Shark HP102 Air Purifier – Tested & Reviewed

Full Review

Shark has been making a powerful impact in the air purifier market for some time now, offering a range of innovative, high-quality devices. In this review, I’ll take a close look at the Shark HP102 air purifier.

Interestingly, this is the first Shark product I’ve tested, which adds an extra layer of excitement to the review.

The Shark HP102 features a three-stage filtration system and, importantly, does not include an ionizer. It’s CARB-certified, meaning it’s completely safe to use.

The device also comes with several advanced features, such as an air quality sensor, air quality indicator, and auto mode. However, it lacks smart app connectivity, which I consider a slight drawback.

Overall, the Shark HP102 is a fantastic air purifier with excellent performance and a well-rounded feature set. I believe it’s highly competitive in its category—something that will become even more evident in the upcoming comparisons I’ll publish after this review.

How We Tested the Shark HP102?

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 HP102 in two separate performance tests, one in a 120 sq. ft. (11 m²) room and the other in a 194 sq. ft. (18 m²) room. Then, we recorded the initial air quality values using the Temtop laser particle meter and let the Shark HP102 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 HP102 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.

The Shark HP102 is a compact air purifier designed for rooms up to 124 sq. ft. (11.5 m²). The manufacturer suggests it can be used in slightly larger rooms, but based on my experience, I wouldn’t recommend pushing it beyond the stated limit.

To evaluate its performance, I tested the HP102 in two rooms that were approximately within its recommended coverage. As always, I used the Temtop laser particle meter to measure results.

In addition to standard room tests, I also ran the purifier in everyday conditions over an extended period, as well as in specific scenarios with high VOC levels and similar pollutants.

In both cases, the HP102 performed well, demonstrating the effectiveness of its filters.

Testing in a 120 sq. ft. (11 m²) Room

In the first test, performed in a 120 sq. ft. room, which is almost exactly within the recommended coverage, the Shark HP102 ran at maximum speed for 60 minutes. During that time, it improved air quality by an impressive 94%.

This result exceeded my expectations and confirmed that the Shark HP102 is a well-designed, highly competitive air purifier.

As shown in the chart, the HP102 achieved the best ranking among all the devices I put on the chart. For comparison, the Levoit Core Mini improved air quality by 91% under the same conditions, while the Morento MR2566 improved it by 82%.

As you can see, the Shark clearly leads in performance, while the Morento still ranks fairly well compared to other similar compact air purifiers.

Testing in a 194 sq. ft. (18 m²) Room

In the second test, performed in a 194 sq. ft. (18 m²) room, which is slightly larger than the recommended coverage, the Shark HP102 once again delivered impressive results.

In just 60 minutes of operation at maximum speed, it improved air quality by an outstanding 92%, reducing PM2.5 levels from 101.7 to just 8 µg/m³.

Taken together, these results show that Shark has achieved excellent performance in both tests, clearly demonstrating the strength of its filtration technology.

Performance – Smoke Removal Test

The Shark HP102 uses a relatively small filter, but it’s pellet-based, which is a key advantage for advanced odor neutralization.

To evaluate its performance, I placed the HP102 in a smoke box, filled the box with smoke, and measured how long it took to clear the air at maximum speed.

It needed just 29 seconds, which is an excellent result for a purifier with this CADR.

As shown in the chart, the Shark HP102 ranks around the middle of the group. For comparison, the Levoit Core Mini needed 74 seconds to remove the smoke, while the Levoit Vital 100S completed the same test in just 20 seconds.

The Shark HP102 has four fan speed settings, and for the noise test, I measured the sound level at each speed individually using a specialized dBA sound meter.

Interestingly, the HP102 is not particularly loud even at its maximum speed, though this is partly due to its lower airflow compared to some competitors. For example, the Levoit Core 300S produces 64.9 dBA at max speed—noticeably louder, but with higher airflow.

At its highest setting, the Shark HP102 produces just 56.5 dBA, while at the lowest speed it drops to an impressive 41.7 dBA. This makes it one of the quietest air purifiers I’ve tested and an excellent choice for bedrooms or other noise-sensitive spaces.

Overall, the Shark HP102 is a very quiet device with a well-optimized motor, making it barely noticeable during operation at most speeds.

The Shark HP102 is an energy-efficient air purifier thanks to its well-optimized 24W motor. At maximum speed, it draws no more than 20.5W.

To put this into perspective, if you ran the HP102 at full speed 24 hours a day for an entire month, your electricity bill would only increase by about $1.80.

And that’s the worst-case scenario; using auto mode or lower speeds (which is how most people run it) would reduce the cost even further.

For comparison, the Shark NeverChange HP152 would cost around $2.24 under the same conditions. You can see the full breakdown of consumption at each speed in the table below.

Of course, a smaller motor comes with trade-offs: for example, lower airflow, which is why the HP102 is best suited for rooms up to 124 sq. ft. (11.5 m²).

On top of electricity costs, you’ll also need to factor in replacement filters, which should be changed every 6–12 months depending on usage. To extend filter life, I recommend running the purifier in auto mode whenever possible.

While the HP102’s energy use is impressively low, I was genuinely surprised by the very high cost of replacement filters. This makes the device less cost-effective on a yearly basis compared to many of its competitors.

Setup and Installation

Like most air purifiers I’ve previously tested, the Shark HP102 requires some preparation before its first start.

To begin with, you need to unpack the device from the shipping box and then peel off all the protective tapes from it. Following this comes the most important part – preparing the filter. 

To make the filter ready: you have first to flip the air purifier upside down, remove the filter from the device, unpack it from the plastic wrap, and place it back into the device. By completing this step, your Shark air purifier is fully prepared and ready for use. 

Now, you can place the device in your desired location, plug it into a power source and turn it on.

Design

At first glance, this air purifier seems like a typical cylindrical device commonly seen among most small-to-medium-sized air purifiers. However, Shark has integrated some innovative features, high-quality materials, and details that make it more interesting than the typical air purifiers on the market.

The model I purchased for testing purposes is white, with black grilles on top and a black control panel and display, making it very appealing and eye catchy.

The Shark HP102 consists of two parts: the lower part, which features air intake vents and houses the filter, and the upper part, which contains the motor, air quality sensor, control panel, and fan grilles.

Regarding the design in general, I find it quite appealing. The device is very similar to competing devices in this category, but Shark added some details that add a touch of elegance. The build quality is excellent, as is the quality of the plastic. Everything is in place, the device is well assembled, and there are no irregularities such as rattling or deviations.

One potential drawback is the lack of a carry handle. However, given that this is a portable and lightweight device, I believe you will be okay with moving it from room to room.

All in all, this is a compact air purifier with an interesting design that I’m sure will fit into almost any home environment.

Controls and Indicators

The controls are placed on the top of the device. There you can find buttons, indicators, and a display.

The buttons you can find on the control panel are: power, air info, brightness, timer, filter life, child lock, fan speed, and auto mode button. They are touch sensitive, with a good level of sensitivity and a perfect layout that ensures you’ll encounter no issues during operation.

Moreover, the LED indicators are also easily readable, and overall, I’m absolutely pleased with how Shark has designed this control panel.

Airflow

The Shark HP102 is characterized by a cylindrical shape, and we can say that it consists of two parts. 

The lower part is where the air intake vents are located, which, unfortunately, are not 360-degree – the front/and some other parts are fully closed. The device draws in air through these vents, which is then filtered and exits through the grilles on the upper side. 

I have one piece of advice to remember, especially for first-time air purifier users. Please be careful when placing your air purifier and ensure you never block the air intake/outtake vents, as doing so could potentially damage the air purifier.

Size and Dimensions

With a weight of just 5.85 lbs (2,65 kg), the Shark HP102 air purifier is a light and portable device. Its dimensions are a compact 8.7 x 8.7 x 14.6 inches (22 x 22 x 37 cm). 

This is an incredibly lightweight and easy-to-move air purifier, although it lacks a carrying handle for effortless transportation.

What You Will Get in the Box

Inside the box of your newly purchased device, you’ll find: one Shark HP102 Air Purifier, a 3-in-1 Filter (pre-installed), and a User Manual.

Before starting the air purifier, you have to take a few important steps that I explained in detail at the beginning of the review. Jump to the Shark HP102 setup and installation guide.

Features Overview

The Shark HP102 is a smart air purifier equipped with plenty of advanced features. However, it lacks connectivity to a smart app, a feature that would raise this device to the next level.

Among this device’s unique options, I think the air quality sensor, air quality indicator, auto mode, and high-quality display are the most important ones.

Air Quality Sensor

The Shark HP102 Air Purifier has an air quality sensor that measures air quality in real time. This sensor uses Shark’s Clean Sense IQ technology. Every Shark model that uses Clean Sense IQ has this mark printed somewhere on itself, which is printed on the front in this case. 

A standout feature of the Shark air quality sensor is its ability to detect PM1, PM2.5, and PM10 particles. This unusual characteristic makes this sensor one of the most powerful in the market. I haven’t tested many air purifiers that can detect PM1 particles. For comparison, some popular air purifiers like the Levoit Core 300S or Core 400S only detect PM2.5 particles, so in my view, detecting PM1 particles gives the Shark air purifier a significant edge.

Additionally, I’d like to highlight that this sensor functions in combination with other device features, such as the air quality indicator and auto mode. 

However, there is a potential issue I found about this sensor. It is positioned on the upper side of the device, and it’s integrated in such a way that it’s challenging to access and nearly impossible to clean it. This, I believe, can potentially affect the sensor’s long-term accuracy, making it less accurate over time.

Air Quality Indicator & Air Info

As previously mentioned, the Shark HP102 air quality sensor works in combination with some other features, one of which is the Air Quality Indicator. It is simply a display showing real-time air quality readings from the sensor.

It’s located on the front of the device and can show different air quality data. You can simply select what you want to be shown on the display by pressing the Air Info button.

Each press on this button changes the mode of displaying the current air quality. For example, you can choose Shark to display:

1. % CLEAN AIR: Displays the current air quality rating in percentages. According to Shark, ‘CLEAN AIR uses particulate matter (PM) Air Quality Standards as determined by the EPA to calculate the air quality rating.’ If you see values between 0%–69% on display, the air quality in your home is poor; if it is 70%–84%, the air quality is fair, and if it’s between 85%–100%, the air quality in your home is good.
2. TIME TO CLEAN AIR (min): This is the next parameter that can be shown on display, which shows the estimated time (in minutes) needed for the Shark HP102 air purifier to clean the air in your room. I like this one!
3. PM1: By choosing this option, the device will display the amount of PM1 particles in the air, including viruses and ultra-fine allergens.
4. PM2.5: This option shows PM2.5 particles in the air, including smoke and bacteria.
5. PM10: Displays PM10 particles in the air, including dust, mold, and pollen. I must say that this, along with the Smartmi P1, is the only air purifier that displays the amount of pollen in the air, which I have had the opportunity to test. 

In the table below, you can see what every color on the LED ring means. It is a ring around the display that shows the current air quality lighting in a different color.

Color	Air Quality	Suggestions
Red	Poor (0–69%; 81–430+particles)	A red ring means your air quality is poor, with a high level of particle concentration. For better results, increase fan speed or select Auto Mode.
Amber	Fair (70–84%; 26–80 particles)	An amber ring means your air quality is fair, with a moderate level of particle concentration. For better results, increase fan speed or select Auto Mode.
Blue	Good (85–100%; 0–25 particles)	A blue ring means your air quality is good, with a low level of particle concentration.

In summary, I believe that almost any user of this small air purifier will be even more satisfied when they directly see on the display how the air quality in their home increases when using the Shark air purifier.

Auto Mode

Auto Mode is yet another feature on this device that works in combination with the air quality sensor. Specifically, when in Auto Mode, the Shark HP102 will adjust its fan speed based on the current air quality in the room.

This highly convenient feature allows you to set the air purifier and forget about it while ensuring optimal air quality in your home at all times.

ECO Mode

ECO Mode is another very useful feature designed to save electrical energy costs, save the filter and extend its lifespan.

When the device is switched to Auto Mode and the clean air status maintains a 100% rating for at least 10 minutes, it will switch to ECO Mode. This transition not only boosts energy efficiency but also helps maintain the longevity of your air purifier’s filter.

Brightness

As the name suggests, the Brightness Button serves to adjust the brightness of both the control panel and the display. There are three levels available: full brightness, partially dimmed, and fully dimmed. Each press of the button cycles through these options.

Keep in mind that the brightness indicator and power button will always light; however, their intensity will correspond with the selected brightness setting. This means you can’t completely dim them, but their light will adjust based on your chosen brightness level.

Timer

The Timer function is yet another feature built-in in this air purifier. Essentially, the timer can be set anywhere from 0 to 12 hours, defining the period after which the device will automatically power off.

By pressing the timer button, the selected time is displayed on the front display. This visualization allows you to see the remaining time, any time.

Filter Life Indicator

This indicator notifies you when it’s time to replace the old filter. When the filter life indicator lights up, you should replace the old filter on the device as soon as possible (I have explained the filter replacement procedure in the following part of the review). 

However, this indicator is also used as a button, and by holding your finger on it for 3 seconds, you reset the filter life indicator.

Child Lock

This is a great option if you have small children and want to prevent accidental changes to the set options. 

The option is activated easily by holding your finger on the child lock button for 2 seconds, and it’s deactivated in the same way. When the child lock is active, the device will not respond to pressing any other button.

Warranty

Shark provides a limited warranty for this model for two years, which is standard and in line with other manufacturers. 

What I would recommend to everyone is to register and activate the warranty on the Shark website immediately after purchasing the product.

Room Coverage & CADR

When it comes to room coverage of this small device, things get a bit complicated, primarily because the manufacturer suggests using the device in 500 sq. ft. rooms. However, in a room of this size, this Shark unit only achieves 1 ACH (air changes per hour), meaning it will clean the air in a 500 sq. ft. room once every 60 minutes.

Considering that the industrial standard for ACH is 4.8, we have come to a much different recommendation than what Shark emphasized. In fact, I would recommend using this device in rooms up to 124 sq. ft., as in a room of these dimensions, the unit achieves a 4.8 ACH. This is something you must think about, especially if the room in which you plan to use the air purifier is highly polluted. 

Honestly, I am surprised by the low airflow and coverage of this device, especially since I haven’t come across a large number of air purifiers with this or similar coverage. One that comes to my mind is the Levoit LV-H132, which covers almost identical rooms to the Shark HP102. 

Overall, I conclude that the Shark HP102 is ideal for small rooms such as small bedrooms, small kitchens, offices, kid’s rooms, and similar spaces.

Filtration Technology

The Shark HP102 uses a 3-stage filtration technology consisting of a pre-filter, a True HEPA filter, and an activated carbon filter.

The filter is cylindrical in shape and hollow through the middle. It takes almost half of the device and is placed inside the bottom part of the device.

One thing that I would especially highlight is to occasionally rotate the filter to the other side to ensure even soiling. This is necessary because the airflow openings on this device aren’t spread on all sides, so the filter may become unequal dirty, which significantly affects both performance and the filter’s life.

Pre-filter

The pre-filter is the first stage of filtration, and its main purpose is to capture larger particles such as pet hair, lint, dust bunnies, and more. 

By doing so, this filter prevents these particles from reaching the HEPA filter, thus extending its lifespan and providing more efficient air filtration. 

The pre-filter is practically attached to the HEPA filter and looks like a spider’s web mesh.

Activated Carbon Filter

The Shark HP102 air purifier uses an activated carbon filter as the second filtration stage. This filter is pellet-based, and its primary function is to capture cooking and other odors, volatile organic compounds (VOCs), and formaldehyde. 

Essentially, the use of a pellet-based carbon filter is a significant advantage, as these filters have shown much better performance in tests compared to ordinary fibrous filters coated with carbon. 

Like every air purifier I test, I have also used this one for some time in the rooms where I spend time, and I must say that I’m very satisfied with the performance of this carbon filter. 

It has also demonstrated excellent performance in neutralizing the smell of matches, which I have also tested. It was much quicker and more effective in removing the match odor compared to, for example, the Xiaomi 4 Compact or Renpho air purifiers.

True HEPA Filter

The final and undoubtedly the most important filtration stage in this device is the True HEPA filter. 

The True HEPA filter removes 99.97% of airborne particles as small as 0.3 microns in size. This filter will remove particles such as dust, cigarette and wildfire smoke particulate, mold spores, and more. 

What is interesting/confusing here is that the manufacturer claims that this filter removes 99.98% of particles based on IEST-RP-CC007.3, as small as 0.1-0.2 microns. I have sent an email to Shark to get proof or confirmation of this information. Unfortunately, I haven’t received it, so I can’t confidently state that this filter captures 99.98% of particles.

Nevertheless, the Shark HP102 has shown excellent results in all tests, for which I am certain the True HEPA filter is primarily responsible.

How to Replace Shark HP102 Filter?

The Shark HP102 doesn’t use a washable filter, which means you will need to replace it from time to time. 

The manufacturer advises replacing the filter on average between 6 and 12 months. However, if you notice that the filter has significant dirt, strange odors, or unusual operation, you can change it before it is necessary. 

Shark has a filter life indicator on the control panel, which will notify you when it’s time to replace the filter. Again, if you notice the filter is dirty before the filter reset indicator lights up, I recommend changing it regardless. 

The procedure for replacing the filter is quite simple and consists of just a few easy steps.
