How to select the correct HRV filter as there are 2 sizes

Be sure to to select the correct HRV filter as there are two sizes.

"Generation 1" is for the older steel box HRV

"Generation 2" is for the newer plastic box HRV

In 2014 HRV introduced the new Plastic box HRV which due to being plastic has a thicker wall thickness.

This meant the HRV filters didn't fit

the supercell generation 2 will fit like a glove into the newer HRV.
