HVAC Air Cleaning
Pollution is a major health risk that can cause numerous health problems, especially problems relating to respiration. Outdoor pollution is a risk to health in some areas, but indoor pollution is a risk to health in all homes. Weather conditions can result in a desire to keep all windows closed and prevent good ventilation, which allows indoor pollutants to worsen over time. An HVAC air cleaning unit exchanges the pollution inside the home for fresh, clean air. Does this Spark an idea?

1
Look at the building and the HVAC system installed in the building and determine the building's filtering needs. A large office building will need a higher efficiency air cleaning filter installed in the HVAC system than a personal residence. Personal residences typically need simple in-duct air filters to remove allergens like mold, dust and pet dander.

Look at various air filters available for an in-duct HVAC system. There are several filters available that range from very high efficiency models to filters that can filter most minor allergens but cannot filter large particles. Look at the Minimum Efficiency Reporting Value, or MERV, score to determine which filters are high efficiency and which are lower. MERV scores near 20 are very high scores and MERV scores near 1 are low.

Buy an in-duct filter that meets the air cleaning needs of the building. A high-efficiency, in-duct filter for personal residences should have a MERV score between 7 and 13, depending on the HVAC system and the size filters that can fit. Larger buildings and commercial properties, which have larger HVAC systems, can use the highest efficiency filters ranging between 17 and 20 on the MERV score scale.

Clean the filter regularly according to the instructions of the specific in-duct filter. A filter is ineffective when particles build up, so regularly cleaning is a must for clean air.
