Air Filter Specialists
Whether your maintenance needs are home or commercial, Global Filter Source offers the filtration expertise and extensive inventory to keep your heating and air conditioning systems operating at optimum efficiency. Installation of high-quality air filters is perhaps the single most effective strategy for improving indoor air quality and minimizing operation costs.
Filters work to keep the coils and heat exchangers on your furnace or air conditioner clean, which helps the HVAC system to work most efficiently, as well as prolonging the life of the unit.
They also help to remove particulate (dusts, allergens, mites, bacteria, mildew, mold and more) from indoor air. Different environments have different filtration requirements — homes and offices place different demands, the presence of pets and level of traffic are also factors to consider. If asthma sufferers spend time in the home or office, removing allergens from the air stream is even more important. New construction presents different challenges than older construction.
Air filters come in a wide variety of media and price points. There are fiberglass, cotton, synthetic fibers, pleated, non-woven, electrically charged metals, just to name a few. Each has its own filtration characteristics, costs and filter life. Antimicrobial filtration material inhibits the growth of bacteria, mildew, mold and fungi on the filter itself. Deciding on the appropriate air filters for your HVAC involves a balanced consideration of all of the factors of your individual circumstances.
The array of options available can be confusing. Let our experienced filter technicians help you determine the replacement filters that are best suited to your specific needs. And we'll get you set on a filter-changing schedule that will maximize your system's efficiency.
The Environmental Protection Agency (EPA) estimates that pollution inside your home or office is typically five times worse than outside air. The air in your home or office is typically streaming with tiny particles — most one micron and smaller in size (a human hair is about 45 microns in diameter). This microscopic particulate is made up of pollen, pet dander, mold spores, bacteria, viruses, dusts, smoke and more. Dirty air can have adverse health effects, particularly to the upper respiratory tract. It can also mean a dirtier, dustier home or office, with particles settling on surfaces and embedding in furniture and carpeting. HVAC systems can't operate at optimum efficiency when clogged filters prevent free airflow, and this can also negatively impact the longevity of costly heating and air conditioning systems.
Replacement Filter Overview
Ring Panel/Link Panel Air Filters - Constructed of two-to-four layers of laminated synthetic filter media, these feature an internal corrosion-resistant frame. The friction-fit gasket selvage edge minimizes inefficient air bypass. Panels may be linked to create one filter for the entire width of your air handler.
Pleated Air Conditioner and Furnace Air Filters - Generally made of a high-loft, non-woven cotton/synthetic blend media with a moisture-resistant frame, the v-shaped pleats achieve higher surface area than standard disposable fiberglass filters, for maximum airflow and enhanced particulate capture. Most should be changed every 90 days.
Electrostatic Replacement Filters - Permanent, washable filters that carry an electronic charge, which acts as an attractant to airborne particles — dust, mold, pollen, mildew, bacteria, viruses and fungi. These filters should be washed with a mild detergent and warm water when dirty.
What's in A MERV?
MERV is an industry standard rating for air filters that measures its ability to trap particles ranging in size from 3 to 10 microns. Home air filters commonly have MERV ratings from 1 to 12 — the higher the rating, the more efficient the filter is at trapping particles.
To determine a MERV, solid particles of varying sizes are introduced into the test system, upstream from the test filter. A laser particle counter alternately samples air upstream and downstream from the test filter. This is done on the clean filter and after five dust feedings. The lowest efficiency for each range is used to determine the Composite Minimum Efficiency and assign a MERV rating.
