Oransi - TrueCarbon™ 200C

If you're only worried about the smell, not particulate matter, the Oransi TrueCarbon has a lot more odour-absorbing carbon. 3.2lbs. It's more expensive, but you really need a lot of carbon to reduce smells. And even that, frankly, is not going to resolve the issue entirely. As well, you can get two purifiers, one that's good for odours, one that's better for particulates. You should consider other odour-reducing methods too. You can run an ozone machine periodically. You do this when you're not home, because ozone is harmful to humans. But it will actually destroy the molecules causing the smell. Washing your clothes and bed-clothes (and pillows and blankets) with a specifically odour-reducing detergent will help. You can get a mattress protector to keep the smell out of your mattress too. The most efficient way to tackle the problem is to prevent the smells from getting into your space. If you have a window that's away from your two problem areas, you can put a fan in that window pointing inward, and another fan in the problem area pointing outside. I recall reading some experiments that people have done, you can do some googling and turn up useful tips.

Yeah you definitely want carbon. HEPA is not necessary in your case and not in almost any purifier. It's usually "good enough" but not as good as non hepa almost always. My vote would be on the starkvind purely from a cost to space standpoint as effectively it takes up "no" space. But if the smell is that bad you may want to consider something like the Oransi Truecarbon Of course if you can ventilate, blow the air away, remove/cover the flooring, or bake out the VOCs(or some combo of those) that's much preferred

Hello, I saw your chat messages but thought I'd add on here. Cooking odors are always tricky. With many cooking methods and ingredients, you're likely producing oily aerosols. If you've used a kitchen with inadequate ventilation (e.g., no exhaust hood), you know how sticky and gross cabinet tops or other surfaces can be. Any air purifier running within the kitchen is also going to catch these aerosols which can form a residue on the outside grill, pre-filters, and mechanical filtration media. This can lead to high frequency filter changes and unit cleaning. Sorbent media like activated carbon, activated alumina, and synthetic zeolites can adsorb or possibly catalyze the destruction of certain gaseous compounds, but removal efficiency depends on the gases being produced. For instance, there's an entire article reviewing the VOCs produced by cooking meat by general chemical classes of alcohol, aldehyde, carboxylic acid, ester, ketone, furan, and furanone.^(1) Aldehydes, as an example, require specially treated activated carbon to increase otherwise middling removal efficiencies. Additionally, there's usually quite a lot of moisture produced on the cooktop (e.g., open pot boiling and frying). Sorbent media really requires lower relative humidity, as moisture can be adsorbed and prematurely saturate something like activated carbon. If possible, can you sweet talk your landlord into installing a more powerful ventilation hood? Especially one that exhausts to the outdoors if possible. Do you have a kitchen window and if so, can you fit a box fan in it? This may not be a great solution if the temperature isn't pleasant, but it would be cheaper. Oransi TrueCarbon would be a budget purifier solution as it has 3.2 lbs. of potassium permanganate sprayed activated carbon. But I'm quite sure there are no particulate filters—not even a pre-filter—on the Oransi TrueCarbon line. There's just a grill as far as I know. So it could get grossly sticky on the carbon filter itself. ^(1)Study is Bleicher et al., "Formation and Analysis of Volatile and Odor Compounds in Meat—A Review", in *Molecules*, (2022).

We have a few models: Oransi mod+ for large spaces, Winix 5500 for a bedroom and Oransi TrueCarbon for smoke odor removal. Have tried some others and like these the best.

Nothing on your list is going to help with cigarette odor. Sorry. You need many pounds of carbon for that. You could try an Oransi TrueCarbon but you might need a carbon heavy unit and those start around $750.

Under $500 you have exactly one odor purifier and that’s the Oransi TrueCarbon. There are others with a little carbon but not enough to mitigate cooking or pet odors.
