Start with diagnosis and load
Filtration, ventilation, and humidity control only work as a system; a single gadget bolted onto a leaky duct system rarely solves a whole-house air problem. Stale air, condensation, or lingering odors usually trace back to some mix of ventilation rate, duct leakage, filtration, and humidity control rather than any single gadget—the fix is almost always a combination, not one product.
Questions for the scope
- What test or measurement identified the problem?
- Is duct sealing or ventilation work part of the plan?
- How does the fix interact with existing heating and cooling?
- What ongoing maintenance does it require?
- What results should be expected, and by when?
Albany building context
Older Albany homes with added insulation for the region's cold winters can trap humidity and pollutants that a leakier nineteenth-century house used to vent on its own. Balancing filtration and ventilation against a tightened envelope is a different problem in a 1910 two-family than in a 1985 Guilderland colonial.
