You’ve probably wondered if there’s much difference between an air filter and air purifier. The quick and simple answer to this question is ‘YES’. Although they both work to alleviate contaminants inside your home, they do it in very different ways.
How Does an Air Filter Work?
Air filters for the home are part of your HVAC system. They allow air to re-circulate back through your home after filtering out impurities such as pet dander, dead skin, cigarette smoke, pollen, among others. The air filters help your HVAC system run at peak performance and extend the life of the HVAC unit by keeping dust and dirt from entering the ducts. Over time, the filter will become clogged with the debris that it removes from the air, loosing efficiency. This is why it’s so important to replace your air filter every 30 to 90 days, depending upon the filter type.
A clean air filter has a tremendous impact on the quality of air inside your home. Air filters for allergy season can help alleviate a number of uncomfortable symptoms, including runny, stuffy nose, sneezing and wheezing by catching allergens in the air.
What Does an Air Purifier Do?
A typical air purifier uses the same method for filtration to remove pollutants from the air such as cigarette smoke, pollen, dust, etc. In this way, it removes the same sort of impurities that home air filters do, and some people use them to specifically remove odors.
There are several types of air purifiers and each work a bit differently. You just have to pick the better fit for your needs. For example, the activated carbon purifier is commonly used to remove odors from the air, but falls short when it comes to removing pollen, dust or other fine particles.
