If you’re concerned about the quality of air within your home, an air purifier & filters can be a great option. From smoke to allergens to bacteria, the air in your home could be rife with things that aren’t good for you. A high-quality air purifier can deal with just about all of that pretty effectively. Of course, it’s important to understand exactly what you’re looking for in an air purifier. First, their listed efficiency is typically only at their highest setting. This is why it’s important to find purifiers with a CADR (clean-air delivery rate) of at least 300 and also look for an Energy Star certification.
Electrostatic air cleaners are a popular type of air purifier, and they work by creating an electrically charged panel which captures allergens and other airborne debris. These are great at capturing even the smallest particles, but they do require you to clean up the particles after they’ve fallen on your floor and gathered there. Gas-phase air filters are especially efficient at preventing gases and odors from infesting your home. These are less common in household areas, however, since they have a very short lifespan.
UV air filters are a newer technology on the market and, as such, little has yet been proven regarding their efficiency one way or another. They are, however, able to handle even the smallest airborne dirt, including mold and bacteria by targeting it with ultraviolet light. If you combine these with a filter-type device, you typically can create a very effective home defense system. When choosing your filter, remember that air filters can be expensive to replace, so you may want to consider a system with a cleanable filter instead. Also, do your research with Consumer Reports to make sure you’re working with a reputable brand.
