Comparative analysis of the efficiency of different models of air recirculators

Bactosfera bactericidal units can be found today in a wide variety of areas: from beauty salons, offices, and residential apartments to kindergartens, schools, and medical institutions. This wide range of applications is explained by the fact that these recirculators really disinfect the air well and allow effective maintenance of a safe environment in places with large crowds of people.

Disinfection occurs due to ultraviolet radiation produced by special bactericidal lamps. They emit electromagnetic waves in the bactericidal range of 205–315 nm, which ensures the destruction of microorganisms' DNA and RNA, rendering them unable to reproduce. The devices are powered from a 220 V, 50 Hz network, and connection is usually carried out through a ballast (starter) unit.

Recirculators are completely safe for humans. Disinfection occurs inside the housing, so ultraviolet rays do not escape outside and do not affect people in the room. This allows the devices to be used in medical institutions, offices, schools, salons, and other places with a constant presence of people.

BactoSfera ORBB 100 30x1

Model with a single powerful 30 W lamp, capable of treating air in a room up to 60 m² — larger than the other models in our comparison. Airflow capacity of about 100 m³/h allows rapid air circulation through the device. Lack of a timer and lamp indicators makes operation less functional but simpler and more intuitive. Suitable for large rooms, offices, or halls with moderate occupancy.

Pros: large coverage area, powerful lamp, simplicity.
Cons: fewer control functions (no timer, no indicators).

BactoSfera ORBB 15x2 Gorizont

Model with two 15 W lamps. Sufficiently high airflow capacity — 200 m³/h, which ensures a fast recirculation cycle. Equipped with a programmable timer and lamp status indicators, which is very convenient for daily use. Effective in rooms up to 30 m², most often in offices, small workspaces, or classrooms.

Pros: convenient control functions, even lamp distribution, high airflow speed.
Cons: coverage area is smaller than the 30 W model.

BactoSfera ORBB 15x3 Vertical

A more powerful version with a three-lamp block (3 × 15 W), which increases the overall UV-C exposure. This design allows for more effective air treatment faster (≈ 2.4 min per 1 m³) with the same airflow capacity of 200 m³/h. Equipped with a timer and indicators — convenient for use in high-traffic facilities. Intended for rooms up to 30 m² but provides more intensive air treatment.

Pros: high lamp power, fast processing cycle, convenient functions.
Cons: slightly higher cost and excessive for small rooms.

Conclusions

ORBB 100 30x1 — the best choice for large rooms (up to ~60 m²). Low cost and sufficient power.

ORBB 15x2 Gorizont — optimal for small and medium rooms (up to ~30 m²), balancing recirculation speed and functionality.

ORBB 15x3 Vertical — suitable for the same rooms up to ~30 m² but provides more intensive air purification due to three lamps. Cost is slightly higher.

All models are designed for safe use in the presence of people, equipped with ozone-free UV-C lamps, and suitable for medical, educational, and household environments. Purchase them at the best price on the official manufacturer’s site bactosfera.ua and avoid counterfeits.
