I have an air purifier that has a hepa filter and a UV C bulb that sterilizes the air passing though it, like in hospitals. No ozone. Seems to work well, bought on Amazon. https://a.co/d/0gog59cP

In addition to the cleaning suggestions and talking to your landlord about the HVAC system needing service, I would get a couple of good HEPA air filters that you can run non-stop. I have 4 of these https://a.co/d/85daMOr and they do a great job of getting dust and debris out of the air before it can settle. It won’t solve the problem, but it will help. The filters are easy to change as well.

Look under the cabinets where the pipes come in and see if there’s gaps. I had an apartment years ago where the smell from the lower unit was coming in through there. They put some spray foam in to block it off and it helped immensely. I have germ guardian purifiers with pet filters that I’ve had for years and they help a lot with allergens and I also smoke cannabis and it helps with that too (I live in a house so it’s just me, but it helps circulate the air and get cooking smells and cat dander out of the air too).

GermGuardian 743 Sq. ft. Tower Air Purifier with HEPA Pure Filter with activated carbon. It's pretty great!

No I don't hear anything except soft white noise. I love it. I think it was around $70 on Walmart

With that in mind a germ guardian tower is probably the most affordable good option. Whatever you buy should have UVC light built in to degrade mycotoxins, “plasmawave” or “bipolar ionizer” is also an acceptable alternative just make sure it’s California CARB certified. Stay away from classic ionizer/ozone

I do. I have 3 school aged kids aka plague carriers. We have Germ Guardian UV-C plus HEPA filters in each room. It greatly cuts down on kids reinfecting each other and us parents. They also collect cat hair pretty well. The Germ Guardians were $98 each and 4pack of replacement filters is $30. Saving one doctor visit for the 3 kids covers buying a unit.

Blues air or GermGuardian with UV. I’ve had mine for years and it’s been great

They don't really work if you have an active infestation. Ive got 4 lg ones in an 800sq ft house and I swear they do almost nothing. We even have this electrostatic filter in the hvac and still I've get systems when the doors close or the AC goes on. I have 2x airmega 200s, germ guardian rated for 900 sq ft, coway with uv rated for 600 sq ft. 2 upstairs and one down. If I were you id try to build the biggest Rosenthal filter or several as they don't get down hall ways or around stairs, etc. The think I don't like is they really tank your electric bill and are very noisy, as they have to stay on high mode.
