What are the disadvantages of using a fiberglass air filter?
Fiberglass filters are only designed to remove the largest particles from your home’s air. That means that they provide a minimum amount of protection for your heating and cooling system, and they do very little to protect your health (see below). Not effective for asthma or allergies.
What is the difference between a fiberglass and a pleated filter?
Pleated filters are made from a sustainable fabric, which is biodegradable and good for the environment! The surface area of pleated filters is greater, so it traps more particulates in the air than other filter designs (making the air you breathe cleaner). The unit cost of pleated filters can be a little bit higher than fiberglass.
Why choose fiberglass HVAC filters?
Because fiberglass allows greater airflow, it also allows a greater number of particulates to pass back into your home. No matter which filters you go with, it needs to be able to trap particles like dust, smoke, and pet dander.
What are fiberglass air filters?
Fiberglass filters are the 1-inch blue filters that can be found at most hardware and large retail stores. They are made of spun glass that captures large particles from your home’s air and typically come with a MERV rating between 1 and 4.

The biggest advantage of using fiberglass air filters is that they are inexpensive when compared to more advanced filters like pleated filters or whole-house air cleaners. You can typically buy an individual fiberglass filter for under $3, and you can find them at almost any department, grocery, or large retail store.
What are the disadvantages of fiberglass air filters?
Must be changed every 30 days., 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.
What is the best air filter for HVAC?
At a minimum, for your health and the health of your HVAC system, it’s best to always use an air filter rated MERV 8 or higher. When you compare a MERV 4 vs MERV 8 filter side by side you will find a tremendous difference in particle trapping. This does mean that an air filter with a MERV rating of 8 or higher can get dirtier quicker but it also means spending less money on cleaning your furnace, less time dusting your furniture and less doctor visits if someone in your household is affected by allergies.

While a hospital or surgery room may need MERV 20 rated air filters to maintain a healthy environment, usually MERV 13 is the highest grade air filter recommended for residential home furnaces and HVAC systems.
What air filters are best for removing hairspray?
People can literally breathe easier in homes that use air filters with higher ratings because MERV 8 rated filters can remove smaller particles like hairspray, MERV 11 can remove auto emissions and lead dust, and MERV 13 can remove all types of bacteria and most tobacco smoke.
Why is it important to change your air filter?
That’s why it’s important to regularly change your air filters in order to keep your system working at peak efficiency. Using high-quality air filters, a programmable thermostat and making sure air flow isn’t being blocked by furniture or drapes are important steps to take toward reducing your energy bills.
Do furnace filters have fiberglass?
We can’t speak for all high MERV air filters but our furnace filters do not have any fiberglass in them. Our filters are hand made in the USA and are made of the highest quality. The filter material is made up of a mixture of cotton and polyester fibers surrounded by a heavy duty- moisture, mold and mildew resistant cardboard frame.
What Are HEPA Filters Made Of?

With That ‘being said, pleating’ makes the HEPA filter much more effective.
What is the difference between fiberglass and pleated air filters?
Fiberglass tends to allow greater airflow, which puts less strain on weaker HVAC units. Per unit, fiberglass filters tend to be cheaper than pleated filters . Fiberglass filters are often see-through. If you hold them up, you can test this.
Why are pleated filters better than other filters?
The surface area of pleated filters is greater, so it traps more particulates in the air than other filter designs (making the air you breathe cleaner).
Is fiberglass filter cheaper?
When it comes to cost, fiberglass filters per unit do tend to be cheaper.
Do fiberglass filters need to be replaced?
Fiberglass filters need to be replaced more often than other types, which brings up the total cost (as well, the added inconvenience).
Do filters make a difference?

It’s still an air filter. But, on the other hand, if you’re looking for superior air quality, long-term savings, and the convenience of changing your filter less often, then let Filter King help you get the right air filter.
Do pleated filters beat fiberglass filters?
Due to their efficiency, sustainability, and cost-effectiveness, pleated filters beat fiberglass filters in almost every category. However, if you happen to be shopping at a store that only sells fiberglass filters, and if you’re desperate and need one right away, then go with the fiberglass filter. It’s still an air filter.

Because of this, fiberglass filters can be more expensive in the long run because you are buying more filters. The materials used to make fiberglass filters cannot be recycled and are not biodegradable .
How much does a pleated air filter cost?
They are more expensive than fiberglass filters initially - ranging from $5-$20 - but are the superior choice for home air filters for the following reasons:
Which is better: a pleated or fiberglass filter?
Pleated air filters provide better overall air quality, with MERV ratings ranging from 7-13. Their increased surface area picks up more debris and pollutants than fiberglass filters, such as pollen and pet dander in addition to picking up dirt and dust and larger allergen debris.
Can a pleated air filter be recycled?
Pleated air filters can be recycled upon their disposal, thereby making them an eco-friendlier choice than fiberglass filters.
Is fiberglass air filter cheaper than pleated air filter?

Why is Fiberglass Used in HEPA filters?
This is because the glass wool composite material is successful in being an effective filter that sieves out the smaller particles. In addition to that, fiberglass is a widely available and affordable material to be used in such air purifiers.
What is Fiberglass?
Fiberglass, sometimes referred to as glass wool is an artificially made plastic composite. The composite is pleated and woven with glass fibers using extreme heat and special adhesives. Glass fiber is strikingly similar in looks and manufacturing process to any other glass that you observe around you.
How does a hepa filter work?
2 of these outer filters work as a sieve that discards the bigger impurities. The inner fiberglass filter is densely pleated to create greater surface area and stop particles that are as small as 0.3 micrometers.
How long does it take for a HEPA filter to work?
On average, turning on the HEPA filter for 6 to 8 hours can produce up to 800 fibers from the filter. While that sounds like the filtered air is full of glass particles, experts say that it is well below the breathable particulate matter or PM2.5 level. This level is considered safe, as we are obliviously breathing as many particles even on the cleanest of environments.
What size filter do they use to test shedding?
To test the shedding, they used a filter with a 0.4 mm gap size.
What is UV filter?
These purifiers are popularly called UVGI air purifiers and use filter-less technology to get rid of impurities from the air. UV systems use ultraviolet light that has a shorter wavelength to destroy any pathogen or contaminants present in the air.
How is fiberglass made?
Similar to window glass, or tabletop glass, fiberglass is also composed by melting the glass using enough heat, followed by sizing them to the thinnest micron sized particles. The material can be structured quite easily and is therefore used in a wide range of home and industrial applications. From aircraft to insulation pipes and household appliances, they are just about everywhere.
How many microns are filter fibers?
Laboratory examination of a filter sample sent by the client to an independent microscopy laboratory found that the filter fibers were 31 microns in diameter, and had a blue coating on them [probably the binder, and not the fragments shown in our photos here.].
