What is a HEPA Filter?
A HEPA filter is a type of air filter that can capture particles as small as 0.1 micron, making it extremely effective at removing allergens, viruses, bacteria, and other pollutants from the air.
These filters can remove over 99.9% of particles from the air stream, which is a game-changer for people with allergies or respiratory problems.
HEPA filters are designed to catch the smallest dust particles, with an efficiency of up to 99.999%, making them one of the most effective air treatment technologies available.
The smallest and most penetrating particle size (MPPS) is what makes HEPA filters so effective, and they are particularly good at catching particles larger than one micron, which are often associated with fine dust and allergens.
By using a HEPA filter in your home or bedroom, you can significantly improve the air quality and make a big difference in your health and well-being.

How They Work
Winix air purifiers have a 4-stage filtration system that effectively cleans indoor air. The quality of the HEPA filter used by these air purifiers is key to their effectiveness.
The HEPA filter is composed of a mesh of randomly placed fibers. These fibers are arranged in an accordion shape, which gives them a greater capacity to capture particles.
This unique arrangement of fibers allows the HEPA filter to capture a wide range of particles, including dust, pollen, and other airborne pollutants.

Air Purifier Technology
The WINIX Air Purifier's PlasmaWave Technology reduces static electricity, capturing air pollutants in its 4-stage filtration system. This technology is especially effective in reducing VOCs and odors from cooking, pets, and smoke.
The True HEPA Filter in WINIX air purifiers captures 99.99% of airborne allergens, including pollen, dust, smoke, pet dander, and ultrafine particles as small as 0.003 microns. This filter efficiency is very close to 100%.
Independent laboratory tests have shown that WINIX air purifiers can provide advanced air quality, even against the smallest inanimate particles.

Air Purifier Types
There are several types of air purifiers available, including HEPA filters, which can capture 99.97% of particles as small as 0.3 microns.
Activated carbon filters are another type, which can absorb gases, odors, and chemicals.
Some air purifiers use UV light to kill bacteria and viruses, and can be especially useful in areas with poor air quality.
Ionizers release negative ions that attract and trap pollutants, but can also create ozone and may not be suitable for people with respiratory issues.
Whole-house air purifiers are designed to clean the air in an entire home, and can be installed in ductwork or as a central unit.
Advanced 3-Stage Filtration with Plasma Technology

Air purifiers with PlasmaWave Technology, like the Winix model, can significantly improve indoor air quality by reducing static electricity. This allows air pollutants to be captured by the airflow and directed into the air purifier's filtration system.
The Winix Air Purifier uses a 4-stage filtration system, which is a key feature of its design. True HEPA filters are a crucial part of this system, capturing 99.99% of airborne allergens, including pollen, dust, and pet dander.
The PlasmaWave Technology in Winix air purifiers also helps to reduce VOCs and odors from cooking, pets, and smoke. This is especially useful for households with pets or smokers.
Independent laboratory tests have shown that Winix air purifiers can capture particles as small as 0.003 microns in size. This level of precision is essential for removing ultrafine particles from the air.
Winix True HEPA filters can capture particles as small as 0.003 microns, making them highly effective at removing airborne allergens.

Air Purifier Filters
Our air purifiers have a 3-stage filtration system, including a True HEPA filter that captures 99.99% of airborne allergens as small as 0.003 microns. This is thanks to the advanced filtration technology used in our products.
One of the key features of our air purifiers is the PlasmaWave Technology, which reduces VOCs and odors from cooking, pets, and smoke. This technology also helps prolong the lifespan of the True HEPA filter.
The True HEPA filter is designed to capture 99.99% of airborne allergens, including pollen, dust, smoke, pet dander, and other ultrafine particles. This makes it an essential component of our air purification system.
It's essential to replace the filters regularly to maintain the effectiveness of the air purifier. A filter that is contaminated and past its lifespan will be filled with contaminants, and air cannot pass through the filters and be properly cleaned.
Here's a quick guide to the replacement schedule for our air purifier filters:
By following this replacement schedule, you can ensure that your air purifier continues to provide clean and fresh air for you and your family.
Air Quality Indicators

Winix air filters have a feature that measures and adjusts the fan speed in real-time based on air quality.
The built-in air quality sensors in Winix air filters are designed to capture 99.99%* of airborne allergens including pollen, dust, smoke, pet dander, and other ultrafine particles as small as 0.003 microns.
Independent laboratory tests have shown that Winix air filters can reduce VOCs and odors from cooking, pets, and smoke, helping to prolong the True HEPA Filter lifespan.
Winix air filters use Advanced 3-Stage Filtration with PlasmaWave Technology to improve indoor air quality and reduce static electricity, which allows air pollutants to be captured by the airflow.
The LED light on Winix air filters changes in real-time based on air quality, providing an instant visual indicator of the air quality.
Winix air filters can capture inanimate particles as small as 0.003 microns in size, as proven by independent laboratory tests.
Maintenance and Replacement
Replacing your Winix filter is a straightforward process, especially with the Filter Change Indicator that illuminates when it's time for a change.

Proper maintenance of your air purifier begins with the unit's filtration system, which means replacing the filters when needed.
There are multiple filters within an air purifier, each requiring a different replacement schedule. The generalized lifespan of filter types is as follows: Pre-Filters must be cleaned every 14 days, True HEPA Filters every 12 months, Activated Carbon Filters every 3 months, Coated DeOdorization (CD) Carbon Filter every 12 months, and Winix Washable AOC Carbon Filter every 12 months and washed every 3-4 months.
Regularly checking your air purifier's filters is crucial to ensure they're not contaminated and past their lifespan. A filter that's filled with contaminants like odor, allergens, dust, pet dander, and smoke will not allow air to pass through and be properly cleaned, reintroducing contaminants into your environment.
Here's a quick reference guide to keep track of your Winix filter replacement schedule:
By following this guide and replacing your filters on time, you can ensure your air purifier is working at its best to improve your air quality.
Frequently Asked Questions
Can you leave a Winix air purifier on all the time?
Yes, you can leave a Winix air purifier on continuously (24/7) for maximum efficiency, as the running costs are negligible. This approach provides the best air cleaning results, but there are other factors to consider when deciding on usage.
Can I wash my WINIX air purifier filter?
No, do not wash the WINIX air purifier filter. It must be replaced every 3 months as the pref and carbon filters will separate.
What is the difference between WINIX 116130 and 116131?
The main difference between WINIX 116130 and 116131 is the type of media used in the 116131 filter, which is made of a different material. Both models are 99.97% True HEPA filters, but the 116130 is slightly cheaper.
