While air purifiers can often run for months without needing your attention, most of them aren’t entirely maintenance-free. Any air purifier with an internal filter will require at least an occasional filter change. Although it may seem like a small matter, changing the filters in your air purifier at the right time is a key aspect of getting the cleanest air possible in your home.
As filters age, they can gradually become filled with contaminants. This is especially true of HEPA filters, which capture solid particles in a filter medium. Over time, the filter will have less and less capacity to capture new impurities, causing it to gradually become less effective. When this happens, your air purifier may struggle to deliver clean air as it should.
When to Change Your Filters
Unfortunately, there’s no standard schedule for air purifier filter changes. Some manufacturers recommend changing filters once a year, while others may recommend every six months. Some filters can even go multiple years between changes. Ultimately, the proper filter maintenance schedule depends on the type of filter and the manufacturer. To find the correct schedule for your air purifier, consult and follow the instructions provided by the manufacturer in your air purifier owner’s manual.
Adding to the potential confusion is the fact that many air purifiers today have multiple filters. An air purifier with a prefilter, a HEPA filter and a carbon filter may require changes at three entirely different intervals. This makes it even more important to carefully track your filter changes to stay in line with the schedule recommended by the manufacturer.
Checking Your Air Purifier’s Performance With an Indoor Air Quality Monitor
Another great way to make sure you’re getting the most out of your air purifier is to use an indoor air quality monitor. These devices track the air quality in your home, allowing you to see how well your air purifier is performing. With an air quality monitor, you can be sure that your air purifier is doing its job and easily see decreases in air quality that may indicate that your filter is no longer functioning as it should. Some of our top indoor air quality monitors are listed below:
The Simple Way to Keep Track of Your Maintenance Schedule
With most air purifiers only needing occasional filter changes, it’s easy to let maintenance slip your mind. Luckily, there’s an easy solution in the form of our Filter Change Reminder tool! With this simple tool, you can register your air purifier and receive email reminders uniquely targeted to its maintenance schedule. This tool also allows you to register multiple air purifiers, making it simple to track filter changes even if you have several different units.
