What to consider when buying the best air purifiers for moldMold exposure can lead to a stuffy nose, sore throat, coughing or wheezing, burning eyes, or rash. People with asthma or who are allergic to mold may have severe reactions like shortness of breath or chest tightness. Immunocompromised people and people with chronic lung disease may get lung infections from mold. With all this considered, its important to find an air purifier that works. Heres what features you should consider before hitting add to cart:Size of spaceMost air purifiers are designed to clean the air in a single room. Because of this, many models include a Clean Air Delivery Rate (CADR) to show how fast it can purify the air in the room. The higher the CADR, the larger area an air purifier is able to clean. Generally, you should look for an air purifier with a CADR of 2/3 the square footage of a space. If youre looking to put an air purifier in a 100-square-foot room, youll need a minimum CADR of 65, per Energy Star. HEPAHEPA stands for high-efficiency particulate air and has been used since World War II. Thats pretty neat. If youre looking for a filter specifically for mold, look for H13 or H14 HEPA filters. Theyre the highest tier of filtration and are considered medical or hospital grade. Additionally, if you dont want to think about filter speed or changing settings as air quality changes, consider an air purifier with sensors that increase the amount of air filtered for you. A higher fan speed for a longer time increases the amount of clean air in your home. Mold preventionThe best air purifiers for mold only filter out spores already in the air. The CDC recommends keeping humidity levels no higher than 50% in your home to prevent mold. An air conditioner or dehumidifier can help, and you can buy a humidity meter to monitor levels in your home. Fix any roof, wall, or plumbing leaks, and add mold inhibitors to paint or use a mold-inhibiting primer before painting. You should also dry out your home 24-28 hours after a flood and remove or replace carpets and upholstery that have been soaked and cannot be dried right away. Bathrooms and basements often harbor the most mold since they get moist easily when not built properly. Surface mold growth, like on the tile or in the caulk, is easy to clean. Use a mold-killing cleaner like this Lysol shower spray with bleach or remove the caulk and replace it with the highest quality caulking you can find. However, removing mold growing behind the shower is a job for a contractor, unless you are the handyperson in your home. Should you test your home for mold? The CDC says no since the health effects of mold are different in everyone. Good mold sampling is often expensive, and there are no set standards for acceptable kinds and qualities of mold in homes. Color also isnt an indication of mold danger. Save your money to remove any mold in your home and keep it at bay.So, should you be constantly vigilant of mold? According to the CDC, probably not. There is a little mold everywhere. Molds that may be toxigenica.k.a., they produce toxins, specifically mycotoxinsare as hazardous as the common molds in your home. There are few reports that toxigenic molds in homes can cause pulmonary hemorrhage or memory loss. A link between the two has not been proven, and these reports are rare.If you have asthma, are allergic to mold, are immune-compromised, or have chronic lung disease, talk to your doctor about what you can do to protect yourself against mold.Smart capabilitiesSome air purifiers can be controlled via an app that gives you deeper insights into the air in your home. Some have internal sensors that detect the air quality in your home and adjust the filter speed accordingly. However, these features can hike up the price. If you get annoyed with air purifiers beeping when the air quality is poor, look for something that lets you turn the signal off, or consider a model that is beep-free. You already cant stand when you set the fire alarm off while youre cooking. You dont need any more unnecessary beeping in your life. MaintenanceAir purifiers require some montly upkeep to keep them performing their best. If you have petsparticularly those that leave fuzzy tumbleweeds all over the housevacuum the pre-filter (aka, the opening where air enters the filter) to remove any fur that has accumulated against the outside.
