Disposable fiberglass: These filters typically have MERV ratings of
1-4
. They have the capability to prevent large particles from getting into your system. While disposable fiberglass filters are inexpensive, costing a couple of dollars at most, they won’t do much to improve indoor air quality.
Are MERV 13 filters made with fiberglass?
For example, the filter media in our MERV 13 pleated filters is made of
polypropylene/acrylic fibers
. This high-quality, synthetic, plastic-based material allows the filters to trap particles as small as lint, dust mites, mold spores, pollen, pet dander, fine dust, smoke, viruses, and bacteria.
How efficient is a fiberglass filter?
For reference, a pleated filter of only a MERV 8 rating filters out at least 75% of particles between 3 and 10 microns. … Fiberglass filters are so efficient with particles this small that
their percentage is pretty close to zero
.
What is a fiberglass filter?
Fiberglass filters – These are
glass mat filters composed of 15–60 μm glass fibers with a high porosity
. These are the most common filters used in residential furnace and air conditioning systems. They are low cost. … The fibers most frequently used are cotton and polyester.
What MERV rating air filter should I use?
Using an air filter with a MERV rating of
about 5 to 8
is appropriate for most residential homes. MERV 5 – MERV 8 filters provide good filtration and will remove most pollen, mold spores, and dust mites. … Generally, pleated filters have a higher MERV rating, while non-pleated filters have a lower one.
Can my furnace handle a MERV 13 filter?
The ideal MERV filters for both air filtering and furnace efficiency are
7-13
, experts say. These filters can be used without any modifications to your equipment. Your system may handle MERV 14-16 with no discernable stress. However, many residential systems require modifications to pull air through these filters.
Is MERV 12 too restrictive?
| MERV Minimum Particle Size | 9–12 3.0–1.0 μm | 13–16 1.0–0.3 μm | 17–20 < 0.3 μm |
|---|
Are fiberglass furnace filters bad for lungs?
With a MERV rating of 1-4, fiberglass air filters can usually remove the largest of particles from the air like maybe some pet hair, dust bunnies, and cheerios but
they are terrible at stopping the harmful particles
from infiltrating your furnace and lungs. … The layers become more dense thus filtering more effectively.
Can you vacuum a fiberglass air filter?
Vacuuming a Filter
Can’t Reach
the Inner Fibers
The contaminant particles can get buried deep in the filter’s fibers, so a vacuum cleaner won’t extract all of them. The particles will create a barrier in the air filter and prevent air from passing through, which could damage your HVAC system or make it less efficient.
How long do fiberglass filters last?
Unlike many advanced filters that can last 3 months or more, fiberglass filters are only designed to last for
30 days at a time
. After 30 days, they lose effectiveness and need to be replaced.
Is there fiberglass in Filtrete filters?
Materials matter
In fact, FiltreteTM Filter media is
less than 15 percent fiber
; the rest is air. This very low density allows air to easily flow through the media. It also increases its ability to capture particles through the depth of the pleated media, not just on the surface.
Does it matter what kind of air filter I use?
The short answer is,
no
, they’re not all the same. In fact, there are many different types of air filters available and choosing the right one can make a real difference in the lifespan of your HVAC system. … All filters are rated using the MERV scale.

Is MERV 11 too restrictive?
A MERV 11 air filter has a higher efficiency rating. Meaning, it can capture finer particles and clear more contaminants out of the air. … In most cases, a MERV 11 air filter
isn’t too high for residential use
.
What MERV rating do I need for Covid 19?
What kind of filter should I use in my home HVAC system to help protect my family from COVID-19? Minimum Efficiency Reporting Values, or MERV, reports a filter’s ability to capture particles. Filters with
MERV-13 or higher ratings
can trap smaller particles, including viruses.
Is MERV 8 good enough?
MERV 5–8
(good):
These filters are better at catching small particles (3–10 microns) like mold spores, hair spray, dust mites and animal dander. MERV 9–12 (better): The best option for residential use.
