How to clean Blue air purifier in Just 2 Minutes?

If you own a blue air purifier, you know how important it is to keep it clean and functioning properly. Poor air quality can be a major health hazard, and a dirty air purifier can lead to many problems.

In this 2 minutes guide, I will break down the steps you need to do to properly clean your Blue Air Purifier.

Here we go! Let’s dive into it…

Why should you clean it regularly?

Cleaning a purifier regularly is important for a few reasons.

First, it helps keep the filter clean and able to capture more particles. Then it helps to maintain optimal airflow, allowing the machine to run efficiently and effectively.

And finally, it prevents the build-up of bacteria and other contaminants that can reduce air quality and create unpleasant odors.

Steps to clean Blue Air Purifier correctly.

Before writing this guide, I looked at user guides for Blue air purifiers to come up with this cleaning overview.

Here are the basic step-by-step guidelines to follow:

Step 1: Disconnect the purifier from the power source

Before starting the process, unplug the device from the wall outlet or charging station. Turn off it completely.

This will help speed up the process and make your job safer, lowering the risk of an electric shock.

Step 2: Clean the pre-filter

There are two filters in a Blue air purifier. One is called a washable pre-filter, and the other is the HEPA (main) filter, which is not washable.

Remember, you can only clean the pre-filter, not the HEPA-Filter. You must replace the HEPA (main) filter if it’s dirty or damaged.

However, here’s how to clean the pre-filter:

  • First, carefully push the top cylinder down while rotating counterclockwise and remove it from the unit.
  • Open the pre-filter panel and remove the pre-filter.
  • Now wash the pre-filter in the washing machine and dry it completely.
  • Once done, place the pre-filter back onto the unit.
  • And finally, push the top cylinder down, at the same time rotating it clockwise to secure it back into the lock.

Sometimes you may face a red light issue on your purifier, and that’s why I wrote a separate blog post to fix this red light issue. (You can check it.)

Step 3: Check the HEPA filter and replace it if needed.

After cleaning the pre-filter, check the main filter to see if it’s damaged or clogged.

If the filter is damaged or heavily clogged, replace it with a new one, as HEPA filters can’t be washed.

Blueair suggests that users should change the filter every 5-6 months. According to Blueair, you should be serious about the filter and must replace the filter at least two times a year to get optimal functionality.

Step 4: Wipe off the air purifier

Once done everything, take a soft, dry cloth and wipe all dust from the surfaces of the air purifier, including the control panel, filter grille, and exterior housing.

Never use harsh chemicals or abrasive cleaners on any air purifier part.


Q. How often should I clean my Blue Air Purifier?

This depends on your model and how often it is used. However, to ensure peak performance, you should clean the purifier and its filter every two to four weeks.

Q. How often should I replace my purifier’s filter?

According to Blueair, you should replace your purifier filter every six to eight months. However, depending on how frequently you use it, you may need to replace the filter more frequently.

Q: How do I know when it’s time to clean my Blue Air purifier?

The Blue Air purifier has a filter replacement indicator that will alert you when it’s time to clean or replace the filters. You can also check the device’s performance by monitoring the air quality in your home.

Q: What happens if I don’t clean my Blue Air purifier?

If you don’t clean your Blue Air purifier, the filters can become clogged with dust and debris, reducing their effectiveness.

This can lead to poor air quality in your home and potentially exacerbate allergies and respiratory issues.
