Not all things good have to be expensive. PARTU BS-03 True HEPA air purifier is exactly at the end of the affordable spectrum without having to sacrifice on the filtration. The distinctive black exterior with a top turbine outlet is very pleasing to look at and you can hardly tell it is an air purifier. At a compact cylinder shape of 9.6 inches in diameter and 17 inches in height, it is highly suited for places with bad air yet without the luxury of space. Complementing that is the lightweight 3.2 pounds that makes room to room purifying and for traveling an effortless task.

Moving to usability, PARTU BS-03 front controls are clearly laid out and easily visible for a quick setup. You can adjust the fan speeds, reset the filter change indicator, lock the controls from children and pets, and light dimmer button that turns off indicator light for night use. Adding all that is a fragrance sponge slot underneath the turbine that you can insert your favorite essential oil like Citrus, Honeydew Melon, Musk, Vanilla, Orris or Vetiver to freshen the air.

Overall PARTU BS-03 True HEPA air purifier surpasses ur durability expectation. It is very well fitted despite the inexpensive price tag. For even better assurance of its quality, PARTU BS-03 is approved by FDA, ETL, FCC, and comes with 2 years manufacturer warranty plus lifetime after-service support.

Put aside the affordable price tag, PARTU BS-03 True HEPA air purifier 107 square feet room size coverage is not spectacular by any means. It is only meant for close-range purifying such as bedside use, work desk, washroom, kitchen, or small studio room with limited space. While fresh air is guaranteed, the airflow delivery rate is also under par despite having an adjustable 3 fan speed. With the lack of autonomous mode, we suggest leaving it at max speed to get the best out of the air purifier.

Filters And Performance

On the filtration end, PARTU BS-03 manage to squeeze in a 3-stage HEPA system that should cover most types of pollutants in the home. The outer pre-filter is designed to trap large particles like dust, hair, debris while protecting the HEPA filter from unwanted clogs. In return, the protected True HEPA filter can capture 99.97% of microscopic particles as small as 0.3 microns such as dust mite, pet dander, mold spore, mildew, and pollen. For smoke particles, you have a dedicated carbon filter that neutralizes gaseous pollutants and odors coming from cooking, cigarette, pets, and other house detergents. Overall the filtration does what it can do, but the efficiency and usability are limited by its size and airflow distribution. you

Noise And Energy Usage

38-59 dB
PARTU BS-03 power consumption
Power consumption
12 W
For the high airflow output, 32 - 62 dB(A) noise level is actually a lot quieter than a similar range model. This is because the low-density filter allows air to flow at a much lower pressure. That said, you can hardly tell the differences in real-life situations. Noise is whisper-quiet at low speed, normal at medium speed, and audible moving up the notch. Thanks to the advanced fan setup, 15 - 100 W power consumption is reasonable given the airflow return. Without default auto mode, you have to manually keep the speed low to help reduce electricity use.

^ Replacement filters/ estimated cost
For less than $50 dollars, there are not many faults you could find in PARTU BS-03. It comes with a premium True HEPA filter and carbon filter for small room air cleaning. For those that like to use essential oil to help them sleep, PARTU BS-03 is also the very few options that come with this feature. As for the annual filter replacement, expect a recurring 50 to 70 dollars in cost given the short filter lifespan. Not the lowest for a compact air purifier, but still within an acceptable price range.
PARTU BS-03 True HEPA air purifier is not a household brand like Honeywell or Hamilton Beach. So it is practically impossible to find one in retailers like Walmart, Costco. We can't even find PARTU's official website at the point of this writing. So Amazon is the best place to shop for official PARTU air purifiers with plenty of color variants to choose from. You will enjoy the perks like free shipping, 30 days return policy, and bundled discount.

Levoit Core 300 True HEPA Air Purifier Review

LEVOIT Core 300

An identical 3-stage filtration but comes with better purifying coverage, filtration, and a built-in timer. The trade-off is LEVOIT Core 300 costs almost double PARTU's selling price.
Hamilton Beach TrueAir Compact Pet Air Purifier 04384 Review

Hamilton Beach 04384 TrueAir Compact Pet

Same price region, but uses a permanent HEPA-grade filter that is also washable. You will save up on the filter cost but will have to sacrifice the performance.

  • Very compact and lightweight (bedside table friendly).
  • Genuine True HEPA filter and carbon filter that effectively captures dust, mold spore, pollen, pet dander, cigarette smoke, and cooking smell.
  • Low energy, whisper-quiet operation.
  • Essential oil compatible with plenty of fragrance options.


  • Limited airflow delivery rate and purifying coverage.
