If your device doesn't have in-build indicators, these scenarios will help you determine if your air purifier needs filter replacement. 

To ensure your air purifier always works at its best and keeps your air clean, you should acknowledge how often to change the air purifier filter. Read on to learn about a range of air scrubber filters and discover how frequently you need their replacement!

 

How Frequently Does Your Air Purifier Require Filter Replacement? 

 

Generally, it is recommended to change an air purifier filter once every year. But, it also depends on how frequently you run your home air scrubber and how much pollution you get in your indoor air, specifically when you’re living in highly-populated city areas because then you’ll need filter replacement more often. 

 

What Are The Signs Indicating The Need For Air Filter Replacement? 

 

You may need to realize when it's the right time to replace your air scrubber filters. That's why most of our commercial air scrubbers, such as the Drieaz air scrubber, feature an in-built filter replacement indicator that lets you know whenever your filter gets dirty or needs to be replaced. You may also consider the following signs to find out that the time has come that your air purifier needs filter replacement: 

• You may notice your air purifier making unusual sounds
• The allergic or asthmatic patients have breathing difficulties worsening
• You may notice more dust or pat dander all around 
• You may feel musty or moldy odors in your indoor air 
• The device is losing its airflow efficiency
• The filter may look gray or black or filled with excessive dust

 

 

Why Do Air Purifiers Need Frequent Filter Replacement? 

 

Air purifier demand has significantly risen within the past few years, specifically after the COVID-19 pandemic. It is because most people have switched to remote work, and that's why their time spent indoors has greatly increased, which requires frequent improvement in air quality. 

As per the research by the U.S. Environmental Protection Agency, the concentration of pollutants due to multiple factors in indoor air makes it two to five times more harmful than outdoors. Every filter has a variable lifespan depending on its type, technology, and usage. Permanent filters only require regular cleaning to remove trapped particles and don't need replacement. 

Some air purifiers use carbon technology to eliminate household odors and small particles from the air, which usually require replacement every 3-6 months if used frequently. Pre-filters require regular cleaning at least once a month and need to be replaced every three months or when the condition of the filter worsens.

Filtration technology that uses HEPA Filters is efficient in trapping the tiniest particles in the air, as small as 0.3 microns, and captures up to 99.97% of allergens. Replaceable HEPA filters usually require 6-12 months for filter replacement, but this can significantly vary depending on environmental and usage factors. You can check out our 2000 cfm air scrubber and job site air scrubber, as these are equipped with HEPA filters to improve the air quality to the top level.    

Many factors can indicate filter replacement more often, earlier than recommended by the manufacturer. These could be: 

• You may have many pets at home which keep shedding a lot throughout the year. 
• You’re using your air purifier for more than 12 hours a day. 
• There is an excessive use of wood-burning stoves at your home that keeps on producing smoke and bad odors.
• If you're residing in densely populated areas or surrounded by wildfires where extremely polluted outdoor air enters the home frequently.
• You are unable to perform regular deep cleaning or vacuuming of your home (should be at least once a well), which traps excessive dust and molds on hidden areas. 

 

 

Benefits Of Regular Air Purifier Replacement 

 

Now, you must know the importance of regular air scrubber maintenance and filter replacement. However, you can enjoy the following benefits by cleaning and replacing their filters regularly:   

Experience the Fresh Indoor Air Quality

Replacing an air filter on a regular basis offers multiple benefits, which also include experiencing the fresh air at your home or office. A filter helps to capture airborne particles, including dust, molds, dander, bacteria, bad odors, and allergens from your surroundings that may affect your immune system or can cause allergies and exacerbate symptoms of asthma. Changing the filter regularly ensures that these harmful particles can easily be trapped in the air purifier and makes sure that you can breathe easily.

The Air Purifier Will Work Professionally

Frequent replacement of an air purifier filter can make them work correctly or with more efficiency. Over time, you need to clean or change your filter when it is required in order to avoid severe damage, leading to more maintenance costs and bad air quality. So, if you want your air purifier to work professionally and efficiently, keep an eye on filter replacement indicators or signs to take immediate action. 

 

Less Dust Cleaning Hectics

Whenever you think of buying an air purifier, its main purpose is to clean your surroundings and make the indoor air fresh. Dust particles are extremely lightweight and float around the area of your home that your air purifier filter traps inside. These dust particles start to wear off the filters and turn them gray. So, if you keep replacing your air purifier filter regularly, you have to spend less time cleaning its surface while enjoying completely purified air quality.
