What are the dangers of not replacing the purifier filter for a long time?
The filter element of the purifier is the core component to maintain clean air. If it is not replaced for a long time, it will bring many hazards, not only affecting the purification effect, but also may have a negative impact on health and equipment. The following are the specific hazards:
1. Decreased air quality
• The filtering effect is greatly reduced: After the filter element is saturated with adsorption, it cannot effectively intercept pollutants such as dust, PM2.5, pollen, and odor in the air, making the purifier "useless".
• Secondary pollution: Dirty filter elements may breed microorganisms such as bacteria and mold, and become a new source of pollution, affecting the indoor environment.
2. Increased health risks
• Affected respiratory system: Pollutants in the air cannot be filtered, which can easily induce coughing, rhinitis, asthma and other problems, especially for children, the elderly and sensitive people.
• Harmful gas residues: The long-term presence of volatile organic compounds such as formaldehyde and benzene can cause damage to the human nervous system and internal organs.
3. Loss of purifier performance
• Reduced air volume: When the filter is clogged, ventilation is poor, the purifier wind speed decreases, and the overall purification efficiency is affected.
• Increased motor load: To maintain output, the equipment needs to operate at a higher power, which may cause motor damage or shorten its life in the long run.
• Increased operating noise: Clogged filters will increase the fan load and the noise will increase accordingly.
4. Increased cost of use
• Increased energy consumption: The purification effect decreases, the equipment needs to run for a long time to be effective, and the electricity cost increases.
• Delayed replacement leads to maintenance: When the filter element is severely clogged, it may damage the entire machine components, increasing the cost of maintenance or replacement.
Recommended filter replacement cycle
|
Filter Type |
Recommended replacement cycle |
|
HEPA filter |
Replace every 6-12 months |
|
Activated carbon filter |
Replace every 3-6 months |
|
Primary filter (washable) |
Clean once a month and reuse |
It is recommended to flexibly adjust the replacement time according to the frequency of use and environment (such as whether there is smoking, the presence of pets, areas with severe air pollution, etc.) to ensure the long-term and stable operation of the purifier.
