About Grades of Glass Micro Fiber Depth Filters

In depth filters such as glass micro fiber, the purity of the filter is dictated by the presence of, if any, binder material that acts as a strengthening agent and aids in holding the fibers together.

Because of the characteristically high flow rates of depth filters, they are generally used in applications such as single and multi process removal of sediment and course particulate. Glass micro fiber filters are available without binders, making the inert matrix an ideal medium to entrap sediment for further analysis and counting. Also, depth filtration media is commonly used as pre-filtration prior to surface filtration substrates such as membranes.

Grade C has several sub groups as follows

CFP1: Very widely used filter media demonstrating a retention of approximately 11m and medium flow rate. Used in a broad range of laboratory and environmental applications, this media is ideally suited in separating lead sulfate, calcium carbonate and calcium oxalate precipitates. This media is the standard for agricultural procedures such as soil and seed sample testing. Also, it is commonly used as a separation media in the food and beverage industry to extract liquids from solid samples.

Due to the consistent bright white color of this media, it is ideal for photometric stain intensity measurement of air samples. The media can also be impregnated with reagents for use in quantifying optical reflectance in gas detection procedures.

CFP2: More retentive and absorbent media that CFP1, with approximately 8m and a medium to slow flow rate. This media is ideal for general filtration and absorbent conveyance. Commonly used in plant growth trials and monitoring pre-isolated contaminants in air and gas.

CFP3: Virtually identical to CFP1, but twice as thick resulting in a significantly slower flow rate with a retention of approximately 6m. This media does not clog as easily as the other qualitative cellulose types, which allows for much higher sample volume usage. This media also demonstrates very high levels of absorbency, permitting the media to be used as a sample conveyance substrate.

CFP4: The fastest flow rate demonstrated by any of the qualitative cellulose filter media resulting in a low retention rate of approximately 20-26m. Very commonly used as the first media in a multi-stage filtration process. Ideally suited for use in organic extractions and biological fluid separation processes. Often specified in air monitoring applications where the entrapment of fine particulate is not required.

Grade D - Coarse porosity, fast flow rate, with a 2.7m size particle retention. Well suited for higher volume and repetitive laboratory filtering. Also ideally used as a general pre-filter to extend primary filter life. Binderless borosilicate glass microfiber.

Grade E - Fine porosity, fast flow rate, with a 1.3m size particle retention. This material is an economical media for suspended particle analysis in water, cell harvesting, pre-filtration and air monitoring applications. Binderless borosilicate glass microfiber.

Grade F - Fine porosity, medium flow rate, with a 0.7m size particle retention. Frequently used with Grade D to filter diluted aqueous solutions containing strong oxidizing, acidic, or alkaline components prior to laser spectroscopy. May also be used for TCLP analysis and collecting extremely fine precipitated proteins, including immunoglobulins.Binderless borosilicate glass microfiber.

Grade A-E - Fine porosity and fast flow rate, with a 1.0m size particle retention. Binderless borosilicate glass microfiber.

DOP efficiency is 99.98%. Primarily used in suspended solids and air monitoring.
Quartz A - Fine porosity with a 99.999% efficiency in air filtration for the retention of 0.6m particles in air at a flow rate of 5cm/second. Primarily used in air pollution monitoring, atomic absorption spectroscopy, flame emission spectrometry and other applications where an extremely critical analysis is needed. Effective temperature range of up to C. Binderless quartz micro fiber.

Homeowners don&#;t always know where to start when it&#;s time to choose an air filter. Because there are several types available at most stores, it&#;s easy to base your buying decision just on price alone. However, while the cheaper fiberglass air filter might seem like a smart idea for your budget, it may not always be the best choice for your home, your HVAC system, or your family&#;s health.

Will it trap all the particles you need to be filtered in your home or business to improve the

To determine which is the best air filter for your home furnace or air conditioning unit, you'll need to consider a few key factors:

Not recyclable: Fiberglass is not a recyclable material, and because you must replace fiberglass filters more often, you'll be sending more trash to the landfill.

Less filtering capability: Because they don't have a lot of surface area, they don't filter out smaller items like pollen, bacteria, and viruses. This makes them a poor choice for people who suffer from allergies, asthma, and other sensitivities.

Quality: An especially flimsy fiberglass filter can come apart in your system, causing serious damage, as well as putting any filtered debris back into the air.

Airflow: New fiberglass filters will not impede airflow. However, if you don't change your fiberglass air filter monthly, it may become clogged and impede airflow, which will create issues for your unit.

Frequency: Pleated filters can last up to 90 days before they need to be replaced, depending on the time of year and the environment in your home or business.

Catch more debris: Pleated air filters have more surface area, so they capture more &#; and smaller &#; debris. Depending on the MERV rating, they may filter out pollen, pet dander, bacteria, and some viruses. This makes a pleated air filter a much better choice for anyone with allergies, asthma, or similar sensitivities.

Frequently Asked Questions about Fiberglass and Pleated Air Filters

Are fiberglass air filters safe?

Yes, for the most part, fiberglass filters are safe. But they fall short compared to pleated filters when it comes to filtering out the smaller contaminants in your air such as pollen, pet dander, and bacteria. You should also be aware that, because they don't have a lot of surface area and don't filter smaller particles out, they eventually can cause build-up and weaken your HVAC system and decrease its efficiency, which may lead to higher energy costs.

What is a pleated filter?

A pleated filter is an air filter that is made from a pliable material &#; polyester, cotton, or paper &#; that is folded to look like an accordion and housed in a cardboard frame. The folds &#; or pleats &#; give the filter more surface area, which allows it to capture more particles.

What are pleated air filters made of?

Pleated filters can be made of paper, cotton, polyester, or other pliable materials. 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.

Are pleated air filters better?

While fiberglass air filters will do the job in the most basic way, in most cases, pleated air filters are much better. They can filter out smaller particles &#; important for people with airborne sensitivities. They are less likely to clog in a short amount of time, and they can last up to 90 days. They're also recyclable in most communities, which makes them a good choice for the environmentally conscious.

My property manager says fiberglass is the only material my unit can handle. Why would that be true?

While we don't know the exact reason that your property manager would make that claim, our guess is that he's concerned about airflow through the building's ventilation system. Fiberglass filters, when changed regularly, do allow for more airflow because they have less surface area than pleated filters and allow the smaller particles to get through. However, if you don't change them every 30 days, you'll find they have the opposite effect by getting clogged and potentially harming your system.
