The main purposes of a Heating, Ventilation, and Air-Conditioning (HVAC) system are to help maintain good indoor air quality through adequate ventilation with filtration and provide thermal comfort. Proper air filtration and care for your HVAC system will result in better conditions and air quality for occupants of the building as well as increase the efficiency and longevity of the HVAC system. HVAC Air Filter Efficiency Ratings Placement of air filters within a buildings ventilation system can block airborne particulates that can include, animal dander, pollen, mold spores, bacteria and viruses depending on the Minimum Efficiency Rating Value (MERV) of your air filters. For an HVAC system it is recommended that you use air filters with MERV Rating between 8 and 13. The higher the rating, the more contaminants that will be blocked and therefore will result in better protection of the equipment and building occupants.

At the beginning of the 15-month investigation period, the first filter stages of both HVAC systems were equipped with new unused air filters.

The number of airborne bacteria and molds before and behind the filters were determined simultaneously in 14 days-intervals using 6-stage Andersen cascade impactors. Under relatively dry (< 80% R. H.) and warm (> 12 degrees C) outdoor air conditions air filters led to a marked reduction of airborne microorganism concentrations (bacteria by approximately 70% and molds by > 80%). window ac unit cleanerHowever, during long periods of high relative humidity (> 80% R. H.) a proliferation of bacteria on air filters with subsequent release into the filtered air occurred. types of hvac maintenanceThese microorganisms were mainly smaller than 1.1 microns therefore being part of the respirable fraction. moving outdoor ac unitThe results showed furthermore that one possibility to avoid microbial proliferation is to limit the relative humidity in the area of the air filters to 80% R. H. (mean of 3 days), e.g. by using preheaters in front of air filters in HVAC-systems.PMID: 11556144 DOI: 10.1078/1438-4639-00054 [PubMed - indexed for MEDLINE] Publication TypesEvaluation StudiesResearch Support, Non-U.S. Gov'tMeSH TermsAir Conditioning*Air MovementsAir Pollution

Ensuring that your filter fits properly in your HVAC system means making sure that you have not only the right length and width, but also thickness of your filter. Most standard air filters are 1 - 2 inches in thickness. Whereas media filters are typically 3 to 5 inches in thickness. The best way to measure your air filter size is to get out the measuring tape and measure it directly. Regularly replacing your air filter will help improve the efficiency and longevity of your furnace. A dirty filter in your HVAC system will raise your energy bills.

A dirty filter restricts the air flow into your HVAC systems air handler, causing it to work harder to cool or heat your home. A dirty clogged filter can restrict HVAC airflow and potentially cause problems with the system. They also cease to filter allergens and other particulates out of your air. Dirty, unchanged filters can make your HVAC system fail completely. Repairing a broken HVAC system can end up costing you a pretty penny.Select Your Current Brand for Compatible Filters - we have the best selection of discount furnace filter replacements at the best prices on the web. carry all of the top OEM and aftermarket filter models in a variety of sizesWe have the right discount furnace filters for whatever you need - including custom filters for hard-to-find sizes.
