Air purifiers have gained popularity as we become more aware of air quality and its impact on our health, particularly for allergy sufferers and pet owners.
As someone with asthma and various allergies, I've found that a quality air purifier can significantly enhance my home environment. I notice improvements in my breathing and overall well-being when the air is clean.
The NeverChange MAX stands out among Shark's offerings, boasting coverage of up to 1,400 square feet, with filters designed to last up to five years without replacement. There's also a budget-friendly variant, the Shark NeverChange, which covers 650 square feet. Let's explore the performance of the Shark NeverChange Air Purifier MAX.
Shark NeverChange Air Purifier MAX: Pricing
This air purifier is priced around $329.99 at Shark, Amazon, Lowe's, and Best Buy.
Air purifiers generally range from $100 to over $600. While they all serve a similar function, pricier models usually cover larger areas or offer better particle filtration.
The NeverChange MAX's coverage of 1,400 square feet and washable prefilters make it a fantastic deal, considering the savings on filter replacements.

Shark NeverChange Air Purifier MAX: Setup

Unboxing process.
It arrives in a large cardboard box with the air purifier inside. Setup is straightforward: remove the HEPA filter from the plastic by twisting the bottom panel and peel off the warning sticker from the touchscreen.
An optional anti-odor cartridge comes in a canister, which you can insert into the top slot of the purifier. It features a dial for adjusting the level of scented air.
Just plug it in and switch it on, and it will start purifying the air right away, taking a moment to assess the air quality before displaying it on the screen.

Shark NeverChange Air Purifier MAX: Design & Features

The Shark NeverChange Air Purifier MAX is 22.5 inches tall.
This model's standout feature is its cleanable filters, known as Debris Defence filters. They can be removed, washed, and reused, allowing the HEPA filter to last up to five years, hence the name 'NeverChange.'
While not a new concept, the NeverChange enhances this by making filters washable, ensuring the HEPA filter maintains effective allergen capture without needing replacement for an extended period.

The removable filters are easy to clean.
Like other Shark models, the NeverChange MAX features Clean Sense IQ technology, which continuously monitors air quality while purifying. Air quality information is displayed as a percentage, and in auto mode, it adjusts power based on air needs.
It tracks PM1, PM2.5, and PM10 particle values, essential for effective air purification. Understanding these sizes helps assess the types of particles prevalent in your environment:
- PM1 particles are smaller than 1 micron, including fine allergens and viruses.
- PM2.5 particles encompass smoke from natural and man-made sources.
- PM10 particles include larger debris like dust and pollen.

The NeverChange MAX features a touch control panel.
The air purifier is controlled via a touchscreen on top, allowing you to select auto mode, fan speed, and toggle between air quality and particle information. You can also set a timer for up to 12 hours, check filter cleanliness, and adjust brightness.
The front display shows air quality, individual particle counts, or timer settings, with a color-coded ring indicating air quality: red for poor (0-69%), orange for fair (70-84%), and green for good (85-100%).

Notably, the NeverChange MAX is 22.5 inches tall, making it unsuitable for small surfaces like coffee tables. Its size corresponds to its expansive coverage and is light enough for easy relocation throughout the house.
Constructed primarily from plastic, it remains lightweight but may not appeal to those preferring metal designs. Fortunately, its matte white finish allows it to blend seamlessly into various decor styles.
Shark NeverChange Air Purifier MAX: Performance
Overall, the NeverChange MAX excels at maintaining clean air. In my experience living in a shared house, I tested it across multiple rooms to gauge its efficacy.
It rapidly improved air quality, going from 60% to 100% in about 30 minutes with proper airflow. I found its responsiveness impressive; after cooking, it quickly indicated a drop in air quality, which it restored efficiently.
Setting it to auto mode simplifies usage, optimizing energy consumption while enhancing air quality. This smart feature likely contributes to energy savings.

Ideal for open-plan areas and apartments, the unit performs best in less segmented homes. I also appreciated its quiet operation; settings 1 to 3 produce noise comparable to a quiet fan, while levels 4 and 5 are louder but rarely necessary.
The anti-odor cartridge works effectively, though the scent can be overwhelming with prolonged use. It's reminiscent of a car air freshener—pleasant at times, but easily adjustable via the control dial.
Shark has clearly put thought into the user experience. Controls are intuitive, offering three brightness settings and the option to display air quality or particle values. This feature enhances understanding of the air quality, especially during everyday activities.
Shark NeverChange Air Purifier MAX: Maintenance
Maintaining the filters is straightforward; simply slide them out and clean them with minimal effort. They are lightweight and small enough to rinse under water easily.
Although I've only had the purifier for a few weeks, its longevity claim of a 5-year HEPA filter is ambitious. However, the washable Debris Defence filters seem effective in keeping the internal components clean.

The Debris Defence filters are compact and easy to maintain.
Shark NeverChange Air Purifier MAX: Final Thoughts
Like many of Shark's products, the NeverChange Air Purifier MAX prioritizes user convenience. It accurately detects and adjusts air quality, optimizing energy use while maintaining cleanliness. Users can track particle levels, gaining insights into how various activities impact air quality.
At its price point, it's competitively affordable. For comparison, the Molekule Air Pro covers up to 1,000 square feet and comes with similar detection features but costs around $1,000. The NeverChange MAX's larger coverage and lower price make it a smart economic choice.
While there are visually appealing air purifiers available, the NeverChange MAX's performance, user-friendliness, and value make it a solid contender among the top air purifiers.
How Does the Shark NeverChange Air Purifier MAX Stack Up?
The primary advantage of the NeverChange is its long-lasting filters, which significantly reduce replacement costs. Priced competitively against other units, it offers affordability without compromising quality.
Nevertheless, other air purifiers have distinct advantages. The Molekule Air Pro employs unique technology to destroy pollutants at the molecular level, making it FDA-approved as a Class II medical device. However, this technology comes with a higher price tag, at $1,015 for the Air Pro and $340 for the smaller Air Mini+.
Additionally, consider multifunctional purifiers like the Shark Air Purifier 3-in-1, which provides heating, cooling, and air purification, or the Dyson Purifier Humidify & Cool Formaldehyde, which manages humidity and eliminates formaldehyde.
Air purifiers significantly enhance indoor air quality by trapping allergens and harmful particles. For optimal results, complement your purifier with one of the best dehumidifiers.
