Introduction

HEPA (High-Efficiency Particulate Air) filters have gained significance in recent years for their improving indoor air, especially for those with allergies, asthma, or patients sensitive to dust or other airborne particles such as pollen. HEPA filters are incorporated in air purifiers, vacuum cleaners, and the HVAC system. These filters are quite effective in trapping microscopic particles, further leading to less and cleaner air.

Nonetheless, one frequently asked question is if it is possible to wash a HEPA filter that has been put to use. Because maintaining its effectiveness is important, users always wonder if a HEPA filter can be cleaned up to allow for the maximum utilization of a filter without having to give up any requirements on its effectiveness. We’ll discuss the cleaning process, washable HEPA filters, and non-washable HEPA filters, as well as their duration for replacement, in this article.

What is a HEPA Filter, and How Does It Work?

HEPA filters are constructed to collect at least 99.97% of particle sizes from 0.3 microns and above. This includes pollen, house dust mites, animal hair, mold, and spores, as well as several bacteria and viruses. Densely woven fiber mats or batts made into a HEPA filter create a dense webbing through which air is allowed to short-pass while trapping all particles. HEPA filters help to prevent contamination in their intended environments to enable healthy air.

HEPA filters are found in many pieces of equipment, such as air purifiers, HVAC units, and vacuum cleaners. They are particularly crucial for households, offices, and medical facilities due to the critical importance of having clean air surrounding living and work environments.

Can You Clean a Used HEPA Filter?

It is significantly influenced by the kind of filter you have. Let’s consider its two types, washable and non-washable filters.

Cleaning Washable HEPA Filters: 

Water can be used to rinse washable HEPA filters clean. Here are some tips on cleaning the washable HEPA filter without damaging it:

  • Remove the filter:  Follow the manufacturer’s instructions to remove the filter from the device with care.
  • Rinse with Water: Place the filter in tap, cold water. Do not apply hot water or soap to the filter, as they will destroy it. Also, it helps to rinse the filter from the clean side to the dirty side to avoid seeping the particulates deeper into the fibers of the filter.
  • Reinstall the filter:  When the filter has completely dried, kindly put it back in place as per the manufacturer’s direction.

When Should You Replace a HEPA Filter?

A HEPA filter is among those apparatuses that, no matter how much care you give it, there comes a time when replacement is inevitable. Below are some signs that it is time to replace your filter:

  • Decreased Airflow: There could be a simple reason that the airflow within your air purifier or even the vacuum cleaner has diminished, which means that the HEPA filter is clogged and needs to be replaced.
  • Unusual Odors:  A damaged HEPA filter may emit bad smells due to trapped dirt particles inside. When your device releases a damp or old smell, it is probably time for a new filter.
  • Visible dirt and debris:  It would be wise to replace the filter when there is a notable pile-up of dirt on the filter and also when changes cannot be observed even after cleaning.
  • Manufacturer’s Guidelines:  Adhere to the filter replacement schedule prescribed by the manufacturer. This may change depending on usage; however, most HEPA filters should be changed from six to twelve months.

Types of HEPA Filters

HEPA filters are very important in containing airborne particles and thus the indoor air pollution levels.

In this regard, HEPA filters vary in shape and function based on their applications and efficiency. Here is an outline of the primary categories:

1. True HEPA Filters

A HEPA filter is tested by U.S. Department of Energy standards at 99.97% efficiency in trapping particles that are at least 0.3 microns in size including dust, pollen, spores, and pet hair, among other allergens. 

In fact, actual HEPA filtration is often placed in air purifiers, vacuum cleaners, and central heating and cooling systems. As such, people with allergies or who are concerned about the quality of indoor air will not be able to identify a problem locating this type of filter.

Their ability to filter out microdust particles less than 10 microns makes them highly recommended for home and office settings.’

2 H13 and H14 HEPA Filters

H13 and H14 filters represent a higher efficiency category within the HEPA filter classification.

  • H13 Filters:  A bacterial filter can even trap 99.95% of impurities sized 0.1 micron and above. Such filters are usually installed in air systems that are regularly maintained and used in institutions such as hospitals, laboratories, and cleanrooms where the level of air cleanliness is a priority.
  • H14 Filters: H13 filters and H14 filters enhance filtration efficiencies by capturing 99.995% of particulates, even as small as submicron particles. Such filters are useful in extremely clean conditions, e.g., manufacturing and research plants in pharmaceutical industries where clean air is an absolute necessity.

3. Absolute HEPA Filters

It is the HEPA absolute filter that surpasses the conventional HEPAs, which exclude 99.97% of all the particles that have a size starting from 0.3 microns. Usually, these filters are used in particular spheres and industries, for example, in the clean rooms and operating theaters where the air purification criteria are the highest.

HEPA filters are made of closely taped fibers, which act as a barrier against contaminants and toxins present in the air. Therefore, they are suitable for use in industries and companies where the air quality is of high standard. Their structure is designed in a way to ensure that tiny particles of dust and other airborne diseases are well trapped, preventing them from getting into the air.

FAQ

Can you clean a non-washable HEPA filter?

Hypoallergenic filters that cannot be washed must not undergo water cleaning. Only surface vacuuming or tapping to get any debris out might be done but will not make it work as new again.

Can I use soap or detergent to clean a HEPA filter?

My recommendation would be not to utilize cleansers like soap or detergents to service HEPA filters. For washable filters, a rinse with cold water is usually all that is required. Non-washable filters, on the other hand, ought to be kept away from water completely.

Conclusion

You can opt for a used HEPA filter, but the capability all depends on the filter that you’ll be using. In case you are using washable HEPA filters, just rinse them and reuse them; on the other hand, if using non-washable filters, you should immediately replace them once they are clogged.

Cleaning your filter may prolong its life, but at some point, even HEPA filters need replacement to ensure prime quality in the air. Following the guidelines given by the manufacturer and cleaning or replacing your filter as necessary, you can be assured that your device will provide clean, healthy air for your home or workplace.
