Everything You Need to Know About Air Filter Maintenance

Right now is the perfect time of year to make sure you’re doing all you can to stay healthy. One of the easiest ways to tangibly benefit your health is to ensure your air is fresh, clean, and safe.

You likely already know that an air purifier is especially helpful at creating better indoor air quality. But air purifiers can’t perform properly without some routine maintenance. Completing some simple tasks, like routinely cleaning pre-filters and replacing filters when needed, helps keep your unit efficient and effective.

Below, we break down everything you need to know about air filter maintenance.

 

Is It Difficult to Maintain and Clean An Air Purifier?

If you've got an Airmega, you're in luck. It couldn't be easier to maintain and clean an Airmega air purifier. Airmegas require infrequent and minimal maintenance. They also have built-in features to indicate when it is time to change a filter (if you have any questions about when to change your filter, read our in-depth blog).

Still, there are a few things you'll have to do to ensure proper 24/7 air purification.

 

Why Is Air Filter Maintenance Important?

Before we get too far, it is important to define why air filter maintenance is important. If you have a Coway Airmega purifier that is no longer performing how it did when it was brand new, you may be tempted to purchase a new unit. But as much as Coway is dedicated to helping you live a better, healthier life, we also want a better, healthier world to live in.

We recommend regular product maintenance such as replacing filters because this will help your Airmega purify your air for years to come, thus avoiding unnecessary waste. Here are a few reasons you should prioritize air filter maintnance:

  • It saves you money: avoid damaging or replacing your product by keeping it running like new. This is especially helpful if you own multiple Airmegas or are purifying in your place of business.
  • It helps you stay healthier: old or dirty filters will be less effective in removing harmful airborne particles. Coway Genuine Filters keep your air clean and healthy.
  • It is more sustainable: by keeping your Airmega running for a long time, you can feel good about extending the life of your product and creating less waste.

 

5 Essentials For Airmega Air Purifier Maintenance

Okay, now that we have covered the basics, let’s take a look at how to properly care for your Airmega! We will walk you through general air purifier maintenance tips as well as show you how to care for individual Airmegas. 

Be mindful that some units have slightly different maintenance steps; however, one thing that all Coway products have in common is that they are very simple to maintain! 

And don’t worry: if you have any questions, refer to our FAQ video, which walks you through common maintenance questions.

1. Don't Forget to Remove the Plastic Packaging

When your Airmega arrives fresh out of the box, there's one crucial step that will ensure proper function. If you notice that your Airmega is making a loud noise, you may have skipped it! Remove the plastic packaging from the brand-new filters inside your purifier, then install them properly. Don't be that person who keeps their plastic packaging on for a whole year...oops!

Another important step for clean, fresh indoor air is to find the perfect spot for your Airmega. Generally, we recommend placing it at the middle of the spaces where you want clean air, like between a living room and a kitchen. It's also best to maintain about six to twelve inches of free space for wherever air flows in or out of your purifier. 

 

2. Use Coway Genuine Filters

Airmega purifiers are top of the line, and with some simple air filter maintenance, they'll keep your indoor air healthy for a long time to come. 

The same goes for our filters. Curious about the difference between Coway Genuine Filters and other 3rd party filters? While it may be tempting to save a few bucks and buy a 3rd party filter for your Airmega, there are a few reasons that these lower-quality filters are not a great choice, and may even end up costing you more money in the long run.

Here are some reasons we highly recommend selecting the appropriate Genuine Coway Filter:

  • Perfect Fit and Seal: Third-party filters will have a poorer fit and, therefore, won't seal properly in your air purifier. This means more fuss when swapping filters. It also means less effective air purification.
  • Higher Performance: Coway Genuine Filters are tested and re-tested to ensure the highest quality purification. We can't guarantee the effectiveness of other filters, but we know our filters perform excellently every time you switch on your Airmega.
  • Longer Lifespan: Our filters are made with the best materials, ensuring that they last a long time. Even if you find a cheaper third-party filter, it often has a much shorter lifespan than Coway Genuine Filters, so you'll likely end up spending more money because you have to replace it more often. 
  • Energy Efficient: Because Coway Genuine Filters are crafted to work perfectly with Airmega products, we can ensure the energy efficiency of your air purifier. Other filters may increase your Airmega's energy consumption due to poor fit and seal or lower quality filtration.

3. Know The Parts of Your Air Purifier

No matter how efficient your air purifier was designed, it won't filter well without a few basic filter maintenance steps. Let’s take a look at the general parts of your Airmega.

The first filter on your Airmega is the washable pre-filter, which keeps out large particles like dust and hair. Vacuum or rinse this filter every 2-4 weeks, allowing it to dry completely before reinstalling.

Check out the video down below explaining how important a clean pre-filter is!

 

Keep in mind: Your filters cannot be washed or reused. If your Airmega has a filter indicator light, you'll know exactly when it's time to reorder. A general rule of thumb is up to one year. If no filter indicator light is present, check your manual and pre-order your replacements for the specific recommended time.

For Wi-Fi-enabled devices, you can also use the Coway Smart Home to ask Alexa about your indoor air quality or to change the fan speed. You can additionally set up reorders for filters without having to even press a button. Once you've replaced the filter, remember to press the reset button!

 

4. Clean Your Air Quality Monitor

For the most accurate reading possible, you should wipe the air quality monitor on the side of your Airmega with a cotton swab. Doing this every two months or so will keep it clear of dust and ensure that it is giving you the most informative air quality reading. This is an important step to providing clean interior air.

5. Maintain Your Other Air Purifier Components

Setting up your Airmega and maintaining/replacing the filters when needed is important, but it is also useful to clean and maintain other components on your air purifier. We recommend that you wipe the exterior covers and air outlets with a dry, soft cloth at least every two months to ensure that air is flowing freely. Keeping these parts clean and free of built up particles helps keep the filters performing well and your Airmega cleaning the air as efficiently as possible.

Of course, every Airmega has its own best practices, so reference the manual provided if you have any specific maintenance questions. And don’t worry if you misplace it: your user manual is always available online on your respective Airmega product page!

 

 

Now, It's Time to Find Your Filter Replacements

Now that we’ve learned how to properly clean and care for our Airmega products, let’s take a look at the correct filters. Many of Coway’s newest Airmegas have even more convenient filter maintenance, as the Max2 cartridge design allows you to replace the filter set as a whole without spreading dust or other particles around.

The test was conducted in a 13.1ft3 chamber. Virus was aerosolized for 15 minutes and the product was turned on high for 2 minutes. Result showed each product effectively removed over 99.98% of the SARS-CoV-2 in 2 minutes. This is a result from a laboratory experiment condition and result may vary in different conditions.

5The coverage area of the air purifier is based on an area where the air cleaner can make two air changes per hour (ACPH). An air change per hour translates to how many times an air purifier can clean an area, assuming the height of a ceiling to be 8 ft, in one hour. Therefore ** means two air changes per hour means that the cleaner can clean the area once every 30 minutes and * means air changes per hour means that the air purifier can clean the area once every 60 minutes.
