In the air conditioning system, the air conditioning filter is an important and essential air conditioning part. It is important due to its work of filtering any pollutant to make the conditioned air breathable and clean. However, cleaning these air conditioning filters is also very essential in order to get the best efficiency from a central air conditioning.
Most air conditioning filters are able to remove dirt particles of sizes from 3 to 10 microns such as animal dander, pollen, dust, mold, radioactive particles, and other most toxic particles.

Why cleaning of air conditioning filters is important
- All air conditioning parts are closely inter-related with each other. If the filters are dirty, it will reduce the service life of the air conditioner and increases its maintenance cost.
- Dirty filters also cause higher energy costs.

What to do for maintenance of air conditioning filters?
Changing of filters should be done periodically. For homes, a period of one month during the heating or cooling seasons is adequate, but commercially used air conditioning filters may need replacement as often as every couple of weeks.
Many of us don’t change them until we see dust and dirt on them. You cannot see dust particles all the time. Therefore time your filter changes to protect your family or co-workers from any breathing disorders.

What are the types of air conditioning filters?
- These filters have best efficiency among all types of filters.
- The efficiency is more than 99.97%.
- They can restrict dirt particles of sizes 0.3 micrometer at 85 liters per minute.
- They can work also for highly hazardous aerosols such as radioactive and highly toxic particles.
- They are used in hospitals, isolation rooms, and computer chip manufacturing areas. Actually, they are used where absolute filtration is required.
- You can use them in your home if cost is not a big issue.
Aluminum air filters
