Here’s a quick tip right out of the gate: to reset Blueair purifiers, simply unplug them, wait several seconds, and then plug them back in. Voila.
Whether you’re doing a hard reset or following manufacturers’ specific guidelines, resetting will typically take you out of whatever loop or hang you are stuck in.
However, when resetting your Blueair purifier, you’re probably interested in resetting your filter cycle light.

The Specific Steps to Reset Blueair Purifiers
First, we’re not providing a step-by-step guide to reset every Blueair purifier. They have between 15 and 20 different models.
If the following doesn’t work, you must either refer to your user manual or do a Google search using your specific model number.
Having said that, the steps indicated below should or could work for any Blueair purifier model.
Another thing to note is that different models have different colored lights. So what do those lights mean?
Reset Blueair Purifiers: Lights and their Meanings
If you have a Blueair model with only a red alert light, it’s a notification that it’s time to replace your filter — if the light is steady.
However, if you have the Protech model and the light is blinking, something needs to be fixed with your filter installation.
Make sure to reinstall it properly, and the light should stop blinking.
If you have a Blueair model with only an orange alert light, it also means it’s time to replace your filter.
Some Blueair purifiers have both a red and yellow light.
The differing colors indicate the age of your filter.
A yellow light appears when the filter is about five months old, reminding you that you’ll soon need to change it.
Once the light turns red, you’ve run out of time and must replace your filter immediately.
Now let’s get into those specific steps.
The Blueair Classic — and Most other Models
Turn on the unit and press and hold the filter replacement button for at least 10 seconds until the light disappears.
And that’s it!
However, as mentioned above, if this doesn’t work for your specific model, refer to your user manual or search Google for answers, including your unit’s model number.
Why Do You Need to Reset Blueair Purifiers?
Resetting Blueair purifiers — and many other brands and models, too, for that matter — is very common.
Because most of us need reminders to keep on schedule, especially for things that aren’t work or family related.
In those cases — assuming we’ve recorded it — we’ll get phone reminders and notifications.
The problem is that the notifications we get on appliances are often annoying. Otherwise, you wouldn’t see or pay attention to them.
But if you don’t know how to turn them off or reset them, they get even more annoying, right?
But that annoying notification is there for a reason.
Changing Your Filters is Very Important

If you’ve gone to the expense of buying an air purifier, it makes no sense not to replace the filter on schedule.
A dirty filter won’t clean your air anymore. And there is a good chance a dirty filter will eventually destroy the fan motor on your purifier.
And then all you have is a very big, expensive doorstop.
Let’s dig a bit deeper into the reasons why you need to maintain your filters.
Reduced Efficiency and Effectiveness
The first and most obvious consequence of not changing a filter on time is that it becomes clogged and can no longer capture particles as they float by.
The surface of a filter is created with millions of microscopic fibers, often made of fiberglass.
It’s a surface that airborne particles will stick to.
Once that surface is covered, nothing more can stick to it.
As the filter loses efficiency, there’s less airflow, leading to a significant drop in performance.
What does that mean to you?
About a 50% decrease in filtration levels equals a corresponding drop in air quality.
Additional Health Risks
Filters not only capture dust, but they also capture an array of microorganisms like mold, bacteria, and viruses.
And when you change your filter, you get rid of all those nasty things attached to it.
Of course, if you don’t change your filter, what you have is a breeding ground for even more mold and bacteria.
Those pollutants spawn more on the filter even if you’re not using your air purifier.
Remember, the purpose of an air purifier is to clean the air and benefit your health.
A dirty filter will do the opposite and can lead to increased allergies and other respiratory issues.
It Ends up Costing You More
If you don’t change your filter and simply turn off your purifier, it may cost you health-wise, but it won’t impact your budget.
However, if you don’t replace your filter and consequently reset your Blueair purifier, it will cost you more to run it.
Clogged air filters mean compromised airflow.
When that happens, the fan motor uses more energy to compensate.
The more energy it uses, the more it costs you.
And with rising energy costs, it would cost you more this year than it did last year — and probably even more next year.
So if your hesitancy to replace the air filter is because of a lack of funds, remember, if you keep using your air purifier, it’s still costing you money anyway.

How Often to Replace and Reset Blueair Purifiers Filters
Okay, now that you know why you should be replacing and resetting your Blueair purifier filters, what’s the recommendation on how often to do so?
In general, Blueair recommends that filters be changed every six months.
But that doesn’t mean you shouldn’t pay attention to your filter lights.
They will provide a more accurate indication of when to replace your filter.
