I can name two! The AustinAir HEPAs are basically a big metal box with a motor. The plastic in it is the squirrel cage fan itself and maybe the speed dial cover? Same for the SmarterHEPA (outside the US Smart Air) Blast and Blast Mini models. They again are a big metal box with close to zero plastic outside the fan itself. Of course even the motor will have plastic covering the wires or things like that. And the power cord has a plastic coating so nothing these days will be 100% plastic free but these two models are very close. Also both of them are really great HEPA filters! Basically no ‘features’ to either, just a big box with a fan and a speed dial. I had the AustinAir for like 30 years running 24/7.

Second this - Austin uses minimal plastics. Just the fan blades, knob, and wires.

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.

Best of the best would be really any product from the company Austin Air Passable would be like a winix 5510-5520 The most important thing here is that it has a decent amount of carbon in it, carbon being the only thing that actually removes the odor. Austin has the most carbon, winix doesn’t have a ton but it’s passable and a lot more than most of the ones you can get at Walmart. Either way though your roomie like smoking next to the air purifier every time specifically is something I’d recommend, pot smell has a habit of spreading out pretty quickly and then it becomes a question of how quickly can your purifier get the entire apartment.

I have had my Austin, IQAir, Honeywell and Whirlpool machines for as much as \~20 years and have had no problems with filter replacements.

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