Like other projector parts, the filters are an important component that helps the projector to keep running smoothly and efficiently.
Over time, when these filters remain uncleaned and dirty, the dust inside the projector starts getting collected and slowly stops the fan from working.
If the air filter is left uncleaned for longer, it can affect the projector’s performance or even permanently damage its parts.
When the filter is clogged, it can reduce the airflow and cause it to overheat, shortening the projector’s life.
So, it is important to regularly clean the filters to enhance the model’s life to help the fan work properly.
- A soft brush.
- Clean cloth.
- A screwdriver or other tool to remove the clips or screws.
How to clean a projector filter?
Generally, the new projector models automatically give a notification on the screen, or a yellow light glows, which indicates the projector filter needs to be cleaned.
But the older model does not have the sensors to detect, so you need to clean the filter every 100 hours of usage.
If your room has lots of dust or the windows are open most of the time, then cleaning the projector filter in three months is recommended.
Here is the step-by-step guide on cleaning the projector filter with an easy process.
Cooling the projector
The first step is to turn off the projector and unplug it from the power outlet and other connected sources, like an external speaker, screen, connection cable, etc.
Wait for at least half an hour which will allow the projector to cool down, before cleaning the filter.
Finding the filter
Almost all the projector air filters are located on the panel’s side. But there are a few models whose filters are located behind a removable panel or cover.
If you still don’t find it, you need to read the user manual guide, which will give the exact location.
Also, multiple models come with two filters, one at the side and the other at the back.
After finding the filter, it’s time to open it with a screwdriver. Now take the filter out and keep it on a table.
- Take a soft brush and give soft cleaning.
- Clean every corner of the air filter.
- Never wash the filter with water. If you feel the air filter is too dirty, it is best to replace it with a new one.
- After cleaning, it is time to put the filter back in its original location.
Now switch on the projector, and you will notice a clear image on the screen. Also, the fan will work more efficiently, making less noise.
Why cleaning the air filter is not recommended using water?
Cleaning the filter using water or mild detergent soap can damage the layer, which protects it from dust entering the projector.
On the other hand, if detergent is used, it will require more water pressure to remove from every corner, which might damage the protective mesh.
But you can clean the cabinet with water which holds the air filter as they are made of plastic.
Can I use Canned Air To Clean Filter?
If the filter has lots of dust and is not going with the help of a brush, then you can use canned air to remove all that particles.
But using an air canned filter, first, you need to check on the plane surface and how much pressure it gives.
If the pressure is too high, it might harm by making holes inside the filter.
So, using canned air ensure that you should maintain a safe distance to avoid any damage done to it.
What should I do if the dust is not going?
If you have applied all the above methods and still the dust is not going, then it’s time to replace the filter with the new one.
How often should you clean the projector filter?
Cleaning the projector filter depends on how often you use it and the environmental condition where the unit is placed.
If you use the projector too often, then after 100 hours, it is safe to clean it with the above steps.
If you use a portable projector for business meetings in different places, then cleaning should be done within three months.
Is it necessary to clean the projector vents?
Cleaning projector vents is as important as cleaning the air filter. If you leave the vents uncleaned, the dust collected on it will start getting inside after a few days.
How to check the temperature of my projector?
If you have the latest projector model, the yellow light pops up on the panel when a sudden temperature rises, letting you know it is time to clean the air filter.
Also, the fan’s noise will increase even if you use the unit in low brightness mode.
The above method will take at least fifteen minutes to clean the air filter from dust properly.
But it might take half an hour to do the cleaning if you are doing it for the first time. So, patience will play a key role while doing the cleaning process.
