taking the following steps to protect the interior of your home.
1. Fix Air Leaks. Seal drafty doors, windows, fireplaces and other potential access points for pollutants and allergens. Portable air quality
monitors that provide real-time readings can help locate hard-to-find air leaks.
2. Filter Indoor Air. Use high-efficiency air duct filters to capture PM 2.5 particles and irritants. Fine particle buildup isn’t visible to the
naked eye, so regularly replace used filters. That will often be sufficient in homes with air circulating systems, but If needed, use true HEPA
air quality purifiers (High-Efficiency Particulate Air Filters) in bedrooms and main living areas to continuously circulate and clean indoor air.
3. Monitor Indoor and Outdoor Air Quality. There are many indoor air quality monitors on the market, and outdoor air quality information
can be found on several websites. Most home monitors have smartphone apps that allow us to see both indoor and outdoor information in
one place. Some monitors also have built-in display screens. Very fine particles (PM 2.5) are usually the main pollutants of concern in most
homes. However, airtight homes can build up carbon dioxide levels overnight, so monitors should also track CO2 gas.
Knowing current air quality information can help us make better informed lifestyle choices. However, it’s easy to get confused with
different air quality readings provided by a variety of monitors on Nipomo Mesa. What is most useful to Mesa residents is real-time
information on what’s happening with air quality at any given moment. Fortunately, one of our fellow Mesa residents has made an in-
depth study of public air quality monitoring services and various home particulate matter monitors. His findings are summarized in the
Interpreting Nipomo Mesa Air Quality Data (click below go to each part)
Part 1 explains how to use the available monitors to get information we want.
Part 2 discusses air quality forecasting on the Mesa, and how to identify projected wind
conditions that can create particulate dust events.
Part 3 covers how we can apply this information to protect our indoor door air quality at home.
