How To Improve Indoor Air Quality Throughout The Winter

Unfortunately, poor air quality inside the home throughout the winter can seriously affect your comfort and welfare. The moistness increases as the temperature drops. This, combined with the propensity to yank on your heater, creates moisture-drained air that dries out your skin, irritates your breathing passages, and aggravates symptoms of cold and sensitivity. Additionally, weatherizing your home will keep dangerous contaminants inside while helping to improve the efficiency of your heating system by sealing out unconscious air. This suggests that you consume more allergens and could be exposed to higher concentrations of chemical contamination. That must be a horrifying thought, right? Fortunately, an air washer is useful.

Why Should We Use Air Washers?

The clever tiny air quality machines known as air washers have long been popular in Europe. A hybrid device that combines both an air purifier and a humidifier is called an air washer. Air washers impart beneficial wetness to the air, much like conventional humidifiers. An air washer also removes allergens from the air that cause symptoms, just like a standard air purifier. They are therefore prepared to ease your uncomfortable dry air manifestations and accommodate your sensitivity. They’re excellent for you if you believe that light to direct allergens cause you discomfort or if you just want to improve the quality of the air inside your home throughout the winter.

If you reside in a dry region, you might also think about using one all year long.

How Does A Basic Air Washer Operate?

Air washers offer moisture to the air while removing a variety of allergens, such as dust, dust mites, pet dander, pet hair, form spores, dust, and other airborne particles. The most popular types of air washers employ impeller technology. This technology continuously screens out allergens and other particles from the air as it enters the device using a series of rotating plates (often at least 30 or more). Huge amounts of allergens amass on the plates as a constant stream of water washes them away and collects them at the base of the appliance.

Then, the plates propel pure water through a remarkable diffusing screen, separating it into a fine fog that fills your air. Most tabletop devices have a daily moisture dispersal capacity of about one gallon.

Another unusual type of air washer uses a molecular pre-filter to screen out allergies and other contaminants from incoming air before humidifying your space. These models bring moisture to your space by using evaporative humidifying technology. The evaporative wick filter, which “wicks” up water while a fan blows to create a fine fog, is often equivalent to the pre-filter. If you have hard water, this filter also removes mineral deposits from the water, which is a bonus.

How Should I Select An Air Washer?

There are a few things to think about before buying an air washer whenever you plan to get one.


Your choice of air washer will mostly depend on your preference for humidification technique. For example, evaporative humidifiers work well in larger rooms because they use internal fans to distribute humidified air to virtually every corner of the room. Impeller humidifiers, on the other hand, are fanless and more suited for smaller rooms. For example, filter-based air washers will need their filters changed periodically, increasing your operating costs.


The majority of air washer humidifiers on the market today are practical tabletop models that, taking everything into account, will only treat one room. In any event, each model may handle a room of a different size and provide roughly the same amount of moisture every day. Look for a suggested square foot inclusion region in the model specifics while browsing and compare it to the size of your room. To ensure perfect humidifying and air cleaning, think about choosing a somewhat larger air washer than you might think you’ll need.

Added features help to make an air washer easier to use and maintain. Look at the component lineups for each model while buying and decide if there are any must-have highlights on your list. Numerous fan speeds, computerized controls, a flexible humidistat, a low-water indicator with a scheduled shutoff, a filter change indicator, and a scent holder, among other features, are well-known air washer highlights.

Water is sprayed into the air in a duct by means of air washers. They can be used only for dehumidification or for cooling and dehumidification.

The washing water is kept sprayed at a constant 10°C by the chiller. This enables the cooler air entering from the washer to condense water vapor as it falls into the pan. Because the chilled water is colder than the dew point (saturation temperature) of the air, more water is removed from the washer than was provided. The quantity and quality of the spray nozzles employed, as well as the rate at which air moves through the system, all affect how successful the washer is. The more moisture is condensed from the air by the water spray the longer the air is in contact with it.
