I want the factory number

You graphic s says put Merv 13 on the supply side. The earlier graphic has the word "supply" on the left. Then in answer to a question by another viewer you say put the Merv 13 on the right. Which is it? It seems like this is one of the key points of the whole video, but you don't say in your narration where to put which filter and your graphics which purport to answer this are small, brief, ambiguous and contradicted by your reply to a question in one of the comments.

Why does it matter which side gets the finer filter? Seems like the air you are going to breathe passes through both before it gets to you. I would think you would want it to go through the less fine filter first. But you want it to go through the finer filter first? Why?

For the ComfoQ600, your website sells the MERV-15 and carbon filters, the MERV filter has an orientation label on the filter itself, but the carbon filter has no orientation label. Could you please post a video or let us know what is the proper orientation and order to install the two filters together in the comfowell box? Thanks!

Can you clarify which filter should go on which side? The pics that pop up in the video are not clear. At 25 seconds the pic shows Return Air and Supply Air on the left side of the unit and the Exhaust Air and Outdoor Air on the right side. Then at 50 seconds the pic of the filters shows Merv 13 Supply Side and Merv 7/8 Return Side. The earlier pic shows Supply and Return Side are both on the left side of the unit. If the red filter is Merv 13 does that mean it goes on the left side that handles the interior air?

Distributeur en France svp !

Great video. Great efficient tech. What is with the "Strict 1/2" water lines" to and from the heat pump unit. What problems would using 3/4 line cause?

Yes we have used this on a passive house in Rhode Island and did not require glue, use a fastener with a very wide head designed specifically for installing insulation boards. as for Jacques comments below it depends on the grade (insulation or façade grade) used. typical saw blades used for fine finish cutting (more teeth the better) will be fine to cut and trim with and any professional should not have an issue with this process. you can also select what size boards you desire for greater efficiency of less waste. Cork is a FANTASTIC carbon negative product that is resistant to rot, mold, and pests/ insects. Red List Free with ZERO additives or chemicals used in fabrication.

I have the Zehnder Q450 as well as the combi Sanden system heating water for a concrete slab as well as regular use. I am extremely pleased with these products and will achieve a net zero rating once my solar panels are installed.

thanks bro. this helped very much. I am American but living in Switzerland. The instructions I have are in German French or Italian. Your video was in beautiful, understandable ENGLISH. Thanks again. Ron Guida

Anyone know if the boards can be screwed to battening timber on a vaulted ceiling without the need for glue?

Has anyone used this product in the USA

Can you come to Waterloo, Ontario? I am super interested in the Sanden system!

Great explanation about CO2 sink effect of EXPANDED CORK, one of the many advantages of installing a product 100% natural, recyclable and renewable

What length of screw was used in this video? 7.9" ?

Hello, Thanks for posting. I am about to do a similar project. Now that 7 years has passed, how has the system held up?

board glass insulation would do the same job with less hassle

Excellent!
