The sensitive components within computer processors and monitors cannot withstand the hustle and bustle of a busy shop floor. Without protection, they will become coated with dust, oil, powder, and other airborne particulates. An enclosure can shield your computer from dangers presented by the environment, but there’s one problem: your equipment still needs to breathe. Filters for computer enclosures, paired with fan-driven forced air, create positive pressure and supply the enclosure with clean air that is free of contaminates. Cool air can flow freely around the computer, allowing it to breathe without encountering dangerous airborne particulates.

Filters for Computer Enclosures

How They Work

Computer enclosures cannot effectively protect equipment without consistently clean filters. They draw air in through the filter, trap airborne particulates, and then circulate the clean air around the enclosed equipment. This airs out the space and helps regulate the temperature, preventing overheating. The system forces the air out of the enclosure’s exhaust and cable ports. Since this flow of exiting clean air continues persistently, creating a positive pressure airflow system, contaminated air cannot enter the enclosure. Your enclosure’s filters must be clean and routinely changed to perform this task successfully.


Filters play an important role no matter where your enclosure is located. Even in relatively mild environments, airborne particulates like plain-old dust and moisture can harm your equipment, causing corrosion, overheating, repairs, breakdowns, and general wear-and-tear. To get an idea of the ways in which environments impact enclosures and their filters, check out the following list of harmful environments and their potential airborne particulates:

  • Machine shops (metallic dust, metal shavings, smoke particulate, oil mist)
  • Concrete industry (sand and gravel particulate, cement dust, fly ash)
  • Paper and cardboard industry (paper dust, wood chips)
  • Bakeries (flour, sugar, yeast, baking powder, and other finely ground ingredients)
  • Agriculture (dust from hay, animal bedding, livestock, grain, fuel chips)
  • Wood manufacturing (sawdust, wood chips, dirt, smoke)
  • Textile industry (textile fibers, dust)

A dirty filter is an ineffective, inefficient filter. Routinely replacing your enclosure’s filter is the key to ensuring that your enclosure works properly and protects your computer equipment. Your replacement schedule will depend on your environment: the types of airborne particulates, the amount, the equipment you’re using, etc. The chart below lists recommended replacement schedules for some common industries. Typically, replacement is necessary every one to two months.


Performing this preventive maintenance and addressing any other issues that arise ASAP will help you avoid major problems that could disrupt your business’s productivity and revenue. Preventive maintenance can also extend the lifespan of your equipment and ensure that it continues to operate efficiently.

How to Purchase Filters for Computer Enclosures

If you’re looking to purchase filters for computer enclosures, contact DustShield today. Our filtration systems are effective in removing up to 98 percent of all airborne contaminants, and they’re five times more effective than washable, permanent electrostatic filters. We offer two types of filters: a Heavy-Duty Particulate Filter (DS512) and a Particulate & Fumes Filter (DS612). Both filters utilize activated carbon, a form of processed carbon that has been treated with oxygen to create many tiny pores between the carbon atoms. These pores increase the product’s surface area, so that it can better absorb contaminants and impurities.

Heavy-Duty Particulate Filter

An all-purpose filter, our Heavy-Duty Particulate Filter uses activated carbon and electrostatic filtration media to remove all airborne particulates. It suits most production environments and removes particles as small as 0.1 micron in length. Each package contains 12 filters.

Particulate & Fumes Filter

The Particulate & Fumes filter is a specialized filter for production environments that include heavy truck and forklift traffic, cutting lubricants, and sulfur (metallurgy). It includes double the amount of activated carbon filtration to remove particulates from especially dirty air containing oil, exhaust vapor, and fumes. Each package contains 12 filters.


DustShield Particulate & Fumes Filter (DS612)

In addition to filters, we offer an extensive line of computer enclosures that are industrial tough, factory-floor ready, and designed to protect LCD monitors, tower and desktop CPUs, and printers. So if you would like to protect your equipment, check out DustShield’s computer enclosures today. To learn more, please give one of our enclosure specialists a call toll-free at 800-587-9557 or contact us online.
