In modern life, air purifiers have become an indispensable solution to maintain clean and healthy air in living and working environments. The air purifier filter is an important component that helps remove harmful agents in the air. So what is an air purifier filter? What types of air filters are there? Let’s find out the information in the article below.
1. What is an air purifier filter?
The air purifier filter (air purifier filter) is an important component in the machine, helping to clean the air by removing dust particles and other pollutants. Together they work to improve air quality in living and working environments.
After the air is sucked into the machine by the fan, the air will pass through the filters in turn, where each filter will perform a function and after the air has been cleaned, it will push the clean air out into the environment.
2. Classification of air purifier filters?
Air purifier filters are often classified based on material type and filtration features. There are 3 main types of filters commonly used by companies:
Pre-filter, also known as pre-filter, is the initial filter, usually a layer of mesh or fiber membrane. Used to remove large dust particles, pollen, fur and other solids in the air. The pre-filter helps protect other filters from clogging and prolongs their lifespan.
Activated carbon filter: This is the second most important filter of the air purifier. This filter uses activated carbon to absorb organic and chemical substances found in the air, such as toxic compounds, odors, and smoke.
HEPA filter: is the most advanced and important type of air purifier, developed to remove small particles from 0.3 microns in size with a filtration efficiency of over 99.97%. This includes bacteria, germs, pollen and microscopic dust particles that will all be cleaned.
In addition to the above 3 filters, some air purifiers also integrate other filters such as: nano filter, UV filter, negative ion filter…
3. How to clean different types of air filters
To ensure the machine operates efficiently, it is important to clean the filter periodically. Because the structure and materials used to make each filter are different, the cleaning method for each type of air filter is also different.
Coarse filter: Unlike other filters, you can clean this filter with clean water. If the filter is too dirty, you can use a little cleaning solution to clean residue and dirt.
For the remaining air filters, to clean you should use a vacuum cleaner or soft brush. Absolutely do not expose these filters to water as this will affect the structure of the filter, affecting the filtration efficiency.
4. When to replace the air filter
The time to replace the air filter depends on the type of filter, the level of air pollution, and the frequency of use of the air purifier.
For pre-filter: The life of the pre-filter is tied to the life of the machine, so there is no need to replace this filter. However, you need to make sure to clean the filter periodically 1-2 times/month.
Activated carbon filter: Change time depends on the level of use of the air purifier and living environment. Normally, the frequency of replacing activated carbon filters is from 6 – 12 months. However, there may be special cases when an earlier or later replacement is required.
The HEPA filter is the most important filter layer in the air purifier. HEPA filter replacement time is usually about 12 to 24 months, depending on the level of air pollution and purifier capacity. Changing the HEPA filter regularly will ensure the air purifier operates effectively and provides healthy fresh air to your living space.
In short, the air purifier filter is an important component that helps remove harmful agents and maintain clean air. With the combination of different types of filters, air purifiers make an important contribution in creating a healthy and comfortable living and working environment.
