How To Clean HEPA Filter

High-Efficiency Particulate Air filters, or HEPA filters, in short, are one of the most superior forms of air filters used in your house. They have been developed to keep the air of your house clean and fresh by capturing pollen, dust particles, pet hair, and even the minute particles present in the air. These kinds of filters come with extraordinary efficiency since they can capture 99.97% of particles which can be as tiny as 0.3 microns.

However, one of the main problems with these air filters is that as time passes, they get dirty very quickly since all of the dust particles collect and eventually clog or block the filter. That's why it's very important to clean them. It not only keeps them functioning properly, but it also extends their lifespan. Furthermore, an unclean filter might cause your devices to work harder than necessary, which may lead to issues later on. Interested in cleaning your HEPA filter without causing any harm to it? If yes then you are at the right place since in this blog you will come to know about the entire cleaning process of HEPA filters.

Understanding HEPA Filters

HEPA filters, or high-efficiency particulate air filters, are excellent air filters for air purification. These filters capture almost 99.97% of particles present in your indoor space, which can be as tiny as 0.3 microns. A micron is a tiny particle that is so small that it cannot be easily seen by the human eye. Therefore, HEPA filters are excellent in capturing mold, dust, pollen, pet hair, and even some germs and viruses.

HEPA filters function by passing air through a thick fiber layer. As the air passes through this thick fiber layer, the particles present in the air are caught by it, and the clean and fresh air flows through, stopping all the impurities from passing through. HEPA filters can be found in air conditioners, vacuum cleaners, and air purifiers. They help in improving the quality and health of the air in your living space.

Types Of HEPA Filters

Here are the different types of HEPA filters based on the cleaning. There are two main types of HEPA filters: washable and non-washable.

  • Washable HEPA Filters

These filters are designed to be cleaned and used again and again. Although frequent cleaning of these filters may cause them to lose some of their effectiveness over time, their washable feature makes them a more affordable choice. They are less frequently used in high-efficiency applications.

  • Non - Washable HEPA filters

Non-washable HEPA filters are designed to be used just once and need to be changed when they clog or after a specific amount of time. Since cleaning is not an option, these filters continue to function effectively for all of their lives.

Type Of HEPA Filters
HEPA Filters Washable Filters Or Non Washable Filters
True HEPA Filters Non Washable Filters
Ultra Low Penetration Air (ULPA) Filters Non Washable Filters
Medical-Grade HEPA Filters Non Washable Filters
HEPA-Type Filters Non Washable Filters
Washable HEPA Filters Washable Filters
Activated Carbon HEPA Filters Generally Non-Washable, Unless Specifically Stated
Carbon-HEPA Hybrid Filters Some Models Are Washable Filters

In places where maintaining high air quality is a priority, these people usually use non-washable air filters since they are more efficient and longer-lasting as compared to washable air filters which may be short-term cost-effective.

How To Tell If Your HEPA Filter Is Washable:

If you want to know whether your HEPA filters are washable or non-washable, then one of the easiest ways is to check for the manual given along with the HEPA filters. In the manual, it will be clearly stated whether you can wash your HEPA filters or not. Some filters will indicate that they must be changed, while other filters clearly mention that they are "washable." It is always advisable to always follow the manufacturer's directions if you're not aware.

Tools And Materials Required For Cleaning HEPA Filters

Some of the basic tools and materials that you need to collect once you plan to wash your HEPA filters are:

1. Soft brush
2. Vacuum cleaner with hose attachment
3. Mild detergent or soap (if applicable)
4. Water source
5. Soft cloth
6. Gloves (optional)

    Step-By-Step Guide

    Step 1: Turn Off The Device And Remove The Filter

    Always make sure that the device has been unplugged and switched off before you start cleaning the HEPA filter. This step is very important so that you can protect yourself from any electrical issues. Carefully remove the HEPA filter after turning off the device. To remove the filter without harming it, you can follow the directions that are stated in the manual.

    Step 2: Inspect The Filter

    After removing the HEPA filters, you can examine them carefully. You can check for the dust and dirt that has been collected in the HEPA filter and also look for any holes or signs of wear and tear. It may be time to replace the filter rather than clean it if it is really dusty or damaged. If the filters are washable and everything appears to be okay, then you may continue with the cleaning process.

    Step 3: Cleaning Process Of HEPA Filters

    Here is a complete cleaning process of HEPA filters.

    • Wash The Filter: Wash the filter with cold water first. When you wash the filter, hold it in such a way that the water flows from the cleaner side to the dirty side. This will provide a more thorough cleaning of the dust and grime. You need to be very careful while you are washing the filter.
    • Brushing Off Dirt: If you still find that dust and debris are stuck to the filter then you can use a delicate brush, such as a tiny toothbrush, to gently remove all the dust particles present. This is helpful in removing any remaining pieces of dust or dirt. Just be careful that you do not scratch too hard on the filter since that might damage the filter.
    • Using Soap (If Needed): You can use a very little mixture of mild soap and water to clean the filter if it's really dirty. To ensure there is no soap remaining, gently wash it with soapy water and then give it a good rinse. Rinse well because soap residue might impact the filter's function.

    Step 4: Dry The Filter Completely

    It's important to completely dry your filter before reinstalling it into the device. Allow the filter to air dry in a place with enough ventilation. Before putting it back in, make sure there is no moisture left behind since any moisture can lead to the growth of mold or mildew, which might have an adverse effect on the filter, and then it can also harm the quality of the air in your indoor space.

    Step 5: Reinstall The Filter

    Now you can carefully reinstall the filter in the system once it has been cleaned and dried. To ensure effective operation, make sure the filter is securely and properly positioned. The filter might not work as effectively as it should if it is not set up appropriately. Before restarting the device, make sure the filter is placed correctly.

    Common Mistakes to Avoid While Cleaning Your Filter

    When cleaning your HEPA filter, be careful not to make these common mistakes:

    • Using Harsh Chemicals Or Rough Tools: When cleaning your HEPA filter, stay away from strong chemicals and hard scratching tools like steel wool. These have the potential to harm the filter and reduce its capacity to capture particles. To keep the filter in good condition, use gentle tools like a soft brush and light soap.
    • Reinstalling A Moist Filter: If you find that your air filter is slightly moist or has little moisture on it, then avoid placing it back into the system. Due to a moist filter, there can be the presence of mold or mildew that could have a negative impact on the quality of the air. Always wait until the filter is totally dry before reinstalling it in your HVAC system or air purifier.

    How Often Should You Clean HEPA Filters?

    Generally, HEPA filters should be cleaned every one to three months, while exactly when to change your filters can differ based on a number of factors. You might need to change your filter more frequently if you live in areas where there is high pollen all around. Since pollen can accumulate and clog the filter quickly, as a result, it will decrease the efficiency of the filter. Pet owners also need to change their filters more regularly since pet flakes, fur, and hair may clog them quickly.

    The same applies to residences in dusty locations, such as those near construction sites or where dust gets collected more frequently. In such situations, you need to regularly clean your air filter every 1-2 months. You can also check the filter since there are some signs through which you can detect whether the air filter is working properly or not. Some of the signs are that there is a reduction in airflow, your energy bills will increase, and you may start having respiratory issues. All these things indicate that the filter is unclean and should be cleaned or replaced.

    Does Cleaning A Hepa Filter Restore Its Original Efficiency?
    Cleaning is not an ideal solution, although it can make a washable HEPA filter work better to some extent. As time passes, these filters can also degrade and become less efficient at capturing tiny particles. Vacuuming or washing the filter may improve its overall appearance and airflow, but it won't restore its original condition. To maintain the highest level of air quality, you will have to replace it.
    Can I Use A Hair Dryer Or Heater To Dry A Hepa Filter?
