7 Best PC Dust Filter Reviews and Buying Guide 2021

by S.I. Quick

So, we have had our workstations for a while now. Recently, we noticed that whenever we want to make them handle something resource-intensive, the fans go into full speed and make way too much noise. The temperature climbs up reasonably quickly too.

To investigate the matter, we popped open the cases. And guess what? It was a dust city inside. Fans were clogged, the CPU cooler had a thick layer of dust, and the GPU looked obnoxious. That is where we wanted to pick the best pc dust filter.

However, even though the available options claim they can block 100 percent dust, most of them lower airflow substantially. But eventually, after testing about 20 of the filters, we did manage to find seven worthy ones, which we will talk about in this article.

Benefits of Using PC Dust Filter

First, we would like to ensure that you clearly know what benefits you would be getting after installing one of these pc air filters.

Keeps Dust Away

Just like the name suggests, these will filter out the dust from the air. All these dust particles eventually get sucked up by the fans, finding their way on the components.

Optimal Temperature

After the dust particles settle on the fan, they can restrict the movement of the bearing substantially. That will mean a lower amount of airflow. And an inadequate amount of airflow will make the components get hot reasonably fast, eventually resulting in performance throttling.

Less Effort on Maintenance

It is recommended to clean up the computers after every six months or less. Without dust filters, there will be too much dust inside the cases and components. That would mean that you would need to put a good amount of effort into cleaning the internals.

But that will not be the case if an air filter is installed. There will be considerably less dust, and you will not have to spend hours cleaning the components and the fans.

Our Top 7 Best PC Dust Filter Reviews

Trust us; there are a lot of dust filters out there that will claim to keep the performance up while keeping the dust level low inside the case. But not many can deliver that. Through our intensive tests, we found these to deliver that and beyond:

In the package, you will receive two dust filters. Each of them is 360 mm x 120 mm in size. Such a size makes these perfect for workstations with large radiators and cooling fans attached to the casing. They can also cover the total surface area adequately. There will basically be no spots for the dust to pass through.

These have a hole diameter of 0.5 mm. Due to the hole being small, these can offer an exceptionally high level of dust protection.

Although the 120 mm fans are pretty common, some of the workstations require more airflow. That is why many PC builders rely on 140 mm fans. And these meshes from AIYUE are precisely for those builds.

The design of these meshes is not like something that you would find on a regular dust filter for computer. Instead, the manufacturer has opted for ultra-fine holes. These holes can effectively block out the dust particles from the air. For that reason, the fans will have a lower chance of getting clogged over time.

As the ultra-fine hole does not block or lower the intensity of air intake, the components inside will get adequately cooled. That means you will not have to worry about the PC overheating when you are carrying out a resource-intensive task on it.

These meshes have a perfect size as well. They can cover an entire two-fan radiator or two individual fans. Even though these are pretty large in size, they will not leave any unnecessary gaps for the dust to enter the chassis. The build quality is praiseworthy as well.

Things to Consider Before Buying PC Dust Filter

Before you decide to spend your precious money on one of these filters, there are a couple of things that need to be in your mind. And they are:


First and foremost, consider the size. Most of the workstations require a higher amount of airflow, which is where the 140 mm fans come into play. However, the standard size for PC case cooling fans is 120 mm.

Now, if you are confused regarding the size of the fans, just check the label on the fans. It should state 120 mm x 120 mm or 140 mm x 140 mm. Choose a dust filter by keeping that dimension in your mind. If you happen to get something large, the case might not fit the screen properly.

And if you get something smaller than the fans, there will be gaps through which the dust particles will get inside. Also, consider whether you want to cover individual fans or multiple at once. Opt for the 120 mm x 240 mm or 140 mm x 280 mm to cover two cooling fans at once.

Installation Process

The dust filters will usually have two types of installation processes. One will rely on screws, while the others will use a magnetic frame. The units that utilize screws are not as convenient as the magnetic frame. You would need to install them using a screwdriver, which can take a reasonable time if you have multiple fans.

On the other hand, the ones that have a magnetic frame will be easier to install. All you need to do is place them on the mounting region, and they will snap into place. Taking them off will be easy as too.


Another thing that you would need to consider is the design. We would recommend getting the ones with ultra-fine holes. Those will be capable of blocking out the dust from the incoming air exceptionally well. And even though these will filter out dust reasonably well, they will not restrict the airflow.

As the airflow will remain optimal, the components will run at an optimal temperature, and there will be no chances of performance getting throttled because of extreme heat.


Last but not least, consider the overall durability of the mesh. Usually, most of these will be of PVC or aluminum. The higher the quality of the material, the more durable the mesh will be. And the filters with higher durability will last for a considerably long period of time.

Why We Should Use PC Dust Filter

Are you still wondering why you should consider purchasing one of these? Let us tell you what can happen if you do not pair your PC case with dust filters.

Fans Getting Clogged

When there are no dust filters, the fans will have too much dust build up over time. And that would lead them to be clogged. As a result, they might make too much noise during operation.

Temperature Rise

If the fans struggle to offer the right amount of airflow to the inside, the temperature of the components will rise when you operate the PC. You might even notice significant performance throttles.

Time-Consuming Maintenance

Without dust filters, there will be too much dust built up inside the casing. You will find a thick layer of dust particles on the components. As a result, you would need to put a reasonable amount of time into cleaning the chassis.

PC Dust Filter Frequently Asked Questions

1. What size of dust filter should I get?

That will depend on the dimensions of the cooling fan you have installed. If it is 120 mm x 120 mm, you need to get the filters for that specific fan.

2. Are dust filters for PC washable?

It depends. Some will be washable, while others will not. Refer to the instructions of the manufacture before washing these.

3. Will the mesh of the dust filters get loose over time?

Most of the filters will use 3M adhesive, which offers a reasonably strong bond. So, you will not have to worry about the mesh getting loose over time.

4. How many meshes do I need for my PC?

If you have a total of four cooling fans on your chassis, you would need four of them. You can also opt for the double-sized ones if your case allows you to install them.

5. Is it hard to install PC dust filters?

Not at all. Even the ones that have screws will be relatively easy to install. But if you want the most convenience, opt for the ones with magnetic frames.

Final Words on PC Dust Filter

Without installing the best pc dust filter, it would be impossible to control the dust inside the PC. You would also face overheating issues, and the maintenance task will be more complex than it has to be. And we ensure that each of the models we have covered will eliminate all of the issues we have discussed here.

However, if you want us to choose one, PANO-MOUNTS 360mm 120mm x 2 would be the one. It is highly durable and highly capable of filtering out dust.
