How can I improve indoor air quality in my home?

Key steps include upgrading to MERV 13 filters, installing UV germicidal lights, adding a whole-home air purifier, controlling humidity (30-50%), ensuring proper ventilation, and scheduling regular duct cleaning.

What MERV rating filter should I use?

For most Houston homes, MERV 11-13 filters provide excellent air quality without restricting airflow. MERV 13 captures 85%+ of particles including pollen, mold spores, and fine dust. Check that your HVAC system can handle higher MERV ratings.

Do UV lights in HVAC systems really work?

Yes, UV-C germicidal lights installed in the air handler kill 99.9% of mold, bacteria, and viruses that pass through your HVAC system. They're especially effective in Kingwood's humid climate where mold growth is common.
