Understanding Your Blueair Filters

Blueair purifiers utilize various filter technologies, each requiring a specific cleaning approach. Knowing your filter type is crucial for effective maintenance.

Particle Filter (Fabric Filter)

This is the primary filter in most Blueair models, capturing dust, pollen, pet dander, and other airborne particles. It’s washable, making regular cleaning essential.

Carbon Filter (Activated Carbon Filter)

Designed to absorb odors, gases, and VOCs, carbon filters aren’t washable. However, they benefit from occasional vacuuming to remove larger particles that can clog the carbon.

HEPA Filter (High-Efficiency Particulate Air Filter)

Some Blueair models incorporate HEPA filters for superior particle removal. These filters are not washable and require replacement when they become saturated. Attempting to wash a HEPA filter will damage it and render it ineffective.

Cleaning Your Blueair Particle Filter

This section focuses on cleaning the washable particle filter, the most common maintenance task for Blueair purifiers.

Materials You’ll Need

  • Vacuum cleaner with brush attachment
  • Mild dish soap
  • Lukewarm water
  • Soft brush or sponge
  • Clean cloth
  • Spray bottle (optional)

Step-by-Step Cleaning Process

Step 1: Filter Removal

  1. Turn off and unplug your Blueair purifier.
  2. Locate the filter compartment (refer to your Blueair model’s user manual).
  3. Carefully remove the particle filter.

Step 2: Dry Vacuuming

  1. Using the brush attachment on your vacuum cleaner, gently vacuum the outside of the filter. This removes loose dust and debris. Work in a downward motion to avoid forcing particles deeper into the fabric.
  2. Vacuum the inside of the filter as well.

Step 3: Washing the Filter

  1. Fill a sink or tub with lukewarm water and a small amount of mild dish soap.
  2. Submerge the filter in the soapy water and gently agitate it to loosen dirt and grime. Avoid harsh scrubbing, which can damage the filter fibers.
  3. Rinse the filter thoroughly under running lukewarm water until all soap residue is removed. Continue rinsing until the water runs clear.

Step 4: Drying the Filter

  1. Gently shake off excess water. Do not wring or twist the filter.
  2. Allow the filter to air dry completely. This can take 24-48 hours depending on humidity. Do not use a hairdryer or place the filter in direct sunlight.
  3. Ensure the filter is completely dry before reinstalling it in the purifier.

Step 5: Reinstallation

  1. Once dry, carefully reinstall the particle filter into the purifier.
  2. Plug in and turn on the purifier.

  2. Using the brush attachment on your vacuum cleaner, gently vacuum the outside of the filter to remove accumulated dust.
  3. Reinstall the carbon filter. Do not attempt to wash or use water on the carbon filter.

Pro Tips for Blueair Maintenance

Blueair purifier placement best practices

  • Pre-filter: Consider using a pre-filter (washable fabric placed over the particle filter) to capture larger particles and extend the life of your main filter.
  • Location Matters: Place your Blueair purifier in a central location with good airflow, away from obstructions.
  • Avoid Harsh Chemicals: Never use harsh detergents, bleach, or abrasive cleaners on your filters.
  • Filter Reset: Many Blueair models have a filter replacement indicator. Reset this indicator after cleaning or replacing the filter (refer to your user manual).
  • Monitor Air Quality: Use an air quality monitor to track the effectiveness of your purifier and determine the optimal cleaning/replacement schedule.
  • Run on Auto Mode: Allow your Blueair to automatically adjust fan speed based on air quality for optimal performance.
  • Regular Dusting: Regularly dust surfaces around the purifier to minimize dust buildup.

When to Call a Professional

  • Persistent Odors: If your purifier is unable to eliminate persistent odors, even after replacing the carbon filter, there may be an underlying issue.
  • Unusual Noises: Strange noises coming from the purifier could indicate a mechanical problem.
  • Complete Malfunction: If your purifier stops working altogether, contact Blueair customer support or a qualified appliance repair technician.
