Keeping an air purifier running efficiently requires me to keep all the windows closed which negatively effects the temperature in my apartment. Is it worth the trade off?

Without ventilation, you are increasing CO2 to over 1000 ppm doing that, which as the study points out is bad in itself.

I was wondering about similar things a while back. I don't know if there are any easy options, but if you were, say, looking to do a custom house build, it seems that a passive house with mechanical ventilation heat recovery (MVHR), or alternatively a positive pressure system, would be ideal for indoor air quality. In either case you are getting a steady supply of purified, low-CO2 air to breathe.

Keeping plants in your house reduces CO2 levels and removes pollutants, perhaps try that.
