How Exposure To Mold Can Affect Your Health

Not everyone has an allergy to mold and mildew. Those who do, however, will notice things like coughing, stuffy nose, wheezing, and irritated throat as some of the common symptoms. Some people don’t get an allergic reaction to mold, but this doesn’t mean it’s not harmful to your health. Exposure to indoor mold can cause problems to your upper respiratory system, wheezing, and coughing in a healthy person. It can also lead to the development of asthma in children if exposed early to mold.

The potent toxins produced by indoor mold and mildew are not only absorbed by your lungs, but also your skin and intestines. Long-term exposure can lead to serious problems to your health that include memory loss, cancer, cardiac conditions, neurotoxicity, etc.

Mold can become a very huge problem very fast because it reproduces to millions of tiny spores that can survive where visible mold can’t. Once these spores land on a surface, they begin to grow, which causes serious health problems. Different types of mold outside can enter your home very easily through the vents, doors, windows, or by attaching themselves on your clothes.

That’s why it’s important to use the best air purifier for mold to control this problem. An air purifier will get rid of all kinds of mold and improve the quality of your life.

Key Features To Look For In The Best Air Purifier For Mold

Speed or cleaning levels

An air purifier with different fan speeds is very helpful because it can control the air circulation in a particular room. Mold is most prevalent during the cold and damp months. This is the best time to increase the speed of the fans to the highest level to thoroughly clean the air. During warmer days, you can turn the fan speed down since it’s easy to naturally ventilate your home by opening the windows and letting the sun in. Some air purifiers come with a smart sensor that changes the fan speed if the quality of air changes.

Filter efficiency

Look for an air purifier that has at least two stages of filtration. It should also have a HEPA filter and an activated carbon filter to make sure that it captures the mold spores in the air together with their odor.

Coverage area

Different air purifiers can cater to different room sizes. For example, some models can handle a 400-square foot room, while another can handle a 1000-square foot room. It all depends on the size of the room you need to purify. It could be a small, medium, or a large room or office space. Ensure you get the right air purifier for the job.

Automatic mode

The automatic mode in the air purifier enables the machine to assess the quality of air in the room. If it senses a change like the presence of smoke, impurities, or odors, it increases the speed of the fans to clean the air. This means you don’t have to manually adjust the machine every time you notice a change in the air you’re breathing. The purifier will do that for you.

Noise and lights

Some air purifiers can be very noisy with lots of lights, while others are a bit quieter. This may not be a very important point as far as the best air purifier for mold is concerned, but it’s worth noting if you get irritated by noise and bright lights.

HEPA filter

The HEPA filter can capture the tiniest mold spores in the air which makes it very efficient in getting rid of your mold spore problem. You will find air purifiers with true HEPA filters, others with the HEPA style filters, and others with HEPA grade filters. It’s best to find an air purifier with a true HEPA filter. If you have budget constraints, get one with the HEPA grade filter.

The mold spores die once sucked into the HEPA filter because it’s a dry and sterile environment that isn’t conducive for their survival. Also, look for purifiers with antimicrobial filters that will help kill the mold spores in damp environments and an activated carbon filter to help clear the air of the moldy and misty odor.
