Benefits of Air Purifiers for Mold and Mildew

If you’ve got a mold and mildew problem in your home, you might think that it can easily be fixed by simply cleaning up the area with a disinfectant.

How Mold and Mildew Can Get into my Home?

Unfortunately, not only can that send millions of mold spores flying around into the air of your living space, it might not solve the problem.

That’s because mold doesn’t just grow inside your home, it also can be brought in through the wind coming through an open window or even on your body or your pet’s body.

Where to Check?

Mold pops up when we least expect it: after a cold spell, in warm, humid areas of your home where the heat is blasting.

It shows up in poorly ventilated bathrooms that host steamy showers or on your windowsills.

According to the CDC, the large majority of mold comes in through ventilation, pets, clothing and shoes, paper products, carpet and wood products.

If you don’t have an air filter or purifier, millions of spores are literally floating around in the air in your home, just waiting to be inhaled.

What these spores can cause?

According to Medical News Today, these spores can cause itchiness or sneezing. However, if left in your home long enough, they can even cause chronic lung conditions.

Benefits of the Purifiers:

There are huge benefits to purchasing an air purifier for mold.

True HEPA filter

If you purchase an air purifier with a True HEPA filter, you can rest easy knowing that even the most microscopic pieces of dirt and mold are not in your airspace.

Reducing allergens, pollen, and dust too

Not only will it remove mold, but it also reduces the presence of allergens, pollen, and dust too!

UV light technology

Similarly, the best air filters on the market feature UV light technology that zaps bacteria and viruses in the air that could make you sick.

Carbon Filter

Models with a carbon filter will also trap pathogens and molecules that are responsible for odd smells in your home that are related to your mildew and mold problem, but also smells that come from other sources, too.

In short, your air purifier will help keep your home and your family health in myriad ways.

Making The Decision Considering Most Important Factors

While there are so many air purifiers out on the market, if you’re willing to make the investment in your health and your home to improve the quality of the air you breathe, make sure you choose the best air purifier for mold and mildew for your family.

Size of the Room

First, consider the size room that you want to use the unit in. Potentially, you might need to buy a couple of purifiers to achieve the best results.

Type of the Purifier

Second, consider how much work you want to do. Ozone air purifiers cannot be used when you’re home and require that you do more cleaning to your home to eliminate mold.

HEPA filtration system

If you choose a true HEPA filtration system, you can choose models that are automatic, monitor the air quality in your home and even have multiple speeds or are Wi-Fi-controlled.

Finally, there are so many air purifiers that give users more benefits than just eliminating mildew and mold spores. Now, there’s a technology that removes bacteria, pollutants, pet dander, and even strong odors.

According to the CDC, airborne mold and mildew in the home can cause permanent damage to your lungs and health, so if you have concerns about the air quality in your home, the time to act is now.

Purchase an air purifier today and we promise you’ll see a dramatic increase in the quality of air in your home and in your life!
