With the winter season underway, you’re probably spending a lot of time indoors. It may come as a surprise to you, but the air we breathe indoors can potentially be more polluted than outdoor air. That is why it is important to arm our homes with an air purifier that can effectively remove year-round offenders such as mold, dust mites, pet dander, and viruses. In addition to freshening up the air, it can also decrease the chances of allergic reactions, respiratory issues, and other related health problems.

Together, they efficiently capture up to 99.97% of the tiniest contaminants, particles, and pollutants. It’s also powerful enough to eliminate over 99% of organic compounds and reduce fumes such as acetaldehyde and ammonia. Larger particles like fur and hair are also taken care of, thanks to the washable and permanent pre-filter.

By using powerful dual-suction technology, this Coway air purifier is able to draw contaminated air in and push filtered air out. It cleans the air at least two times per hour and communicates real-time indoor air quality through the built-in pollution sensor. Its LED ring will turn into a specific color brightly so you can quickly identify how clean or dirty the indoor air is every minute. Blue means good, green is for moderate, yellow is for unhealthy, and red signifies very unhealthy.

Perhaps what makes this Coway Airmega 300 stand out is its smart functionality. Its Smart Mode feature enables it to adapt to its surroundings by automatically adjusting the fan speed based on the room’s air and lighting conditions.
