The U.S. EPA reports that indoor air can be many times more polluted than outdoor air, making air purification systems a must in some homes. Newer homes tend to be tightly constructed and have far fewer air leaks, which can concentrate the numerous pollutants that contaminate the air. Because air quality has become a greater health concern in recent years, new HVAC technologies are available to help you improve your home’s air. They include:
- Portable air cleaners. These devices will clean the air in a limited space, and require a good deal of maintenance, along with space in a room. Some of them create ozone, a known respiratory irritant.
- Whole-house air cleaners. These systems connect to your HVAC system and will improve the air quality throughout your home. They normally include high-efficiency filters that trap all but the smallest particles, including:
- Dust mite waste;
- Pet dander;
- Viruses and bacteria;
- Mold; and
- Larger tobacco smoke particles.
Central air purification systems provide these advantages:
- Reduced allergic or asthmatic reactions.
- Lower airborne viral and bacterial contamination.
- Fewer offending particulates and mold spores inside the ductwork.
- More efficient heating and cooling because HVAC components stay cleaner.
The type of filter inside the air purification system dictates how many particles the system will trap. HEPA (high efficiency particulate air) filters trap the smallest particulates, including tobacco smoke. These filters have a MERV (minimum efficiency reporting value) from 17 to 20, while other air purifiers may use less dense materials and have lower MERV ratings (though still relatively high). Higher MERV ratings indicate more particle entrapment, good in environments where allergies or asthma are serious.
When you have a central air cleaner, you’ll have to change the filter based on the manufacturer’s recommendations. If the filter gets too clogged, it will slow the operation of your HVAC system, increasing energy consumption.
