Alen Air Purifier Won’t Turn On? Here’s How To Fix It!

If you’ve been searching around to figure out why your Alen air purifier won’t turn on, you’re not alone; it’s a common problem that many users encounter, no matter what model they have. 

A purifier that won’t turn on can be incredibly frustrating, especially if you are trying to get rid of dust, dirt, pet dander, pollen, and other pollutants in your home. But no worries – there are several different troubleshooting strategies to help you restore your machine to full functionality quickly. Below, you will find advice and steps on how to fix the problem if your Alen air purifier is not working.

Why Alen Air Purifier Won’t Turn On? 

There are several different reasons why your Alen air purifier won’t turn on, and here’s a list of the most common:

Check the Power Cord

One possible reason for your problems with your air purifier may be that the power cord is not plugged in. If it doesn’t turn on even though it’s plugged in, there may be an issue with the appliance itself.

Check the Power Switch

If your air purifier isn’t working properly, you should check to see if the power switch is on. If it is not on, then it may be the problem. If it is on and still not working, there could be a problem with the unit itself.

Check if There is Any Damage to the Purifier

If you’re still having trouble with your air purifier, there may be damage to the unit. If the unit sustains any damage itself, like a broken panel or damaged fan blades, then this could be causing your machine not to turn on properly.

Check if There is Any Filter Problem

The common reason air purifiers don’t turn on is that there is no filter installed. The purifier will shut off to protect itself from overheating if it cannot draw in enough fresh air, so it may turn off if no filter is present. Ensure you have a HEPA or activated carbon filter installed before you plug in your machine.

Check Out the Impeller

If you find your Alen air purifier refuses to turn on or randomly switches off again, chances are it’s a problem with the impeller. The easiest way to fix it is by taking out one of your filters and emptying any dust that might be clogging up its works.

Check out Water Damage

One common cause of the Alen air purifier not turning on is moisture damage. When water damages your Alen air purifier, it’s usually easy to spot there will be puddles or wet spots nearby that indicate a problem. But you may also see signs of moisture in your Alen air purifier itself, like condensation on the top or side and a change in color. For example, if you have an Alen air purifier with a black top, you may notice that it’s turned a dark grey from water damage.

HEPA filter

Most models include a HEPA filter for trapping airborne particles as small as 0.3 microns. It is essential in allergy-prone households where pollen, pet dander, mold spores, and dust mites can cause chronic irritation. For example, one model (the Alen BreatheSmart) removes 99% of airborne particles such as pollen and pet dander from large rooms up to two stories high. 

 Charge Neutralizing property

Alen air purifiers emit negative ions, which help neutralize positively charged pollutants like dust and smoke. Others emit UV light which helps kill germs on surfaces around your home. 

Ventilation mode

Most models have a ventilation mode that helps you control the speed of airflow while maximizing the filter’s effectiveness. It is beneficial if you have ample space to clean or if you need to clear out odors from a room without interrupting normal operations.

Auto-off timer

Some models automatically turn off after a set period so that they don’t continue to run when no one is using them. It is beneficial for people who use their air purifiers for overnight cleaning or for those who are away from home for long periods of time.

How does the Alen air purifier work?

Alen Air Purifier Won't Turn On

Air purifiers come in two basic types: ionizers and HEPA filters. The difference between these two types of units is their filtration method and their level of effectiveness. Ionizers use an electrostatic charge to attract particles into their chambers, where an electrostatic process removes them. HEPA filters use a combination of high-efficiency particulate air (HEPA) filtration, active carbon, and UV light to remove bacteria, viruses, mold spores, pet dander, dust mites, pollen, and smoke particles, and other airborne contaminants from your home’s air.

The Alen air purifiers use both methods: it emits negative ions and utilizes a HEPA filter for particle removal. HEPA stands for High-Efficiency Particulate Arrestance. These filters are capable of removing 99 percent of the particles that pass through them, including pet dander, mold spores, dust mites, pollen, and smoke.

Alen Air Purifier Color Lights: What Do The Color Lights Mean?

  • When your Alen air purifier is operating correctly, a green light should illuminate in front of the power button on top of your device. If it isn’t lighting up, don’t fret; it’s likely because there isn’t enough power running to operate. Unplugging and plugging back in may fix it, but if not, you can easily reset your device by holding down both buttons simultaneously for 3 seconds until it blinks twice and restarts on its own. 
  • Red light indicates overheating: Your device has either been overused or placed too close to an outside heat source like a fireplace, radiator, etc. When your device gets too hot, the best thing to do is to unplug it and allow it to cool off before turning it back on again (you could also give it time in an area with cooler temperatures). 
  • The yellow light indicates no airflow detected. It could be due to several things: Your filter needs changing, your filter needs cleaning, your machine might need professional repair, etc. The simplest way to test whether any of these are true is by performing a quick sniff test. First, check all vents at the bottom base of the unit and then remove the lower grill altogether. Now place your nose directly over a vent hole and inhale deeply. If you smell anything other than clean air coming out, it’s time to change or clean your filter.

Why is my air purifier not working?

What is the difference between a HEPA filter and an activated carbon filter?

The HEPA filter is the most common filter used in air purifiers. It is also known as a high-efficiency particulate air (HEPA) filter. The HEPA filters are made from synthetic fibers that are able to trap 99.97% of all airborne particles as small as 0.3 microns in diameter. On the other hand, the activated carbon filters are made from natural materials such as coconut shells and coconut husks that can trap larger particles down to 0.3 microns in diameter (but not smaller).


When a person begins to notice that their air purifier is no longer performing as well as it once did, they tend to panic, thinking that it’s broken. However, most of these products have built-in filters, which must be cleaned and maintained regularly in order for them to continue operating at optimal levels. When people neglect to clean their units, one of two things happens: either allergen builds up in them and clogs up their filters, or debris from around your home gets into your unit’s ventilation system and interferes with its ability to produce clean air. Don’t worry if you’ve noticed an issue with your Alen air purifier, and you can fix it yourself.
