Measured Air
Service 04 · Fresh Air / Makeup Air

Filtration cleans the air. Ventilation replaces it.

A purifier can't lower CO₂, clear stale odors, or feed a furnace that's starving for air. Sometimes the fix isn't scrubbing the air you have, it's bringing in more, balanced, filtered, and smart enough to pull back when the valley fills with smoke.

Ventilation · CO₂ right now
1,180ppm Stuffy
Fresh Target 800 Stuffy

A purifier won't move this number. Only fresh air does. We bring it in on purpose, filtered and balanced.

Why ventilation, not just filtration

Some problems you can't filter your way out of.

Filters can't remove CO₂

A purifier won't lower carbon dioxide or stale odors. Only fresh air does that. We bring it in on purpose, filtered and balanced.

Tight homes need makeup air

Range hoods, dryers, and fireplaces pull air from somewhere. Without makeup air, that somewhere is often your chimney, backwards.

Fresh, not smoky

Bringing in outdoor air shouldn't mean bringing in smoke. We filter and control the intake so you get fresh without the haze.

What we handle

Bringing in the right amount of fresh air, at the right time, without the smoke.

  • High CO₂

    Stuffy bedrooms and packed rooms that need real fresh air, not another fan.

  • Makeup air

    Replacing what big range hoods, dryers, and fireplaces pull out of the house.

  • Balanced ventilation

    Supply and exhaust that work together instead of fighting each other.

  • Combustion safety

    Backdraft risk from furnaces, water heaters, and fireplaces in tight homes.

  • Smoke-aware intake

    Fresh-air settings that pull back automatically when outdoor air turns bad.

  • Heat recovery

    ERV and HRV options that ventilate without throwing away your comfort.

How ventilation works with us

Find the gap, size the air, prove the balance.

  1. Find the gap

    We measure CO₂, pressure, and exhaust to see where fresh air is missing and where the house is pulling it from.

  2. Size the air

    We calculate how much outdoor air the space actually needs, and when, instead of guessing at a fan size.

  3. Bring it in clean

    We design filtered, controlled intake, with heat recovery where it fits, so fresh air does not cost you comfort.

  4. Verify balance

    We re-check CO₂ and pressure to confirm the space breathes properly and nothing backdrafts.
