Air purifier machine

Start with the room size. The AF 20 model is suitable for areas up to about 40 m², while the AF 30 is designed for medium-sized rooms. Check the unit’s dimensions and weight, and note that it includes a one-year warranty. Look for a PM2.5 display, temperature and humidity readings, and functions like Auto Mode, Sleep Mode, and a timer. Choosing the right model helps improve air quality in the space you use it and creates a more comfortable environment.

Look for a multi-layer filtration system with activated carbon to absorb odors and fine particles, plus a PM2.5 display to monitor air quality. A replaceable filter helps keep the unit working efficiently over time. Also check power consumption and noise level for comfortable operation during work or sleep. These features give you clear control of performance and match your everyday needs.

The listed models offer touch controls and a display screen, along with an automatic mode that adjusts fan speed based on air quality. The AF 30 highlights a PM2.5 screen with temperature and humidity display, plus Sleep Mode, a timer, and a safety lock. The AF 20 offers similar control but with a simpler interface. These differences allow you to choose the model that gives you precise control and better adaptation for daily home or office use.

Both the AF 30 and AF 20 come with a one-year warranty from the authorized seller, covering manufacturing defects during normal use. The warranty provides after-sales support and adds confidence when purchasing. Be sure to check the warranty documents at purchase to confirm coverage details, support duration, and service availability.

PM2.5 measures fine particles in micrograms per cubic meter. The higher the number, the more polluted the air. The screens show the reading digitally with a color code to indicate the status quickly, helping you decide whether to run the device or increase fan speed. Use this reading as a simple guide to adjust modes in bedrooms or work areas to reduce exposure to harmful particles.

Review the unit’s weight and size to make sure it fits your space without overcrowding. Confirm it has a clear user interface and functions like timer and Sleep Mode, and ensure there is reliable after-sales service or warranty. Choosing well-known brands can also offer design options that match your décor, and may give you the ability to switch between different modes to maximize air purification effectiveness in your room.
