When should air purifier filters be replaced?

Air purifiers have become an effective solution for improving the air quality in our living and working spaces. However, to ensure the efficient operation of an air purifier, it is crucial to regularly replace the air filters. In this article, we will explore the timing for replacing the pre-filter, activated carbon filter, and HEPA filter.

1. When should air purifier filters be replaced?

1.1. Timing for Replacing Pre-filter

The pre-filter is the first layer of filtration in an air purifier, designed to capture large dust particles, pollen, and hair in the air. The lifespan of the pre-filter extends along with the lifespan of the air purifier, so there’s no need to replace the pre-filter after a period of use.

If the pre-filter becomes excessively dirty or clogged, it can be removed and cleaned with water.

1.2. Timing for Replacing Activated Carbon Filter

The activated carbon filter functions to remove unpleasant odor-causing pollutants, hazardous chemicals, and smoke in the air. The timing for replacing the activated carbon filter is typically around 6 to 12 months, depending on the level of air pollution and the capacity of the filter. When the activated carbon filter becomes saturated, its absorption efficiency decreases, necessitating replacement.

1.3. Timing for Replacing HEPA Filter

The HEPA filter is the most critical filtration layer in an air purifier, responsible for removing ultrafine dust particles, bacteria, and viruses in the air. The timing for replacing the HEPA filter is usually around 12 to 24 months, depending on the level of air pollution and the capacity of the air purifier. Regularly replacing the HEPA filter ensures the efficient operation of the air purifier and provides healthy, clean air for your living space.

2. How to Replace Air Purifier Filters at Home

Replacing air purifier filters at home is a simple and straightforward task, but it requires following specific steps to ensure the replacement is done correctly. Below is a detailed guide on how you can replace air purifier filters at home:

Step 1: Identify the type of filter

First, identify the type of filter you are using in the air purifier. There are three common types of filters: pre-filter, activated carbon filter, and HEPA filter. Identifying the correct type of filter will help you purchase the right replacement product.

Step 2: Turn off the power

Step 3: Open the air purifier casing

Open the casing of the air purifier by removing screws or locking tabs. The process of opening the casing may vary depending on the type of device, so refer to the manufacturer’s instructions if you are unsure.

Step 4: Remove the old filter

After opening the casing, you will see the current filter installed inside the device. Remove the old filter by pressing or releasing any clips holding it in place.

Step 5: Install the new filter

Place the new filter in the same position as the old one and ensure it is correctly positioned and securely installed.

Step 6: Close the casing and power on the device

After installing the new filter, close the casing of the air purifier by reattaching screws or locking tabs. Then, turn on the power and check if the air purifier is operating normally after replacing the filter.

Regularly replacing air purifier filters is essential to ensure the efficient operation of the device. Refer to the manufacturer’s instructions to determine the appropriate filter replacement schedule for your specific type of filter and air purifier. By properly replacing pre-filters, activated carbon filters, and HEPA filters, you will ensure a healthier and safer living and working environment.
