Here is how to ensure your Winix Filter is free of obstructions and issues:

Please note that these filters should not be washed with any detergents, so use regular water instead.

If you have a True HEPA Filter, never wash or reuse it in case it has been degraded.

While the filters are removed, take your time to wipe the internal chamber where the filter sits from dust and debris.

Doing this will ensure no residual leftover dust will be reabsorbed into your clean filter.

Note: Pay attention to the type of filter your Winix uses; some filters are not washable.

Step #2: Inspect for Vibrations

Vibrations can be caused if your Winix is positioned incorrectly, causing a high-pitched mechanical sound.

To ensure your device is running within normal conditions, you have to check the Winix setup.

Here is how to check for causes of vibrations in your Winix air purifier:

  • Always place your Winix air purifier on an even surface without any tilting.
  • Avoid having the Winix device placed on a carpet, as the fabric can interfere with operations and cause static charges.
  • Check the feet of your Winix air purifier for obstructions or built-up debris, as these could change the elevation of your device and make it uneven.

Here is how to check your Winix power delivery for issues:

  1. Start by disconnecting your Winix air purifier and thoroughly examining its power cable along the entire length. 
  2. Check if the prongs are misaligned, loose, or have parts missing. 
  3. If damage is found, replace the entire power cable unit.
  4. Try using a different electrical outlet to connect your Winix purifier.
  5. Use a surge protector on a suitable power strip to help filter electrical fluctuations.
  6. Check if the electrical outlet you use is properly grounded. For this step, you need a functioning multimeter to check the current of your power outlet.
