Modern houses and apartments are built to be airtight for greater heating and cooling efficiency . They are so air tight , however , that new air circulates back into house very slowly it may take hours for the air in new house to recycle itself. This creates not only stale air but a build up of indoor air pollutants not need to be cleaned the air duct vents and main return. These pollutants include irritants such as dust, smoke, mold spores, pollen, and animal dander, apply air scrubbers over 4 hour period to remove all
debris inside vents and thermal fogger to eliminate mold spore in vents . Things that can cause health problems bother lungs but clog up heating and cooling systems, computers , and other electronics equipment – but also more serious environmental hazards such as the outgassing of formaldehyde from construction materials .
Several devices are available to clean air of tightly-sealed house. Forced-air cooling and heating systems can have electronics filters installed right inside the HVAC ducts. If you don t have these systems , buy a portable air cleaner with HEPA filter. Developed by the U.S. Atomic Energy Commission to remove almost all airborne particles. HEPA ( High Efficiency particulate-arresting) filters are widely used in hospitals. A true HEPA filter removes 99.97 percent of particles as small as 0.3 micron ( a micron is one-millionth of a meter; the period at the end of this sentence is several hundred microns across) An ultra HEPA, or ULPA, filter removes particles as small as .1 micron . HEPA filters need to be replaced periodically, typically every one to three years .
Cleaners help prevention
Electronic air filters are built into the ducts near your furnace . ) A unit can be added to existing systems by modifying the ducts) A typical electronic cleaner has a pre filter that is similar to a standard furnace filter . It traps large dust particles and can be removed for cleaning. Next in line is one or two metal boxes (also removable for cleaning) containing thin metal plates. Particles in the airflow, typically in the return duct, are positively charged on their way to the plates, The plates themselves are negatively charged to attract the particles , which are driven against the plate walls as they pass through the system. These appliances can remove over 90 percent of the most airborne pollutants, including pollen and smoke particles. The drawing back is that larger particles hitting the plates can make an annoying sound like and outdoor bug-zapper .
Things to do change the filters every 6 months , wipe down daily , bi-weekly , monthly cleaning reduce debris , particles like base boards, floors, and vacuum carpet . Have a HVAC tech come out seasonally to change over filters and maintain HVAC system for optimal cleaning levels and health.
