What Freehold NJ Furnace Heating Companies Should Share About Air Filtration

While you already know that not all air filters are created equal, winter and summer expose the flaws of poor air quality due to the wrong filter. Not all Freehold NJ heating companies take filtration beyond meeting the manufacturer’s minimum filter needs.

That’s often because of the difficulties in getting NJ homeowners to stick to any consistent replacement regimen. But if family members have allergies, are smokers, or are prone to other common air quality pollutants, the quality of air filtration that you choose is a much bigger deal.

Air filters vary broadly by material, cost, size and function. MERV, which stands for Minimum Efficiency Reporting Values is the 20-point scale that rates filter effectiveness in stopping pollutants. Lower numbers mean lower quality, and the higher numbers indicate the filters that eliminate smaller, micro-level particles. Different types of filters include:

Mechanical filters made of disposable fiberglass surrounded by a cardboard frame are the most common and least expensive. they block about 75 percent of large particulates, almost none of the smaller particles, and have a MERV rating of 2.

Pleated filters are made of a disposable polyester-cotton blend paper that removes nearly 100 percent of large particles and 50 percent of smaller particulates. They
generally cost twice as much as mechanical filters, and while they can theoretically be replaced less often, that depends on individual household factors. The tighter weave of the filter does a good job of filtering out particles but becomes full and clogged faster.

Disposable electrostatic filters have an electrostatic charge to attract pollutants but have a short shelf life despite a MERV rating of 10 and a higher cost.

Permanent electrostatic filters are similar to the disposable type but sometimes include a plastic blade component. Like the disposable filter, it has a 75 to 95 percent effectiveness rate on large particles and up to 15% with small ones.

Electronic filters use a high-voltage charge from a power source to attract particles and are often recommended for allergy sufferers. With more than 95% effectiveness for large particles and from 75 to 95 percent on the smaller matter, they have a MERV rating of 8-10.

HEPA filters are considered optimal and are made of dense, thick cotton or polyester blends that catch virtually every particle including dust, mold, spores, bacteria, hair and dust with a greater than 95% effectiveness rate of removing small and large particles.

System installation can be expensive, but filters and pre-filters get changed every one- to-three. A HEPA filter costs around $100 and has a MERV rating of 16-20. The reality is that the Environmental Protection Agency states: “Filters with a MERV between 7 and 13 are likely to be nearly as effective as true HEPA filters.” This is often more information than most Freehold NJ heating companies will provide to homeowners. But as stated earlier, many homeowners don’t trace stuffiness and sneezing to the quality of their furnace filter, so they don’t ask or do the research on
their own.
