Utilizing air filters is essential. All dirt and trash are contained within. Consequently, system breakdowns and unnecessary repairs are avoided. Low-performance air filters drain resources, incur extra maintenance expenses, and damage your equipment. Not every inexpensive air filter is a waste of money. It is more crucial to consider the entire cost of ownership than the initial cost when purchasing an air filter. Here is guidance on how to get the best air filter. Discovering the lifespan of your filter is a simple method to save money.
HVAC filters; Energy efficient
There are different types of filters;
High-efficiency pleated filters
These are Standard-sized HVAC filters. They are inexpensive and straightforward to install, and high-efficiency pleated filters are a popular option. A good example is the standard capacity 8×36×1 air filter which is more effective than most air filters. Accordion-folded media enhance the surface area of pleated filters and reduce air resistance. One of the pros of using high-efficiency pleated filters is they are ecologically friendly and exceptionally energy-efficient. Due to their low airflow resistance, pleated filters are suited for applications requiring high efficiency and low-pressure drop. They are primarily used in Private, public, institutional, government, and medical institutions are included, but not limited to.
Rigid cell filters
They are usually in a box-style format with fiberglass or a synthetic substance as the medium utilized in rigid cell filters. Fiberglass is inferior to composite materials because the fibers spread in the wind. The depth of strict cell filters ranges from 6 to 12 inches, with metal or plastic frames. The Stiff cell filters with galvanized steel frames and diagonal supports are durable and VAV-compatible. They are primarily used in HVAC, Air Conditioning, Ventilation, Humidity, Clean Rooms, Food Processing, and Manufacturing.
Pocket filters
The pockets of plastic or steel pocket filters are filled with fiberglass or synthetic material. The width of sewn or ultrasonically welded sections ranges from 10 to 36 inches—maximum efficiency rating with 95 percent relative humidity. In the pharmaceutical and healthcare industries, pocket filters may be final or pre-filters. The pressure reduction with pocket filters is negligible, and their lifespan is 8,000 hours. Their application is institutional primarily, Medical, Public, and Industrial environments.
Hepa filters
HEPA filters are utilized when hazardous particles from microorganisms, chemicals, or radiation are a worry. A HEPA filter has been tested and verified effective by the IEST and UL, in addition to meeting the Department of Energy’s criteria. HEPA filters remove 99.97% to 99.99% of particles as small as 0.3 micrometers.HEPA filters improve with continued use. More soiled filters are more effective at catching tiny particles. Particles more significant than the 0.3-micron gaps between the filter’s fibers anchor themselves into the thread. If you include larger particles, HEPA filters will function more effectively. They are primarily used in spotless institutions, residences, airplanes, etc.
How to determine the life cycle of air filters
Before and after an air filter, the air pressure is measured. Since airflow resistance on the output side of the filter is more significant than on the input side, air pressure is reduced. Even though the initial pressure loss is likely substantial, it may diminish as the system equalizes and the intake air pressure rises—more energy and faster HVAC system deterioration. If pressure loss is not addressed, increasing efficiency may worsen air quality and increase utility expenditures. Reduced airflow aggravates both HVAC problems and inefficiency.
