HVAC means Heating, Ventilating and Air Conditioning. There are different types of air filters in HVAC field now-a-days. These filters are used to keep parts of the indoor systems from clogging in dust, dirt, debris and other foreign materials. They are also known as Furnace Filters. Following is a list of particulars that you might not know about HVAC filters;
1. Primary Purpose of HVAC Filters is to Protect the Equipment: HVAC Filters are installed with the intention of keeping our environment clean and clear. But the primary purpose of HVAC filters is to protect your equipment in which these are installed. They enhance the overall performance of your equipment by absorbing dirt and other foreign materials.
2. Buy Electrostatic HVAC Filters: Always go for high efficiency electrostatic if anyone in your home smokes. It helps you with your allergies or asthma too. Also opt for this type of HVAC filterif you have pets at your home.
3. Filter Types:
a. Mechanical Filters: They remove air borne pollutants. They capture them on a filter medium like window screen or a laundry dryer filter. They are the cheapest and disposable.
b. Electrical Filters: They attract and trap debris like a dirt magnet.
4. Always Get a HVAC Filter that Requires Less Changing:if you are not very much in to cleaning routine then you must always opt for a HVAC filter that requires less changing and can maintain their efficiency over a longer period of time.
5. Filters Work Harder in Summers:Many models have blower motors that work harder in summer than in winter. Clogged machinery can result in furnace repair which can cost you heavy fee of a HVAC technician. Therefore, HVAC filters must be changed in summers frequently.use link from http://www.achrnews.com/articles/132236-hepa-filters-market-to-reach—billion-in–
6. Every Filter Has a MERV Rating: MERV ratings are used to check the efficiency of a furnace filter. It ranges from 1 i.e. least efficient to 16 i.e. most efficient. You must always opt for a model with higher MERV rating. Medium efficiency filters that range from 7 to 12 on MERV scale are the best furnace filters to keep a balance between pollutants removal and filter cost. It will also tell you the particulate size it captures and thus allows you to control your indoor environment.
7. Dirty HVAC Filters Causes Efficiency Hurdles: One thing we most often forget about furnace filters is that they, when dirty, causes inefficiency in equipments. Because dusty filters cannot absorb more dirt and all of the dust, dirt and foreign particles go directly into the equipment. As a result, the inner machinery gets clogged. Thus, the overall efficiency of the equipment is influenced negatively.
8. HEPA Filters: These are High Efficiency Particulate Air Filters. They are also known as Ultraviolet Filters. They are highly efficient and block up to 99.97% of all air particles with a size of 0.3 micron or larger. If you are keenly interested in a totally clean environment then HEPA filters are the best furnace filters for your home.
