Where can I get new filters for the ERV in my condo?

You can typically purchase replacement filters for your condo ERV from the manufacturer or a licensed HVAC contractor. You can try checking the manual or documentation that came with your ERV to determine the exact type of filter you need, as well as the manufacturer's recommendations for replacement frequency. If you don't have the manual or documentation, you can try contacting the manufacturer directly or searching for the model online to find the appropriate replacement filters. 

Additionally, Sychem carries the most common replacement filters for various ERV models and can help you select the right filter for your unit. Some filters are special orders and may have a minimum quantity from the manufacturer.
