AirMedic Pro 6

Most home-grade pufifiers are geared towards removing particulates. Such purifiers don't remove odors unless they are specialized units with large carbon canisters. The ones you are considering will move the odors around, and this may help dissipate it (just as any fan would), but they do not contain nearly enough carbon to remove odors. While these products claim to remove odors, these claims are, at best, *heavily* inflated. An example of a unit that will remove odors (and volatile organic compounds, in general) is the AllerAir AirMedic 6 with a 40lb carbon canister filter. This is a large, expensive, loud unit, that uses a lot of electricity, as is the case with all purifiers that can effectively remove odors (as they have to move air through a deep carbon bed, which requires a powerful motor to do so).

Mine is out of reach for most people, but im about to have 3u3 in the middle of wildfire season, so i had to invest in what actually works on the smoke. Allerair Airmedic Pro 6. They are *very* expensive. But wildfire smoke requires at minimum 20lbs of carbon. Mine has 34lbs. For a normal, everyday animal hair/allergens model, Oransi Airmend is great.

AllerAir. They come at a variety of sizes and price points but all have the same basic design. Even their smaller model does a good job. They can be pricey and it's an investment. They do not make pretty, electronic units with digital readouts or app connections. This is a metal housing (painted white) with a very large, heavy filter inside, and a motor with a mechanical fully adjustable rotating speed dial. I've had good luck with longevity of the filters and I am still on my original filter after a few years. The large, heavy filters take care of some toxic gases as well as your typical everyday allergens, dust, and pollutants. It's a different breed of filter than you get from Winix and Coway and the others who make units with HEPA filters. Their major competitor is Austin Air. The disadvantage of Austin Air is their motor only has three speeds and the medium and high speeds are loud. I had terrible luck with Austin Air filters not lasting long.

For best VOC removal, such as mycotoxins, you need a lot of absorbent media. Checkout Airpura, Allerair, Austin, IQAir. All are in the $1k range. I'm unsure whether any filter will eliminate mold sensitivities. Did see an improvement when upgraded my Austins with Immunity Machine filters but molds still aren't totally controlled. There are clinics which can treat mycotoxin sensitivities. Can be quite expensive.

Allerair is excellent as well and cheaper than many if not all of the others with as good or equal in build and performance.  

I have a couple allerair I have been happy with. They have some of the largest carbon filters, work great for smoke and pet odors. I have one in a bedroom with a cat box. If the cat uses it at night the smell is gone in minutes. Allerair, airpura, Austin air are similar units. Metal cabinet, a switch, a fan and a filter. Very little to go wrong.

Check out Allerair they have models with large carbon filters specifically for wild fire smoke. I believe they are also made in Canada. Airpura is another similar one not cheap but I’m happy with the ones I have. I’m in Wisconsin and we have gotten a lot of smoke this year and don’t smell anything inside.

AirOasis is really good. It's one of the few purifiers that I have felt a noticeable difference in the air, despite trying almost every brand on the market now. I've been very impressed with their customer service also. If you're in a high VOC environment, you need a purifier with a very thick carbon bed in the filter like some Austin, AllerAir, and Airpura models do. I have an AllerAir in addition to the AirOasis unit for this reason.
