How to do a “Filter Life” reset on your Shark air purifier

Once you have replaced the filters in your Shark air purifier, you will need to complete a “Filter Life” timer reset by completing a few simple steps.

Shark air purifiers are a convenient way for you to keep things like allergens, pollen, dust and other particulates at bay.

However, just because these air purifiers are designed to be as user-friendly as possible, it does not mean that they do not require any maintenance.

The “Filter Life” reset process

And if you have had your Shark air purifier for a few years, you will already know that one of the most important maintenance tasks to complete on a fairly regular basis (about once every 6 to 12 months), is replacing your air purifier filters.

You will know that it is time for this replacement when the “Filter Life” button on the control panel starts to flash.

Fortunately, all that this process really requires is that you replace your filters and then reset the “Filter Life” timer, as in the processes outlined below.

Replacing Shark air purifier filters

Every Shark air purifier works in its own, unique way. And as a result, the filter replacement process differs slightly from one model to the next.

However, in broad terms, this process only usually involves a few simple steps, which can be summarized as follows:

Process Description
Step 1 Turn the air purifier off and unplug it from the outlet
Step 2 Access the air purifier’s interior filter and remove it
Step 3 Clean the inside of the air purifier with a microfiber cloth or a handheld vacuum
Step 4 Position the replacement filter in its place and ensure that it clicks securely into the compartment
Step 5 Replace any panels and ensure that the unit is returned to an upright position if necessary

Understanding the “Filter Life” percentage

Shark air purifiers provide you with lots of different information about the air in your room, but they also include a handy-dandy “Filter Life” percentage indicator which can help you keep track of the life cycle of your filters.

And, while you likely usually only notice this percentage when your air purifier is warning you that it is time for the filters to be replaced, you can actually check the “Filter Life” percentage at any time.

To do this, you simply need to press the “Filter Life” button on the control panel.

A brand-new filter should have a Filter Life percentage of 100% (as it is as the start of a new lifecycle), whereas an old filter that needs to be replaced will have a Filter Life percentage which is closer to 0% (as it nears the end of its lifecycle).

Checking this percentage regularly should help you to keep track of how long your air purifier will be able to operate effectively with its current filter.

Resetting the “Filter Life” timer

Once your “Filter Life” percentage reaches 0%, and you have gone through the process of replacing your old filters with new ones, you will have to reset the “Filter Life” timer on the machine to help you keep track of this new filter’s lifecycle.

The process to reset the “Filter Life” timer is as follows:

  • Step 1: Plug the air purifier back into the outlet and switch the unit on (by pressing the power button at the top of the unit or using the remote)
  • Step 2: The unit should recalibrate on its own
  • Step 3: Press and hold the “Filter Life” button for at least three seconds (this button is on the display panel)

If the Filter Life timer reset has been successful, you will hear a small beep and the Filter Life percentage will return to 100%.

Tips for extending the life of your air purifier filters

The lifespan of Shark air purifier filters will ultimately vary, depending on different factors like the frequency of use, your preferred settings, the environment that you live in and more.

But there are a few clever tips that could help you  if you want to make these filters last just a little bit longer. This includes things such as:

  • Ensuring that your Shark air purifier is run in Auto Mode or Eco Mode to guarantee that it is running as efficiently as possible
  • Keeping the air purifier fairly clean by removing any excess dust or dirt from the outside of the unit with a microfiber towel
  • Ensuring that you are cleaning the space around the air purifier fairly regularly
  • Fixing any leaks and cracks in your home which could be letting outside contaminants in
  • Ensuring that you are replacing your filters with Shark filters that are specifically designed for your model
