How to clean Blue air purifier for a fresher home?

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

In this blog post, I’ll be looking at how to clean a blue air purifier so that it can continue to provide you with the clean air you need. Read on to learn more about the best ways to keep your blue air purifier clean and working efficiently.

Why should you clean it regularly?

Before moving into the cleaning procedure, it’s important to know why you should clean your purifier regularly.

Cleaning the purifier regularly is important for a few reasons. First, it helps keep the filter clean and able to capture more particles. Regular cleaning also helps maintain optimal airflow, allowing the machine to run efficiently and effectively. Lastly, it helps to prevent the build-up of bacteria and other contaminants that can reduce air quality and create unpleasant odors.

Steps to clean Blue Air Purifier correctly.

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 in cleaning your air purifier:

Step 1: Disconnect from the power source

Before cleaning the filter, unplug your device from the wall outlet or charging station. Also, turn off your purifier 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 that 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, to clean the Blueair purifier pre-filter, follow the below steps:

  • 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, you must 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.
