Update: My landlord served me a 3 day notice to cure violation or move out over keeping my window open. It's not on my lease. It's not a violation. (lemmy.ml)

Just to piggyback off this comment a bit (since I'm not sure I've ever rented anywhere with MERV 13+ filters). Try making a Corsi–Rosenthal Box with a box fan and 4 air filters. This might be beyond your price range since MERV13 filters aren't the cheapest in the world when you have to buy 4 of them, but I've been using mine for years and they work REALLY well. My PM2.5 sensor is consistently on "0" unless I'm cooking.

    While Corsi boxes do work, I personally find that just using a single thicker 4" filter taped to the back of a fan works better, as it takes up a smaller footprint and allows you to direct the air flow at something other than the ceiling. The thicker filter is much, much less restrictive than a 1" filter due to the increased surface area. The thick ones (20x20x4") cost about $28 on ebay, and will last a very long time before needing to be replaced.
