Air purification method


The Shark NeverChange Max air purifier effectively cleans indoor air from common pollutants such as dust, animal hair, and pollen. This Shark air purifier is the first brand to use the NeverChange HEPA filter, designed for a 5-year lifespan.

Design and Features

The purifier boasts a simple and modern exterior design with predominantly white color. The front of the machine features an LED display indicating air quality, control buttons, and air quality sensors. Meanwhile, the back of the machine includes connection ports, heat dissipation vents, and exhaust holes.

Exterior Design

    • LED Air Quality Display: The LED screen displays room air quality in 4 levels: Good, Fair, Average, Poor.
    • Control Buttons: Control buttons include the power button, fan speed adjustment button, timer button, and sleep mode button.
    • Air Quality Sensors: Air quality sensors help the machine automatically adjust fan speed based on room air quality.

    • Pre-filter: Removes larger particles like dust, hair, pollen, with a size greater than 2.5 micrometers.
    • HEPA Filter: Removes 99.98% of dust particles, bacteria, viruses, with a size smaller than 0.3 micrometers.
    • Activated Carbon Filter: Eliminates odors and harmful gases.

Shark produces some of the most reliable vacuum cleaners and is a member of the same company as Ninja, a well-known kitchen appliance manufacturer. Thanks to SharkNinja's positive reputation, it's not surprising that the NeverChange Air Purifier comes with many useful features. The sleek and clean design of the portable purifier provides a high-tech feel and the ability to monitor air quality.

The air purifier not only uses a HEPA filter that exceeds standards but also includes two external filters to capture larger particles and pet hair, preventing early clogging of the HEPA filter. Cleaning the external filters with a vacuum cleaner takes approximately 30 seconds for each side.

One of the most useful features is the automatic mode. When in automatic mode, the air purifier will turn off the fan when the air quality reaches 100% for at least five minutes. It will automatically restart when the air needs to be cleaned again. This not only saves energy but also prolongs the life of the HEPA filter.

The Odor Elimination Technology box included significantly reduces mold odors during basement cleaning and works effectively in controlling kitchen odors. The air purifier's customizable options with three dimming levels (one being a night mode without emitting light) and the ability to mute the air purifier so that buttons do not emit beeping sounds have all received high praise.

Installation and Performance

To unbox and set up the Shark NeverChange HP302 air purifier, you need to follow these steps:

  • Open the box and take out the components inside, including the air purifier, main filter, activated carbon filter, pre-filter, power cord, and user manual.

  • Install the main filter, activated carbon filter, and pre-filter into the air purifier.

  • Plug the air purifier's plug into an electrical outlet.

  • Adjust the settings of the air purifier using the control buttons on the machine.

  • Start using the air purifier.


  • Do not use the air purifier in places with temperatures exceeding 40°C or below 0°C.

  • Avoid using the air purifier in highly humid rooms.

  • Do not use the air purifier in areas with harmful chemicals.

  • Regularly clean the filters to ensure the air purification efficiency of the machine.

I have tested the Shark NeverChange Max air purifier for two weeks and used it in three different environments.

I placed it in the living room, the central area of my house, connected to the kitchen, dining room, bedroom, and bathroom - totaling about 900 square meters. The air purifier took a few seconds to adjust the indoor air quality in my home, resulting in 95% air quality. This rate increased to 100% within a few minutes.

As someone sensitive to odors, I wasn't too excited about the included Odor Elimination Technology box with its strong scent. I was even considering not installing it, but I wanted to accurately test the air purifier, so I set it to the lowest fragrance option (or turned it off, which is also an option). Surprisingly, the scent was very mild and genuinely pleasant. After two weeks, I still vaguely noticed it when coming home and didn't pay much attention to it.

I also brought it down to the basement while sorting seasonal clothing. I was highly impressed by the almost immediate response rate in air quality when I opened the laundry bin.

Finally, I took it to a cabin in a national forest for a weekend getaway, where the air quality dropped to 70% when the neighboring cabin lit a campfire in the evening. After I closed the cabin windows, the Shark air purifier cleaned the smoky air and restored the air quality to 100% within 10 minutes.
