ventilation, safe air

[finnstones]

hi everyone, could someone recommend a fresh ahir system (like Nutone) that would be good for keeping the air safe in my 700 sq foot garage?

also, looking for a dehumifider.

to be clear i am trying to solve for the fear of mold , pollutants, etc that build up in a garage even if its envelope is optimzied with the right amount of engineering and insulation for proper air flow.

looking for more advanced ideas - ERV

If you are going to be opening the door once in a while to get a car in and out you will get more ventilation than needed. Unless you are in some type of very terrible environment I cant imagine needing anything more.

Agreed. Is this space incredibly air tight? Like fully spray foamed and a really well sealed garage door?

Short of that, ventilation isn't needed unless you have something specific you need to vent, like fumes

Solving for fear is essentially impossible. No product you can buy is going to be any better, or any worse, than any other.

HRV with a filter.

My thinking is that unless there is something really unusual then a dehumidifier will do the job. Mold almost always starts because of dampness so keeping the garage atmosphere dry will negate that concern.

For garage storage they recommend 4-6 air changes hourly

Recommended Air Change Rates for Different Room Types

Fresh air (make up air) rquirements - or recommended air change rates (ACH) for typical rooms and buildings like auditoriums, kitchens, churches and more.

Dehumidifier the better units have a A.H.A.M. rating. Box store unit usually don't have take rating unless they have one for a crawl space

This member's garage thread https://www.garagejournal.com/forum/threads/woodys-works-garage.263351/
has a section where he put in a HRV system with filters to remove wildfire smoke particles and odor. That ought to do what you're asking. I'm going to do something like that for the house I'm getting built. Maybe the shop as well, if it needs it.
