Buying Guide
Air purifiers use a fan to pull air impurities into filters to trap them before circulating fresh, clean air back into the room. The first thing to consider when investing in an air purification system is size. Air purifiers are available in many sizes and can cover different square footage amounts, so you will want to measure the size of the room you plan to use it in. This makes sure the purifier will function efficiently and effectively, so that you won’t spend more money or use more energy than necessary. After you know the square footage of the room for your air purifier, it is time to decide on a filtration method. There are many choices, but the most common are HEPA (high-efficiency particulate air) and carbon. HEPA filters remove 99.97% or more of airborne particles like dust, pollen, bacteria, and mold. Carbon filters absorb odors from smoke, cleaning chemicals, personal care products and other air contaminants. Using an air purifier with both types of filtration will remove more pollutants as the filters work together for maximum efficiency. Another thing to consider is the cost. Air purifiers can range in price from around $50 to over $1000. Before setting a budget, keep in mind that the two most important factors are the 99.97% removal of air pollutants and the square footage requirement of your room. You also may want to see if a warranty and customer support are included with your purchase so your clean, fresh air will be a worry-free, long-lasting investment.
