How humidifiers work
Did you know that a humidifier could easily eliminate snoring? Humidifiers though disregarded by many families are essential for our health and can help keep infections away especially during winter. This is how they work:
When you turn on the furnace to heat the house, the moisture in the air is dried out and the air becomes a haven for bacteria, viruses, and other allergens. A humidifier’s work is to add moisture to the air thus minimizing bacteria multiplication.
The best 2 in 1 air purifier and humidifier eliminates the allergens in the air through filtration and at the same time, adds moisture to the air to maintain the desired level of humidity in the air.
A humidifier usually has a refillable water tank which allows it to consistently release water into the air. There are 2 classifications of humidifiers, console and whole-house units.
The whole house unit is usually joined to the current forced-air central heating system. This enables it to circulate moisture throughout the house via the furnace ductwork.
The console humidifier is a single room unit. Console humidifiers utilize a fan to spread water throughout the room. Most of the existing models can be moved from room to room or if possible, you can get one for each room.
Whole-house units require maintenance every 8-12 weeks depending on how hard the water is. On the other hand, console humidifiers need to be cleaned weekly and refilled daily.
How air purifiers work
An air purifier’s operation is pretty simple. Its main function is to filter air contaminants and release fresh air back. It sucks in the contaminated air using internal fans and the air passes through several filters.
The filters capture all the harmful particles, dust, pollen, mold and mildew, pet dander, bacteria, and viruses. Some filters like True HEPA filter can capture particles down to 0.3 microns at over 99.9% efficiency.
Once the air is filtered, the purifier releases it back to the air. Similar to humidifiers, most modern air purifiers can sense the air quality and automatically adjust the fan speeds.
Why is it good to have a combination of both?
Current research states that airborne contaminants as small as 10 microns or less can enter your lungs and trigger respiratory problems. The air inside the house is estimated to be 2 to 5 times more contaminated than the outdoor air.
Additionally, due to the frequent use of heating systems, the air lacks sufficient humidity for safe living.
Contaminated dry air is a health hazard. It’s a perfect breeding area for bacteria and viruses. There are uncountable benefits for investing in the best air purifier humidifier combo. Here are just a few.
Benefits of air purifier-humidifier combos
- An air purifier humidifier combo keeps airborne bacteria and viruses away. Allergens that could otherwise penetrate your lungs are captured, filtered, and fresh air is released back. Sufficient moisture in the air keeps nasal passages moist. This allows cilia (the hair that expels foreign particles) such as dust to work effectively.
- You no longer have to suffer unpleasant odors or smoke. Whether there’s a smoker in your house or you love cooking but fumes spread all over the house, you will enjoy an odor-free and smoke-free environment.
- An air purifier humidifier combo combats seasonal allergies. During extreme weather, we become susceptible to respiratory infections. Hay fever, asthma, cold, and flu become common. However, when the air within your house has enough moisture and is free of airborne allergens, your household remains safe.

- You get healthier skin. Skin irritation as a result of dryness ceases. Your skin becomes supple and smooth.
- Moisturizing the air also gets rid of static electricity. This reduces the effects on electronic equipment.
