Can Air Purifier's HEPA Filter Can Be Washed?

Have you ever seen or heard of the term HEPA filter in many household products? HEPA filters have long been used in household appliances to filter the air, making it cleaner from various types of air pollutants.

For those who have never heard of a HEPA filter, a HEPA filter is a type of high-quality air filter that must meet certain criteria. Once all the criteria have been met, the HEPA filter can remove at least 99.97% of standard particles from the air such as dust, pollen, mold, bacteria, and small particles in the air ranging from large to small particles.

 

HEPA itself stands for High Efficiency Particulate Air. HEPA filters are a common component of air purifiers that filter and purify the air so that it is free from harmful particles that can easily enter the respiratory system when inhaled.

 

Products Equipped with HEPA Filter Technology

Generally, there are two types of household appliances that have adopted HEPA filter technology, namely air purifiers and vacuum cleaners. Both products can help families maintain their health, especially those with asthma and allergies, thus helping to reduce the risk of these conditions.

1. Air purifier

Air purifiers with HEPA filters are specifically designed to filter and eliminate air, dust, dirt, and various air pollutants that are harmful to health, including cooking odors, pet fur, etc. They are designed for long-term use with many health benefits for the family.

2. Vacuum Cleaner

Pet dander and dead skin cells, as well as bacteria, are commonly found on your home's floors and furniture. When someone walks over them or brushes against other objects, these particles may become airborne. They can also stick to your hands or the clothes you're wearing.

Vacuum cleaners with HEPA filters can collect and filter dust and other small particles from your home's floors and furnishings before they reach the air. This method cleans not only the furniture but also the air.

3. HVAC Air Purifier

HEPA filters are not only used in air humidifiers and vacuum cleaners but also in air purifiers that are installed through HVAC systems throughout the house. However, this system is rarely used in most homes in Indonesia. However, it is utilized in homes in several other countries.

 

HEPA Filter Function

The efficiency with which airborne particles are trapped determines the effectiveness of filters. HEPA filters are extremely effective at trapping particles of all sizes, and they can theoretically remove more than 99.97% of 0.3-micron particles. This is among the most difficult particle sizes to capture.

Combustion smoke, diesel smoke, and exhaust fumes or smog all contribute to the formation of particles with diameters of up to 0.3 micrometers. Because of their small size, these particles can easily enter the lungs during inhaling.

On the contrary, particles that worsen allergies, such as pollen, are typically 10 microns in size and can be collected by filtering systems in the body like the nose and throat. This is why HEPA filtration is so crucial in capturing the very small 0.3-micron particles.

 

Can HEPA Filter Be Cleaned?

Filters are usually cleaned after noticing a buildup of dust or particles that make the HEPA filter appear gray or dirty, or if the airflow through the filter decreases. However, experts say that HEPA filters should be replaced rather than cleaned.

If you see a buildup of dust and dirt on the HEPA filter, all the particles accumulate. This can contain all the filtered particles like animal fur, vehicle exhaust gases, gas stoves, mold, etc.

If the HEPA filter becomes dirty, it is recommended to replace it with a new one. Most manufacturers also offer a recommended replacement period, usually requiring time between 6 to 12 months depending on usage duration. Some air purifiers have an indicator light that tells you when to replace the HEPA filter.

However, this is not always the best indicator of timing because the real reason for replacing the HEPA filter depends on the amount of accumulated particles and can vary greatly depending on the environment and duration of use. If the air purifier is on all the time or if the room is filled with dust or dirt, you will need to replace the HEPA filter more frequently.

 

Air Purifier with Best Air Purifier

Indeed, there are many air purifiers available in the market, but not all of them feature HEPA Filter technology. Usually, air purifiers equipped with HEPA Filters tend to be priced higher compared to those without HEPA filtration. One of the best air purifiers using HEPA Filter technology is the DREW Pure 5 Air purifier.

The DREW Pure 5 air purifier is capable of cleaning the air more easily, and its use is very straightforward, requiring just the press of a button. It features an Auto Mode that adjusts its functionality based on the air quality in the room.

No need to worry because the filter of the DREW Pure 5 air purifier is very easy to replace. The filter uses a HEPA 13 Filter and activated carbon, so it not only can filter the air from airborne pollutants but also eliminate odors, ensuring no unpleasant smells in the room.

The HEPA 13 Filter is capable of filtering air particles up to 99.97%, especially with the presence of 360-degree air filtration, enabling it to maximize air filtration throughout every corner of the room.

There is also a UVC light sterilization mode technology, where this feature is capable of killing viruses and various other air pollutants in the room. The use of this DREW air purifier does not consume a lot of energy, requiring only 38 watts, thus it can save on electricity costs.

 

Why Choose DREW Pure 5 Air Purifier

The DREW Pure 5 Air Purifier has a filter for filtering allergens; pet dander in the air can also be sucked into the air purifier, reducing the risk of allergies. This device can also help neutralize the smell of cigarette smoke that spreads in the air.

Sometimes, cigarette smoke often sticks to sofas, window curtains, clothes, and other objects, making the smell difficult to remove. However, with the DREW Pure 5 Air Purifier, it can help eliminate the stubborn smell of cigarette smoke even better, and also remove the smell of smoke in the air after cooking.

No matter how often a house is cleaned, hard-to-reach places will inevitably remain dusty, or dust from furniture will enter the air when it's being cleaned. This air purifier can help reduce the workload.

The DREW Pure 5 Air Purifier is said to be able to kill up to 99.97% of germs and bacteria in the air thanks to the installed HEPA Filter. Regular filtering can improve the quality of the air breathed, thereby helping to maintain lung health and stop the spread of disease-causing germs.
