You have an old car that's awesome! I also have an old car. What kind of car do you have? I drive a 94 Mustang Cobra. I have a coway Air Mega 250, and I have been happy with it.

I’m immunocompromised and always have an air purifier (Coway AirMega 150) running next to my lectern. It’s nearly silent on the lowest setting. I also have a larger one at home (250?) that is EXTREMELY loud, so I wouldn’t recommend a big one. The building I teach in is pretty modern, so I have to assume that the ventilation is quite good even though my classroom doesn’t have any exterior windows. I’ve been told many times I’m quiet/soft spoken (despite feeling like I’m always yelling), so masking while teaching is out of the question for me. I also tell my students on the first day of class that I am immunocompromised and therefore that if I do get sick, I am likely to get very sick and be gone for several weeks (sometimes I include the fact that my body literally cannot make antibodies, which is super fun). This info seems to stick with them, as I’ve had many students email me to let me know they’re sick and staying home because they remembered what I said. I am also pleasantly surprised that most students wear a mask for a few days when they return. I never mention masks at all and have never asked for anyone to wear them, fwiw. I also have a couple bottles of hand sanitizer in the room and use it very, very frequently (literally any time I touch a shared surface). I follow the same precautions in my office. I’ve had COVID three times, and two of the three times it was during the summer (I don’t teach summers). The third time I’m 99% sure I got it at a concert. Your mileage may vary, but I feel like my strategies work fine for me and at the very least give me peace of mind.

You seem to understand what you need. You took into account your high ceilings which is good. Most CADR is measured with the average 8 foot ceiling so your numbers are higher which you already posted. Keep in mind CADR is measured at maximum fan speed, so you’ll want a purifier that can deliver CADR over your actual square footage so that way you can run the units at medium speed. Some people run them at max, but most do medium since it’s a tolerable noise level. Since you’ve been on this sub, I assume you know that purifiers are only good to clean the air in the room they’re placed in. They don’t clean air in other rooms because of the way air moves around homes, which isn’t much. I’m no expert and I’m kinda new to purifiers too and there’s much more knowledgeable people on this sub. I can’t speak to other brands, but I like my Coway Airmega 250 that I got. It says it covers up to 930 sq. Ft. And 2 air changes per hour in that amount of space at max speed. I find that the unit may be a little small for the area I’m cleaning which is the living room and kitchen. I keep it positioned between the 2 and it takes longer to clean the air in each room positioned like that vs. being placed in the actual room, but it gets the job done I feel like and I’m happy with it. Not sure how much help that was, but I would look at the Coway Airmega series. Pricy, but good units. I haven’t tried any others but I know air doctor is good but very expensive. Good luck

Air purifiers can’t go into other rooms generally speaking, so you will need multiple purifiers. Whatever room they’re in you can expect the air to be exchanged regularly, but even with a good one in the hallway it would barley exchange the air in the rooms because of the way air circulation works. Having fans going in rooms and pushing air into the hallway to get purified is one solution, but the best solution will be multiple air purifiers. If I were you, I’d get a purifier for the computer room and bedroom. I have a pretty small house and I have a Coway Airmega 250 and I love it. I keep it between my living room and kitchen and it does a good job of purifying the air in those rooms. Sometimes I take it to my bedroom at night. It’s kinda heavy but it’s easy enough to move

I have a AirMega 250 and another cheaper unit in my "cat room" (opposite side of house). I prefer the AirMega in bedroom not as light polluting. I change the filter once a year and its around $80 for the unit.

I have 3x Coway AirMega 250 units (one in each bedroom) and have not had any chemical smell issues at all FWIW. I’m guessing it can depend on the people, as some are more sensitive to certain smells than others.

Coway is really good. Been using that for a while now.

How many sq. ft? Coway Airmega 200M or 250. Winix 5500-2. Yes they will help a lot for allergens and odors, as long as you clean the pre-filter weekly, replace the carbon filter every six months, and replace the HEPA filter every year.

I love my coway airmega 250 - for reference I live in a 750 sq ft apartment with 2 cats. I’ve found all of their models to be really user-friendly and have had it for almost a year without having to replace the larger filter. It is very responsive to current levels (after stove cooking, etc) and the pre filter catches a lot of visible dust. I’d wait for a good deal like Black Friday if you can

Do have the Coway 250 as an option? I got one for $250 open box or refurbished on Amazon. It’s amazing. The sound it makes is very pleasant and it’s easy to clean, and aesthetic. The Coway or 240 is also a good choice and comes in white. The Winix 5500-2 or C535/C545 is also a solid choice and a bit more affordable. I believe Costco has good deals on the C545. Lastly, you could check local marketplaces. I got some Winix, and Blue Air purifiers (the 203 slim, 403, and 503) for a great price.
