During wildfire season, are you breathing clean air inside your home?

If you have central air in your home, you are supposed to replace the HVAC filter every 6 months. A standard basic filter costs only a few dollars, and prevents the system from getting clogged with lint, dander and dust. But filters with a higher rating only cost a few dollars more, and are designed to filter out finer smoke and smog particles. Especially during the COVID quarantine, we spend most of our time indoors, waking and sleeping, and it is important for long term health to breath clean air.
Many people never replace their filters, but with the wildfires raging in the West, now is more important a time than ever to throw out the old one, and put it a premium filter that is an investment in your lung health. If you can get your hands on a HEPA portable filter, adding more filtration will only help your overall air quality, but simply changing your HVAC filter is a quick and cheap way to improve your baseline air quality.
The main rating scale is the "MERV" rating, but some companies have their own system. If you buy your filters at Home Depot, they use the "FPR" scale. For filtering out smog and smoke, you want to get a filter that is rated at MERV 13-16, or FPR 9-10.
You can keep up with your current local outdoor air quality using either the Wunderground weather app, or the AirNow app which is managed by the EPA.
