7 Reasons A Coway Filter Subscription Is Essential For Healthy Homes

Indoor air quality might not be something we think about often, but it has a huge impact on our health and well-being. With Americans spending 90% of their time indoors, the air inside our homes and offices needs to be clean, healthy, and free of harsh pollutants. Investing in a high-quality air purifier is a great start to protecting your health and the health of your family. But upgrading to a filter subscription is the best way to ensure that protection doesn’t have an expiration date.

Read on to learn all about our new air filter subscription program and why it’s essential for a healthy home.

All About Air Filters

The goal of air filters is to trap the pollutants the air purifier suctions from your space. As one of the leading manufacturers of air purifiers and filters, Coway has a range of innovative products that use advanced filtration to remove harmful contaminants from your space air, including allergens like flower and tree pollendust, odors, smoke, mold spores, bacteria and viruses.

But none of this purification would be possible without the right filters. Max2 filters from Coway leverage a multi-stage filtration system with up to three different filters working together to fully purify your space.

What Goes Into A Max2 Filter?

Coway’s engineered filtration provides the most effective and efficient purification of your space by utilizing the power of Max2 Filters. Each part of the filter targets different pollutants:

  • Activated carbon filter: Absorbs gaseous pollutants and odors.
  • True HEPA filter: Traps ultrafine particles down to 0.01 microns, including allergens, bacteria, viruses and smoke.

To keep getting peak performance, these filters need to be cleaned and then replaced regularly. This is where Coway's convenient filter subscription programs come in. We take the guesswork out of filter maintenance by shipping you new replacement filters automatically.

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.
