Shark NeverChange Review: Is the 5-Year Filter Claim True?

Full Review

Shark has made a significant impact on the air purifier market with its NeverChange series, primarily because the idea that the filters on this device “never” need to be replaced.

But how true is that? How long-lasting is the filter on the Shark NeverChange, and can it really last as long as Shark claims?

We tested the Shark NeverChange air purifier’s performance, odor neutralization, noise levels, and power consumption. Additionally, we performed a thorough analysis of all its specifications to determine whether it’s worth buying.

In this article, I’ll also compare the Shark NeverChange with some similar devices in its category, so I highly recommend reading on to learn more about this device.

How We Tested the Shark NeverChange HP152?

1. For the filter efficiency testing, we used the Temtop LKC-1000S laser particle meter, which measures PM2.5 (µg/m3), PM10 (µg/m3), Particles (per/L), and HCHO (mg/m3) in the air, and also calculates the AQI.

2. We placed the Shark NeverChange HP152 in two separate performance tests, one in a 194 sq. ft. (18 m²) room and the other in a 320 sq. ft. (30 m²) room. Then, we recorded the initial air quality values using the Temtop laser particle meter and let the Shark NeverChange HP152 run at maximum speed.

3. After 60 minutes, we measured the new values using the Temtop laser particle meter and saved the data.

4. Next, we placed the Shark NeverChange HP152 in a glass box, which we then filled with smoke. Then, we measured how much time was needed for the air purifier to remove all the smoke from the box.

5. Using a special noise measurement tool, we tested the air purifier’s noise level at all speeds. We measured the noise level on the dBA scale.

6. Finally, we measured the power usage at all speeds using an energy meter, after which we calculated how much it would cost to use the device at a particular fan speed for one month. For reference, we used an energy price of $0.12 per kWh.

Although the Shark NeverChange isn’t a small air purifier, it doesn’t boast an impressive airflow.

It has a CADR of just 97 CFM (165 m³/h), making it ideal for rooms up to 150 sq. ft. (14 m²). In a room of this size, it will clean the air 4.8 times per hour.

However, since the Shark NeverChange demonstrated much higher performance and potential, we tested it in two rooms larger than the recommended size.

In addition to these tests, I used the Shark air purifier in my living room for a while, and I have to say I’m quite satisfied with its performance. It also does a great job neutralizing bad odors.

Testing in a 194 sq. ft. (18 m²) Room

In the first test, performed in a 194 sq. ft. (18 m²) room, we measured how much the Shark NeverChange could improve air quality after 60 minutes of running at maximum speed.

This air purifier improved air quality by an impressive 92%, reducing PM2.5 particulate matter from 105.5 to 7.9 µg/m³.

Compared to the competition, Shark ranks very well. As you can see on the chart, it’s positioned somewhere in the middle.

For example, the Levoit Core 300S, which is one of Shark’s biggest competitors, achieved a slightly better result in this test, improving air quality by 94% under identical conditions.

Overall, the Shark NeverChange delivered fantastic results in this test.

Testing in a 320 sq. ft. (30 m²) Room

In the second test, we placed the Shark NeverChange in a 320 sq. ft. (30 m²) room and let it run at maximum speed.

In just 60 minutes, it managed to improve the air quality by an impressive 90%.

This is an outstanding result as well, especially considering that the room is more than twice the size of the recommended.

The Shark NeverChange has five fan speeds and an auto mode. It’s relatively well-optimized for noise, which is expected given its CADR.

At the lowest speed, it produces 40.4 dBA of sound, placing it among the quietest air purifiers at the lowest setting that we’ve tested.

For comparison, the Coway Airmega 100, which has a similar CADR to the Shark, produces about 40.3 dBA at its lowest speed, while the Philips 800 Series produces 41.8 dBA.

At maximum speed, it’s also well-optimized, though I expected slightly better noise control. It produces 62.4 dBA at the highest setting.

One feature I’d like to see is a dedicated sleep mode that further reduces noise levels and dims all the device’s indicators with a single click. Even better would be an auto sleep mode, similar to the one found on the Winix C535 air purifier.

Overall, the Shark NeverChange is a well-optimized air purifier that operates quietly enough for everyday use.

Another feature I like about the Shark NeverChange is its well-optimized 26W motor.

While there are air purifiers in this class with better power-to-CADR ratios, I must say Shark did an excellent job with this device. It consumes only 25.5W at maximum speed.

This means that if you run the Shark NeverChange at maximum speed, 24 hours a day for a month, your electricity bill would increase by about $2.24, which is very low.

For comparison, the much larger GermGuardian AC4825 will cost significantly more to operate without delivering better performance or a much higher CADR. Under the same conditions, it would cost you about $3.78. Please refer to the chart for more comparisons.

In addition to electricity costs, there’s also the expense of replacement filters. According to Shark, the filter should be replaced every five years. However, I’m skeptical about this claim. I’ve never seen such a small HEPA filter last more than 1-2 years. The only air purifier we’ve tested that recommends a five-year filter replacement is the Austin Air HealthMate Jr.

Realistically, I believe you’ll need to replace the filter every 1-2 years, depending on your environment and how frequently you use the air purifier.

Overall, the Shark NeverChange is easy and affordable to maintain, especially if the filter truly lasts up to five years.

Filtration Technology

The Shark NeverChange uses four-stage filtration technology consisting of a pre-filter, pet particle filter, activated carbon, and NanoSeal HEPA.

The cylindrical filter is located inside the device, in the lower half. The filter is of exceptional quality, as proven in our performance tests.

As I’ve mentioned several times in this review, I’m not sure that the Shark NeverChange HP152 filter can truly last five years, especially with regular use. I believe it will likely need to be replaced annually or, at best, every other year.

Additionally, this filter doesn’t appear visually different from the filters in other Shark HP100 series air purifiers, which typically require replacement about once a year.

Pre-filter (Debris Defense)

The first stage of filtration is the pre-filter. Essentially, the Shark NeverChange has two pre-filters positioned on the sides of the device.

This filter is permanent and washable, and its main purpose is to capture large dust particles, hair, pet hair, lint, and similar particles, thereby extending the lifespan of the other filters.

You should know that this filter needs to be cleaned regularly, I recommend at least twice a month.

However, while the pre-filter is washable, the cylindrical HEPA filter isn’t.

Pet Particle Filter

This thin layer serves as the second stage of filtration and is attached to the activated carbon filter.

It closely resembles the pre-filters found in some similar air purifiers. The primary purpose of this filter is to collect pet dander. As recommended in the user manual, it should also be cleaned periodically.

Cleaning it twice a month, just like the pre-filter, is likely the best approach. You can clean it using a vacuum cleaner or a dry cloth.

Activated Carbon Filter

The third layer of filtration is the activated carbon filter, which is primarily responsible for neutralizing unpleasant odors.

It effectively tackles smells from cooking, pets, and various gases.

NanoSeal HEPA Filter

The final and most important stage of filtration is the HEPA filter. It captures small airborne particles such as pollen, dust, smoke, allergens, and similar pollutants.

This filter removes 99.98% of large, small, and microscopic particles (based on EST-RP-CC007.3, 0.1–0.2 microns).

Essentially, the NanoSeal HEPA filter is the key contributor to the performance of this air purifier.

How to Replace the Shark NeverChange Air Purifier Filter?

The Shark NeverChange requires filter replacement, but the key selling point of this model is that the filter lasts up to five years, which is up to 20 times longer than some competing air purifiers.

Interestingly, I haven’t been able to find replacement filters specifically for the Shark NeverChange, which is somewhat understandable since this is a new model on the market. And if the filters truly last that long, it makes sense that replacement filters wouldn’t be readily available in the first year after the device’s release.

However, I did notice that filters from the Shark HP102 model are compatible with the Shark NeverChange HP152 air purifier.

The Shark NeverChange has a filter reset indicator that alerts you when it’s time to clean the pre-filter or replace the HEPA filter. If the display shows “Check Dust Filters,” you need to clean the pre-filter. If it shows “HEPA Status,” it’s time to replace the HEPA filter.

The replacement procedure is simple and consists of just a few steps.

Odor Neutralizer Technology

Odor Neutralizer is a technology that Shark claims can improve odor reduction by up to 2x.

However, I can’t say that this technology completely eliminates unpleasant smells, but I can definitely say that the scent in the room where I use the odor neutralizer is much nicer and feels noticeably fresher.

That said, it’s important to note that this scent may not appeal to everyone, as preferences vary.

The odor neutralizer is located on the top of the device, right next to the control panel.

You can adjust it by turning it clockwise or counterclockwise, depending on how quickly you want to use up the cartridge.

Setup and Installation

Like most air purifiers I’ve used, the Shark NeverChange doesn’t require any special preparation beyond basic filter preparation.

Although the filter comes pre-installed in the device, you’ll need to pull it out, remove it from its protective packaging and place it back into the purifier.

Next, unpack the odor neutralizer and insert it into the designated slot located on top of the device.

Once these steps are completed, your air purifier is ready for use. All that’s left is to place it in your desired location and turn it on.

But please, make sure not to block the airflow of the device while placing it.

Design

The Shark NeverChange is a modern air purifier with a unique design and excellent build quality, making it easy to blend into almost any environment.

At first glance, this model reminded me of the Shark HP102, which I tested some time ago. They have similar design, filter type, filter size, and overall dimensions. The key difference is that the Shark NeverChange features side attachments where the pre-filters are located.

One thing this Shark model lacks is a carrying handle. However, to be fair, the air purifier isn’t very heavy, so moving it from room to room shouldn’t be too difficult.

The model I purchased for testing is charcoal black with a matte plastic finish. However, there are also larger models of this air purfieir that are avaliable in white and black.

Display and Controls

All the controls are located on the control panel, which is positioned on the top of the device.

This panel has LED indicators and touch buttons. Additionally, there’s a display on the front of the device that provides extra information, such as air quality data, the air quality indicator light, and the timer.

The touch buttons are precise, responsive, and easy to use. However, I would have preferred if this air purifier were compatible with a smart app, which would make controlling it even more convenient.

Interestingly, you can purchase a remote control separately as an accessory, allowing you to operate the device from a distance.

Airflow

Although it has a cylindrical shape, the Shark NeverChange draws in air through openings on the sides.

Honestly, I’m not a fan of this air intake method on cylindrical air purifiers, as it gives the impression that the filter may not wear out evenly. For this reason, I recommend rotating the filter from time to time.

The filtered air is released through vents located on the top of the device.

Size and Dimensions

The Shark NeverChange HP152 has dimensions of 10.5 x 9.3 x 14.9 inches (26.7 x 23.6 x 37.8 cm) and weighs 7.25 lb (3.28 kg).

Although it’s a relatively lightweight air purifier, the addition of a carrying handle would be a perfect fit.

What’s in the box?

When you buy the Shark NeverChange HP152 air purfieir you will get 1x air purifier, 1x NeverChage HEPA filter, Shark odor neutralizer assembly and catridge, and user manual.

Features Overview

Frankly, I can’t believe that this air purifier doesn’t have smart features, as I think that would boost the device to a much higher level. In this price range, I would expect smart functionality.

However, the Shark NeverChange does offer some exceptional advanced features, which I will describe below.

Air Quality Sensor & Indicator

Shark uses Clean Sense IQ™ technology to measure indoor air quality. The sensor is located on the back of the device and measures PM particles in real-time, specifically PM1, PM2.5, and PM10.

It’s important to note that this sensor doesn’t measure VOCs. Why is this important? Because if your primary goal is to keep the device in auto mode in an environment polluted with VOC particles, the auto mode likely won’t function properly.

Another interesting point is that this sensor works in combination with the air quality indicator and auto mode features. The air quality indicator is an LED ring located around the display on the front of the device, which lights up in different colors depending on the current air quality.

Additionally, the display shows the current air quality as a percentage. The higher the percentage, the better the air quality. Check the table below for detailed percentage ranges.

Air Quality	Air Quality Percentage	LED Indicator Color
Poor	0%–69%	Red
Fair	70%–84%	Amber
Good	85%–100%	Blue

By pressing the air info button on the display, you can switch how air quality data is shown, focusing on PM1, PM2.5, or PM10 particle levels.

I’d also like to point out that the sensor continues to operate and read air quality data even when the air purifier is turned off, which is why this device consumes 0.3W in standby mode.

Auto Mode

Auto mode is another feature that works in combination with the air quality sensor.

When in auto mode, the device adjusts the fan speed based on the current air quality. This means that if the air quality in your room is poor, the device will switch to a higher fan speed, and vice versa.

An interesting aspect of auto mode is the Shark NeverChange’s built-in eco mode. When the air quality reaches 100% and remains excellent for more than five minutes, the device will automatically switch to eco mode. This feature further optimizes filter usage while maintaining excellent air quality in your home.

I’ve seen a similar feature in the Coway AP-1512HH, which has a dedicated ECO mode functionality.

Overall, auto mode is a highly useful feature if you want to automate your Shark air purifier for hassle-free operation.

Remote Control

The remote control is an excellent addition to this device, but it isn’t included with the Shark air purifier and must be purchased separately.

I consider it a major drawback that, for a device in this price range, you have to pay extra for a remote control.

With the remote, you can adjust almost all the functions of your device.

Brightness

This feature allows you to adjust the brightness of the display, LED indicator, and touch buttons.

Each press of the button cycles through three options: full brightness, partial dim, and fully dim.

When set to fully dim mode, all indicators on the device, including the air quality indicator, will be completely turned off.

Child Lock

This feature allows you to lock the control panel.

Press and hold for two seconds to lock the top control panel buttons. To unlock, press and hold for two seconds again.

Warranty

In general, Shark offers a one-year warranty for this air purifier, but most retailers provide a two-year warranty, which is why I would consider it to come with a two-year warranty.

Additionally, some retailers offer a three-year warranty for this model, so be sure to research your options before making a purchase.
