Explore the intricacies of HEPA standard filters in air purifiers

Air purifiers using HEPA filter membranes are favored for their ability to effectively eliminate fine particles, dust, bacteria, viruses, and other pollutants in the air. Join Mytour Supermarket today to delve into the details of HEPA standard filters in air purifiers through the following article!

Explore in-depth the HEPA standard filters in air purifiers

HEPA (High Efficiency Particulate Air) standard filter is widely used in air purifiers and air conditioning systems.

According to research, a HEPA filter is designed to remove dust particles, pollen, bacteria, and other small particles sized 0.3 microns and above.

1.1. Structure 

HEPA standard filter is constructed like a mesh formed by the random arrangement of many glass fibers with very small diameters, ranging from 0.5 - 2 micrometers. These fibers are then tightly bonded together, forming a thick filter mesh.

This fine mesh system allows the HEPA filter to capture a large quantity of ultrafine dust particles, particles that other conventional filters cannot remove.

1.2. Operating Mechanism

The operating principle of the HEPA filter membrane is simple: after dust is sucked into the air purifier, it first comes into contact with the coarse filter. Next, the dust is drawn into the mixed filter membrane.

Operating Mechanism

The filtration process consists of four main stages: yellow dust filtration, Aldehyde air filtration, odor removal, and scent filtration. After the filtration process is completed, the dust is led to the odor removal filter membrane for the final filtration stage.

1.3. Functions of HEPA Filter in Air Purifiers

HEPA filters in air purifiers can remove fine particles such as PM2.5, PM10, and larger particles in the air. Additionally, they are capable of eliminating bacteria, viruses, mold spores, pollen, and allergens such as pet dander, pollen, etc., providing clean and fresh air.

Functions of HEPA Filter in Air Purifiers

To meet HEPA standards, a filter must meet certain efficiency requirements. According to European ISO standards, the filter must be able to remove 99.95% of particles sized 0.3 micrometers. The efficiency of filtering larger and smaller particles must also be correspondingly high.

HEPA filters can retain substances such as pollen, dust, soil, moisture, bacteria (ranging from 0.2 to 2 micrometers), viruses (sized from 0.02 to 0.3 micrometers), and fog particles (ultrafine water droplets that can exist in liquid or solid form, ranging from 0.02 to 0.5 micrometers).

Requirements for Achieving HEPA Standard Filters in Air Purifiers

HEPA standards emerged in the 1950s and have become a benchmark for the quality of efficient air filtration systems. HEPA standard filters are commonly used in stringent environments such as electronic manufacturing plants, nuclear facilities, and essential goods production areas.

As the production cost of HEPA filter membranes has decreased, air filtration devices using HEPA standard filters are now widely used in households and even applied in automobiles.

Humid weather, or in other words, when the air is moist, can cause discomfort and increase the risk of bacterial, bacterial, and mold growth. In such cases, other devices such as humidifiers, dehumidifiers, or air conditioners are needed to regulate and maintain the humidity at an appropriate level in the air.

It is evident that HEPA standard filters are highly effective in filtering dust and small particles such as pollen, spores, household dust, mold, bacteria, viruses, and other particles. However, they are not designed to alter humidity or effectively remove moisture from the air.

HEPA Standard Filters Can Help Control Humid Weather

However, for spaces with imbalanced humidity and particularly high dust density, using HEPA filters in conjunction with humidifiers, dehumidifiers, or air conditioners can help improve the environment and keep the air fresh and healthy.

Step 1: Turn off the air purifier and consult the user manual

Before cleaning, ensure that the air purifier is completely turned off and unplugged.

Refer to the user manual of the air purifier to learn how to remove the HEPA filter from the machine. Each machine may be designed differently, and the disassembly process may vary.

Step 2: Remove the HEPA Filter

According to the manufacturer's instructions, remove the HEPA filter from the machine. Handle with care and gentleness to avoid damaging the filter.

Step 3: Inspection and Cleaning

HEPA filters come in two types: washable (indicated as “Washable”), and non-washable. Inspect the HEPA filter to assess the level of dirt, as well as to determine if the filter is washable.

If the non-washable filter is dirty or has residue, you can use a small brush, soft brush, or soft vacuum to clean dust particles and residue on the filter. Be careful not to damage the filter.

For washable filters, you can rinse it with clean water or use a soft brush to remove stubborn dirt. Finally, ensure that the filter is completely dry before reinstalling it into the machine.

Step 4: Reinstall the Filter

Once the filter has been cleaned and completely dried, reinstall it into the machine following the reverse process instructions. Ensure that the filter is properly positioned and securely locked.

Step 5: Check and Power On the Machine

After cleaning the HEPA filter, check to see if the filter has been installed correctly and securely. Turn on the air purifier to check if it is operating normally.

Given the opportunity, users may invest in air filtration devices equipped with HEPA standard filters. Purchasing an air purifier with this filter not only benefits in improving air quality but also ensures health safety for you and your family.

Investing in air filtration devices with HEPA standard filters is possible

As HEPA filtration technology has reached standard levels and manufacturing costs continue to decrease, users have increasingly more options for advanced air filtration devices at affordable prices.
