Oneisall PP02 smoke-test showdown: Double filtration that keeps up with the speedsters
Proof that a dual-filter doesn't have to sacrifice speed.
While most air purifiers try to maximize airflow with thin filters, the PP02 prioritizes filter density and allergen clearance. After high-stress testing, it proved it can push air through a massive dual-filter system without falling behind.Stephen Pereyra Published
Verdict - The Oneisall PP02 is a balanced powerhouse
The Oneisall PP02 is a compact, specialized air purifier that strikes an impressive balance between raw filtration mass and clearance speed. In our controlled stress tests involving heavy smoke loads, the PP02 clocked a clearance time of 24 seconds which is impressive considering that the PP02 is pushing air through two full H13 HEPA and Carbon filters. Only a few seconds behind, it kept pace with the compact, airflow-optimized Levoit Core 300-P (17 seconds) while decisively beating the larger, high-CADR Levoit Vital 200S-P (26 seconds). This performance proves that the Oneisall's unique build can handle the heavy resistance of dual filtration without compromising the speed needed for quick air filtration and to keep up with a dynamically contaminated environment that comes with pet ownership.

Unboxing and Design
The Oneisall PP02 arrived in minimal packaging with everything wrapped in plastic. The package includes the main unit, the dual filter sets (pre-installed), and a dedicated lint brush. The brush was a nice addition and can help users maintain the washable pre-filters and extend the life of the primary HEPA filters.
In regards to the filters, the PP02 uses two separate H13 HEPA filters and two separate Activated Carbon filters working in tandem. This effectively doubles the surface area available for trapping pollutants compared to standard designs.
The High-Stress Smoke Test
In testing, the PP02 and its competitors were subjected to a severe challenge: a controlled injection of smoke containing approximately .700 mg/m2 of Total Volatile Organic Compounds (TVOC). This level simulates an environment of marginal air quality concern, such as kitchen smoke or nearby wildfires, far surpassing standard ambient testing. The results highlighted the relationship between filter density and speed:
Levoit Core 300-P: 17 Seconds
Oneisall PP02: 24 Seconds
Levoit Vital 200S-P: 26-27 Seconds
Analysis
At first glance, the Levoit Core 300-P appears to be the fastest at 17 seconds. However, the Core 300-P is a smaller unit with a shorter air path and a single filter, allowing for naturally faster cycling in a small chamber, making the Oneisall PP02's 24-second performance arguably more impressive. It achieved this time while forcing air through double the resistance produced by two full H13 HEPA filters and two activated carbon banks. It is significantly harder to move air quickly through that much filtration media. For the Oneisall to trail the Core 300-P by only 7 seconds speaks more to the design's functionality and the motor's performance.
Furthermore, the Oneisall beat the Levoit Vital 200S-P (26-27s), despite the Vital having a much higher CADR rating of 250 Cubic Feet per Minute (CFM). This confirms that for heavy smoke and chemicals, the Oneisall's dual-intake format processes pollutants more effectively than the Vital's single-filter, high-airflow approach. Another nice feature of the PP02 is the real-time air quality display that helped validate the data in our test. It provided instantaneous feedback, visually confirming the rapid decline in TVOC levels. For users, this feature can offer peace of mind knowing that the PP02 is monitoring the environment and working as expected.
Conclusion
Overall, the Oneisall Double-Sided Air Purifier (PP02) is a specialized tool that holds its own among bigger players. While the smaller Levoit Core 300-P is slightly faster, it lacks the Oneisall's massive capacity. The fact that the PP02 cleared the chamber in 24 seconds, beating the larger Levoit Vital 200S-P, is a testament to its engineering and design. For users looking to free up their environment from allergens, the Oneisall PP02 offers the best of both worlds.
