Third party airsense HRV filter media that is f8 grade. 
This is the media only not the whole filter box you can use your old one. 
This is compatible for the new airsense system you need to pull the clips out from the ends then pull the white clips out and replace media. Doesn’t matter if clips don’t push flush all the way back down it will still fit just push down as much as can. 
You will need the key to reset the filter light also.
If you like to send me your old one and I can change for you for additional cost send me a email to find out more.
