When Should You Replace Your Air Purifier Filters?

Your air purifier collects a portion of irritating airborne particles in your home - but then what happens to those particles? If you've ever been curious about where dust, pollen, pet dander and other particles go once they're trapped by your purifier, the answer is simple: They get stored in the filter. That's why it's so important to clean your filter or replace it, depending on which type of air purifier you have. When the filter is full, the air can't properly pass through, which means the device won't function efficiently. 

But when is the right time to replace the air purifier filter? Here are some suggestions to consider. 

"A permanent filter doesn't need replacing."

Permanent vs. Replacement
Before you can decide if it needs to be replaced, you must first determine whether it is a replacement or permanent one. As the name suggests, a permanent filter doesn't need replacing - instead, take it out and wipe away the particles periodically to ensure that air can properly pass through it. Then, simply place it back in the air purifier. Some devices let you know when it needs to be cleaned. However, note that eventually, even permanent filters - or the air purifier itself - will need replacing in order to run as efficiently as possible. Permanent filters should be cleaned every 3 months depending on usage.

If you're using a replacement filter, follow the next steps to determine when it should be changed.

Consider the Type of Replacement Filter
There are different types of replacement filters, and many of them use different technology to trap irritating particles. Some include carbon to attract dust and other allergens and neutralize odors, while others use HEPA technology to trap some of the tiniest allergens. Each type of filter is effective and has its own advantages to removing irritating particles, and in turn, has a different life span. On average, replaceable filters should be replaced every 3-6 months depending on usage and filter type.

Listen to Notifications
While you can rely on each type of filter's estimated longevity, it's not always so clear. That's why some devices are equipped with technology that lets you know when a filter change is needed. Depending on the device, it will either let you know with a signal implanted on the purifier, or it will deliver a notification to you via your smartphone or tablet. It's important to listen to these notifications and not put off replacing the filter so you can rest assured that the device is working at its full capacity. Some devices make the process easy for those with busy schedules, and allow you to order new filters straight from your mobile device the moment you get a notification to change them.
