Can I install additional ventilation in my condo unit?

In most cases, it is not recommended to install additional ventilation in your condo unit without first consulting with your condo building's management or condo corporation. 

Condo buildings are designed and built to specific ventilation standards and altering the ventilation system can have negative impacts on the building's overall air quality, ventilation, and balance. In addition, any changes made to the ventilation system may require approval from the building management or condo corporation, and may require permits from the city.  

However, there are other ways to improve the air quality in your condo unit. For example, you can use indoor air purifiers or ventilation fans, keep your unit clean and free of dust and allergens, and regularly change your HVAC air filters.  

If you have concerns about the ventilation in your condo unit, it is recommended to speak with your building management or condo corporation and ask for guidance on the best course of action. They may be able to provide suggestions or solutions that are in line with the building's ventilation system and standards.
