I have the Coway Airmega and an Austin bedroom machine, and they seem to be equally good. The Austin cost significantly more.
I have an Austin bedroom machine, a Coway airmega, and a gigantic Midea dehumidifier. Austin takes up a lot of space and I wouldn't say for sure that it works better than the Coway, which was less than a fifth of the price and has a small footprint. One issue with the Coway is that it has lights on top that can't be turned off, so it's unsuitable for a bedroom.
I recommend Austin Air Systems. They are excellent, although somewhat expensive. We bought one for my mother who had COPD, and it worked great. I recommend either the Healthmate Plus or the Bedroom Machine. They have a 5 year filter and there is also a pre-filter. This system was recommended by my mother’s pulmonologist. It has been in use for almost 5 years. These systems have been used in schools and hospitals in California when they had to purify the air because of the wildfires. Go to their website to learn more. Even though rather expensive, it is worth it to get a good system that actually works. There are different machines and levels of purification, depending on one’s needs.
I have a couple of models: Immunity Machine, Healthmate Plus, bedroom machine. There have been some reviews stating that Austins are slower at clearing a room of particulates. My main concern is VOCs and since I run 3-4 filters in each room that isn't a concern for me. Am now testing the immunity machine. Seems to do a much better job with VOCs, although final results will take a while. What is your concern with IQAair?
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.
Austin filters for the full sized machines are interchangeable. I had a couple of healthmate Plus and bedroom machines whose filters had reached the end of their lifetimes. Replaced the old filters with immunity filters.
I have had my Austin, IQAir, Honeywell and Whirlpool machines for as much as \~20 years and have had no problems with filter replacements.
I have an Austin and it’s awesome [https://theairpurifierstore.com/collections/all?sort\_by=price-descending&filter.p.vendor=Austin+Air&filter.v.price.gte=&filter.v.price.lte=&gad\_source=1&gad\_campaignid=22332875938&gbraid=0AAAAADflrdglTs6aJ66BNRtJ1N3phGbsn&gclid=Cj0KCQiA6NTJBhDEARIsAB7QHD3FgGm5GRcqfercD8uS5zVaLYjjROaYNjKwtRkobd2E9wQl8kwdHagaAnP2EALw\_wcB](https://theairpurifierstore.com/collections/all?sort_by=price-descending&filter.p.vendor=Austin+Air&filter.v.price.gte=&filter.v.price.lte=&gad_source=1&gad_campaignid=22332875938&gbraid=0AAAAADflrdglTs6aJ66BNRtJ1N3phGbsn&gclid=Cj0KCQiA6NTJBhDEARIsAB7QHD3FgGm5GRcqfercD8uS5zVaLYjjROaYNjKwtRkobd2E9wQl8kwdHagaAnP2EALw_wcB)
Hi, I have the Air Bedroom machine. The link I referenced has it for under $1000, I paid $1300 during Covid
1. We have a search engine. 2. You have reviewed zero buyer's guides which will aid you on the specifics and use cases of air purifiers. 3. This is not /r/good nor is this /r/reasonablypriced, you get recommended a BIFL unit and if you can't afford it, tough titties. 4. Austin Air Bedroom machine, if you can get it, is BIFL.
1. Step zero or purchasing this product is finding/posting the sq ft of the area served. You have not done so, so you are not ready to buy. 2. View 5 air purifier buyer's guides to gain knowledge. https://www.consumerreports.org/appliances/air-purifiers/buying-guide/ is one and google will find you others. 3. Your root cause is likely NOT dust as that is your assumption. You are best served by visiting a doctor and discussing allergies. 4. You do have a price range as a PM1 unit costs more than your car. 5. Silence is not a factor in any unit that conditions the air as you will either accept it or return it. You cannot ask about this metric online ever as that comes from dB and Hz. Makers may list dB using an unknown distance and unknown dB meter which means literally zero and they never list Hz which is a critical annoyance factor that varies to you...my unit may be whisper quiet to me as I was raised in a sawmill and when you buy it based on my recommendation it sounds like an annoying screech. 6. LEDs are not a metric as zero people know how many/what brightness will annoy you and they can all be solved with pieces of electrical tape. Austin Air is a BIFL brand when you factor in sizing, the 5 year warranty and 5 year filter replacement cycle. Which flavor of them is right for you....dunno as you didn't state the sq ft served.
Austin Air. I have two of the bedroom models and each of them have been running continuously for the past five years without a single problem.
Austin Air. Pricey but solid - made of metal in US. Filters last 5 years on normal conditions. Have had the same machine running 24/7 since 2013!
I can name two! The AustinAir HEPAs are basically a big metal box with a motor. The plastic in it is the squirrel cage fan itself and maybe the speed dial cover? Same for the SmarterHEPA (outside the US Smart Air) Blast and Blast Mini models. They again are a big metal box with close to zero plastic outside the fan itself. Of course even the motor will have plastic covering the wires or things like that. And the power cord has a plastic coating so nothing these days will be 100% plastic free but these two models are very close. Also both of them are really great HEPA filters! Basically no ‘features’ to either, just a big box with a fan and a speed dial. I had the AustinAir for like 30 years running 24/7.
