Questions we hear
Before you book.
How can I reduce wildfire smoke indoors?
Keep windows closed, use a high-efficiency filter such as MERV 13 if your system can handle the airflow, and add a portable HEPA air cleaner for the rooms you use most. Not every system can take a denser filter, so have it checked first.
What indoor humidity should I aim for?
Between 30% and 50% is the range the EPA recommends. Drier air irritates skin and airways, and damper air encourages mold and dust mites. Whole-home humidifiers and dehumidifiers hold that range without a separate unit in every room.
Are air purifiers safe?
Most are, but avoid ozone generators. Ozone irritates the lungs, and California restricts the sale of air cleaners that emit too much of it. Look for models certified by the California Air Resources Board.
How often should I change my HVAC filter?
Every one to three months for most homes, and more often with pets, allergies or during smoke season. A clogged filter cuts airflow, strains the system and raises your energy bill.
