Austin Air - Bedroom Machine

Austin Air is the only company I trust. Their purifiers have been used in studies conducted by Johns Hopkins and Cincinnati Pediatrics Hospital (the 2 notable) which is a testimony to their effectiveness. AustinAir products are amongst the best of the best. With the title of being the best comes with the price tag. These are the most expensive air purifiers I have ever come across; but it is 'American Made' and their filters have a 5 year warranty. But it is absolutely not for one looking for budget friendly or anything related to cost friendly. All that being said-- they are a top tier, studied in highly regarded medical institutions as proven and effective air purifiers, look sleek with their box frame on wheels, 3 simple settings. It's what I use for my parents and grandparents(and myself)- can't put a price tag on good health and I know everyone sleeps better with cleaner air. I've gotten them for multiple family members and some have even bought one for their office at work! If you are looking for elite products, search no more, but as I mentioned a few times it is costly. In my opinion, worth every penny. P.S. they have a model for animal owners who deal with shedding as you mentioned. I want to say all of their models contain the military grade HEPA filters in their 6 layer defense, but perhaps the type of filters differs per model so definitely double check whats inside! If you are interested link is below. [https://austinair.com/](https://austinair.com/) \-- My workplace doesn't allow me to bring my personal purifier and has 'Levoit 300 Core' in nearly every room. I believe they are a 6 month(we are constantly replacing ours, at the 5month mark). life filter and I do believe they work quite well. Never any foul odors on our floor or even the kitchen and eating area. Heres the link for what we use where I work and they are surprisingly budget friendly, but still include a quite powerful filter. Link for that is below: [https://levoit.com/products/core300-air-purifier](https://levoit.com/products/core300-air-purifier) So I do think there are alternatives to the elite Austin Air I went with for my home and family. Good luck in your search!

I love my Austin Air bedroom machine. It's pretty expensive though, I think $800 or $900 now. But it also absorbs VOC's which is great for me since I'm chemically sensitive. Most air purifiers don't do much for offgassing.

Same experience and we also use the same model. The filters can last 5 years which does make the initial cost considerably better.

I have 2 of these... family member has MCS and it's very good for smoke. https://austinair.com/shop/the-bedroom-machine/?srsltid=AfmBOoq2_IbM0_orVHoxxlIhon78CRwr9tTN41oKUUnH9yJok_-718Fk

We use the Austin Air bedroom machine in several rooms of our house; it’s the best room-sized unit we’ve used in over thirty years of using air purifier to help manage allergies and asthma. https://austinair.com/shop/the-bedroom-machine/

Austin Air - it’s a tank and made in USA. No fancy controls . Heavy metal frame big fan. Filters last 5 years. Some of their filters can filter chemicals.

I ended up getting an expensive Austin air purifier appropriate for medical use because all the cheaper brands i looked at intentionally or accidentally produce ozone, which is not healthy to breathe.

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. You won’t find a better air purifier. They make surgical room purifiers. This is their consumer versions. Even removes Covid from the air.

An Austin Air and a Coway Airmega 400 are designed for somewhat different uses. Do you want to filter particulates (dander, pollen, PM2.5, smoke particles, etc.), gases/vapors (VOCs, odors, etc.), or both? If you have high levels of both particulates *and* gases/vapors, you really need *two* different types of air purifiers. While there's some particulates filtration, an **Austin Air**—alongside other sorbent media purifier brands like Airpura, AllerAir, or something from IQAir's GC/GCX series—runs at lower airflows and CADRs because of the amount of activated carbon or zeolite. You need to design for ["dwell time" or "residence time"](https://www.emcelfilters.co.uk/carbon-filters-frequently-asked-questions/) for better gaseous removal efficiencies. Sorbent media purifiers are also loud, expensive, and require relative humidity below 60% to present water vapor from being adsorbed. The Austin Air isn't the best choice for reducing particulates in a large room. An FYI up front: air purifiers aren't very good for reducing pet hair or visible dust. Both of these particulates are relatively large and heavy compared to something like PM2.5. Therefore unless either visible dust or hair is very close to the air purifier, both will fall and collect on surfaces. A [DIY Corsi-Rosenthal box](https://engineering.ucdavis.edu/news/science-action-how-build-corsi-rosenthal-box) could give you improved CADR for larger particulates, but some people don't like the homemade look, the noise, or the required floorspace needed. Vacuuming and dusting are still the best methods for controlling pet hair. # Some Calculations The rule of thumb for CADRs is that they should be *at minimum* 2/3 of your room's area. This assumes an 8 feet high ceiling. To figure out CADRs using volume, you need to do a little more arithmetic. Calculate your room's volume. 12 ft. width × 15 ft. length × 18 ft. ceiling = 3,240 cubic feet Then... 3,240 cubic feet ÷ 8 ft. = 405 sq. ft. Finally, 405 sq. ft. ÷ 1.5 = 270 CFM (CADR) **270 CFM is the absolute minimum needed for CADRs.** The **Coway Airmega 400** will be underpowered if you have to filter wildfire smoke. The [Association of Home Appliance Manufacturers (AHAM) recommend a smoke CADR equal to your room's area for wildfire smoke](https://ahamverifide.org/ahams-air-filtration-standards/). Again, room area in this instance assumes a 8 feet high ceiling. In your case, you would need a **smoke CADR of 405 CFM**. 3,240 cubic feet of room's volume ÷ 8 ft. = 405 sq. ft. 405 sq. ft. = 405 smoke CADR for wildfires # Other Considerations In this subreddit, we generally recommend oversizing an air purifier or using multiple air purifiers in a given space. This means you get more clean air faster. With multiple air purifiers, you can increase air circulation. Oversizing is also recommended where higher levels of pollution are persistent. Another issue is sound or noise levels. Despite the specifications, many air purifiers tend to be quite loud on high. Many people don't like the highest setting, but lower settings have lower cleaning performance. Most CADRs are given only on the highest setting. Therefore, oversizing a quiet purifier can make more sense. Or you can buy multiple and run them on the quieter, lower settings. If you do buy one larger or multiple purifiers, be sure to check the power consumption values. Some units are more efficient than others. If your budget allows and you have the floorspace for a dual intake unit, the **Coway Airmega ProX** has high CADRs and would be great for wildfire smoke events. Its sound rating is 23 - 46 dB(A); I don't know how closely sound performance matches the specs. While it's expensive, I've seen prices as low as $619.00 during special Coway sales events.

Austin Air air and other similar air cleaners that are made of metal, not plastic, is an indication that these companies are designed for the most discerning customer. Plastic and glues off-gas VOCs so they are counter productive to removing VOCs. The Austin Air and other serious air cleaners have multiple pounds of activated carbon in their filter, not several ounces that last for a few weeks if the VOC off-gas from the plastic filter housing didn't use up half of it while it sat on a boat from China. The Austin Air has a HEPA filter integrated into the filter cartridge that also includes the activated carbon. Austin Air, E.L. Foust and a few others are next level air cleaners. Did you ever wonder why that HEPA air cleaner didn't take out those fumes or odors? It's because it had a tiny pre-filter impregnated with a few ounces of activated carbon that got used up in a couple weeks.
