GC MultiGas NE

To get rid of VOCs you need a lot of absorbent substrate, 10 pounds or more. IQAir GC multigas works, other vendors include airpura, allerair, austin.

For VOC removal the generally recommended manufacturers are Airpura, Allerair, Austin, IQAir all of which have filters with 10 or more pounds of carbon. The AirDoctor 1000 has a relatively small Carbon filter which would have to be replaced more frequently than the others. This is reflected in the cost of the replacement filters which run \~$72 where replacements for the others run in the 100's. Doubt that it is as effective due to its small size. I use Austin and IQAir GC Multigas units. Just replaced the Austin filters with Immunity machine filters and saw significant improvement, but at the cost of \~$700 per filter. They are supposed to last 5 years. If you have to replace before that they reduce the cost. Consumer Reports (subscription required) has extensive discussions about air filters and reviews for filters without Carbon.

I use Austin Immunity Machines and IQAIR GC Multigas.

Manufacturers often mentioned are Airpura, Allerair, Austin, IQAir. Try to get one with a return policy, such as the 30 days offered by IQAir. There can be some interactions with the carbon which might produce some odd smells. If you are particularly sensitive it is also possible it might not work for you, particularly if you are outside the bubble of clean air around the machine. I own several GC MultiGas units. It was the only VOC model available when I bought it almost 20 years ago. Looking at the IQAir website I see there are quite a few of them now. I would contact them to find out which model would best meet your needs. Let us know how it goes!

1. Whirlpool AP450, Honeywell HA300BHD, IQAir GC Multigas, Austin Healthmate and Immunity machines. Have had some of these running without problems for 10-20 years so models have likely changed. Range in price from \~$224 to \~$!400. 2. Generic filters - in general not a great idea. Filters are sized to fit the casing and the fan is matched to the filter. Might be done but a bit risky. 3. Although I haven't needed to purchase machines recently my suspicion is that the "smarter" and more automated the machine is (auto speed, remote, etc.) the less likely they will be controllable by a smart power switch. 4. For printer and VOC removal the best machines run $1K or more. Filters can run as much as $700 (Austin Immunity Machine), but can last for 5 years.

1. Yes, I have them all on Satechi Smart Plugs. 2. I did check Amazon for 3rd party HA300BHD filters and they do exist. 3rd party Filters will more likely be available for models that have been out there a long time as there will be more units sold making it profitable for 3rd parties. This one, or similar ones from them, has been out for > 10 years. No way to tell about their quality or effectiveness. Since I am extremely sensitive I personally don't want to take the risk. Given their specialized nature don't see any for Austin or IQAir. 3. You need to choose a company that has been doing this for a long time and is successful.

For best VOC removal, such as mycotoxins, you need a lot of absorbent media. Checkout Airpura, Allerair, Austin, IQAir. All are in the $1k range. I'm unsure whether any filter will eliminate mold sensitivities. Did see an improvement when upgraded my Austins with Immunity Machine filters but molds still aren't totally controlled. There are clinics which can treat mycotoxin sensitivities. Can be quite expensive.

Running both IQAir and Austin Immunity Machines in my major rooms particulates run from 0 to under 10.

I have had my Austin, IQAir, Honeywell and Whirlpool machines for as much as \~20 years and have had no problems with filter replacements.

The 4 vendors with the best VOC filters are Airpura, Allerair, Austin, IQAir. Absorbent media composition and weight vary by manufacturer. IQAir has models that go up to 32 pounds of media, at least according to google search. Note that no VOC filter will remove all VOCs. They do well with some chemicals, partially control some, and totally ignore others. I use IQAirs and Austin Immunity Machines, multiple units per room unless you want to put up with the noise running the fans on high speed. Had a room repainted and requested a low VOC paint. Was pleasantly surprised that I had no problems with the paint even though I am extremely chemically sensitive. It is possible that the renovations don't cause a VOC problem at all, or maybe just for a few days.

My Austin, IQAir, Honeywell and Whirlpool filters all work with smart plugs. When you purchase make sure you can return if it doesn't work as features change over time.

Those units have very small carbon filters. They either will be ineffective or won't last that long. A good VOC filter has 10 or more pounds of absorbent media and run in the $1K range. Checkout Airpura, Allerair, Austin, IQAir. Just be aware that the VOCs will only be reduced in the bubble of clear air around the filter. If you have a very large room multiple filters may be required.

Austins are in the same price range as all of the good VOC filters with 10 or more pounds of activated absorbent media. All are in the $1K range. Filters with less media, such as a Winix, will either be less effective or require more frequent filter changes. Being chemically sensitive I use multiple Austin and IQAir units.

As an air quality professional I have tried and tested numerous units. The IQAir Multigas GC is by far the most effective unit and is the preferred one for people with chemical sensitivities. Unfortunately the company has dismal customer service, follows deceptive practices and denies problems when they arise. If I can ever find an air purifier as effective as this one I will definitely guide my clients towards that brand and model. Unfortunately I have sold hundreds of Multigas GC units because they work so well. I don't feel that Airpura, Allerair, Austin Air etc are in the same league from the standpoint of results but Austin Air machines are very good and that company is a US company, the machines are made in the US and it has excellent customer service so I recommend that brand a lot for general air quality.

IQ Air, though they are expensive. we have 3 of GC multigas. gold standard.

IQAir Health Pro Plus or MultiGas units are the best you can buy for apartments. The IQAir Perfect 16 (may have newer models now for all these) is the way to go for whole house. They are the defacto best of the best. They are on Airforce 1 for the last 2 decades. In hospitals, clean rooms. They are the best.

that's because you are using a 'feeling', I am using a $5,000 laser particle scanner and have used and tested literally hundreds of them because until I got iqair I was getting pneumonia 3-4 times a year because that's how bad my allergies are. I haven't had pneumonia in almost 10 years now and I continue to test other air purifiers yearly. When I tell you the brand is the best it's because I'm absolutely certain and I have an financial freedom to pursue it in a way a lot of people cannot. Trust me. I'm doing you a huge favor. I can test up to .002 micron size particulates per cubic foot, and I can tell you that IQAir is the only unit that after several years with no filter change achieves 90% efficacy while the 2nd runner up is at 3% after 9 months. What I am not doing is making these statements out of brand loyalty.

yes there is a lot of hyperbole around them, good marketing, less on air filtration. 1) The UV works to disrupt the dna, but it's not really relevant. The hepa is trapping the spores that are floating around your environment, the UV doesn't need to disrupt them as they haven't colonized yet... and you are replacing your filters regularly if you are half bright because it's mold and you don't want allow them to do so). So the UV does nothing to the air ducts and other places where the mold is actually colonizing... which puts it back to the main issue which is air flow. The unit can only ever filter as much air as it touches, and how fast the filter gets saturated with mold in your environment. It is highly dependent on your place. That said, if I recall the company said the filters last up 2 years and I found that they were fairly useless after 3 months with a 40% efficacy after that time (running on high 24/7). If I were you I'd go with the GC units (they are more expensive IQAIR) but you are already compromised and you don't need the VOC exposure, RADON, etc... and they will mitigate RADON believe it or not I have an Air things unit that tells me my RADON exposure and I see a stark difference with the GC unit. The new ones (and I need to think about upgrading mine) have some pretty good API options too, their software puts together a good summary page and shows you what you are filtering from what I understand.

Iqair bar none. Simply the best money can buy. Anything less is honestly wasting your money because your filter will be clogged up in a few weeks and you will have nothing being purified. Seriously, I've tested these things extensively with a laser particle scanner. The cost in filter replacements (contrary to mfg saying replace every xx) drives your total cost of ownership through the roof. The mfg suggest on every major brand allows for a 85% reduction on average in performance because it is still "making a difference". I've tested my iqair machines and after 5 years with no replacements (just cleaning out the pre-filter with my air compressor every few years) is still operating at over 90%. They under promise and over deliver. /end my rant I live with severe allergies that can cause pneumonia so it's a big deal for me. I haven't had it in 10 years because of IQAir. Prior to that it was 2-3 times a year.

IQAir is really the best air purifier, it's about the filter quality and how long the efficacy lasts. Most air filters on the market to very well for about 2 months and then drop to 3-15% efficacy (from 100%). The IQAir is the only one on the market that I've seen stay consistently over 90% for YEARS.

yeah crazy isn't it? Total cost of ownership is much lower. \*tested with laser particle scanner

IQ Air multi gas. My doctors offices, pulmonologist, cardiologist, etc . uses them. It really helps me breathe at home.
