Full Review
The PARTU BS-08 is a small air purifier with an affordable price that makes it so popular. The company is based in China, but this isn’t an issue since most parts, as well as all the devices, are assembled in China.
This air purifier is designed for small spaces such as bedrooms, kids’ rooms, small offices, or small kitchens. It’s operated through touch buttons located on the top of the air purifier.
The PARTU BS-08 air purifier is one of the quietest on the market and is highly recommended for people who have trouble sleeping in noisy environments. However, the most important info about this air purifier is its CARB certification, mostly because it has an ionizer built in. This certification means the device has passed all of California’s strict laws, making it available for order in California.
Design
Design is probably the most significant advantage of the PARTU BS-08 air purifier. Black color and impressive touch panel make the BS-08 air purifier very attractive. It is not a dull old box; it is an innovative air purifier with lights and exciting shapes. The night light is handy since you can choose from seven different colors.
It is built with plastic; you can feel matted plastic, which, unfortunately, isn’t of high quality. But then again, this is a Chinese brand, and we know that to fight the competition, you need to be affordable.
The size of the PARTU BS-08 air purifier is small, which means portability. There are no handles to hold it, but even without handles, you can quickly move it. The black color is also disadvantageous for some environments because we know that the black color does not fit all spaces. If the air purifier were white, we could say that it could blend in any environment.
The air intake is at the bottom, and it is small compared to other 360-degree air intake air purifiers. This low air intake means that airflow is not the best and that this air purifier may have trouble in a larger room. The good thing is that air is released on the top, which allows a good spread all over the room.
Touch Buttons
Touch buttons are large enough and very responsive even to the slightest touch. The touch panel is not exactly on the top; it is curved on one side under 45 degrees. With every press of the button, you should hear a beep. This beep sound is confirmation that your order is being served. Some air purifiers are not responding with a beep; I find it natural to have a sound alert and to actually know that something has changed in the way the air purifier is working.
Let’s take a look at what each button does. The power button, as the name says, will bring power, and the air purifier will start working. It will automatically work on the first speed. Also, the lights will be turned on. Fan speed adjustment is used to change the speed from low to medium to high.
Night light, as I already mentioned, is a very nice option that allows you to change the light color. You can choose from seven different colors. As soon as the air purifier starts, the night light is on. Lights are changed in a circle, and once you see the desired light color, you need to press the night light button, and from then, only that color will be on. If you press the night light button again, the night light will shut down. If you hold the night light for 3 seconds, all lights on the air purifier, including the night light, will shut down.
Anion mode is a filtering mode that sends six million anions in the air to clear the air. This mode is, by default off, so you need to press the anion mode button to start it.
Filter replacement light is what most modern air purifiers have. It is used as a visual indicator that will let you know when filters need to be replaced.
PARTU BS-08 remembers last used settings and, on the next run, will start in the same settings. It will work at the same speed; however, lights will always be turned on no matter if on the last shutdown they were turned off.
Size and Dimensions
PARTU BS-08 has 6.6lb and is a kind of light model that can be easily moved. It is also small (9.6 x 9.6 x 17inches), which allows a proper placement even in small spaces like a table, desktop, kitchen table, or any other furniture that can hold an air purifier.
Accessories and Parts
In the package box, you should get one air purifier with a 3 in 1 filter and user manual. Read carefully through the user manual to make sure everything is set right before the first run.
Features Overview
Certified HEPA Removes Allergens
The PARTU BS-08 air purifier uses the HEPA filter, and even if it is small in size it is powerful enough to remove most of the allergens from the air. It can also remove some more abundant viruses, which nowadays is especially beneficial.
Ultra Quiet
The minimum noise on this air purifier is 25dB according to official results; I did my own testing, which you can read under the noise section. We can agree that at low speed with PARTU BS-08, even the light sleepers can get a good night’s sleep.
No Ozone
It emits no ozone when in normal mode. However, when you turn anion mode and six million anions are released in the air, you will probably sense some ozone.
But, even then, ozone levels aren’t high enough to cause any harm, which is confirmed by the CARB certificate. Still, different people react differently to things, so to stay on the safe side, use anion mode when you are not in the room.
Filtration Technology
Filtration with PARTU BS-08 is simple; lousy air is sucked in and pulled through three filters.
The pre-filter is the first filter and removes large particles.
The second filter is the primary filter, HEPA. It removes 99.97% of airborne particles, which means nothing much will be left in the air.
The last filter layer is an activated carbon filter, which eliminates bad odor. Don’t expect wonders in bad odor removal because we know that size of the carbon filter matters.
PARTU HEPA filter captures 99.97% nature allergies, pollen and mold, protect you against running nose and sore throat.
In small air purifiers, activated carbon can’t be large, so odor removal is not the best. But BS-08 air purifier has anion mode, which is excellent against odors.
How to Replace Filter on the PARTU BS-08?
Filter replacement is required when the filter replacement indicator shows an alert, which occurs every six months on average. The process is easy, and everyone can do it.
Put the air purifier horizontally and open the filter cover by turning it counterclockwise. Take the old filter out and put it inside the new one. Return the filter cover back and seal it. And that’s about it.
It is also recommended to periodically use a soft brush and remove dirt from the filter. Never use water or hard tools on the filter. HEPA filters, even with pre-filter, are sensitive, so be careful when brushing.
As soon as you replace the filter, you need to rest the filter indicator by pressing it for 3 seconds. As soon as the light is off, you know that the filter replacement indicator is reset.
For a longer HEPA filter lifespan, you should periodically clean pre-filter.
Noise Test
I did my own experiments on noise. I can confirm that this air purifier is very quiet at the first speed. It is ideal for a bedroom. However, at the third speed, the air purifier is very loud, but at that speed, it is also the most effective.
In the table below, you can see all the results of the test and keep in mind that my noise measuring tool is considering “A” decibels in the equation, which means that results may be different from official ones, which does not mean either of us is wrong.
| Speed | Value (dBA) |
|---|---|
| Speed 1 | 40.7 dBA |
| Speed 2 | 47.4 dBA |
| Speed 3 | 58 dBA |
Performance Tests
The recommended room size for the PARTU BS-08 is 160 sq. ft., but I tested it in a bit larger room, and even there, it showed okay results.
However, I must say that I’m not satisfied with its ability to neutralize bad odors and remove smoke in the room.
All tests are real-life events, and I didn’t do any laboratory tests, so keep that in mind when interpreting these tests.
Always start the air purifier on the third speed. Let it run from some time on third speed then put it on a lower speed to reduce noise.
194 sq. ft. Room Test
As you see, this room is 34 square feet larger than the recommended dimensions, but the PARTU did a great job here.
With anion mode off, the air purifier reduced AQI from 86 to 10 in only one hour. That’s 88% better air. I left it to run for another 30 minutes, and AQI dropped to 9.
| # | Starting Baseline | After 60min |
|---|---|---|
| PM 2.5 | 64.4 | 7.3 |
| PM 10 | 90.2 | 10.2 |
| Particles | 93428 | 10663 |
| AQI | 86 | 10 |
Operating Costs
Just like other small air purifiers in this category, this one also is a low-energy consumer. It can use 35W maximum. At first speed, it uses only 7.2W. On standby, it doesn’t use energy.
In other words, you won’t even notice a change on a power bill. If you let it run for a whole day for 30 days, you will pay less than 3 dollars (2.8$) if the price for electricity is 0.12$/KWh. The highest operating costs are filter replacement and the purchase of additional filters.
| Speed | Power Usage (W) |
|---|---|
| Speed 1 | 7.2W |
| Speed 2 | 13.4W |
| Speed 3 | 32W |
| Stand-by | 0W |
However, 35W for such a small airflow is too much, and I think engineers from PARTU could do a better job optimizing the motor power usage.
I’m so annoyed. I bought the Partu BS-08 almost three years ago bc of a California fire close by. After it arrived, we didn’t use it bc we left the area until the fire smoke was gone. I just got it out of storage three months ago. I used it about six hours a day during the past three months. I had cleaned out the filter twice. The second time, 3 days ago. After I put it back together and plugged it in, it wouldn’t work. Nothing. Had a maintenance friend look at it. Won’t turn on. Used very little. No company to complain to. Any thoughts?
Sorry to hear that it stopped working when it is the most needed.
I suggest contacting them on partu4u@outlook.com email or through Amazon. They don’t have a website, and their Facebook page seems inactive, but you can send them a message on Facebook (you might get a positive answer).
