Coway Air Filters vs. Third Party Filters

Seeing that filter indicator light come on can feel daunting, but replacing your Airmega filters is a breeze. With just a few simple steps, you can restore your air purifier to peak performance. This guide will walk you through the process, from selecting the right filters to properly installing them in your unit.

It’s time for a replacement

To maintain air quality, it’s important that you change your filters on time. Carbon filters need to be replaced about once every six months, and True HEPA filters about once a year, depending on how much air they have processed. Luckily, you can find countless versions of disposable air filters, from brand names to third party replacements that claim to fit your purifier’s model. But wait—before you click buy, there’s some fine print you should know about. 

There are no guarantees with third party filters

The standards of a Coway brand filter are as high as the modern purifiers themselves. This means using only True HEPA-certified filters, and top-quality carbon filters—each fitting snugly into your Airmega. Official Coway replacement filters are engineered for efficiency and effectiveness, and are the ultimate way to ensure pure air in your home or office.

You may save now, but you’ll pay later!

If the price of a replacement filter seems too good to be true, it probably is. Third party filters have been known to be less effective (in some cases, not effective at all) in reducing contaminants in the air.

When it comes to the air you breathe, it isn’t worth cutting corners

When it comes to the air you breathe, it isn't worth cutting corners. Every single breath you take impacts your health, energy levels, sleep quality, and even mood. Poor indoor air quality exposes you to unseen contaminants that can lead to allergies, asthma, and other health issues over time. Your Airmega air purifier is designed to combat these pollutants, trapping everything from dust and dander to odors and VOCs. But it can't do its job properly without genuine Coway filters specifically engineered for your model.

Generic third party filters simply don't measure up to Coway's rigorous standards. They may initially cost less, but you'll pay the price later with reduced performance and compromised air quality. Coway filters undergo extensive lab testing to verify their ability to capture pollutants, ensure a precise fit, and deliver purified air you can truly trust. When it comes to your health, don't gamble with knock-off brands. Insist on the Coway filters uniquely designed for your Airmega. Breathe easy knowing your air purifier is operating at peak purification power.

Alexa integration and smart reorder

With Alexa connected to Airmega, you can even set up a smart reorder through Amazon to keep your purifier running at its best—one less thing to put on the to-do list. Alexa will also help remind you when filters need to be cleaned or replaced, and will even place a replacement order through Amazon Dash.

3Aerosol test conducted in a Biosafety level 3 laboratory with two Coway air purifier models, Coway Airmega 250 and 400 for removal of SARS-CoV-2 Aerosol by US based MRI Global, a not-for-profit laboratory and partner of US Department of Defense. 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. This result does not imply it kills SARS-CoV-2 or prevents the transmission of Covid-19. Coway Airmega 250S and 400S are identical to the tested models and has equal performance with an additional mobile connectivity function.

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.
