Millions of people around the world rely on room air cleaners (sometimes referred to as air purifiers) to improve indoor air quality and reduce the presence of allergens. They are a valuable tool that can help ease your allergy symptoms and keep homes cleaner.
Like most appliances, how you operate and care for your air cleaner will affect its performance. Take these steps to ensure that your air cleaner continues to operate at a high level:
Change the filter regularly: Your air cleaner’s use and care manual will recommend how often you should change your air cleaner’s filter. Keep in mind that these recommendations are based on the manufacturer’s testing. How often you should change the filter also depends on how much you’re using the air cleaner and the level of pollutants in the air. If you have your windows open frequently, for example, you may need to change the filter more often. Check your filter regularly. If the filter is changing color or if you notice that a drop in the level of air coming out of the air cleaner, it’s probably time for a new filter.
No filter? Some air cleaners don’t require filters, relying instead on an electrostatic precipitator (ESP), which charges particles and attracts them to a plate. Clean those regularly. Check your use and care manual for specific cleaning instructions.
Clean the outside: Some manufacturers recommend using a vacuum to remove dust from the outside of the air cleaner. Vacuum or gently clean the dust from the outside of the air cleaner when you notice a buildup.
Take care of the rest of the room: Air cleaners are only part of the equation if you are seeking cleaner indoor air. Do a thorough cleaning of the area and vacuum regularly to remove particles so they are not kicked back into the air you breathe.
Change your furnace filter: If you change your furnace filter regularly, you might not have to change the filter in your air cleaner as often. However, a furnace filter is not a substitute for an air cleaner because it is designed to trap large particles. In addition, it is common for particles to miss the furnace filter and end up inside the home.
Give your air cleaner room to breathe: It might be more convenient to place an air cleaner against a wall and in a corner, but that sort of placement will restrict airflow and reduce performance. Move it toward the center of the room and operate it in an area free of obstructions. The more air that goes through the air cleaner, the more pollutants it will remove.
Shopping for an air cleaner? Here’s how to make the right choice
If you are shopping for an air cleaner, you will likely come across models that use different types of technologies to clear the air. More important than the method the air cleaner uses is whether the air cleaner is appropriate for the size room in which it will be used. Look for the AHAM Verifide® mark on the air cleaner packaging. The mark means the air cleaner has been independently tested for its ability to remove tobacco smoke, pollen and dust. The suggested room size for the air cleaner will be noted prominently on the label.
