It’s important to install a high quality air filter on the HVAC system in your home, since inexpensive fiberglass air filters only capture 10% to 15% of airborne particles. Look for filters that contain carbon, are electrostatically charged, or have a HEPA rating which can remove up to 99% of airborne pollutants.

If your heating and cooling system gets clogged with excessive dirt, it will have to run longer to heat or cool the same amount of space. It will cost you more money to use and contribute more greenhouse gas emissions. Your best defense against this is a good quality air filter. But before you buy those 99 cent disposable fiberglass filters, watch how much of this dirt falls right through it. These things will only remove about 10-15% of the dirt, dust, pollen and other airborne pollutants that are in the air. When you consider that the average person breathes in about two gallons of air every minute, just think of what else is going in to your lungs! Spend a little extra money for a quality filter like carbon, HEPA or one with electrostatically-charged fibers. These types can remove up to 99% of pollutants, which is truly a breath of fresh air.

  1. Also consider a whole home air cleaner that is continuously high-performing such as those with the newer, non-metal technology that is much easier to maintain (no wires, etc. to clean) and that also gets those tiny airborne particles (RSPs) + can be bolted on most any home hvac system + does not emit ozone and requires only one to two simply filter changes a year – taking under 10 minutes total. For a clumsy DIYer like me these are vital considerations

  2. There is only 1 filter in the a.c. In whole house forced air system – the 16 x20 return vent inside the house allows air to directly to into duct work. Does this sound proper? Would efficiency improve by adding a filter in return vent?

  3. Our condominium association needs a recommendation for air filters we can use with our vents into the kitchens and bathrooms. We need them to filter the particulate matter as well as the unwelcome smells that emanate from other units that share a common air shaft. Our vents are roughly 5″ (H) x 10″ (W). Can you recommend such filters?

    • Hi, Elizabeth,

      Danny says, “I would say generally a charcoal-based filter works the best for the elimination of odors like you mentioned. I would check with The 3M Company, which offers almost any filter you can imagine.

      Good luck!”
