Air Purifier Filter Changes: Everything You Need to Know

If you’re using an air purifier in your home, it’s easy to forget about it on a day-to-day basis. While air purifiers shouldn’t need much maintenance, one task that’s very important is changing their filters on a regular basis. Here’s what you need to know about air purifier filter changes, when it’s time for a new filter and how you can easily keep track of your filter change schedule with a little help from US Air Purifiers.


  What Happens When a Filter Gets Too Dirty?


As air purifier filters are used, they pick up contaminants from the air. The result is that they gradually become loaded with these contaminants, making it harder for them to filter effectively. The biggest problem caused by dirty filters is a reduced supply of clean air. When filters are clogged, less air will be able to pass through them. This means less clean air will come out. Once the filter becomes too dirty, the space your purifier can cover will gradually begin to shrink.


Dirty filters can also run up your energy bills. As your purifier has to work harder to pass air through, it will become less energy efficient. If you leave an old filter in too long, it can markedly increase your air purifier’s energy consumption. Wait too long, and you’ll be stuck with higher energy bills and lower air quality.


Finally, a filter that gets dirty enough could become a source of airborne contaminants itself. Toxins from bacteria and mold trapped in the filter could be distributed by the fan, allowing them to be breathed in. This usually only happens in extreme cases where filters are left in long after they should be changed, but it is something to keep in mind.


  How Often Should You Change Your Air Purifier Filters?


The question of how often to change air purifier filters comes up quite often, but it’s a question without a single answer. Different air purifiers require filter changes on different schedules. Each air purifier comes with a recommendation from the manufacturer on how often its filters should be changed. This recommended schedule should be followed as closely as possible in order to ensure proper function.


It’s also worth noting that many air purifiers have more than one filter. Each filter in your model will likely be on a different changing schedule, a fact which can sometimes make it difficult to keep up. For example, let’s take the popular Amaircare 3000 VOC, which uses a pre-filter, a HEPA filter and a carbon canister. On this particular model, the pre-filter should be changed every 3-6 months, while the HEPA filter lasts 2-5 years and the carbon canister lasts 1 year.


With that said, it’s absolutely essential to know the changing schedule for your specific model. By sticking to this schedule, you can ensure proper operation and keep your air as clean as possible.


  How to Keep Track of Filter Changes


There are several different ways to know it’s time to change your filters. The simplest method is to buy an air purifier with a filter change indicator. This feature will tell you exactly when it’s time for a filter change, preventing you from having to track the time since your last change on your own. Many leading air purifiers offer built-in filter reminders, including the Amaircare 3000, Blueair Pro L and the Rabbit Air BioGS 2.0.


Can You Measure Air Purifier Filter Performance?


Even though regular filter changes should keep your air purifier in peak working condition, many users still want to be able to measure performance independently. Fortunately, this can be done with the use of an indoor air quality meter. These meters will give you data about your home air, allowing you to see if your purifier is really doing its job. If you notice the air quality beginning to diminish, it may be a sign that you have a filter in need of a change.


Our most popular indoor air quality meter is the Foobot unit. This meter has a simple color-coded display that will give you a basic picture of the air quality in your home. Via a smartphone app, you can also get more in-depth data and recommendations for improving your overall air quality.


Are There Ways to Extend Your Filter Life?


Because replacement filters cost money, many people understandably want to find ways to keep using their old filters for longer periods of time. The one proven way to extend the life of a filter is to minimize the amount of contamination it has to deal with. By reducing dust in your home, for example, you can keep a HEPA filter cleaner for longer. Eliminating contaminants at their source also has the advantage of making your home healthier overall, so it’s well worth doing in any event.


With that said, all air purifier filters will need replaced eventually. Waiting too long or trying to squeeze extra life out of an old filter may put your air quality at risk. When in doubt, it’s better to change your filter than to put it off.


What About Filterless Air Purifiers?


In addition to the standard HEPA and carbon filtered models, there are some air purifiers that remove contaminants without the use of a filter. Filterless air purifiers typically use a thermal core to remove solid contaminants from the air. This system can be useful for bacteria, viruses, mold spores, dust, dander, pollen and other particulates, but it doesn’t have any ability to filter VOCs, gases or odors. So, if you’re looking for something that will focus on particulates only, a filter-free model may be a decent choice.


Want to Make Air Purifier Maintenance Effortless? Use Our Filter Change Reminder Tool!


As you can probably tell by now, there are few things more essential to keeping your air purifier running properly than changing its filters on the right schedule. The problem, though, is that many users don’t keep careful track of filter changes or monitor their units to see when the filter change reminder light comes on. Fortunately, we offer a free, easy-to-use online tool that can make tracking your filter changes as easy as pressing a few buttons.


With our Filter Change Reminder tool, you can register your air purifier with us and receive an email notification when it’s time for new filters. The tool uses the intervals suggested by manufacturers to keep track of your filter changes. When it’s time for a new filter, our till will automatically notify you, making it easy to remember. Forget writing down your last filter date or tracking the time on a calendar, because we have you covered!


Even better, we’ve recently made some huge improvements to this tool. At one time, we only had the ability to register one air purifier per email address. Now, you can register several air purifiers and track each one individually. This means that all of your notifications can go to the same email address, making it much easier to keep track of them as they come in.


If you own an air purifier, proper filter maintenance is an essential part of keeping it working and keeping your air clean. By executing air purifier filter changes on the right schedule and monitoring your purifier’s performance, you can make sure that you’re always breathing only the cleanest air.
