N95s are useful against wildfire smoke, but elastomeric respirators with particle and gas filter cartridges can be even better in the long term.

People should use what they have available to them if they can't get out of the smokey area. But the government should definitely be working to get first responders and people who are stuck in the areas with unhealthy wildfire smoke the best masks possible. And that includes elastomeric respirators which have better dimensional stability and can also filter gases in a way that n95s do not. 

Regardless of what kind of mask you have, you'll get the best performance from it if it seals well against your face. If you're using an n95, or similar mask, please make sure the nose wire is conformed to your nose bridge as well as possible to reduce the amount of unfiltered air that gets into the mask by going around the filter.
