Air ionizers are a great way to keep your home's air clean and free of pollutants. But how often should you service or replace them? It depends on the specific filter you have, but as a general rule, replaceable HEPA filters should be changed every 6 to 12 months, depending on air quality. Some manufacturers recommend cleaning purifiers every two to four weeks, while others may require more time between cleanings. If your filter is exposed to excessive dirt or pollution, it may need more frequent cleaning.
If you're in the market for an air purifier or want to upgrade your current system, consider buying one with an automatic sensor. This will tell you when the air filter needs to be changed or cleaned. Air filters that can be cleaned are commonly called washable air filters. Depending on the make or model, a light will come on or an alarm-like noise will be heard when the filter needs to be replaced. In recent years, conversations about air quality have increased due to the pandemic.
This has caused a surge in demand for air purifiers as people become more aware of indoor air pollution levels. According to the Environmental Protection Agency (EPA), indoor air can be two to five times more harmful than outdoor air. Those who suffer from asthma or allergies are the best judges of when an air filter needs to be replaced. Air filters that work with air purifiers can reduce symptoms and outbreaks of allergies and asthma. Quality air purifiers can remove and clean indoor air of contaminants, allowing you and your loved ones to protect yourself from respiratory conditions.
In addition to regular air filter maintenance, you can extend the life of an air purifier by cleaning the outside once a month and avoiding running it at full speed for extended periods of time. HEPA-based air purifiers, activated carbon air purifiers, and electrostatic air purifiers will need filters. UV air purifiers, ionic air purifiers, and ozone generators will not need filters, although there are hybrid devices that contain several air purification technologies. When the air purifier constantly filters particles from indoor air, dust and pollen can build up over time. To ensure your home's air remains clean and free of pollutants, it's important to service or replace your air ionizer regularly. If your device doesn't have built-in indicators that tell you when it's time for a replacement filter, pay attention to any changes in your home's air quality and take action accordingly.
