It shortens the life of your PC.  That's why so much attention is paid to cooling your system.  Fans draw air in and force it out of your PC, allowing it to flow over the chips and heat sinks in order to keep things cool.


Unfortunately, the cooling fans also suck in dust and dirt. It clings to every electronic component in your PC and prevents air from flowing across the chips. Instead, the air flows up and over the dirt, allowing heat to build up in your PC.

Inside a dirty 6-month old Pentium 4 chassisYou can prevent the build-up of dust and prolong the life of your PC with Clean-Aire Computer Enclosures.  Let the dust and dirt build up in the filter, like the ones shown below.  Then just clean and replace the reusable K&N Filter.  It's that simple.

The photo on the right shows a six-month-old Pentium 4 used in a home office.  Not much cooling going on in this PC, especially in that high end video card.  When the owner complained that his computer kept crashing, we cleaned it out and put it into a Cleane-Aire™ Computer Enclosure.  It hasn't crashed since.

You won't find much written about dust and dirt in PCs.  But, we've all known for many years what it can do to a computer.  Read the article by Larry Mingus, written in 1998.  He put the issue in perspective many years ago.

You can prevent the build-up of dust and prolong the life of your PC with Clean-Aire™ Computer Enclosures.  Let the dust and dirt build up in the filter, like the ones shown below.  Then just clean and replace the reusable K&N Filter.  It's that simple. But, don't clean your filters too soon. Even with all the dirt built up on the filters below, air flow was not restricted.     As you get to know your filters, you'll see that they are unlike any other filters on the market.  And you'll be amazed at how much dirt they stop from piling up inside your PCs and Servers.

Computer Case Airflow

Though most people rarely consider airflow within a computer case, it is one of the most critical components of any PC or Server. This is because, in order to maintain the proper operating temperature within the computer case, air must be drawn into direct contact with the chipsets on the motherboard, memory sticks, video cards, and other components.

Therefore, computer case airflow is determined by the design of the motherboard, and its placement within the case. Air is drawn into the computer case through an air intake located at the bottom of the front panel of the computer case. Exhaust fans located at the rear of the computer case and in the power supply located at the top of the rear panel, cause a negative pressure inside the computer case, and draw air across the motherboard, which is mounted vertically (tower PCs) just behind the air intake. Air is also drawn in through the small openings around hard drives, DVD and floppy drives. (Desktop computer case airflow is generally drawn in from the left front and exits from the back right.)

Some computer cases are designed with ventilation on the sides and top, in order to increase the airflow and exhaust more heat. But, increased airflow does not always mean your components are being properly cooled.

Unfortunately, most tower computers are positioned standing on the floor, where they are most vulnerable to dust and dirt, which hovers in an area about eight inches above the floor. Each time you walk by or sit down at your computer, dust and dirt are kicked up off the floor and sucked into the computer case. This is where the design of the computer case airflow works against you.

As dust and dirt are drawn into the computer case, the airflow draws that dust and dirt directly across the heated computer chips, and through heat sinks on CPUs and GPUs, which create an electro-magnetic field that attracts the dust and dirt particles. These particles stick to the chips and inside the heat sinks and disrupt the airflow within the computer case. As more dirt builds up, less and less air flows through the heat sinks or comes in contact with the surface of those chips, causing them to overheat and, sometimes, fail.

Many times, when a chip overheats, especially on the graphics card, users get the “blue screen of death” indicating a hardware failure. You can determine quickly if this is a heat issue caused by dust or a hardware failure simply by turning your PC off and then turning it on again after waiting a minute or so. If it’s a true hardware failure, the blue screen will return. If it’s a heating problem, the system will run normally – until, of course, the chip overheats again.

Some people add additional intake and/or (mostly) exhaust fans thinking they can keep their systems cooler by creating more airflow. Or, they think that, by creating positive air pressure inside the computer case, they will prevent dust and dirt from building up inside. However, this often works against them, as the fans change the airflow, which can direct air away from the components’ chips, causing them to overheat. So, if you are thinking about adding fans, make sure you take the airflow within your particular computer case into account.

Clean-Aire™ Enclosure Design

Our Clean-Aire™ Computer Enclosures are designed to provide a no-nonsense, practical approach to protecting PCs and Servers from the devastating affects of dust and dirt at a reasonable cost.

For years, we routinely downed the servers and PCs at ABC Sheet Metal in Anaheim, California to clean out the metal dust.  We also had to clean systems at other clients, like The Plant Stand in Costa Mesa, California, an exotic tropical plant distributor with PCs in their greenhouses.  But, we viewed the downtime and costs to our clients as excessive.

Though there were other dust-free computer enclosures on the market, they ranged in price from $700.00 to over $900.00 each, plus the cost of HEPA filters, adding several hundred dollars per year to the cost for each PC. So, we began working on a more practical solution.

Our first requirement was a reusable filter.  We began a testing program using baby powder.  We tested every filter we could find until we came across K&N Filters.  These high air flow filters have an overall efficiency rating above 99% and are the only reusable filters we found that could stop baby powder.

Our list of criteria included a reasonable cost, quiet operation and an attractive design.  Still, we wanted to insure that our dust-free enclosures would be able to protect computers as efficiently as anything on the market.  We believe we achieved our goals and that you will find our enclosures to be, dollar-for-dollar, the most practical and cost-effective enclosures on the market.
