The air exchange rate with the outdoors is a crucial factor in determining indoor air pollutant concentrations, according to the United States Environmental Protection Agency  Air purifiers circulate the air to give you better indoor air quality. Free flowing air also helps to regulate temperature and makes a finished basement more comfortable to live in.Fewer Allergens — There are numerous indoor allergens that show up in both finished and unfinished basements. Air purifiers are great for allergy and asthma sufferers because they trap allergens inside a filter so that the air downstairs doesn’t cause you to sneeze, cough, wheeze, or trigger an asthma attack.Less Pet Dander and Hair — If your pets have free range of your basement, then pet dander and hair can build up to uncomfortable levels. Air purifiers can reduce the number of dander particles and hair so it’s more liveable down there.Lower Dust Accumulation — Both unfinished and finished basements tend to accumulate a lot of dust. Air purifiers reduce these particles by circulating the air and trapping the dust inside a filter.Decreased Volatile Organic Compounds — Almost all building materials, paints, flooring, carpeting, and furniture release volatile organic compounds into the air which can cause odors and harm your health. Air purifiers remove these gaseous chemicals by absorbing the vapors before they get into your eyes, throat, or lungs.Extraction of Mold Spores — Basements breed mold more easily because they’re often damp, dark spaces, without great ventilation. Air purifiers can eliminate mold spores from the air by sucking them into a filter and destroying them with an ultraviolet light (more on that below).Fresher Smelling Air — With fewer mold spores, allergens, and dust in the air, your basement will smell cleaner and fresher when using an air purifier.Less Smoke and Odors — If you use your basement as a place to smoke tobacco, an air purifier can extract the visible smoke particles and strong odors that are usually left behind.Enhanced Mood Levels — Research shows that breathing in cleaner air improves your mood and decreases anxiety and stress. Air purifiers are perfect for anyone looking for better well-being.Improved Quality of Sleep — Polluted is known for disrupting your sleep and if your bed is in the basement, then you have all sorts of contaminants to contend with. Air purifiers can give you a better night’s rest by keeping the air around you clean.As you can see, air purifiers offer a number of benefits for improving the air quality inside a basement as well as your long-term health. It’s also why we recommend that you use one of these devices in other areas of your house.Key Features to Look for in a Basement Air PurifierNow, before you rush out and buy an air purifier, hoping that it will cure all of your basement air quality problems, there are a few things you need to look out for to ensure that you get the best product.Purchasing a device that has these features listed below will guarantee that you get the best air purifier for basement areas; both large and small, finished or unfinished.True HEPA Filter — Essential in a basement air purifier because it’s the only type that’s certified to capture particles as small as 0.3 microns. This includes mold spores, dust, allergens, smoke, pet dander, and thousands of other particles. However, watch out for air purifiers that use the words “HEPA-like,” “HEPA-type,” or just “HEPA” when referring to the filter. If it doesn’t have the word “True” attached to it, then it’s an inferior filter that won’t be the best for your basement.Ultraviolet Light — Also crucial because it’s the only air purification technology that can kill mold spores and other microbes. It works by using a beam of light to destroy the DNA structure of microorganisms. The UV-C light is completely safe for humans, however, it’s still contained inside the air purifier and doesn’t release any light into the room.Activated Carbon Filter — Another must-have feature because it’s the only type that can reduce basement odors. It does this through a chemical process called “adsorption” (which is similar to “absorption”), where odor particles cling to the filter medium. Activated carbon is the only substance that can remove a musty smell, volatile organic compounds, and other common basement odors.As you’ll see below, the top air purifiers we recommend for basements include all three of those features. It wouldn’t serve you well to buy a  basement air purifier that was missing any of these components.Choosing the Right Size Air PurifierThe next section will reveal the best air purifiers for basements.However, before you skip ahead, it’s important that you know which size air purifier you need so you don’t waste money or get one that’s not powerful enough for your needs.Sizing an air purifier is actually quite simple.All you have to do is match up the machine’s square footage coverage (sq. ft.) with the basement space.If the air purifier meets or exceeds the room size, then you can use it. If it doesn’t, you’ll need to look for a bigger device.In our reviews below, we tell you how much space each air purifier can handle.To find out who much coverage you need in your basement, follow these two steps:With a tape measure, measure the width and length (in feet) of your basement—or if you’re just using an air purifier in one room of your basement, measure just that room. Round each number up or down to get a whole number (they’re easier to work with).Multiply the width X the length to get your total square footage (sq. ft.)Here are two examples:An unfinished basement that measures 24′ x  16′ has 384 sq. ft. (24 x 16 = 384).A finished bedroom in a basement that measures 12′ 6″ x 14′ 2″ has 182 sq. ft. (by rounding to the nearest whole numbers, we get 13 x 14 = 182).Once you’re equipped with the square footage number, you can then find an air purifier that can handle it, which we’ll cover next.The Best Air Purifiers for BasementsNow that you know what to look for in the best air purifier for basement areas, and how to get the right size, you now have enough information to make a good buying decision.Below, you’ll find the four best products you can buy for your basement.
