How long do Honeywell air purifiers last?

Assuming you have recently started researching air filters, chances are you are already sold on the idea, considering the significant difference they make in a space.

However, they do not come cheap. That’s why many people are always skeptical about whether or not the purchase will make sense in the long run. Should you go for the more expensive or cheaper ones?

Like most man-made equipment, Honeywell air filters have a limited life span. If the model you have comes with a HEPA filter, then its lifespan will be 4-5 years. On the other hand, if it only comes with a carbon filter, the life span decreases to 3-4 years.

Performing timely maintenance practices on your air purifier plays a huge role in its overall life span.

Signs that you need to change your air filter

One of the ways you can elongate the lifespan of your Honeywell air purifier is by changing the filter according to the manufacturer’s recommendations. These are some of the signs that you need to change the air filter:

1. If you cannot remember the last time you changed it

True HEPA and activated carbon filters are made to serve you for an average of 8,760 hours. In most cases, this translates to anything from 6 to 12 months.

After that, you should only change them at least ten times before you need to replace your air purifier. Make sure to follow proper disposal recommendations if you decide to get a new air purifier.

2. Strange smells

If opening the windows whilst running your Honeywell air filter does not get rid of odor in the house, then it is a sign that you need and replace the air filter.

Do try and replace the filters inside the air purifier beforehand. This air filter disposal guide should guide you to get rid of the filters properly.

3. The appliance starts overheating

When your air purifier starts over-heating, it is overworking to perform its most mundane task. Therefore, you need to replace it before it stops working completely.

Note that in this case, you could also be exposing your family to a health danger when running an air purifier with dirty filters.

4. Dusty surfaces

The moment you notice that the surfaces are dusty, then that means that the air filter isn’t efficient and should be replaced.

If you have already replaced the filter as per routine, then chances are you need to replace the air purifier as a whole because some parts are not working as they should

5. You are having allergic reactions

If your allergic reactions ceased after getting the purifier but seem to have returned then you need to change the air filter.

If you’ve installed a new filter but the situation hasn’t changed then you need a new air purifier. You can check out our list of the best air purifiers for allergies.

Factors that affect the longevity of an air filter

The lifespan of an air filter differs according to different factors. Understanding these factors is the key to improving the life span of the filter and also making an informed decision on when you need to change it.

1. The size of your room

The size of the space the air purifier is in determines how much work it will be doing on a usual basis.

The bigger the space, the more air there will be to clean. You will need to replace the air purifier more often and vice versa.

The function of the space also plays a part. For example, if you have placed the air purifier in your painting room, then it will need to be replaced more often than in you placed it in your bedroom due to the different impurities in the air of the two rooms.

2. The type of filter you have

All Honeywell purifier models are designed to work in the same fashion.

However, they are all fitted with different types and qualities of filters, motors, and hardware, which dictate the air purifier prices.

When you make the purchase, make sure to confirm the model’s life span you have got.


These are the most commonly asked questions about Honeywell air purifiers:

1. Do Honeywell air purifiers come with a warranty?

Yes, they do. All Honeywell purifiers come with a 5-year warranty if the device malfunctions or if the defect happened in transit.

Either way, you will need to fill out the warranty card within ten days of purchase to claim the service.

2. Should I open my windows when using the air purifier?

This depends on what you want the results to be.

For example, opening the windows will bring in a breeze of contaminated air but closing the windows will give the air purifier a chance to purify the air in the room.

Note that running an air purifier while keeping your windows open will overwork the air purifier.

3. Can an air purifier cause a fire?

Yes. Almost all electronic devices pose a fire hazard if not used accordingly or if there are problems with the power connections in the home. So be careful!


Honeywell air purifiers are very functional and worth the money. If maintained well, you can use the equipment for six years.

Make sure to look out for the signs above that indicate the purifier is due for an upgrade for the best results.
