Winter is often the trouble time for homes when it comes to indoor air quality. A house needs proper insulation to keep heating systems from wasting energy because of drafts. But that also means stuffy air filled with plenty of unwanted particles swarming through the house. Air filters (not the filter in the HVAC system, which isn’t for air quality) are one of the best ways to solve this problem.
Here’s the tricky part, however: there is no such thing one-size-fits-all air filter. Air filters have different efficiencies, and going for the strongest efficiency you can find for air filters is a bad idea!
