The answer is a resounding yes! Most air purifiers on the market are designed to remove large dust particles from the air. Many of them use mechanical filtration, which is a method of capturing contaminants in filters. For the best results, HEPA-filtered air purifiers are the way to go. According to the Environmental Protection Agency (EPA), these filters can remove up to 99.97% of dust particles that measure 3 microns in diameter.
Air purifiers can be effective in removing dust indoors and improving asthma and allergy symptoms. Air purifiers usually consist of a filter, or several filters, and a fan that draws in and circulates the air. If you suffer from routine allergies or asthma, evidence that a HEPA filter improves respiratory health may encourage you to seek an air purifier. The EPA states that devices with a high-efficiency particulate air filter (HEPA) can remove 99.97% of particles in the air with a size of 0.3 microns.
If outside air enters the home, air purifiers reduce pollutants, but cannot completely eliminate them. Placing an air purifier in every room is a great way to collectively remove dust from the air. It's important to buy the right size air purifier for the job. This is the amount of clean air your device spits out in cubic feet per minute.
The “Vital Ion” filter is not an ionizer, so you don't have to worry about breathing ionized air. To effectively remove harmful pollutants from the air, it would be useful to use an air cleaner with a quality particulate filter for dust. Air purifiers with true HEPA filters can effectively remove contaminants indoors with closed doors and windows. In fact, they can neutralize some of the threat posed by air pollution and indoor activities.
The best HEPA air purifiers come with an activated carbon filter to effectively absorb smoke, chemicals, or any unpleasant odors in your indoor environment. However, without other methods of removing dust, such as proper ventilation and stopping contaminants at their source, the EPA suggests that air purifiers are quite powerless in reducing indoor air pollution levels, including dust. 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. According to the EPA, the higher the clean air supply rate (CADR), the more ground your air purifier can cover and the more effective it will be.
