Stinky pain cave and HVAC planning
Quote | Reply
Any advice in regards to HVAC planning for a new house with a pain cave? My current workout space is in the garage and not connected to the houses HVAC. It stinks/has stale air and I don't want to stink up the new house by circulating that air throughout the house. Is this an issue or have others found the typical HVAC filters well enough?

I have a zoned system between my basement and main floor. No issues with stinky air going upstairs. Basement can smell when I am working out, but it quickly dissipates after the workout.

This is a non-issue. I use an extra bedroom as my pain cave and the temperature and smell normalizes within 10 mins after any session.

Get a Mitsubishi split AC

We use them for our IT rooms and the temp in those rooms gets down to the low 60's

Do one for your bedroom also and sleep in super comfort.

You sure you're not getting olfactory fatigue?

I would say calculate at least 12 air exchanges per hour and give a 20 or 30 percent buffer for vent pipe lengths or restricted air flow. but you for sure need a exhaust fan. for sure.

If you're seriously concerned with odor, and I mean like absolutely can't have it, then in the room where the pain cave is put a split AC unit like someone said, Mitsubishi or whatever, not ducted just a unit in the room with a condenser outside, AND put a small exhaust fan that exhausts outside. Something like you'd have in a bathroom, maybe 100 to 200 CFM max. Put it on a switch so on the extra stinky days you have it on for a while after but can turn it off once the room is de-stunk You'll theoretically pull some air from the adjacent space (assuming a hallway or whatever the door to the pain cave opens up to) so there's no way the odor leaves that room while the fan is on. You're wasting some energy probably and depending on how your whole house is set up maybe pulling more of a negative than you want, but if you're just talking a small toilet exhaust fan over an entire house you're most likely ok.

Just a suggestion but you can always get a HVAC 3m Filtrete carbon filter to help with odors. They offer better filters, but the best one with their odor reduction is probably the following.
