There are a number of air filters you can choose from, depending on your individual preference and the type of system you have.
These filters rely on electricity or electronic static. They don’t block airflow to the HVAC equipment, which means it can operate without clogging. They have about a 90 percent efficiency for clean air.
You can purchase these inexpensive filters at any store. The filter traps big dust particles, but they quickly build up and cause airflow problems. Therefore, you’ll want to replace these filters frequently.
These filters are reliable and cost effective, and HVAC professionals use them quite frequently. Since they have a number of fiber layers, contaminants are stopped before they make it all the way through, and airflow isn’t affected.
Pleated air filters are similar to media filters but need to be changed more frequently. Particles land on the cover of these filters, so the particles are trapped without preventing airflow.
These media filters remove dust mites, pollen, pet dander, household allergens and mold spores and are over 99 percent efficient
Activated carbon air filters are used in buildings with heavy smells and odors. The charcoal base helps minimize the need for camouflaging the odors, but they’re not as efficient in removing particles as some other options.
