Selection of custom HEPA filters in different sizes

custom HEPA filters

With custom HEPA filters, you can choose the right size according to your needs. With customization, users can choose the right filter size according to their specific needs, such as space size, air flow rate, budget, and special needs (e.g. to deal with allergens, bacteria, viruses, etc.), which can improve the effectiveness and efficiency of the air purifier and prolong its service life.


Customized filters of different sizes

1、Standard size filter

This is the most common home air purifier filter size and is suitable for most homes and small to medium-sized spaces. They usually have high filtration efficiency and can effectively remove most pollutants from the air.

2、Small size filter

Small-size filters are usually suitable for small spaces or where a higher efficiency filter is required. They are usually lighter than standard-size filters, so they are more suitable for use in small spaces. In addition, some small-sized filters also have a higher filtration precision and can be more effective in removing particulate matter.

3、Large size filter

Large-size filters are suitable for large spaces or places requiring longer filtration time, such as shopping malls, offices, hospitals, etc. They usually have a larger filtration area and higher filtration efficiency, which can provide longer and more effective air purification. In addition, some large-sized filters also have an activated carbon layer that can adsorb more harmful gases and odors.


This is a detailed description of the different sizes of custom filters. These different sizes can be selected according to different space sizes and usage requirements to meet the specific needs of users. At the same time, choosing the right filter size can also improve the effectiveness and efficiency of the air purifier and extend its service life.


Factors to consider when choosing the right size

The following factors need to be considered when choosing a suitable filter size:

 1、Space size

Firstly, you need to determine the size of the space to be purified. The size of the filter should match the size of the space to ensure that the air purifier can effectively remove pollutants from the air. Smaller spaces require the use of smaller-size filters, while larger spaces require the use of larger-size filters.

2、Air flow rate

The airflow rate of the filter should match the power of the air purifier. This means that you need to choose a filter with enough filtration capacity to ensure that the air purifier works properly and does not reduce performance due to clogged filters.

3、Budget

The price of the filter will also affect the size of the filter you choose. Some of the more expensive filters may have higher filtration efficiency and last longer. Therefore, you need to choose the right filter size and brand according to your budget.

4、Special needs

In addition to the space size and airflow, you should also consider special needs. For example, if you have a history of allergies or suffer from respiratory problems, you may need to choose a more effective filter to reduce exposure to allergens and pollutants.


In addition to these few factors, you must consider filter installation and replacement. Some filters may require special installation tools and steps, so you need to choose the right filter for your environment and skill set. You also need to consider the replacement interval of the filter to ensure that the air purifier will keep running efficiently.


Advantages of custom HEPA filters

The advantages of customized filters are mainly in the following aspects:

1、Personalization

Customized filters can be tailored to the specific needs and preferences of the user, such as the size, performance, and material of the filter. This means that users can choose the right filter according to their specific needs, thus meeting individual requirements.

2、High-efficiency

Customized filters usually have higher filtration efficiency and are more targeted to remove airborne pollutants such as dust, pollen, viruses, bacteria, etc. more effectively. This improves the effectiveness and efficiency of the air purifier, thus better protecting the user's health.

3、Longer service life

Customized filters usually have higher filtration accuracy and a longer lifespan. This means that users can use the air purifier for a longer period without having to change the filter frequently, thus saving time and cost.

4、More adaptable

Customized filters can be tailored to suit different spaces and usage environments, thus better adapting to different needs and conditions. This improves the adaptability and reliability of the air purifier, thus better meeting the needs of the user.


Customized filters offer the advantages of personalization, high efficiency, longer service life, and adaptability, all of which can provide users with better indoor air quality and save time and costs.


Purchase and Installation Recommendations

  • When purchasing customized filters, users need to understand the performance and characteristics of various filters and choose the right brand and model according to their needs. Users can get more information by reading product manuals, checking product reviews, and consulting professionals. In addition, users also need to pay attention to whether the size of the filter meets the requirements of the air purifier to avoid installation errors.

  • When installing the filter, users need to follow the installation instructions of the air purifier to ensure that the filter is properly installed and secured. Users should also pay attention to safety issues and wear appropriate equipment, such as gloves and masks, to avoid accidental injuries. When replacing filters, users should contact a professional to ensure proper filter replacement and proper operation of the air purifier.
