Room Air Purifiers - Ideal for Spaces Under 500 Square Feet
| Room air purifiers are designed for spaces less than 500 square feet. Simply plug these units into a standard outlet and place it in the room you spend the most of your time in. Many units are powerful enough to effectively purify the air of contaminants such as pollen, pet dander, and more. Before you decide on a specific unit, determine what your needs are. For example, if you're looking for an air purifier to help alleviate allergies, make sure you choose a room air purifier with a HEPA filter. If you're concerned with odors or smoke, consider a room air cleaner with activated carbon. Need more help? Check out our air purifier buying guide! |

Top 3 Air Purification Technologies DemystifiedWith so many types of air purifiers available on the market today, it's often hard to determine exactly which model is best for you. Before you make a purchasing decision, take some time to familiarize yourself with the different air purification technologies out there. Here's an overview of some of the 3 most common ones: HEPA Filters: By definition, HEPA filters must be capable of capturing 99.97 percent of particles up to 0.3 microns in size and it's for this reason that they're one of the most effective types of filters for particle abatement. HEPA air filters were developed by the Atomic Energy Commission during WWII to remove radioactive dust from their plants. Since then, they've been in use by the U.S. Department of Homeland Security. Choose a room air purifier with HEPA if your main concern is dust, pollen, dust mites, and other allergens. Activated Carbon Filters: Activated carbon is one of the most absorbent filters available. Activated carbon is essentially charcoal that has been treated with oxygen. These pores adsorb harmful gases and odors. If you're concerned with chemical fumes, cigarette smoke, or odors, look for an air purifier with an activated carbon filter. Ionizers: Ionizers create negative ions which change the polarity of airborne particles. This causes them to attract together and onto a magnetic collection plate. Air purifiers with only ionizers are usually pretty quiet, so they're a good choice if you don't like the noise produced by an air purifier with mechanical filtration such as HEPA.
