What does air filter do in bedroom?

Placing an air purifier in your bedroom can significantly reduce the presence of airborne pollutants that can affect your sleep at night, especially if you put it on a nightstand near the headboard. Air purifiers contain one or more filters and a fan. The fan (or sometimes an internal fan system) draws in air and that air passes through the internal filters. These filters trap contaminants such as dust, pollen and bacteria, and disperse clean air back into the room.

This filtering process maintains healthy indoor air circulation. Keep checking the air filter gauge to change the filters at the right time and continue to enjoy a clean indoor environment. This air purifier is manufactured by a company called Blueair and its air purifiers are some of the most efficient and capable machines out there. If you also want to avoid odors and fumes, try air purifiers with HEPA and activated carbon filters.

For best overall results, select an air cleaner that uses an activated carbon filter in combination with other filters, such as a HEPA filter. To avoid these sleep interruptions, it's best to use HEPA air purifiers because they filter out most allergens in the room. Air purifiers can help clean the air in your home of unwanted particles, such as pet dander, allergens, and smoke. Some technologically advanced air purifiers include a combination of two or three types of filters.

If outdoor air pollution is high and you can't open windows, it makes even more sense to install an indoor air purifier, the Environmental Protection Agency (EPA) notes. Yes, air purifiers capture a high percentage of airborne allergens and irritants that flow through filters. An air purifier can work in conjunction with a high-efficiency particulate air (HEPA) filter, the latter of which is best known for trapping airborne allergens. This carbon filtration method uses a highly porous form of carbon to trap chemicals and recycle fresh air back to the room.

According to the Environmental Protection Agency (EPA), a portable air purifier is one of the most effective ways to improve indoor air quality in an individual room or area. A small-scale study conducted in China found that air purifiers reduced fine particles in the air (dust, pollen, dander) and improved participants' blood pressure levels and lung function. Before investing money in an air purifier, you should consider running an air quality test at home first to see if you need it.
