Why Your Bissell Air Purifier Is Buzzing & How To Fix These Issues

Your Bissell air purifiers may make a loud buzzing noise if the air inlet is clogged. To allow free air circulation, the front of the machine must be at least a foot away from any walls or furniture.

Another reason why the air purifier could keep buzzing is if the filters are overly dirty. Filter-type air purifiers rely on the filter to collect pollutants from the air. Since the filter absorbs pollutants constantly, it would inevitably accumulate too much dirt after continuous operation. If too much dirt blocks the filter screen, it will increase the wind resistance and increase the noise.

Overloading can also cause the air purifier not to function properly and increase the noise it produces. Stronger purifying power is required for larger areas. 

Here are a few things you can check to get rid of the noise from your air purifier.

Check The Machine's Distance From Walls And Furniture

The front of the air purifier should be at least a foot away from walls or furniture to permit proper airflow circulation across the room.

If the machine is loud or whistling, the fabric front panel must be cleaned. Occasionally vacuum the front panel to get rid of collected dust.

Reset And Clean The Sensor

Run the machine for 10 minutes after cleaning it in order to reset its sensor.

To do this, you should:

  1. Unplug the machine.
  2. Remove the fabric front cover.
  3. Open the machine's left side door that leads to the particle sensor & remove the sensor screen and use a cloth or cotton ball to wipe it down.
  4. Remove the linked particle sensor to access the back of it. 
  5. With a vacuum, clean the particle sensor (front and back) & the inside cavity. Reinstall the sensor & sensor door.
  6. Let the machine run for 10 minutes to reset the sensor for an accurate reading.

Replace The Air Filters

Slow airflow is the main issue with blocked filters. Airflow decreases as particles build-up, which might result in higher purifier and electricity usage. Depending on how much the filter requires replacing, this may also strain the machine.

The air of the air purifier must pass through the filter screen. The machine will make a loud buzzing noise if the filter hasn't been changed or cleaned in a while; therefore, it should be replaced.

To do this, you should:

  1. Turn off or unplug the air purifier from the power source.
  2. Grip the bottom cover's handle and turn it clockwise until it unlocks, then pull it off to get to the filter.
  3. Remove the dirty filter and install the new filter in its place.
  4. Replace the bottom cover to align the arrows.

How Often Should You Replace Your Air Purifier Filter?

The life of your filter depends on how frequently you use your air purifier and the quality of the air in your home. If the white filter sheet in your purifier has turned gray or black, or if there is more dirt on it than usual, it may be time to replace your filter.

Bissell support recommends changing it every three months so the machine can continue to remove dust, pet dander, pollen, and odors from the air and you can breathe easily.

How Long Does It Take For An Air Purifier To Clean A Room?

This mostly depends on the air purifier's setting, the current air condition, and the room size. Your air purifier may take 30 minutes to clear the air in a smaller space. Expect it to take a minimum of two hours for larger rooms. 

However, this does not imply that your air purifier requires only two hours of operation. The only method to ensure the maximum air quality in a room or residence is to regularly run an air purifier. Your rooms will continue accumulating new pollutants; therefore, keeping your air purifier turned on is important.

Where Is The Best Place To Put An Air Purifier In A Room?

The best location for an air purifier is close somewhere in your breathing zone, but make sure the front panel is facing away from where your bed is. The device may be best positioned on a nightstand close to your bed, away from obstructions, to effectively remove airborne contaminants and supply clean air while you sleep.

Avoid positioning your air purifier against a wall or in a corner because this can block the air intake and slow down how quickly it can take in and clean the air in the room. Additionally, ensure that your air purifier is away from any devices, furniture, or anything that can obstruct airflow. Clear a gap of about three feet on both sides of the unit, if possible.

Do Air Purifiers Use A Lot Of Electricity?

Fortunately, air purifiers do not consume much electricity. They have a maximum wattage of anywhere between 40W and 200W. An air purifier can also operate at a lower 10–30 watt setting.

A purifier that runs continuously for 24 hours may sound expensive, but most only cost between $0.05 and $1.00 a day to run. Doing the math, that's a maximum of $7 per week.
