tend to be more expensive. Austin Air has about 15 lbs. of sorbent media for several models, but also particulates filtration. The [HealthPro Plus](https://cdn.shopify.com/s/files/1/0065/4780/0182/files/Tech-Specs_HPP-NE_120V_120924.pdf) only uses 5 lbs. of activated carbon pellets and KMnO₄ impregnated activated alumina spheres. This could saturate very quickly in a high VOCs environment. Certain [IQAir GC](https://cms.iqair.com/sites/default/files/documents/Tech-Specs_GC-NE_120V_130723.pdf) or GCX models have more sorbent media (especially the [GCX series](https://cms.iqair.com/sites/default/files/documents/Tech-Specs_GCX-NE_120V_130723_0.pdf)). AllerAir does offer some lower weight models. The [AllerAir AirMedic Pro 5 Plus (VOCARB option for VOCs)](https://allerair.com/products/airmedic-pro-5-plus-exec?variant=42969221454) has about 18 lbs. of carbon for $637.98. The model with the most carbon is the [AllerAir AirMedic Pro 6 Ultra Air Purifier (VOCARB for VOCs)](https://allerair.com/products/airmedic-pro-6-ultra?variant=42969115470) with 32-34 lbs. carbon at $1,019.98. **Important:** Exec and VOCARB blends are *plain/untreated carbon*. AllerAir does offer over 40 blends of carbon. You must contact them first to do this. But obviously you'd need to know the VOCs in your airspace first.

Ah okay. In this case, you would want to maximize sorbent media weight. As someone else mentioned below and as I've told others, you can also build your own sorbent media purifier via AC Infinity. This can save you quite a bit of money. AC Infinity sells [refillable carbon canisters](https://acinfinity.com/refillable-carbon-filters/), [inline fans](https://acinfinity.com/inline-fan-systems/), and [air filter boxes](https://acinfinity.com/air-filter-boxes/). But please note that AC Infinity sells untreated activated carbon or "charcoal" only. Some gases are not well adsorbed by untreated activated carbon. Instead you can buy potassium permanganate (KMnO₄) impregnated alumina or carbon, which you can buy from the likes of [Industrial Odor Control](https://www.industrialodorcontrol.com/activated-carbon.html), [Hepner Air Filters](https://hepnerairfilter.com/activated-carbon-potassium-permanganate/), or possibly [Hydrosil International](https://hydrosilintl.com/air-filtration/). I would recommend removing some of the AC Infinity untreated activated "charcoal" out of the canister and adding the KMnO₄ impregnated alumina or carbon instead. I don't know what percentage (50%?) would be ideal. r/AskChemistry could be helpful. If you're still keen on buying a sorbent purifier, you could go with the [Airpura C700DLX](https://www.airpura.com/products/c700-dlx-chemicals-and-gas-abatement-plus-air-purifier) or the [AllerAir AirMedic Pro 6 Ultra S - Smoke Eater Air Purifier](https://allerair.com/products/airmedic-pro-6-ultra-s). This AllerAir model has a 32-34 lbs. carbon canister and it's cheaper at $934.98. However, I don't know the exact blend of carbon, impregnating compounds, etc. You may want to ask Allerair the exact type(s) of carbon inside.

I just bought two allerair airmedic pro 6 ultra for my medical office. I called the company told them about my situation and they immediately connected me to their chemist to match a filter to my needs. I was impressed to say the least. The filter has 30 some pounds of carbon, which is the largest of all consumer grade purifiers. While there is no app or screen and the design is about 13 years old, What I have learned after trying a number of other filters like the Dyson and air oasis pro is that for me what really matters is carbon. This filter has a 5 inch deep carbon filter. They said I will know when the filter is ready to be replaced when it has gained about six extra pounds from absorbing all of the particulates. This brand does have a commercial branch for more specific needs.

I use AirMedic Pro 5 Air Purifier. 14LBS of carbon. Commercial grade fan that should last forever. Made of metal. Anything with a thin carbon sheet isn’t doing crap. Pro 14LBS Pro plus 18lbs Pro hd 23lbs Pro ultra 28lbs

I know! I feel like Allerair's marketing dept is really asleep at the wheel. They're included in almost no third party reviews but they seem to be very good. I actually got one of these really cheaply today on eBay. I bid ages ago and didn't expect to win. Do you have an Allerair?

I’m in Canada and unfortunately, wildfires have become part of life every summer. Last year was especially bad — the sky was orange for days, and even staying indoors didn’t help much. The smoke and smell would still find a way in, especially through my swamp cooler. I started waking up with headaches, a sore throat, and just feeling gross all the time. I tried a couple of those cheaper air purifiers from Amazon — the ones that say “HEPA” and “carbon filter” — but they honestly didn’t make a difference. The rooms still smelled like smoke, and I could still see dust floating around in the sunlight. Eventually, I bit the bullet and bought an AllerAir. It wasn’t cheap, but I was desperate. What really convinced me was how thick the carbon filter is... it’s like a solid chunk, not just a thin sheet. I didn't realize how important that was until I actually used it. Within a day or two of running it nonstop, the air in my room felt totally different. No more smoke smell, my throat felt better, and I wasn’t waking up with that weird heaviness in my chest. Now it’s basically my go-to as soon as wildfire season starts creeping in. It’s bulky and kind of industrial-looking compared to the sleek little ones online, but it actually works — which I guess is the point. I just wish I had bought it sooner instead of wasting money on cheaper units that couldn’t handle real smoke. Atmos C is also a decent brand, I have one of their units as well and it has been serving quite nicely over the last few years. Never had an issue with it! I hope this helps!

Allerair air purifiers are fantastic. Would strongly recommend. And they are local, so no tariffs!
