The Ultimate Guide to Choosing Fiberglass Filter Manufacturers

Let&#;s face it, air filtration in an industrial setting can be daunting. Knowing which filters are required for a variety of applications in the same building can mean cumbersome research and expensive trial and error. Knowing that fiberglass filter media rolls are needed for paint, HEPA filters for ventilation, and carbon filters are for gases is just the beginning. Sizes, quantities and frequency of change outs becomes your next problem. Luckily Robinson&#;s Filter Solutions is here to help with this comprehensive guide to common industrial air filters.

What is an air filter? What makes one any better than another? Let&#;s venture out to explore those answers.

What Is an Air Filter?

An air filter is a device that allows air to pass through but stops certain air contaminants from travelling with it. These contaminants could be as large as human hair or measured in microns. The type of filter determines the various pollutants and sizes a filter can remove. Many types of filters exist, such as&#;

Fiberglass Filter Media Rolls

Fiberglass filter media rolls are composed of media fibers bound together tightly, creating an ever-increasing density to trap dust particles. They&#;re commonly used in the auto-painting industry, where landing dust could destroy a perfect finish. But they work anywhere you need a smooth painted finish, from gym equipment to consumer electronics.

This type of filter is so versatile that it can be cut into virtually any size and shape to work in various industrial settings. Fiberglass filter media rolls can remove 98% of particles from the air, so they&#;ll be more than sufficient for most industrial settings.

HEPA Filters

We all hear about this one a lot, but do you know what a HEPA filter is? It filters using polypropylene (plastic) or fiberglass pleats that remove 99.97% of particles from the air. Those particles can be as small as .3 microns (That&#;s tiny!) For reference, human hair has a diameter of around 80 microns.

Carbon Filters

Carbon (a.k.a. charcoal) can be combined with other filtering materials to attract certain gas particles that might otherwise slip through the filter. For example, it can reduce industrial fumes, cleaners, or gaseous manufacturing byproducts to the point that they&#;re not detectable&#;if present at all. When activated, the charcoal is highly porous, allowing it to trap some of the smallest particles in existence.

UV Filters

Other filtration materials can also be combined with UV to eradicate harmful pathogens. These filters often find themselves in hospitals and surgery centres where the risk of infection is high and dangerous to patients and staff.

Plastic filters

Plastics have the benefits of being washable, unlike other filters that you must replace when their service life has come to an end. Despite being plastic, this can be an eco-friendly option if you wash the filters rather than replace them. They can last for years.

How to Evaluate Air Filters?

You can&#;t learn everything about filters without understanding the MERV scale, or Minimum Efficiency Reporting Value. Filters undergo extensive testing and receive MERV ratings of 1 to 20. Everything from Fiberglass filter media rolls to a new brand of HEPA filter must complete the tests.

The higher the number, the more particles a filter removes. HEPA filters typically score around 17 or higher. But, it&#;s important to note, that the MERV score only measures solid particles, so, hypothetically, a carbon filter could be designed to remove foul odours and do it very well but get a lower rating because it doesn&#;t remove small solid particles. At the end of the day, it is important to have a cursory knowledge of the filters used in your particular industry, however, why not rely on the experts when it comes to having the best filter for the job?

Running your furnace, central air, or heat pump probably constitutes a big part of your utility bill. But it&#;s a small, often inexpensive part&#;the air filter&#;that keeps these heating and cooling systems humming along. And it also plays a role in maintaining good air quality inside your home.

For these reasons&#;and because every forced-air heating and cooling system uses at least one filter&#;it&#;s important to know how and when to replace it. 

Some background: Forced-air heating, ventilating, and cooling (HVAC) systems work on a loop. They &#;inhale&#; through return vents in your living space, pulling air through ductwork and across your heating or cooling source (either a furnace&#;s burners, or an AC or heat pump&#;s coil). Then they &#;exhale&#; through supply ducts and vents, delivering warm or cool air to your living space. Inevitably, some of the hair, dust, and other debris in your home gets sucked into that loop as air circulates around your house.

It&#;s an HVAC air filter&#;s job to catch that debris. In doing so, it first and foremost protects your heating and cooling equipment from damage. As a bonus, it can improve your indoor air quality. In fact, manufacturers claim many of today&#;s filters can capture allergens, microbes, and other particles while they&#;re doing their primary job of keeping your system gunk-free. And with the prevalence of wildfire smoke, air filters are even more important. (Here are the best filters for dealing with smoke-filled air, according to CR&#;s ratings.)

There are a range of HVAC filter designs: The basic models are made from strands of fiberglass (for disposable filters) or metal mesh (for reusable filters), and can stop big debris. Higher-end filters are made from material more like a surgical mask&#;s, arranged into pleats, and at their best, they can capture particles as tiny as bacteria, and sometimes even viruses before they can recirculate. 

You should expect to replace your filter every three to 12 months of use, depending on the size of the filter. For 1-inch-thick filters, three months is the usual recommendation. For 4-inch and thicker filters, 12 months is common.

You might need to replace the filter more frequently if you have a few very furry pets, for example, or you live in an area with a lot of air pollution, such as from wildfires. When HVAC filters get dirty and clogged with debris, air can&#;t flow freely through your ducts, which makes your home less comfortable and can eventually break your HVAC equipment. 

The good news is that fresh HVAC filters can be budget-friendly and are usually simple to replace. 

In this guide, we&#;ll help you figure out which filter size your HVAC system needs, how to pick the right amount of filtration, and how to swap in a filter on your own&#;usually with no tools required.

CR members can also see our comprehensive air filter ratings for HVAC filters, based on extensive lab testing. We have ratings for almost 70 models across a range of thicknesses, prices, and performance ratings. Many filters that we review are available in multiple width and height configurations, so our recommendations should cover almost any kind of forced-air system.
