Austin Air - Immunity Machine

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?

According to Consumer Reports (subscription required): Only 2 out of 7 Winix models rated good to fair, the rest poor Only 1 Coway model rated good. Rest poor to unacceptable. 1512 poor.

I use Austin Immunity machine and iQair GC Multigas units as VOCs are a major concern for me. Not rated.

Air filters do catch some dust but that is not their primary use. As particles are heavy most settle to the floor before hitting the filter. BlueAir filters have the highest overall ratings.

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 very best one is a PM1 unit. You will have to have a commercial contractor come out and give you a personalized quotation. And once you find out the price, you will likely back off your price doesn't matter bravado as the unit will cost as much as your car. You are not asking a BIFL question, so quit trying to shoehorn it as such. An air purifier is purchased based on sq ft of use and since we don't know if you want a room or whole house done, zero people here can give you advice worth a damn. Austin Air is the hive mind BIFL unit and is a PM 2.5 AKA HEPA unit. A HEPA unit is a HEPA unit, but Austin's killer warranty and filter period puts it in the top spot.

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.

I have 3 of these because I have Mast Cell Activation Syndrome & they have helped so much.

IQAir and Austin Air are the go-to “buy it for life” purifiers. They really have long-lasting filters and proven performance on my end

Austin Air is what I use in my home now. I own a. Filtration business, and I've tried about 9 different types in my own home over the past 3 years - this is far and away my favorite. The second best would be the BlueAir systems.

Austin Air, Air Oasis are some of the highest quality. I just bought an Air Oasis to sleep next to as I have CIRS

I have an Austin Air HEPA filter wired into a Homeseer Z-wave fan controller.  Their air purifiers are electrically just simple A/C fans, so the fan controller is able to regulate its speed (4 speeds), and HA is set up to adjust it based on an external air quality sensor.

Austin Air Cleaner. A little more than your budget. Phenomenal service. Check out the website. https://austinairsystems.com/?srsltid=AfmBOopJTNH0UqEz3X8EwSesYWb0Q1msSn9rd8Kh-CGMAW8MCK0ep27I

I just looked at Coway for a possible second unit but just decided to stock with the Austin. I recently started leaving it running 24/7 and the difference is remarkable. I got 4 years out of the first filter and 3 from the second because I made the mistake of using it during a house reno. They prorate replacements. I've cheaped out on too many things only to end up buying the better one eventually anyway.

IqAir, Austin, Levoit They are all running right now at home. Visitors often tell me the house smells very clean and pure. I have a Levoit 300 by the front door. Levoit 600 in the living room. Austin on the kitchen counter in the corner by the stove. An IqAir in my master. A Levoit 300 in another bedroom. MPR 300 filters for my HVAC.

Austin routinely pays out on prorated filter replacement. They generally last between two and three years, and they weigh 15 pounds and are several inches thick. Unlike the filters in the shark, which are about a half an inch thick and weigh about 6 ounces.

Well, it has to do with media surface area vs. airflow. HVAC filters that are 1" go foul in a couple months in a dusty environment. But the same HVAC, same airflow, and a 6" filter? Yearly replacement. All down to surface area.
