A home doesn’t have to be dirty to have problems with mold. It can appear just about anywhere indoors where you have high temperatures and high humidity levels. If it’s not treated quickly and effectively, mold can cause a whole a range of problems, not just to the house, but to your health as well. But don’t despair as there are steps you can take to help eliminate mold and keep it at bay. One of which is to invest in a decent air purifier.

In this article, we’ll go over in more detail why you need to steer clear of mold and mildew and how to best banish it from your home. We’ll also explain how an air purifier works and how it can help calm this situation, improving your indoor air quality in an instant.

Following on from that, we’ll then point you in the right direction of some of the best air purification systems available now for tackling mold within the home.

Why Mold Needs to be Avoided 

There’s quite a range of adverse effects mold spores can have on your health including the onset of allergies, asthma, chemical sensitivity flares, and respiratory problems. And these are just the short-term effects. Long-term exposure to mold is much more serious. Symptoms related to long-term exposure to mold include cancer, neurotoxicity, hypersensitivity pneumonitis, and pulmonary injury.

Mold spores reproduce by releasing spores into the air. They float around the air until they find a damp surface to cling to. Then, as long as the surface remains damp, the mold spores are fed. And eventually, they start to reproduce. The spreading of mold can happen very rapidly so it’s important to deal with it as soon as it’s detected.

Where Mold is Most Likely to be Lurking 

As mentioned earlier, mold can appear anywhere that’s moist and humid. If the humidity indoors is above 60%, this is the perfect breeding conditions for mold. Finding a large source of mold in the home could indicate a much deeper problem such as poor ventilation or leaking pipes. Whatever the source may be, it still needs to be treated. In worst cases, if mold is left untreated, apart from the damage it could do to your health, it could even cause the decaying of your home.

Quite often, in properties of poor ventilation, mold spores will form around the edge of the window, typically in the corner. In the bathroom, however, you may notice spots of mold appearing just about anywhere. Both the shower and bathtub are very common as these areas tend to be damp quite a lot. The sink and toilet are in the same boat. However, you also need to look closer. Mold is very good at hiding and is also likely to appear in places such as shampoo bottles, shower heads, and toothbrush holders as all offer the perfect conditions for reproducing.

How Air Purifiers Can Help

There are various types of air purifiers available. However, not all of them are effective at mold removal, so you need to be careful. Any air purifier that’s fitted with a True HEPA filter will definitely help as these filtration systems physically trap the mold, preventing them from reentering the atmosphere. Ideally, when dealing with mold, you should also choose a model that’s fitted with an activated carbon filter. These filters are specially designed to tackle odors and are the only kind strong enough to deal with mold.

Another good feature to look for is those fitted with a germicidal UV-C light. These are the most effective at stopping mold spore reproduction. While there is some controversy over whether UV light should be used in air purifiers because of its potential danger to humans, it is contained within the system itself and therefore should eliminate any associated risk. As air passes through, it’s exposed to UV-C light, destroying any mold spores’ DNA, making it impossible for it to reproduce.

While air purifiers won’t completely solve your mold problem, it’s certainly a good place to start. According to the Environmental Protection Agency’s (EPA) Guide to Air Cleaners in the Home,  while both portable air cleaners and HVAC filters may be effective at removing some mold spores, they won’t solve an ongoing mold and moisture issue. To do this, more specialist equipment will be required. But if you’re looking to remove naturally occurring mold spores from your indoor air then an air purifier is a good tool to help.

Preventing Mold Growth 

It’s one thing tackling mold that’s already there, but it’s another thing altogether, preventing it from returning. However, if you want to continue breathing in fresh and uncontaminated air, then both must be adhered to. One way to keep on top of any mold problems within your home is to periodically tour your property looking for cracks in the walls, or any signs of leakages. You should also ensure that all potential entry points for water are sealed. This will also help shield the property from wind, helping to keep your home warmer in the winter.

If you do detect any signs of serious mold, contact the professionals who can treat this problem immediately for you. Once the current problem has been rectified, your air purifier will work much more effectively at providing you with a constant supply of clean air.

When you do have your own air purifier in operation at home, make sure you change the filters on a regular basis, especially if living with any elderly people or those with any underlying health problems. While many of the high-end models have integrated filter replacement monitors, some of the budget models are a little less intuitive and will need to be checked manually every few weeks. If it looks dirty or clogged, then replace it. If you read the manufacturer’s guide, it should give you a better indication of how often the filter will need changing.
