Partu BS-03 Design and Size

The Partu BS-03 looks chic and robust for its price, at least initially. Partu has opted for a plastic case that comes in black color. It appears to use a cylindrical design, with the top air outlet leaning on front for more direct air flow to users.

This air purifier is compact with the height of only 11.4 inches, and the width of 6.3 inches, which is a bit smaller than the Partu BS-08. At just 3.4 lbs, this is one of the lightest air purifier you can get for your bedroom. If you prefer a more solid option, you should look for the Partu BS-07 or Partu BS-10.

Partu BS-03 sports a simple bottom-to-top air flow system concept, and underneath the top air outlet is a space for adding essential oils. As a result, the device can both purify the air and release fragrance to create wellness.

Partu BS-03 Filters

Partu BS-03 uses a simple-yet-reliable 3-stage air cleaning system, which is a plus for an air purifier that is under $50.

  1. Pre-filter – The fine preliminary filter can remove any large objects with size bigger than 100 microns, like pet, lint and fur.
  2. True HEPA filter – Traps 99.9% of any particles as small as 0.3 microns, like pollen, mold spores, pet dander, dust or dust mites.
  3. Activated Carbon filter – Removes cigarette smoke, odors and cooking smells.

Partu BS-03 is certified by the California Air Resources Board (CARB) to meet the safety of ozone emission, as the ozone emission concentration limit is only 0.05 parts per million (ppm). It is reasonable as the air purifier only uses mechanical filters, so it could be completely 100% ozone-free.

I used the same test for all Partu devices, in a room of 100 square feet and the duration of 1 hour. The Partu BS-03, with the smallest size, had the lowest score of only 99.9% efficiency for trapping any particles down to 0.3 microns.

Partu BS-03 is mainly an air purifier for bedroom, so it needs to be very quiet when operating. On lowest speed, the noise level is measured to be only 38 decibels (db), which is even quieter than the library.

Partu doesn’t have a website for their products, so it is quite difficult to learn about their customer service. We don’t know where to contact this manufacturer for support, either via phone or email.

It seems Partu will provide a 2-year warranty for all their products, but if you need full refund, you must refer to return policy of the retailer that you’ve purchased from.
