## Frequently Asked Questions

### What are the most common indoor air quality problems?
The most common issues we see are excessive dust and allergens, high or low humidity, volatile organic compounds from household products, mold spores, and poor ventilation. Modern homes are often sealed tightly for energy efficiency, which can trap pollutants inside. We test your air and recommend targeted solutions.

### What is the difference between an air purifier and an air filter?
Standard air filters in your HVAC system capture larger particles like dust and pet dander. Air purifiers go further by neutralizing smaller contaminants including bacteria, viruses, mold spores, and chemical vapors. Whole-home air purifiers integrate directly into your ductwork and treat all the air circulating through your home.

### Do I need a humidifier or dehumidifier?
In New England, most homes benefit from a whole-home humidifier in winter when indoor air becomes very dry, causing static, cracked skin, and damage to wood floors and furniture. In summer, a dehumidifier can help if your home feels clammy or you notice condensation on windows. We can measure your humidity levels and recommend the right solution.

### How can I tell if my home has poor indoor air quality?
Common signs include persistent allergies or respiratory symptoms that improve when you leave the house, musty or stale odors, visible mold, excessive dust buildup, and condensation on windows. If multiple family members experience headaches, fatigue, or irritated eyes at home, poor air quality could be a contributing factor. We offer indoor air quality assessments to identify the specific issues.
