Hosting for the Holidays? Here's How to Ensure Clean Air for Your Guests
The holidays are a time for togetherness, warmth, and plenty of activity, but all that gathering can make your home’s air work overtime, especially considering flu and holiday season coincide.
Between cooking, candles, guests, and closed windows, indoor air can quickly fill with particles and odors you don’t even notice. Luckily, with a few easy steps and a little help from your Coway Airmega, you can make clean air part of your holiday hospitality.
Start Fresh Before Guests Arrive
A quick pre-holiday refresh sets the tone for the season. Give your Airmega a few minutes of attention: clean the washable pre-filter, wipe away any dust on the exterior, and check whether it’s time to replace your main filters. Most models include a filter indicator light that will turn on when it’s time for a swap. If it’s illuminated, replace your filters with Coway Genuine Filters — they’re designed for a perfect fit and long-term efficiency.

While you’re at it, think about placement. Your Airmega should sit where air flows freely (ideally in a central room or near the main gathering space) with a few inches of open space on each side. This ensures clean air circulates evenly, no matter how lively things get.

Keep It Clean During the Celebration
Cooking big meals, burning candles, and hosting extra people all increase airborne particles. To keep your space feeling fresh:
- Use your range hood while cooking and keep your Airmega running in Auto Mode nearby.
- Open a window for a few minutes when the weather allows, even a short burst of outdoor air helps.
- Let the Airmega run continuously while guests are over; it automatically adjusts air flow as air quality changes.
- Set to Sleep Mode when the night winds down to maintain quiet, gentle purification while everyone rests.
Your Airmega’s air quality indicator will keep you informed. You’ll see color changes as it detects shifts in the room’s air, automatically adjusting the filtration in real-time.

After the Guests Head Home
Once the dishes are done and the house quiets down, a few small steps help reset your space. Wipe surfaces, vacuum, and wash guest linens.
Then, give your Airmega one last once-over: clean the pre-filter, check the sensor area for dust, and confirm the filter light is off.
If your filters are due for replacement, swap them now so your home stays fresh for the new year. It’s easiest to set up a filter subscription so you don’t have to worry about remembering this last step!
Why Does Air Quality Matter at Gatherings?
When our homes fill with people, food, and festive energy, indoor air changes fast. Maintaining your purifier is just as important for your health as it is for your comfort. That’s because clean air supports better rest (and did you know air quality is worse at night?), easier breathing, and a more welcoming environment for everyone.
With your Airmega working quietly in the background, guests will simply feel the difference!

Holiday Air Quality FAQs
1. How can I make sure my Airmega is ready for guests?
Clean the pre-filter, wipe the exterior, and check the filter indicator light. If it’s on, replace with Coway Genuine Filters before your event.
2. Can I leave my Airmega running all day?
Yes. Airmega purifiers are designed for continuous use, automatically adjusting speed based on real-time air conditions.
3. Does placement really matter?
Absolutely. Keep your purifier away from walls and corners so air can move freely through the intake and outlet vents.
4. How often should I clean or replace filters during winter?
The pre-filter should be cleaned every two to four weeks. The Airmega’s main filter typically lasts six to twelve months, depending on use and air quality.
5. What if I have pets or a full house for several days?
Consider running your Airmega on Auto Mode around the clock. You can also add a second purifier in a high-traffic or pet area for extra coverage.
A little preparation goes a long way toward making the holiday season more comfortable. With your Airmega maintained and running smoothly, you can focus on what really matters: good company, great food, and air that feels as fresh as the occasion itself!

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.
