Nice and easy explanation The filter part really confused me It runs in two different "grains" interwoven with one another for maximum temperature and humidity transfer So much easier to understand now

I live in South Florida, I need hot humid air outside and dry cold air inside Will this magic box do this?

Awesome helpful content thank you
Comment from : @VP411Designs

Do you have any noticeable sound from the vents inside the living space and sound with the unit running from the floor below?
Comment from : @paulbragin5034

Do they actually transfer humidity or is it just that a change in air temp changes the Relative Humidity of the air, due to how much moisture air can hold at a given temp? Genuine question as I don't understand how something can be airtight to stop air mixing but also transfer humidity ✌
Comment from : @northeastcorals

Thank you for this info Do The in flow and out flow ducts need to be insulated ducts or no since the ERV does the temp exchanging too?

Comment from : @keithhupp5995

Comment from : @meowzic

Comment from : @holymoly8718

Comment from : @Commonsensenotsocommon

How would this thing transfer humidity? Sounds unrealistic
Comment from : @timg531

What is air relief valve in this system
Comment from : @arifbabulotapalkatti7643

Oh my gosh thank you for explaining this properly I spent about 20 minutes trying to find a video for someone to watch rather me type it out explaining it how it works So many videos did not explain what a heat recovery unit does when the title says it right in the topic brbrThank youm
Comment from : @ZombielandPB

Wow, this guy goes straight for it I always wonder if the air mixed, now I know Thank you
Comment from : @Chupria

What a good video!
Comment from : @robertouser674

I was looking for a way to heat up my fresh air so the air wasn't so cold going into my return thus making my furnace work harder brAny suggestions? As I don't have my bathroom exhaust piped to my basement like I would need for this type of unit
Comment from : @fortunatedad7695

Who do you call to do this job ?
Comment from : @dianamorales6657

You seem to know what your talking about My problem an old house that feels toxic , inflames nasal passages, it has asbestos insulation, i dont want to live in a toxic house so im thinking air exchanger is the answer? Short of selling my house?

Looks like a magician at a carnival!
Comment from : @darrenchang2907

How do you install one of these?
Comment from : @ahkeen

Thanks, finally found a video that showed how the channels pass without air collide
Comment from : @senjin88

We live in the upper Midwest Hot humid summers and brutal cold winters What of the time do I run my system in each season? More in summer, less in winter??
Comment from : @ralphiewyowyo

Could not have been done easier than this Great video!
Comment from : @jwahrenburgrhahvac4107

Thank you
Comment from : @Maxejage

very nice
Comment from : @joehanna2231

Would I need to install a unit like this to help with moisture on the windows in the winter time? I live in south east Wisconsin The home is only 1 year old We have condensation on the windows when we get up in the morning Humidity levels are upper 40s low 50s in the house during the winter time
Comment from : @_the1mikeod

So,this can work as air purifier?
Comment from : @josegallardo7467

That's some awesome technology
Comment from : @iBringTheRain24

it's a heat exchanger
Comment from : @mjb12141963

It’s actually heat recovery or heat exchange
Comment from : @bell-architects

I am assuming that the "core" works as a filter too and will have to be replace as a consumable? Right?
Comment from : @DaveBoxBG

I wanna pop the smoke too!

Looking to purchase an ERV for a tiny house Can you please recommend a unit? Thanks

I’ve never seen this kind of baby gender reveal before
Comment from : @patsempervirens

Do they really not mix? The color looked differentbrbrAlso, does the core have to be replaced? Is there a secondary filter to remove the outdoor dust and containments? How much does the core cost if so? I know these HRVs can vary quite a lot in size depending on how many square feet they are intended for
Comment from : @Guillotines_For_Globalists

0:59 Are the birds flying into a sunset required to make the core work?
Comment from : @Engineer9736

Comment from : @Soothsayer210

Great idea!!brBut what about mold?
Comment from : @Thomas-ts2gl

Thought this was gonna vid on how to properly operate a gender reveal party
Comment from : @ahassan3557
