My apartment still smells like polyurethane after over a month! I have a toddler with respiratory issues, please help
From what you've told us, it sounds like you are trying a number of good ideas to help mitigate the smell and lingering off-gassing but maybe not optimally.


I actually would advise against using bowls of water or vinegar and
adding unnecessary moisture to the air.
You actually want to remove moisture from the air (air conditioners //air dehumidifiers do this), however, if you are in
the colder climates like it sounds like you are, this is not very
pratical and  in the winter months you actually want some humidity
in the air.
You are using space heaters to generate heat, but the windows are open - mother nature is going to win this fight


You actually want to put the space heaters away, in fact, many apartments forbid their use. As long as they provide functioning heat, they can prohibit their use. If it isn't prohibited then use it, but realize they are a safety hazard in more than one way, especially if your fumes are as potent as you suggest.

Just close the windows, get the heat cranked up a little higher, and get a fan to circulate the air. Put water sources away, dry the sink, etc. Don't add unnecessary water to the air. Locate the strongest source of the odor and get the fan circulating air in that room.

Vacate the premises for a few hours, then when you get home, go ahead open two windows, preferrably opposite sides of the space, and put the fan blowing the air directly out for 10-15 minutes. Close the windows, repeat.

I'm not suggesting you do this as an option, but I want you to understand an example of how long a smell can last despite the best of intentions &amp; I only came to this after a few years of frustration:


Need tips, approach, or method(s) to eliminate smell/odor in a closet short of a tear down?


You indicate that you know you can take legal action, but honestly, I'm not so sure that is true. Every area has laws and regulations to follow, but (even if this was subsidized housing), it doesn't sound like the landlord failed to provide livable living space.

If the smell is indeed paint/poly/etc., the instructions&amp;use of most of these products is typically in the span of 1-2 days, so weeks later, its supposed to be safe even if stinky. You can seek out staying at a friends or families, but I wouldn't expect any compensation or recourse from the landlord unless they did something wrong, and its not advisable to throw accusations unless you have a basis.

Keep doing what you are doing, and see if you can pinpoint the issue. Warm air &amp; ventilation will help. If you can locate the source and it isn't paint/poly, then discuss with the landlord. If they are renovating other nearby apartments then request them to wait holdoff spring to use chemicals if at all possible.
