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 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 situation. 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 at low to help reduce the electricity use.

^ Replacement filters/ estimated cost
For less than $50 dollars, there is very little fault 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 official website at the point of this writing. So Amazon is the best place to shop for 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.

PARTU BS-03 VS the challengers

LEVOIT Core 300 True HEPA Air Purifier

LEVOIT Core 300

An identical 3-stage filtration but comes with better purifying coverage, filtration, and timer. The trade-off is LEVOIT Core 300 cost almost double of PARTU selling price.
Hamilton Beach TrueAir Compact Pet 04384

Hamilton Beach TrueAir Compact Pet 04384

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

Final thoughts on PARTU BS-03

Bring to a conclusion, we are happy with Blueair 605 overall performance bar the price. It seems 83% of the 4-5 stars reviewers agreed with us. Most praises coming from the abundances of airflow that pulls in anything from the path. The outstanding smoke and odor filtration are another regular praises. Lastly, people love how Blueair manage to make a difference against seasonal allergies. As for the bad part, there are around 10% for the unhappy 1-2 stars reviewers. Most have their concern on the noxious chemical smell emitted from the air purifier. Other minor complains include Wi-Fi pairing problem, faulty unit, and filter replacement cost. Compare to the advantages/ disadvantages, there are definitely more things to look forward. We did not encounter any of the above issues in our test unit. If you have a concern with the chemical smells, contact Blueair before purchasing one.
