If you’re asking this question, you probably have some sense that you need indoor air quality improvements, but you aren’t sure if air filters are the answer. After all, there already is an air filter in your house—the one that’s on the HVAC cabinet. This is the filter that we recommend you change every one to three months to ensure the heater and AC continue to work at high energy efficiency. Paying attention to this filter is important for indoor comfort.
However, this filter is not there to improve indoor air quality, so if you’re looking for better indoor air quality, yes, you may need an air filter or an air purifier in Houston, TX.
