Daily operation of box air filter

Preparation before installation
Selection and adaptation: According to the size of the space used, the type of air pollution source (such as dust, pollen, smoke, bacteria, etc.), and the expected air quality standards, select the appropriate air volume and filtration accuracy of the box air filter. For example, in smog-prone areas, products with high filtration efficiency for fine particulate matter such as PM2.5 are preferred; The newly renovated house should pay attention to the filter with strong adsorption function of harmful gases such as formaldehyde.
Site investigation: To determine the installation location, it should ensure smooth air circulation and avoid being close to heat, moisture, or strong magnetic fields. Generally speaking, the center of the room or near the air outlet is best, and at least 30-50 cm away from the wall is reserved to facilitate subsequent maintenance and air circulation.
Description of installation steps
Unpacking inspection: After receiving the filter, carefully unpack, check the accessories against the instructions, check whether the appearance of the filter is damaged, or deformed, whether the filter material has delamination, holes, and other defects, and if there is a problem, contact the manufacturer to replace.
Fixed installation: According to the installation guide, use supporting brackets and bolts to secure the box filter to the selected position. For large or industrial filters, professional lifting equipment may be required to ensure that the installation process is smooth and vertical to avoid uneven airflow caused by tilt.
Pipe connection: If connected to the ventilation system, accurately connect the inlet and outlet pipes, use sealing tape or sealant to ensure the connection is tight and without leakage, and prevent unfiltered air from mixing, affecting the overall purification effect.
Essentials of daily operation and maintenance
Operation monitoring: After opening the air purification system, pay attention to the change in the value of the pressure difference meter (if equipped) before and after the filter, and the pressure difference should rise slowly within the specified range during normal operation. If the pressure difference increases sharply, it indicates that the filter material may be blocked seriously and needs to be treated in time. At the same time, observe the air quality of the outlet, such as reduced air volume and odor, which is also an abnormal signal of the filter.
Regular cleaning: Surface cleaning, every 1-2 weeks, gently wipe the filter shell with a soft brush or a slightly wet rag to remove dust stains and avoid infiltration into the interior; Pre-filter cleaning, for part of the box filter with a washable pre-filter, disassemble it every month, rinse it with water, dry it and put it back, which can effectively extend the service life of the main filter material.
Filter material replacement: This is a key link, according to the use of the environment and frequency, the general HEPA filter material is replaced every 6-12 months, and the activated carbon filter material is replaced in 3-6 months (after adsorption saturation, it needs to be replaced in time to prevent secondary pollution). When replacing, strictly follow the instructions, wear gloves and masks, and properly dispose of waste filter materials to avoid dust pollution.
Energy saving and life Extension Tips
Reasonable setting of wind speed: Adjust the wind speed gear of the air purification system according to the actual demand, and do not use the maximum wind speed when not necessary, which can reduce energy consumption, reduce the burden of the filter material, and extend its working life.
Environmental optimization: Keep the room clean and reduce dust sources, such as regularly sweeping the floor and wiping furniture; In hazy days or dusty weather, close the doors and Windows to avoid excessive dirty air pouring in so that the box air filter works more calmly and efficiently.
By mastering these daily operation details of the box air filter, it can continuously and stably filter the dirt for us, deliver fresh, create a healthy and comfortable breathing space, and protect the respiratory health of family members, colleagues, and every user.
